Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a separable modular suture - threaded anchor implant system. Background Art

[0002] Anchors are widely used for the fixation of bone and soft tissue. Around the shoulder, knee, hip, elbow, wrist and ankle, etc., using the anchor and suture, the soft tissue (such as tendons and ligaments) can be simply and effectively fixed to the bone, and its position can be maintained without loosening or excessive tension until healing.

[0003] In the existing bone anchor implant system, the inserter is pre - assembled with the anchor and suture as a whole. During the operation, the inserter, the anchor and the suture need to be used in a set. This makes the inserter directly discarded after the operation. In actual surgery, the number and type of anchors will be selected according to actual needs, which results in multiple inserters being discarded in one operation. The inserter cannot be reused, which not only wastes medical resources and pollutes the environment, but also is not conducive to surgical operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a separable modular suture - threaded anchor implant system to achieve the separate storage of the anchor and the suture, and at the same time achieve the free assembly of the anchor and the inserter. The inserter can be reused, reducing the waste of medical resources and simplifying the surgical operation.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The separable modular suture - threaded anchor implant system includes:

[0007] An inserter, including an insertion rod, and a plug - in part is provided at the head of the insertion rod;

[0008] A storage box, in which an anchor is stored. An inlet and an outlet are respectively provided at both ends of the storage box. The insertion rod can be inserted into the storage box through the inlet, so that the plug - in part is inserted into the anchor, and the anchor is pushed out from the outlet to complete the assembly of the inserter and the anchor; and after the inserter implants the anchor, moving in the direction opposite to the implantation direction can make the plug - in part disconnect from the anchor.

[0009] As an alternative solution of the separable modular wire - attached anchor implant system, an anchor clamping assembly is arranged in the storage box. The anchor clamping assembly includes an elastic member and two symmetrically arranged clamping jaws. The two clamping jaws are connected by the elastic member to form a receiving cavity. Both the inlet and the outlet communicate with the receiving cavity, and the anchor is stored in the receiving cavity. The two clamping jaws are both slidably arranged in the storage box. Under the thrust of the insertion rod, the ends of the two clamping jaws close to the outlet slide and open in a direction away from each other to push the anchor out of the storage box.

[0010] As an alternative solution of the separable modular wire - attached anchor implant system, the central line of the receiving cavity coincides with the symmetry line of the two clamping jaws.

[0011] Or, the central line of the receiving cavity is perpendicular to the symmetry line of the two clamping jaws. After the two clamping jaws are connected, a through - hole with a central line coinciding with the symmetry line of the two clamping jaws is further formed, and the through - hole is used for the insertion rod to pass through.

[0012] As an alternative solution of the separable modular wire - attached anchor implant system, a slideway is arranged in the storage box, and sliding columns slidably connected to the slideway are arranged on the clamping jaws.

[0013] Sliding columns are arranged at both ends of the same side of each clamping jaw. The slideway includes a first slideway and a second slideway. The first slideway is arranged close to the inlet, and the second slideway is arranged close to the outlet. Both the first slideway and the second slideway extend in a direction away from the clamping jaws and close to the outlet. The included angle between the first slideway and the symmetry line of the two clamping jaws is smaller than the included angle between the second slideway and the symmetry line of the two clamping jaws.

[0014] Or, one sliding column is arranged on the same side of each clamping jaw, and the slideway extends in a direction away from the clamping jaws and close to the outlet.

[0015] As an alternative solution of the separable modular wire - attached anchor implant system, a semi - circular groove is arranged along the circumferential direction of the clamping jaw. The semi - circular grooves of the two clamping jaws are butted to form a mounting groove, and the elastic member is arranged in the mounting groove.

[0016] Or, the elastic member is arranged around the sliding columns oppositely arranged on the two clamping jaws.

[0017] As an alternative solution of the separable modular wire - attached anchor implant system, an insertion channel is further arranged in the storage box. The central line of the anchor clamping assembly and the central line of the insertion channel are located on the same straight line. One end of the insertion channel communicates with the inlet, and the other end communicates with the receiving cavity or the outlet.

[0018] As an alternative of the separable modular wire - carrying anchor implanting system, a suture is also stored in the storage box. Storage and winding structures for the suture are symmetrically arranged on both sides of the anchor. After the suture passes through the anchor, its two ends are respectively connected to the two storage and winding structures. The insertion rod drives the storage box to move in a direction opposite to the implanting direction, and the storage and winding structure can release the suture.

[0019] As an alternative of the separable modular wire - carrying anchor implanting system, the storage and winding structure for the suture includes a ratchet wheel which is rotatably arranged in the storage box. The ratchet wheel includes a central shaft and two baffles arranged at both ends of the central shaft. Grooves for winding the suture are arranged at intervals on the baffles. The suture is wound around the central shaft, and the tail end of the suture is stuck in adjacent two of the grooves for winding the suture.

[0020] As an alternative of the separable modular wire - carrying anchor implanting system, a plurality of elastic pawls are arranged at intervals along the circumferential direction of the baffle. An annular groove is formed between the elastic pawl and the baffle, and a groove for winding the suture extending radially along the baffle is arranged inside each annular groove.

[0021] As an alternative of the separable modular wire - carrying anchor implanting system, a guiding damping column is also arranged on the circumferential side of the ratchet wheel. The suture passing through the anchor bypasses the guiding damping column and is wound around the central shaft.

[0022] As an alternative of the separable modular wire - carrying anchor implanting system, the storage and winding structure for the suture includes a groove for winding the suture and a hole for winding the suture. The grooves for winding the suture are symmetrically arranged on the outer periphery of the storage box. One of the grooves for winding the suture is provided with a wire - passing hole. The holes for winding the suture are symmetrically arranged on the outer periphery of the storage box and are communicated with the inside of the storage box. The suture passing through the anchor passes through the wire - passing hole and is wound in the relatively - arranged grooves for winding the suture, and the tail end of the suture is stuck in the relatively - arranged holes for winding the suture;

[0023] The symmetry lines of the grooves for winding the suture and the holes for winding the suture are both perpendicular to the connection line between the inlet and the outlet.

[0024] As an alternative of the separable modular wire - carrying anchor implanting system, the storage and winding structure for the suture further includes a storage groove for the suture which is arranged in the storage box. The suture can be limited in the storage groove for the suture. The suture passing through the anchor is led out through the storage groove for the suture and then passes through the wire - passing hole.

[0025] As an alternative of the separable modular wire - carrying anchor implant system, the wire storage and winding structure further includes a tensioning member disposed between the anchor and the wire storage groove, and the suture passing through the anchor enters the wire storage groove after being tensioned by the tensioning member.

[0026] As an alternative of the separable modular wire - carrying anchor implant system, the inserter further includes a handle. One end of the handle is provided with a bayonet, the insertion rod extends into the bayonet and is detachably connected to the handle, and the bayonet is used for clamping the storage box.

[0027] As an alternative of the separable modular wire - carrying anchor implant 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.

[0028] As an alternative of the separable modular wire - carrying anchor implant system, a clamping member is provided on one side of the bayonet. The clamping member is rotatably connected to the handle and is used to cooperate with the other side wall of the bayonet to clamp the storage box. Pressing one end of the clamping member, the other end of the clamping member can move away from the other side wall of the bayonet.

[0029] As an alternative of the separable modular wire - carrying anchor implant system, the storage box is provided with a plurality of slots, and the other end of the clamping member is provided with a plurality of clamping protrusions, and the clamping protrusions are engaged with the slots.

[0030] As an alternative of the separable modular wire - carrying anchor implant system, the plugging part includes a prismatic head, an inner - hole head or a fork - shaped head.

[0031] As an alternative of the separable modular wire - carrying anchor implant system, the plugging part includes a plugging rod. The diameter of the plugging rod is smaller than that of the insertion rod. A stress - releasing platform and a marking line are provided on the plugging rod, and the marking line is disposed between the stress - releasing platform and the insertion rod.

[0032] As an alternative of the separable modular wire - carrying anchor implant system, a guiding boss is provided on the insertion rod.

[0033] As an alternative of the separable modular wire - carrying anchor implant system, the storage box includes a box body, and the box body includes a top shell and a bottom shell which are connected by clamping.

[0034] Advantages of the present invention:

[0035] The separable modular suture - attached anchor implant system provided by the present invention stores the anchor and the suture in a storage box. On the one hand, it realizes the separate storage of the anchor and the suture. On the other hand, the storage box assembles the anchor and the suture onto the inserter. During use, only the storage box needs to be replaced, and there is no need to replace the inserter supporting it, achieving the purpose of the reusable inserter. Compared with the prior art where the anchor and the inserter are assembled one - to - one, and when replacing the anchor during use, the inserter must be replaced simultaneously, for the separable modular suture - attached anchor implant system of the present invention, firstly, the inserter can be reused, reducing unnecessary medical waste, saving medical resources, and being beneficial to environmental protection. Secondly, the anchor and the inserter are separately arranged, and the storage box is suitable for storing various anchors. If it is found during the operation that the size or type of the originally planned anchor is not suitable, only by replacing the storage box can the material replacement after the adjustment of the surgical plan be quickly completed. Therefore, during the operation, according to the actual surgical needs, only by replacing the storage box can the selection of the anchor be realized, which not only simplifies the surgical operation but also can adapt to complex and changeable surgical scenarios. In addition, since the anchor and the suture are stored in the storage box and are assembled with the insertion rod only during the operation, the risk of the anchor being exposed and contaminated during the preoperative preparation process is avoided. And the anchor clamping component in the storage box fully restricts the movement freedom of the anchor, avoiding the anchor from being misaligned, detached or stuck. At the same time, the suture in the storage box can be automatically released after implantation through the suture storage and winding structure, and the tension can be automatically adjusted during the release process. The suture is released in an orderly manner without the risk of entanglement, and there is no need for the doctor to manually untie the suture or make additional adjustments, significantly reducing the steps and operation time.

[0085] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0086] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0087] Unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0088] Unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0089] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0090] As Figures 1 - 44 shown, the embodiment of the present invention provides a separable modular wire - carrying anchor implant system, including an inserter 1 and a storage box 2. The storage box 2 stores an anchor and a suture 200. The anchor and the suture 200 can be stored in one storage box 2, or can be stored in different storage boxes 2 respectively. During the implantation operation, the inserter 1 is inserted into the storage box 2 to assemble with the anchor. After using the inserter 1 to push the anchor out of the storage box 2, the inserter 1 is fixed to the storage box 2. After realizing the assembly of the inserter 1 and the anchor, the anchor is implanted into the bone by using the inserter 1. Then, a force is applied to the inserter 1 in the direction opposite to the implantation direction to disconnect the inserter 1 from the anchor, and the suture 200 is released, which simplifies the surgical operation and improves the surgical efficiency. Finally, the storage box 2 is detached from the inserter 1; the inserter 1 can be reused, and only the storage box 2 needs to be replaced, solving the problems of resource waste and environmental pollution caused by the fact that the anchor and the inserter 1 must be used in a set in the prior art and the inserter 1 is a disposable product; at the same time, the inserter 1 can be reused, which can ensure the structural strength while saving costs, and reduces the frequency of intraoperative instrument failure caused by the quality problems of the inserter 1. Storing the anchor and the suture 200 separately in the storage box 2 can prevent the anchor from being exposed during the preoperative preparation process, being polluted by the environment, and reducing the surgical risk. Moreover, the volume of the storage box 2 is small, allowing a sufficient number and types of storage boxes 2 to be prepared before the operation to ensure the response to intraoperative emergencies.

[0091] The separable modular wire - carrying anchor implant system provided by the present invention is applicable to the implantation of anchors of various materials and various shapes. Exemplarily, 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 shapes of the boss anchor 101 and the inner - hole anchor 102.

[0092] 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 for clamping the storage box 2. Force is applied to the insertion rod 12 through the handle 11 to insert the insertion rod 12 into the storage box 2 to push out the anchor bolt, and force is applied to the anchor bolt through the handle 11 during the implantation of the anchor bolt. The head of the insertion rod 12 is provided with a plug-in portion 13, and the plug-in portion 13 is inserted into the anchor bolt. Different plug-in portions 13 are adapted according to different materials and shapes of the anchor bolts.

[0093] Exemplarily, for the full suture anchor bolt 103 and the percussion implantation anchor bolt, a hammer head is used to strike the tail of the handle 11 to strike the anchor bolt into a predetermined position and depth, and the striking action stops immediately. Then, hold the handle 11 of the inserter 1 and pull it out in the direction opposite to the implantation direction. The storage box 2 releases the suture 200. When the suture 200 is completely removed from the storage box 2, the implantation is completed.

[0094] The end of the insertion rod 12 away from the plug connector is provided with an external thread. The center of the bottom of the bayonet 111 is provided with a threaded hole 115. The insertion rod 12 extends into the threaded hole 115 and is screwed to the handle 11, so that the insertion rod 12 can be quickly replaced. For anchor bolts of different materials and shapes, different types and specifications of insertion rods 12 can be replaced. The plug-in portion 13 is welded to the insertion rod 12, which has a guiding and matching function, and at the same time ensures the reliability of the connection between the plug-in portion 13 and the insertion rod 12, avoiding the situation that when force is applied in the direction opposite to the implantation direction and the inserter 1 is disconnected from the anchor bolt, the plug-in portion 13 is disconnected from the insertion rod 12, resulting in a medical accident where the plug-in portion 13 remains in the bone.

[0095] Furthermore, one end of the handle 11 away from the bayonet 111 is provided with a weight reduction cavity 114 for reducing the overall weight of the inserter 1.

[0096] Since the inserter 1 is a reusable surgical tool, the cost of the key parts of the inserter 1 can be appropriately increased to ensure quality and improve mechanical stability. The insertion rod 12 and the plug-in portion 13 are both machined from hard stainless steel, and the strength is much higher than that of the disposable stainless steel insertion rod 12 in the prior art, which can effectively avoid material failure situations such as thread slipping, rod bending, torsion deformation, and fatigue fracture of the insertion rod 12. The weight of the handle 11 is moderate, avoiding operation errors caused by the too light weight of the plastic handle in the prior art.

[0097] Embodiment 1:

[0098] As Figures 1 - 9As shown in the figure, in the detachable modular wire - attached anchor implant system provided in this embodiment, the storage box 2 stores anchors. The two ends of the storage box 2 are respectively provided with an inlet 214 and an outlet 215. The insertion rod 12 can be inserted into the storage box 2 through the inlet 214, so that the insertion part 13 is inserted and matched with the anchor, and the anchor is pushed out from the outlet 215 to complete the assembly of the inserter 1 and the anchor. And after the inserter 1 implants the anchor, moving in the direction opposite to the implantation direction can make the insertion part 13 disconnect from the anchor.

[0099] Specifically, an insertion channel 213 is provided in the storage box 2, and at least part of the anchor is arranged 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 plays a guiding role for the insertion rod 12. The insertion part 13 is inserted and fixed with the anchor. And after the insertion rod 12 pushes the anchor out of the storage box 2, when the insertion rod 12 moves to a set position, the inserter 1 is fixed with the storage box 2 to avoid the storage box 2 moving on the insertion rod 12 during the process of implanting the anchor through the inserter 1, which affects the implantation of the anchor.

[0100] Of course, in other embodiments, after the insertion rod 12 enters the storage box 2 through the inlet 214, it can directly be inserted and matched with the anchor. In this case, the insertion channel 213 may not be provided in the storage box 2 either.

[0101] The inserter 1 of the detachable modular wire - attached anchor implant system can be reused. Only the storage box 2 needs to be replaced, which reduces the cost and the probability of mechanical failure; the anchors are stored separately. During the implantation operation, it can avoid the implant being polluted by the environment during the preoperative preparation, reducing the surgical risk; at the same time, the volume of the storage box 2 is small, which is convenient for preoperative material preparation.

[0102] The storage box 2 includes a box body 21, an anchor clamping assembly 22 and a storage and winding structure for the wire. The anchor clamping assembly 22 is arranged in the box body 21 and is used for clamping the anchor. And after the anchor is inserted and fixed with the insertion part 13, under the thrust of the inserter 1, the anchor can break free from the clamping force of the anchor clamping assembly 22 and be pushed out from the anchor clamping assembly 22. A threading hole is provided on the anchor. After the suture 200 passes through the threading hole, both ends are stored in the storage and winding structure. During the process that the anchor moves and is pushed out of the box body 21 under the thrust of the inserter 1, the suture 200 is pulled, and the storage and winding structure starts to release the suture 200. Until after the anchor is implanted into the bone, when the inserter 1 moves in the direction opposite to the implantation direction, the suture 200 can slide out of the box body 21 and be completely released.

[0103] In this embodiment, the anchor and the suture 200 are stored in the same storage box 2. Of course, in other embodiments, the anchor and the suture 200 can also be stored separately.

[0104] Such as Figures 9 - 11As shown, the box body 21 includes a top shell 211 and a bottom shell 212 that are snap-connected. The top shell 211 and the bottom shell 212 are snap-fastened. The top shell 211 and the bottom shell 212 are snap-connected through the cooperation of hooks 2111 and grooves. After the top shell 211 and the bottom shell 212 are snap-fastened, a storage space is formed inside them. Relative ends of the storage space are respectively provided with an inlet 214 and an outlet 215. The anchor and suture 200 are stored in the storage space. The insertion channel 213 extends along the connection line of 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, and pushes the anchor out from the outlet 215.

[0105] Specifically, inside the top shell 211 and the bottom shell 212, two rib strips are respectively arranged with their respective central symmetry lines as the center lines. The two rib strips on the top shell 211 and the two rib strips on the bottom shell 212 are butted to form the insertion channel 213. The central line of the anchor clamping assembly 22 and the central line of the insertion channel 213 are on the same straight line. In this way, 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 guiding action 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 pushing out the anchor from the box body 21 after the insertion and fixation. There are two wire storage and winding structures, and the two wire storage and winding structures are respectively arranged on both sides of the anchor. Such a setting facilitates the storage and release of the two ends of the suture 200 passing through the anchor respectively through the two wire storage and winding structures.

[0106] The outer contour of the box body 21 is approximately cross-shaped. The two wings of the cross are used to accommodate the wire storage and winding structures, and the head and tail areas are respectively used to accommodate the insertion channel 213 and the anchor clamping assembly 22.

[0107] Continue to refer to Figure 1 and Figure 5 , the insertion rod 12 further includes a guiding boss 14 that cooperates 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 box body 21, the guiding boss 14 cooperates with the insertion channel 213 to provide guidance for the movement of the insertion rod 12. The guiding boss 14 can be arranged at one end of the insertion rod 12 close to the insertion part 13.

[0108] As Figures 12 - 14As shown, specifically, the anchor clip assembly 22 includes an elastic member and two symmetrically arranged jaws 222. The two jaws 222 are connected by the elastic member to form a receiving cavity 223. The inlet 214 and the outlet 215 are both in communication with the receiving cavity 223. The anchor is stored in the receiving cavity 223. The two jaws 222 are both slidably disposed in the storage box 2. Under the thrust of the insertion rod 12, the ends of the two jaws 222 close to the outlet 215 of the storage box 2 slide away from each other to push the anchor out of the storage box 2. Connecting the two jaws 222 by the elastic member enables the receiving cavity 223 formed by the two jaws 222 under the action of the elastic member to clamp the anchor. The two jaws 222 are both slidably disposed in the storage box 2, so that the anchor can drive the two jaws 222 to move away from each other under the thrust of the insertion rod 12, and the ends of the two jaws 222 close to the outlet 215 open, and the insertion rod 12 pushes the anchor out of the receiving cavity 223.

[0109] In this embodiment, one end of the insertion channel 213 is in communication with the inlet 214, and the other end is in communication with 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 rib forming the insertion channel 213 at the position close to the outlet 215, which is convenient for the box body 21 to be disassembled from the inserter 1. Moreover, it will not interfere with the anchor clip assembly 22, and the volume of the receiving cavity 223 formed by the two jaws 222 can be increased to adapt to the clamping of larger-sized anchors.

[0110] The center line of the receiving cavity 223 coincides with the symmetry line of the two jaws 222. That is, the anchor is placed in the receiving cavity 223, and the axis of the anchor is located on the symmetry line of the two jaws 222. The insertion rod 12 moves along the insertion channel 213 until the insertion portion 13 is inserted into the tail of the anchor. Such a setting method is applicable to the clamping of the boss anchor 101 and the inner hole anchor 102.

[0111] The insertion portion 13 is set according to the shape of the anchor, including a prismatic head or an inner hole head.

[0112] Exemplarily, as Figure 15 shown, the tail of the boss anchor 101 is in the shape of a hexagonal pyramid, and the insertion portion 13 is set as an inner hole head, that is, a hexagonal hole matching the hexagonal pyramid. The threading hole of the boss anchor 101 penetrates through the opposite sides of the hexagonal pyramid. At the same time, in order to facilitate the suture 200 passing through the threading hole to be connected to the wire storage and winding structure, the opposite sides of the hexagonal hole are in communication.

[0113] As Figure 16 and Figure 17As shown, the inner hole of the internal hole anchor 102 is a hexagonal hole, which extends from the tail to the head of the internal hole anchor 102. A cross bar 1021 is arranged at a position of the hexagonal hole close to the head of the internal hole anchor 102. One end of the suture 200 enters from the hexagonal hole, passes through the cross bar 1021 and then passes back. The insertion part 13 is set as a prismatic head, that is, a hexagonal prism that cooperates with the hexagonal hole. Avoidance grooves are arranged on both opposite sides of the hexagonal prism. Both ends of the suture 200 pass through the avoidance grooves and extend out from the tail of the internal hole anchor 102.

[0114] For the formation of the accommodation cavity 223, continue to refer to Figure 12 and Figure 13 , cavities are oppositely arranged on one side of the two jaws 222 close to each other, and the two cavities are butted to form the accommodation cavity 223. A limiting plane 2224 is arranged at one end of the cavity close to the inlet 214, and a limiting inclined plane 2225 is arranged at one end close to the outlet 215. The limiting plane 2224 and the limiting inclined plane 2225 jointly limit the movement of the anchor in the accommodation cavity 223 to ensure that the insertion part 13 can be smoothly inserted into the anchor.

[0115] Furthermore, the cavity is arranged in the middle of the jaw 222, and semi-circular holes are arranged at both ends of the cavity. After the two jaws 222 are butted, the opposite semi-circular holes of the two jaws 222 are butted to form an avoidance hole for the insertion rod 12 to pass through.

[0116] A semi-circular groove 2223 is arranged along the circumferential direction of the jaw 222, and the semi-circular grooves 2223 of the two jaws 222 are butted to form an installation groove. The elastic member is arranged in the installation groove. The elastic member is set as an elastic tape 2211 adapted to the installation groove. The elastic force of the elastic tape 2211 is used to relatively fix the two jaws 222 together to store the anchor. At the same time, after the insertion rod 12 is inserted and fixed with the anchor, a greater thrust is applied to the anchor. The anchor drives the two jaws 222 to overcome the elastic force of the elastic tape 2211, so that one end of the two jaws 222 close to the outlet 215 moves in a direction away from each other, and one end of the anchor clamping assembly 22 close to the outlet 215 is in an open state, and the anchor is ejected from the accommodation cavity 223 and slides out from the outlet 215.

[0117] Continue to refer to Figure 10 and Figure 13 , a slideway 217 is arranged in the storage box 2, and a slide post 2222 slidably connected to the slideway 217 is arranged on the jaw 222. When the insertion rod 12 pushes the anchor, the anchor applies a thrust to the two jaws 222. When the two jaws 222 overcome the elastic force of the elastic tape 2211 and move in a direction away from each other, the movement direction of the two jaws 222 is guided by the cooperation of the slide post 2222 and the slideway 217, so that after the anchor is pushed out of the accommodation cavity 223, the two jaws 222 can return to their original state along the slideway 217 under the action of the elastic restoring force of the elastic tape 2211.

[0118] At both ends of the same side of each jaw 222, slide posts 2222 are provided. The slide way 217 includes a first slide way 2171 and a second slide way 2172. The first slide way 2171 is arranged near the inlet 214, and the second slide way 2172 is arranged near the outlet 215. Both the first slide way 2171 and the second slide way 2172 extend in a direction away from the jaw 222 and towards the outlet 215. The angle between the first slide way 2171 and the symmetry line of the two jaws 222 is smaller than the angle between the second slide way 2172 and the symmetry line of the two jaws 222. When the insertion rod 12 pushes the anchor, the anchor exerts a force on one end of the jaw 222 near the outlet 215, and the two jaws 222 open at one end near the outlet 215, 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 way 2171 and the symmetry line of the two jaws 222 is smaller than the angle between the second slide way 2172 and the symmetry line of the two jaws 222. By providing the two slide ways 217, the movement path of the jaw 222 can be better controlled, and the opening angle of the end of the jaw 222 near the outlet 215 can be ensured.

[0119] Specifically, continue to refer to Figures 9 - 11 , first slide ways 2171 and second slide ways 2172 are provided on both the top shell 211 and the bottom shell 212, and two slide posts 2222 are provided on both sides of the jaw 222. In this way, the two slide posts 2222 on the side of the jaw 222 close to the top shell 211 are respectively in sliding fit with the corresponding first slide way 2171 and second slide way 2172 provided on the top shell 211, and the two slide posts 2222 on the side of the jaw 222 close to the bottom shell 212 are respectively in sliding fit with the corresponding first slide way 2171 and second slide way 2172 provided on the bottom shell 212, so as to ensure the stability and reliability of the movement of the two jaws 222.

[0120] The wire storage and winding structures are symmetrically arranged on both sides of the anchor. After the suture 200 passes through the anchor, the two ends are respectively connected to the two wire storage and winding structures. The insertion rod 12 drives the storage box 2 to move in the direction opposite to the implantation direction, and the wire storage and winding structures can automatically release the suture 200. Before the operation, the two ends of the suture 200 passing through the anchor are respectively stored in the two wire storage and winding structures. After implanting the anchor, only need to pull the handle 11 in the direction opposite to the implantation direction to release all the suture 200, without manually untying the suture 200, further simplifying the operation of the operation and improving the operation efficiency.

[0121] Specifically, as Figures 18 - 20As shown, the wire storage and winding structure includes a ratchet wheel 23, which is rotatably arranged in the storage box 2; the ratchet wheel 23 includes a central shaft 231 and two baffles 232 arranged at both ends of the central shaft 231. The baffles 232 are provided with wire receiving grooves 2321 arranged at intervals. The suture 200 is wound around the central shaft 231, and the tail end of the suture 200 is clamped into two adjacent wire receiving grooves 2321. The suture 200 is wound around the central shaft 231 for storage, and the tail end of the suture 200 is clamped into two adjacent wire receiving grooves 2321 for fixation to prevent loosening. When releasing the suture 200, under the pulling force of the anchor, the tail end of the suture 200 can automatically break free and be released from the wire receiving groove 2321 without manual untying.

[0122] The ratchet wheel 23 can hang various types of sutures 200, such as flat tape wires, flat round wires, absorbable wires, barbed wires, coated wires, sandwich wires, etc. Moreover, the ratchet wheel 23 has enough space to accommodate various specifications and sizes of sutures 200, such as 6-0, 4-0, 2-0, #2, #4, #6, etc.

[0123] Specifically, with continued reference to Figure 10 and Figure 11 , ratchet grooves 216 are provided on both the top shell 211 and the bottom shell 212. The ratchet wheel 23 is arranged in the accommodation space formed by the corresponding ratchet grooves 216 on the top shell 211 and the bottom shell 212. A sleeve 2161 that rotates in cooperation with the central shaft 231 is provided at the center of the ratchet groove 216. Both ends of the central shaft 231 are respectively arranged in the sleeve 2161. When the suture 200 is subjected to the pulling force of the anchor, the central shaft 231 rotates relative to the sleeve 2161, thereby gradually releasing the suture 200.

[0124] Furthermore, as shown in Figure 20 , a plurality of elastic pawls 233 are arranged at intervals along the circumferential direction of the baffle 232. An annular groove is formed between the elastic pawls 233 and the baffle 232. A wire receiving groove 2321 extending radially along the baffle 232 is provided inside each annular groove. A convex column 2331 is provided at the end of the elastic pawl 233. During the rotation of the ratchet wheel 23, when the convex column 2331 contacts the inner wall of the ratchet groove 216, it has a damping effect on the pulling out of the suture 200, ensuring that the suture 200 can be stably pulled out. The plurality of elastic pawls 233 provide a stable moment for the pulling out of the suture 200, ensuring the symmetry of the moment received by the central shaft 231. In addition, during the rotation of the ratchet wheel 23, when the convex column 2331 touches the ratchet groove 216, a clicking sound will be emitted, which serves as a reminder to indicate that the pulling out of the suture 200 by the medical staff is normal.

[0125] With continued reference to Figure 10 and Figure 11, a guiding damping post 218 is further arranged on the circumferential side of the ratchet wheel 23. The suture 200 passing through the anchor is wound around the guiding damping post 218 and then wound around the central shaft 231. The suture 200 winds around the guiding damping post 218, and the guiding damping post 218 can provide damping for the stretching action of the suture 200, reduce the low-frequency vibration generated at the gap between the elastic pawls 233 on the ratchet wheel 23, and ensure the consistency of the pulling force of the suture 200 during the release process of the suture 200.

[0126] Specifically, a notch is arranged in the circumferential direction of the ratchet groove 216. The guiding damping post 218 is arranged outside the notch, and two guiding damping posts 218 are provided. One of them is arranged near the jaw 222 on one side of the notch, and the other is arranged far from the jaw 222 on the opposite side of the notch. The suture 200 passing through the anchor first winds around the guiding damping post 218 near the jaw 222, then winds around the guiding damping post 218 far from the jaw 222 and enters the ratchet groove 216 through the notch, and is wound around the central shaft 231. Such an arrangement enables the suture 200 to always maintain a certain tension during the release process.

[0127] As Figure 21 and Figure 22 shown, in order to ensure the stability of the clamping connection between the handle 11 and the storage box 2, a spherical groove 2121 is arranged on the storage box 2, and a positioning bead 112 is arranged 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 arranged 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 shell, a spring, a ball bead or a cylinder. The ball bead retracts into the shell under pressure. When the ball bead is opposite to the spherical groove 2121, the ball bead extends under the action of the elastic restoring force of the spring and cooperates with the spherical groove 2121 to fix the storage box 2.

[0128] Specifically, the spherical groove 2121 is arranged on the outer surface of the bottom shell 212, and three spherical grooves 2121 are arranged at intervals along the center line of the bottom shell 212. One positioning bead 112 is provided, and the positioning bead 112 only needs to cooperate with one of the spherical grooves 2121 to fix the storage box 2.

[0129] The structural design of the storage box 2 provided in this embodiment converts a simple insertion action into a programmed and precise mechanical fit. During the insertion action, nail picking, wire releasing, and suture 200 tensioning are completed, and mechanical actions such as anchor nail implantation are achieved in cooperation with the handle 11. The anchor nail clamping assembly 22 is provided with two symmetrical sliding jaws 222 that cooperate with the insertion channel 213. The jaws 222 clamp the anchor nail by relying on the elastic tape 2211. After one end of the two jaws 222 close to the inlet 214 is pushed up by the insertion rod 12 to lift the anchor nail, the end close to the outlet 215 is in an open state to release the anchor nail. During the release process, it is restricted by the elastic tape 2211. Through simple structural improvement, the anchor nail clamping assembly 22 can be adapted to any kind of anchor nail. The ratchets 23 and the guiding damping columns 218 on both sides of the anchor nail clamping assembly 22 can semi-automatically manage the suture 200 and release a set length of the suture 200 according to requirements. The guiding damping column 218 is used to ensure that the suture 200 released from the ratchet 23 is released in a tensioned state. The shape of the suture 200 when stored in the box body 21 is an "M" shape with a ring at the tail. This storage box 2 can achieve the individual packaging of the anchor nail, cooperate with the reusable inserter 1 to realize the assembly of the anchor nail and the inserter 1, has a small volume, and allows a sufficient number and types of storage boxes 2 to be prepared before the operation to ensure the response to intraoperative emergencies.

[0130] The inserter 1 provided in this embodiment is a reusable surgical tool, which can appropriately increase the cost to strengthen the strength of the structure and improve the stability of the mechanical structure. This inserter 1 can quickly replace the insertion rod 12 and is fixed to the storage box 2 through the positioning beads 112 on the handle 11. Both the insertion rod 12 and the insertion part 13 are made of hard stainless steel, which ensures the quality of the insertion rod 12 and reduces the frequency of intraoperative instrument failure caused by the quality problems of the inserter 1.

[0131] As Figures 23 - 30 shown, the usage method of the separable modular wire - carrying anchor nail implantation system provided in this embodiment is as follows:

[0132] (1) Hold the handle 11 of the inserter 1 with one hand and hold the storage box 2 with the other hand.

[0133] (2) The insertion rod 12 enters the box body 21 from the entrance 214 of the storage box 2 and moves along the insertion channel 213. When the plug-in portion 13 moves to align with the tail of the anchor, the insertion rod 12 is continued to be pushed, and the plug-in portion 13 is plugged with the anchor. At the same time, the insertion rod 12 and the anchor push the clamping jaws 222, and the clamping jaws 222 move along the slide 217. The two clamping jaws 222 overcome the constraint of the elastic tape 2211, so that the elastic tape 2211 undergoes elastic deformation. The ends of the two clamping jaws 222 close to the exit 215 are in an open state, and the anchor is pushed out of the accommodating cavity 223. During the movement of the anchor, the suture 200 is subjected to tension, and the ratchet 23 is driven to rotate through the guide damping column 218, and the ratchet 23 begins to release the line.

[0134] (3) The insertion rod 12 continues to move, the anchor is pushed forward and slides out of the box body 21 through the outlet 215, and the clamping jaws 222 no longer slide. Under the elastic restoring force of the elastic tape 2211, the two clamping jaws 222 move toward each other until they fit the insertion rod 12 and the suture 200. The anchor drives the suture 200 to continue to move, driving the ratchet 23 to continue to rotate.

[0135] (4) The insertion rod 12 pushes the box body 21 forward, the ratchet 23 continues to rotate to release the line, and the insertion rod 12 continues to move until the box body 21 presses against the handle 11 and cannot move further. The positioning bead 112 at the bayonet 111 of the handle 11 cooperates with the spherical groove 2121 to fix the relative position of the box body 21 and the handle 11.

[0136] (5) By twisting the handle 11 to implant the anchor into the bone, the suture 200 can be released.

[0137] (6) When releasing the suture 200, the head of the suture 200 is fixed at the tail of the anchor, and the handle 11 is pulled in the direction opposite to the implantation direction. The box body 21 moves away from the anchor, and the suture 200 drives the ratchet 23 to rotate. The suture 200 is gradually released. During the release of the suture 200, the guide damping column 218 allows the suture 200 to maintain a certain tension during the pulling process.

[0138] (7) The inserter 1 continues to move in the direction opposite to the implantation direction, and the ratchet 23 continues to rotate to release the suture until the tail end of the suture 200 breaks free from the take-up groove 2321 and slides out of the box body 21, and the suture 200 is released.

[0139] (8) After the suture thread 200 is released, the box body 21 can be removed from the insertion rod 12.

[0140] After the implantation of one anchor is completed, when the next anchor is implanted, the above-mentioned inserter 1 is assembled with the next storage box 2, and the implantation of the next anchor is continued according to the above-mentioned steps, and this cycle is repeated until the implantation is completed.

[0141] Embodiment 2:

[0142] This embodiment provides a separable modular wire - threaded anchor implant system, which has the same working principle and the structure of most components as the separable modular wire - threaded anchor implant system provided in Embodiment 1, and the same parts will not be described in detail here. The main differences are: the structure of the insertion channel 213, the structure of the anchor - holding assembly 22, the wire storage and winding structure, and the fixing structure between the handle 11 and the storage box 2.

[0143] As Figures 31 - 36 shown, the insertion channel 213 is set as a through - type, with one end communicating with the inlet 214 and the other end communicating with the outlet 215. That is, the insertion channel 213 extends from the inlet 214 to the outlet 215. The anchor - holding assembly 22 is arranged on the rib, and the height of the rib between the anchor - holding assembly 22 and the inlet 214 is higher than the height of the rib under the anchor - holding assembly 22, so as to ensure that the center line of the anchor - holding assembly 22 and the center line of the insertion channel 213 are on the same straight line, and the stability of the insertion rod 12 when it is inserted into the box body 21 and ejects the anchor is higher, and there is a constraint on the rotation direction during the whole process of pushing the insertion rod 12.

[0144] Specifically, the height of the rib between the anchor - holding assembly 22 and the inlet 214 on the bottom shell 212 is higher than the height of the rib under the anchor - holding assembly 22. The rib on the top shell 211 extends from the inlet 214 to the anchor - holding assembly 22.

[0145] Furthermore, the connection between the inlet 214 and the insertion channel 213 is set in a funnel shape to facilitate the insertion rod 12 to enter more smoothly.

[0146] Specifically, for the two jaws 222 of the anchor - holding assembly 22, a sliding column 2222 is arranged on the same side of each jaw 222, and the slideway 217 extends in a direction away from the jaw 222 and towards the outlet 215. A sliding column 2222 is arranged on the same side of each jaw 222. When the jaw 222 moves, two sliding columns 2222 are arranged on both sides of the jaw 222, which respectively cooperate with the slideways 217 on the top shell 211 and the bottom shell 212 for sliding.

[0147] Further, the elastic member is disposed around the sliding columns 2222 oppositely arranged on the two clamping jaws 222. The sliding columns 2222 include a column body and a sliding head, the outer diameter of the sliding head is larger than that of the column body, the sliding head is slidably disposed in the sliding groove 217, the elastic member is an elastic rubber ring 2212, and the elastic rubber ring 2212 is clamped between the sliding head and the side wall of the clamping jaw 222. With such a setting, the clamping jaw 222 can open at a larger angle when releasing the anchor, so as to accommodate larger-sized anchors. One elastic rubber ring 2212 can be provided, that is, one side of the two clamping jaws 222 is restricted by the elastic rubber ring 2212; two elastic rubber rings 2212 can also be provided, that is, both sides of the two clamping jaws 222 are restricted by the elastic rubber rings 2212.

[0148] The wire storage and winding structure includes a winding groove 2191 and a wire receiving hole 2192. The winding grooves 2191 are symmetrically disposed on the outer periphery of the storage box 2. One of the winding grooves 2191 is provided with a wire passing hole 2193. The wire receiving holes 2192 are symmetrically disposed on the outer periphery of the storage box 2 and communicate with the inside of the storage box 2; the suture 200 passing through the anchor passes through the wire passing hole 2193 and is wound in the oppositely arranged winding grooves 2191, and the tail end of the suture 200 is clamped into the oppositely arranged wire receiving holes 2192; the symmetry lines of the winding grooves 2191 and the wire receiving holes 2192 are both perpendicular to the center line of the insertion channel 213. With such a setting, the suture 200 passing through the anchor passes out of the box body 21 from the wire passing hole 2193, winds around the winding groove 2191 on the surface of the box body 21, winds around the winding groove 2191 for several turns and then winds and is fixed in the wire receiving hole 2192. The suture 200 on the winding groove 2191 needs to be manually untied to be released, and cannot be automatically released by driving the suture 200 when the anchor is ejected by the insertion rod 12.

[0149] Further, the wire storage and winding structure further includes a wire storage groove 2194. The wire storage groove 2194 is disposed in the storage box 2, and the suture 200 can be limited in the wire storage groove 2194. The suture 200 passing through the anchor passes through the wire storage groove 2194 and then passes through the wire passing hole 2193. The suture 200 enters the internal wire storage groove 2194 after passing through the anchor, is stacked for several turns, and then is led out from the wire storage groove 2194 and passes through the wire passing hole 2193. This part stores the suture 200 inside the box body 21. The wire storage groove 2194 squeezes and fixes the suture 200 stored inside the box body 21. When the anchor is ejected, the suture 200 in the wire storage groove 2194 has a certain resistance under the squeezing force.

[0150] Specifically, the storage wire groove 2194 is formed by enclosing three rectangular bumps arranged at intervals between two opposite vertical plates on the bottom case 212 or the top case 211. There are gaps on both sides of the three rectangular bumps between the two vertical plates to form a U-shaped groove. Limit plates are provided at the upper ends of the rectangular bumps. The limit plate on the middle rectangular bump is connected to the first vertical plate and is arranged at an interval from the second vertical plate. The limit plates on the rectangular bumps on both sides are connected to the second vertical plate and are arranged at an interval from the first vertical plate. The interval between the limit plate and the rectangular bump and the vertical plate is smaller to press the suture 200 and prevent the suture 200 from coming out. After the suture 200 is stacked in the U-shaped groove for several turns, it is pressed by the limit plate and led out from the U-shaped groove.

[0151] Of course, in other embodiments, the storage wire groove 2194 can also be set as a serpentine limit groove, and the suture 200 is stored by surrounding the serpentine limit groove.

[0152] Further, the length of the suture 200 stored inside the box body 21 is equal to the length of the insertion rod 12. When the insertion rod 12 ejects the anchor to the limit position, the suture 200 in the storage wire groove 2194 is completely released.

[0153] Further, the wire storage and winding structure further includes a tensioning member 2195. The tensioning member 2195 is arranged between the anchor and the storage wire groove 2194. The suture 200 passing through the anchor is tensioned by the tensioning member 2195 and then enters the storage wire groove 2194. The tensioning member 2195 includes a guiding vertical plate and a guiding column. The guiding vertical plate is arranged outside the first vertical plate and is arranged at an angle with the first vertical plate. One end of the guiding vertical plate is connected to the first vertical plate, and the other end is connected with a guiding column. The suture 200 passing through the anchor bypasses the guiding column and enters the storage wire groove 2194 under the guidance of the guiding vertical plate. The limit plate presses the suture 200. When the suture 200 is released, the guiding column and the guiding vertical plate can ensure that the suture 200 in the storage wire groove 2194 maintains a certain tension when released.

[0154] For the inserter 1 provided in this embodiment, a clamping member 113 is arranged on one side of the bayonet 111 of the handle 11. The clamping member 113 is rotatably connected to the handle 11 and is used to cooperate with the other side wall of the bayonet 111 to clamp the storage box 2. When pressing one end of the clamping member 113, the other end of the clamping member 113 can move in a direction away from the other side wall of the bayonet 111. The clamping member is a toggle clamping claw. The toggle clamping claw is rotatably connected to the handle 11 through a rotating shaft. A pressing part 1132 is arranged at one end of the toggle clamping claw. By pressing the pressing part 1132, the other end of the toggle clamping claw moves in a direction away from the other side wall of the bayonet 111, and the storage box 2 can be loosened and the storage box 2 can be removed.

[0155] Specifically, a plurality of card slots 2122 are provided on the storage box 2, and a plurality of card protrusions 1131 are provided at the other end of the card connector 113. The card protrusions 1131 are engaged with the card slots 2122. The card protrusions 1131 are provided as trapezoidal teeth, which greatly increases the connection strength between the storage box 2 and the handle 11, prevents the storage box 2 from accidentally falling off, and after use, pressing the pressing part 1132 can detach the storage box 2.

[0156] Embodiment Three:

[0157] This embodiment provides a separable modular suture - anchored implant system, which has the same working principle and the structure of most components as the separable modular suture - anchored implant system provided in Embodiment One, and the same parts will not be described in detail here. The main differences are: the structure of the insertion part 13 and the structure of the anchor - holding assembly 22.

[0158] As Figures 37 - 44 shown, in the separable modular suture - anchored implant system provided in this embodiment, the full - suture anchor 103 is a flexible anchor, the middle part is flat, and the full - suture anchor 103 is placed horizontally during storage. The insertion part 13 includes an insertion rod 131 and a fork - shaped head 1311. The fork - shaped head 1311 is provided at the end of the insertion rod 131 away from the insertion rod 12. After the fork - shaped head 1311 clamps the flat structure in the middle of the full - suture anchor 103, a force is applied to the full - suture anchor 103 through the insertion rod 12, and the full - suture anchor 103 deforms and presents a V - shape when pushed out of the storage box 2. The structures of the insertion part 13 and the anchor - holding assembly 22 are improved according to the structure of the full - suture anchor 103.

[0159] In the anchor - holding assembly 22 provided in this embodiment, the center line of the accommodation cavity 223 is perpendicular to the symmetry line of the two clamping jaws 222. A through - hole 224 with a center line coinciding with the symmetry line of the two clamping jaws 222 is formed by connecting 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 changed according to the structure of the full - suture anchor 103, so that the storage box 2 is also suitable for storing the full - suture anchor 103.

[0160] Furthermore, in order to facilitate the horizontal full - suture anchor 103 to be more easily ejected from the anchor - holding assembly 22 by the insertion rod 12, one end of the clamping jaw 222 close to the outlet 215 of the storage box 2 is provided as an opening 2221, and the accommodation cavity 223 is communicated with the opening 2221.

[0161] As Figures 39 - 43As shown, the full suture anchor 103 is horizontally placed in the accommodation cavity 223. The suture 200 extends from both ends of the full suture anchor 103 and is respectively connected to the suture storage and winding structures on both sides. The insertion rod 12 enters the box body 21 from the through hole 224, moves to clamp the flat structure in the middle of the full suture anchor 103 with the fork head 1311, and continues to move. The middle part of the full suture anchor 103 deforms into a protruding shape, and the jaws 222 gradually open under the extrusion of the protruding shape. The insertion rod 12 continues to move, and the full suture anchor 103 continues to move and is extruded into an approximately V shape. After the jaws 222 open at an angle sufficient for the full suture anchor 103 to pass through, the angle between them no longer expands further under the action of the elastic tape 2211. The ratchet 23 starts to rotate under the traction of the suture 200. The insertion rod 12 continues to move, and the full suture anchor 103 can completely break away from the opening 2221 and eject the box body 21.

[0162] When implanting the full suture anchor 103, it is necessary to strike the tail of the handle 11 to knock the full suture anchor 103 into the predetermined position and depth. Then, one can hold the handle 11 and pull out the insertion rod 12 in the direction opposite to the implantation direction. The ratchet 23 rotates to release the suture 200. After the suture 200 is completely released, the implantation is completed, and the box body 21 can be disassembled from the insertion rod 12.

[0163] As Figure 44 shown, a stress release platform 1312 and a marking line 1313 are also provided on the insertion rod 131. The marking line 1313 is arranged between the stress release platform 1312 and the insertion rod 12. The function of the stress release platform 1312 is to reduce the extrusion contact stress during the knocking implantation. The marking line 1313 indicates the implantation depth during the operation. The diameter of the insertion rod 131 is smaller than that of the insertion rod 12, reducing the interference fit at the bone-insertion rod 131-anchor interface generated by the knocking implantation.

[0164] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
