Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a detachable implantation system for an anchor clip and an anchor. Background Technology
[0002] Currently, most implantation devices for suture anchor implantation systems are disposable, which not only increases medical costs but also wastes medical resources.
[0003] Existing detachable anchor implantation systems enable the reuse of the anchor implanter. However, the loading device used to store the anchors is complex in structure, difficult to manufacture and assemble, and has high manufacturing costs; moreover, installing the anchors from the loading device onto the anchor implanter is difficult and time-consuming. Utility Model Content
[0004] The purpose of this invention is to provide a separate implantation system for anchor clips and anchors, so as to enable the reusability of the anchor installer, simplify the structure of the anchor loading device, reduce manufacturing costs, and improve the assembly efficiency of the anchor and the anchor installer.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] Anchor clamp, comprising:
[0007] Two clips are pressed together to form the anchor clamp, and the anchor clamp has an anchor cavity for holding the anchor.
[0008] The anchor clamp includes a main structure and a clamping structure located at one end of the main structure. The anchor cavity extends from the main structure to the clamping structure. The clamping structure is fastened together so that the clamping structure can open and release the anchor under the thrust of the anchor.
[0009] As an alternative to the anchor clamp, the main structure is U-shaped, the clamping structure is located in the cavity of the main structure, and the middle part of the clamping structure near the bottom of the cavity is connected to the main structure to form the anchor cavity.
[0010] As an optional solution for the anchor clamp, the clamping structure is connected by a snap-fit structure of a protrusion and a groove, and the protrusion and groove are symmetrically distributed on both sides of the anchor cavity.
[0011] As an optional embodiment of the anchor clamp, the anchor clamp also has a guide channel coaxially arranged with the anchor cavity, and a limiting groove is provided in the guide channel.
[0012] As an optional embodiment of the anchor clip, the anchor clip is further provided with a suture management unit, and there are two suture management units located on the main structure;
[0013] Two suture management units are symmetrically arranged on both sides of the anchor cavity. After the suture of the anchor passes through the anchor, both ends are fixed in the suture management unit.
[0014] As an optional solution for the anchor clip, the suture management unit is a suture guide channel formed by multiple strip-shaped protrusions arranged in a staggered manner. The strip-shaped protrusions are located on one of the two clips. The suture is wound between the sidewalls of the strip-shaped protrusions under the guidance of the suture guide channel and is clamped and fixed by the two clips.
[0015] As an optional solution for the anchor clip, two sets of guide structures are symmetrically arranged on the concave side of the main structure, and the two sets of guide structures are arranged one-to-one with the two suture management units;
[0016] The guiding structure is used to guide the suture passing through the anchor to a side away from the anchor cavity, so that the suture is wound from the outside to the inside along the suture guiding path.
[0017] As an alternative to the anchor clip, the guiding structure includes a guide block located outside the corner of the cavity. The guide block is used to guide the suture passing through the anchor to the outside of the cavity sidewall so as to wrap around a strip-shaped protrusion located outside the suture guiding passage.
[0018] As an optional embodiment of the anchor clip, the guiding structure further includes a guide post located on the outer side wall of the cavity. The tangent of the guide post on the side away from the anchor cavity is on the same straight line as the outer side wall of the strip-shaped protrusion located outside the suture guiding passage. The suture passes through the guide block, bypasses the guide post, and enters the suture guiding passage.
[0019] As an alternative to the anchor clip, the clip is a rigid, transparent sheet;
[0020] And / or, the clip is made of a biosafety material, the biosafety material being a base material of polyethylene terephthalate or medical-grade polycarbonate.
[0021] As an alternative to the anchor clamp, the main structure has a first fixing structure on the side away from the clamping structure for fixing to the anchor.
[0022] A detachable anchor insertion system includes an anchor inserter and an anchor clamp as described in any of the above embodiments, the anchor inserter being able to engage with an anchor in the anchor clamp and eject the anchor from the anchor clamp.
[0023] As an alternative to the detachable implantation system for the anchor, the implanter includes a handle and an implantation rod. One end of the handle is provided with a clamping groove adapted to the anchor clamp. The implantation rod is fixed to the bottom of the clamping groove. The anchor clamp can be clamped in the clamping groove. A second fixing structure is provided in the clamping groove.
[0024] As an alternative to the separate implantation system for the anchor, the implantation rod has an insertion groove at the end away from the handle, and the insertion groove is inserted into the anchor.
[0025] And / or, the end of the implant rod away from the handle is symmetrically provided with limiting protrusions.
[0026] The beneficial effects of this utility model are:
[0027] The anchor clamp provided by this utility model consists of two clamping pieces pressed together to form an anchor clamp with an internal anchor cavity. The anchor clamp includes a main structure and a clamping structure located at one end of the main structure. The anchor cavity extends from the main structure to the clamping structure, and the clamping structure is fastened together. Clamping the anchor within the anchor cavity provides sufficient mechanical support, ensuring the stability of the anchor fixation when the clamping structure is fastened together. Furthermore, when the anchor is pushed out, the fastening connection of the clamping structure is released under the compressive force of the anchor, allowing the two clamping pieces of the clamping structure to open in a shell-like shape, thus facilitating the smooth release of the anchor. This anchor clamp has a simple structure, is easy to manufacture, reduces manufacturing costs, and improves the assembly efficiency of the anchor and the anchor installer.
[0028] By incorporating two suture management units within the anchor clamp, both ends of the suture passing through the anchor are stored separately, enabling the joint storage of both the anchor and the suture in anchors with sutures. Furthermore, the suture management unit is configured as a suture guiding path formed by multiple staggered strip-shaped protrusions. Guided by this path, the suture winds around the sidewalls of the protrusions and is secured by two clamps. When the anchor is ejected, the sutures on both sides are released simultaneously along their respective guiding paths, reducing the risk of suture shifting to one side or detaching from the anchor. Moreover, the suture management unit relies on the staggered arrangement of the strip-shaped protrusions, integrally formed with the clamps, eliminating the need for additional moving parts and reducing the risk of mechanical failure and debris generation.
[0029] The detachable anchor implantation system provided by this utility model features a simple anchor clip structure, low manufacturing cost, and quick assembly and disassembly between the implanter and the anchor clip, ensuring high surgical efficiency. Furthermore, the implanter is reusable, while only the anchor clip is a disposable consumable, reducing medical waste and contributing to environmental protection. Attached Figure Description

[0046] The embodiments of this utility model are described in detail below. Examples of the 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0050] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0051] Anchors include suture anchors and non-suture anchors. Suture anchors consist of an anchor body and a suture. The anchor body is made of biocompatible materials, such as polylactic acid, polyetheretherketone, or titanium alloy, and can remain stable in the human body for a long time. The suture is a non-absorbable surgical suture, usually made of high-strength polyester, ultra-high molecular weight polyethylene, or polypropylene. The number of sutures can be one or more depending on the specific needs. Non-suture anchors consist only of an anchor body and rely on mechanical locking for fixation after implantation.
[0052] During anchor implantation, a stapler is typically used. The anchor and stapler are assembled as a single unit, and the stapler is then inserted into the surgical site. To enable the reuse of the stapler, existing technologies incorporate an anchor loading device to separately store the anchors. Before surgery, the stapler is inserted into the anchor loading device and assembled with the anchor. The anchor is then pushed out of the anchor loading device by the stapler and inserted into the surgical site. However, existing anchor loading devices are structurally complex, increasing manufacturing costs, and the assembly process between the stapler and anchor is complicated, affecting surgical efficiency.
[0053] To address the aforementioned technical problems, Embodiment 1 of this utility model provides an anchor clip for storing anchors with or without wires. It has a simple structure and low manufacturing cost. Embodiment 2 provides a separable anchor implantation system, in which the anchor and the implanter can be packaged separately, enabling the reuse of the implanter and reducing medical waste. It also reduces processing costs and improves the assembly efficiency of the anchor and implanter.
[0054] Example 1:
[0055] like Figures 1-3 As shown, this embodiment provides an anchor clamp, including two clamping pieces 1, which are pressed together to form the anchor clamp. The anchor clamp has an anchor cavity 13 for clamping an anchor 2. The anchor clamp includes a main structure 11 and a clamping structure 12 located at one end of the main structure 11. The anchor cavity 13 extends from the main structure 11 to the clamping structure 12. The clamping structure 12 is fastened together so that it can open and release the anchor 2 under the thrust of the anchor 2.
[0056] The anchor 2 is clamped within the anchor cavity 13, providing sufficient mechanical support and ensuring the stability of the anchor 2 when the clamping structure 12 is engaged. Furthermore, when the anchor 2 is pushed out, the engagement of the clamping structure 12 is released under the compressive force of the anchor 2, allowing the two clamping plates 1 of the clamping structure 12 to open into a shell shape, thus facilitating the smooth release of the anchor 2. This anchor clamp has a simple structure, is easy to manufacture, reduces manufacturing costs, and improves the assembly efficiency of the anchor 2 and the anchor inserter 4.
[0057] In one embodiment, the clip 1 is a rigid, transparent sheet, formed by hot or cold pressing. Two clips 1 are formed by folding a single sheet in half, and then joined together at certain points using a pressing process to form a stable anchor clip. A gap is left between the two clips 1 to provide space for the storage and release of the anchor 2 and suture 3. Furthermore, the anchor clip is transparent, making it easy to observe the alignment of the anchor 4 with the anchor 2 and the movement of the anchor 2 during assembly of the stapler 4 and the anchor 2. This reduces the possibility of misoperation, improves the assembly efficiency of the anchor 2 and the stapler 4, and further ensures the safety of the surgery.
[0058] In other embodiments, the two clips 1 may also be separate structures made of two rigid transparent sheets.
[0059] Furthermore, the clip 1 is made of biosafety material, which is based on polyethylene terephthalate or medical-grade polycarbonate. Even if debris generated during the insertion of the anchor 2 from friction with the clip 1 adheres to the anchor 2 and is implanted into the body, it will not cause postoperative inflammatory reactions, further ensuring the safety of the surgery.
[0060] Specifically, the clamping pieces 1 are symmetrical on both sides of the central axis. Both clamping pieces 1 are provided with grooves that are adapted to the shape of the anchor nail 2 with the central axis as the axis. After the two clamping pieces 1 are pressed together, the two grooves are joined to form the anchor nail cavity 13 for clamping the anchor nail 2.
[0061] In one embodiment, the main structure 11 is U-shaped, and the clamping structure 12 is disposed within the cavity of the main structure 11. The middle part of the clamping structure 12 near the bottom of the cavity is connected to the main structure 11 to form an anchor cavity 13. This arrangement ensures that the clamping structure 12 is only connected to the main structure 11 in the middle, and remains separated from the main structure 11 in the circumferential direction. When the anchor 2 is subjected to a pushing force, the two clamping pieces 1 of the clamping structure 12 break free from their latching connection, making it easier to open, and the opening angle is unrestricted, which is more conducive to releasing the anchor 2.
[0062] In other embodiments, the main structure 11 may also be configured as a rectangle, with the clamping structure 12 connected to one side of the rectangular main structure 11, and only the middle part of the clamping structure 12 near the main structure 11 is connected to the main structure 11.
[0063] In one embodiment, the clamping structure 12 is fastened together by a locking protrusion 121 and a locking groove 122, and the locking protrusion 121 and locking groove 122 are symmetrically distributed on both sides of the anchor cavity 13. A locking protrusion 121 is provided on one of the clamping pieces 1 of the clamping structure 12, and a locking groove 122 is provided on the other clamping piece 1 corresponding to the locking protrusion 121. Lightly pressing one clamping piece 1 presses the locking protrusion 121 into the locking groove 122, thus achieving the fastening connection of the clamping structure 12. When the anchor 2 is pushed out, the locking protrusion 121 breaks free from the locking groove 122, and the two clamping pieces 1 of the clamping structure 12 open in a direction away from each other, thus releasing the anchor 2.
[0064] Specifically, the locking protrusion 121 is a cylindrical protrusion, and the locking groove 122 is a cylindrical groove. A locking protrusion 121 and a locking groove 122 are fitted on each side of the anchor cavity 13.
[0065] Of course, in other embodiments, the shapes of the protrusion 121 and the slot 122 can also be other shapes such as quadrangular prisms or hexagonal prisms.
[0066] In one embodiment, the anchor clamp also has a guide channel 14 coaxially arranged with the anchor cavity 13, and a limiting groove 15 is provided in the guide channel 14. The guide channel 14 is used to guide the implantation rod 42 of the implanter 4 into the anchor clamp and to engage with the anchor 2 in the anchor cavity 13. The limiting groove 15 can restrict the insertion direction of the implantation rod 42 to ensure accurate docking between the implantation rod 42 and the anchor 2.
[0067] Specifically, both clips 1 have arc-shaped grooves centered on the central axis. After the two clips 1 are pressed together, they form a guide channel 14 that matches the outer periphery of the implant rod 42. A limiting groove 15 is also provided in the arc-shaped groove to cooperate with the limiting structure on the outer periphery of the implant rod 42 and restrict the insertion direction of the implant rod 42.
[0068] In one embodiment, such as Figure 1 and Figure 4 As shown, the anchor clamp also includes two suture management units 16, located on the main structure 11. The two suture management units 16 are symmetrically arranged on both sides of the anchor cavity 13. After the suture 3 of the anchor with thread passes through the anchor 2, both ends are fixed within the suture management units 16. For the anchor 2 with thread, both ends of the suture 3 passing through the anchor 2 are stored in the two suture management units 16 respectively. When the anchor 2 is pushed out, it can synchronously release the suture 3 at both ends, realizing the storage and automatic release of the suture 3.
[0069] In one embodiment, the suture management unit 16 is a suture guiding channel formed by a plurality of staggered strip-shaped protrusions 161. The strip-shaped protrusions 161 are located on one of the two clips 1. The suture 3 is wound around the sidewalls of the strip-shaped protrusions 161 under the guidance of the suture guiding channel and is held and fixed by the two clips 1. When storing the anchor 2 with suture, the two clips 1 are first unfolded, and the anchor 2 is placed in the groove of one of the clips 1. After the suture 3 passes through the anchor 2, its two ends are wound in an S-shape around the sidewalls of the strip-shaped protrusions 161 along the suture guiding channel. Then the two clips 1 are pressed together, and the suture 3 is fixed by the inner walls of the two clips 1. When the anchor 2 is pushed out, the sutures 3 on both sides of the anchor 2 are released synchronously along their respective suture guiding channels, reducing the risk of the suture 3 shifting to one side or detaching from the anchor 2. When the anchor 2 is inserted into the surgical position 100, the suture 3 is released smoothly under the constraint of the appropriate friction of the suture guiding channel, reducing potential damage to surrounding tissues.
[0070] Furthermore, the existing double ratchet structure used to release the suture 3 may not release the suture 3 simultaneously due to the inconsistent rotation of the two ratchets. This poses a risk that the suture 3 may shift to one side or even detach from the anchor 2. Additionally, the ratchet may generate debris due to impacts from components during rotation. If this debris is implanted into the body along with the suture 3, it could cause postoperative inflammation. In contrast, the suture management unit 16 in the anchor clip provided in this embodiment relies on the staggered arrangement of strip-shaped protrusions 161 integrally formed with the clip 1, eliminating the need for additional moving parts and reducing the risk of mechanical failure and debris generation.
[0071] In one embodiment, two sets of guide structures 17 are symmetrically arranged on the concave side of the main structure 11, and the two sets of guide structures 17 are corresponding one-to-one with the two suture management units 16. The guide structures 17 are used to guide the suture 3 passing through the anchor 2 to the side away from the anchor cavity 13, so that the suture 3 is wound from the outside to the inside along the suture guide path. The guide structures 17 cause the suture 3 exiting the anchor 2 to be offset outward, forming an S-shaped winding path from the outside to the inside, effectively avoiding friction between the suture 3 and the anchor cavity 13.
[0072] Specifically, the guiding structure 17 includes a guiding block 171 located on the outer side of the corner of the cavity. The guiding block 171 guides the suture 3 passing through the anchor 2 to the outer side wall of the cavity, so as to wrap around the strip-shaped protrusion 161 located on the outer side of the suture guiding passage. The guiding block 171 extends from the outer side of the bottom wall of the cavity to the outer side wall of the cavity to maximize the guiding length of the suture 3 by the guiding block 171, ensuring that the suture 3 passing through the anchor 2 has a certain tension and will not loosen.
[0073] In this embodiment, the guide block 171 is irregularly shaped and its surface is an arc surface. The arc surface has a guiding and supporting effect on the sewing thread 3, which reduces the friction between the sewing thread 3 and the guide block 171 and ensures that the sewing thread 3 has good tension.
[0074] Furthermore, the guiding structure 17 also includes a guide post 172 located on the outer sidewall of the concave cavity. The tangent of the guide post 172 on the side away from the anchor cavity 13 is on the same straight line as the outer sidewall of the strip-shaped protrusion 161 located outside the suture guiding passage. The suture 3 enters the suture guiding passage after passing through the guide block 171 and the guide post 172. By setting the guide post 172, whose tangent on the side away from the anchor cavity 13 is aligned with the outer sidewall of the strip-shaped protrusion 161, the suture 3 naturally conforms to the sidewall of the strip-shaped protrusion 161 in the suture guiding passage after turning around the guide post 172, eliminating stress concentration caused by abrupt changes in the winding path. The guide block 171 and the guide post 172 form a "dual-pivot" guiding mechanism, which decomposes the winding motion of the suture 3 into a pre-guiding segment and a fine positioning segment through two contact points, effectively preventing the risk of anchor 2 displacement caused by suture 3 slack.
[0075] In one embodiment, the main structure 11 has a first fixing structure on the side away from the clamping structure 12 for fixing to the stapler 4. The first fixing structure is a positioning bead 18, which cooperates with the stapler 4 to fix the main structure 11 to the stapler 4.
[0076] The anchor clip provided in this embodiment consists of two clips 1 pressed together to form an anchor cavity 13, a guide channel 14, and a suture guide path. This allows for the storage of anchors 2 and sutures 3, and guides the implanter 4 to precisely align with the anchor 2. Its simple structure facilitates the assembly of the implanter 4 and anchor 2, making the anchor clip a disposable consumable with low manufacturing costs. Furthermore, the lightweight anchor clip improves the surgeon's comfort. The suture guide path is formed by multiple staggered strip-shaped protrusions 161 integrally formed with the clips 1, eliminating the need for other parts and preventing debris generation due to friction, thus reducing the risk of postoperative inflammation. The two clips 1 hold and fix the suture 3, effectively preventing suture displacement or entanglement. When the anchor 2 is pushed out, the suture 3 can be released along the suture guide path, maintaining good tension distribution and contributing to a higher surgical success rate. The transparent anchor clip allows the surgeon to observe the anchor 2 and suture 3, reducing the possibility of misoperation and further ensuring surgical safety.
[0077] Example 2:
[0078] like Figure 5 and Figure 6As shown, this embodiment provides a detachable implantation system for anchors, including an implanter 4 and an anchor clamp provided in Embodiment 1. The implanter 4 can be inserted into the anchor 2 in the anchor clamp and push the anchor 2 out of the anchor clamp.
[0079] Specifically, the stapler 4 includes a handle 41 and an implantation rod 42. One end of the handle 41 is provided with a clamping groove 411 adapted to the anchor clip. The implantation rod 42 is fixed to the bottom of the clamping groove 411, and the anchor clip can be clamped in the clamping groove 411. A second fixing structure is provided in the clamping groove 411. Both the handle 41 and the implantation rod 42 are made of stainless steel and can be repeatedly sterilized, thus enabling reuse. When the implantation rod 42 is inserted into the guide channel 14 of the anchor clip and pushes out the anchor 2, the anchor clip can be clamped in the clamping groove 411. After the implantation rod 42 inserts the anchor 2 into the surgical position 100, it moves in the opposite direction to the implantation direction, which can completely release the suture 3 in the anchor clip. After the suture 3 is completely released, the anchor clip is removed from the handle 41, and the next anchor clip can be used for implantation of the anchor 2, thus enabling the stapler 4 to be reused.
[0080] Specifically, the clamping groove 411 is a flat groove adapted to the anchor clip, and the second fixing structure is a fixing groove (not shown in the figure). When the anchor clip enters the clamping groove 411, the positioning bead 18 on the anchor clip slides into the fixing groove to fix the anchor clip and the handle 41.
[0081] In this embodiment, three positioning beads 18 are provided on each side of the guide channel 14. Correspondingly, three fixing grooves are also provided on each side of the clamping groove 411. The six positioning beads 18 and the six fixing grooves are matched one-to-one to ensure the stability of the anchor clip and the handle 41.
[0082] Specifically, the end of the implant rod 42 away from the handle 41 is provided with a insertion groove 421, which is inserted into the anchor 2. The tail end of the anchor 2 is hexagonal prism-shaped, and the insertion groove 421 is configured as a hexagonal prism groove adapted to the hexagonal prism shape.
[0083] A limiting protrusion 422 is symmetrically provided at the end of the implant rod 42 away from the handle 41. The limiting protrusion 422 cooperates with the limiting groove 15 in the guide channel 14 to limit the insertion direction of the insertion slot 421, so as to ensure that the tail end of the hexagonal prism-shaped anchor 2 can be inserted into the hexagonal prism slot.
[0084] The detachable anchor implantation system provided in this embodiment features a simple anchor clip structure, low manufacturing cost, and quick assembly and disassembly between the implanter 4 and the anchor clip, ensuring high surgical efficiency. Furthermore, the implanter 4 is reusable, while only the anchor clip is a disposable consumable, reducing medical waste and contributing to environmental protection. Additionally, the lightweight design of the anchor clip in this detachable anchor implantation system reduces processing difficulty and manufacturing costs, enabling mass production and further lowering treatment costs for patients.
[0085] like Figures 7-10 As shown, the method of using the detachable implantation system for anchors provided in this embodiment is as follows:
[0086] After aligning the limiting protrusion 422 on the implantation rod 42 of the stapler 4 with the limiting groove 15 in the guide channel 14 of the anchor clamp, insert the implantation rod 42 into the guide channel 14 to accurately align the insertion groove 421 with the tail end of the anchor 2, so that the anchor 2 is inserted into the insertion groove 421. Push the implantation rod 42 with the handle 41 to push the anchor 2 out of the anchor clamp. The anchor 2 drives the suture 3 to be released from the suture guide passage until the anchor clamp moves into the clamping groove 411 of the handle 41. After the positioning bead 18 slides into the fixing groove, the anchor clamp is fixed on the handle 41. After accurately locating the implantation point, tap or rotate the handle 41 of the stapler 4 to push the anchor 2 into the surgical position 100. After the implantation is completed, pull the implantation rod 42 in the opposite direction of the implantation direction with the handle 41. After the implantation rod 42 is disengaged from the anchor 2, the stapler 4 continues to move in the opposite direction of the implantation direction to completely release the suture 3 in the anchor clamp. After the suture 3 is completely released, remove the anchor clip from the implanter 4 and discard it. Continue to repeat the above operation for the next anchor clip through the implanter 4 until all anchors 2 are implanted.
