Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a full suture anchor assembly device, a full suture anchor implantation device and an assembly method. Background Art

[0002] In the field of medical devices, traditional bone anchors are made of hard materials, and their contact with bones is hard contact. The friction and impact between hard objects will cause secondary damage to the bones and even lead to surgical failure. At present, some anchor implantation devices use full suture anchors composed of medical textile yarns, which can fix the sutures by pulling the full suture anchors with a traction line. Full suture anchors use the flexibility of textile yarns and the overall deformability to reduce the amount of bone loss in pre-drilled holes and avoid secondary damage to the bones.

[0003] However, since the full suture anchor is woven from textile yarns, the assembly process between it and the implanter is more difficult. The full suture anchor and the implanter usually need to be pre-assembled and disassembled during surgery. The full suture anchor cannot be replaced. When multiple full suture anchors are needed during surgery, each full suture anchor needs to be equipped with a disposable implanter, which increases the cost of surgery. Moreover, the structure of the full suture anchor is not as dense as that of a hard anchor. During the assembly process of the implanter and the full suture anchor, the implant rod often pierces the nail body. On the one hand, it will destroy the structure of the full suture anchor and make it lose its fixing performance. On the other hand, it will cause the full suture anchor to fall off, making it impossible for the implanter to complete the delivery, resulting in implantation failure. Summary of the invention

[0046] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] Embodiment 1

[0053] like Figures 1 to 4 As shown, the first embodiment provides a full suture anchor assembly device for assembling the nail body 1 of the full suture anchor into the fixing groove 21 of the implant rod 2. The full suture anchor also includes two traction lines 4 connected to the two ends of the nail body 1.

[0054] The full suture anchor assembly device includes a clamping member 100 and a guide member 200 connected to the clamping member 100. The clamping member 100 is provided with a clamping groove 101, and the clamping groove 101 is used to accommodate the nail body 1. The guide member 200 is arranged at the opening of the clamping groove 101, and the guide member 200 includes two clamping pieces 201 arranged opposite to each other. The guide member 200 can be inserted into the fixing groove 21 of the implant rod 2, and the two clamping pieces 201 are in a guiding state of being away from each other to form a guide channel, and the two ends of the guide channel are respectively connected to the clamping groove 101 and the fixing groove 21. When the guide 200 is in the guiding state, the nail body 1 can be clamped in the fixing groove 21 through the guide channel. During this process, the clamping sheet 201 of the sheet structure provides guiding protection for the nail body 1. The nail body 1 is finally clamped in the fixing groove 21 through the guide channel, and will not contact the sharp end of the implant rod 2, thereby avoiding the risk of being pierced by the implant rod 2 and ensuring that the fixing performance of the nail body 1 is not affected; moreover, the nail body 1 is clamped in the fixing groove 21, so that the implant rod 2 can effectively carry the nail body 1, preventing the nail body 1 from falling off and ensuring smooth implantation. The full suture anchor assembly device has a simple structure and is reusable. For surgical applications requiring multiple nail bodies 1, the nail body 1 can be assembled multiple times for the same implant rod 2, and the full suture anchor implantation device to which the implant rod 2 belongs can be reused. It does not need to be pre-assembled with the nail body 1, nor does it need to be replaced multiple times, thereby saving surgical costs.

[0055] The movement of the nail body 1 can be operated by pulling the traction line 4 or by manual pulling. The movement of the two clamping pieces 201 away from each other can be achieved by a driving member as a power source, and in this embodiment, it can also be achieved by squeezing the nail body 1.

[0056] Specifically, the two ends of the clamping groove 101 along the first direction are connected to form two ports respectively, and the nail body 1 is arranged in the two ports; wherein, the first direction is perpendicular to the length direction of the guide channel, so that the nail body 1 and the guide channel are perpendicular to each other, which facilitates the nail body 1 to quickly enter the guide channel. The first direction is also the extension direction of the clamping groove 101, and the extension direction of the guide groove 102 and the extension direction of the clamping groove 101 are arranged at an angle, and the two ends of the nail body 1 are arranged to bear the external force and make the nail body 1 squeeze the two clamping pieces 201 away from each other to form a guide channel. The external force pulls the two ends of the nail body 1 to move toward the clamping groove 101, and squeezes the two clamping pieces 201 to move away from each other during the movement to form a guide channel, and finally is clamped in the clamping groove 101 through the guide channel. In this way, there is no need to provide a driving member for the clamping piece 201, simplifying the structure. In this embodiment, the extension direction of the guide groove 102 and the extension direction of the clamping groove 101 are perpendicular to each other.

[0057] In order to make it easier to apply force to the nail body 1, in the present embodiment, two traction lines 4 are respectively provided at both ends of the nail body 1. By pulling the traction lines 4, force can be applied from both ends of the nail body 1 at the same time to move it. The operation is more convenient, and the traction lines 4 are evenly stressed, thereby ensuring that the position of the traction lines 4 in the clamping groove 101 is more accurate.

[0058] The guide member 200 has an initial state, in which the two clamping pieces 201 at least partially fit each other to close the guide channel, thereby preventing the guide channel from failing and causing the traction line 4 to fall off from the clamping member 100. In order to ensure the closability of the guide channel, one end of the clamping piece 201 is fixed to the clamping member 100 to form a fixed end, and the free end of the clamping piece 201 forms the guide channel.

[0059] There is an arc-shaped transition structure between the fixed end and the free end of the clamping piece 201. The free ends of the two clamping pieces 201 fit together, so that the two clamping pieces 201 are in a duckbill shape. On the one hand, the arc-shaped transition structure is conducive to guiding the nail body 1, reducing the resistance during the movement of the nail body 1, and avoiding wear and deformation during assembly. On the other hand, the duckbill structure makes the guide 200 have a certain elasticity, so that it can better restore the initial state from the guiding state.

[0060] In order to further improve the structural strength of the guide member 200, the guide member 200 further includes a fixing portion 202, and both ends of the fixing portion 202 are respectively connected to the two clamping pieces 201. Figure 4 As shown. The fixing portion 202 is at least partially embedded in the clamping member 100. In this embodiment, in order to ensure the symmetry of the two clamping pieces 201 and prevent the two clamping pieces 201 from being skewed in the fixing groove 21, the fixing portion 202 is a partial ring, and the notches thereof are respectively connected to the two clamping pieces 201; the fixing portion 202 and the clamping groove 101 are coaxially arranged, and the radial dimension of the fixing portion 202 is larger than the radial dimension of the clamping groove 101, so that the two clamping pieces 201 at the notch of the fixing portion 202 are just arranged on both sides of the opening of the clamping groove 101.

[0061] Optionally, the two clamping pieces 201 and the fixing part 202 are integrally formed by sheet metal processing, have good structural strength, are made of stainless steel sheets, have good anti-deformation performance, are not easy to rust, and meet the operating requirements of a sterile environment.

[0062] The guide member 200 and the clamping member 100 are integrally connected. The clamping member 100 is processed by injection molding, and the guide member 200 is used as an embedded part during processing to achieve the connection between the two.

[0063] In order to improve the position accuracy of the implant rod 2 and the clamping piece 201, the clamping piece 100 is further provided with a guide groove 102, one end of the guide groove 102 is connected to the clamping groove 101, and the free end of the clamping piece 201 extends toward the guide groove 102, so that the implant rod 2 can be inserted into the clamping groove 101. In this embodiment, the specific shape of the clamping piece 100 is not limited. For example, the clamping piece 100 is formed by two block structures connected to each other, one of which is used to form the clamping groove 101 and the guide groove 102, and the other is used to form a hand-held structure, which simplifies the structure, facilitates miniaturization and lightweight, is convenient for hand-held operation, and is easy to use.

[0064] The cross-sectional dimension of the clamping groove 101 along the direction perpendicular to the length is greater than the cross-sectional dimension of the guide groove 102 along the direction perpendicular to the length. Because the nail body 1 is in a free state when in the clamping groove 101, the guide groove 102 with a smaller cross-sectional dimension can better adapt to the size of the implant rod 2 and squeeze the nail body 1, so that the nail body 1 is in a state to be implanted. Furthermore, the cross-sectional dimension of the guide groove 102 is compatible with the shape of the implant rod 2, and the guide groove 102 has a better constraint on the implant rod 2, preventing the implant rod 2 from moving in position when the nail body 1 passes through the guide channel, thereby affecting the assembly effect.

[0065] Embodiment 2

[0066] The second embodiment provides a full suture anchor implantation device, which uses the full suture anchor assembly device in the first embodiment to assemble the nail body 1 of the full suture anchor into the fixing groove 21 of the implantation rod 2, wherein the full suture anchor includes a nail body 1 and two traction lines 4 connected at both ends of the nail body 1. Figures 5 to 8 As shown, the full suture anchor implantation device includes an implant rod 2 and an operating assembly 3. The implant rod 2 can be detachably connected to the operating assembly 3 by moving along its own axis, and a fixing groove 21 is provided at one end of the implant rod 2 away from the operating assembly 3. The other ends of the two traction lines 4 away from the nail body 1 are both wound and connected to the operating assembly 3.

[0067] When the full suture anchor assembly device in the first embodiment is used to assemble the nail body 1, the nail body 1 with the traction wire 4 at both ends is firstly inserted into the clamping groove 101 of the clamping member 100, and the end of the traction wire 4 away from the nail body 1 is connected to the operating component 3 to form a relaxed state, and the clamping member 100 is driven to move away from the operating component 3 by the movement of the implant rod 2 along its own axis. In this process, the traction wire 4 in the relaxed state is tensioned until the tension force formed pulls the nail body 1 to squeeze the two clamping sheets 201 away from each other to form a guide channel, and is clamped in the fixing groove 21 of the implant rod 2 through the guide channel. During the assembly process, the clamping sheet 201 of the sheet structure provides guidance and protection for the nail body 1, avoiding the risk of the nail body 1 being pierced by the implant rod 2, and ensuring that the fixing performance of the nail body 1 is not affected; moreover, the nail body 1 can be reliably clamped in the fixing groove 21, and the full suture anchor implantation device can effectively carry the nail body 1 to ensure smooth implantation. The implant rod 2 and the operating assembly 3 are reusable, and can be quickly assembled to implant multiple nail bodies 1 with a full set of suture anchor implantation devices during surgery, thereby saving surgical costs.

[0068] The operating assembly 3 includes a plug-in seat mechanism 31 and a handle mechanism 32. The plug-in seat mechanism 31 is detachably connected to the end of the implant rod 2 away from the fixing groove 21. The plug-in seat mechanism 31 includes a sliding rod 311, one end of the sliding rod 311 is connected to the implant rod 2, and the other end of the sliding rod 311 away from the implant rod 2 can be movably constrained to the handle mechanism 32 along its own axis. The axial movement of the implant rod 2 is achieved by the movement of the sliding rod 311 along its own axis. The handle mechanism 32 is convenient for handheld operation.

[0069] The handle mechanism 32 is provided with an insertion hole 321, and the sliding rod 311 is movably inserted into the insertion hole 321. The operating assembly 3 also includes a locking member 33 movably connected to the handle mechanism 32, and the locking member 33 has an unlocked state and a locked state. The locking member 33 in the locked state is at least partially located on the moving path of the sliding rod 311 to abut and limit the movement of the sliding rod 311, and the locking member 33 in the unlocked state is located outside the moving path. In the second embodiment, the locking member 33 is hinged to the handle mechanism 32 through a hinge shaft, and the two sides of the hinge shaft respectively form a locking end and an unlocking end.

[0070] The handle mechanism 32 is provided with a locking hole 325 connected to the insertion hole 321, and the sliding rod 311 is provided with a plurality of ratchet teeth 3113 arranged at intervals along the axial direction. The locking piece 33 in the locked state is rotated until the locking end passes through the locking hole 325 and engages with one of the ratchet teeth 3113 on the sliding rod 311, and the sliding rod 311 can no longer move axially, thereby preventing the sliding rod 311 from sliding arbitrarily during the operation; when the implant rod 2 needs to be moved, the unlocking end is pressed to rotate the locking piece 33, and the locking end and the ratchet teeth 3113 of the sliding rod 311 are separated. At this time, the sliding rod 311 can move axially, thereby realizing the axial movement of the implant rod 2.

[0071] In order to maintain the reliability of the locking member 33 in the locked state, the operating assembly 3 also includes an elastic member 34, which applies an elastic force to the unlocking end so that the locking member 33 always has a tendency to rotate in the direction of the locking end toward the locking hole 325. Exemplarily, the elastic member 34 is a compression spring, and the two ends of the compression spring are respectively connected to the handle mechanism 32 and the unlocking end, and the elastic force of the compression spring always pushes the unlocking end upward. Under the elastic force of the compression spring, the locking end is firmly pressed on the ratchet 3113 of the sliding rod 311. Moreover, after pressing the unlocking end to perform the unlocking operation, the unlocking end is released, and the locking member 33 can quickly return to the locked state under the elastic force of the compression spring, thereby avoiding axial movement of the implant rod 2 and misoperation.

[0072] The handle mechanism 32 includes a winding member 322 and a handle member 323, and the handle member 323 and the winding member 322 are detachably connected via a buckle structure 324. Both ends of the winding member 322 are provided with winding grooves, which are respectively used to wind two traction lines 4 to prevent the traction lines 4 from falling off and ensure that the traction lines 4 can apply reliable traction to the nail body 1. The handle member 323 is provided with an insertion hole 321, and the sliding rod 311 is movably inserted into the insertion hole 321. The detachable connection between the handle member 323 and the winding member 322 is convenient for assembly. The insertion seat mechanism 31 can be first connected to the handle member 323 through the sliding rod 311, and the traction line 4 with the nail body 1 is wound on the winding member 322, and then the winding member 322 and the handle member 323 are clamped together through the buckle structure 324, which is convenient for assembly.

[0073] In actual application, in order to further improve the convenience of users replacing the nail body 1 of the full suture anchor implantation device, the full suture anchor, the full suture anchor assembly device in Example 1 and the winding member 322 can be preassembled. Specifically, the nail body 1 of the full suture anchor is inserted into the clamping groove 101 of the clamping member 100, and the two traction wires 4 at both ends of the nail body 1 are respectively wound and connected to the winding member 322. The above is used as a set of preassembled parts, which are sterilized and packaged in advance to facilitate the operator to replace the nail body 1 for the full suture anchor implantation device. When it is necessary to assemble the nail body 1 to the full suture anchor implantation device, the above preassembled parts are used to dock the implantation rod 2 of the full suture anchor implantation device with the clamping member 100 of the preassembled parts, so that the guide member 200 is inserted into the fixed groove 21 of the implantation rod 2, and at the same time, the winding member 322 with the traction wire 4 wound and the handle member 323 are clamped. Then, the implant rod 2 is pushed to move along its own axis to drive the clamping member 100 to move away from the operating assembly 3 until the nail body 1 squeezes the two clamping pieces 201 and is clamped in the fixing groove 21 of the implant rod 2 through the guide channel.

[0074] It should be noted that, in the above process, since the axial movement of the implant rod 2 is driven by the insert seat mechanism 31, in actual application, the insert seat mechanism 31 is pushed to drive the implant rod 2 to move axially.

[0075] Specifically, the buckle structure 324 includes a buckle hole 3241 provided on the handle member 323, and a buckle 3242 provided on the winding member 322. The two ends of the buckle hole 3241 are connected, and the buckle 3242 is buckled in the buckle hole 3241, and the end thereof protrudes from the surface of the handle member 323; the end thereof has a protruding portion, and the cross-sectional dimension of the protruding portion is larger than the cross-sectional dimension of the buckle hole 3241, so as to prevent the buckle 3242 from being loosened from the buckle hole 3241. In order to facilitate the passing of the larger protruding portion through the buckle hole 3241, at least part of the buckle 3242 is provided with a notch, so that the buckle 3242 forms two oppositely arranged half buckles. When the buckle is mounted, the two opposite half buckles are squeezed to be close to each other, and the protruding portion can pass through the buckle hole 3241 relatively easily; then, the two half buckles are reset so that the protruding portion is stuck on one side of the buckle hole 3241. Similarly, when the buckle structure 324 needs to be disassembled, the two opposing half buckles are squeezed to bring them closer to each other, and the protrusion can pass through the buckle hole 3241 more easily to separate the handle member 323 and the winding member 322.

[0076] The insertion seat mechanism 31 also includes a connecting sleeve 312, one end of the sliding rod 311 can be rotatably constrained to the connecting sleeve 312 around its own axis, and the other end of the sliding rod 311 extending to the outside of the connecting sleeve 312 can be movably constrained to the handle mechanism 32 along its own axis, that is, the sliding rod 311 can rotate relative to the connecting sleeve 312, and the sliding rod 311 can also drive the connecting sleeve 312 to move axially relative to the handle mechanism 32.

[0077] In order to realize the rotatable constrained connection of the sliding rod 311, the sliding rod 311 has a radially protruding limiting boss, and the connecting sleeve 312 includes two mutually connected first sleeves 3124 and second sleeves 3125, the first sleeve 3124 and the second sleeve 3125 are surrounded to form an installation cavity, the sliding rod 311 passes through the second sleeve 3125, so that the limiting boss is located in the installation cavity, and then the first sleeve 3124 and the second sleeve 3125 are surrounded and connected, under the limiting effect of the limiting boss, the sliding rod 311 will not be separated from the connecting sleeve 312, and can rotate around its own axis. The first sleeve 3124 and the second sleeve 3125 can be fixed by welding, or formed into a detachable structure by threaded connection.

[0078] In order to realize the detachable connection between the insertion seat mechanism 31 and the implant rod 2, a mounting opening 3121 is provided at one end of the connecting sleeve 312 away from the handle mechanism 32, and a mounting groove 3111 is provided at the end of the sliding rod 311 away from the handle mechanism 32, and the mounting groove 3111 is connected to the mounting opening 3121. The implant rod 2 includes a rod body 22 and a plug-in portion 23, the cross-sectional size of the plug-in portion 23 is larger than the cross-sectional size of the rod body 22, and the plug-in portion 23 can be inserted into the plug-in groove 3111 through the mounting opening 3121. A shielding portion 3122 is provided at the mounting opening 3121, and the sliding rod 311 and the connecting sleeve 312 can rotate relative to each other so that the shielding portion 3122 at least shields a part of the plug-in portion 23 to limit the plug-in portion 23 from being separated from the plug-in groove 3111. In this embodiment, the shielding portion 3122 is two bosses arranged opposite to each other, and the bosses extend radially toward the axial direction of the connecting sleeve 312, and the plug-in portion 23 can pass through the installation opening 3121 and be inserted into the insertion groove 3111, and then, through the relative rotation of the sliding rod 311 and the connecting sleeve 312, the plug-in portion 23 is rotated to be at least partially blocked by the shielding portion 3122. Under the blocking restriction of the shielding portion 3122, the plug-in portion 23 will not be separated from the insertion groove 3111, and the connection between the insertion seat mechanism 31 and the implant rod 2 is realized. Accordingly, when the implant rod 2 needs to be disassembled, the plug-in portion 23 is rotated to an angle that is not blocked by the shielding portion 3122 through the relative rotation of the sliding rod 311 and the connecting sleeve 312, and the implant rod 2 can be removed.

[0079] The relative rotation of the sliding rod 311 and the connecting sleeve 312 can be achieved by holding the sliding rod 311 to rotate the connecting sleeve 312; holding the connecting sleeve 312 to rotate the sliding rod 311; or by simultaneously rotating the connecting sleeve 312 and the sliding rod 311 relative to each other. The operation is relatively convenient and the operator can choose according to usage habits and operating space.

[0080] In order to limit the relative position of the shielding portion 3122 and the plug-in portion 23 and ensure convenient assembly and disassembly, one of the connecting sleeve 312 and the sliding rod 311 is provided with a limiting slot 3112, and the other is provided with a limiting protrusion, which is slidably embedded in the limiting slot 3112. The two side walls of the limiting slot 3112 are respectively used to abut against the limiting protrusion to limit the rotation angle between the sliding rod 311 and the connecting sleeve 312. When the limiting protrusion abuts against one of the two side walls, the plug-in portion 23 can be inserted into the insertion slot 3111 through the installation opening 3121. When the limiting protrusion abuts against the other of the two side walls, the shielding portion 3122 at least blocks part of the plug-in portion 23. The cooperation between the limiting protrusion and the limiting groove 3112 can increase the operating feel, so that the relative rotation of the sliding rod 311 and the connecting sleeve 312 has two extreme positions. In one of the extreme positions, the plug-in part 23 can pass through the installation opening 3121 and be inserted into the insertion groove 3111 or detached from the insertion groove 3111. In the other extreme position, the plug-in part 23 is blocked by the blocking part 3122 and is stably clamped in the insertion groove 3111.

[0081] When the relative positions of the sliding rod 311 and the connecting sleeve 312 are rotated to the right position, the locking member 33 engages and locks the ratchet teeth 3113, which can prevent the sliding rod 311 from axial movement and rotation, and the movement of the sliding rod 311 is completely restricted.

[0082] Embodiment 3

[0083] The third embodiment provides a full suture anchor implantation device, and the full suture anchor assembly device in the first embodiment is used to assemble the nail body 1 into the fixing groove 21 of the implantation rod 2. The full suture anchor implantation device provided in the third embodiment is basically the same as the full suture anchor implantation device in the second embodiment, and only some of the settings are different, and the same contents in the second embodiment will not be repeated in this embodiment.

[0084] In this embodiment, if Fig. 9 and Fig.10 As shown, the handle mechanism 32 is provided with an adjustment hole 326 with two ends through it, and the sliding rod 311 is movably inserted into the adjustment hole 326. The adjustment hole 326 is configured to limit the rotation of the sliding rod 311 around its own axis, that is, the sliding rod 311 can move axially but cannot rotate in the adjustment hole 326. The other end of the sliding rod 311 away from the implant rod 2 is provided with an adjustment thread 3114.

[0085] The operating assembly 3 also includes an adjusting hand wheel 35 and a knocking member 36. The adjusting hand wheel 35 is rotatably connected to the handle mechanism 32. The handle mechanism 32 is provided with a rotation groove. The adjusting hand wheel 35 is rotatably constrained in the rotation groove. The adjusting hand wheel 35 is provided with a through adjusting threaded hole 351. The adjusting hand wheel 35 is threadedly connected to the sliding rod 311 through the adjusting threaded hole 351 to drive the sliding rod 311 to move axially. When the adjusting hand wheel 35 is rotated, the sliding rod 311 constrained in the adjusting hole 326 moves axially, thereby driving the implant rod 2 to move axially. The axial movement of the sliding rod 311 is achieved through the threaded connection structure, and there is no need to set an axial locking structure. The self-locking of the adjusting threaded hole 351 and the adjusting thread 3114 can achieve the axial locking of the sliding rod 311. Moreover, compared with the manual method, adjusting the axial position of the sliding rod 311 by rotating the adjusting hand wheel 35 has the advantages of high adjustment accuracy and accurate positioning.

[0086] Specifically, at least part of the adjustment hole 326 is a rectangular cross-section hole, and at least part of the rod body of the sliding rod 311 located in the adjustment hole 326 is a rectangular cross-section rod. The rectangular cross-section rod is inserted into the rectangular cross-section hole and can move axially but cannot rotate.

[0087] The sliding rod 311 extends through the adjusting threaded hole 351 to penetrate the adjusting hand wheel 35 to connect the knocking piece 36. The sliding rod 311 and the knocking piece 36 can be connected by interference fit, threaded connection and other structures. When the nail body 1 is knocked and implanted, the knocking piece 36 is used to withstand the knocking action, and then transmit the knocking force to the nail body 1 through the sliding rod 311 and the implantation rod 2. Compared with the operation of directly knocking the adjusting hand wheel 35 during implantation, the operation of knocking on the knocking piece 36 reduces the damage of the knocking force to the threaded connection structure between the adjusting hand wheel 35 and the sliding rod 311, reduces the damage rate of the operating component 3, and ensures the repeatable efficiency of the use of the operating component 3.

[0088] It should be noted that, in this embodiment, since the sliding rod 311 cannot rotate around its own axis, when the implant rod 2 is installed, the relative rotation between the sliding rod 311 and the connecting sleeve 312 is only achieved by rotating the connecting sleeve 312 .

[0089] Embodiment 4

[0090] Embodiment 4 of the present invention provides an assembly method, using the full suture anchor assembly device in embodiment 1 to assemble the full suture anchor implantation device in embodiment 2 or embodiment 3, and assembling the nail body 1 into the fixing groove 21 of the implantation rod 2.

[0091] The assembly method comprises the following steps:

[0092] S1. Insert the nail body 1 with the traction wires 4 at both ends into the clamping groove 101 of the clamping member 100. The other end of the traction wire 4 away from the nail body 1 is connected to the operating component 3, and the traction wire 4 is in a relaxed state.

[0093] S2, docking the implant rod 2 and the clamping member 100, so that the guide member 200 is inserted into the fixing groove 21 of the implant rod 2.

[0094] S3, the implant rod 2 is moved along its own axis in a direction away from the operating assembly 3, and the implant rod 2 drives the clamping member 100 to move until the traction wire 4 is transformed from a relaxed state to a tensioned state.

[0095] S4, the implant rod 2 is continuously moved until the tensioned traction wire 4 pulls the nail body 1 to squeeze the two clamping pieces 201 away from each other so as to be clamped in the clamping groove 101 through the guide channel.

[0096] The assembly method utilizes the movement of the implant rod 2 along its own axis to drive the clamping piece 100 to move in a direction away from the operating component 3 so that the traction line 4 in a relaxed state is tensioned, thereby utilizing the tensioning force formed by the traction line 4 to pull the nail body 1 to squeeze the two clamping pieces 201 away from each other to form a guide channel. The guide channel formed by the clamping pieces 201 provides guidance and protection for the nail body 1, thereby avoiding the risk of the nail body 1 being pierced by the implant rod 2 and ensuring that the fixing performance of the nail body 1 is not affected. The assembly method is simple and easy to operate, and can realize batch assembly and carrying of multiple nail bodies 1 for a group of implant rods 2 and operating components 3 during surgery through rapid assembly, thereby avoiding waste of resources and saving surgical costs.

[0097] Before S1, the assembly method further includes assembling the implant rod 2 and the operating assembly 3, which specifically includes the following steps:

[0098] S01, clamp the implant rod 2 into the insertion hole 321 of the insertion seat mechanism 31, and relatively rotate the sliding rod 311 and the connecting sleeve 312 so that the implant rod 2 is blocked and limited by the blocking portion 3122; at the same time, the winding member 322 wound with the traction wire 4 and the handle member 323 are clamped and assembled through the buckle structure 324;

[0099] S02. Press the unlocking end of the locking piece 33 so that the locking end is outside the moving path of the sliding rod 311, and then insert the sliding rod 311 into the insertion hole 321 until it is adjusted to a suitable position, then release the unlocking end so that the locking end and the ratchet 3113 are engaged, and the assembly of the insertion seat mechanism 31 and the handle mechanism 32 is completed.

[0100] In practical applications, in order to further improve the convenience of users replacing the nail body 1 of the full suture anchor implantation device, the full suture anchor, the full suture anchor assembly device in the first embodiment and the winding member 322 can be preassembled. The details are as follows:

[0101] The nail body 1 of the full suture anchor is inserted into the clamping groove 101 of the clamping member 100, and the two traction wires 4 at both ends of the nail body 1 are respectively wound and connected to the winding member 322. The above components are used as a set of pre-assembled parts and are sterilized and packaged in advance to facilitate the operator to replace the nail body 1 for the full suture anchor implantation device. When it is necessary to assemble the nail body 1 to the full suture anchor implantation device, the above-mentioned pre-assembled parts are used to dock the implantation rod 2 of the full suture anchor implantation device with the clamping member 100 of the pre-assembled parts, so that the guide member 200 is inserted into the fixed groove 21 of the implantation rod 2. At the same time, the winding member 322 and the handle member 323 with the traction wire 4 are clamped and formed into a relaxed state. Then, the above-mentioned S3 and S4 operations are performed.

[0102] In the above S3 , the implant rod 2 moves along its own axis toward a direction away from the operating assembly 3 driven by the axial movement of the sliding rod 311 in the insertion hole 321 . Therefore, the axial movement of the implant rod 2 is achieved by pushing the insertion seat mechanism 31 .

[0103] In the above S4, during the continuous movement of the implant rod 2, the end of the implant rod 2 will abut against the arc-shaped transition structure between the fixed end and the free end of the clamping piece 201. At this time, no relative movement will occur between the implant rod 2 and the clamping piece 100. The abutment between the arc-shaped transition structure and the implant rod 2 plays a limiting role, preventing the tensioned traction line 4 from driving the entire suture anchor assembly device to move and failing to achieve the effect of only pulling the nail body 1.

[0104] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
