Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an anchor cartridge, an anchor pre-loading unit, and an anchor implantation system. Background Technology

[0002] Existing bone anchors are all monolithic structures, consisting of inner row anchors with their own sutures for suturing bone and soft tissue, and outer row anchors without their own sutures for use as sutures after soft tissue and bone suturing, drawn from the inner row anchors. If multiple anchors are needed in a single surgery, each anchor is implanted separately to repair the bone and soft tissue. To address this cumbersome surgical procedure, a multi-anchor implant (or anchor assembly) has emerged, connecting multiple anchors in series for continuous implantation and fixation. However, existing series-type multi-anchor implants still have many technical drawbacks, severely restricting their clinical application and widespread adoption. Specifically, existing series-type multi-anchor implants typically rely solely on the flexible connection of sutures to connect multiple anchors, lacking effective storage and orderly management of each anchor. Due to the small size of the anchors, it is difficult to stably clamp and accurately position multiple anchors within the implantation instrument (such as the implantation rod), easily leading to problems such as anchor displacement or detachment before implantation, affecting the smooth progress of the implantation procedure. Summary of the Invention

[0003] The purpose of this application is to provide an anchor magazine, an anchor pre-installation unit, and an anchor implantation system to address at least one of the technical problems involved in the background art.

[0004] One aspect of this application provides an anchor cartridge, including a cartridge body and a plurality of anchor clamping assemblies for clamping anchors in a one-to-one correspondence. Each anchor clamping assembly is mounted on the cartridge body and arranged in a first direction. An insertion port is provided on each anchor clamping assembly for inserting an implantation rod into the anchor clamping assembly and contacting the corresponding anchor to push the anchor out of the anchor cartridge in a second direction. The first direction is the length direction of the cartridge body, and the second direction is perpendicular to the first direction.

[0005] Optionally, the anchor clamping assembly includes a first clamping member and a second clamping member, which are stacked in a third direction to clamp the anchor between the first clamping member and the second clamping member. The insertion port is located between the first clamping member and the second clamping member to separate the first clamping member and the second clamping member in the third direction during the process of the implantation rod extending into the insertion port and pushing the anchor clamping assembly, thereby pushing the anchor out of the chamber. The first direction and the second direction are both perpendicular to the third direction.

[0006] Optionally, the chamber is provided with a plurality of component receiving slots that penetrate the chamber in the second direction. Each component receiving slot is arranged in the first direction. Each anchor clamping component is correspondingly disposed in the component receiving slot. One end of the component receiving slot is the implantation rod inlet, and the other end of the component receiving slot is the anchor outlet. The insertion port is disposed facing the implantation rod inlet. The first clamping member and the second clamping member are used to separate from each other during the movement from the implantation rod inlet to the anchor outlet.

[0007] Optionally, the first clamping member includes a first body portion and a first slider portion. In the third direction, the first slider portion protrudes from the first body portion from a side opposite to the second clamping member. The inner wall of the component receiving groove is provided with a first limiting groove and a first slide rail extending in the second direction. The first limiting groove is located near the anchor outlet. The first slider portion slides in cooperation with the first slide rail. The first limiting groove is used to accommodate the first slider portion; and / or, The second clamping member includes a second body portion and a second slider portion. In the third direction, the second slider portion protrudes from the side opposite to the first clamping member of the second body portion. The inner wall of the component receiving groove is provided with a second limiting groove and a second slide rail extending in the second direction. The second limiting groove is located near the anchor outlet. The second slider portion slides in cooperation with the second slide rail. The second limiting groove is used to accommodate the second slider portion.

[0008] Optionally, the anchor cartridge provided in this application further includes a plurality of suture limiting portions disposed on the outer wall of the cartridge body. The number of suture limiting portions is the same as the number of component receiving slots. The component receiving slots located at both ends of the cartridge body in the first direction are respectively the first end component receiving slot and the last end component receiving slot. In the first direction, each suture limiting portion and each component receiving slot are staggered so that the end of the last end component receiving slot away from the first end component receiving slot is provided with the suture limiting portion. The suture limiting portion is provided with a suture clamp, and the inner wall of the suture clamp is used for frictional engagement with the suture.

[0009] Optionally, the suture limiting part located near the first end component receiving groove is the first end suture limiting part, and the other suture limiting parts besides the first end suture limiting part are provided with reserved suture loop clamps.

[0010] Optionally, the anchor magazine provided in this application further includes a limiting post disposed within the magazine body. The limiting post is disposed between any two adjacent component receiving slots in the first direction. The limiting post is provided with a transverse limiting groove and a longitudinal limiting groove, both with their openings facing away from the anchor outlet. The transverse limiting groove and the longitudinal limiting groove are both used to accommodate the suture. The transverse limiting groove penetrates the limiting post in the first direction. The longitudinal limiting groove extends upward in the third direction, with one end of the longitudinal limiting groove close to the suture limiting portion and the other end of the longitudinal limiting groove communicating with the transverse limiting groove.

[0011] Another aspect of this application provides an anchor pre-loading unit including an anchor assembly and an anchor magazine provided in this application. The anchor assembly includes a plurality of anchors and sutures wrapped around each of the anchors, and each of the anchor clamping assemblies clamps each of the anchors in a corresponding manner.

[0012] Optionally, each of the anchors is divided into a first anchor and a second anchor. The anchor clamping component disposed in the groove of the first end component is the first end anchor clamping component. The first end anchor clamping component clamps the second anchor, and the other anchor clamping components clamp the first anchor. The suture segment between the second anchor and the adjacent first anchor is disposed in the suture clamp on the first end suture limiting part. The suture segment between any two adjacent first anchors is disposed in the suture clamp at the corresponding position. The suture includes a plurality of reserved suture loops. Each reserved suture loop is disposed one-to-one with each of the first anchors, and each reserved suture loop cooperates one-to-one with each reserved suture loop clamp.

[0013] A third aspect of this application provides an anchor implantation system, including a handle, an implantation rod, and the anchor pre-installation unit provided in this application. The handle is provided with an assembly slot and a socket. The cartridge body cooperates with the assembly slot to allow the cartridge body to move relative to the assembly slot in a first direction. The socket penetrates the handle in a second direction. The implantation rod has a U-shaped port. The implantation rod is used to extend into the socket and pass through the implantation rod inlet and the socket in sequence to engage the anchor with the U-shaped port, thereby pushing the anchor out of the anchor cartridge.

[0014] The technical solution provided in this application can achieve at least one of the following beneficial effects: The anchor magazine, anchor pre-installation unit, and anchor implantation system provided in this application are equipped with multiple anchor clamping components arranged in the first direction. Each anchor clamping component fixes each anchor in a one-to-one correspondence through clamping, thereby realizing the storage and orderly management of each anchor. Moreover, the anchor clamping components can provide stable pre-positioning constraints for the anchors, reducing the possibility of the anchors being displaced or falling out of the anchor magazine due to external forces before implantation. This helps to maintain the accuracy of the position of each anchor in the anchor magazine, ensuring accurate docking between the implanted rod and the anchor, and thus making the implantation operation easier and smoother.

[0019] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figures 1 to 19d As shown, one aspect of this application provides an anchor cartridge, including a cartridge body 05 and a plurality of anchor clamping assemblies 07 for clamping each anchor in a one-to-one correspondence. Each of the anchor clamping assemblies 07 is mounted on the cartridge body 05 and arranged in a first direction. An insertion port 30 is provided on the anchor clamping assembly 07 for an implantation rod 03 to extend into the anchor clamping assembly 07 and contact the corresponding anchor, so as to push the anchor out of the anchor cartridge in a second direction. The first direction is the length direction of the cartridge body 05, and the second direction is perpendicular to the first direction.

[0023] Optionally, the anchor clamping assembly 07 includes a first clamping member 26 and a second clamping member 27, which are stacked in a third direction to clamp the anchor between the first clamping member 26 and the second clamping member 27. The insertion port 30 is located between the first clamping member 26 and the second clamping member 27 so that the first clamping member 26 and the second clamping member 27 separate from each other in the third direction during the process of the implantation rod 03 extending into the insertion port 30 and pushing the anchor clamping assembly 07, thereby pushing the anchor out of the chamber 05. The first direction and the second direction are both perpendicular to the third direction. In this way, the anchor is constrained by the relative positional relationship of the first clamping member 26 and the second clamping member 27 in the third direction. When the implantation rod 03 is not in contact with the anchor, the anchor is kept in a pre-positioned state in the chamber 05, so that the anchor is kept in a stable position before implantation. At the same time, when the implantation rod 03 pushes the anchor clamping assembly 07 in the second direction, the first clamping member 26 and the second clamping member 27 separate from each other in the third direction, so that the implantation rod 03 can push out the anchor in the second direction. The release and push-out of the anchor are completed in the same operation, without the need to set a separate operation step for opening the anchor clamping assembly 07, which helps to simplify the anchor implantation process.

[0024] Optionally, the chamber 05 is provided with a plurality of component receiving slots 11 that penetrate the chamber 05 in the second direction. Each component receiving slot 11 is arranged in the first direction. Each anchor clamping component 07 is correspondingly disposed in the component receiving slot 11. One end of the component receiving slot 11 is the implantation rod inlet, and the other end of the component receiving slot 11 is the anchor outlet 47. The insertion port 30 is disposed facing the implantation rod inlet. The first clamping member 26 and the second clamping member 27 are used to separate from each other during the movement from the implantation rod inlet to the anchor outlet 47. This allows each anchor clamping assembly 07 to have an independent accommodating space within the chamber 05, which helps reduce the possibility of positional interference between the anchor clamping assemblies 07 during the anchor ejection process. Moreover, the first clamping member 26 and the second clamping member 27 separate from each other during the movement from the implantation rod inlet to the anchor outlet 47, allowing the implantation rod 03 to cooperate with the anchor. The anchor is ejected from the anchor chamber while simultaneously disengaging from the anchor clamping assembly 07, eliminating the need for an additional opening operation of the anchor clamping assembly 07 after the anchor reaches the anchor outlet 47. This improves the continuity of anchor ejection and facilitates the smooth progress of the anchor implantation operation.

[0025] Optionally, the first clamping member 26 includes a first body portion and a first slider portion 24. In the third direction, the first slider portion 24 protrudes from the first body portion from the side opposite to the second clamping member 27. The inner wall of the component receiving groove 11 is provided with a first limiting groove 16 and a first slide rail 18 extending in the second direction. The first limiting groove 16 is located near the anchor outlet 47. The first slider portion 24 slides in cooperation with the first slide rail 18. The first limiting groove 16 is used to accommodate the first slider portion 24; and / or, The second clamping member 27 includes a second body portion and a second slider portion 29. In the third direction, the second slider portion 29 protrudes from the second body portion from the side opposite to the first clamping member 26. The inner wall of the component receiving groove 11 is provided with a second limiting groove 21 and a second slide rail 23 extending in the second direction. The second limiting groove 21 is located near the anchor outlet 47. The second slider portion 29 slides in cooperation with the second slide rail 23. The second limiting groove 21 is used to accommodate the second slider portion 29.

[0026] The first slider portion 24 protrudes from the first body portion along the third direction and slides in cooperation with the first slide rail 18, so that the first clamping member 26 is guided by the first slide rail 18 when it moves along the second direction, which helps to maintain the stability of the first clamping member 26 in the component receiving groove 11; the first limiting groove 16 is provided near the anchor outlet 47. When the first clamping member 26 moves along the second direction to the anchor outlet 47 position, the first slider portion 24 enters the first limiting groove 16, thereby restricting the first clamping member 26 from continuing to move forward in the second direction, which helps the anchor to be smoothly dislodged from the anchor outlet 47 of the component receiving groove 11. The second slider portion 29 protrudes from the second body portion along the third direction and slides in cooperation with the second slide rail 23, so that the second clamping member 27 is guided by the second slide rail 23 when it moves along the second direction, which helps to maintain the stability of the second clamping member 27 in the component receiving groove 11; the second limiting groove 21 is provided near the anchor outlet 47. When the second clamping member 27 moves along the second direction to the anchor outlet 47 position, the second slider portion 29 enters the second limiting groove 21, thereby restricting the second clamping member 27 from continuing to move forward in the second direction, which helps the anchor to be smoothly dislodged from the anchor outlet 47 of the component receiving groove 11.

[0027] Preferably, the first clamping member 26 further includes a third slider portion 25, the first slider portion 24 and the third slider portion 25 are arranged in the second direction, and the first slider portion 24 is disposed near the insertion port 30. The second clamping member 27 further includes a fourth slider portion 28, the second slider portion 29 and the fourth slider portion 28 are arranged in the second direction, and the second slider portion 29 is disposed near the insertion port 30. The inner wall of the component receiving groove 11 is also provided with a third limiting groove 17 and a fourth limiting groove 22, the first limiting groove 16 and the third limiting groove 17 are located on the same side and arranged in the second direction, and the third limiting groove 17 is disposed near the insertion port 30. An anchor outlet 47 is provided, and the second limiting groove 21 and the fourth limiting groove 22 are located on the same side and arranged in the second direction. The fourth limiting groove 22 is located near the anchor outlet 47. When the anchor clamping assembly 07 moves to a position near the anchor outlet 47, the third slider part 25 on the first clamping member 26 enters the third limiting groove 17, the first slider part enters the first limiting groove 16, the fourth slider part 28 on the second clamping member 27 enters the fourth limiting groove 22, and the second slider part enters the second limiting groove 21, thereby realizing the separation of the first clamping member 26 and the second clamping member 27 in the third direction.

[0028] Optionally, the anchor magazine provided in this application further includes a plurality of suture limiting parts 04 disposed on the outer wall of the magazine body 05. The number of suture limiting parts 04 is the same as the number of component receiving slots 11. The component receiving slots 11 located at both ends of the magazine body 05 in the first direction are the first end component receiving slot 11 and the last end component receiving slot 11, respectively. In the first direction, each suture limiting part 04 and each component receiving slot 11 are staggered so that the end of the last end component receiving slot 11 away from the first end component receiving slot 11 is provided with the suture limiting part 04. The suture limiting part 04 is provided with a suture clamp 37, and the inner wall of the suture clamp 37 is used for frictional engagement with the suture. This generates friction between the suture passing through the suture clamp 37 and the inner wall of the suture clamp 37. This friction resists the movement of the suture relative to the chamber 05, constraining the suture's path on the outer wall of the chamber 05 and providing path management for the suture during anchor loading and implantation. Furthermore, the number of suture limiting parts 04 is the same as the number of component receiving slots 11, and each suture limiting part 04 and each component receiving slot 11 are staggered in the first direction. The end of the first component receiving slot 11 away from the end of the last component receiving slot 11 has a suture limiting part 04, and the end of the last component receiving slot 11 away from the first component receiving slot 11 has a suture limiting part 04. The suture limiting part 04 is provided so that the suture segment included in each anchor unit can be constrained by the corresponding suture limiting part 04, which helps to reduce the possibility of suture segments of different anchor units getting tangled on the outer wall of the chamber 05; at the same time, when the implantation rod 03 pushes the anchor clamping assembly 07 to move in the second direction, the suture fixed on the anchor moves forward with the anchor. The friction between the inner wall of the suture clamp 37 and the suture keeps the suture taut during the movement, which helps the suture slide out of the suture clamp 37 along a predetermined path, thereby maintaining the stability of the suture's direction during the movement of the anchor.

[0029] Preferably, the suture limiting part 04 is provided with a first V-shaped groove, which is a through groove extending in the second direction. The port with a smaller area of ​​the V-shaped groove in the second direction is located near the inlet of the implant rod. The port with a smaller area is used to form the suture clamp 37. Further, a first protrusion 34 is provided on both side walls of the port with a smaller area, and a suture interface is formed between the two first protrusions 34. The first V-shaped groove is used to store the suture between two adjacent anchors, so that the suture is not easy to tangle or knot, and it is not easy to obstruct the implant rod 03 from extending into the anchor clamping assembly 07. The third-party upward suture limiting part 04 can be located on the side of the first clamping member 26 away from the second clamping member 27, or it can be located on the side of the second clamping member 27 away from the first clamping member 26. Preferably, during the use of the anchor cartridge, the suture limiting part 04 is located above the cartridge body 05. That is, during the operation of the anchor cartridge to insert the anchor, if the first clamping member 26 is generally located above, then the third-party upward suture limiting part 04 is located on the side of the first clamping member 26 away from the second clamping member 27. If the second clamping member 27 is generally located above, then the third-party upward suture limiting part 04 is located on the side of the second clamping member 27 away from the first clamping member 26.

[0030] Optionally, the suture limiting part 04 located near the first end component receiving groove 11 is the first end suture limiting part, and the other suture limiting parts 04 besides the first end suture limiting part are provided with reserved suture loop clamps 38. The reserved thread loop clamps 38 provided on the other suture limiting parts 04, except for the first end suture limiting part, are used to accommodate the reserved thread loops 35 led out from the corresponding anchor units. The inner wall of the reserved thread loop clamp 38 is in contact with the reserved thread loop 35, which can limit the position of the reserved thread loop 35 relative to the anchor chamber before the anchor is inserted, so that the reserved thread loop 35 maintains a predetermined shape in the anchor chamber, providing a basis for the reserved thread loop 35 to slide along a predetermined path in the subsequent tightening operation. At the same time, the first end suture limiting part does not have reserved thread loop clamps 38, which matches the feature that its corresponding anchor unit does not have reserved thread loops 35. The reserved thread loop clamps 38 are only provided on other suture limiting parts 04 that need to accommodate reserved thread loops 35, which helps to reduce the manufacturing difficulty and production cycle of the anchor chamber. Preferably, the suture limiting part 04 is provided with a second V-shaped groove, which is a through groove extending in a second direction. The port with a smaller area of ​​the V-shaped groove in the second direction is located near the inlet of the implant rod. The port with a smaller area is used to form the reserved suture loop clamping opening 38. Further, a second protrusion 36 is provided on both side walls of the port with a smaller area, and the reserved suture loop clamping opening 38 is formed between the two second protrusions 36. The second V-shaped groove is used to store the reserved suture loop 35 between two adjacent anchors, so that the reserved suture loop 35 is not easy to entangle or knot, and it is not easy to obstruct the implant rod 03 from extending into the anchor clamping assembly 07.

[0031] Optionally, the anchor magazine provided in this application further includes a limiting post 06 disposed within the magazine body 05. The limiting post 06 is disposed between any two adjacent component receiving slots 11 in the first direction. The limiting post 06 is provided with a transverse limiting groove 20 and a longitudinal limiting groove 19, both with their openings facing away from the anchor outlet 47. The transverse limiting groove 20 and the longitudinal limiting groove 19 are both used to accommodate sutures. The transverse limiting groove 20 penetrates the limiting post 06 in the first direction. The longitudinal limiting groove 19 extends in the third direction, with one end of the longitudinal limiting groove 19 close to the suture limiting part 04, and the other end of the longitudinal limiting groove 19 communicating with the transverse limiting groove 20.

[0032] The limiting post 06 is positioned between any two adjacent component slots 11 in the first direction, allowing the thread connecting two adjacent anchor components to be constrained by the limiting post 06 in the area between the two component slots 11. This ensures that the thread segment between adjacent anchors has a defined path within the anchor chamber, reducing the possibility of thread entanglement between adjacent component slots 11. Furthermore, the transverse limiting groove 20 penetrates the limiting post 06 in the first direction, and the longitudinal limiting groove 19 extends in the third direction, with one port of the longitudinal limiting groove 19 communicating with the transverse limiting groove 20. These two grooves form a cross-connected thread channel, thereby obtaining constraints in two different directions on the limiting post 06. This helps ensure that the thread moves according to the constraints defined by the transverse limiting groove 20 and the longitudinal limiting groove 19 during anchor movement. The directional sliding is achieved by the longitudinal limiting groove 19 having its other end port close to the thread limiting part 04, thus forming a continuous and defined path for the thread between the limiting post 06 and the thread limiting part 04. This helps reduce the possibility of the thread becoming loose or tangled between the limiting post 06 and the thread limiting part 04. At the same time, the openings of the transverse limiting groove 20 and the longitudinal limiting groove 19 are both set away from the anchor outlet 47, so that after the thread passes through the transverse limiting groove 20 and the longitudinal limiting groove 19 in the limiting post 06, it is located on the side away from the anchor outlet 47. When the anchor is pushed out from the anchor outlet 47, the thread moves towards the anchor outlet 47 under the action of the anchor. The thread is subjected to the frictional resistance of the inner walls of the transverse limiting groove 20 and the longitudinal limiting groove 19, providing structural conditions for the thread to remain taut during the movement of the anchor. Understandably, the number of limiting posts 06 is one less than the number of component receiving slots 11. When two component receiving slots 11 are provided in the compartment 05, one limiting post 06 is provided between these two component receiving slots 11 in the compartment 05. When three component receiving slots 11 arranged in the first direction are provided in the compartment 05, two limiting posts 06 are provided in the compartment 05: one limiting post 06 is provided between the first component receiving slot 11 and the second component receiving slot 11, and another limiting post 06 is provided between the second component receiving slot 11 and the third component receiving slot 11. This pattern continues when more than three component receiving slots 11 are provided in the compartment 05. A gap is provided between any two adjacent component receiving slots 11. The thread limiting part 04 is further provided with the limiting post 06. The thread clamp 37 of the thread limiting part 04 preferably corresponds to the port of the longitudinal limiting groove 19 at the corresponding position. Further, the compartment body 05 is provided with a connecting hole 14 extending upward in the third direction. One end of the connecting hole 14 is directly opposite the port of the longitudinal limiting groove 19, and the other end of the connecting hole 14 is opposite to the corresponding thread clamp 37. The threads on both sides of the limiting post 06 (i.e. the threads used for the anchors on both sides of the connecting rod limiting post 06) enter the transverse limiting groove 20 from both ends of the transverse limiting groove 20, and enter the connecting hole 14 from the longitudinal limiting groove 19. After passing through the connecting hole 14, they enter the thread clamp 37 of the thread limiting part 04.

[0033] Another aspect of this application provides an anchor pre-loading unit 02 including an anchor assembly and an anchor magazine provided in this application. The anchor assembly includes a plurality of anchors and stitching wrapped around each of the anchors, and each of the anchor clamping assemblies 07 clamps each of the anchors in a corresponding manner.

[0034] The anchor pre-installation unit 02 provided in this application is implemented using the anchor magazine provided in this application. It is provided with multiple anchor clamping components 07 arranged in the first direction. Each anchor clamping component 07 fixes each anchor in a one-to-one manner by clamping, thereby realizing the storage and orderly management of each anchor. The anchor clamping component 07 can provide stable pre-positioning constraints for the anchor, reducing the possibility of the anchor being displaced or falling out of the anchor magazine due to external forces before implantation. This helps to maintain the accuracy of the position of each anchor in the anchor magazine, ensuring accurate docking between the subsequent implantation rod 03 and the anchor, and making the implantation operation easier and smoother.

[0035] like Figures 17 to 19d As shown, the anchor assembly provided in this application includes a second anchor unit 55 and at least one first anchor unit 56. The first anchor unit 56 includes a first anchor 42, and the second anchor unit 55 includes a second anchor 40. When each anchor is implanted sequentially, the second anchor 40 is the first anchor implanted, and then each first anchor 42 is implanted sequentially.

[0036] Preferably, the anchor provided in this application is a U-shaped anchor with grooves 41 on both sides of the middle portion. A first limiting protrusion 31 is provided on the side of the first clamping member 26 facing the second clamping member 27, and a second limiting protrusion 32 is provided on the side of the second clamping member 27 facing the first clamping member 26. The first limiting protrusion 31 and the second limiting protrusion 32 are positioned opposite each other. When the anchor clamping assembly 07 clamps the anchor, the first limiting protrusion 31 and the second limiting protrusion 32 extend into the grooves 41 on both sides of the anchor, restricting the movement of the anchor in the first direction and guiding the movement of the anchor during insertion. The opening of the anchor faces the insertion port 30.

[0037] Optionally, each of the anchors is divided into a first anchor 42 and a second anchor 40. The anchor clamping component 07 disposed in the first end component receiving groove 11 is the first end anchor clamping component. The first end anchor clamping component clamps the second anchor 40, and the other anchor clamping components 07 clamp the first anchor 42. The suture segment 39 between the second anchor 40 and the adjacent first anchor 42 is disposed in the suture clamp 37 on the first end suture limiting part. The suture segment 33 between any two adjacent first anchors 42 is disposed in the suture clamp 37 at the corresponding position. The suture 57 includes a plurality of reserved suture loops 35. Each reserved suture loop 35 is disposed one-to-one with each of the first anchors 42, and each reserved suture loop 35 cooperates one-to-one with each reserved suture loop clamp 38. This allows the stitch segment 39 between the second anchor 40 and the adjacent first anchor 42 to pass only through the stitch clamp 37 on the first end stitch limiting part, without being constrained by the reserved thread loop clamp 38. The stitch segment 33 between any two adjacent first anchors 42 is set at the stitch clamp 37 of the corresponding stitch limiting part 04. The stitch segments included in different anchor units obtain different constraint paths according to the difference in the type of anchors they are connected to. Moreover, each first anchor 42 is provided with a reserved thread loop 35, and each reserved thread loop 35 corresponds to and cooperates with each reserved thread loop clamp 38. This allows the reserved thread loop 35 of each first anchor 42 to be independently constrained by the corresponding reserved thread loop clamp 38 in the anchor chamber. The reserved thread loops 35 are spatially isolated from each other, which helps to reduce the possibility of multiple reserved thread loops 35 crossing or tangling. This provides a structural basis for each first anchor 42 to independently complete the tightening operation of its respective reserved thread loop 35 during the subsequent knotting process. Understandably, in the embodiments of this application, each seam segment belongs to a single seam 57.

[0038] Understandably, the reserved thread loop 35 located on the first anchor 42 (the second anchor 40 adjacent to the second anchor 40) engages with the reserved thread loop clamp 38 between the first and second anchors 42; the reserved thread loop 35 located on the second anchor 42 engages with the reserved thread loop clamp 38 between the second and third anchors 42, and so on. Preferably, the stitch line between the reserved thread loop 35 and the two anchors engages with the transverse limiting groove 20 and the longitudinal limiting groove 19 on the limiting post 06, and then, after passing through the connecting hole 14, engages with the corresponding reserved thread loop clamp 38 and stitch clamp 37 respectively.

[0039] A third aspect of this application provides an anchor implantation system, including a handle 01, an implantation rod 03, and an anchor pre-installation unit 02 provided in this application. The handle 01 is provided with an assembly slot 49 and an insertion hole. The chamber 05 cooperates with the assembly slot 49 so that the chamber 05 can move relative to the assembly slot 49 in a first direction. The insertion hole penetrates the handle 01 in a second direction. The implantation rod 03 has a U-shaped port 54. The implantation rod 03 is used to extend into the insertion hole and pass through the implantation rod inlet and the insertion port 30 in sequence so that the anchor engages with the U-shaped port 54, thereby pushing the anchor out of the anchor chamber.

[0040] The assembly slot 49 on the handle 01 is used to cooperate with the housing 05 of the anchor pre-installation unit 02. The housing 05 can move relative to the assembly slot 49 in the first direction, so that multiple anchor clamping components 07 loaded in the housing 05 can slide along the first direction to reach the position aligned with the insertion hole in sequence. The anchors in each anchor clamping component 07 can be pushed out one by one in a predetermined order, which helps to shorten the time required for anchor switching during the continuous implantation of multiple anchors. At the same time, the U-shaped port 54 of the implantation rod 03 is used to engage with the anchor after the implantation rod 03 passes through the insertion port 30. The U-shaped port 54 forms an engaging fit with the outer wall of the anchor through the walls on both sides of its opening. When the implantation rod 03 continues to advance in the second direction, it transmits the thrust in the second direction to the anchor through the U-shaped port 54, pushing the anchor out of the component receiving slot 11. Thus, the transmission of thrust between the implantation rod 03 and the anchor can be achieved without an additional locking structure, which helps to simplify the docking operation between the implantation rod 03 and the anchor.

[0041] Understandably, before the first clamping member 26 and the second clamping member 27 separate from each other in a third direction, the implantation rod 03 continuously pushes the anchor clamping assembly 07 to move toward the anchor outlet 47 in a second direction. After the first clamping member 26 and the second clamping member 27 separate, the U-shaped port 54 of the implantation rod 03 is engaged with the anchor. The implantation rod 03 continues to push the anchor, and after the anchor is pushed out of the anchor chamber, it is implanted.

[0042] The anchor implantation system provided in this application is implemented using the anchor pre-installation unit 02 provided in this application. It is equipped with multiple anchor clamping components 07 arranged in the first direction. Each anchor clamping component 07 fixes each anchor in a one-to-one manner through clamping, thereby realizing the storage and orderly management of each anchor. Moreover, the anchor clamping component 07 can provide stable pre-positioning constraints for the anchor, reducing the possibility of the anchor being displaced or falling out of the anchor chamber due to external forces before implantation. This helps to maintain the accuracy of the position of each anchor in the anchor chamber, ensuring accurate docking between the subsequent implantation rod 03 and the anchor, and making the implantation operation easier and smoother.

[0043] Preferably, the housing 05 includes an upper cover 09 and a base 10, wherein the base 10 is an I-shaped base. The upper cover 09 and the I-shaped base are connected by an interference fit through holes on the left and right sides. The bottom of the mounting slot 49 on the handle 01 is provided with a guide rail 48 that mates with the I-shaped base. The top of the mounting slot 49 is provided with an opening 45 to prevent the stitch limiting part 04 from interfering with the handle 01 when the anchor cylinder moves. In addition to a ball screw 08, a plurality of positioning grooves 15 are provided on the upper cover 09 at the edge of the opening 45. Each positioning groove 15 corresponds one-to-one with the position of each component receiving groove 11. The positioning grooves 15 are used to mate with the ball screws 08 on the handle 01. The system restricts the sliding of the anchor cartridge; the suture limiting part 04 is provided on the upper cover 09, the limiting post 06 is fixed to the base 10, a first gap 12 is left between the limiting post 06 and the upper cover 09 for the suture 57 to pass through, and a second gap 13 is left between the upper cover 09 and the base 10 on the corresponding side of the anchor outlet 47 for the suture 57 to pass through; the anchor implantation system provided in this application preferably also includes an opening cone 43, which forms a bone tunnel of a certain depth by tapping, and then the opening cone 43 is removed. Preferably, the opening cone 43 passes through the insertion hole on the handle 01 and the anchor cartridge and reaches the bone surface, forms a bone tunnel of a certain depth by tapping, and then the opening cone 43 is removed. In this embodiment of the application, preferably, the handle 01 includes a handle 46, an outer tube 51, and an inner tube 52. The inner tube 52 is installed in the outer tube 51 and is coaxial with the outer tube 51. An insertion hole is formed in the handle 46. A cylindrical hole 50 coaxial with the insertion hole is provided at the front end of the handle 46. The inner tube 52 and the outer tube 51 are coaxially arranged and then installed into the cylindrical hole 50. One side of the inner tube 52 has a through groove structure. The outer tube 51 has a groove in the middle and a closed structure at both ends on one side.

[0044] In one application example of this application, the anchor implantation system operates as follows: The anchor pre-installation unit 02 is loaded into the assembly slot 49 of the handle 01, so that the housing 05 of the anchor pre-installation unit 02 mates with the assembly slot 49. The housing 05 can slide relative to the assembly slot 49 in the first direction. The ball screw 08 of the handle 01 fixes it in the first positioning slot 15. The first positioning slot 15 does not have anchors and anchor clamping components 07 installed at the corresponding position; it only serves as initial positioning. The housing 05 is pushed so that the first end component receiving slot 11 is aligned with the insertion hole of the handle 01. At this time, the ball screw 08 mates with the positioning slot 15 corresponding to the first end component receiving slot 11. The outer tube 51 of the handle 01 is passed through the soft tissue to the bone surface, so that the distal end of the outer tube 51 abuts against the bone surface. The opening cone 43 is tapped to form a bone tunnel of a certain depth, and then the opening cone 43 is removed. The chamber 05 is slid one position along the first direction, causing the ball screw 08 to engage with the corresponding positioning groove 15, fixing the component receiving groove 11 containing the second anchor 40 in a position aligned with the insertion hole. The implantation rod 03 is inserted through the insertion hole of the handle 01, passing sequentially through the implantation rod inlet and insertion port 30, and entering between the first clamping member 26 and the second clamping member 27. The implantation rod 03 continues to advance, first contacting and pushing the anchor clamping assembly 07 to move towards the anchor outlet 47 along the second direction. During the movement, the first clamping member 26 and the second clamping member 27 separate from each other in the third direction. After the first clamping member 26 and the second clamping member 27 separate, the U-shaped port 54 at the front end of the implantation rod 03 contacts and engages with the second anchor 40. The implantation rod 03 continues to advance, and the U-shaped port 54 pushes the second anchor 40 to continue moving along the second direction. The first clamping member 26 and the second clamping member 27 of the anchor clamping assembly 07 continue to move toward the anchor outlet 47 under the push of the implantation rod 03, until the first slider portion 24 of the first clamping member 26 enters the first limiting groove 16 and the second slider portion 29 of the second clamping member 27 enters the second limiting groove 21. The first clamping member 26 and the second clamping member 27 stop moving and separate from each other to a degree sufficient to release the second anchor 40. The second anchor 40 is dislodged from the anchor outlet 47 of the assembly receiving groove 11. The implantation rod 03 is continued to be advanced to deliver the second anchor 40 into the bone tunnel. The implantation rod 03 is tapped to implant the second anchor 40 into the bone tunnel. The implantation rod 03 is then removed. The implantation rod 03 will push the second anchor 40 and the suture segment on the second anchor 40 to move together. The suture segment 39 between the second anchor 40 and the adjacent first anchor 42 is positioned at the suture clamp 37 on the first end suture limiting part. The suture segment 39 is reserved long enough so that it always engages with the suture clamp 37 during the implantation of the second anchor 40. After the second anchor 40 is implanted, the suture segment 39 between the second anchor 40 and the adjacent first anchor 42 is pulled (e.g., ...). Figure 18(As shown), tighten the suture segment on the second anchor 40. Use the opening cone 43 to form the next bone channel, and remove the opening cone 43. Push the chamber 05 to slide along the first direction to the next station, so that the ball screw 08 engages with the next set of positioning grooves 15, and fix the component receiving groove 11 containing the first first anchor 42 in the position aligned with the insertion hole. Insert the first first anchor 42 into the bone channel. The implantation rod 03 will push the first anchor 42 and the suture segment on the first anchor 42 to move together. The suture segment 39 between the first anchor 42 and the second anchor 40 is reserved to a sufficient length, the reserved suture loop 35 corresponding to the first anchor 42 is reserved to a sufficient length, and the suture segment 44 between the first anchor 42 and the second anchor 42 is also reserved to a sufficient length. This ensures that during the implantation of the first anchor 42, the suture segment 39 between the first anchor 42 and the second anchor 40 is always engaged with the corresponding suture clamp 37, the reserved suture loop 35 corresponding to the first anchor 42 is always engaged with the corresponding reserved suture loop clamp 38, and the suture segment 44 between the first anchor 42 and the second anchor 42 is always engaged with the corresponding suture clamp 37. Figures 19a to 19d As shown, after the first anchor 42 is implanted, the corresponding reserved loop 35 is pulled to tighten the suture segment 39 between the first anchor 42 and the second anchor 40. Then, the suture segment 44 between the first anchor 42 and the second anchor 42 is pulled, compressing the pre-made knot 53 at the first anchor 42 into a locking knot. Each first anchor 42 is implanted sequentially, and the corresponding reserved loop 35 and suture segment are pulled until all anchors are implanted. The handle 01 and the anchor pre-installation unit 02 are then removed as a whole.
