    DEVICE FOR CROSSING THE PEN OF THE UTERUS OF A PENSION ANIMAL FOR THE TRANSFER OF MATERIAL OR SUBSTANCE FOR REPRODUCTIVE, THERAPEUTIC OR DIAGNOSTIC PURPOSES OR SAMPLING FROM UTERUS
    The present invention addresses the general problem of access, in vivo, to the uterus of a farm animal, for the purpose of atraumatic transfer of material or substance for reproductive, therapeutic or diagnostic purposes, or a specimen from the uterus, and in particular on a device allowing such access by the vaginal route.
    By the term "reproductive material or substance" (or reproduction) is meant semen or an embryo, the transfer device in question being then an artificial insemination device or an embryo transfer device. The reproduction material may be contained in a straw, as is well known.
    The expression "material or substance for therapeutic purposes" denotes any agent intended to move the subject from a pathological state to a normal state, or to prevent a pathological state. One can thus mention, as an example, deep intrauterine antibiotics, antiseptic solutions or isotonic washing solutions.
    By the term "diagnostic material or substance" is meant any agent enabling or assisting a practitioner to establish a diagnosis. As an example, mention may be made of labeling substances, such as methylene blue.
    The term "uterine sampling" refers to any removal of material or substance from the uterus, in order to perform analyzes such as cytology, a biopsy, etc.
    The present invention is applicable to livestock, in particular cattle, goats, and more generally to ungulates.
    Using cattle as an example, in order to access the uterus of a cattle for the transfer of material or substance for reproductive, therapeutic or diagnostic purposes, or for collection from the uterus it is currently generally known to go through the transrectal route.
    This method, illustrated in Figures la to the, consists, for an operator, to pass one of his arms in the rect bovine Re, in order to perform a catheterization of the cervix, the catheterization consisting in grasping the Cu uterine cervix and uterine horns, and align the cervix Cu with a T-catheter transfer or sampling held by the operator in his other hand, catheter T being first inserted in the vagina V, then in the cervix Cu so that the distal end of the latter is in the uterus U of the animal.
    The vagina V includes indeed, at its anterior part, many folds that must be crossed to reach the cervix Cu. The cervix or cervix consists of a central canal called the cervical canal which is usually composed of three cervical rings A that need to be aligned with one another so that the transfer or collection catheter T can be inserted into the uterus U cattle.
    This method, however, has several disadvantages.
    It is complex and difficult to perform because it requires the operator to manipulate the catheter while having one of his arms inside the rectum of the animal. Thus, it can be difficult for the operator to both manipulate the internal organs of the animal with one hand, and manipulate the other's catheter. The difficulty lies particularly in the fact of crossing the cervix by a manipulation to the blind, that is to say without viewing the organs of the animal, the operator relying solely on his sense of touch .
    By these complex manipulations, an inseminator performing a transrectal manipulation can suffer musculoskeletal disorders due in particular to injuries to the shoulders.
    This method also poses a risk of injury to the bovine, usually by laceration or transrectal perforation due to too abrupt manipulation of the genitals transrectally, or by deterioration of the walls of the vagina and / or uterus by the catheter. transfer or collection, which may in some cases lead to contamination by introduction into the uterus of substances from the vagina, and runs a risk of infection with cattle.
    Indeed, it is necessary, when using any material transfer device or substance for reproductive, therapeutic or diagnostic purposes, not to injure the animal. For example, in the case of artificial insemination, trauma associated with an injury will result in a local proinflammatory reaction that disrupts ovulation and then implantation of the embryo, which will limit the chances of successful fertilization. It should therefore be avoided that the device is likely, by its size and / or operation, to injure the animal. In other words, the device must be atraumatic.
    For the above reasons, the transrectal method requires some experience and is therefore currently generally carried out by specialized inseminators, and remains too complex to be carried out by the breeders themselves.
    The present invention aims to solve the problems encountered with the conventional transfer or sampling techniques described above by providing a device for accessing the uterus of a female animal vaginally, for the purpose of transferring material or substance to the uterus or a sample from the uterus, and to perform said transfer or withdrawal, the device preventing the transrectal passage, protecting the end of the transfer catheter or sampling, being atraumatic for the animal, and avoiding the creation of musculoskeletal trauma in the inseminator.
    The present invention therefore relates to a device for accessing the uterus of a female animal, in particular a bovine, vaginally, for the purpose of transferring material or substance for reproductive, therapeutic or diagnostic purposes, or a sample taken from the uterus, and to carry out said transfer or sampling, the device comprising a body assembly, secured to a gripper by an operator at its proximal end and having a distal end, a first passage passing through the device and opening at the proximal and distal ends, so as to establish a pathway between the interior and exterior of the animal, to allow the transfer of material or substance for reproductive, therapeutic or diagnostic purposes, or the removal, device being characterized by the fact that the whole body is substantially straight and rigid to allow its introduction into the vagina of the animal and that is provided for the distal end a cup whose opening is oriented opposite the proximal end of the body assembly, a central projection extending from the bottom of the cup and having a through hole, one end of which is communicating with the first through passage of the body assembly, the cup further having an orifice in communication with a distal end of a second through passage provided in the body assembly and the other end proximal thereof configured to be connected to suction means configured to create in the cup a depression to press the cup against the fornix of the animal, the first passage then forming a path to the uterus from outside the animal , the cup also comprising a second hole adapted to receive vision means having a field of vision oriented in the distal direction of the device to enable an operator to visualize the environment in front of the cup.
    The device according to the present invention thus makes it possible to create a passage for a transfer or sampling organ in the uterus of the animal, by allowing the operator to secure the cervix with the device in a manner that very easy thanks to the connection created between the cup and the fornix and through the means of vision. The orifice in communication the second through passage is preferably located in the bottom of the cup.
    According to a particular embodiment, the viewing means comprise a camera having a lens received in the second hole, a lighting source and means for transmitting the images captured by the camera to a display device having a screen enabling operator to observe said captured images.
    The camera may be an endoscopic camera integrating the light source, said transmission means being constituted by the body of the endoscopic camera, which body extends along the body assembly to the region of the proximal end of the latter, where the endoscopic camera is connected to the display device.
    In a variant, said transmission means consist of at least one electronic circuit received in the body assembly and connected to the camera, the at least one electronic circuit being configured to wirelessly transmit the images captured by the camera to the camera device. viewing. Advantageously, the cup may be transparent or translucent and comprise, on its rear part, light-emitting diodes arranged so as to illuminate in the distal direction of the device, the light beam of the diodes passing through the transparent cup and the diodes thus constituting the source of lighting for the camera.
    Preferably, the cup is removably connected to the body assembly. If he wishes, the operator can change the cup once the previous soiled. The operator may also choose not to change cups between animals, in which case health protection such as the shirt described below should be used.
    According to a particular embodiment, the body assembly is of cylindrical shape and comprises a body portion secured to the gripping means, the body portion being preferably formed of plastic material such as polyvinyl chloride. The orifice of the projection of the cup may be closed by a cap made of elastomeric material integral with the projection, the cap protecting the transfer or sampling member with respect to any secretions of the animal after removal of the plug, the cap having a central cross slot allowing a transfer or sampling member to pass therethrough when said member is pushed by an operator, and thus to exceed the projection.
    Thus, the transfer or sampling organ is more protected from vaginal secretions of cattle.
    The gripping means may comprise a handle and a body, the gripping means combined with the body assembly having a gun shape. The gun shape allows an easy grip of the device by an operator.
    The suction means may comprise a manual pump having a piston and a chamber, a part of the handle of the gripping means being pivotally mounted relative to the body of the gripping means and being connected to the piston, whereby a movement of the handle actuates the piston and creates a suction in the chamber.
    Thus, by operating the handle several times in succession, an operator can create a depression sufficient to press the cup against the cervix. In addition, the suction means being integrated in the device, it is not necessary to use additional suction means.
    Alternatively, the suction means may be separate from the device, and for example be formed by a vacuum pump operable manually or foot.
    According to a particular embodiment, the body assembly is of cylindrical shape, and comprises a fixed body portion of the gripping means and a head portion forming the distal end of said body assembly, the head portion being connected to the body portion by a pivot connection along a diameter of the body assembly, the device further comprising actuating means for orienting the head portion between a so-called right position in which the body assembly and the head portion are aligned on the same line, and a so-called inclined position in which the body assembly and the head portion form between them a non-zero angle, preferably between 0 ° and 35 °. The entrance to the cervix is usually not aligned with the vagina of the animal. In the prior art, the operator passed through the transrectal way to manipulate the organs and align them. In the case of the present device, an inclination of the distal portion avoids transrectal manipulation when the organs are not aligned.
    Preferably, the actuating means for orienting the head portion comprises a stirrup, a cable and a spring, the stirrup being pivotally mounted on and with respect to the gripping means, the cable connecting the stirrup and a first connecting point formed in the head portion, and the spring connecting the head portion and a second point formed in the body portion, the first and second points being located on either side of an imaginary plane including the pivotal connection and cutting the body portion lengthwise in two equal parts, such that the head portion is placed in an inclined position upon pivoting of the stirrup towards the proximal end of the device, by pulling on the cable, and returns to the upright position under the action of the spring when the caliper is released.
    Thus, the actuating means can be manipulated with one hand by the operator, said hand holding the device. The distal end of the cup may be selectively closed by a plug of elastomeric material, able to be secured to the cup by force insertion, the plug protecting the animal during insertion against the edges of the cup which can traumatize the animal, and protecting the interior of the cup with respect to possible secretions of the animal, the cap having on its outer face a through hole with which a wire is secured to the plug, the wire being of sufficient length to protrude outside the animal after insertion of the device into the vagina of the animal, and the wire allowing, by traction on the latter, to remove the cap when necessary, in order to free the passage for the transfer or sampling organ.
    The atraumatic feature is provided by the cap, because its shape, coupled with that of the cup and the rest of the device, allows insertion into the vagina without risking damaging the walls of the latter.
    The present invention also relates to a cup for a device as defined above.
    The cup may further comprise a sanitary jacket, substantially tubular and closed at its distal end, wound on itself at its proximal end, and disposed in a manner enveloping the cup and so as to be able to be unwound on the body assembly of a device as defined above, after the cup has been fixed on said device.
    To better illustrate the object of the present invention, will be described below, by way of indication and not limited to, particular embodiments with reference to the accompanying drawing.

    Referring to Figures 2 to 9, it can be seen that a device 1 for accessing the uterus of a female vaginal animal according to a particular embodiment of the present invention comprises a proximal body 2 and a distal portion 3 connected by a tubular body 4, the device 1 being generally pistol-shaped.
    The proximal body 2 comprises a hollow cylindrical portion 5 having, in its upper distal region, a projection 6 whose distal end is cylindrical and has a diameter slightly smaller than the internal diameter of the tubular body 4 so that said distal end is inserted into the tubular body 4 and secured thereto.
    The tubular body 4 is made of plastic, such as PVC (polyvinyl chloride).
    The proximal body 2 also comprises a handle 7 disposed diametrically opposite the projection 6, the handle 7 comprising a substantially straight fixed portion 8, a first end 8a of which is attached to the proximal end of the cylindrical portion 5 and extending radially therefrom.
    The handle 7 also comprises a mobile part 9 substantially straight, a first end 9a is pivotally mounted on the second end 8b of the fixed portion 8. The second end 9b of the movable portion 9 is secured to a first end 10a d ' a slider 10 substantially parallelepipedic and slidably mounted in the direction of its length in a groove 11 formed on the cylindrical body 5 and in the direction of the length thereof.
    Thus, the second end 10b of the slider 10 is located more proximally than said first end 10a of the slider 10. The second end 10b has a bend 12 having a straight portion 13 extending radially towards the axis of revolution of the cylindrical portion 5 at which it is secured to a piston 14.
    The piston 14 comprises a head 15 and a rod 16 secured to the head 15 and directed towards the proximal side of the device 1. Thus, the end of the right portion 13 is fixed to the proximal end of the rod 16.
    The piston 14 is disposed in the hollow internal part of the cylindrical part 5 of the proximal body 2, and the internal space delimited by the internal surface of the cylindrical part 5 and by the piston head 15 forms a chamber 17.
    A spring (not shown) extends between the second end 9b of the movable part 9 and the distal end of the groove 11, the spring allowing the moving part 9 to be returned to the initial position, as shown in FIG. that the second end 9b has been moved to the proximal side of the device 1, as shown in Figure 5.
    The chamber 17, at its distal end, is connected fluidically by a channel 18 to a reservoir 19 integral with the proximal body 2.
    A first end of a suction sheath 21 is connected to the distal portion 3, the sheath 21 passing inside the tubular body 4.
    The reservoir 19 has an outlet orifice 20 connected to a first branch of a quarter-turn valve 22 at T, the second branch of the T being connected to the other end of the sheath 21 and the third branch of the T being connected to an opening opening outwards.
    The valve 22 is operable between a first position, referred to as suction, in which the reservoir 19 and the sheath 21 are fluidly connected to each other and are not fluidly connected to the opening opening towards the outside, which allows exerting an aspiration at the first end of the sheath 21 during the actuation of the piston 14, and a second position, called venting, in which the reservoir 19, the sheath 21 and the orifice opening outwardly are connected fluidly, which allows to bring the first end of the sheath 21 to atmospheric pressure.
    The distal portion 3 comprises a proximal body portion 23 and a distal cup portion 24.
    The distal portion 3 may be made, for example, of transparent plastic material.
    The cup portion 24 is disposed with its open end facing the distal side of the device 1. The second end of the sheath 21 is in particular connected to an orifice 24a formed in the bottom of the cup portion 24 and opening outwards.
    The body portion 23 is cylindrical and hollow, and is connected to the tubular body 4 via a junction piece 25.
    The proximal end region of the connecting piece 25 is cylindrical, has a diameter slightly smaller than that of the tubular body 4 and is fixedly inserted thereto.
    Thus, the tubular body 4 extends between the projection 6 and the joining piece 25.
    The distal end region of the joining piece 25 is cylindrical, has a diameter slightly smaller than that of the body portion 23 and is surrounded by the latter.
    The body portion 23 and the connecting piece 25 are connected by a pivot connection 26 located on a diameter of the connecting piece 25, the link 26 being substantially horizontal when the handle 7 of the proximal body 2 is directed downwards.
    In addition, when the handle 7 of the proximal body 2 is directed downward, it can be seen in particular in Figure 10 that the body portion 23 surrounds the joining piece 25 only on the upper part thereof. A notch 23a is in fact formed on the body portion 23. This notch 23a allows the distal portion 3, when pivoted about the pivot connection 26, as shown in Figure 5, not to be blocked by the piece of junction 25 and to be thus freely inclined.
    The joining piece 25 comprises four orifices 25a, 25b, 25c, 25d. The sheath 21 passes through the orifice 25a, the elements passing through the other orifices will be detailed later in the description.
    A spring 27 connects the body portion 23 and the connecting piece 25 and is disposed on one side of an imaginary plane to which the axis of the pivot connection 26 and the longitudinal axis of the tubular body 4 belong.
    On the other side of said plane, a first end of a cable 28 is secured to the body portion 23 by means of a locking piece 29, integral with the cable 28. The locking piece 29 is mounted forcibly in a cavity (not shown) formed inside the body portion 23. The other end of the cable 28 is fixed in the upper part of a stirrup 30 enveloping the proximal body 2, and whose lower part is pivotally mounted on the outer walls of the portion of the proximal body 2 defining the groove 11.
    The cable 28 passes through an orifice 6a of the projection 6 of the proximal body 2, through the tubular body 4 and through the orifice 25b of the connecting piece 25.
    The device 1 also comprises a camera 31 of the endoscope type, with integrated lighting source, whose lens is flush with an orifice 24b formed in the bottom of the cup, and the other end is connected to means display (not shown), the camera passing through the orifice 25c of the junction piece 25, the tubular body 4 and an orifice 6b of the projection 6 of the proximal body 2, to be finally connected to a device of visualization D shown schematically, such as a monitor, a computer, an electronic tablet, a smartphone, etc. The orifice 25c is formed in the center of the joining piece 25.
    The cup portion 24 also includes a protrusion 32, formed in the center of the bottom of the cup portion 24 and directed toward the distal side thereof, a through hole 33 extending from one end to the other of the protrusion 32 and opening on the outside at the top of the latter.
    The through hole 33 is aligned with the hole 25d of the junction piece 25, the hole 25d being formed on the same side of the imaginary plane intersecting the piece 25 as the spring 27, and is located on the diameter perpendicular to the axis of the pivot connection 26.
    In other words, the orifice 25d is just above the orifice 25c, when the gun is held with the handle 7 facing downwards.
    Thus, the axis of revolution of the cup portion 24 is slightly shifted upwardly relative to that of the body portion 23. The orifice 25d is also aligned with an orifice 6c of the projection 6, forming a rectilinear path for the passage of a transfer member or sampling, the use of which will be described later in the description.
    The through hole 33 is closed by a slotted cap 34. The cap 34 is elastomeric material, has an ogival shape and has a cross slot whose center corresponds to the top of the ogive. It makes it possible to avoid interactions between the transfer or sampling member and the outside when said member does not protrude through the through-hole 33.
    The cap 34 is able to pass said member through the slots.
    The device 1 also comprises a cap 35 of rubber-like material removably inserted in the cup portion 24. The stopper 35 comprises a hole 36 in which a thread 37 passes, the thread 37 making it possible, by traction on the latter, to dislodge the cap 35 of the cup portion 24.
    The plug 35 has a rounded shape at its distal end, and its diameter at the base is substantially identical to that of the cup portion 24.
    Thus, the assembly formed by the cap 35 and the cup portion 24 does not have an angular edge, and therefore does not present a risk of injury to the animal, and has a shape facilitating the passage of the device 1 through the folds from the vagina of the animal.
    As shown in Figures 10 and 11, in use, an operator places a transfer or sampling member 38 in the passage of the device 1 provided for this purpose, until the distal end of said member is located in the projection 32 of the cup 24, near the slit cap 34.
    The device 1 is then in the initial position, as shown in FIG. 11, with the distal portion 3 aligned with the tubular body 4, and the plug 35 being present. The operator then inserts the device 1 by its distal end into the vagina V of a female animal until the cap 35 comes into contact with the uterine cervix Cu of the animal.
    The plug 35 is then removed by the operator, pulling on the wire 38 that the operator will have taken care to pass along the device 1 to the outside.
    Once the cap 35 has been removed, the operator can then visualize the uterine cervix Cu via the camera 31, and align the protrusion 32 with the neck Cu.
    It is possible for the operator to tilt the distal portion 3, by actuating the stirrup 30, if the configuration of the organs of the cattle requires it.
    Thus, as can be seen in FIG. 4, when the upper part of the stirrup 30 is moved towards the proximal side of the device 1, traction is exerted on the cable 30, which has the effect of rotating the part distal 3 downward from its initial position, ie aligned with the tubular body 4. The operator can thus more easily align the projection 32 with the uterine cervix Cu.
    Once the cervix Cu and the projection 32 are generally aligned, the operator places the cup portion 24 against the fornix of the neck Cu, and actuates the handle 9 to move the piston 14 and create a depression in the room 17.
    This depression, when the quarter-turn valve 22 is in the first position, creates a suction of the cervix Cu in the cup portion 24, and thus allows to secure the cup portion 24 with the cervix Cu for facilitate the passage of the transfer member or sampling 38. The operator can in particular move the device 1 to align the rings A cervix Cu uterus.
    Once the cup portion 24 is made integral with the neck of the uterus Cu, it is no longer necessary to orient the distal portion 3 of the device 1. Thus, when the force acting on the stirrup 30 is released, the spring 27 exerts a force which returns the distal portion 3 to its initial position, and by pulling on the cable 28, also places the stirrup 30 in its initial position.
    During aspiration, secretions from the animal can be sucked by the device 1. These secretions pass through the suction port 24a and then through the suction duct 21 and the quarter-turn valve 22, and then drop by gravity in the recovery container 19. The channel 18 connecting the container 19 to the chamber 17 is located in the upper part of the container 19, so that the secretions can not go into the chamber 17, thus avoiding a poor performance of the suction.
    Maintaining aspiration allows an operator to manipulate the cervix with the device. Another advantage, secondary, is that it prevents vaginal secretions of the animal from entering the uterus U, thus avoiding contamination of the uterus U by bacteria that may be present in these substances. The operator then pushes the transfer and sampling member 38 to pass the cap 34, until the distal end of said organ is in the uterus. This position is shown in Figures 13a and 13b.
    It can be seen in particular in FIG. 13b that the bell shape of the cup portion 24 is designed to conform to the shape of the cervix Cu, which thus ensures the joining of the cup portion 24 and the cervix. the uterus Cu.
    Once the transfer or sampling operation has been carried out, the operator removes the transfer or sampling member from the device 1. It then actuates the quarter-turn valve 22 to place it in the second position, in which the reservoir 19 and the sheath 21 are then brought to atmospheric pressure, which makes it possible to separate the cup portion 24 from the neck of the uterus Cu, and thus to remove the device 1 from the bovine.
    The device 1 according to the present invention therefore allows a single operator, in particular the breeder, to access, in a simple manner, the uterus of a female animal vaginally, for the purpose of transferring material or substance for reproductive, therapeutic or diagnostic purposes, or a specimen from the uterus, and for performing the transfer or collection.
    Referring to Figures 14 to 16, it can be seen that there is shown a device 1 'according to a second embodiment of the present invention, which comprises substantially the same elements as the device 1 described below. above.

    The distal portion 3 'comprises a proximal body portion 23' and a distal cup portion 24 '.
    The cup portion 24 'is disposed with its open end facing the distal side of the device 1'. Said other end of the sheath 21 'is in particular connected to an orifice 24a' formed in the bottom of the cup portion 24 'and opening outwards.

Thus, the light provided by the LEDs allows the camera 31 'to capture images of the environment in front of the cup 24' for easier placement of the device 1 'against the fornix of the cervix of the animal's uterus and easier alignment of the cervical rings.
    The cup portion 24 'also includes a projection 32' formed in the center of the bottom of the cup 24 'and directed towards the distal side thereof, the projection 32' including a through hole 33 'closed by a slotted cap 34 in a similar manner to the first embodiment. As for the first embodiment, the axis of revolution of the cup portion 24 'is slightly shifted upwardly relative to that of the body portion 23'.
    Although not shown, the device 1 'may also comprise a plug similar to the plug 35, with an associated wire.
    The device 1 'according to the second embodiment is used in a similar manner to the device 1, with the difference that the suction is not obtained by a trigger mechanism, but by the operation of suction means separate (manual vacuum pump), and the fact that the device 1 'is equipped with electronics enabling it to wirelessly transmit the images recorded by the camera 31'.
    Finally, with reference to FIGS. 17a and 17b, it can be seen that there is shown a cup 24 enveloped by a sanitary cover CS, protecting it vis-à-vis the outside. The sanitary liner CS is disposed wound on the cup 24, as shown in FIG. 17a, and after the cup 24 has been fitted onto the body assembly 4, the sanitary liner CS is unwound on the body assembly 4, so to protect the distal portion of the device 1, as shown in Figure 17b. The sanitary cover CS can also be used with the cup 24 'according to the first embodiment.
    It is understood that the above embodiments of the present invention have been given for information and not limitation and that modifications may be made without departing from the scope of the present invention.
