[0002] This application claims priority to Chinese patent application 2024117747078, filed on December 5, 2024, entitled “Separate Modular Wire Anchor Implantation System”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of medical device technology, and in particular to a detachable modular suture anchor implantation system. Background Technology

[0004] Anchors are widely used for fixing bones and soft tissues. They can be used around the shoulder, knee, hip, elbow, wrist, and ankle to simply and effectively fix soft tissues (such as tendons and ligaments) to bones using anchors and sutures, and keep them in place without loosening or excessive tension until healing.

[0005] In existing bone anchor implantation systems, the inserter, anchor, and suture are pre-assembled as a single unit. During surgery, the inserter, anchor, and suture must be used as a set, which means that the inserter is discarded directly after surgery. However, in actual surgery, the number and type of anchors are selected according to actual needs, resulting in the discarding of multiple inserters in one surgery. The inserters cannot be reused, which not only wastes medical resources and pollutes the environment, but also hinders surgical procedures. Summary of the Invention

[0006] One of the objectives of this application is to provide a separate modular suture anchor implantation system, which enables separate storage of anchors and sutures, while allowing for free assembly of anchors and inserters. The inserters are reusable, reducing waste of medical resources and simplifying surgical procedures.

[0007] To achieve this objective, the following technical solution is adopted in this application:

[0008] A modular, separate wire anchor implantation system, comprising:

[0009] An inserter includes an insert rod, the head of which is provided with a plug-in portion;

[0010] A storage box containing anchors has an inlet and an outlet at each end. An insertion rod can be inserted into the storage box through the inlet, allowing the insertion part to engage with the anchor, and the anchor is pushed out through the outlet to complete the assembly of the inserter and the anchor. After the inserter inserts the anchor, moving it in the opposite direction to the insertion direction disengages the insertion part from the anchor.

[0011] As an optional solution for the separate modular wire anchor implantation system, the storage box is provided with an anchor clamping assembly. The anchor clamping assembly includes an elastic element and two symmetrically arranged jaws. The two jaws are connected by the elastic element to form a receiving cavity. The inlet and the outlet are both connected to the receiving cavity, and the anchor is stored in the receiving cavity. The two jaws are slidably disposed in the storage box. Under the pushing force of the insertion rod, the ends of the two jaws near the outlet slide open in a direction away from each other to push the anchor out of the storage box.

[0012] As an alternative to the split modular wire anchor implantation system, the center line of the receiving cavity is set to coincide with the symmetry line of the two grippers;

[0013] Alternatively, the centerline of the receiving cavity is perpendicular to the symmetry line of the two grippers, and after the two grippers are connected, a through hole is formed in which the centerline coincides with the symmetry line of the two grippers, and the through hole is used for the insertion rod to pass through.

[0014] As an optional solution for the split modular wire anchor implantation system, the storage box is provided with a slide rail, and the gripper is provided with a sliding column that is slidably connected to the slide rail.

[0015] Each of the grippers has a sliding column at both ends on the same side. The slide includes a first slide and a second slide. The first slide is located near the inlet, and the second slide is located near the outlet. Both the first slide and the second slide extend away from the grippers and towards the outlet. The angle between the first slide and the line of symmetry of the two grippers is smaller than the angle between the second slide and the line of symmetry of the two grippers.

[0016] Alternatively, a slide post may be provided on the same side of each of the grippers, and the slide extends in a direction away from the grippers and closer to the outlet.

[0017] As an optional solution for the split modular wire anchor implantation system, a semi-annular groove is provided along the circumference of the gripper, and the semi-annular grooves of the two grippers are joined to form an installation groove, and the elastic element is provided in the installation groove.

[0018] Alternatively, the elastic element may be arranged around the sliding pillars disposed opposite to each other on the two grippers.

[0019] As an optional solution for the separate modular wire anchor implantation system, the storage box is also provided with an insertion channel. The center line of the anchor clamping assembly and the center line of the insertion channel are on the same straight line. One end of the insertion channel is connected to the inlet, and the other end is connected to the receiving cavity or the outlet.

[0020] As an optional solution for the separate modular suture anchor implantation system, the storage box also stores sutures, and suture winding structures are symmetrically arranged on both sides of the anchor. After the suture passes through the anchor, its two ends are connected to the two suture winding structures respectively. The insertion rod drives the storage box to move in the opposite direction to the implantation direction, and the suture winding structures can release the sutures.

[0021] As an optional solution for the separate modular suture anchor implantation system, the suture storage and winding structure includes a ratchet, which is rotatably disposed within the storage box; the ratchet includes a central shaft and two baffles disposed at both ends of the central shaft, and the baffles are provided with suture take-up grooves at intervals, the suture is wound around the central shaft, and the tail end of the suture is inserted into two adjacent suture take-up grooves.

[0022] As an alternative to the split modular wire anchor implantation system, multiple elastic pawls are provided at circumferential intervals along the baffle, forming an annular groove between the elastic pawls and the baffle, and a take-up groove extending radially along the baffle is provided on the inner side of each annular groove.

[0023] As an alternative to the split modular suture anchor implantation system, a guide damping post is also provided on the periphery of the ratchet, and the suture passing through the anchor wraps around the guide damping post and around the central axis.

[0024] As an optional solution for the separate modular wire anchor implantation system, the wire storage and winding structure includes a winding groove and a take-up hole. The winding grooves are symmetrically arranged on the outer periphery of the storage box, and one of the winding grooves has a wire passage hole. The take-up hole is symmetrically arranged on the outer periphery of the storage box and communicates with the interior of the storage box. The suture passing through the anchor passes through the wire passage hole and is wound in the oppositely arranged winding groove, and the tail end of the suture is inserted into the oppositely arranged take-up hole.

[0025] The lines of symmetry of the winding groove and the take-up hole are both perpendicular to the line connecting the inlet and the outlet.

[0026] As an optional solution for the separate modular suture anchor implantation system, the suture storage and winding structure further includes a suture storage groove, which is located inside the storage box. The suture can be confined within the suture storage groove, and the suture passing through the anchor is led out through the suture storage groove and then passes through the suture hole.

[0027] As an optional solution for the separate modular suture anchor implantation system, the suture storage and winding structure further includes a tensioning member, which is located between the anchor and the suture storage groove. The suture passing through the anchor is tensioned by the tensioning member and then enters the suture storage groove.

[0028] As an alternative to the separate modular wire anchor implantation system, the inserter also includes a handle, one end of which is provided with a bayonet. The insertion rod extends into the bayonet and is detachably connected to the handle. The bayonet is used to clamp the storage box.

[0029] As an optional solution for the separate modular wire anchor implantation system, the storage box is provided with a spherical groove, and a positioning bead is provided on one side of the bayonet. The positioning bead can cooperate with the spherical groove to fix the inserter and the storage box.

[0030] As an optional solution for the split modular wire anchor implantation system, a snap-fit ​​component is provided on one side of the bayonet. The snap-fit ​​component is rotatably connected to the handle and is used to cooperate with the other side wall of the bayonet to clamp the storage box. When one end of the snap-fit ​​component is pressed, the other end of the snap-fit ​​component can move away from the other side wall of the bayonet.

[0031] As an optional solution for the split modular wire anchor implantation system, the storage box is provided with multiple slots, and the other end of the snap-fit ​​component is provided with multiple protrusions, which engage with the slots.

[0032] As an alternative to the split modular wire anchor implantation system, the plug-in part includes a prism-shaped head, an inner hole-shaped head, or a fork-shaped head.

[0033] As an optional embodiment of the split modular wire anchor implantation system, the plug-in part includes a plug-in rod with a diameter smaller than that of the insertion rod. The plug-in rod is provided with a stress relief platform and a marking line, with the marking line located between the stress relief platform and the insertion rod.

[0034] As an optional solution for the split modular wire anchor implantation system, the insertion rod is provided with a guide boss.

[0035] As an alternative to the separate modular wire anchor implantation system, the storage box includes a box body, which includes a top shell and a bottom shell that are snap-fitted together.

[0036] The beneficial effects of this application are:

[0037] The separate modular suture anchor implantation system provided in this application stores the anchors and sutures in a storage box. This allows for separate storage of the anchors and sutures, and the storage box assembles the anchors and sutures into the inserter. During use, only the storage box needs to be replaced; the inserter itself does not need to be replaced, thus achieving reusability of the inserter. Compared to related technologies where anchors and inserters are pre-assembled in a one-to-one correspondence, requiring the inserter to be replaced when changing an anchor, this separate modular suture anchor implantation system offers several advantages. First, the inserter is reusable, reducing unnecessary medical waste, conserving medical resources, and benefiting the environment. Second, by separating the anchors and inserter, and with the storage box suitable for storing multiple anchors, if the planned anchor size or type is found to be unsuitable during surgery, the material replacement can be quickly completed by simply changing the storage box. Therefore, during surgery, only the storage box needs to be replaced to select the appropriate anchor, simplifying the surgical procedure and adapting to complex and varied surgical scenarios. Furthermore, since the anchors and sutures are stored in the storage box and assembled with the insertion rod during the operation, the risk of contamination from anchor exposure during preoperative preparation is avoided. Additionally, the anchor clamping assembly in the storage box fully restricts the anchor's freedom of movement, preventing misalignment, detachment, or jamming. Simultaneously, the sutures in the storage box, through a suture winding structure, can be automatically released after implantation, with automatic tension adjustment during release. The sutures are released orderly without the risk of tangling, eliminating the need for manual untying or additional adjustments by the surgeon, significantly reducing procedures and surgical time.

[0087] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0088] As shown in Figures 1-44, this application provides a separate modular suture anchor implantation system, including an inserter 1 and a storage box 2. The storage box 2 stores anchors and sutures 200. The anchors and sutures 200 can be stored in one storage box 2 or separately in different storage boxes 2. During the implantation surgery, the inserter 1 is inserted into the storage box 2 to assemble with the anchor. After the anchor is pushed out of the storage box 2 using the inserter 1, the inserter 1 is fixed to the storage box 2, thus assembling the inserter 1 with the anchor. Then, the anchor is implanted into the bone using the inserter 1. Finally, force is applied to the inserter 1 in the opposite direction to the implantation direction to disengage the inserter 1 from the anchor, releasing the sutures 200. This simplifies the surgical procedure and improves surgical efficiency. Finally, the storage box 2 is removed from the inserter 1. The inserter 1 is reusable; only the storage box 2 needs to be replaced. This solves the problems of resource waste and environmental pollution caused by the requirement for the anchor and inserter 1 to be used as a set in related technologies, and the use of disposable inserter 1. Simultaneously, the reusability of inserter 1 saves costs while ensuring structural strength, reducing the frequency of intraoperative instrument failure due to quality issues with inserter 1. Storing the anchor and suture 200 separately in the storage box 2 prevents the anchor from being exposed and contaminated during preoperative preparation, reducing surgical risks. Furthermore, the small size of the storage box 2 allows for the preparation of a sufficient number and variety of storage boxes 2 preoperatively to ensure a response to unexpected intraoperative situations.

[0089] The modular suture anchor implantation system provided in this application is applicable to the implantation of anchors of various materials and shapes. For example, according to different materials, it is divided into metal anchors, polyetheretherketone anchors, absorbable anchors, full suture anchors 103, and interface anchors, etc.; according to different shapes, it is divided into boss anchors 101 and inner hole anchors 102. In addition, the shape of the full suture anchor 103 is different from the shape of the boss anchor 101 and the inner hole anchor 102.

[0090] The inserter 1 includes a handle 11 and an insertion rod 12. One end of the handle 11 is provided with a bayonet 111. The insertion rod 12 extends into the bayonet 111 and is detachably connected to the handle 11. The bayonet 111 is used to hold the storage box 2. Force is applied to the insertion rod 12 by the handle 11 to insert the insertion rod 12 into the storage box 2 and push out the anchor. Force is also applied to the anchor by the handle 11 during the anchor insertion process. The head of the insertion rod 12 is provided with a plug-in part 13, which is used to plug into the anchor. Different plug-in parts 13 are adapted according to the different materials and shapes of the anchors.

[0091] For example, for the full suture anchor 103 and the percussion-type implantation anchor, the end of the handle 11 is struck with a hammer to drive the anchor into the predetermined position and depth, and the striking action is then stopped. Then, holding the handle 11 of the inserter 1, it is pulled out in the opposite direction to the implantation direction, and the storage box 2 releases the suture 200. When the suture 200 is completely removed from the storage box 2, the implantation is completed.

[0092] The insertion rod 12 has an external thread at the end away from the connector, and a threaded hole 115 is provided at the center of the bottom of the bayonet 111. The insertion rod 12 extends into the threaded hole 115 and is screwed onto the handle 11, allowing for quick replacement of the insertion rod 12. Different types and specifications of insertion rods 12 can be used for anchors of different materials and shapes. The connector 13 is welded to the insertion rod 12, providing guidance and mating functions while ensuring the reliability of the connection between the connector 13 and the insertion rod 12. This prevents medical accidents caused by the connector 13 remaining in the bone when force is applied in the opposite direction to the implantation direction, which could lead to the insertion device 1 disengaging from the anchor.

[0093] Furthermore, a weight-reducing cavity 114 is provided at the end of the handle 11 away from the bayonet 111 to reduce the overall weight of the inserter 1.

[0094] Since the inserter 1 is a reusable surgical tool, the cost of key components of the inserter 1 can be appropriately increased to ensure quality and improve mechanical stability. Both the insert rod 12 and the insertion part 13 are made of hard stainless steel, which is much stronger than the disposable stainless steel insert rod 12 in related technologies. This can effectively avoid material failures such as thread stripping, bending, torsional deformation and fatigue fracture of the insert rod 12. The handle 11 has a moderate weight, avoiding the operational errors caused by the excessively light weight of the plastic handle in related technologies.

[0095] Example 1:

[0096] As shown in Figures 1-9, the modular, separable anchor implantation system provided in this embodiment stores anchors in a storage box 2. The storage box 2 has an inlet 214 and an outlet 215 at both ends. The insertion rod 12 can be inserted into the storage box 2 through the inlet 214, allowing the insertion part 13 to engage with the anchor, and then pushing the anchor out from the outlet 215, thus completing the assembly of the inserter 1 and the anchor. Furthermore, after the inserter 1 implants the anchor, moving it in the opposite direction to the implantation direction disengages the insertion part 13 from the anchor.

[0097] Specifically, the storage box 2 is provided with an insertion channel 213. The anchor is at least partially positioned corresponding to the center line of the insertion channel 213 so that the insertion rod 12 enters the storage box 2 along the insertion channel 213. The insertion channel 213 guides the insertion rod 12. The insertion part 13 is inserted and fixed with the anchor. After the insertion rod 12 pushes the anchor out of the storage box 2, the insertion rod 12 moves to a set position and then the inserter 1 is fixed to the storage box 2 to prevent the storage box 2 from moving on the insertion rod 12 during the process of inserting the anchor through the inserter 1, which would affect the insertion of the anchor.

[0098] Of course, in other embodiments, the insertion rod 12 can be directly inserted into the storage box 2 after entering through the inlet 214, and in this case, the insertion channel 213 may not be provided in the storage box 2.

[0099] The inserter 1 of this modular suture anchor implantation system is reusable, requiring only the replacement of the storage box 2, thus reducing costs and the probability of mechanical failure. The anchors are stored separately, preventing environmental contamination of the implants during preoperative preparation and reducing surgical risks. At the same time, the storage box 2 is small in size, facilitating preoperative material preparation.

[0100] The storage box 2 includes a box body 21, an anchor clamping assembly 22, and a suture storage and winding structure. The anchor clamping assembly 22 is located inside the box body 21 and is used to clamp the anchor. After the anchor is inserted and fixed to the insertion part 13, under the pushing force of the inserter 1, the anchor can break free from the clamping force of the anchor clamping assembly 22 and be pushed out from inside the anchor clamping assembly 22. The anchor is provided with a suture hole. After the suture 200 passes through the suture hole, both ends are stored in the suture storage and winding structure. As the anchor moves out of the box body 21 under the pushing force of the inserter 1, it pulls the suture 200. The suture storage and winding structure begins to release the suture 200 until the anchor is implanted into the bone. Then, the inserter 1 moves in the opposite direction to the implantation direction, allowing the suture 200 to slide out of the box body 21 and be completely released.

[0101] In this embodiment, the anchor pins and sutures 200 are stored in the same storage box 2. Of course, in other embodiments, the anchor pins and sutures 200 can also be stored separately.

[0102] As shown in Figures 9-11, the box body 21 includes a top shell 211 and a bottom shell 212 that are snapped together. The top shell 211 and the bottom shell 212 are snapped together by a hook 2111 and a groove. After the top shell 211 and the bottom shell 212 are snapped together, a storage space is formed inside. The opposite ends of the storage space are respectively provided with an inlet 214 and an outlet 215. Anchor pins and sutures 200 are stored in the storage space. An insertion channel 213 extends along the line connecting the inlet 214 and the outlet 215. Both the inlet 214 and the outlet 215 can communicate with the insertion channel 213. The insertion rod 12 enters the storage space from the inlet 214, moves along the insertion channel 213 to be inserted into the anchor pin, and pushes the anchor pin out from the outlet 215.

[0103] Specifically, within the top shell 211 and the bottom shell 212, two protrusions are respectively arranged along their respective central symmetry lines. The two protrusions on the top shell 211 and the two protrusions on the bottom shell 212 align to form an insertion channel 213. The centerline of the anchor clamping assembly 22 and the centerline of the insertion channel 213 are on the same straight line. Thus, the insertion rod 12 enters the insertion channel 213 through the inlet 214. The insertion channel 213 provides guidance for the insertion rod 12. Under the guidance of the insertion channel 213, the insertion rod 12 can move to the anchor clamping assembly 22, ensuring that the insertion part 13 on the insertion rod 12 can be inserted and fixed with the anchor clamped in the anchor clamping assembly 22, and after insertion and fixing, the anchor is pushed out of the box 21. Two wire storage and winding structures are provided, with the two wire storage and winding structures respectively located on both sides of the anchor. This arrangement facilitates the storage and release of the two ends of the stitching 200 passing through the anchor through the two wire storage and winding structures respectively.

[0104] The outer contour of the box 21 is approximately cross-shaped. The two wing areas of the cross shape are used to accommodate the wire storage and winding structure, and the head and tail areas are used to accommodate the insertion channel 213 and the anchor clamping assembly 22, respectively.

[0105] Referring again to Figures 1 and 5, the insertion rod 12 also includes a guide boss 14 that mates with the insertion channel 213. The diameter of the insertion rod 12 is smaller than the inner diameter of the insertion channel 213. When the insertion rod 12 enters the housing 21, the guide boss 14 mates with the insertion channel 213 to guide the movement of the insertion rod 12. The guide boss 14 may be located at one end of the insertion rod 12 near the insertion portion 13.

[0106] As shown in Figures 12-14, specifically, the anchor clamping assembly 22 includes an elastic element and two symmetrically arranged clamps 222. The two clamps 222 are connected by the elastic element to form a receiving cavity 223. The inlet 214 and the outlet 215 are both connected to the receiving cavity 223, and the anchor is stored in the receiving cavity 223. The two clamps 222 are slidably disposed in the storage box 2. Under the pushing force of the insertion rod 12, the ends of the two clamps 222 near the outlet 215 of the storage box 2 slide open in a direction away from each other to push the anchor out of the storage box 2. The two grippers 222 are connected by an elastic element, so that the receiving cavity 223 formed by the two grippers 222 under the action of the elastic element can clamp the anchor. The two grippers 222 are slidably disposed in the storage box 2, so that the anchor can drive the two grippers 222 to move away from each other under the pushing force of the insertion rod 12, and the end of the two grippers 222 near the outlet 215 opens, and the insertion rod 12 pushes the anchor out of the receiving cavity 223.

[0107] In this embodiment, one end of the insertion channel 213 is connected to the inlet 214, and the other end is connected to the receiving cavity 223. That is, the insertion channel 213 extends from the inlet 214 to the receiving cavity 223. When the insertion channel 213 extends from the inlet 214 to the receiving cavity 223, there is no constraint of the protrusion forming the insertion channel 213 near the outlet 215, which facilitates the removal of the box 21 from the inserter 1; moreover, it will not interfere with the anchor clamping assembly 22, which can increase the volume of the receiving cavity 223 formed by the two clamps 222, and adapt to the clamping of larger-sized anchors.

[0108] The centerline of the receiving cavity 223 coincides with the symmetry line of the two grippers 222. That is, the anchor is placed inside the receiving cavity 223, and the axis of the anchor is located on the symmetry line of the two grippers 222. The insertion rod 12 moves along the insertion channel 213 to the insertion part 13 and inserts into the tail of the anchor. This arrangement is suitable for clamping the boss anchor 101 and the inner hole anchor 102.

[0109] The insertion part 13 is configured according to the shape of the anchor, including a prism-shaped head or an inner hole-shaped head.

[0110] For example, as shown in FIG15, the tail of the boss anchor 101 is in the shape of a hexagonal pyramid, and the insertion part 13 is configured as an inner hole head, that is, a hexagonal hole that mates with the hexagonal pyramid. The thread hole of the boss anchor 101 extends through the opposite sides of the hexagonal pyramid. At the same time, in order to facilitate the connection of the suture 200 passing through the thread hole with the thread storage and winding structure, the opposite sides of the hexagonal hole are connected.

[0111] As shown in Figures 16 and 17, the inner hole of the inner anchor 102 is a hexagonal hole, extending from the tail to the head of the inner anchor 102. A crossbar 1021 is provided near the head of the inner anchor 102. One end of the suture 200 enters through the hexagonal hole, passes through the crossbar 1021, and then returns. The insertion part 13 is configured as a prism-shaped head, that is, a hexagonal prism that mates with the hexagonal hole. Both sides of the hexagonal prism are provided with clearance grooves. Both ends of the suture 200 pass through the clearance grooves and extend from the tail of the inner anchor 102.

[0112] Referring to Figures 12 and 13, the two grippers 222 have cavities on their adjacent sides, which are joined together to form the receiving cavity 223. A limiting plane 2224 is provided at the end of the cavity near the inlet 214, and a limiting inclined surface 2225 is provided at the end near the outlet 215. The limiting plane 2224 and the limiting inclined surface 2225 together restrict the movement of the anchor pin within the receiving cavity 223, ensuring that the insertion part 13 can be smoothly inserted into the anchor pin.

[0113] Furthermore, the cavity is located in the middle of the gripper 222, and semi-circular holes are provided at both ends of the cavity. After the two grippers 222 are connected, the semi-circular holes of the two grippers 222 are connected to form a clearance hole for the insertion rod 12 to pass through.

[0114] A semi-annular groove 2223 is provided along the circumference of the gripper 222. The semi-annular grooves 2223 of the two grippers 222 are joined to form an installation groove, and an elastic element is disposed in the installation groove. The elastic element is an elastic tape 2211 adapted to the installation groove. The elastic force of the elastic tape 2211 is used to fix the two grippers 222 together to store the anchor. At the same time, after the insertion rod 12 is inserted and fixed to the anchor, it applies a greater thrust to the anchor. The anchor drives the two grippers 222 to overcome the elastic force of the elastic tape 2211, so that the ends of the two grippers 222 near the outlet 215 move away from each other. The end of the anchor clamping assembly 22 near the outlet 215 is in an open state, and the anchor pushes out of the receiving cavity 223 and slides out from the outlet 215.

[0115] Referring again to Figures 10 and 13, a slide rail 217 is provided inside the storage box 2, and a sliding post 2222 is provided on the gripper 222, which is slidably connected to the slide rail 217. When the insertion rod 12 pushes the anchor, the anchor applies a pushing force to the two grippers 222. When the two grippers 222 move away from each other against the elastic force of the elastic tape 2211, the sliding post 2222 cooperates with the slide rail 217 to guide the movement direction of the two grippers 222. This allows the two grippers 222 to return to their original shape along the slide rail 217 after the anchor is pushed out of the receiving cavity 223, under the action of the elastic restoring force of the elastic tape 2211.

[0116] Each gripper 222 has a sliding post 2222 at both ends on the same side. The slide 217 includes a first slide 2171 and a second slide 2172. The first slide 2171 is located near the inlet 214, and the second slide 2172 is located near the outlet 215. Both the first slide 2171 and the second slide 2172 extend away from the gripper 222 and closer to the outlet 215. The angle between the first slide 2171 and the line of symmetry of the two grippers 222 is smaller than the angle between the second slide 2172 and the line of symmetry of the two grippers 222. When the insertion rod 12 pushes the anchor pin, the anchor pin applies a force to the end of the gripper 222 near the outlet 215. The ends of the two grippers 222 near the outlet 215 open, and the opening angle of the end near the inlet 214 is smaller than the opening angle of the end near the outlet 215. Therefore, the angle between the first slide rail 2171 and the line of symmetry of the two grippers 222 is smaller than the angle between the second slide rail 2172 and the line of symmetry of the two grippers 222. By setting two slide rails 217, the movement path of the grippers 222 can be better controlled, ensuring the opening angle of the end of the grippers 222 near the outlet 215.

[0117] Specifically, referring to Figures 9-11, both the top shell 211 and the bottom shell 212 are provided with a first slide rail 2171 and a second slide rail 2172. Two sliding posts 2222 are provided on both sides of the gripper 222. In this way, the two sliding posts 2222 on the side of the gripper 222 closer to the top shell 211 are slidably engaged with the first slide rail 2171 and the second slide rail 2172 correspondingly provided on the top shell 211, and the two sliding posts 2222 on the side of the gripper 222 closer to the bottom shell 212 are slidably engaged with the first slide rail 2171 and the second slide rail 2172 correspondingly provided on the bottom shell 212, so as to ensure the stability and reliability of the two grippers 222 when they move.

[0118] The suture storage and winding structures are symmetrically arranged on both sides of the anchor. After the suture 200 passes through the anchor, its two ends are connected to the two suture storage and winding structures respectively. The insertion rod 12 drives the storage box 2 to move in the opposite direction to the implantation direction, and the suture storage and winding structures can automatically release the suture 200. Before the operation, the suture 200 passes through both ends of the anchor and is stored in the two suture storage and winding structures respectively. After the anchor is implanted, all the sutures 200 can be released simply by pulling the handle 11 in the opposite direction to the implantation direction, without the need to manually untie the sutures 200, further simplifying the surgical operation and improving surgical efficiency.

[0119] Specifically, as shown in Figures 18-20, the thread storage and winding structure includes a ratchet 23, which is rotatably disposed within the storage box 2. The ratchet 23 includes a central shaft 231 and two baffles 232 located at both ends of the central shaft 231. The baffles 232 are provided with spaced-apart take-up grooves 2321. The suture 200 is wound around the central shaft 231, and the tail end of the suture 200 is engaged in two adjacent take-up grooves 2321. The suture 200 is stored wound around the central shaft 231, and the tail end of the suture 200 is secured in the two adjacent take-up grooves 2321 to prevent it from unraveling. When releasing the suture 200, under the pulling force of the anchor pin, the tail end of the suture 200 can automatically break free from the take-up groove 2321 and be released, without manual untying.

[0120] The ratchet 23 can hold various types of sutures 200, such as flat ribbon sutures, flat round sutures, absorbable sutures, barbed sutures, coated sutures, and sandwich sutures. Moreover, the ratchet 23 has enough space to accommodate various sizes of sutures 200, such as 6-0, 4-0, 2-0, #2, #4, and #6.

[0121] Specifically, referring to Figures 10 and 11, both the top shell 211 and the bottom shell 212 are provided with ratchet grooves 216. The ratchet 23 is disposed in the receiving space formed by the corresponding ratchet grooves 216 of the top shell 211 and the bottom shell 212. A sleeve 2161 that rotates with the central shaft 231 is disposed at the center of the ratchet groove 216. The two ends of the central shaft 231 are respectively disposed in the sleeve 2161. When the suture 200 is subjected to the tension of the anchor, the central shaft 231 rotates relative to the sleeve 2161, thereby gradually releasing the suture 200.

[0122] Further, as shown in Figure 20, multiple elastic pawls 233 are spaced circumferentially along the baffle 232, forming an annular groove between the elastic pawls 233 and the baffle 232. Each annular groove has a suture take-up groove 2321 extending radially along the baffle 232 on its inner side. The ends of the elastic pawls 233 are provided with protruding posts 2331. During the rotation of the ratchet 23, the protruding posts 2331 contact the inner wall of the ratchet groove 216, providing a damping effect on the pulling out of the suture 200, ensuring stable pulling out of the suture 200. The multiple elastic pawls 233 provide a stable torque for the pulling out of the suture 200, ensuring the symmetry of the torque on the central axis 231. Additionally, during the rotation of the ratchet 23, the protruding posts 2331 contacting the ratchet groove 216 produce a clicking sound, which serves as a prompt, indicating to medical personnel that the suture 200 is being pulled out normally.

[0123] Referring again to Figures 10 and 11, a guide damping post 218 is also provided on the periphery of the ratchet 23. The suture 200 passing through the anchor pin wraps around the guide damping post 218 and is wound around the central shaft 231. The guide damping post 218 provides damping for the pulling and stretching action of the suture 200, reducing the low-frequency vibration generated in the gap between the elastic pawls 233 on the ratchet 23, and ensuring the consistency of the tension of the suture 200 during the release process.

[0124] Specifically, the ratchet groove 216 has a circumferential notch, and two guide damping posts 218 are located on the outside of the notch. One guide damping post 218 is located near the jaw 222 on one side of the notch, and the other is located away from the jaw 222 on the opposite side of the notch. The suture 200 passing through the anchor first goes around the guide damping post 218 near the jaw 222, then around the guide damping post 218 away from the jaw 222, and then enters the ratchet groove 216 through the notch, where it wraps around the central shaft 231. This arrangement ensures that the suture 200 maintains a certain tension during the release process.

[0125] As shown in Figures 21 and 22, to ensure the stability of the engagement between the handle 11 and the storage box 2, a spherical groove 2121 is provided on the storage box 2. A positioning bead 112 is provided on one side of the bayonet 111. The positioning bead 112 can cooperate with the spherical groove 2121 to fix the inserter 1 and the storage box 2. A through hole is provided on one side of the bayonet 111, and the positioning bead 112 is installed in the through hole. The positioning bead 112 is a ball-head plunger composed of a housing, a spring, a ball or a cylinder. Under pressure, the ball retracts into the housing. When the ball is opposite to the spherical groove 2121, the ball extends under the elastic restoring force of the spring and cooperates with the spherical groove 2121, thereby fixing the storage box 2.

[0126] Specifically, spherical grooves 2121 are provided on the outer surface of the bottom shell 212, and three are provided at intervals along the center line of the bottom shell 212. One positioning bead 112 is provided. The positioning bead 112 only needs to cooperate with one of the spherical grooves 2121 to fix the storage box 2.

[0127] The structural design of the storage box 2 provided in this embodiment transforms a simple insertion action into a programmed, precise mechanical action. During the insertion process, it completes mechanical actions such as nail removal, suture placement, and tensioning of the suture 200, as well as anchor implantation in conjunction with the handle 11. The anchor clamping assembly 22 is configured as two symmetrical sliding jaws 222 that cooperate with the insertion channel 213. The jaws 222 clamp the anchor using an elastic tape 2211. After the anchor is pushed up by the insertion rod 12 at the end of the two jaws 222 near the inlet 214, the end near the outlet 215 opens to release the anchor. During the release process, it is constrained by the elastic tape 2211. Through simple structural improvements, the anchor clamping assembly 22 can be adapted to any type of anchor. The ratchet 23 and guide damping post 218 on both sides of the anchor clamping assembly 22 can semi-automatically manage the suture 200, releasing the suture 200 of a set length as needed. The guide damping post 218 is used to ensure that the suture 200 released from the ratchet 23 is released in a taut state. When the suture 200 is stored in the box 21, it is in the shape of an "M" with a ring at the end. This storage box 2 can realize the individual packaging of anchors and can be used with the reusable inserter 1 to realize the assembly of anchors and inserters 1. It is small in size and allows for the preparation of a sufficient number and variety of storage boxes 2 before surgery to ensure the response to emergencies during surgery.

[0128] The inserter 1 provided in this embodiment is a reusable surgical tool. It allows for a reasonable increase in cost to enhance structural strength and improve the stability of the mechanical structure. The inserter 1 allows for quick replacement of the insertion rod 12, which is fixed to the storage box 2 via the positioning bead 112 on the handle 11. Both the insertion rod 12 and the insertion part 13 are made of hard stainless steel, ensuring the quality of the insertion rod 12 and reducing the frequency of intraoperative instrument failure caused by quality issues with the inserter 1.

[0129] As shown in Figures 23-30, the method of using the split modular wire anchor implantation system provided in this embodiment is as follows:

[0130] (1) Hold the handle 11 of the inserter 1 with one hand and the storage box 2 with the other hand.

[0131] (2) Insertion rod 12 enters the box body 21 from the inlet 214 of the storage box 2 and moves along the insertion channel 213. When the insertion part 13 moves to align with the tail of the anchor, the insertion rod 12 is pushed further and the insertion part 13 is inserted into the anchor. At the same time, the insertion rod 12 and the anchor push the clamp 222. The clamp 222 moves along the slide 217 and the two clamps 222 overcome the constraint of the elastic tape 2211, causing the elastic tape 2211 to undergo elastic deformation. The end of the two clamps 222 near the outlet 215 is in an open state, and the anchor is pushed out from the receiving cavity 223. During the movement of the anchor, the suture 200 is subjected to tension and drives the ratchet 23 to rotate through the guide damping column 218. The ratchet 23 begins to release the suture.

[0132] (3) The insertion rod 12 continues to move, the anchor pushes forward and slides out of the box 21 through the outlet 215, the gripper 222 no longer slides, under the action of the elastic restoring force of the elastic tape 2211, the two grippers 222 move towards each other until they fit with the insertion rod 12 and the suture 200, the anchor drives the suture 200 to continue to move, and drives the ratchet 23 to continue to rotate.

[0133] (4) Insert rod 12 pushes the box 21 forward, ratchet 23 continues to rotate to feed the line, insert rod 12 continues to move until box 21 blocks handle 11 and can no longer move, positioning bead 112 at the bayonet 111 of handle 11 cooperates with spherical groove 2121 to fix the relative position of box 21 and handle 11.

[0134] (5) By turning the handle 11 to implant the anchor into the bone, the suture 200 can be released.

[0135] (6) When releasing the suture 200, the head of the suture 200 is fixed at the tail of the anchor. Pull the handle 11 in the opposite direction to the implantation direction, and the box 21 moves away from the anchor. The suture 200 drives the ratchet 23 to rotate, and the suture 200 is gradually released. During the release of the suture 200, the guide damping column 218 keeps the suture 200 under a certain tension during the pulling process.

[0136] (7) The inserter 1 continues to move in the opposite direction to the implantation direction, and the ratchet 23 continues to rotate to release the suture until the end of the suture 200 breaks free from the take-up groove 2321 and slides out of the box 21, and the release of the suture 200 is completed.

[0137] (8) After the suture 200 is released, the box 21 can be removed from the insertion rod 12.

[0138] After one anchor is implanted, when implanting the next anchor, the inserter 1 is assembled with the next storage box 2, and the above steps are followed to continue implanting the next anchor. This cycle continues until the implantation is complete.

[0139] Example 2:

[0140] This embodiment provides a separate modular wire anchor implantation system, which shares the same working principle and structure of most components as the separate modular wire anchor implantation system provided in Embodiment 1. The similarities will not be repeated here. The main differences lie in the structure of the insertion channel 213, the structure of the anchor clamping assembly 22, the wire storage and winding structure, and the fixing structure between the handle 11 and the storage box 2.

[0141] As shown in Figures 31-36, the insertion channel 213 is configured as a through-type channel, with one end connected to the inlet 214 and the other end connected to the outlet 215. That is, the insertion channel 213 extends from the inlet 214 to the outlet 215. The anchor clamping assembly 22 is disposed on the protrusion, and the height of the protrusion between the anchor clamping assembly 22 and the inlet 214 is higher than the height of the protrusion below the anchor clamping assembly 22, so as to ensure that the center line of the anchor clamping assembly 22 and the center line of the insertion channel 213 are on the same straight line, which improves the stability when the insertion rod 12 is inserted into the box 21 and pushes out the anchor. The rotation direction is constrained throughout the entire pushing process of the insertion rod 12.

[0142] Specifically, the height of the protrusion between the anchor clamping assembly 22 and the inlet 214 on the bottom shell 212 is higher than the height of the protrusion below the anchor clamping assembly 22. The protrusion on the top shell 211 extends from the inlet 214 to the anchor clamping assembly 22.

[0143] Furthermore, the connection between the inlet 214 and the insertion channel 213 is designed in a funnel shape to facilitate the insertion rod 12 to enter more smoothly.

[0144] Specifically, the anchor clamping assembly 22 has two jaws 222, each with a sliding post 2222 on the same side. The slide rail 217 extends away from the jaws 222 and closer to the outlet 215. Each jaw 222 has a sliding post 2222 on the same side. When the jaws 222 move, a sliding post 2222 is provided on each side of the jaws 222, respectively engaging with the slide rail 217 on the top shell 211 and the bottom shell 212 for sliding.

[0145] Furthermore, an elastic element is arranged around the sliding posts 2222 that are oppositely arranged on the two grippers 222. The sliding post 2222 includes a post body and a sliding head. The outer diameter of the sliding head is larger than the outer diameter of the post body. The sliding head slides within the slide rail 217. The elastic element is an elastic rubber ring 2212, which is engaged between the sliding head and the sidewalls of the grippers 222. This arrangement allows the grippers 222 to open at a larger angle when releasing the anchor, thus accommodating larger anchors. One elastic rubber ring 2212 can be provided, meaning one side of each gripper 222 is constrained by the elastic rubber ring 2212; or two elastic rubber rings 2212 can be provided, meaning both sides of each gripper 222 are constrained by the elastic rubber ring 2212.

[0146] The wire storage and winding structure includes a winding groove 2191 and a take-up hole 2192. The winding grooves 2191 are symmetrically arranged on the outer periphery of the storage box 2, and one of the winding grooves 2191 has a wire passage hole 2193. The take-up holes 2192 are symmetrically arranged on the outer periphery of the storage box 2 and communicate with the interior of the storage box 2. The suture 200 passing through the anchor pin passes through the wire passage hole 2193 and is wound around the oppositely arranged winding groove 2191. The tail end of the suture 200 is inserted into the oppositely arranged take-up hole 2192. The lines of symmetry of the winding groove 2191 and the take-up hole 2192 are both perpendicular to the center line of the insertion channel 213. This arrangement allows the suture 200 passing through the anchor pin to exit the box body 21 from the wire passage hole 2193, wrap around the winding groove 2191 on the surface of the box body 21, and after wrapping around the winding groove 2191 several times, it is then wrapped around the take-up hole 2192 for fixation. The suture 200 on the winding groove 2191 needs to be manually untied to be released. When the anchor cannot be pushed out by the insertion rod 12, the suture 200 will be released automatically.

[0147] Furthermore, the wire storage and winding structure also includes a wire storage groove 2194, which is located inside the storage box 2. The suture 200 is confined within the wire storage groove 2194. The suture 200, after passing through the anchor, is led out through the wire storage groove 2194 and then through the wire passage hole 2193. After passing through the anchor, the suture 200 enters the internal wire storage groove 2194, is stacked several times, and then is led out from the wire storage groove 2194 and passes through the wire passage hole 2193. This part stores the suture 200 inside the box 21. The wire storage groove 2194 compresses and fixes the suture 200 stored inside the box 21. When the anchor is pushed out, the suture 200 in the wire storage groove 2194 has a certain resistance under the compressive force.

[0148] Specifically, the wire storage groove 2194 is formed by three spaced rectangular protrusions between two opposing vertical plates on the bottom shell 212 or top shell 211. Each of the three rectangular protrusions has a gap between its two sides and the two vertical plates to form a U-shaped groove. Each rectangular protrusion has a limiting plate at its upper end. The limiting plate on the middle rectangular protrusion is connected to the first vertical plate and spaced apart from the second vertical plate. The limiting plates on the rectangular protrusions on both sides are connected to the second vertical plate and spaced apart from the first vertical plate. The gap between the limiting plates and the vertical plates is smaller than that between the rectangular protrusions, thus pressing the suture 200 to prevent it from coming out. After the suture 200 is stacked several times within the U-shaped groove, it is pressed by the limiting plates and then led out from the U-shaped groove.

[0149] Of course, in other embodiments, the storage groove 2194 can also be configured as a serpentine limiting groove, with the suture 200 stored around the serpentine limiting groove.

[0150] Furthermore, the length of the suture 200 stored inside the box 21 is equal to the length of the insertion rod 12. When the insertion rod 12 pushes the anchor to the limit position, the suture 200 in the suture storage groove 2194 is completely released.

[0151] Furthermore, the wire storage and winding structure also includes a tensioning element 2195, which is located between the anchor and the wire storage groove 2194. The suture 200 passing through the anchor is tensioned by the tensioning element 2195 and then enters the wire storage groove 2194. The tensioning element 2195 includes a guide plate and a guide post. The guide plate is located outside the first plate and is set at an angle to the first plate. One end of the guide plate is connected to the first plate, and the other end is connected to the guide post. The suture 200 passing through the anchor bypasses the guide post and is guided into the wire storage groove 2194 by the guide plate. The limiting plate squeezes the suture 200. When the suture 200 is released, the guide post and the guide plate can ensure that the suture 200 in the wire storage groove 2194 maintains a certain tension when released.

[0152] The inserter 1 provided in this embodiment has a latching member 113 on one side of the latch 111 of the handle 11. The latching member 113 is rotatably connected to the handle 11 and is used to clamp the storage box 2 by cooperating with the other side wall of the latch 111. Pressing one end of the latching member 113 allows the other end of the latching member 113 to move away from the other side wall of the latch 111. The clamping member is a rocker gripper, which is rotatably connected to the handle 11 via a pivot. One end of the rocker gripper is provided with a pressing part 1132. Pressing the pressing part 1132 allows the other end of the rocker gripper to move away from the other side wall of the latch 111, thereby releasing the storage box 2 and removing it.

[0153] Specifically, the storage box 2 is provided with multiple slots 2122, and the other end of the snap-fit ​​component 113 is provided with multiple snap protrusions 1131, which engage with the slots 2122. The snap protrusions 1131 are designed with trapezoidal teeth, which greatly increases the connection strength between the storage box 2 and the handle 11 and prevents the storage box 2 from accidentally falling off. After use, the storage box 2 can be disassembled by pressing the pressing part 1132.

[0154] Example 3:

[0155] This embodiment provides a separate modular wire anchor implantation system, which shares the same working principle and structure of most components as the separate modular wire anchor implantation system provided in Embodiment 1. The similarities will not be repeated here. The main differences lie in the structure of the insertion part 13 and the structure of the anchor clamping assembly 22.

[0156] As shown in Figures 37-44, the modular suture anchor implantation system provided in this embodiment uses a flexible suture anchor 103 with a flattened center. The suture anchor 103 is stored horizontally. The insertion part 13 includes an insertion rod 131 and a fork-shaped head 1311. The fork-shaped head 1311 is located at the end of the insertion rod 131 away from the insertion rod 12. After the fork-shaped head 1311 clamps the flattened structure in the center of the suture anchor 103, a force is applied to the suture anchor 103 through the insertion rod 12, causing the suture anchor 103 to deform and form a V-shape when pushed out of the storage box 2. The structure of the insertion part 13 and the anchor clamping assembly 22 have been improved based on the structure of the suture anchor 103.

[0157] The anchor clamping assembly 22 provided in this embodiment has a center line of receiving cavity 223 that is perpendicular to the symmetry line of the two clamping jaws 222. The connection between the two clamping jaws 222 also forms a through hole 224 whose center line coincides with the symmetry line of the two clamping jaws 222. The through hole 224 is used for the insertion rod 12 to pass through. That is, the structure of the clamping jaws 222 is modified according to the structure of the full-stitch anchor 103, so that the storage box 2 is also suitable for storing the full-stitch anchor 103.

[0158] Furthermore, in order to facilitate the easier ejection of the horizontally positioned full-stitch anchor 103 from the anchor clamping assembly 22 by the insertion rod 12, the end of the gripper 222 near the outlet 215 of the storage box 2 is configured as an opening 2221, and the receiving cavity 223 communicates with the opening 2221.

[0159] As shown in Figures 39-43, the full-suture anchor 103 is placed horizontally in the receiving cavity 223. The suture 200 extends from both ends of the full-suture anchor 103 and connects to the suture storage and winding structures on both sides. The insertion rod 12 enters the box 21 through the through hole 224 and moves until the fork-shaped head 1311 clamps the flat structure in the middle of the full-suture anchor 103. As it continues to move, the middle of the full-suture anchor 103 deforms into a forward-protruding shape. The grippers 222 gradually open under the pressure of this forward-protruding shape. The insertion rod 12 continues to move, and the full-suture anchor 103 continues to move, being compressed into an approximately V-shape. After the grippers 222 have opened to a sufficient angle so that the full-suture anchor 103 can pass through, the angle no longer expands further under the action of the elastic tape 2211. The ratchet 23 begins to rotate under the pull of the suture 200. The insertion rod 12 continues to move, and the full-suture anchor 103 can completely disengage from the opening 2221 and be ejected from the box 21.

[0160] When implanting the full suture anchor 103, the end of the handle 11 needs to be tapped to drive the full suture anchor 103 into the predetermined position and depth. Then, the insertion rod 12 can be pulled out by holding the handle 11 in the opposite direction to the implantation direction. The ratchet 23 rotates to release the suture 200. After the suture 200 is released, the implantation is complete. The box 21 can then be removed from the insertion rod 12.

[0161] As shown in Figure 44, the insertion rod 131 is also equipped with a stress relief platform 1312 and a marking line 1313, with the marking line 1313 positioned between the stress relief platform 1312 and the insertion rod 12. The stress relief platform 1312 serves to reduce the compressive contact stress during impact implantation. The marking line 1313 indicates the implantation depth during the procedure. The diameter of the insertion rod 131 is smaller than that of the insertion rod 12, reducing the interference at the interface between the bone, the insertion rod 131, and the anchor caused by impact implantation.

For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of this application. The content of this specification should not be construed as a limitation of this application.
