[0002] This application claims priority to Chinese patent application CN202411774714.8, filed on December 5, 2024, entitled “Full Suture Anchor Assembly Device, Full Suture Anchor Implantation Device and Assembly Method”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of medical device technology, and in particular to a full suture anchor assembly device, a full suture anchor implantation device, and an assembly method. Background Technology

[0004] In the field of medical devices, traditional bone anchors are made of rigid materials, resulting in hard contact with bone. Friction and impact between these rigid materials can cause secondary damage to the bone and even lead to surgical failure. Currently, some anchor implantation devices use fully suture anchors composed of medical textile yarns. These anchors are secured to the sutures by being pulled by traction threads. Fully suture anchors utilize the flexibility and overall deformability of their textile yarns to reduce bone damage from pre-drilling and avoid secondary bone damage.

[0005] However, because suture anchors are made of woven textile yarn, their assembly with the implant is quite difficult. Typically, the suture anchor and implant need to be pre-assembled and disassembled immediately during surgery; the suture anchor cannot be replaced. When multiple suture anchors are needed during surgery, each anchor requires a disposable implant, increasing surgical costs. Furthermore, the structure of suture anchors is not as dense as that of rigid anchors. During assembly, the implant rod often punctures the anchor body, damaging the anchor's structure and rendering it ineffective. It can also cause the anchor to detach, preventing the implant from delivering the anchor and leading to implantation failure. Summary of the Invention

[0006] The purpose of this application is to provide a full suture anchor assembly device, a full suture anchor implantation device, and an assembly method, which can solve the problems of existing implanters having non-replaceable full suture anchors, high surgical costs, and the implantation rod easily puncturing the full suture anchor during the pre-assembly process, causing it to fail and resulting in implantation failure.

[0026] S1. Insert the nail body with traction wires at both ends into the clamping groove of the clamping member, and the other end of the traction wire away from the nail body is wrapped and connected to the operating component, and is in a slack state.

[0027] S2. Connect the implant rod and the clamping member to insert the guide into the fixing groove of the implant rod;

[0028] S3. Move the implantation rod along its own axis toward a direction away from the operating component. The implantation rod drives the clamping member to move until the traction line changes from a slack state to a tensioned state.

[0029] S4. Continue to move the implant rod until the tensioned traction line pulls the nail body to squeeze the two clamping pieces away from each other so that they are locked into the clamping groove through the guide channel.

[0030] The beneficial effects of this application are:

[0031] The suture anchor assembly device provided in this application includes a clamping member and a guide member connected to the clamping member. The clamping member has a clamping groove for accommodating the anchor body of the suture anchor. The guide member is disposed at the opening of the clamping groove and includes two opposing clamping plates. The guide member can be inserted into the fixing groove of the implant rod. The two clamping plates are in a guiding state to form a guide channel, with both ends of the guide channel connecting the clamping groove and the fixing groove, respectively. When the guide member is in the guiding state, the anchor body can be clamped into the fixing groove through the guide channel. During this process, the plate-like clamping plates provide guidance and protection for the anchor body. The anchor body is finally clamped into the fixing groove of the implant rod through the guide channel without contacting the sharp end of the implant rod, avoiding the risk of the anchor body being punctured by the implant rod and damaging its structure, and ensuring that the fixing performance of the anchor body is not affected. Moreover, the anchor body clamped into the fixing groove allows the implant rod to effectively carry the anchor body, preventing the anchor body from falling out and ensuring smooth implantation. The full suture anchor assembly device has a simple structure and the implantation device is reusable. For surgeries that require multiple full suture anchors, the same implantation rod can be used to assemble the full suture anchors multiple times without the need for pre-assembly with the anchors or multiple replacements of the implantation rod, thus saving surgical costs.

[0032] The full-suture anchor implantation device provided in this application includes an implantation rod and an operating component. The implantation rod is detachably connected to the operating component and can move along its own axis. A fixing groove is formed at the end of the implantation rod away from the operating component. Two traction lines are respectively provided at both ends of the nail body, and the other ends of the two traction lines away from the nail body are connected to the operating component. When assembling the nail body in the above-mentioned full-suture anchor assembly device, the nail body with traction lines at both ends is first inserted into the clamping groove of the clamping member. The movement of the implantation rod along its own axis drives the clamping member to move away from the operating component. During this process, the slack traction lines are tensioned until the resulting tension force pulls the nail body to compress the two clamping plates away from each other to form a guide channel, and the nail body is then clamped in the fixing groove of the implantation rod through the guide channel. During the assembly process, the plate-like clamping plates provide guidance and protection for the nail body, avoiding the risk of the nail body being punctured by the implantation rod and ensuring that the fixing performance of the nail body is not affected. Moreover, the nail body is reliably clamped in the fixing groove, and the full-suture anchor implantation device can effectively carry the nail body, ensuring smooth implantation. The implant rod and operating components are reusable, and multiple nails can be implanted in a single suture anchor implantation device during surgery through rapid assembly, saving surgical costs.

[0033] The assembly method provided in this application utilizes the movement of the implant rod along its own axis to move the clamping components away from the operating components, thereby tensioning the slack traction wire. The tension force generated by the traction wire pulls the nail body, squeezing the two clamping plates away from each other to form a guide channel. The guide channel formed by the clamping plates provides guidance and protection for the nail body, avoiding the risk of the nail body being punctured by the implant rod and ensuring that the fixation performance of the nail body is not affected. The assembly method is simple and easy to operate. Multiple nail bodies can be assembled and carried in the operation by a set of implant rods and operating components during the operation, avoiding resource waste and saving surgical costs.

[0045] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 only used to explain this application, and should not be construed as limiting this application.

[0051] Example 1

[0052] As shown in Figures 1 to 4, this embodiment provides a full-suture anchor assembly device for assembling the anchor 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 both ends of the anchor body 1.

[0053] 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 has a clamping groove 101 for accommodating the anchor body 1. The guide member 200 is disposed at the opening of the clamping groove 101 and includes two clamping pieces 201 arranged opposite each other. The guide member 200 can be inserted into the fixing groove 21 of the implant rod 2. The two clamping pieces 201 are in a guiding state where they are far apart from each other to form a guiding channel. The two ends of the guiding 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 engaged in the fixing groove 21 through the guide channel. During this process, the sheet-like clamping piece 201 provides guidance and protection for the nail body 1. The nail body 1 is finally engaged in the fixing groove 21 through the guide channel, without contacting the sharp end of the implant rod 2, avoiding the risk of being punctured by the implant rod 2, and ensuring that the fixation performance of the nail body 1 is not affected. Moreover, the engagement of the nail body 1 in the fixing groove 21 allows the implant rod 2 to effectively carry the nail body 1, preventing the nail body 1 from falling out and ensuring smooth implantation. The full suture anchor assembly device has a simple structure and is reusable. In surgical applications that require multiple nail bodies 1, the same implant rod 2 can be assembled with nail bodies 1 multiple times. The full suture anchor implantation device to which the implant rod 2 belongs can be reused without pre-assembly with the nail body 1 or multiple replacements of the full suture anchor implantation device, saving surgical costs.

[0054] The movement of the nail body 1 can be achieved by traction operation via the traction line 4 or by manual traction operation. The mutual separation of the two clamping plates 201 can be achieved by a driving component that serves as a power source; in this embodiment, it can also be achieved by applying pressure through the nail body 1.

[0055] Specifically, the clamping groove 101 extends through both ends along a first direction to form two ports, with the nail body 1 passing through each port. The first direction is perpendicular to the length of the guide channel, ensuring the nail body 1 and the guide channel are perpendicular and facilitating rapid entry of the nail body 1 into the guide channel. This first direction is also the extension direction of the clamping groove 101. The extension direction of the guide groove 102 forms an angle with the extension direction of the clamping groove 101. The two ends of the nail body 1 are designed to withstand external force, causing the nail body 1 to press the two clamping pieces 201 away from each other to form the guide channel. External force pulls the two ends of the nail body 1 towards the clamping groove 101, pressing the two clamping pieces 201 away from each other during the movement to form the guide channel, and finally, the nail body 1 is secured within the clamping groove 101 via the guide channel. This eliminates the need for a driving component for the clamping pieces 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.

[0056] In order to make it easier to apply force to the nail body 1, in this embodiment, two traction lines 4 are respectively provided at both ends of the nail body 1. Pulling the traction lines 4 can apply force from both ends of the nail body 1 at the same time to move it, which is more convenient to operate. The traction lines 4 are evenly stressed, ensuring that the position of the traction lines 4 in the clamping groove 101 is more accurate.

[0057] The guide 200 has an initial state in which the two clamping pieces 201 are at least partially abutted against each other to close the guide channel and prevent the traction line 4 from falling off the clamp 100 due to guide channel failure. To ensure the closability of the guide channel, one end of the clamping piece 201 is fixed to the clamp 100 to form a fixed end, and the free end of the clamping piece 201 forms the guide channel.

[0058] The fixed end and free end of the clamping piece 201 have an arc-shaped transition structure. The free ends of the two clamping pieces 201 fit together, making the two clamping pieces 201 resemble a duckbill. On the one hand, the arc-shaped transition structure helps guide the nail body 1, reduces the resistance during the movement of the nail body 1, and avoids wear and deformation during assembly. On the other hand, the duckbill-shaped structure gives the guide 200 a certain degree of elasticity, which can better restore it from the guided state to the initial state.

[0059] To further improve the structural strength of the guide 200, the guide 200 also includes a fixing part 202, with both ends of the fixing part 202 connected to two clamping pieces 201, as shown in Figure 4. The fixing part 202 is at least partially embedded inside the clamping member 100. In this embodiment, to ensure the symmetry of the two clamping pieces 201 and to prevent the two clamping pieces 201 from being misaligned within the fixing groove 21, the fixing part 202 is a partial ring, with its notch connecting to the two clamping pieces 201 respectively; the fixing part 202 and the clamping groove 101 are coaxially arranged, and the radial dimension of the fixing part 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 part 202 are just positioned on both sides of the opening of the clamping groove 101.

[0060] Optionally, the two clamping plates 201 and the fixing part 202 are integrally formed by sheet metal processing, which has good structural strength. They are made of stainless steel sheet, which has good resistance to deformation, is not easy to rust, and meets the operation requirements of a sterile environment.

[0061] The guide 200 and the clamping part 100 are integrally formed and connected. The clamping part 100 is processed by injection molding, and the guide 200 is used as a pre-embedded part to realize the connection between the two during processing.

[0062] To improve the accuracy of the alignment between the implant rod 2 and the clamping piece 201, the clamping member 100 is also 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 into the guide groove 102, allowing the implant rod 2 to be inserted into the clamping groove 101. In this embodiment, the specific shape of the clamping member 100 is not limited. For example, the clamping member 100 is formed by two interconnected block structures. One block structure forms the clamping groove 101 and the guide groove 102, while the other block structure forms a hand-grip structure. This simplifies the structure, facilitates miniaturization and weight reduction, and makes it easy to operate by hand.

[0063] The cross-sectional dimension of the clamping groove 101 along the length direction is larger than that of the guide groove 102 along the length direction. Because the nail body 1 is in a free state when clamped in the clamping groove 101, the guide groove 102 with its smaller cross-sectional dimension can better adapt to the size of the implantation rod 2 and compress the nail body 1, making the nail body 1 present a ready-to-be-implanted state. Furthermore, the cross-sectional dimension of the guide groove 102 is adapted to the shape of the implantation rod 2, and the guide groove 102 provides good constraint on the implantation rod 2, preventing the implantation rod 2 from shifting position during the passage of the nail body 1 through the guide channel, thus affecting the assembly effect.

[0064] Example 2

[0065] This second embodiment provides a full-suture anchor implantation device. Using the full-suture anchor assembly device from the first embodiment, the anchor body 1 is assembled into the fixing groove 21 of the implantation rod 2. The full-suture anchor includes the anchor body 1 and two traction wires 4 connected to both ends of the anchor body 1. As shown in Figures 5 to 8, the full-suture anchor implantation device includes an implantation rod 2 and an operating component 3. The implantation rod 2 is detachably connected to the operating component 3 and can move along its own axis. The fixing groove 21 is located at the end of the implantation rod 2 away from the operating component 3. The other ends of the two traction wires 4 away from the anchor body 1 are both wound and connected to the operating component 3.

[0066] When assembling the nail body 1 using the full-suture anchor assembly device in Embodiment 1, the nail body 1, with traction wires 4 at both ends, is first 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. The movement of the implantation rod 2 along its own axis drives the clamping member 100 to move away from the operating component 3. During this process, the relaxed traction wire 4 is tensioned until the resulting tension pulls the nail body 1, squeezing the two clamping pieces 201 away from each other to form a guide channel, and then clamping it into the fixing groove 21 of the implantation rod 2 through the guide channel. During assembly, the sheet-like clamping pieces 201 provide guidance and protection for the nail body 1, avoiding the risk of the nail body 1 being punctured by the implantation rod 2, ensuring that the fixing performance of the nail body 1 is not affected; moreover, the nail body 1 is reliably clamped in the fixing groove 21, and the full-suture anchor implantation device can effectively carry the nail body 1, ensuring smooth implantation. The implant rod 2 and the operating component 3 are reusable. Multiple nail bodies 1 can be implanted in a single set of suture anchor implantation devices during surgery through rapid assembly, saving surgical costs.

[0067] The operating component 3 includes an insertion base mechanism 31 and a handle mechanism 32. The insertion base mechanism 31 is detachably connected to the end of the implant rod 2 away from the fixing groove 21. The insertion base mechanism 31 includes a sliding rod 311, one end of which is connected to the implant rod 2. The other end of the sliding rod 311 away from the implant rod 2 is movably constrained to the handle mechanism 32 along its own axis. The axial movement of the implant rod 2 is achieved by moving the sliding rod 311 along its own axis. The handle mechanism 32 facilitates handheld operation.

[0068] The handle mechanism 32 has an insertion hole 321, into which the sliding rod 311 is movably inserted. The operating component 3 also includes a locking member 33 movably connected to the handle mechanism 32. The locking member 33 has an unlocked state and a locked state. In the locked state, the locking member 33 is at least partially located on the movement path of the sliding rod 311 to abut and restrict the movement of the sliding rod 311. In the unlocked state, the locking member 33 is located outside the movement path. In this second embodiment, the locking member 33 is hinged to the handle mechanism 32 via a hinge shaft, with a locking end and an unlocking end formed on both sides of the hinge shaft, respectively.

[0069] The handle mechanism 32 has a locking hole 325 that connects to the insertion hole 321. The sliding rod 311 has multiple ratchet teeth 3113 spaced apart along the axial direction. When the locking member 33 is in the locked state, it rotates until the locking end passes through the locking hole 325 and engages with one of the ratchet teeth 3113 on the sliding rod 311. The sliding rod 311 can no longer move axially, thus 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 member 33. The locking end separates from the ratchet teeth 3113 of the sliding rod 311. At this time, the sliding rod 311 can move axially, thereby realizing the axial movement of the implant rod 2.

[0070] To maintain the reliability of the locking member 33 in the locked state, the operating component 3 also includes an elastic member 34. The elastic member 34 applies an elastic force to the unlocking end, causing the locking member 33 to always tend to rotate with the locking end toward the locking hole 325. Exemplarily, the elastic member 34 is a compression spring, with its two ends connected to the handle mechanism 32 and the unlocking end, respectively. The spring force of the compression spring always pushes the unlocking end upwards. Under the action of the spring force, the locking end is firmly pressed against the ratchet 3113 of the sliding rod 311. Moreover, after pressing the unlocking end to perform the unlocking operation, releasing the unlocking end allows the locking member 33 to quickly return to the locked state under the action of the spring force, preventing axial movement of the implanted rod 2 and accidental operation.

[0071] The handle mechanism 32 includes a winding member 322 and a handle member 323, which are detachably connected by a snap-fit ​​structure 324. Both ends of the winding member 322 have winding grooves for winding two traction wires 4, respectively, preventing the traction wires 4 from falling off and ensuring that the traction wires 4 can apply reliable traction force to the nail body 1. The handle member 323 has an insertion hole 321, into which a sliding rod 311 is movably inserted. The detachable connection between the handle member 323 and the winding member 322 facilitates assembly. The insertion seat mechanism 31 can be connected to the handle member 323 via the sliding rod 311, and the traction wire 4 carrying the nail body 1 can be wound onto the winding member 322. Then, the snap-fit ​​structure 324 can be used to snap the winding member 322 and the handle member 323 together, making assembly relatively convenient.

[0072] In practical applications, to further improve the convenience for users to replace the nail body 1 of the full suture anchor implantation device, the full suture anchor, the full suture anchor assembly device in Embodiment 1, and the winding component 322 can be pre-assembled. Specifically, the nail body 1 of the full suture anchor is inserted into the clamping groove 101 of the clamping component 100, and the two traction wires 4 at both ends of the nail body 1 are respectively wound and connected to the winding component 322. The above is a pre-assembled set, which is sterilized and packaged in advance to facilitate the operator to replace the nail body 1 of the full suture anchor implantation device. When it is necessary to assemble the nail body 1 into the full suture anchor implantation device, the above-mentioned pre-assembled component is used to align the implantation rod 2 of the full suture anchor implantation device with the clamping component 100 of the pre-assembled component, so that the guide 200 is inserted into the fixing groove 21 of the implantation rod 2. At the same time, the winding component 322 with the traction wire 4 wound around it and the handle 323 are snapped together. Then, push the implant rod 2 to move along its own axis to drive the clamping member 100 to move away from the operating component 3 until the nail body 1 squeezes the two clamping pieces 201 and is locked in the fixing groove 21 of the implant rod 2 through the guide channel.

[0073] It should be noted that, in the above process, since the axial movement of the implant rod 2 is driven by the insertion seat mechanism 31, in practical applications, the insertion seat mechanism 31 is pushed to drive the axial movement of the implant rod 2.

[0074] Specifically, the latching structure 324 includes a latching hole 3241 on the handle 323 and a latch 3242 on the winding member 322. The latching hole 3241 is open at both ends, and the latch 3242 is latched into the latching hole 3241, with its end protruding from the surface of the handle 323. The end has a protrusion, the cross-sectional size of which is larger than that of the latching hole 3241, to prevent the latch 3242 from coming loose from the latching hole 3241. To facilitate the passage of the larger protrusion through the latching hole 3241, at least a portion of the latch 3242 has a notch, forming two opposing half-latches. During latching, the two opposing half-latches are pressed together to bring them closer, allowing the protrusion to pass through the latching hole 3241 relatively easily. Then, the two half-latches are reset so that the protrusion is locked on one side of the latching hole 3241. Similarly, when it is necessary to disassemble the snap-fit ​​structure 324, the two opposing half snaps are squeezed together to bring them closer to each other, and the protrusions can pass through the snap-fit ​​hole 3241 more easily to separate the handle part 323 and the winding part 322.

[0075] The insert mechanism 31 also includes a connecting sleeve 312. One end of the sliding rod 311 is rotatably constrained to the connecting sleeve 312 about its own axis. The other end of the sliding rod 311 extending to the outside of the connecting sleeve 312 is 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.

[0076] To achieve a rotatable constraint connection for the sliding rod 311, the sliding rod 311 has a radially protruding limiting boss. The connecting sleeve 312 includes two interconnected first sleeves 3124 and second sleeves 3125. The first sleeves 3124 and second sleeves 3125 together form a mounting cavity. The sliding rod 311 passes through the second sleeve 3125, so that the limiting boss is located within the mounting cavity. Then, the first sleeves 3124 and second sleeves 3125 are connected together. Under the limiting action of the limiting boss, the sliding rod 311 will not detach from the connecting sleeve 312 and can rotate around its own axis. The first sleeves 3124 and second sleeves 3125 can be fixed by welding or formed by threaded connection to create a detachable structure.

[0077] To achieve a detachable connection between the insertion seat mechanism 31 and the implant rod 2, the end of the connecting sleeve 312 away from the handle mechanism 32 has an installation port 3121, and the end of the sliding rod 311 away from the handle mechanism 32 has an insertion groove 3111, which connects to the installation port 3121. The implant rod 2 includes a rod body 22 and an insertion part 23. The cross-sectional dimension of the insertion part 23 is larger than that of the rod body 22, and the insertion part 23 can be inserted into the insertion groove 3111 through the installation port 3121. A blocking part 3122 is provided at the installation port 3121. The sliding rod 311 and the connecting sleeve 312 can rotate relative to each other so that the blocking part 3122 at least partially blocks the insertion part 23 to prevent the insertion part 23 from disengaging from the insertion groove 3111. In this embodiment, the blocking portion 3122 consists of two opposing bosses extending radially toward the axis of the connecting sleeve 312. The insertion portion 23 can pass through the mounting opening 3121 and be inserted into the insertion groove 3111. Then, through the relative rotation of the sliding rod 311 and the connecting sleeve 312, the insertion portion 23 is rotated until it is at least partially blocked by the blocking portion 3122. Under the restriction of the blocking portion 3122, the insertion portion 23 will not disengage from the insertion groove 3111, thus realizing the connection between the insertion seat mechanism 31 and the implant rod 2. Accordingly, when it is necessary to remove the implant rod 2, the relative rotation of the sliding rod 311 and the connecting sleeve 312 causes the insertion portion 23 to rotate to an angle where it is not blocked by the blocking portion 3122, thereby removing the implant rod 2.

[0078] The relative rotation of the sliding rod 311 and the connecting sleeve 312 can be achieved by holding the sliding rod 311 and rotating the connecting sleeve 312; or by holding the connecting sleeve 312 and rotating 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 their usage habits and operating space.

[0079] To restrict the relative position of the blocking part 3122 and the insertion part 23 and ensure convenient assembly and disassembly, one of the connecting sleeve 312 and the sliding rod 311 is provided with a limiting groove 3112, and the other is provided with a limiting protrusion. The limiting protrusion is slidably embedded in the limiting groove 3112. The two side walls of the limiting groove 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 insertion part 23 can be inserted into the insertion slot 3111 through the mounting port 3121. When the limiting protrusion abuts against the other of the two side walls, the blocking part 3122 at least partially blocks the insertion part 23. The cooperation between the limiting protrusion and the limiting slide 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. At one extreme position, the insertion part 23 can pass through the mounting port 3121 and be inserted into the insertion groove 3111 or disengage from the insertion groove 3111. At the other extreme position, the insertion part 23 is blocked by the blocking part 3122 and stably locked in the insertion groove 3111.

[0080] Once the relative positions of the sliding rod 311 and the connecting sleeve 312 have rotated to their positions, the locking member 33 engages with the ratchet 3113 to lock the sliding rod 311. This prevents the sliding rod 311 from moving axially and also prevents it from rotating, thus completely restricting its movement.

[0081] Example 3

[0082] This third embodiment provides a full-suture anchor implantation device, which uses the full-suture anchor assembly device from the first embodiment to assemble the anchor body 1 into the fixing groove 21 of the implantation rod 2. The full-suture anchor implantation device provided in this third embodiment is basically the same as the full-suture anchor implantation device in the second embodiment, with only some differences in the settings. This embodiment will not repeat the same content as in the second embodiment.

[0083] In this embodiment, as shown in Figures 9 and 10, the handle mechanism 32 has an adjustment hole 326 extending through both ends. The sliding rod 311 is movably inserted into the adjustment hole 326. The adjustment hole 326 is configured to restrict the sliding rod 311 from rotating around its own axis; that is, the sliding rod 311 can move axially but cannot rotate within the adjustment hole 326. An adjustment thread 3114 is provided at the other end of the sliding rod 311 away from the implant rod 2.

[0084] The operating component 3 also includes an adjusting handwheel 35 and a striking element 36. The adjusting handwheel 35 is rotatably connected to the handle mechanism 32, which has a rotating groove. The adjusting handwheel 35 is rotatably constrained within the rotating groove. The adjusting handwheel 35 has a through adjusting threaded hole 351, and is threadedly connected to the sliding rod 311 via the adjusting threaded hole 351 to drive the sliding rod 311 to move axially. When the adjusting handwheel 35 is rotated, the sliding rod 311, constrained within the adjusting hole 326, moves axially, thereby driving the implanted rod 2 to move axially. The axial movement of the sliding rod 311 is achieved through a threaded connection structure, eliminating the need for an axial locking structure. The self-locking of the adjusting threaded hole 351 and the adjusting thread 3114 enables the axial locking of the sliding rod 311. Moreover, compared to manual adjustment, adjusting the axial position of the sliding rod 311 by rotating the adjusting handwheel 35 offers advantages such as high adjustment precision and accurate positioning.

[0085] Specifically, at least a portion of the adjusting hole 326 is a rectangular cross-section hole, and at least a portion of the sliding rod 311 located within the adjusting 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.

[0086] The sliding rod 311 extends through the adjusting threaded hole 351 to the adjusting handwheel 35 to connect with the striking element 36. The sliding rod 311 and the striking element 36 can be connected through interference fit, threaded connection, or other structures. When the nail body 1 is driven in, the striking element 36 bears the driving force and then transmits the driving force to the nail body 1 via the sliding rod 311 and the implantation rod 2. Compared to directly driving the adjusting handwheel 35 during implantation, driving the striking element 36 reduces the damage to the threaded connection between the adjusting handwheel 35 and the sliding rod 311 caused by the driving force, reduces the damage rate of the operating component 3, and ensures the repeatability and efficiency of the operating component 3.

[0087] It should be noted that, in this embodiment, since the sliding rod 311 cannot rotate around its own axis, when installing the implant rod 2, the relative rotation between the sliding rod 311 and the connecting sleeve 312 is only achieved by rotating the connecting sleeve 312.

[0088] Example 4

[0089] This application provides an assembly method in Embodiment 4, which uses the full-suture anchor assembly device in Embodiment 1 to assemble the full-suture anchor implantation device in Embodiment 2 or Embodiment 3, and assembles the nail body 1 into the fixing groove 21 of the implantation rod 2.

[0090] The assembly method includes the following steps:

[0091] S1. The nail body 1 with traction wires 4 at both ends is inserted 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 slack state.

[0092] S2. Connect the implant rod 2 and the clamp 100 so that the guide 200 is inserted into the fixing groove 21 of the implant rod 2.

[0093] S3. Move the implant rod 2 along its own axis toward a direction away from the operating component 3. The implant rod 2 drives the clamping component 100 to move until the traction line 4 changes from a relaxed state to a tense state.

[0094] S4. Continue to move the implantation rod 2 until the tensioned traction line 4 pulls the nail body 1 to squeeze the two clamping pieces 201 away from each other so that they can be locked into the clamping groove 101 through the guide channel.

[0095] The assembly method utilizes the movement of the implant rod 2 along its own axis to move the clamping component 100 away from the operating component 3, thereby tensioning the slack traction line 4. The tension force generated by the traction line 4 pulls the nail body 1 to compress the two clamping plates 201 away from each other to form a guide channel. The guide channel formed by the clamping plates 201 provides guidance and protection for the nail body 1, avoiding the risk of the nail body 1 being punctured by the implant rod 2 and ensuring that the fixation performance of the nail body 1 is not affected. The assembly method is simple and easy to operate. Through rapid assembly, multiple nail bodies 1 can be assembled and carried in batches during the operation by a set of implant rods 2 and operating components 3, avoiding resource waste and saving surgical costs.

[0096] Prior to S1, the assembly method also includes the assembly of the implant rod 2 and the operating component 3, specifically including the following steps:

[0097] S01. Insert the implant rod 2 into the insertion hole 321 of the insertion base mechanism 31, and rotate the sliding rod 311 and the connecting sleeve 312 relative to each other so that the implant rod 2 is blocked and limited by the blocking part 3122; at the same time, the winding part 322 with the traction wire 4 wrapped around it and the handle part 323 are snapped together by the buckle structure 324.

[0098] S02. Press the unlocking end of the locking member 33 so that the locking end is outside the movement path of the sliding rod 311. 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 engage, and complete the assembly of the insertion seat mechanism 31 and the handle mechanism 32.

[0099] In practical applications, to further improve the convenience for users to replace the nail body 1 of the full-suture anchor implantation device, the full-suture anchor, the full-suture anchor assembly device in Embodiment 1, and the winding component 322 can be pre-assembled. Specifically:

[0100] 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 pre-assembled as a complete set and sterilized and packaged in advance to facilitate the operator to replace the nail body 1 of the full suture anchor implantation device. When it is necessary to assemble the nail body 1 into the full suture anchor implantation device, the above-mentioned pre-assembled component is used to align the implantation rod 2 of the full suture anchor implantation device with the clamping member 100 of the pre-assembled component, so that the guide member 200 is inserted into the fixing groove 21 of the implantation rod 2. At the same time, the winding member 322 with the traction wires 4 wound around it and the handle member 323 are snapped together and made into a relaxed state. Then, the above-mentioned operations S3 and S4 are performed.

[0101] In S3 above, the movement of the implant rod 2 along its own axis toward the direction away from the operating component 3 is driven by the axial movement of the sliding rod 311 within the insertion hole 321. Therefore, the axial movement of the implant rod 2 is achieved by the push insertion seat mechanism 31.

[0102] 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, there will be no relative movement 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 full-suture anchor assembly device to move and thus failing to achieve the effect of only pulling the nail body 1.

[0103] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the scope of protection of this application. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
