The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower than the second feature in horizontal height.

[0057] The technical solutions of the present application will be further described below in conjunction with the drawings and through specific embodiments.

[0058] The split implantation system of the anchor nail includes a storage box and an inserter, and the storage box of the anchor nail is used for storing the anchor nail separately, so that the anchor nail can be arranged separately from the inserter. During the operation, the inserter is inserted into the storage box of the anchor nail to assemble with the anchor nail, and after the inserter is assembled with the anchor nail, the anchor nail is pushed out of the storage box, and the storage box is fixed with the inserter after moving to a set position, so that the medical staff can implant the anchor nail through the inserter.

[0059] The inserter is made of metal material, and one inserter can cooperate with the storage boxes of different anchor nails to realize the assembly of the inserter and the anchor nail and the implantation of the anchor nail, so that the inserter can be reused.

[0060] In the prior art, the storage box of the anchor nail is a three-dimensional structure, which is usually made of a high polymer material, and has a complex anchor nail storage structure and a suture storage structure inside. On the one hand, due to the high hygiene standard of medical devices, the complex structure inside the existing storage box causes a cleaning dead angle during sterilization, and the gap and dead angle of the internal structure of the storage box cannot be completely sterilized. On the other hand, the storage box made of a high polymer material will change in performance due to an increase in the number of sterilizations. Therefore, the storage box in the prior art is designed as a disposable product. This "use and discard" storage box also increases the cost of surgical consumables and causes waste of medical resources.

[0061] To solve the above technical problems, the embodiment one of the present application provides a storage box of an anchor nail, which is a folding storage box designed in a "paper folding structure". The technical essence lies in that a specific crease design of a flat sheet metal material is used to fold the planar material into a three-dimensional cubic cavity structure, and the anchor nail can be reversibly unfolded into a T-shaped plane after implantation. This design breaks through the limitations of the fixed form of the traditional anchor nail storage box and realizes dynamic reversible conversion from a plane to a three-dimensional structure.

[0062] The embodiment two of the present application provides a separate implantation system of an anchor nail, which comprises an inserter and the storage box of the anchor nail provided in the embodiment one. The anchor nail, the storage box and the inserter are separately arranged, so that only the anchor nail is a disposable product, the storage box and the inserter can be reused, and the anchor nail, the storage box and the inserter can be quickly separated and assembled. This breaks through the limitation of the overall consumable of the traditional anchor nail implantation system, not only reduces the cost of surgical consumables and reduces resource waste, but also significantly reduces the storage and logistics costs.

[0063] Embodiment one:

[0064] As Figures 1-4 , Figure 8 and Figure 9As shown, this embodiment provides a storage box for anchor nails. The storage box 100 has a flat state and a three-dimensional state, and can be converted between the flat state and the three-dimensional state. The storage box 100 includes an outer shell 1, a bottom cover 2, a top cover 3, and an internal folding layer 4. The outer shell 1 is enclosed by four sequentially connected side panels. The bottom cover 2 and the top cover 3 are respectively connected to the ends of the first side panel 11 of the outer shell 1. The bottom cover 2 is provided with an inlet for inserting an inserter 200, and the top cover 3 is provided with an outlet for the anchor nail 300 and the inserter 200 to pass through. The internal folding layer 4 is connected to the second side panel 12 of the outer shell 1. Crease lines 5 are provided between the side panels of the outer shell 1, between the bottom cover 2 and the first side panel 11, between the top cover 3 and the first side panel 11, between the internal folding layer 4 and the second side panel 12, and on the internal folding layer 4; in the flat state, the storage box 100 is unfolded into a plane; in the three-dimensional state, the outer shell 1, the bottom cover 2 and the top cover 3 are folded along the crease lines 5 to form a box body, and at the same time, the internal folding layer 4 is folded into the box body to form an anchor storage cavity 62.

[0065] Specifically, when laid flat, the four side panels are the first side panel 11, the third side panel 13, the fourth side panel 14, and the second side panel 12, which are connected in sequence along a first direction. That is, the inner folding layer 4 is connected to the second side panel 12 and extends along the first direction. The bottom cover 2 and the top cover 3 are respectively provided at both ends of the first side panel 11 along the second direction. The first and second directions are perpendicular, so that the storage box 100 is flattened into a T-shaped plane. The design of the one-way connection between the inner folding layer 4 and the outer shell 1 ensures the integrity of the storage box 100 and reduces the complexity of operation.

[0066] Of course, in other embodiments, the inner folding layer 4 may also be connected to the first side panel 11 in one direction.

[0067] In one embodiment, both ends of the third side panel 13 along the second direction are provided with a first flange 15, and both ends of the second side panel 12 along the second direction are provided with a second flange 16. During the process of folding the outer shell 1, bottom cover 2, and top cover 3 along the crease line 5 to form the box body, the two first flanges 15 are folded to the same side of the bottom cover 2 and top cover 3, and the two second flanges 16 are folded to the other side of the bottom cover 2 and top cover 3. One pair of oppositely disposed first flanges 15 and second flanges 16 are supported on the inner side of the bottom cover 2, and the other pair of oppositely disposed first flanges 15 and second flanges 16 are supported on the inner side of the top cover 3. The end of the bottom cover 2 away from the first side panel 11 is folded into a third flange 22, which is inserted into the box body; the end of the top cover 3 away from the first side panel 11 is folded into a fourth flange 32, which is inserted into the box body, thereby forming a closed and stable box body.

[0068] The crease line 5 comprises a third crease line 53, which is arranged between the side plates, between the side plates and the bottom cover 2, the top cover 3, the first flange 15 and the second flange 16, between the bottom cover 2 and the third flange 22, and between the top cover 3 and the fourth flange 32. When folded into a three-dimensional state, the inner folding layer 4 is folded first, and then the shell 1, the bottom cover 2 and the top cover 3 are folded into a box body along the third crease line 53.

[0069] During storage and transportation, the storage box 100 remains in a flat state and is packaged separately from the anchor 300. Compared with the overall packaging of the existing disposable anchor implant kit, the volume is large, and the packaging, transportation and storage space is wasted due to the weak connection between the anchor 300 and the inserter 200. The storage space and transportation cost are saved. Before the operation, the crease line 5 is quickly folded into a three-dimensional state, and after the operation, it is flattened for high-temperature and high-pressure sterilization, completely eliminating the gaps and dead angles that are easy to cause incomplete sterilization. Compared with the existing disposable storage box, the cost of consumables for a single operation can be effectively reduced, and medical waste can be reduced.

[0070] In an embodiment, the storage box 100 is made of a metal material with elasticity and durability, and the surface is coated with a corrosion-resistant coating. Illustratively, the storage box 100 is made of an ultra-thin titanium alloy metal sheet processed by a precise creasing process, and the reversible conversion between the flat state and the three-dimensional state is realized by folding and unfolding the preset crease line 5. Titanium alloy combines elasticity and durability, so that it can maintain structural integrity in multiple folding or unfolding cycles. The corrosion-resistant coating on the surface can meet the requirements of multiple antibacterial treatments, further reducing the risk of biological contamination in repeated use.

[0071] In an embodiment, the inner folding layer 4 comprises four support plates connected in sequence, and first crease lines 51 are arranged between the support plates and the second side plate 12 and between adjacent support plates. A second crease line 52 is arranged in the middle of each support plate, and a surrounding plate is formed between the two second crease lines 52. The four support plates are sequentially folded along the first crease lines 51 and the second crease lines 52, and each support plate corresponds to a side plate to form a three-prism-shaped cavity 61. The four surrounding plates form an anchor storage cavity 62. The inner folding layer 4 is folded in the box body to form four three-prism-shaped cavities 61, which are evenly distributed around the anchor storage cavity 62 to form a rigid support frame. The anchor storage cavity 62 is located at the geometric center of the rigid support frame, and its structural stability directly benefits from the stable support of the surrounding three-prism-shaped cavities 61. When the anchor 300 in the anchor storage cavity 62 is subjected to axial pressure of the inserter 200, the pressure is transmitted to the surrounding plate of the anchor storage cavity 62 through the anchor 300, and the surrounding plate further disperses and conducts the force to the support structure of the firm three-prism-shaped cavity 61, effectively resisting compression deformation. The impact force, torque or bending moment generated during the impact implantation or screw implantation is absorbed and offset by the surrounding three-prism-shaped cavities 61, preventing the anchor storage cavity 62 from tilting, twisting or collapsing, and ensuring the overall stability of the structure during implantation.

[0072] In an embodiment, the surrounding plate comprises a first surrounding plate 45 and a second surrounding plate 46 arranged opposite to each other. The first surrounding plate 45 and the second surrounding plate 46 are bent inward at one end close to the top cover 3 to form a limiting portion 63 into the anchor storage cavity 62. The limiting portion 63 is used to limit the movement of the anchor 300 in the anchor storage cavity 62. The limiting portion 63 can be flattened and coplanar with the surrounding plate under the extrusion of the anchor 300 when the anchor 300 is pushed out. The limiting portion 63 at the end of the first surrounding plate 45 and the second surrounding plate 46 bent inward constitutes a physical barrier, which uses the positive pressure generated by the elastic deformation of the material to lock the anchor 300 in the anchor storage cavity 62, and can resist the axial displacement of the anchor 300 due to inertia. When the inserter 200 applies an axial pushing force, the anchor 300 extrudes the limiting portion 63 to make it elastically flatten and coplanar with the surrounding plate, avoiding the push-out resistance caused by the traditional rigid buckle.

[0073] In an embodiment, as shown in Figure 1 , Figure 5 and Figure 6As shown, the first and second surrounding plates 45 and 46 are oppositely provided with limiting holes 66. When the anchor 300 is stored in the anchor storage cavity 62, the two oppositely arranged limiting holes 66 cooperate with the limiting structure on the anchor 300, which can be a limiting column or the like, and after the limiting structure is clamped into the limiting hole 66, the circumferential freedom of the anchor 300 is locked to prevent accidental deflection before implantation. It should be noted that the limiting structure and the limiting hole 66 are in clearance fit, and when the inserter 200 exerts axial pressure on the anchor 300, the limiting structure can slide out of the limiting hole 66 without damaging the limiting hole 66, and does not affect the reuse of the storage box 100.

[0074] The limiting portion 63 and the limiting hole 66 cooperate to axially constrain and circumferentially lock the anchor 300 in the storage state, ensuring that the position of the anchor 300 in the anchor storage cavity 62 does not shift, and further ensuring that the inserter 200 can accurately dock with the anchor 300.

[0075] In the prior art, the suture 400 is stored in a long-term tight state by cooperating with the winding wheel and the tensioning structure, which causes irreversible creep relaxation of the suture 400, directly affecting the postoperative tissue fixation.

[0076] In order to solve the above technical problems, as shown in Figures 1-3 and Figure 7 In an embodiment, the surrounding plate includes oppositely arranged third and fourth surrounding plates 47 and 48, and the third and fourth surrounding plates 47 and 48 are oppositely provided with cutting portions 64. The cutting portions 64 are formed between the two sides of the cutting portions 64 and the surrounding plate to form a gap for clamping the suture 400, and the end of the cutting portion 64 and the surrounding plate form an opening 65 for the suture 400 to pass out of the anchor storage cavity 62. For the anchor 300 with a suture, the suture 400 passes out of the tail end of the anchor 300, extends along the cavity wall of the anchor storage cavity 62 to the opening 65, and then extends into the three-prism-shaped cavity 61, and then is clamped in the gap between the side wall of the cutting portion 64 and the surrounding plate, which can fix the suture 400. When the anchor 300 is pushed out, the suture 400 is subjected to the friction force of the side wall of the cutting portion 64 and the surrounding plate, and maintains a certain tension. The fixing structure of the suture 400 completely eliminates the mechanical loss of the suture 400 during storage.

[0077] When the inner folding layer 4 in the flat state is folded into a three-dimensional state, the fourth support plate 44 is first folded inward along the two second crease lines 52 forming the fourth surrounding plate 48, then folded outward along the first crease line 51 between the fourth support plate 44 and the third support plate 43, then the third support plate 43 is folded inward along the two second crease lines 52 forming the second surrounding plate 46, then folded outward along the first crease line 51 between the third support plate 43 and the second support plate 42, then the second support plate 42 is folded inward along the two second crease lines 52 forming the third surrounding plate 47, then folded outward along the first crease line 51 between the second support plate 42 and the first support plate 41, then the first support plate 41 is folded inward along the two second crease lines 52 forming the first surrounding plate 45, and finally folded outward along the first crease line 51 between the first support plate 41 and the second side plate 12, that is, the inner folding layer 4 is folded into a three-dimensional state.

[0078] In an embodiment, as shown in Figure 1 、 Figure 4 and Figure 9 , the side plate is provided with a suture outlet 17. The suture 400 passes out of the opening 65 into the three-prism-shaped cavity 61 and then passes out of the suture outlet 17, without the need for fixation at the end. The suture 400 is guided by the cavity wall of the anchor storage cavity 62 and the tension management of the cutting part 64, avoiding material performance degradation due to long-term stress during storage, and ensuring the stability of postoperative tissue fixation.

[0079] The provision of the suture outlet 17 also reduces the weight of the storage box 100, meeting the lightweight design of the storage box 100.

[0080] In an embodiment, communication grooves 49 are provided between the support plates. The provision of the communication grooves 49 ensures the stability of the support while facilitating the bending and folding of the support plates.

[0081] In an embodiment, the inlet is a guide hole 21 with a guide groove 211 on opposite sides. The guide groove 211 cooperates with the guide structure on the insertion rod 202 of the inserter 200, and is used to guide the inserter 200 to accurately dock with the anchor storage cavity 62 and the anchor 300.

[0082] In an embodiment, the outlet is a cross-shaped aperture 31. The provision of the cross-shaped aperture 31 facilitates the pushing of the anchor 300 out of the storage box 100 by the inserter 200, allowing the guide structure on the insertion rod 202 to pass through, while also having a radial constraint effect on the insertion rod 202.

[0083] The storage box 100 provided by the embodiment is processed by a precise creasing process of an ultrathin metal sheet, and the material of the storage box 100 has elasticity and durability. The storage box 100 in a flat state is folded into a box body with an anchor storage cavity 62, so that the anchor 300 and the suture 400 can be stored in the anchor storage cavity 62. The suture 400 extends along the cavity wall of the anchor storage cavity 62 to the opening 65 into the three-prism cavity 61, and then is clamped in the gap between the side wall of the cutting part 64 and the surrounding plate, and then is pulled out of the box body through the suture outlet 17. The suture 400 is fixed by the extrusion force of the side wall of the cutting part 64 and the surrounding plate, so that the anchor 300 is pushed out, and the suture 400 maintains a certain tension. The end of the suture 400 does not need to be fixed, and the mechanical trigger of the inserter 200 realizes the free release of the suture 400. When the anchor 300 is implanted, the storage box 100 can be completely unfolded into a planar form along the crease line 5, and all the internal structures are exposed as open surfaces, which facilitates thorough cleaning and high-temperature and high-pressure sterilization. The unfolded planar structure eliminates the gaps and dead angles of the traditional three-dimensional container, ensures the efficient penetration of the sterilization medium, and meets the hygiene standards of the repeated use of medical devices.

[0085] As shown in Figures 8-16 The embodiment provides a detachable implantation system of an anchor, which comprises an inserter 200 and the storage box of the anchor provided by the embodiment one. The inserter 200 comprises a handle 201 and an insertion rod 202. The insertion rod 202 can be inserted into the anchor storage cavity 62 and is inserted and fixed with the anchor 300. The storage box 100 can be moved to the handle 201 and is fixed to the inserter 200. The insertion rod 202 of the inserter 200 is inserted into the anchor storage cavity 62 and is inserted and fixed with the anchor 300. The anchor 300 is pushed out of the box body, the suture 400 is automatically released, the storage box 100 is moved to the handle 201 and is fixed to the inserter 200, so that the anchor 300 can be implanted. When the implantation is completed, the storage box 100 is detached from the inserter 200, and then the storage box 100 can be unfolded into a flat state along the crease line 5, and is subjected to high-temperature and high-pressure sterilization treatment, so as to be repeatedly used.

[0086] In an embodiment, the insertion rod 202 is provided with a plug-in head 203 at one end away from the handle 201, and the plug-in head 203 is plug-in fixed with the anchor 300; the plug-in head 203 is provided with a guide boss 2031 for guiding the insertion direction. When the inserter 200 is docked with the storage box 100, the guide boss 2031 is first aligned with the guide groove 211 on the guide hole 21, and then the insertion rod 202 is inserted into the anchor storage cavity 62 to be accurately docked with the anchor 300, so that the plug-in head 203 is plug-in fixed with the anchor 300, and then the anchor 300 is pushed out of the storage box 100; when the guide boss 2031 passes through the top cover 3, the cross aperture 31 on the top cover 3 allows the guide boss 2031 to pass through, and at the same time has a radial constraint effect on the insertion rod 202.

[0087] In an embodiment, the insertion rod 202 is provided with a clamping boss 204 at one end close to the handle 201; when the storage box 100 is moved to the handle 201, the clamping boss 204 passes through the inlet, and the storage box 100 is clamped and fixed between the clamping boss 204 and the handle 201 by twisting. The inlet is a guide hole 21 provided with a guide groove 211 on opposite sides, and the structure of the clamping boss 204 is matched with that of the guide hole 21, so that when the storage box 100 is moved to the handle 201, the clamping boss 204 can pass through the inlet, and then the storage box 100 is twisted counterclockwise by 90 degrees, so that the bottom cover 2 of the storage box 100 is clamped between the clamping boss 204 and the handle 201, achieving clamping and fixing of the storage box 100 and the inserter 200. After implantation is completed, the storage box 100 is twisted clockwise by 90 degrees, so that the inlet on the bottom cover 2 can move away from the handle 201 through the clamping boss 204, and then the storage box 100 is removed from the insertion rod 202.

[0088] The anchor separation type implantation system provided in the embodiment includes the inserter 200 and the above-mentioned anchor storage box 100, the storage box 100 is folded to form a three-dimensional state having the anchor storage cavity 62, for storing the anchor 300 and realizing assembly of the anchor 300 and the inserter 200; the inserter 200 assembled with the anchor 300 realizes implantation of the anchor 300; after implantation is completed, the storage box 100 is unfolded to a flat state and can be reused after high-temperature high-pressure sterilization, and the inserter 200 can also be reused. By separating the anchor 300 and the inserter 200, the storage box 100 and the inserter 200 can be reused, effectively reducing the consumable cost of a single operation, and reducing medical waste. At the same time, compared with the large packaging volume of the disposable anchor implantation kit in the prior art, the weak connection between the anchor 300 and the inserter 200 causes waste of packaging, transportation and storage space. The anchor separation type implantation system can independently package the anchor 300, the storage box 100 and the inserter 200, which can significantly reduce the warehousing and logistics cost.

[0089] The anchor separation implant system provided by the embodiment is applied to a rotator cuff repair surgery. Before the surgery, a suture anchor 300 of a suitable size, a corresponding storage box 100 and an inserter 200 are prepared. The suture anchor 300 is loaded into the storage box 100 in a flat state, the suture 400 extends from the opening 65 and is clamped between the side wall of the cutting part 64 and the surrounding plate, then the storage box 100 is folded along the crease line 5 to a three-dimensional state. Then the guide boss 2031 of the insertion connector 203 of the inserter 200 is aligned with the guide groove 211 in the guide hole 21 of the bottom cover 2, the insertion rod 202 is inserted into the anchor storage cavity 62, the insertion connector 203 is inserted and fixed with the anchor 300, the force on the insertion rod 202 is continuously applied, the anchor 300 is pushed out and the suture 400 is released synchronously, until the storage box 100 reaches the handle 201, at this time the suture 400 is located between the cutting part 64 and the insertion rod 202, the suture 400 is temporarily fixed by the friction force of the cutting part 64 and the surrounding plate, and is kept in a low tension state. After the guide hole 21 on the bottom cover 2 passes through the clamping block 204, the storage box 100 is rotated counterclockwise by 90°, and the storage box 100 can be clamped between the clamping block 204 and the handle 201. At this time, the anchor 300 can be implanted by knocking the handle 201 or rotating the handle 201. When the implantation surgery is completed, the inserter 200 is moved in the direction opposite to the implantation direction, so that the suture 400 is completely released. The storage box 100 is rotated clockwise again, and is rotated by 90° again, so that the storage box 100 is removed from the insertion rod 202. The removed storage box 100 is unfolded along the crease line 5 to a flat state, after the residual tissue is removed, the storage box 100 is subjected to high-temperature and high-pressure sterilization together with the inserter 200, and the next surgery cycle can be started.

[0090] The above merely provides the preferred embodiment of the present application, and for those skilled in the art, the specific implementation manner and application scope can be changed according to the idea of the present application, and the content of the description should not be understood as a limitation of the present application.
