    Descriptive Report on the Invention Patent for the Biopsy Actuator Set to Assemble a Biopsy Probe Set and Biopsy Apparatus.
    Background of the Invention
    Field of the Invention [001] The present invention relates to a biopsy apparatus and, more particularly, to a biopsy trigger assembly having a control circuit for conserving battery energy.
    Description of the Related Art [002] A biopsy can be performed on a patient to help determine whether the cells are cancerous in the region where the biopsy is performed. A type of vacuum-assisted biopsy device includes a manual trigger assembly that has a vacuum source and a disposable biopsy probe assembly configured for releasable attachment to the trigger assembly. A biopsy technique used to assess breast tissue, for example, involves inserting a biopsy probe into the region of interest in the breast tissue to capture one or more tissue samples from the region.
    [003] The biopsy probe typically includes a biopsy cannula, for example, a needle, having a cylindrical side wall that defines a lumen and having a lateral sample notch located near the distal end, which extends through the wall lateral of the lumen. A cutting cannula is positioned coaxially to the biopsy cannula to selectively open and close the sample notch. Vacuum is applied to the lumen and, in turn, to the sample notch, to receive the tissue with which the sample is made when the sample notch is opened, after which the sample notch is closed by the cutting cannula to separate the tissue and the separated tissue is transported by vacuum out of the lumen, being collected.
    [004] Such a hand-held trigger assembly runs on battery.

    The hand held trigger assembly is switched on at the beginning of the procedure and remains on for the duration of the procedure and / or until a user intervenes to turn off the hand held trigger assembly. As such a hand-held trigger assembly can be used for extended sessions, it is important that energy consumption is kept to a minimum to prolong battery life and prevent malfunction due to power failure.
    [005] US 2005/0165328 A1, for example, describes a hand-held biopsy device powered by battery. Arrangements for conserving battery power are known in other technical fields, as described, for example, in US 2008/0232604 A1, US2008 / 0110261 A1 or WO 2008 / 032.98 A1.

    DETAILED DESCRIPTION OF THE INVENTION [0033] Now, with reference to the drawings, and more particularly to Figures 1 and 2, there is shown a biopsy apparatus 10 that generically includes a biopsy trigger assembly, non-invasive, non-disposable, 12 and one disposable biopsy probe set 14.
    [0034] Also with reference to Figure 3, the driver assembly and disposable biopsy probe assembly 14 collectively include a fluid management system 16 that includes a vacuum source 18, first vacuum path 20 and a second vacuum path 22. The vacuum source 18 and a first vacuum path 20 are permanently associated with the driver assembly 12 and a second vacuum path 22 is permanently associated with the disposable biopsy probe set 14, as described in more detail below, to help facilitate the safe and effective collection of a sample
    Petition 870190089868, of 9/11/2019, p. 11/46
    9/35 tissue for biopsy.
    [0035] As used, the term non-disposable is used to refer to a device that is intended for use in multiple patients during the life of the device and the term disposable is used to refer to a device that is intended to be disposed of. after use on a single patient. In addition, the term vacuum path refers to a fluid passage used to facilitate a vacuum between two points, with the fluid passage passing through one or more components, such as one or more tubes, ducts, couplers and interposed devices. In addition, the term permanently associated means a connection that is not intended for fixable release on a routine basis during the life of the components. Thus, for example, the driver assembly 12, which includes the vacuum source 18 and the first vacuum path 20, can be reused as a unit in its entirety, while the disposable biopsy driver assembly 14 and the second vacuum path 22 are disposable as a unit in their entirety.
    [0036] The driver assembly 12 includes a housing 24 configured and ergonomically designed to be picked up by a user and to which the electrical and mechanical components of the driver assembly 12 are coupled, that is, mounted. The driver assembly 12 includes (contained within the housing 24) vacuum source 18, first vacuum path 20, a controller 26, an electromechanical power source 28 and a vacuum monitoring mechanism 30. A user interface 32 is located to be mounted on, and to be externally accessible with respect to housing 24. Housing 24 defines an elongated cavity 241 that is configured to receive a corresponding housing 57 of the biopsy probe assembly 14 when the driver assembly 12 is mounted on the probe assembly of biopsy 14.
    [0037] Controller 26 is communicatively coupled to the source of
    Petition 870190089868, of 9/11/2019, p. 12/46
    10/35 electromechanical energy 28, vacuum source 18, user interface 32 and vacuum monitoring mechanism 30. Controller 26 may include, for example, a microprocessor and associated memory to execute program instructions to perform functions associated with recovery from biopsy tissue samples, such as controlling one or more components of the vacuum source 18 and electromechanical energy source 28. Controller 26 can also execute program instructions to monitor one or more conditions and / or positions of biopsy device components 10 and monitor the state of the fluid management system 16 associated with the driver set 12 and the biopsy probe set 14.
    [0038] User interface 32 includes control buttons 321 and visual indicators 322, with control buttons 321 providing user control over various functions of the biopsy apparatus 10 and visual indicators 322 providing visual feedback of the status of one or more conditions and / or positions of biopsy device components 10.
    [0039] The electromechanical power source 28 may include, for example, an electrical power source, for example, battery, 34 and an electric drive assembly 36. Battery 34 may be, for example, a rechargeable battery. The battery 34 supplies electrical energy to all components electrically energized in the biopsy apparatus 10 and thus, for the sake of simplicity in the drawings, such electrical couplings are not shown. For example, battery 34 is electrically coupled to vacuum source 18, controller 26, user interface 32 and electric drive assembly 36.
    [0040] In the present embodiment, the electric drive set 36 includes a first drive 361 and a second drive 362, each of which is coupled, respectively, to battery 34 and each of the first drive 361 and second drive
    Petition 870190089868, of 9/11/2019, p. 13/46
    11/35
    362, respectively, electrically and controllably coupled to the user interface 32.
    [0041] The first drive 361 can include an electric motor
    381 and a motion transfer unit 401 (shown schematically by a line). The second drive 362 can include an electric motor 382 and a movement transfer unit 402 (shown schematically by a line). Each electric motor 381, 382 can be, for example, a direct current (DC) motor, a stepper motor, etc. The movement transfer unit 401 of the first drive 361 can be configured, for example, with a rotational-to-linear motion converter, such as a worm gear arrangement, a rack and pinion arrangement, an arrangement of solenoid, etc. The movement transfer unit 402 of the second drive 362 can be configured to transmit rotary movement. The first drive 361 and the second drive 362 can include one or more of a gear, a gear train, pulley and belt arrangement, etc.
    [0042] The vacuum source 18 is electrically coupled to the battery 34 and has a vacuum source port 181 to establish a vacuum. The vacuum source 18 is electrically coupled and attachable to the user interface 32. The vacuum source 18 can further include, for example, a vacuum pump 182 driven by an electric motor 183. The vacuum pump 182 can be, for example, a peristaltic pump, a diaphragm pump, a syringe pump, etc.
    [0043] The first vacuum path 20 of the driver assembly 12 is permanently associated with the vacuum source 18. The first vacuum path 20, also sometimes referred to as a non-disposable vacuum path, has a proximal end 201 and a distal end 202 and includes, for example, conduits 203, a first
    Petition 870190089868, of 9/11/2019, p. 14/46
    12/35 one-way valve 204, and a particulate filter 205. The proximal end 201 is fixedly coupled to the vacuum source 18 in fluid communication with it, for example, is fixedly connected to the vacuum source port 181 of the source vacuum 18. With reference also to Figure 4A, the distal end 202 includes a first vacuum sealing element 206. In the present embodiment, the first vacuum sealing element 206 is a flat bearing surface surrounding a first passage 207 of the first vacuum path 20.
    [0044] The first one-way valve 204 is configured and arranged to allow a negative pressure fluid flow towards the vacuum source 18 and to prevent positive pressure fluid flow away from the vacuum source 18 towards the vacuum source. distal end 202 of the first vacuum path 20. The first one-way valve 204 can be, for example, a check valve, such as a ball valve or non-return valve, which opens with a flow of fluid in the direction of the vacuum source 18 and closes in case of a reverse (positive) flow away from the vacuum source 18.
    [0045] In the present embodiment, the particulate filter 205 is located between the vacuum source 18 and the distal end 202 of the first vacuum path 20. The particulate filter 205 can be, for example, a mesh screen formed of metal or plastic. However, it is contemplated that the particulate filter 205 may be located in the fluid management system 16 between the vacuum source 18 and a vacuum receiving component of the biopsy probe assembly 14.
    [0046] The vacuum monitoring mechanism 30 is coupled to the vacuum source 18 to close the vacuum source 18 when a perceived vacuum level has dropped below a threshold level. The vacuum monitoring mechanism 30 may include, for example, a vacuum monitoring and control program that runs on the
    Petition 870190089868, of 9/11/2019, p. 15/46
    13/35 controller 26 and a pressure sensor 301, coupled to controller 26 and in fluid communication with the first vacuum path 20 to detect a pressure in the first vacuum path 20. If, for example, the vacuum flow level in the first vacuum path 20 falls below a predetermined level, indicating a restriction in the fluid management system 16, controller 26 can respond by closing vacuum source 18, for example, by shutting down electric motor 183. Alternatively, controller 26 can monitor the current supplied to the electric motor 183 and if the current exceeds a predetermined amount, indicating a restriction in the fluid management system 16, the controller 26 can respond by turning off the vacuum source 18, for example, turning off the electric motor 183.
    [0047] The disposable biopsy probe set 14 is configured to release releasably to the trigger assembly 12. As used here, the term releasable fixation means a configuration that facilitates a temporary connection followed by selective separation involving a manipulation of the biopsy probe set disposable 14 with respect to the driver set 12, without the need for tools. [0048] The disposable biopsy probe assembly 14 includes a cover 141, which essentially serves as a frame, in which a transmission device 42, a biopsy probe 44, housing 57 and the second vacuum path 22, are mounted, the housing 57 is slidably coupled to the cover 141. The sliding coupling of the housing 57 to the cover 141 can be achieved, for example, by a U-rail and clamp configuration. The cover 141 serves as a sliding cover for close the elongated cavity 241 in the housing 24 of the drive assembly 12 to protect the internal structure of the drive assembly 12 when the biopsy probe assembly 14 is mounted on the drive assembly
    Petition 870190089868, of 9/11/2019, p. 16/46
    14/35
    12. The biopsy probe 44 is operably coupled to the transmission device 42 and the transmission device 42 is operably coupled to the electromechanical energy source 28 of the driver assembly 12 when the biopsy probe assembly 14 is mounted on the assembly trigger 12.
    [0049] In the modality shown, the transmission device 42 includes a first driven unit 421 and a second driven unit 422 that are operably coupled to various components of the biopsy probe 44. In addition, the first driven unit 421 is engaged in an actionable manner to the first drive 361 of the electric drive set 36 of the drive set 12. The second driven unit 422 is operably engaged to the second drive 362 of the electric drive set 36 of the drive set 12. The first driven drive 421 is slidably coupled to housing 57 and the second driven unit 422 is contained in housing 57. The sliding coupling of the first driven unit 421 (for example, a sliding element) can be achieved, for example, by placing the first unit driven 421 in a longitudinal sliding channel formed in the housing 57.
    [0050] In the modality shown (see, for example, Figures 1 to
    3), the biopsy probe 44 includes a sample basket 441 and a cutter cannula 442. Sample basket 441 has a sharp tip 443 to help pierce tissue and has a sample notch 444 in the form of a recessed region to receive a biopsy tissue sample. The sample basket 441 and a cutter cannula 442 are configured to be individually movable along a longitudinal axis 445.
    [0051] In operation, the cutter cannula 442 is driven linearly by the first driven unit 421 to traverse the notch
    Petition 870190089868, of 9/11/2019, p. 17/46
    15/35 of sample 444 from sample basket 441 along longitudinal axis 445. For example, the first driven unit 421 can be in the form of a linear slide that is actuably engaged with the first drive 361 of the driver assembly 12, which in turn drives the cutter cannula 442 along longitudinal axis 445 in a first direction 46, that is, in the direction of a proximal end of the driver assembly 12, to expose the sample notch 444 of the sample basket 441, and drives the cutting cannula 442 in a second direction 48 opposite the first direction 46 to separate the prolapsed tissue within the sample notch 444. In addition, the first driven unit 421 and the second driven unit 422 can be configured to operate in unison to advance both the sample basket 441 and the cutter cannula 442 in unison along a longitudinal axis 445 in a drilling operation to help insert the biopsy probe 44 in fibrous tissue.
    [0052] The second driven unit 422 may include a flexible toothed rack 50 and a gear train 52. The flexible toothed rack 50 is connected to the sample basket 441 and the gear train 52 is engaged with the teeth of the flexible toothed rack 50. In operation, the second drive 362 transfers rotary motion to the gear train 52 and, in turn, the gear train 52 engages the flexible toothed rack 50 to move the sample basket 441 linearly to transport the captured tissue in the sample slot 444 out of the patient's body. The flexible toothed rack 50 is received in a spiral unit 54 when retracting, thus allowing a substantial reduction in the total length of the biopsy device device 10, compared to a rigid capture system. Each tissue sample collected is transported out of the patient's body and is collected by the tissue sample retrieval mechanism 56, which takes the tissue sample from the patient.
    Petition 870190089868, of 9/11/2019, p. 18/46
    16/35 sample notch 444.
    [0053] In the present embodiment, the spiral unit 54 and the tissue sample recovery mechanism 56 are like an integral unit with housing 57 which is common to the spiral unit 54 and tissue sample recovery mechanism 56. The housing 57 is attached, for example, slidably coupled to cover 141 and contains gear train 52 connected to at least part of the flexible toothed rack 50 in engagement with gear train 52. The tissue sample retrieval mechanism 56 will be described in more detail below. As shown, for example, in Figures 2, 5A and 6 to 8, housing 57 has a distinct shape S1, as a combination of curved and flat surfaces with an overall height H1, length L1 and width W1, which, in combination, define a unique profile for accommodation 57.
    [0054] In the present embodiment, the second vacuum path 22, also sometimes referred to as a disposable vacuum path 22, has a first end 221 and a second end 222, and includes, for example, ducts 223, a second valve a path 224 and a fluid management tank 225. The first end 221 is configured for removable attachment to the distal end 202 of the first vacuum path 20 of the driver assembly 12. The second end 222 is coupled in fluid communication with the sample basket 441 and, more particularly, it is coupled in fluid communication to the sample notch 444 of the sample basket 441.
    [0055] Also with reference to Figure 4B, the first end 221 of the disposable vacuum path 22 includes a second vacuum sealing element 226. The first vacuum sealing element 206 of the driver assembly 12 comes into contact with the second vacuum seal 226 of the disposable biopsy probe assembly 14 in seal engagement when the
    Petition 870190089868, of 9/11/2019, p. 19/46
    17/35 disposable biopsy 14 is attached to the actuator assembly 12. The second vacuum sealing element 226 is a compliant annular element, for example, rubber, which surrounds a second passage 227 of the second vacuum path 22.
    [0056] The second one-way valve 224, configured and arranged to allow the flow of negative pressure fluid from the sample basket 441 towards the first end 221 of the second vacuum path 22, and to prevent redundantly (together) with the first one-way valve 204 of the drive assembly 12) any positive pressure fluid flow in one direction from the first end 221 of the second vacuum path 22 towards the sample basket 441. In other words, the second valve one-way valve 224 provides a second level of redundant protection by preventing any positive pressure from reaching sample slot 444 of sample basket 441. In the present embodiment, the second one-way valve 224 can be, for example, a nozzle valve for example, a non-return valve, which opens the nozzle part of the duck nozzle valve with a fluid flow and closes with a reverse flow. As shown, the second one-way valve 224 can be positioned inside the second vacuum sealing element 226 at the first end 221 of the second vacuum path 22.
    [0057] Also with reference to Figure 5A, the fluid management tank 225 is fluidly interposed in the second vacuum path 22 between the first end 221 and the second end 222. The fluid management tank 225 includes a body 58 and a filter arrangement 60 contained within the body 58 configured to prevent a flow of residual biopsy biological material, for example, blood and particulate matter, from the sample slot 444 of the sample basket 441 to the vacuum source 18 of the aciPetição set 870190089868, of 9/11/2019, p. 20/46
    18/35 onador 12.
    [0058] The body 58 of the fluid management tank 225 has a first port 581 and a second port 582, with the second vacuum path 22 continuing between the first port 581 and the second port 582. The second port 582 of the storage tank fluid management 225 is coupled to sample basket 441. Each of the second one-way valve 224 and the second vacuum sealing element 226 of the second vacuum path 22 is coupled to the first port 581 of the fluid management tank 225 and, in the present embodiment, it is mounted on an external surface of the body 58 of the fluid management tank 225.
    [0059] As shown in Figures 5A and 5B, the filter arrangement includes a plurality of fluid absorbing layers 62, individually identified as layers 621, 622, 623 and 624, arranged side by side with each fluid absorbing layer 621, 622, 623 and 624 being spaced from an adjacent fluid absorption layer, for example 621 from 622, 622 from 623, 623 from 624. Each fluid absorption layer 621, 622, 623 and 624 has a respective opening through them, 641, 642, 643, 644, where openings adjacent to openings 641, 642, 643, 644 of the plurality of fluid-absorbing layers 62 are displaced with respect to the next, for example, in at least one among X, Y and Z directions, to form a tortuous open fluid passage 66 through the plurality of fluid absorbing layers 62. Each fluid absorbing layer 621, 622, 623 and 624 can be, for example, a killer paper. blur.
    [0060] As shown in Figures 5A and 5C, the filter arrangement may additionally include a porous filter element 68 arranged to be fluidly in series with the plurality of fluid absorbing layers 62 along the second vacuum path 22 which defines second pass 227. The porous filter element 68 displays
    Petition 870190089868, of 9/11/2019, p. 21/46
    19/35 greater restriction to the flow of fluid since a greater number of pores 70 in the porous filter element 68 is clogged by residual biopsy biological material, such as blood and tissue particles. When a volume of the fluid flow through the fluid management tank 225 has been reduced to a predetermined level, the vacuum monitoring mechanism 30 senses the vacuum restriction and the controller 26 responds by closing the vacuum source 18.
    [0061] With reference to Figures 6 to 13, each tissue sample taken is transported out of the patient's body and is collected by the tissue sample recovery mechanism 56. In general, the tissue sample recovery mechanism 56 collects tissue samples that were taken by digging the tissue sample out of the sample slot 444 of the sample basket 441 of the biopsy probe 44.
    [0062] With reference to Figures 6 to 9, the biopsy probe 44 of the biopsy probe set 14 includes a biopsy cannula, for example, a cutter cannula 442, and sample basket 441 arranged coaxially around the longitudinal axis 445 Sample basket 441, which has sample notch 444, is movably arranged with respect to the biopsy cannula (cutter) 442 along longitudinal axis 445 from a tissue collection position 72, as shown in Figures 6 and 7, up to a tissue sample recovery region 74, as shown in Figures 6 to 8, by the electromechanical energy source 28 and second drive 362, as described in more detail above with respect to Figure 3. Also with reference to Figures 10 and 12, sample notch 444 is an elongated recessed region of sample basket 441, having a generally semicircular cross section and has a recessed floor 76, a pair of spaced elongated edges 78, 80 on opposite sides of the recessed floor 76, an actuator transition bevel 82 and a
    Petition 870190089868, of 9/11/2019, p. 22/46
    20/35 posterior transition chamfer 84. The trigger transition chamfer 82 and the posterior transition chamfer 84 are located at opposite ends of the elongated recessed region, that is, sample notch 444 [0063] In the present embodiment, the tissue sample recovery 56 includes a sample tank receptacle 86, a sample collection tank 88, an alternating mechanism 90 and a tank positioning mechanism 92. The sample collection tank 88 is configured for removable insertion into the sample tank receptacle 86.
    [0064] The sample tank receptacle 86, which can be integrally formed with housing 57, includes a hollow guide 87 for slidingly receiving the sample collection tank 88. Thus, the configuration of the sample tank receptacle 86 is such that the sample tank receptacle 86 allows bidirectional movement of the sample collection tank 88 in directions 89 (represented by the double-headed arrow) that are substantially perpendicular to the longitudinal axis 445. In addition, the configuration of the sample tank receptacle sample 86 is such that the sample tank receptacle 86 prohibits movement of the sample collection tank 88 in a direction 46 or 48 along longitudinal axis 445.
    [0065] The sample collection tank 88 defines a single collection cavity 94 (see Figure 9) configured to receive multiple tissue samples, such as the TS tissue sample. The sample collection tank 88 has, in the formation collection cavity 94, a base 96, a front wall 98, a rear wall 100, a pair of side walls 102, 104 and a removable cover 106. The sample collection tank Sample 88 also includes a tissue sample curette 108. Sample collection tank 88 is configured to collect a tissue sample directly from sample notch 444, depending on the basket
    Petition 870190089868, of 9/11/2019, p. 23/46
    21/35 of sample 441 moves along longitudinal axis 445 in the tissue sample recovery region 74. In this respect, the tissue sample curette 108 of the sample collection tank 88 is configured to engage the sample notch 444 sample basket 441.
    [0066] Tissue sample curette 108 is attached to and projects downwardly from base 96. Tissue sample curette 108 extends forward towards a front end 110 of sample collection tank 88 to finish at an edge 112. The tissue sample curette 108 has a tissue collection lumen 114 through which each TS tissue sample taken by the biopsy probe assembly 14 will pass. The tissue collection lumen 114 begins at an opening 116 located near edge 112 and extends to collection cavity 94. The tissue sample curette 108 has a ramp face 118 located adjacent to edge 112. In addition, the tissue sample curette 108 has a first boss 120 and a second boss 122 which are positioned on opposite sides of aperture 116.
    [0067] A rack gear 124 is positioned longitudinally (e.g., vertically) on the rear wall 100 of the sample collection tank 88 to engage the alternating mechanism 90.
    [0068] With reference to Figures 6 to 9, the alternating mechanism 90 is configured to assist in the assembly of the sample collection tank 88 in the sample tank receptacle 86, and to assist in the removal of the sample collection tank 88 a from the sample tank receptacle 86. The alternating mechanism 90 is mounted in the housing 57 and includes a rotating gear 126 and a spring 128. The rotating gear 126 has a rotational axis 130, for example, a shaft, which is fixed to or it is integrally formed with the housing 57. The spring 128 is coupled between the rotating gear 126 and the housing 57 and is eccentrically mounted on the rotating gear
    Petition 870190089868, of 9/11/2019, p. 24/46
    22/35
    126, that is, at a location offset from the axis of rotation 130. The rotary gear 126 is located for drive engagement with the rack gear 124 of the sampling tank 88, as the sampling tank 88 is received sliding through the sample tank receptacle 386.
    [0069] With reference to Figures 6 to 8, the alternating mechanism 90 is configured to define a break point 132, for example, at the 12 o'clock position in the orientation, as shown. Figure 6 shows an orientation of the alternating mechanism 90 when the sample collection tank 88 is not installed in the hollow guide 87 of the sample tank receptacle 86, where the spring 128 is positioned beyond the 12 o'clock position of the watch in a clockwise direction as shown, thus defining a housing position 133 for the toggle mechanism 90.
    [0070] Figure 7 shows an orientation of the alternating mechanism 90 when the sample collection tank 88 is installed (inserted) in the hollow guide 87 of the sample tank receptacle 86. As the sample collection tank 88 is inserted into the hollow guide 87 of the sample tank receptacle 86, the rack gear 124 of the sample collection tank 88 engages the rotating gear 126 and rotates the rotating gear 126 about the axis of rotation 130, in the counterclockwise direction in the orientation, as shown. When the spring 128 is moved beyond the break point 132, for example, the 12 o'clock position of the clock, in a counterclockwise direction, as the sample collection tank 88 is received, slidingly, by the receptacle of the sample tank. sample 86, spring 128 provides a tensioning force 134, for example, a downward pressure via rotating gear 126, to force the sample collection tank 88 downwards in the direction of longitudinal axis 445. Thus, the tensioning force 134 exerts downward pressure on the cole tank
    Petition 870190089868, of 9/11/2019, p. 25/46
    23/35 sample size 88 when spring 128 is moved past the 12 o'clock position clockwise in the orientation as shown in Figure 7 and the tensioning force 134 is maintained when sample collection tank 88 is installed in the sample tank receptacle 86.
    [0071] With reference to Figure 11 in conjunction with Figures 7 to
    9, the tank positioning mechanism 92 is configured to selectively move the sample collection tank 88 between an elevated position 136, shown in Figure 7 and a lowered position 138, shown in Figures 8 and 9.
    [0072] The tank positioning mechanism 92 is engaged in an actionable way by the electromechanical energy source 28 to selectively lower, together with the alternating mechanism 90, the sample collection tank 88 from the elevated position 136 until the lowered position 138 to position a part, ie tissue sample curette 108, of the sample collection tank 88, in sliding engagement with the sample notch 444 to facilitate the collection of a tissue sample, for example, sample of TS fabric, from the sample basket 441, as the sample basket 441 is moved in the tissue sample recovery region 74. In addition, the electromechanical energy source 28 is engaged, in an actionable way, to the tank positioning mechanism 92 and / or flexible toothed rack 50 to selectively raise the sample collection tank 88, against the tensioning force 134 exerted by the alternating mechanism 90 and the tensioning force 152 exerted a by the tank positioning mechanism 92, from the lowered position 138 to the raised position 136 to disengage the sample collection tank 88 from the sample slot 444 of the sample basket 441 before, and after, the tissue collection sample basket 441.
    [0073] More particularly, with reference to Figures 6 to 8 and 11,
    Petition 870190089868, of 9/11/2019, p. 26/46
    24/35 the tank positioning mechanism 92 includes a lifting element 140, a spring 142, a lever 144, a tongue element 146 and a tongue latch 148.
    [0074] With reference to Figures 7 and 8, the lifting element
    140 is positioned along longitudinal axis 445. The lifting element 140 has a ramp surface 150 positioned to engage the ramp face 118 of the sample collection tank 88. Spring 142 is positioned between the lifting element 140 and the housing 57 to exert tensioning force 152 on the lifting element 140 to force the ramp surface 150 in a direction away from the ramp face 118 of the sample collection tank 88.
    [0075] As shown in Figure 11, the lever 144 extends from the lifting element 140 in a direction 154 perpendicular to the longitudinal axis 445. The lever 144 has a distal end 156 configured to engage the electromechanical power source 28, which can be shaped like a 158 pin.
    [0076] The electromechanical power source 28 is operable to move the lifting element 140 along the longitudinal axis 445 in the direction 46 to raise the sample collection tank 88 away from the longitudinal axis 445 according to the ramp surface 150 of the element lift 140 slides along the ramp face 118 of the sample collection tank 88. Likewise, the electromechanical power source 28 is operable to move the lift element 140 along the longitudinal geometric axis 445 in an opposite direction 48 to direction 46 to lower the sample collection tank 88 towards the longitudinal axis 445 as the ramp surface 150 of the lifting element 140 slides along the ramp face 118 of the sample collection tank 88.
    [0077] As shown in Figure 11, the power source he
    Petition 870190089868, of 9/11/2019, p. 27/46
    25/35 tromechanical 28 includes a lifting drive 363 that has an electric motor 383 coupled to a movement transfer unit 403 (shown schematically in part by a line) that ends, generally, in gears 164 and 166. Gear 166 includes a slot 168 for engaging pin 158 of lever 144. Motion transfer unit 403 provides rotary motion to gear 164, which in turn gives rotary motion to gear 166. Motion transfer unit 403 may include one or more among a gear, a gear train, pulley and belt arrangement, etc., to effect at least a partial rotation of gear 164. However, gear 166 is only rotated in a partial revolution, in order to effect a translation linear motion of pin 158 of lever 144 and, in turn, a linear translation of the lifting element 140.
    [0078] The lowering of the sample collection tank 88 for tissue sample collection (recovery) is initiated by the electromechanical power source 28, in which the gear 166 of the lifting drive 363 of the electromechanical power source 28 is rotated in a direction to move the lever 144 and, in turn, the lifting element 140, in direction 48, to lower the sample collection tank 88. The tensioning force 152 exerted on the lifting element 140 helps to move the surface in ramp 150 in direction 48 away from the ramp face 118 of the sample collection tank 88. At this time, the first shoulder 120 and the second shoulder 122 of the tissue sample curette 108 are positioned for respective sliding engagement with the pair of edges spaced elongated 78, 80 from the elongated recessed region of sample notch 444 of sample basket 441 along longitudinal axis 445.
    [0079] More particularly, with reference to Figures 8 and 11, the translation of lever 144 and, in turn, of the lifting element
    Petition 870190089868, of 9/11/2019, p. 28/46
    26/35
    140 in direction 48 causes the sloping face of the slant face 118 of the sample collection tank 88 to slide down the sloping surface 150 of the lifting element 140 and tissue sample curette 108 with the edge 112 moved for the elongated recessed region of the sample slot 444 of the sample basket 441 towards the recessed floor 76. Also with reference to Figures 9 and 10, the continued transport of the sample slot 444 in the direction 46 by the electromechanical energy source 28 will cause the edge 112 of the tissue sample curette 108 to slide along the recessed floor 76 and along the sides, between the elongated edges 78, 80 of the sample notch 444, digging and removing the tissue sample TS and transporting the TS tissue sample through tissue collection lumen 114 to collection cavity 94 of sample collection tank 88 along path 170. The lugs 120, 122 of sample collection tank 88 are configured to run along the spaced upper elongated edges 78, 80 of the sample basket 441, ensuring that no tissue sample material is pushed out of the sample notch 444.
    [0080] The elevation of the sample collection tank 88 occurs near the conclusion of the tissue collection sequence. Near the conclusion of the tissue collection sequence, the additional movement of the sample notch 444 of the sample basket 441 in direction 46 by operation of the electromechanical energy source 28 and second drive 362, is transferred to raise the element 140 by a hitch. drive the sample basket 441 in direction 46 with a T-shaped stop 172 (see Figure 12) attached to the lifting element 140, causing the lifting element 140 to move in direction 46. The curette edge 112 of the sample collection tank 88 reaches the sloped anterior transition chamfer 82 of sample notch 444 and is pushed up by the interaction between the ramp face 118 of the tank
    Petition 870190089868, of 9/11/2019, p. 29/46
    27/35 of sample collection 88 and the transition chamfer 82 of sample slot 444, thus starting to raise the sample collection tank 88. As the lifting element 140 is driven in direction 46 by the movement of the sample slot 444, the edge of the curette 112 leaves the sample notch 444 and the ramp face 118 of the sample collection tank 88 and comes to rest against the ramp surface 150 of the lifting element 140, which closes the sample collection fire. tissue 114 from the sample collection tank 88 and prevents the TS tissue sample from falling out of the tissue collection lumen 114.
    [0081] In addition, lift drive 363 is rotated to ensure that lift element 140 is fully shifted in direction 46 in case the force exerted by sample notch 444 is not sufficient to achieve translation. More particularly, the electromechanical power source 28 rotates the gear 166 of the lift drive 363 in one direction to move the lever 144 in the direction 46. Thus, the electromechanical power source 28 facilitates the movement of the lifting element 140 along the axis longitudinal 445 in the first direction 46 against the tensioning force 152 exerted by the spring 142 to raise the sample collection tank 88 as the ramp surface 150 of the lifting element 140 slides along the ramp face 118 of the sample collection tank 88.
    [0082] Upon completion of transporting the sample notch 444 in direction 46 towards the proximal end of the driver assembly 12, a beam spring tongue 174 of the T-shaped stop 172 (see Figure 12) removes residual tissue material and scraps from the second end 222 of the vacuum path 22 on the anterior transition chamfer 84 of the sample notch 444 to ensure that sufficient vacuum can be produced in the sample notch 444.
    [0083] Again with reference to Figures 6 to 8, 11 and 13, the
    Petition 870190089868, of 9/11/2019, p. 30/46
    28/35 tongue member 146 is attached to, or formed integrally with, lifting member 140. tongue member 146 extends from lever 144 in direction 46 and has a distal hook 176. tongue member 146 is located to engage with the tongue latch 148 to secure the tongue member 140 in a locked transport position, shown in Figure 13, corresponding to the elevated position 136 of the sample collection tank 88. The tongue latch 148 can be attached to or formed integrally with accommodation 57.
    [0084] One purpose of the tongue element 146 is to maintain the proper insertion position of lever 144 during transport of the biopsy probe assembly 14 to ensure proper insertion of the biopsy probe assembly 14 into the driver assembly 12. Before insertion of the biopsy probe set 14 on the trigger set
    12, lever 144 is held in a locked transport position, which is the only position that allows pin 158 at the distal end 156 of lever 144 to be inserted into slot 168 (for example, a driver recess) of the drive elevation 363 (see Figure 11). In the locked transport position, as shown in Figure
    13, lever 144 is held in position by the tongue element 146, which is held in tension against the tongue latch 148 by the pressure (tension force 152) of the spring 142. Thus, the insertion of the biopsy probe assembly 14 into the driver assembly 12 in the locked transport position results in displacement of pin 158 at the distal end 156 of lever 144 in slot 168 (e.g., a driver recess) of lift drive 363.
    [0085] A second purpose of the tongue element 146 is to prevent accidental reuse of the disposable probe. As part of the connection, lift drive 363 engages pin 158 at the distal end 156 of lever 144 and moves lever 144 in direction 46
    Petition 870190089868, of 9/11/2019, p. 31/46
    29/35 to a fully retracted position, which in turn causes the tongue element 146 to come out of engagement with the tongue latch 148. The tension of the tongue element 146 is released, causing the latch element 146 leaves the tongue latch plane 148 and prevents tongue member 146 from re-contacting tongue latch 148. Since spring 142 will force lift element 140 in direction 48, the locked transport position shown in Figure 13 can not be re-established once the biopsy probe set 14 has been removed from the trigger assembly 12. Since the locked transport position is the only position that allows the biopsy probe set 14 to be inserted into the trigger assembly 12, reuse accidental contact of the biopsy probe assembly 14 is prevented.
    [0086] With reference to Figures 14 and 15, the present invention provides a set of circuits to prolong the life of the battery 34 and, thus, help to prevent malfunction due to power failure.
    [0087] With reference to Figure 14, the biopsy trigger assembly 12 includes an electrical assembly 700. In the present exemplary embodiment, the electrical assembly 700 includes, but is not limited to, the previously described components of controller 26, the user interface 32 , the electric drive 361, the electric drive 362 and the electric drive 363. The electric set 700 is coupled to, for example, mounted on a substantial part of the biopsy driver housing 24. As previously described, each of the electric drives 361, 362 and 363 is configured to engage, in an actionable manner, corresponding driven units 421, 422 and the tank positioning mechanism 92, respectively, of the biopsy probe set 14.
    [0088] According to one aspect of the present invention, a control circuit 702 is coupled to, and is contained in, the housing of the
    Petition 870190089868, of 9/11/2019, p. 32/46
    30/35 biopsy trigger 24 of the biopsy trigger assembly 12. Control circuit 702 is electrically coupled to battery 34 and electrical assembly 700. Control circuit 702 includes a motion detector 704, a timing circuit 706, and a 708 battery stop circuit.
    [0089] Control circuit 702 is configured, using digital logic components and electrical energy, to conserve battery 34 by supplying electrical energy only to motion detector 704 after a predetermined time following a last detected physical movement of the trigger assembly biopsy 12. For example, in the present example, the control circuit can be configured to turn off the electrical power of electrical assembly 700 and timing circuit 706 after a predetermined time following the last detected physical movement of the biopsy trigger assembly 12 , while maintaining the electrical supply to the motion detector 704. In addition, control circuit 702 is configured to supply electrical power from battery 34 to all electrical components of biopsy trigger assembly 12, including electrical assembly 700, when a physical movement of the biopsy trigger assembly 12 is detected.
    [0090] Battery stop circuit 708 has a power input 710 electrically connected via power connection 711 to battery 34 and has a power output 712, electrically connected to controller 26, user interface 32 and electrical set 700 , for example, via the power bus 714. The motion detector 704 is electrically connected via the electrical power connection 716 to receive electricity from the battery stop circuit 708. The timing circuit 706 is electrically connected via the electrical power connection 718, to receive electrical energy from the battery stop circuit 708. Each of the electrical connections 711, 716 and 718
    Petition 870190089868, of 9/11/2019, p. 33/46
    31/35 and power bus 714, can be, for example, a wired connection, such as a printed circuit or wired cabling, and can include intervention components, such as switches and electronic components.
    [0091] The motion detector 704 is connected communicatively, via communication link 720, to the timing circuit 706. The motion detector 704 is connected communicatively, via communication link 722, to the battery stop circuit 708. The circuit Time delay 706 is communicatively connected via communication link 724 to battery stop circuit 708. Each communication link 720, 722 and 724 can, for example, be a wired connection, such as a printed circuit or wire cabling.
    [0092] The motion detector 704 is configured, for example, through electronic hardware, firmware and / or software, to provide a first signal via communication link 722, to the battery stop circuit 708 to make the circuit 708 battery stop enter an operating mode. In operating mode, electrical energy is supplied to electrical assembly 700 when the physical movement of the biopsy trigger assembly 12 is detected by motion detector 704.
    [0093] In addition, motion detector 704 is configured to provide a second signal via communication link 720 to timing circuit 706. The second signal provided by motion detector 704 to timing circuit 706 indicates the occurrence of the last physical movement detected from the biopsy trigger assembly 12 that was detected by the motion detector 704.
    [0094] The timing circuit 706 is configured, for example, through electronic hardware, firmware and / or software, to perform a timing function and to provide a third signal, via li
    Petition 870190089868, of 9/11/2019, p. 34/46
    32/35 communication link 724, to the battery stop circuit 708. More particularly, when the timing circuit 706 receives the second signal from the motion detector 704, the timing circuit begins to monitor the time since the last physical movement of the biopsy trigger assembly 12. When a predetermined time, for example, time limit, is reached, the timing circuit 706 provides the third signal to the battery stop circuit 708. The third signal provided by the timing circuit 706, does cause the 708 battery stop circuit to enter a battery stop mode. In battery stop mode, electrical power is supplied to motion detector 704 to exclude timing circuit 706 and electrical set 700, for example, only until motion detection 704. The third signal is supplied to the stop circuit of battery 708 after the predetermined time following the last detected physical movement of the biopsy trigger assembly 12.
    [0095] The length of the predetermined time measured by the timing circuit 706 can be selected, for example, as a time of sufficient duration to prevent constant cycling of the electrical assembly 700 between the on and off states, although being short enough to provide the desired reduction in battery power consumption 34. In the present mode, for example, the predetermined time is selected to be two minutes.
    [0096] According to another aspect of the invention, to avoid unnecessary energization of the motion detector 704, the timing circuit 706 and the electrical assembly 700, during transport / shipment of the biopsy trigger assembly 12, a probe presence circuit 726 is electrically coupled to the electrical power connection 716 between the battery stop circuit 708 and the motion detector 704. The probe presence circuit 726 is configured, for example, through electronic hardware, firmware and / or software,
    Petition 870190089868, of 9/11/2019, p. 35/46
    33/35 to detect a biopsy probe assembly 14 in the biopsy trigger assembly 12. More particularly, the probe presence circuit 726 is configured to disable, that is, not turn on, the motion detector 704 if the assembly biopsy probe assembly 14 is not mounted on the biopsy trigger assembly 12, such that neither the operating mode nor the battery stop mode will be operational if the biopsy probe assembly 14 is not mounted on the biopsy trigger assembly 12. In its In a simpler form, the probe presence circuit 726 can be a contact switch electronically interposed in the electrical power connection 716.
    [0097] However, it is contemplated that, at times, one may wish to check the functioning of the biopsy trigger assembly 12 without the biopsy probe assembly 14 being mounted on the biopsy trigger assembly 12. Therefore, as another aspect of the invention, a manual activation circuit 728 is electrically coupled to the electrical power connection 716 between the battery stop circuit 708 and the motion detector 704, for example, in parallel with the probe presence circuit 726.
    [0098] The manual activation circuit 728 is configured, for example, through electronic hardware, firmware and / or software, to bypass the presence circuit of probe 726 to activate (for example, activate) the motion detector 704 when the manual activation circuit 728 is actuated by a user to cause the battery stop circuit 708 to enter operating mode in the absence of the assembly of the biopsy probe set 14 on the biopsy trigger set 12. In its simplest form, the manual activation circuit 728 can be a switch electronically interposed in the electrical power connection 716, in parallel with the probe presence circuit 726.
    [0099] Figure 15 is a flow chart of a process to conserve
    Petition 870190089868, of 9/11/2019, p. 36/46
    34/35 var battery power according to the modality shown in Figure 14.
    [00100] In step S1000, it is determined whether the biopsy probe set 14 is installed in the biopsy trigger set 12, which is the function of the probe presence circuit 726.
    [00101] If the determination in step S1000 is NO, the process continues until step S1002, to determine if the manual activation circuit 728 has been activated. If the determination in step S1002 is NO, the process returns to step S1000. However, if the determination in step S1002 is YES, then the process proceeds to step S1004, in which the motion detector 704 is activated, that is, energized.
    [00102] Likewise, if the determination in step S1000 is YES, then the process proceeds to step S1004, in which the motion detector 704 is activated, that is, energized.
    [00103] In step S1006, it is determined whether the physical movement of the biopsy trigger set 12 is taking place, as detected by the motion detector 704. If the determination is YES, then in step S1008, the battery stop circuit 708 enters in operating mode, in which electrical power is supplied to the electrical assembly 700 and the process returns to step S1000, to continue monitoring. [00104] If, in step S1006, the determination is NO, then in step S1010, timing circuit 706 is actuated to monitor the time elapsed since the last physical movement of the biopsy trigger set 12.
    [00105] In step S1012, it is determined whether the predetermined time, for example, two minutes, has expired since the last physical movement of the biopsy trigger set 12.
    [00106] If the determination in step S1012 is NO, that is, that the predetermined time has not expired, then the process continues at eta
    Petition 870190089868, of 9/11/2019, p. 37/46
    35/35 pa S1006, for example, while in operating mode. [00107] If the determination in step S1012 is YES, that is, the predetermined time has expired, then, in step S1014, the battery stop circuit 708 enters the battery stop mode in which electrical power is only supplied to the detector motion 704, and where motion monitoring continues at step S1006, while remaining in battery stop mode.
    [00108] Thus, according to aspects of the present invention, the biopsy trigger assembly 12 can be assembled and operated in conjunction with the biopsy probe assembly 14 in extended sessions, while keeping energy consumption at a reasonable minimum to prolong battery life 34 and helps to prevent malfunction of the biopsy device 10 due to power failure.
    [00109] Although this invention has been described with respect to at least one modality, the present invention can be further modified within the spirit and scope of this report. Therefore, this application is intended to cover any variation, use or adaptation of the invention that uses its general principles. In addition, this application is intended to cover such departures from this report that are within the common or usual practice in the technique to which this invention belongs and which falls within the limits of the appended claims.
