    INSTRUMENT FOR MEASURING PARAMETERS ASSOCIATED WITH AN INCISION IN A FABRIC AND PROCEDURE FOR MEASURING PARAMETERS IN AN INCISION ON A FABRIC BY MEANS OF SUCH INSTRUMENT
    5 DESCRIPTION
    The present description refers to instruments for measuring parameters, such as, for example, forces and distances, associated with an incision in a tissue, such as a human or animal biological tissue. The present description also refers to methods 10 for measuring said parameters in an incision in a tissue by means of said instruments.
    STATE OF THE TECHNIQUE
    To be able to access quickly, safely, and with a large field of action within 15 the anatomical cavities of a human or animal being, incisions are made that cover all the anatomical planes. For example, in the case of wanting to access the abdominal cavity, a laparotomy is usually performed, that is, an incision in the abdominal wall. This procedure is performed at the beginning of any abdominal surgical intervention.
    twenty
    At the end of the procedure, the incision made on the abdominal wall should be closed by a suture that joins both edges of the incision. There are numerous techniques to join the edges of an incision depending on the type of suture material used as well as the manner in which the suture is performed. In any case, the technique that is carried out must close the incision with an adequate compression between both edges of the tissue to allow proper healing of the tissue.
    When the process of cicatrization of the closure of a laparotomy is not correct, a defect in the abdominal wall in the scar tissue called incisional hernia or eventration occurs. It is essential for the surgeon to carry out a correct technique during the closure of the abdominal wall despite the fact that there are some predisposing factors of the patient that are difficult to control and are out of reach. One of the most relevant risk factors to develop an event that can be controlled during
    Surgical intervention by the surgeon is the excessive tension in the suture with which the abdominal wall is closed.
    In this sense, the ideal tension at which an abdominal wall of a laparotomy should be closed is a parameter that is currently unknown and that corresponds to the tension necessary to compensate for the separation force of the tissue plus a minimal compression between edges. The closing force of a suture corresponds to the sum of the force necessary to approximate the edges plus the compression force between the edges of the tissue. Currently, during the closure of an abdominal incision, the surgeon does not know the force of separation in the incision that must be compensated. An excessive compression between edges causes a decrease in the irrigation of the same with the consequent bad healing, while a closure with little compression prevents a proper apposition of the aponeurotic edges and, consequently, again a bad scarring is obtained. Therefore, both situations are not desirable and it is necessary to obtain a balanced compression between edges to favor proper healing.
    There is, therefore, the need for intraoperative instruments and procedures that allow an objective and precise assessment of the suture's closing force during the closure of a laparotomy, instead of doing it in a subjective manner as 20 has been done in the actuality
    In this sense, there have been attempts in the art to determine parameters associated with tissues in an incision.
    For example, document EP0998877 proposes an apparatus comprising a clamp-like structure formed by two arms articulated by one end which are intended to be applied to a fabric. The apparatus includes a measuring element to determine the static force exerted on the arms and the distance between them.
    30 US2014276232 describes a skin tensiometer. It consists of two arms articulated by one end while its opposite ends are intended to be fixed on the skin. The tensiometer also includes a measuring element to determine the distance between the ends of the arms.
    Despite attempts in the art to determine parameters, such as forces or distances, in tissues where an incision has been made, there is currently a need for instruments that are capable of measuring such parameters so that the technician or surgeon can Obtain accurate information to determine the appropriate type of suture 5 to close each type of particular incision made in the tissue.
    DESCRIPTION OF THE INVENTION
    This instrument is of particular application in surgery, experimental surgery, 10 medical instruments, biomechanics, etc. to accurately measure parameters associated with an incision in a tissue. However, this instrument can be used in many other applications where it is necessary to perform dynamic measurements with precision.
    The instrument described comprises at least one pair of articulated arms between each other, which define a compass type structure in which the arms can rotate around a joint point, approaching or separating their ends. The arms are adapted to be anchored by their free ends on both sides separated from the tissue at points near the edges of the incision.
    20 To carry out the anchoring of the arms at the opposite edges of the tissue in the incision, at each of the free ends of the arms of the instrument there is at least one anchoring element, such as a barb, a needle, a clamp, or other similar element suitable to securely hold the free ends of the instrument arms in the tissue. When the instrument is anchored in the tissue through said anchoring element, the possibility of movement of the arms allows its ends to be approached so that the edges of the tissue in the incision approach each other until they come together. The anchoring element (s) can be mounted directly on the free ends of the arms or mounted on a detachable support that can be released releasably at the end of each arm.
    30
    In the embodiment in which each arm includes two or more anchoring elements at each end, said anchoring elements may be coupled to the support by one or more joints, so that the end of the arm receives the sum of the forces applied at each end. anchoring element and the values of these are distributed evenly
    thanks to the possibility of relative movement between the set of anchoring elements at the end of each arm.
    In the embodiment in which the anchoring elements are barbed, these preferably have rounded or blunt tips in order to prevent damage to the tissue when the arms are anchored therein and to be able to pull without tearing it.
    The anchoring elements are preferably coupled to the removable support separated from each other by a certain distance that may correspond to the distance or passage of the suture to be applied to the tissue in the incision. This separation distance can be the same in all arms or it can vary as required.
    The use of removable supports facilitates the sterilization of the anchoring elements, which is important since it is an element that is in contact with biological tissues. On the other hand, the feature of having a support with removable anchoring elements coupled to the end of each arm makes it possible to exchange supports with anchoring elements, such as spikes, for example, to easily adapt the number and type to the characteristics of the tissue and incision.
    20 Associated with the pair of arms is a measuring device that is adapted to perform dynamic measurements of at least one magnitude over time associated with said tissue in the incision. As used here, the term dynamic measurements refers to the determination, for example in real time, of multiple values of specific parameters, such as forces, distances, etc., associated with the tissue in the incision, which vary with time.
    It is envisioned that, in some embodiments of the present instrument, it may incorporate an appropriate arm locking mechanism. This locking mechanism would be adapted to keep the arms loosely locked in position, that is, capable of keeping the arms temporarily locked, preventing them from moving together, while the measurements are being made. Once the measurements have been completed, the arms could be unlocked so that they can move back together.
    However, in other embodiments, the present instrument may not incorporate any arm locking mechanism. In this case, the measuring device would be incorporated, for example, at the end of one of the arms.
    5 The locking mechanism can be any suitable mechanical mechanism arranged between the arms to block their mutual movement in various different angular positions. These various angular positions of the arms correspond to different distances between the edges of the tissue where an incision has been made. In a particular example, the arm locking mechanism may comprise an operable support 10 having a first part, for example in the form of a lever, associated with an arm of the pair of arms, and a second part or coupling part coupled to the Another arm of the pair of arms. The coupling part of the locking mechanism is adapted so that it can be released from the other arm by operating the lever-actuated support, which causes the mutual release of the arms so that they can be able to move again with respect to each other. In order to keep both arms coupled with respect to each other while dynamic measurements are being made, the coupling part of the operable support may have a toothed area adapted to engage in a corresponding toothed zone formed on a shoulder of the other arm. The teeth in both toothed areas act as a self-adjusting gear that ensures the blocking of the arms of the instrument in a certain position, ensuring the balance of forces and moments involved during the measurement at different distances of separation of the edges of the tissue in the incision, despite the force that is applied to the ends of the arms of the instrument due to the tendency that the edges of the tissue of the incision have to open or separate from each other.
    25
    One of the magnitudes that can be measured by the measuring device may be a force at the edges of the tissue in the incision or in the vicinity thereof. This force refers to the closing force of a suture, which is equal to the sum of the force necessary to approximate the edges and the compression force between the edges of the tissue. Therefore, the present instrument measures both defined traction force and transverse force necessary to maintain at a distance, or joined together, the edges of a human or animal tissue in which an incision has been made, as defined compression force as a transverse force applied to the edges of the tissue in the incision area.
    In order to measure this magnitude associated with the tissue in the incision, the measuring device may incorporate one or more suitable force sensors to measure said transverse forces at the edges of the tissue where the incision was made. The force sensor, or sensors, can be mounted, for example, on the first lever-actuated support part 5 mentioned above.
    Another of the magnitudes that the measuring device can measure can be a separation distance between the arms of the pair of arms. For this, the measuring device can incorporate one or more angular position sensors arranged (s) in the articulation between two arms.
    In one embodiment, the measuring device may be able to measure both forces and distances in a surgical incision in a human or animal tissue. This measurement of forces and distances in a surgical incision can be performed simultaneously if necessary. It is not ruled out, however, the measurement of parameters other than or derived from them, through this instrument.
    In any case, the measuring device may be capable of emitting a signal that is conveniently processed by an electronic device, such as, for example, a remote device. This signal, together with other parameters, such as the geometry of the instrument and the type of tissue (it should be taken into account, for example, that the edges of a superficial surgical wound are formed by skin with certain biomechanical characteristics, while the edges of a deep surgical wound that includes muscle and aponeurosis have other biomechanical characteristics associated with the contractile property of the tissue 25) is part of information that is provided to the operator or surgeon and that characterizes the suture to be used to close the incision, for example in terms of suture type, suture technique to practice, etc.
    The present instrument may also comprise devices for recording multiple dynamic measurements of magnitude, be it forces, distances, etc., made by the measuring device. These recording devices can be incorporated, for example, in the electronic equipment mentioned above.
    In one example, the present measuring instrument could be configured by coupling two or more pairs of arms articulated with each other. In this configuration, a pair of arms would be arranged in parallel with a pair of adjacent arms. In said configuration, the resulting instrument would incorporate corresponding measuring devices associated with the pairs of arms adapted to perform multiple dynamic measurements of forces, distances, etc., along at least a part of the incision in a human tissue or animal. The instruments could be coupled to each other coinciding with their axis of articulation but with a free rotation movement with respect to each other.
    10 To perform dynamic measurements of parameters in an incision in a tissue using the instrument described above, a technician such as a surgeon performs the following procedure.
    First, the surgeon places the instrument described above by anchoring each arm of the instrument at its free end respectively at opposite edges of the tissue near an area where an incision has been made through corresponding anchoring elements. For this, the surgeon may have previously defined in the tissue a series of anchoring holes to insert the anchoring elements of the arms of the instrument in order to properly anchor it in the tissue. Then, the surgeon blocks the arms from each other by means of the locking mechanism described above and, while the arms are locked, multiple dynamic measurements of at least one magnitude, such as traction forces and compression, distance of separation of the arms, etc. over time associated with said tissue in the incision.
    25
    With an instrument like the one described, the technician can previously measure the closing force of an incision before suturing it from the tensile and compressive forces read by the measuring device associated with the separation of the arms, which corresponds to the distance between the edges of a living or dead soft biological tissue in different anatomical planes 30 where an incision has been made. Through these multiple dynamic measurements, the technician can characterize the type of suture to be used to close the incision, such as its caliber, material, technique to be used, as well as whether to use a prosthetic reinforcement (mesh) or not.
    It has been found that, with a measuring instrument such as the one described, it is possible to measure with great efficiency and high precision the tension that the technician should apply to the suture, for example, during the closure of a laparotomy, the tension of closure of the edges of a surgical wound, the force of separation and the distance between the edges of the 5 tissues, the force of traction and compression at the edges of a surgical wound to determine the type of suture to be used in terms of caliber, type of material, technique, the need to use a prosthetic reinforcement (mesh), etc.
    Other objectives, advantages and characteristics of embodiments of the present measuring instrument will be clear to the person skilled in the art from the description, or will be derived when the description is put into practice.
    BRIEF DESCRIPTION OF THE DRAWINGS
    15 A non-limiting example embodiment will be described below, with reference
    to the attached drawing, in which:
    Figure 1 is an elevation view schematically showing an example of the present instrument for measuring forces and distances in an incision in a tissue; and 20 Figure 2 is a partial elevational view according to Figure 1 showing in detail an embodiment of the anchoring elements.
    DETAILED DESCRIPTION OF EMBODIMENTS
    The measuring instrument of the non-limiting example shown in the figure has been jointly designated by reference 100. The instrument 100 is intended to accurately perform dynamic measurements of forces F and distances D in an incision I in a human T-tissue. or animal so that a surgeon can determine the type of suture that has to be applied to close the incision I in the T tissue.
    30
    The instrument 100 shown in Figure 1 comprises a first arm 200 and a second arm 300. Both arms 200, 300 of the instrument 100 are articulated with each other at a point of mutual articulation 320. Said arms 200, 300 thus form a structure Compass type, as can be seen in the figure.
    In the respective free ends 205, 305 of the arms 200, 300 there are mounted removable supports 450 that include corresponding anchoring elements, in this example formed by handles 400, although they could be a needle, a clamp, or other similar element 5. Figure 2 shows in detail the example of the anchorage elements formed
    by puas. 400. The handles 400 are adapted to be anchored in anchor holes 700 that have previously been formed at opposite edges T1, T2 of the tissue T, close to an area where the incision I has been made, as shown in Figure 1 To prevent damage to the T fabric, for example to prevent tearing, the handles 400 have their rounded ends, as shown in Figure 2. The handles 400 of the end 205, 305 thus allow the arms to be anchored 200, 300 of the instrument 100 to the T tissue in which a surgical incision I has previously been made.
    The instrument 100 illustrated by way of example in Figure 1 also includes a measuring device 500. The measuring device 500 is intended to be made
    Dynamic measurements of forces F and distances D over time associated with tissue T. The measuring device 500 thus allows to measure parameters associated with tissue T in said incision I (forces F and distances D) that vary over time during which is being measured through instrument 100.
    twenty
    The measuring device 500 of the instrument 100 comprises an angular position sensor 560 arranged next to the joint 320 between the arms 200, 300 and a force sensor 570 disposed in a first part 625 of an operable support 620 associated with the first arm 200, which will be described later.
    25
    The angular position sensor 560 is adapted to measure a distance D of separation between the first arm 200 and the second arm 300. The distance D of separation between the first arm 200 and the second arm 300, defined in Figure 1 as the distance between the free ends 205, 305 of the arms 200, 300, it is proportional to the distance of separation of the edges T1, T2 of the tissue T in the incision I.
    The force sensor 570 is adapted to measure transverse forces F at, or in the vicinity of, the edges T1, T2 of the tissue T in which an incision I has been made. Such transverse forces F tend to maintain the edges T1, T2 of said tissue T to a
    certain distance or joined between sl These forces F can be both compression and traction. The transverse forces F are measured indirectly, that is, the force sensor 570 normally receives a force value at each end 205, 305 of the arms 200, 300 that is proportional to the actual value of the sum of forces in the area of the edges 5 T1, T2 of tissue T. The reading of said force values F can then be corrected
    suitably by an appropriate proportionality factor, for example, through a remote electronic equipment (not shown in the figure). The measurement of the transverse forces F could also be carried out directly.
    10 Both the angular position sensor 560 and the force sensor 570 of the measuring device 500 can work simultaneously if necessary. Both sensors 560, 570 allow a signal to be emitted, while performing dynamic parameter measurements on the T tissue, which is conveniently processed by said remote electronic equipment. This signal is processed as information that, together with other parameters such as the geometry of the instrument 100 and the type of tissue T, is provided to the technician. This
    Information properly characterizes the suture, such as the type of suture, the suture technique to be practiced, etc. for closing the incision I.
    Since to perform the aforementioned dynamic measurements of forces F and distances D over time associated with the tissue T it is necessary that the arms 200, 300 of the instrument 100 are locked so that they cannot move with each other, the instrument 100 incorporates a locking mechanism 600.
    In the non-limiting example shown in FIG. 1, the locking mechanism 600 consists of a toothed brace 350 which is fixed to the second arm 300 of the instrument 100 through anchor points 355. The teeth of the brace 350 engage with about teeth formed in a coupling part 630 of the operable support 620 mentioned above. The coupling part 630 of the operable support 620 is described below.
    30
    The operable support 620 has a first part 625 rotatably coupled to the first arm 200. The first part 625 is configured as a lever adapted to be operated by the operator or surgeon exerting a force in the direction represented by the arrow A in the figure. The actionable support 620 also has a second part or
    coupling part 630, which has been mentioned above, coupled to the first part 625 through a corresponding anchor point 635. This coupling part 630 of the operable support 620 is provided with teeth adapted to engage the teeth of said brace 350 of the second arm 300.
    5
    When the technician, such as a surgeon, exerts a force on the end of the first part 625 of the actionable support 620 in the direction of the arrow A, said first part 625 is rotated around the pivot point 626 clockwise, against the action of a spring 640, causing the coupling part 630 to rotate counterclockwise so that its coupling element descends downwards in the figure. As a result, the teeth of the coupling element of the coupling part 630 of the operable support 620 are disengaged from the teeth of the tie rod 350 of the second arm 300, thereby releasing the arms 200, 300 so that they can move back together. .
    fifteen
    The spring 640 cited above is arranged with one end fixed to the first part 625 of the operable support 620 and with the opposite end fixed to the first arm 200. Thus, the spring 640 acts to maintain the coupling between the teeth of the rod 350 of the second arm 300 and the teeth of the coupling part 630 of the operable support 20 620, preventing the arms 200, 300 from moving together while the
    dynamic measurements.
    With the locking mechanism 600, once the arms 200, 300 of the instrument 100 are locked in a certain position, the balance of forces and moments of the mechanism is ensured, despite the force that, due to the tendency of the incision to open, is applied at the ends 205, 305 of the arms 200, 300 of the instrument 100.
    As can be seen in detail in Figure 2 of the drawings, on each free end 205, 305 of the arms 200, 300 an interchangeable removable support 450 is arranged. This detachable support 450 incorporates anchoring elements which, in the example shown, comprise two prongs 400 that are separated from each other by a distance d in accordance with the passage of the suture to be applied to the tissue T in the incision I, which corresponds to the distance between two anchoring holes 700 adjacent to the edges T1, T2 of tissue T. This distance d between the handles 400 may always be the same or vary between arms 200, 300 according to
    the needs. The handles 400 are mounted on each support 450 so that they can move with respect to this with the possibility of rotation in a range of movement of up to 360 °. With this, the surgeon can adapt the number and type of barbs 400 to the characteristics of the T tissue where the incision I is formed.
    5
    To measure the forces and distances with the instrument 100 described, the surgeon initially marks on the T-tissue the length that will define the surgical incision I to practice. On both sides of the line that will define said incision I, a series of points are marked at a constant transverse distance d of said line and longitudinally equidistant from each other. 10 Subsequently, the incision I is made in the T tissue, after which the surgical intervention for which the incision has been necessary can be carried out.
    Once the surgical intervention has been completed, the previously marked points define corresponding determined positions that can be used to practice about 15 anchor holes 700 to insert the prongs 400 of the measuring instrument 100. It is preferable that the longitudinal distance d between said marked points substantially corresponds to the distance between each pair of barbs 400 of the instrument 100.
    Subsequently, the surgeon blocks the arms 200, 300 from each other through the locking mechanism 600 described above, so that the arms 200, 300 are kept apart from each other, without the possibility of movement, a transverse distance D according to the position of the edges T1, T2 of the tissue T in the incision I. With the arms 200, 300 locked together, and through the sensors 560, 570 of the measuring device 500, multiple dynamic measurements of the forces F are made and of the transverse distances 25 of the incision I which vary throughout the time during which the arms 200, 300 of the instrument 100 are locked together.
    With the traction and compression force values F at, or in the vicinity of, the edges T1, T2 of the tissue T in the incision I made in a tissue and the distances D of 30 separation of the arms 200, 300 of the instrument 100 , and considering the characteristics of the type of T tissue, such as the thickness where the incision I was made, the surgeon obtains information, as described above, about the type of suture to be used to close said incision I in terms of caliber, type of material, technique to use, use of prosthetic reinforcements (meshes), etc.
    Once the measurements have been made in the T tissue that allow characterizing the suture to be used in the closure of the incision I, the surgeon removes the instrument 100 by unlocking the prongs 400 of the edges T1, T2 of the T tissue and proceeds to close the incision I by means of the suture that has been determined based on the information obtained by the instrument 100. To perform the suture, the operator or surgeon can use the anchoring holes 700 that have been previously made at the edges T1, T2 of the T-tissue. .
    Although only some particular embodiments and examples have been described herein, the person skilled in the art will understand that other alternative embodiments and / or uses of the present measuring instrument are possible, as well as obvious modifications and equivalent elements.
    For example, although the present instrument has been described formed by at least 15 pairs of arms articulated with each other, defining a compass type structure, the arms of the instrument, alternatively, could be connected to each other in a mobile way from another proper way. For example, the arms could be linked together so that they can slide together.
    On the other hand, although the present instrument adapted to perform dynamic measurements of at least one magnitude over time has been described, for example determining multiple values of forces, distances, etc. of specific parameters (for example, in real time) that vary with time, the present instrument could also perform dynamic measurements, that is, it could determine particular values of 25 specific parameters at a given moment of time, without measuring or recording such
    Parameters during a specific time interval.
    The present description covers all possible combinations of the specific embodiments that have been described. The numerical signs relating to the drawings and placed between parentheses in a claim are only to attempt to increase the understanding of the claim, and should not be construed as limiting the scope of the protection of the claim. The scope of the present description should not be limited to specific embodiments, but should be determined only by an appropriate reading of the appended claims.
