Description

Technical Field

[0002] In surgeries such as large rotator cuff tears, complex labral injuries, ligament reconstruction, and other large-area injuries and complex anatomical repairs, a combination of multiple inner and / or outer rows of anchors is required to repair and fix soft tissues. However, in existing anchor implantation devices, the anchor implanters and anchors are used as a set in a one-to-one correspondence, and the anchor implanters are all disposable. When performing repair surgeries involving multiple anchor combinations, on the one hand, the doctor will reuse the anchor implanter each time he performs an implantation operation, which makes the operation cumbersome; on the other hand, one operation will cause multiple anchor implanters to be discarded, resulting in high surgical costs, waste of medical resources, and environmental pollution.

[0069] Embodiment 1:

[0070] like Figure 1-Figure 7 and Fig.17As shown, this embodiment provides an integrated module for multiple anchors, including a loading seat 1, a guide member 3 and two or more clamping assemblies 2, and the loading seat 1 is provided with an anchor loading area 11 and a guide displacement area 12. The two or more clamping assemblies 2 are arranged at intervals in the anchor loading area 11, and are used to clamp anchors, so as to realize the storage of more than two anchors, which is suitable for the combined use of multiple anchors of the same type or different types in surgery. The number and type of anchors stored on the loading seat 1 are set according to the requirements of different surgical procedures, which is convenient for preoperative material preparation. The guide member 3 is movably arranged in the guide displacement area 12, and a guide channel 31 is arranged on the guide member 3. The guide member 3 can be selectively moved to the guide channel 31 to be coaxial with any clamping assembly 2, and the guide channel 31 is used to guide the insertion of the inserter 300 and the anchor in the clamping assembly 2 coaxial therewith. The guide member 3 is movably arranged in the guide displacement area 12, and the guide member 3 moves to the guide channel 31 in the guide displacement area 12 to be coaxial with any clamping assembly 2, so that the inserter 300 is sequentially assembled with the anchors in more than two clamping assemblies 2 through the guide channel 31. That is, one inserter 300 can be assembled with multiple anchors, which realizes the reuse of the inserter 300, reduces the waste of medical resources, and simplifies the surgical operation.

[0071] The integrated module of multiple anchors is a disposable item, made of injection-molded degradable materials, which can reduce plastic pollution and is more environmentally friendly.

[0072] In one embodiment, if Figure 4 and Figure 5 As shown, the guide channel 31 is set as a U-shaped groove, and the bottom of the U-shaped groove is provided with V-shaped openings 311 at both ends of the guide member 3. In the initial state, the U-shaped groove can perform circumferential positioning on the insertion rod 302 of the inserter 300. After the insertion rod 302 is assembled with the anchor nail, the V-shaped opening 311 allows the guide member 3 to be elastically deformed, making it easier for the insertion rod 302 to be removed from the top.

[0073] In one embodiment, an anti-skid structure 34 is provided on the outer side of one end of the guide member 3 away from the central axis 32. Specifically, the anti-skid structure 34 is a square convex block with anti-skid patterns on the surface. During the assembly process of the inserter 300 and the anchor, the guide member 3 can be rotated by turning the square convex block to achieve the coaxiality of the guide channel 31 and different anchors. Optionally, the anti-skid patterns can be diamond patterns or horizontal or vertical stripes.

[0074] In one embodiment, guide protrusions 312 are symmetrically arranged on opposite sides of one end of the guide channel 31 away from the central axis 32. The two symmetrically arranged guide protrusions 312 guide the insertion rod 302 of the inserter 300 so that the insertion rod 302 can be accurately docked and assembled with the anchor.

[0075] Optionally, the guide protrusion 312 can be configured as a cylindrical or square block structure, etc., which needs to be compatible with the structure on the insertion rod 302.

[0076] The loading seat 1 can be set to a circular shape, a regular polygon, a combination of a semicircular shape and a regular polygon, or other shapes such as a square. In this embodiment, the corresponding anchor loading area 11 on the loading seat 1 is set to a regular polygon, the corresponding guide displacement area 12 is set to a semicircular shape, and a center hole 13 is set at the center of the loading seat 1.

[0077] Specifically, a central axis 32 is provided at one end of the guide member 3, and the central axis 32 is rotatably disposed in the central hole 13 of the loading seat 1. The guide member 3 is rotatably disposed in the central hole 13 of the loading seat 1 through the central axis 32, so that the guide channel 31 is coaxial with the anchors clamped by different clamping assemblies 2, so that the inserter 300 can be plugged and fixed with the tail end of the anchor through the guide channel 31 to realize the assembly of the inserter 300 and the anchor. After the inserter 300 is plugged and assembled with the anchor, the anchor is continuously pushed out of the loading seat 1, and the inserter 300 with the wire anchor is removed from the loading seat 1. Figure 1 and Figure 2 The Z-axis direction shown is separated from the integrated module of multiple anchors for implantation. After implantation of one anchor is completed, the guide member 3 rotates around the central axis 32 until the guide channel 31 is coaxial with the anchor held by the next clamping assembly 2, and the inserter 300 is again plugged and assembled with the next required anchor, and this cycle is repeated to achieve the insertion of the inserter 300 into the integrated module of multiple anchors.

[0078] Of course, in other embodiments, the loading seat 1 can also be set to a square shape, and the square loading seat 1 is divided into an anchor loading area 11 and a guide displacement area 12 with its central symmetry line as the dividing line, and the guide member 3 moves along the extension direction of the central symmetry line of the square loading seat 1 to achieve coaxiality with the anchors clamped by different clamping assemblies 2.

[0079] Furthermore, if Figure 3 and Figure 7 As shown, a limiting ring 14 is provided on one side of the center hole 13 corresponding to the anchor loading area 11, and both ends of the limiting ring 14 cooperate with the guide member 3 to limit the rotation limit position of the guide member 3. The limiting ring 14 is provided as a semicircular ring, and one side of the guide member 3 abuts against one end of the semicircular ring, indicating that the guide member 3 rotates to the first limit position; the other side of the guide member 3 abuts against the other end of the semicircular ring, indicating that the guide member 3 rotates to the second limit position, and the guide member 3 rotates between the first limit position and the second limit position, so that the guide channel 31 is coaxial with the anchors clamped by different clamping assemblies 2, respectively.

[0080] In one embodiment, if Figure 5 and Figure 7 As shown, a sliding member 33 is provided at the bottom of the guide member 3, and an annular slideway 121 is provided in the guide displacement area 12, and the sliding member 33 cooperates with the annular slideway 121. The annular slideway 121 is arranged with the center hole 13 as the center of the circle, so that the guide member 3 rotates with the center axis 32 as the axis of rotation under the guidance of the annular slideway 121. Specifically, the sliding member 33 is arranged as a spherical structure, and the cross-sectional design of the annular slideway 121 is a hemispherical guide surface matching the spherical structure, forming a rolling friction of point-to-surface contact; at the same time, combined with the concentric circle layout of the annular slideway 121 with the center hole 13 as the center of the circle, an axially constrained and radially freely rotating motion system is constructed to reduce the friction coefficient between the guide member 3 and the sliding member 33 of the spherical structure, so that the motion trajectory of the sliding member 33 accurately coincides with the curvature center of the annular slideway 121, thereby eliminating the phenomenon of eccentric wear, reducing wear, and extending the service life.

[0081] In one embodiment, if Figure 5 and Figure 6 As shown, the integrated module of multiple anchors also includes a bottom shell 6 fixed below the loading seat 1, a rotation groove 61 is provided in the bottom shell 6, and a guide tooth 611 is provided on the inner wall of the rotation groove 61. A tooth structure 321 is circumferentially provided at the bottom end of the central shaft 32, and the central shaft 32 passes through the loading seat 1. The tooth structure 321 cooperates with the guide tooth 611 to make the central shaft 32 rotate in one direction. The one-way rotation of the guide member 3 can prevent reverse rotation caused by accidental touch during use, which affects the assembly efficiency. At the same time, the tooth meshing structure will have an obvious sense of frustration and a rattling sound, which serves as a prompt for successful switching.

[0082] In one embodiment, the tooth structure 321 includes more than two ratchets, and the more than two ratchets are arranged in a one-to-one correspondence with the more than two clamping components 2. The tooth structure 321 is arranged corresponding to the anchor loading area 11, and the number of ratchets is consistent with the number of anchors, that is, one ratchets corresponds to one anchor. When the guide member 3 rotates, the frustration and rattling sound after the ratchets are engaged with the guide teeth 611 serve as a prompt for successful switching.

[0083] Specifically, one end of the guide tooth 611 is connected to the inner wall of the rotating groove 61, and the other end extends in parallel with the extension direction of the inner wall of the rotating groove 61 to reserve deformation space, so that during the rotation of the central shaft 32, the meshing of the guide tooth 611 and the tooth structure 321 can adaptively compensate the height difference between the tooth shapes through radial displacement. When the guide tooth 611 is subjected to force, it undergoes directional elastic bending along the extension direction, which not only avoids tooth surface wear caused by rigid contact, but also absorbs impact energy through the deformation space, while guiding the tooth meshing trajectory to always be coaxial with the rotation direction, significantly improving transmission stability and extending service life.

[0084] like Figure 6 and Fig.14As shown, three fixing sleeves 62 are arranged in the bottom shell 6 , and three second fixing columns 17 are arranged at the bottom of the loading seat 1 . The three second fixing columns 17 are interference fit with the three fixing sleeves 62 in a one-to-one correspondence to achieve the fixation of the bottom shell 6 and the loading seat 1 .

[0085] In one embodiment, if Figure 1 , Figure 7 and Figure 8 As shown, Y-shaped reinforcing ribs 111 are arranged at intervals along the circumference of the anchor loading area 11, the bottom of the Y-shaped reinforcing ribs 111 is arranged toward the center hole 13, and a clamping assembly 2 is arranged between two adjacent Y-shaped reinforcing ribs 111. By arranging the Y-shaped reinforcing ribs 111, the anchor loading area 11 is divided into two or more installation areas of the clamping assembly 2, which can support the clamping and fixing of more than two anchors at the same time. In addition, the spatial division of the anchor loading area 11 adopts the Y-shaped reinforcing ribs 111, which enhances the structural strength of the loading seat 1.

[0086] Specifically, the Y-shaped reinforcement rib 111 divides the anchor loading area 11 into four installation areas for the clamping components 2, and four clamping components 2 can be installed at the same time. A Y-shaped reinforcement rib 111 is cut from the middle into two sub-reinforcements, and the two sub-reinforcements are arranged at the junction of the anchor loading area 11 and the guide displacement area 12, and three Y-shaped reinforcement ribs 111 are arranged between the two sub-reinforcements to form four installation areas for the clamping components 2. Each anchor has a separate installation area to avoid interference and ensure the accuracy and independence of each anchor loading.

[0087] In one embodiment, the integrated module of multiple anchors further includes a cover shell 4 that is covered in the anchor loading area 11, and the cover shell 4 and the loading seat 1 jointly fix the clamping assembly 2, and an anchor outlet 5 is formed between the side wall of the cover shell 4 and the outer peripheral wall of the anchor loading area 11. The cover shell 4 plays the role of protecting the clamping assembly 2 and cooperating with the loading seat 1 to fix the clamping assembly 2, and after the anchor in the clamping assembly 2 is assembled with the inserter 300, the inserter 300 continues to apply force, and the anchor can be pushed out of the clamping assembly 2 from the anchor outlet 5.

[0088] Specifically, the three middle Y-shaped reinforcement ribs 111 and the two sub-reinforcement ribs are each provided with a first fixing hole 1111 at one end away from the center hole 13, and the cover shell 4 is provided with a first fixing column 42 corresponding to the first fixing hole 1111. The first fixing column 42 is interference fit with the first fixing hole 1111 to fix the cover shell 4 above the anchor loading area 11, thereby fixing and protecting the clamping assembly 2.

[0089] In one embodiment, if Figure 2 , Figure 9-13As shown, the clamping assembly 2 includes a first clamping block and a second clamping block, and the first clamping block and the second clamping block are butted together to form a clamping groove that is axially through and open at the top, and the clamping groove is adapted to the shape of the anchor and is used to clamp the anchor. By arranging the first clamping block and the second clamping block to butt together to clamp the anchor, the clamping operation of the anchor is facilitated, and after the inserter 300 is assembled with the anchor and the anchor is pushed out of the clamping assembly 2, the insertion rod 302 can be moved out through the upper opening of the clamping groove.

[0090] Specifically, one of the first clamping block and the second clamping block is provided with a claw, and the other is provided with a slot. After the first clamping block and the second clamping block are docked, the claw engages with the slot to achieve a fixed connection between the first clamping block and the second clamping block, so that the clamping slot can fix the anchor nail.

[0091] Furthermore, the top of the cover 4 is provided with a disengagement slot 41 corresponding to each clamping slot, which is adapted to the insertion rod 302 of the inserter 300. After the insertion rod 302 is removed from the upper opening of the clamping slot, the integrated module of multiple anchors is removed through the disengagement slot 41, so as to avoid the inserter 300 carrying the integrated module of multiple anchors when implanting the anchors, which affects the operation of the implantation surgery.

[0092] Specifically, the cover shell 4 is configured as a split structure, which is divided into five sub-cover shells, and adjacent sub-cover shells are spaced apart to form a disengagement slot 41. The inner walls of the five sub-cover shells are provided with a matching reinforcement structure corresponding to the three Y-shaped reinforcement ribs 111 and two sub-reinforcement ribs of the anchor loading area 11, and the first fixing column 42 is provided on the reinforcement structure. After the two adjacent sub-cover shells are respectively fixed with the two adjacent Y-shaped reinforcement ribs 111 through the first fixing column 42 and the first fixing hole 1111, they are respectively covered on the first clamping block and the second clamping block, and the disengagement slot 41 just corresponds to the upper opening of the clamping slot to ensure the stability of the fixation of the first clamping block and the second clamping block, while satisfying the insertion rod 302 of the inserter 300 from the upper opening of the clamping slot and the multi-anchor integrated module through the disengagement slot 41.

[0093] In one embodiment, the first clamping block and the second clamping block are provided with a plurality of elastic deformation grooves along the height direction on the opposite sides near one end of the anchor outlet 5, and the slot width of the elastic deformation groove gradually decreases with the increase of depth. The provision of the elastic deformation groove enables the first clamping block and the second clamping block to preferentially undergo elastic deformation along the slot direction of the elastic deformation groove when under pressure, and the deformation amount is positively correlated with the magnitude of the external force, thereby realizing dynamic adaptive adjustment of the clamping force, avoiding damage to the anchor surface due to over-tight clamping or slippage due to over-loose clamping; the through-type slot design ensures that the deformation is evenly distributed along the height direction of the clamping block, avoiding sudden changes in local stress, and improving the clamping stability. By arranging an elastic deformation groove at one end close to the anchor outlet 5, when the anchor is moved outward by the thrust of the inserter 300, the pressure on the contact surface between the first clamping block and the second clamping block triggers the expansion effect of the elastic deformation groove, forcing the first clamping block and the second clamping block to undergo synchronous elastic outward deformation in opposite directions at one end close to the anchor outlet 5, forming a progressive release channel, which facilitates the anchor to detach from between the first clamping block and the second clamping block and be pushed out through the anchor outlet 5.

[0094] Optionally, the cross-sectional shape of the elastic deformation groove is selected from one of a wedge-shaped groove or a V-shaped groove. When the first clamping block and the second clamping block are subjected to force, the elastic deformation of the notch structure can realize adaptive clamping force adjustment. The wedge-shaped groove or the V-shaped groove guides the deformation direction, which is convenient for the anchor to undergo elastic expansion deformation under force and can disperse local stress concentration. The through-type groove design simplifies the structural complexity, facilitates processing and reduces material costs.

[0095] The first clamping block and the second clamping block are both provided with positioning blocks at the bottom of one end close to the center hole 13, and the loading seat 1 is provided with positioning grooves for cooperating with the positioning blocks. When the first clamping block and the second clamping block are installed, the positioning blocks cooperate with the positioning grooves to realize the initial limiting of the clamping assembly 2.

[0096] In surgeries such as large rotator cuff tears, complex labral injuries, ligament reconstruction, and other large-area injuries and complex anatomical repairs, a combination of multiple inner row anchors 100 and / or outer row anchors 200 is required to repair and fix soft tissues. The inner row anchors 100 are usually placed on the joint side (inside) of the bone bed to directly fix the stop point of the soft tissue and ensure close contact between the tendon or ligament and the bone. The inner row anchors 100 are often equipped with high-strength sutures (such as non-absorbable sutures) for precise suturing and adjusting the tension of the soft tissue. The outer row anchors 200 are located on the outside of the bone bed. Their main function is to disperse the stress of the inner row anchors 100, increase the stability of the overall fixation, and expand the contact area between the soft tissue and the bone to promote healing. The outer row anchors 200 are mostly knotless designs, which fix the soft tissue by mechanical compression without sutures. The inner row anchors 100 directly bear the main tensile force, while the outer row anchors 200 reduce the load of the inner row sutures through the "pressurization effect", reducing the risk of suture breakage or anchor loosening.

[0097] The anchors include inner row anchors 100 and / or outer row anchors 200, and the two or more clamping assemblies 2 are all inner row clamping assemblies 2a or outer row clamping assemblies 2b; or, among the two or more clamping assemblies 2, one part is the inner row clamping assemblies 2a, and the other part is the outer row clamping assemblies 2b. Regarding the anchor types and the number of anchors of each type in the integrated module of multiple anchors, the integrated assembly of the number and type of anchors required for the procedure can be achieved according to the requirements of the procedure, and the precise guided assembly of the same inserter 300 and more than two anchors, as well as the separation of the assembled assembly from the integrated module of multiple anchors can be achieved. Each anchor has a separate installation area to avoid interference and ensure the accuracy and independence of each anchor assembly. At the same time, it has good scalability and user-friendliness, and can adapt to the needs of different surgical environments.

[0098] In this embodiment, there are two inner row anchors 100 and two outer row anchors 200 among the four anchors, and accordingly, the clamping assembly 2 includes two inner row clamping assemblies 2a and two outer row clamping assemblies 2b. The two inner row clamping assemblies 2a are arranged adjacent to each other, and the two outer row clamping assemblies 2b are arranged adjacent to each other; or, the two inner row clamping assemblies 2a are arranged between the two outer row clamping assemblies 2b.

[0099] like Figure 9-11As shown, the inner row clamping assembly 2a includes a first inner row clamping block 21a and a second inner row clamping block 22a. The clamping groove formed by the first inner row clamping block 21a and the second inner row clamping block 22a through the inner row clamping claw 28a and the inner row clamping groove 29a is an inner row clamping groove 23a adapted to the outer circumference of the inner row anchor 100. The inner row clamping groove 23a plays an axial positioning role for the inner row anchor 100. An inner row wire hole positioning platform 26a is relatively arranged at one end of the inner row clamping groove 23a close to the anchor outlet 5. The inner row wire hole positioning platform 26a cooperates with the inner row wire holes on the opposite sides of the inner row anchor 100 for positioning, and plays a limiting role for the circumference of the inner row anchor 100. A wire through hole 27a is relatively arranged at one end of the inner row clamping groove 23a away from the anchor outlet 5, which is used to guide the suture carried by the inner row anchor 100 to pass through the wire through hole 27a. The first inner row clamping block 21a and the second inner row clamping block 22a are both provided with inner row elastic deformation grooves 24a on the opposite sides near the anchor outlet 5, so that the inner row anchor 100 can be smoothly pushed out of the inner row clamping grooves 23a. The first inner row clamping block 21a and the second inner row clamping block 22a are both provided with inner row positioning blocks 25a at the bottom at the ends away from the anchor outlet 5, which are used for the initial limiting of the first inner row clamping block 21a and the second inner row clamping block 22a.

[0100] like Fig. 9 , Fig.12 and Fig.13 As shown, the outer row clamping assembly 2b includes a first outer row clamping block 21b and a second outer row clamping block 22b. The clamping groove formed by the first outer row clamping block 21b and the second outer row clamping block 22b through the outer row clamping claw 27b and the outer row clamping groove 28b is an outer row clamping groove 23b adapted to the outer circumference of the outer row anchor 200. The outer row clamping groove 23b plays an axial positioning role for the outer row anchor 200. An outer row wire hole positioning platform 26b is arranged at one end of the outer row clamping groove 23b close to the anchor outlet 5. The outer row wire hole positioning platform 26b cooperates with the outer row wire hole for positioning, and plays a limiting role for the circumference of the outer row anchor 200. The first outer row clamping block 21b and the second outer row clamping block 22b are arranged at one end close to the anchor outlet 5, and the outer row elastic deformation groove 24b is arranged on the opposite side, so that the outer row anchor 200 can be smoothly pushed out of the outer row clamping groove 23b. The first outer row clamping block 21b and the second outer row clamping block 22b are both provided with outer row positioning blocks 25b at the bottom of one end away from the anchor outlet 5 for initial limiting of the first outer row clamping block 21b and the second outer row clamping block 22b.

[0101] The clamping assembly 2 provided in this embodiment is used to clamp the anchor. The open design above the clamping groove of the clamping assembly 2 allows the insertion rod 302 of the inserter 300 to be removed from the top of the multi-anchor integrated module after the anchor and the inserter 300 are assembled. There is no need to carry the entire multi-anchor integrated module for anchor implantation and fixation, and the surgical procedure is simple and convenient. The design of the elastic deformation grooves on both sides of the clamping assembly 2 can not only achieve the initial limit and fixation of the anchor in the initial clamping state, but also have sufficient elasticity to support the deformation of the clamping assembly 2 during the process of the anchor pushing out of the clamping assembly 2, thereby ensuring the integrity of the coordination between the anchor and the inserter 300.

[0102] In one embodiment, if Figure 6 , Figure 14-16 As shown, the integrated module of multiple anchors also includes a winding wheel 7, which is rotatably arranged in the bottom shell 6, and a wire collection hole 15 is provided on the loading seat 1 corresponding to each clamping assembly 2, and the suture of the anchor with suture passes through the wire collection hole 15 and is wound around the winding wheel 7. By providing a wire collection hole 15 corresponding to each clamping assembly 2 on the loading seat 1, the installation area of ​​the inner row clamping assembly 2a in the anchor loading area 11 is not limited, and the routing of the suture of the inner row anchor 100 in any installation area is satisfied.

[0103] Specifically, two winding wheels 7 are provided, and the sutures of the two inner row anchors 100 are wound on the two winding wheels 7 one by one. The winding wheel 7 includes a wheel body 71 and positioning flanges provided at both ends of the wheel body 71, wherein the positioning flange at one end is provided with wire clamping grooves 72 at intervals along the axial direction, and the sutures of the inner row anchors 100 are passed through the wire collection holes 15 into the bottom shell 6 and then wound on the wheel body 71 and fixed through the wire clamping grooves 72. The positioning flange at the other end is provided with elastic ratchets 73 at intervals along the circumferential direction.

[0104] The bottom of the loading seat 1 is provided with a circular groove 16, and a positioning flange provided with a wire clamping groove 72 is placed in the circular groove 16, and the circular groove 16 is used to limit the position of the winding wheel 7. Two circular mounting grooves 63 are provided in the bottom shell 6, and a mounting shaft 64 is provided at the center of each circular mounting groove 63. The wheel body 71 is sleeved on the mounting shaft 64 and can rotate relative to the mounting shaft 64. The inner wall of the circular mounting groove 63 is provided with an inner ratchet 631, and the elastic pawl 73 cooperates with the inner ratchet 631. In the process of the suture driving the wheel body 71 to rotate, a rotation resistance is provided to the rotation of the winding wheel 7, so that the suture has a certain tension.

[0105] In one embodiment, the wire collecting hole 15 is set as a T-shaped slot, the longitudinal slot of the T-shaped slot is used for the suture to pass through, and the transverse slot of the T-shaped slot is used as a positioning slot that cooperates with the positioning block at the bottom of the clamping assembly 2. When installing the clamping assembly 2, the two positioning blocks of the clamping assembly 2 are both positioned in cooperation with the transverse slot of the T-shaped slot for initial positioning of the clamping assembly 2. The suture of the inner row anchor 100 passes through the wire through hole 27a at one end of the inner row clamping groove 23a away from the anchor outlet 5, and then passes through the longitudinal slot of the T-shaped slot and is wound on the winding wheel 7 in the bottom shell 6.

[0106] The integrated module of multiple anchors provided in this embodiment manages anchors and sutures separately. The sutures of the inner row anchors 100 pass through the inner row wire holes of the inner row anchors 100 and then through the wire through holes 27a on the inner row clamping assembly 2a, bringing the sutures close to both sides of the inner row anchors 100, thereby reducing the influence of the sutures on the inserter 300 and the anchors during assembly. Then, they enter the bottom shell 6 through the longitudinal groove of the T-slot and are wound on the winding wheel 7 in the bottom shell 6. The anchors and sutures are managed in layers, and the sutures are tensioned and wound on the winding wheel 7 of the lower layer. During the anchor push-out process, the sutures pull the winding wheel 7 to rotate, and the design of the elastic ratchet 73 allows the sutures to always maintain a certain tension, thereby avoiding the messy management caused by the loosening of the sutures during the operation.

[0107] Embodiment 2:

[0108] like Figure 17-Figure 21 As shown, this embodiment provides a separate implantation system for multiple anchors, including an inserter 300 and the integrated module for multiple anchors described in the first embodiment, wherein the inserter 300 is used to be respectively plugged and fixed with the anchors in two or more clamping assemblies 2 and to push the anchors out of the loading seat 1. In the separate implantation system for multiple anchors, the inserter 300 and the integrated module for multiple anchors are separately arranged, and the inserter 300 and the integrated module for multiple anchors are separately packaged, and one inserter 300 can be adapted to the implantation of multiple anchors in one or more integrated modules for multiple anchors, and the integrated module for multiple anchors can be integrated and assembled according to the number and type of anchors required for the surgical procedure, and the inserter 300 can accurately assemble more than two anchors under the guidance of the guide 3 in the integrated module for multiple anchors, and implant and fix the anchors, which can meet the needs of different surgical environments, reduce the waste of medical resources, simplify surgical operations, and facilitate the preparation of preoperative materials.

[0109] The inserter 300 includes a handle 301 and an insertion rod 302. One end of the insertion rod 302 is connected to the handle 301, and the other end is provided with a plug connector 303. The insertion rod 302 cooperates with the guide channel 31 to guide the plug connector 303 to be plugged with the anchor.

[0110] The outer peripheral wall of the handle 301 is provided with a water drop streamline shape, which is in line with ergonomics. The end of the handle 301 away from the insertion rod 302 is provided with a tail cap 3011. During implantation, the insertion rod 302 is forced by knocking the tail cap 3011 to achieve implantation of the anchor. The end of the handle 301 close to the insertion rod 302 is provided with anti-skid grooves 3012 at intervals along the circumferential direction, which play an anti-skid role when holding the handle 301 to assemble the anchor.

[0111] Two vertical planes 3021 are arranged opposite to one end of the insertion rod 302 connected to the handle 301. When the insertion rod 302 and the handle 301 are connected by injection molding, the vertical planes 3021 can increase the connection strength between the two.

[0112] The plug connector 303 is configured as a flat head, which is inserted into the tail end of the anchor to realize the assembly of the anchor and the inserter 300. Guide grooves 3022 are provided on the opposite sides of the insertion rod 302 and the flat head. The guide grooves 3022 cooperate with the guide protrusions 312 in the guide channel 31 to guide the insertion rod 302 to accurately dock with the anchor.

[0113] The peripheral wall of the plug connector 303 is symmetrically provided with guide grooves 3031 for guiding the sutures. The guide grooves 3031 are smoothly connected to the guide grooves 3022 , and the guide grooves 3031 are arranged closer to the axis of the plug connector 303 , so as to guide the sutures to be close to the plug connector 303 .

[0114] The method of using the multiple anchor separation implantation system provided in this embodiment is as follows: in an operation using multiple anchors, according to the requirements of the procedure, first use the anti-slip structure 34 on one side of the guide member 3 to toggle the guide member 3 so that the guide member 3 moves to the corresponding position, and stops moving when the toothed structure 321 of the central axis 32 is engaged with the guide tooth 611 and the rattle is heard. At this time, the guide channel 31 and the anchor in the clamping assembly 2 are on the same axis. Hold the handle 301 of the inserter 300, engage the guide groove 3022 of the plug connector 303 of the insertion rod 302 with the guide protrusion 312 of the guide channel 31, so that the insertion rod 302 is limitedly pushed into the guide channel 31 along the axial direction until the anchor assembly is inserted into the plug connector 303 of the inserter 300, and then continues to be completely pushed out of the integrated module of the multiple anchors along the axial direction, and the insertion rod 302 of the inserter 300 is disengaged from the integrated module of the multiple anchors from the disengagement groove 41, and finally the anchor is implanted into the bone channel through the inserter 300. After the first anchor is implanted successfully, the guide member 3 is moved clockwise to the next anchor clamping position, and the above steps are repeated to complete the assembly of the remaining anchors and the inserter 300, and the implantation of the anchors. Finally, the excess sutures are cut off to complete the fixation.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
