Description

Title of the invention: Anchor holder, kit for fixing at least one suture thread and assembly method Technical field

[0001] The invention relates to an anchor holder for at least one suture thread in at least one biological tissue of a human or animal body. The biological tissue may be bone tissue or soft tissue such as a tendon or a ligament. More broadly, the present invention relates to the field of surgery and in particular orthopedic surgery. In particular, the device according to the invention makes it possible to bring together and fix at least two distinct tissues together; alternatively, it is also possible to bring together and fix at least two parts of the same soft tissue, for example two parts of a meniscus.

[0002] More particularly, the anchor which is stored in the anchor holder makes it possible to fix ligaments or tendons to a bone through a surgical operation of the shoulder, knee, hip, hand, foot, elbow, ankle or even the spine. The challenges of this type of surgery concern in particular the reliability of the fixation of the sutures, the reduction of the intervention time, but also the reduction of the invasive nature of the intervention. Behind these challenges, the main objective is to reduce the postoperative convalescence period and to lower the risks of complications linked to the use of an anchor to treat patients. For these purposes, practitioners currently favor arthroscopy techniques with which the invention is compatible. Prior art

[0003] There are a good number of suture thread fixation kits that address these issues of reliability, reduction of invasiveness and also reduction of operating time.

[0004] In general, such a fixation kit comprises an anchor, also called an implant, to which one or more suture threads can be attached. For example, an anchor can be equipped with two or three suture threads which are respectively secured to the anchor. The anchor can also carry a suture strip. Thus, in the remainder of this document the term suture thread refers without distinction to a strip or a suture thread.

[0005] In addition, a suture thread fixation kit also includes a guide called a "driver" in the jargon of those skilled in the art. This guide most often has a handle which is extended by a rod to the end of which the anchor is removably attached. In order to prevent the suture threads from becoming tangled in the patient's soft tissues while the anchor is screwed in arthroscopically, the guide The fixation may have a cannulated passage or a lateral groove to hold the suture threads against or in the fixation guide. Document EP 2 779 913 illustrates an example of this type of fixation kit comprising a cannulated guide.

[0006] In order to optimize the surgical procedure time, surgeons wish to limit the time spent mounting the anchor on the fixation guide. For this purpose, manufacturers currently provide a fixation kit in which each anchor is pre-mounted on a fixation guide.

[0007] In practice, the suture threads are assembled to the anchor then the anchor is mounted on the fixation guide and the suture threads can be wound on the handle of the fixation guide thus constituting the fixation kit. The assembly of the fixation kit is carried out in a clean room, once assembled the kit is packaged, the fixation kit and its packaging are then sterilized.

[0008] In this way, during a surgical intervention, practitioners open the packaging at the last moment during the intervention to maintain the sterility of the fixation kit. Providing the anchor pre-mounted on the fixation guide saves operating time, however, after the anchor has been inserted into the patient's bone tissue, the guide is systematically discarded and put into medical waste treatment. For example, a shoulder rotator cuff repair operation, which aims to repair the detached tendons of the shoulder, requires on average the use of four to six anchors and thus as many guides are discarded. Given that a surgeon can operate on between fifteen and twenty patients per week, this constitutes a considerable amount of waste.

[0009] The invention aims to overcome all of these drawbacks. Statement of the invention

[0010] The invention aims to provide a technical solution for repairing ligaments or tendons effectively while reducing medical waste associated with this type of operation.

[0011] To this end, the present invention relates to an anchor holder for at least one suture thread in a biological tissue, the anchor holder comprising: • an anchor equipped with an assembly head, the anchor being connected to the suture thread, • a housing comprises a housing in which the anchor is stored in a determined position, the housing comprises a first opening, the assembly head of the anchor being positioned coaxially with the first opening in order to insert into the housing an assembly end of a fixing guide, the assembly end of the guide being complementary to the assembly head of the anchor, • a reel that is configured to store and release the suture thread, the reel communicating with the housing to allow passage of the suture thread, and • at least one locking member which has, on the one hand, an activated state in which the exit of the anchor from the housing and the release of the suture thread are prevented, and on the other hand, a deactivated state in which the exit of the anchor from the housing and the release of the suture thread are permitted.

[0012] The anchor holder according to the invention makes it possible to provide practitioners with an anchor connected to suture thread and stored in a case; advantageously, the anchor is ready to be quickly assembled with a fixation guide. Indeed, the first opening of the housing allows a suitable fixation guide to fit onto the head of the anchor. The anchor holder according to the invention thus provides a solution for simply and quickly mounting the anchor on the fixation guide while also offering an easy management solution for releasing the suture thread. It is then possible to provide a pre-assembled anchor in the anchor holder of the invention and to use a reusable and sterilizable fixation guide. In this sense, the present invention contributes to reducing the medical waste produced during an orthopedic surgery procedure while maintaining speed of execution of the surgical procedure.

[0013] In embodiments, the reel may be rotatably mounted about an axis and include at least one toothed crown. This allows the suture thread to be stored and easily released during the procedure.

[0014] In embodiments, the locking member may comprise a stop which cooperates with the toothed crown in order to block the rotation of the reel.

[0015] In embodiments, the dispenser may include at least one circular groove around which the suture thread is wound.

[0016] In embodiments, the housing may pass through the casing between the first opening and a second opening opposite and coaxial with the first opening, the anchor being disposed near the second opening. It is thus possible to slide the rod of the fixing guide in the housing and thereby unwind the wire parallel to the rod of the fixing guide.

[0017] In embodiments, the locking member obstructs the second opening. This makes it possible to limit the risks of the anchor accidentally coming out of the housing.

[0018] In embodiments, the locking member may be detachable from the housing, in which configuration the locking member transitions to its deactivated state when detached from the housing. The detachability of the locking member allows for easy release of the anchor and suture.

[0019] In embodiments the anchor holder may comprise a keying device disposed in the housing at least at the level of the first opening in order to insert the assembly end of the fixing guide in a determined orientation to allow assembly with the head of the anchor. The keying device improves the assembly precision of the fixing guide and the anchor through the housing. The keying device also ensures the translation of the anchor holder on the rod of the fixing guide when the locking member is in the deactivated state. In particular, according to one embodiment, the rod of the fixing guide may comprise a longitudinal groove, the keying device then serves as a guide pad for the movement of the housing by sliding in the groove.

[0020] In embodiments, the keying device is constituted by an edge which extends longitudinally along the axis of the housing.

[0021] In embodiments, the housing is mounted to be movable in rotation relative to the housing, the housing is movable, on the one hand, between an open position in which the housing is radially spaced from the reel, and on the other hand, a closed position in which the housing is connected to the reel, when the housing is in the closed position, the locking members are in their activated state and when the housing is in the open position, the locking members are in their deactivated state. This embodiment makes it possible to carry a tissue anchor mounted on an interface in order to fix the suture threads using an impactor.

[0022] The present invention also relates to a kit for fixing at least one suture thread in a biological tissue, the fixing kit comprising an anchor holder according to the invention and a sterilizable and reusable fixing guide which comprises a handle extended by a rod ending in an assembly end configured to be assembled with the assembly head of the anchor which is stored in the housing of the anchor holder. The fixing kit provides a technical solution allowing the simple and rapid assembly of the anchor on the fixing guide. In this sense, the fixing kit also addresses the technical problem by reducing waste by using a reusable fixing guide.

[0023] In embodiments, the anchor holder may be movable in translation on the rod of the fixation guide while the housing slides on the rod. This allows the anchor to be precisely mounted on the fixation guide and the suture thread to be tensioned.

[0024] In embodiments, the fixation kit comprises holding means that are configured to hold the suture thread near the rod or against the rod.

[0025] In embodiments, the holding means comprises a groove that extends longitudinally on the fixation guide, the groove being configured to receive the suture thread when the anchor holder is moved towards the handle on the rod of the fixation guide.

[0026] The present invention uses a sterilizable and reusable fixation guide adapted for use with an anchor holder defined according to the present invention. For this purpose, the fixation guide is characterized in that it comprises a handle and a rod which extends longitudinally from the handle towards an assembly end, the assembly end being configured to be assembled to the assembly head of the anchor. The fixation guide may comprise holding means which are configured to hold the suture thread near the rod or against the rod. For example, the holding means may be formed by a groove which extends longitudinally at least between the assembly end of the rod and the handle.

[0027] The fixation guide is adapted to cooperate with the housing of the anchor holder insofar as the fixation guide is configured to receive the housing sliding on the rod from the assembly end towards the handle. In parallel, the holding means make it possible to hold the suture thread close to the rod or against the latter. This makes it possible to prevent the threads from coming into contact with soft tissues while the surgeon inserts the anchor into the bone tissue under arthroscopy. For example, the holding means may comprise a groove provided on the fixation guide which is configured to receive the suture thread which is released by the reel when the housing is moved on the rod.

[0028] The fixing guide is further configured to cooperate with the anchor holder of the invention in order to precisely, simply and quickly mount the anchor at its assembly end.

[0029] Furthermore, the invention relates to a method of assembling a fixation guide and an anchor equipped with at least one suture thread configured to be inserted into a biological tissue, the anchor and the suture thread being stored in an anchor holder which comprises: - a housing receiving the anchor in a determined position, - a reel which stores the suture thread and communicates with the housing in order to allow the passage of the suture thread from the reel to the housing, and - at least one locking member which prevents the release of the anchor and the suture thread in an activated state;

[0030] The fixing guide used in the assembly method is sterilizable and reusable, in particular, the fixing guide comprises a handle, a rod which extends longitudinally from the handle towards an assembly end.

[0031] The assembly method according to the invention comprises the following steps: - assembling the assembly end of the rod with the anchor, the assembly end of the rod of the sterilized fixing guide being inserted into the housing of the anchor holder, - deactivate the locking device to release the anchor and the suture thread, and - move the anchor holder on the rod towards the handle, the anchor holder sliding through the housing on the rod, so as to put the suture thread under tension between the assembly end of the fixation guide and the anchor holder sliding on the rod.

[0032] The assembly method also makes it possible to address the technical problem, in particular by using a sterilizable fixation guide and an anchor holder which makes it possible to mount the anchor on the fixation guide while managing the tensioning of the suture thread in a simple and rapid manner.

[0050] [Fig. 17] is a schematic representation of a flowchart illustrating a method of assembling an anchor on a fixing guide according to the invention. Description of the embodiments

[0051] With reference to Figures 1 to 8 and 10 to 16, the invention relates to an anchor holder 10 of at least one suture thread 12 in a biological tissue. The anchor holder 10 is applied in particular for the repair of soft tissues such as ligaments and tendons. It makes it possible to reinforce or reattach the insertions of these soft tissues in the bone tissue 50 of a patient.

[0052] According to one embodiment of the invention and as illustrated in Figures 1, 3 to 9, the anchor holder 10 is part of a fixing kit 20 which also comprises a fixing guide 30 which is also part of the invention.

[0053] In this regard, the anchor holder 10 comprises an anchor 11 which is connected to at least one suture thread 12. According to one embodiment, the anchor 11 can be connected alternately to a suture strip, a suture thread, two suture threads or even three suture threads. According to one embodiment, the suture thread 12 can comprise needles for ligating soft tissues. In practice, the surgeon chooses to use one or other of these anchors 11 depending on the operation he has to perform. In the example of figures 2, 7 and 8, the anchor 11 is connected to two suture threads 12 which are linked to the anchor 11 and extend in a back and forth manner. This is why we distinguish in these figures four filaments which actually correspond to two suture threads 12.

[0054] As is more particularly visible in [Fig. 2], the anchor 11 comprises a distal end 110 which is configured to be inserted at the bottom of a pre-drilling made in the bone tissue. For this purpose, the distal end 110 is extended by a cylindrical portion. In addition, the anchor 11 comprises a proximal end 111 which corresponds to the assembly head of the anchor 11. The proximal end 111 is referred to as “proximal” because it allows cooperation with the fixation guide 30. The proximal end 111 of the anchor 11 comprises a blind hole inside which are located means for attaching the suture thread 12. The attachment means may for example consist of an eyelet arranged in the blind hole of the anchor 11.

[0055] In addition, the blind hole has an opening whose cross-section has a determined shape, for example, as illustrated in [Fig. 2], said cross-section is hexagonal. However, the cross-section can take another geometric shape, for example a polygonal shape of the triangle, rectangle, trapezoid, pentagon, etc. It should be noted that the cross-section of the opening of the blind hole can be different from the cross-section of the cavity of the hole. For short, it can be said that the assembly head of the anchor 11 has a determined shape. As can be seen in FIGS. 2, 5 and 6, the proximal end 111 is extended by a threaded portion 112. The threaded portion 112 makes it possible, firstly, to screw the anchor 11 into the bone tissue 50 using the fixing guide 30, and secondly, to ensure that the anchor 11 is held in the bone tissue 50.

[0056] The anchor holder 10 also comprises a housing 13 which is configured to store the anchor 11 and the suture thread 12. The anchor holder 10 can also be considered as another implant holder, according to this name the anchor 11 corresponding to the implant.

[0057] In the example illustrated in Figures 1 to 8, the housing 13 is in two parts, a base 130 which includes a housing 14 for the anchor 11 and a receptacle 131 which supports a reel 15. Here, the receptacle 131 is cylindrical and overhangs the base 130 which is arranged in the lower part of the housing 13. Thus, the base 130 includes a lower face 132 which delimits the lower part of the housing 13 and an upper face 133 which joins with the receptacle 131 (see [Fig.2]). The upper face 133 is convex with respect to the lower face 132. The base 130 extends in a longitudinal direction along a longitudinal axis AA.

[0058] As illustrated in [Fig.2], the receptacle 131 extends radially about an axis that is perpendicular to the longitudinal axis AA. In this example, the receptacle 131 comprises a side wall 134 and a peripheral wall 135. The side wall 134 extends radially about the axis of the receptacle 131 and defines the bottom of the latter. which is configured to receive the reel 15. The peripheral wall 135 extends from the peripheral edge of the side wall 134 in order to define a cylinder around the axis of the receptacle 131. In the lower part of the receptacle 131, the peripheral wall 135 merges with the upper face 133 of the base 130. Finally, the width of the peripheral wall 135 defines the depth of the receptacle of the reel 15. Moreover, in order to receive the reel 15, the receptacle 131 comprises receiving means 136. Here, the receiving means 136 extend at the level of the axis of the receptacle 131. In the embodiment illustrated in FIGS. 1 to 8, the receiving means 136 are constituted by a rotation shaft. However, the receiving means 136 may take another form and be arranged differently within the receptacle 131.

[0059] In the example of Figures 1 to 8, the receptacle of the reel 15 is thus open on an opposite face of the side wall 134 which constitutes the bottom of the receptacle 131. However, alternatively the receptacle 131 can also comprise an openable cover in order to close the receptacle of the reel 15.

[0060] According to one embodiment, the housing 14 makes it possible to store the anchor 11 in a determined position. As illustrated in FIGS. 2 and 11, the housing 14 extends longitudinally along the longitudinal axis AA. For example, the housing 14 may be cylindrical in shape. In particular, the housing 14 may pass through the housing 13 between a first opening 140 and a second opening 141 (see [Fig. 11]). Here, the second opening 141 is opposite and coaxial with the first opening 140, the anchor 11 being arranged close to the second opening 141. The first opening 140 is arranged on a front face 137 of the housing 13 while the second opening 141 is arranged on a rear face 138 of the housing 13 (see in particular FIGS. 2, 4, 10 and 11).Thus, the housing 14 may be cylindrical and have a longitudinal cavity 143 which extends through the housing 13 along a longitudinal axis AA from the front face 137 to the rear face 138 of the housing 13.

[0061] The housing 13 also comprises two sides, on the one hand, a closed side corresponding to the side wall 134 of the receptacle 131 extended by the base 130, and on the other hand, an open side which is defined by the opening of the receptacle 131 and the base 130 which extends it. The open side makes it possible to easily extract the reel 15 from the receptacle 131. Alternatively, as indicated previously, the open side may comprise an openable cover.

[0062] In this example, the head of the anchor 11 is positioned coaxially with the first opening 140. This makes it possible to use the first opening 140 to insert an assembly end 300 of the fixing guide 30 into the housing 14. It should be noted that the assembly end 300 of the fixing guide 30 is configured to be assembled to the head of the anchor 11. In the example illustrated in [Fig. 11], the housing 14 comprises a receiving portion 144 which is proximal to the second opening 141. The receiving portion 144 has dimensions greater than the rest of the cavity 143 in order to receive the anchor 11. A shoulder 146 defines the demarcation between the receiving portion 144 and the rest of the cavity 143 which opens at the level of the first opening 140. The assembly head of the anchor 11 is placed in abutment with the shoulder 146 in order to be positioned to receive the assembly end 300 of the fixing guide 30.

[0063] As illustrated in Figures 1, 2, 6, 8 and 10, the anchor holder 10 comprises a keying device 145. The keying device 145 is arranged in the housing 14 at the first opening 140. The keying device 145 can also extend longitudinally through the housing 13. As can be seen in [Fig. 2], the keying device 145 extends parallel to the longitudinal axis AA along a median longitudinal plane LM of the housing 13. The keying device 145 makes it possible to insert the assembly end 300 of the fixing guide 30 in a determined orientation to allow assembly with the head of the anchor 11.

[0064] According to one embodiment, the keying device 145 is constituted by an edge which extends longitudinally and parallel to the axis AA of the housing 14. The edge projects inside the cavity of the housing 14.

[0065] As illustrated in Figures 1 to 4, the anchor holder 10 comprises at least one locking member 16 which makes it possible to hold the anchor 11 in the housing but also to avoid releasing the suture thread 12 which is stored in the reel 15. For this purpose, the locking member 16 has an activated state and a deactivated state.

[0066] Figures 1 and 3 show an anchor holder 10 in which the locking member 16 is in its activated state. In this state, the exit of the anchor 11 from the housing 13 and the release of the suture thread 12 are prevented. In practice, in its activated state the locking member 16 obstructs the second opening 141 of the housing 14.

[0067] Conversely, [Fig. 4] illustrates an anchor holder 10 in which the locking member 16 is in a deactivated state. In this state, the exit of the anchor 11 from the housing 13 and the release of the suture thread 12 are permitted. In the embodiment illustrated in FIGS. 1 to 11, the locking member 16 is detachable from the housing 13. As illustrated in [Fig. 4], the locking member 16 passes into its deactivated state when it is detached from the housing 13. In particular, the locking member 16 fits onto an assembly portion 1300 of the base 130 in the manner of a locking shoe. For this purpose, as illustrated in [Fig. 4], the locking member 16 comprises a lower wall 160, two side walls 161 and a rear wall 162. The lower wall 160 may be perforated to save material. A front opening 163 and an upper opening 164 give the locking member 16 a shoe shape.

[0068] The assembly portion 1300 extends from the rear face 138 to a portion front 1301 of the base 130. The front portion 1301 comprises on the front face 137 the first opening 140 of the housing 14.

[0069] Furthermore, the anchor holder 10 comprises means for fitting the locking member 16 onto the base 130. In this example, the fitting means comprise at least one rib 1302 which is arranged on the assembly portion 1300. As illustrated in FIGS. 4 and 5, the rib 1302 can extend longitudinally perpendicular to the axis AA. Here, the fitting means comprise two ribs 1302 parallel to each other and arranged on each side of the base 130. As can be seen in FIGS. 4 and 5, the fitting means may comprise lugs 1303. Each lug 1303 projects from a rib 1302. Here, a lug is arranged at each end of the rib 1302. A lower end which is proximal to the lower face 132 of the housing and a high end which is proximal to the receptacle 131.

[0070] In addition, the fitting means comprise at least one groove 165 complementary to the rib 1302 in order to allow the fitting and unfitting of the locking member 16 on the base 130. For this, each groove 165 is provided on a side wall 161 of the locking member 16. In particular, each groove 165 extends along a longitudinal axis perpendicular to the axis AA and each groove 165 is arranged on the side wall 161 so as to slide on a rib 1302. The lugs 1303 allow better cooperation between a groove 165 and a rib 1302.

[0071] Furthermore, the anchor holder 10 may comprise indicators to ensure the process of assembling the anchor 11 on the fixing guide 30. For example, the locking member 16 comprises an arrow 166 marked with the number 1. This arrow 166 is oriented downwards, it points to the lower face 132 of the housing 13. The arrow 166 is an indicator, it indicates to the practitioner that he must first pull the locking member 16 downwards in order to unlock the anchor 11 and the suture thread 12. The arrow 166 thus indicates how to move the locking member 16 from its activated state to its deactivated state. The assembly portion 1300 of the base 130 also carries an indicator of use of the anchor holder 10. Here again an arrow 1304 indicates to the practitioner in which direction the anchor holder 10 must be moved along the fixing guide 30 in order to unwind the suture thread 12. In this example, the arrow 1304 is marked with the number 2.This is because it corresponds to a step which follows the removal of the locking member 16 and which the surgeon must carry out to finish releasing the suture thread 12 from the reel 15.

[0072] As illustrated in Figures 2, 7 and 9, the anchor holder 10 comprises a reel 15 which is configured to store and release the suture thread 12. For this purpose, the reel 15 communicates with the housing 14 in order to allow the passage of the suture thread 12. For this, a passage 142 can be provided in the upper face 133 of the base 130. In this way, the receptacle 131 in which the reel 15 is stored communicates with the housing 14 in which the anchor 11 is stored. The passage 142 is visible in [Fig.2] in the section CC of [Fig. 10] which is illustrated in [Fig. 11].

[0073] In this example, the reel 15 is rotatably mounted around an axis. For this, the reel 15 is mounted on the rotation shaft of the receiving means 136 of the receptacle 131.

[0074] The reel 15 comprises at least one toothed crown 150, 151, 152. As can be seen in [Fig. 2] the reel 15 comprises three toothed crowns 150, 151, 152 which are parallel to each other. In particular, the reel 15 comprises two lateral toothed crowns 150, 151 and a central crown 152 which is arranged at an equal distance from each lateral toothed crown 150, 151. A first lateral toothed crown 150 comprises in its center an opening 153. This opening 153 is configured to receive the rotation shaft of the receptacle 131. In this sense, the opening 153 acts as a bearing to guide the rotation of the reel 15 around said rotation shaft. The second lateral toothed crown 151 also has an opening, however, as can be seen in [Fig.2], this opening has a diameter greater than that of the opening 153.

[0075] In one embodiment, the reel 15 comprises at least one circular groove 154 around which the suture thread 12 is wound. The suture thread 12 is not shown in the circular groove 154 in Figures 1 to 8 in order to simplify the representation of the invention. In the example of [Fig. 2], the reel 15 comprises two circular grooves 154. Each circular groove 154 is delimited on one side by a lateral toothed crown 150, 151 and the other side by the central toothed crown 152.

[0076] Furthermore, the reel 15 may comprise means for disengaging the receptacle 131, for example a withdrawal loop allowing an operator to exert traction on the reel 15 in a direction parallel to the axis of rotation in order to extract the reel 15 from the receptacle 131. The withdrawal loop is not illustrated in the drawings, it may be passed through two holes which are arranged on the lateral toothed crown 155 which is visible when the reel 15 is inserted into the receptacle 131. In this example, the reel 15 comprises at least one slot 156 in order to block the suture thread 12. Here, the slot 156 extends radially over a crown 150, 152. Here, the first lateral crown 150 and the central crown 152 respectively comprise a slot 156. The two slots 156 of the reel 15 are coaxial. When the suture thread 12 is completely unwound, it is sufficient to apply traction to the suture thread 12 to release it from the slot 156.

[0077] As can be seen in Figures 1 to 4, the locking member 16 comprises a stop 167. This stop 167 is arranged on the rear wall 162 of the locking member. rusting 16. The stop 167 is configured to cooperate with at least one toothed crown 150, 151, 152 in order to block the rotation of the reel 15. According to one embodiment, the stop 167 cooperates with the teeth 155 of each toothed crown 150, 151, 152 in order to block the rotation of the reel 15. For this, the stop 167 has a shape complementary to the shape of the teeth 155.

[0078] Furthermore, the receptacle 131 comprises a passage arranged on the rear face 138 of the housing 13 in order to allow the stop 167 to be inserted between two teeth 155 of at least one toothed crown 150, 151, 152 in order to block the rotation of the reel 15. In the example of FIGS. 1 and 4, the receptacle 131 comprises a slot 139 which is formed in the peripheral wall 135. The slot 139 allows the stop 167 to be inserted between the teeth 155 of at least one toothed crown 150, 151, 152. The rotation of the reel 15 is thus blocked as can be seen in particular in [Fig. 3]. Of course, when the locking member 16 passes into its deactivated state, the stop 167 is disengaged from the reel 15 and releases its rotation.

[0079] Figures 12 to 16 illustrate another embodiment of the anchor holder 10 of the invention in which the anchor 11 is a fabric anchor. In the jargon of those skilled in the art, this type of anchor may be called a "soft anchor". As illustrated in [Fig. 12], the fabric anchor 11 comprises two sheaths 113 which intersect. More precisely, the sheaths 113 intersect and are connected together at the distal end 110 of the anchor 11. At the distal end 110, the folding of the sheaths 113 at their crossing forms a structure which can be gripped by a fork-shaped pin. The fold corresponds to the assembly head 114 of the anchor 11. The distal end 110 is configured to be inserted into a pre-drilling made in bone tissue. At the proximal end 111 of the anchor 11, the sheaths 113 are opened so that a suture thread 12 passes within each sheath 113.

[0080] A tissue anchor 11 is inserted forcibly into the bone using an impactor, once past the cortical part of the bone which has a certain hardness, the tissue anchor 11 penetrates into the spongy part of the bone, under the effect of traction to remove the impactor, the tissue forms a ball of diameter greater than the drilling which prevents the extraction of the tissue anchor 11.

[0081] In this embodiment, the housing 13 also comprises a receptacle 131 which overhangs a base 130. The receptacle 131 is configured to accommodate a reel 15 and a passage 142 is provided between the receptacle 131 and the base 130 in order to allow the suture thread 12 to be stored in the reel 15 while being connected to the anchor 11 which is stored in the housing 14.

[0082] As illustrated in Figures 12, 14 and 15, the anchor holder 10 may comprise an interface 17 on which the fabric anchor 11 is mounted. The interface 17 is configured to ensure precise assembly of the assembly end 300 of the fixing guide 30 with the fabric anchor 11. For this, the interface 17 holds the fabric anchor 11 in a determined position for assembly with the fixing guide 30. For this purpose, the housing 14 comprises an annular passage 147 in which the interface 17 is positioned.

[0083] In this example, the interface 17 comprises a central body 170 extended, on a first side, by a connector 171, and on a second side, by an impacting support 172 which carries the tissue anchor 11 and is configured to impact the tissue anchor 11 into the bone.

[0084] The connector 171 which is configured to be assembled with the assembly end 300 of the fixing guide 30. Here, the connector 171 is threaded, according to this configuration, the assembly end 300 can be formed by a socket whose dimensions and thread are complementary to the connector 171. Nevertheless, the connector 171 can be produced by means of another mechanical connector of male or female type.

[0085] The connector 171 has a cross-section smaller than that of the central body 170. Thus, as can be seen in [Fig. 12], the junction between the connector 171 and the central body forms a shoulder. Thus, within the housing 14, the connector 171 has a section smaller than the opening of the annular passage 147 while the shoulder is placed in abutment against the annular passage 147. The cooperation between the interface 17 and the annular passage 147 contributes to maintaining the fabric anchor 11 in a determined position.

[0086] The impacting support 172 of the fabric anchor 11 here takes the form of a pin onto which the assembly head of the fabric anchor 11 is threaded while the two sheaths 113 are folded onto the pin. The end of the pin is placed against the intersection of the sheaths 113. The impacting support 172 also comprises a cross-section smaller than that of the central body 170. As illustrated in [Fig. 12], the central body 170 comprises a bevel at the junction with the impacting support 172.

[0087] In the embodiment of Figures 12 to 16, the anchor holder 10 comprises two locking members 18, 19 which are arranged at the junction between the base 130 and the receptacle 131. Here, the locking members 18, 19 are movable between an activated state and a deactivated state. In their activated state illustrated in [Fig. 13], the locking members 18, 19 block, on the one hand, the rotation of the reel 15, and on the other hand, the release of the fabric anchor 11.

[0088] In particular in this example, a first locking member 18 is integral with the base 130 and blocks the rotation of the reel 15 in the activated state. Here, the first locking member 18 is constituted by a tooth which cooperates with the toothing of at least one of the toothed crowns 150, 151, 152 of the reel 15. The tooth acts as a stop for the reel 15, it is visible in figures 12 to 14 and 16. In figures 14 and 16 the tooth is not engaged with a toothed crown 150, 151, 152 since the locking members 18, 19 are in the deactivated state.

[0089] In the embodiment illustrated in figures 12 and 14 to 16, the second locking member 19 is integral with the peripheral wall 135 of the receptacle 131. This is particularly visible in figures 15 and 16. In particular, the second locking member 19 is arranged at the junction between the base 130 and the receptacle 131 at the level of the housing 14.

[0090] Here, the second locking member 19 is constituted by two cheeks 190 parallel to each other. The cheeks 190 extend projectingly into the cavity of the housing 14, this is visible in figures 14 and 15. In this example, each cheek 190 has a curved internal surface 191 (see [Fig. 16]).

[0091] As can be seen in [Fig. 15], the spacing between the cheeks 190 is configured to allow the passage of the impacting support 172 of the fabric anchor 11 while preventing the passage of the central body 170. In particular, the domed internal surface 191 of each cheek 190 cooperates with the bevel located at the junction between the central body 170 and the impacting support 172, this to maintain the interface 17 in position within the housing 14.

[0092] As illustrated in Figures 14 and 16, the base 130 is mounted to be movable relative to the receptacle 131. In particular, the base 130 is mounted to be movable in rotation relative to the receptacle 131. For this, the base 130 can be articulated to the receptacle via a pivot connection 1305. On the one hand, the pivot connection 1305 can comprise two coaxial bearings 1306 arranged on two ears 1306 parallel to each other. The two lugs 1307 are respectively part of a side wall 134 of the base 130. The two lugs 1307 are arranged proximally of the front face 137 of the housing 13. Furthermore, the pivot connection 1305 comprises an axis which can be formed by two coaxial pins 1308 which are connected to the receptacle 131 and are arranged so as to engage in the bearings 1306 arranged on the base 131. In this example, the pins 1308 are arranged respectively on a cheek 1309 secured to the receptacle 131.The two cheeks 1309 are parallel to each other and located proximally to the front face 137 of the housing 13. Furthermore, the two cheeks 1309 are connected to each other by a wall which extends over the front face 137 of the housing 13 and in which the first opening 140 is formed.

[0093] The cooperation between the cheeks 1309 and the ears 1307 to form the articulation makes it possible to maintain a free space between the cheeks 1309 which corresponds to the cavity of the housing 14 which allows the passage of the interface 17 and the rod 301 of the fixing guide 30.

[0094] The base 130 is thus movable between an open position and a closed position. In the closed position, the base 130 is integral with the receptacle 131, conversely, in the open position, the rear part of the base 130 is radially distant from the receptacle 131 (see [Fig. 14]). In this embodiment, the closed position of the base 130 corresponds to the activated state of the locking members 18, 19. The open position of the base 130 corresponds to the deactivated state of the locking members 18, 19.

[0095] Figures 13 and 15 illustrate the anchor holder 10 while the base 130 is in the closed position and the locking members are in their activated state. For example, [Fig. 13] shows the tooth of the first locking member 18 which is engaged with the toothing of the reel 15, which blocks the rotation of the reel 15 and thereby the release of the suture thread 12.

[0096] In [Fig. 15], the base 130 is not shown so that the second locking member 19 is visible in its activated state. Here, the cheeks 190 enclose via their domed internal surface 191 the interface 17 at the level of the bevel forming a junction between the central body 170 and the impacting support 172. At the same time, the connector 171 is positioned in the housing 14 coaxially with the first opening 140. In this position, the cheeks 190 block the translation of the interface 17 and therefore the extraction of the fabric anchor 11 from the housing 14 through the second opening 141.

[0097] Figures 14 and 16 illustrate the base 130 in the open position. In the example of [Fig. 14], while the base is in the open position, the interface 17 is released from the second locking member 19 which is in the deactivated state. The interface 17 can then be moved in translation by the fixing guide 30 (not shown) in order to extract the fabric anchor 11 from the housing 14 through the second opening 141. A dotted arrow is visible in [Fig. 14], it symbolizes the radial opening of the base 130 by rotation around the pivot connection 1305.

[0098] In [Fig. 16], the base 130 is completely open, it is thus possible to view the structure of the housing 14 and in particular of the annular passage 147 but also of the locking members 18, 19, or even of the first opening 140 arranged between the two cheeks 1309 which form the pivot connection 1305.

[0099] Consequently, according to this configuration, the housing 14 is movable in rotation relative to the reel 15 through the mobility of the base 130 relative to the receptacle 131.

[0100] In the embodiment illustrated in Figures 12 to 16, the anchor holder 10 may comprise a closing system. The closing system makes it possible to control the opening and closing of the base 130 relative to the receptacle 131. The closing system aims to prevent any untimely opening of the base 130. In this example, the closing system comprises a first element 60 mounted on the base 130 which is configured to clip onto a second element 61 disposed on the receptacle 131. In particular, the first element 60 is disposed at the top of a bead 1310 disposed on the rear face 138 of the base 130 see [Fig. 13]. The second opening 141 being provided at the lateral apex of the bead 1310. The second element 61 of the closure system is secured to the peripheral wall 135 of the receptacle 131. The position of the second element 61 on the peripheral wall 135 is defined so as to cooperate with the first element 60 when the base 130 is in the closed position. It should be noted that the bead 1310 gives the practitioner a grip to easily open the base 130.

[0101] According to this embodiment, the base 130 carries a downwardly oriented arrow 166 which is an indicator on how to open the base 130 to unlock the fabric anchor 11 and the suture thread 12.

[0102] According to this embodiment, the fixation kit 20 comprises holding means which are configured to hold the suture thread 12 near the rod 301 of the fixation guide 30 during insertion of the tissue anchor 11 into the patient's bone tissue. Here, the holding means comprise the annular passage 147 through which the suture thread 12 passes. In addition, the holding means comprise an annular seal 148 which is arranged in a slot 149 formed in the walls of the annular passage 147, this is illustrated in particular in the exploded view of [Fig. 12]. The annular seal 148 has an opening diameter smaller than the diameter of the annular passage 147. Its elastic nature makes it possible to hold the suture thread 12 against the rod 301 of the fixation guide 30.Indeed, the annular passage 147 divides the housing into two compartments, a first compartment located on the side of the first opening 140 and a second compartment located on the side of the second opening 141. Now, the suture thread 12 passes, via the passage 142, from the reel 15 into the first compartment of the housing 14, it is then connected to the anchor 11 in the second compartment by passing through the annular passage 147 and the annular seal. It should be noted that the second locking member 19 extends into the second compartment of the housing 14.

[0103] The annular seal 148 makes it possible to preserve the four strands of the two suture threads 12 near the rod of the fixing guide 30 as the practitioner approaches the end 300 of the fixing guide 30 of the pre-drilling.

[0104] As illustrated in Figures 1 to 7 and 9, the invention also relates to a fixing guide 30 which is complementary to the anchor holder 10 according to the invention.

[0105] [Fig. 9] illustrates the fixation guide 30 in isolation. During a surgical intervention, the fixation guide 30 makes it possible in particular to screw the anchor 11 into the bone tissue 50. For this purpose, the fixation guide comprises an assembly end 300 which is configured to be assembled to the head of the anchor 11. In this example, the assembly end 300 consisting of two pins of defined cross-section. In particular, the cross-section of each pin allows the assembly end 300 to fit into the head of the anchor 11. By way of example, each pin may comprise a cross-section consisting of three sides which allows fitting into an anchor head 11 of hexagonal shape.

[0106] As illustrated in [Fig.9], the assembly end 300 constitutes the tip of a rod 301 of the fixation guide 30. Furthermore, the fixation guide 30 comprises a handle 302 which allows practitioners to grasp and manipulate the fixation guide 30. As can be seen in particular in [Fig.9], the dimensions of the cross-section of the handle 302 may be greater than the dimensions of the cross-section of the rod 301.

[0107] In this example, the rod 301 extends longitudinally from the handle 302 towards the assembly end 300 of the rod 301. As illustrated in [Fig. 9], the fixing guide 30 comprises a groove 305, 306 which extends longitudinally at least between the assembly end 300 of the rod 301 and the handle 302. In the example of [Fig. 9], a first groove 305 is provided on the rod 301 between the two ends of the rod 301 and extends along the longitudinal axis BB. Furthermore, the first groove 305 may be extended by a second groove 306 which is provided on the handle 302. The second groove 306 is coaxial with the first groove 305.

[0108] According to this configuration, the housing 13 of the anchor holder 10 is configured to slide on the rod 301 from the assembly end 300 towards the handle 302. This is illustrated in Figures 5 and 6, the key 145 of the housing 14 is configured to slide in the groove 305. For this, the key 145 has a shape complementary to the groove 305. For example, an edge whose cross-sectional dimensions are smaller than the cross-sectional dimensions of the groove 305 in order to fit and slide in the groove 305. In addition, the groove 305 is configured to receive the suture thread 12 which is released by the reel 15 when the housing 13 is moved on the rod 301. This is visible in [Fig. 7] where the anchor 11 is inserted into the tissue bone while the reel 15 is placed in abutment with the handle 302, the suture thread 12 then extends from the anchor 11 to the reel 15 passing the groove 305.

[0109] The present invention also relates to a kit for fixing at least one suture thread in a biological tissue. This fixing kit comprises an anchor holder 10 and a fixing guide 30, both in accordance with the invention. The anchor holder and the fixing guide 30 are configured to cooperate during a surgical operation for ligament or tendon reconstruction. For example, the anchor holder 10 is movable in translation on the rod 301 of the fixing guide 30 while the housing 14 slides on the rod 301. In addition, the groove 305 of the rod 301 is configured to receive the suture thread 12 when the anchor holder 10 is moved towards the handle 302 on the rod 301 of the fixation guide 30.

[0110] The invention also relates to a method 40 for assembling a fixation guide and an anchor equipped with at least one suture thread configured to be inserted into a biological tissue. In accordance with the invention, the anchor and the suture thread are stored in an anchor holder which may be in accordance with the invention, just like the fixation guide and the anchor.

[0111] As illustrated in Figures 1 and 17, the assembly method 40 comprises a step 400 of inserting the assembly end 300 of the rod of the fixing guide into the housing 14 of the fixing device 10. Beforehand, the anchor holder is extracted from a sterile package while the fixing guide has been sterilized. Here, the assembly end 300 is inserted through the first opening 140 of the housing 14. During this step 300, the keying device 145 makes it possible to correctly position the assembly end 300 of the rod of the fixing guide in order to fit into the head of the anchor 11. In this example, the two pins of the assembly end 300 must be positioned on either side of the keying device 145 so that the free end 300 can penetrate the housing 14.

[0112] The assembly method 40 comprises a step 401 of assembling the assembly end 300 of the rod with the anchor 11. In practice, the assembly end 300 after insertion into the housing 14 is pushed to the bottom of the housing 14. In this example, the bottom of the housing 14 corresponds to the second opening 141 which at this stage of the assembly method 40 is obstructed by the locking member 16. The assembly end 300 is assembled by fitting onto the head of the anchor 11 which has an internal cross-section complementary to the assembly end 300. According to the embodiment illustrated in FIGS. 12 to 16, the assembly end 300 can also be assembled to the fabric anchor 11 by screwing through an interface 17.

[0113] As illustrated in Figures 4 and 17, the assembly method 40 comprises a step 402 of deactivating the locking member 16, 18, 19 in order to release the anchor 11 and the suture thread 12. According to the example of [Fig. 4], the locking member 16 passes from its activated state in which it is mounted on the base 130 of the housing 13 to its deactivated state in which the locking member 16 is detached from the base 130.

[0114] This step makes it possible, on the one hand, to open the second opening 141 of the housing 14 and to allow the movement of the anchor holder 10, and on the other hand, to release the suture thread 12 stored in the reel 15. In this example, the deactivated state of the locking member 16 makes it possible to release the rotation of the reel 15 which is rotatably mounted on the receptacle 131 of the housing 13.

[0115] In the embodiment of [Fig. 14], the base 130 moves from its closed position to its open position to deactivate the locking members 18, 19 in order to extract the fabric anchor 11 and release the rotation of the reel 15.

[0116] Moreover, the assembly method 40 also comprises a step 403 of moving the anchor holder 10 on the rod 301 in the direction of the handle 302 of the fixing guide 30. For this, the anchor holder 10 slides according to a longitudinal movement on the rod 301. The movement is done by translation of the housing 13 on the rod 301 which is inserted into the cavity of the housing 14. The keying device 145 can then perform a skate function in order to slide the housing 13 on the groove 305. In particular, during the movement of the anchor holder 10 the reel 15 releases suture thread 12 while the anchor 11 is arranged at the assembly end 300 of the fixing guide. According to this embodiment, suture thread 12 is unwound by rotation of the reel 15 around its axis and the suture thread 12 then engages in the groove 305 of the rod 301. This is made possible by the passage 142 which communicates between the reel 15 and the cavity of the housing 14. As illustrated in [Fig.6], the anchor holder 10 is moved until it comes into contact with the handle 302.

[0117] First, the assembly method 40 may include a step 404 of sterilizing the fixing guide 30. This sterilization step 404 may be carried out using a chemical agent such as ethylene oxide or using a physical method such as gamma ray irradiation.

[0118] The fixing kit is then ready to insert the anchor 11 carried by the fixing guide 30 into a pre-drilling which is carried out beforehand using a suitable device such as a center punch and / or a tap. For this purpose, the anchor 11 and more particularly its distal end 110 is positioned coaxially with the pre-drilling. In the embodiment of FIGS. 1 to 8, the insertion is carried out at least in part by screwing the threaded part of the anchor 11 into the pre-drilling. On the other hand, in the embodiment of FIGS. 12 to 16, the insertion is carried out by an impact which is generated by a fixing guide 30 of the impactor type. An impactor is a fixing guide 30 which comprises an internal shaft movable in translation, this shaft is connected, on the one hand, to the assembly end 300 of the fixing guide 30, and on the other hand, to a striking head which is located at the end of the handle 302.The surgeon usually strikes the striking head with a mallet to impact the bone tissue and force the tissue anchor 11 under the cortical portion of the bone.

[0119] The impacting support 172 which carries the tissue anchor 11 is projected into the pre-drilling, and upon its removal, the tissue forms a ball against the cortical part of the bone preventing the removal of the tissue anchor 11.

[0120] As can be seen in [Fig.7], once the anchor 11 is screwed into the pre-drilling, the rod 301 of the fixing guide 30 is disengaged from the head of the anchor 11. The anchor holder 10 is then removed from the rod 301 of the fixing guide 30, this is visible in [Fig.8]. The practitioner can then unwind the suture thread 12 to finish his repair operation.

[0121] The practitioner can then extract the reel 15 from the housing 13 by exerting traction on the disengagement means. The soft tissue (tendon or ligament) is bonded using the suture thread 12 which can be needled for this purpose. And finally, the soft tissue is brought closer to the bone tissue. When it is needled, the suture thread 12 cannot be removed from the reel 15 without the latter being extracted from the receptacle 131. Indeed, the needles do not pass through the passage 142 between the reel 15 and the housing. The surgeon can then extract the reel 15 on receptacle 131 by applying traction on the reel 15.
