[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0029] Reference Figure 1 This disclosure provides a structural diagram of an anchor implanter, which may include a suture anchor 1 and a drive structure 2 for driving the suture anchor 1 into a predetermined bone position.

[0030] Reference Figure 2 and Figure 3 The suture anchor 1 includes a trabecular porous structure. The head of the suture anchor 1 is equipped with an anchor blade, and the tail is equipped with a drive mounting part 11. The anchor blade of the suture anchor 1 can be inserted into and fixed into the bone tissue of the affected area for treatment. Because the suture anchor 1 includes a trabecular porous structure, after the suture anchor 1 is inserted into the affected area, it facilitates tissue ingrowth into the pores of the trabecular porous structure, enabling reliable connection with the suture anchor 1. This accelerates early healing of the affected area and improves the reliability of the anchor implanter.

[0031] As an example, the porosity of the trabecular porous structure is 50%-70%, and the pore size range is 300μm-700μm. This facilitates the ingrowth of human bone, allowing the suture anchor 1 to better integrate with the affected area, thereby accelerating early healing. As an example, the porosity of the trabecular porous structure can be 55%, 60%, or 65%, but is not limited to these values. Furthermore, the pore size range of the trabecular porous structure is 350μm, 400μm, 450μm, 500μm, 550μm, 600μm, or 650μm, but is not limited to these values.

[0032] In this embodiment, a trabecular porous structure is arranged on the outer periphery of the suture anchor 1 to facilitate the ingrowth of bone tissue or other tissues from the affected area into the gaps of the trabecular porous structure, thereby promoting early healing of the affected area. The entire suture anchor 1 may be composed of a trabecular porous structure, but is not limited thereto. Furthermore, to improve the structural strength of the suture anchor 1, it may also include a nail body formed by a solid structure, with the trabecular porous structure wrapping around the outer periphery of this nail body and extending from the outer periphery towards the center, but is not limited thereto.

[0033] Referring again to the accompanying drawings, the drive structure 2 can drive the suture anchor 1 to be inserted into the bone tissue of the affected area. For example, but not limited to, the head of the drive structure 2 can be inserted into the drive mounting part 11 of the suture anchor 1 to drive the suture anchor 1 to be inserted into the affected area.

[0034] In this embodiment, the driving structure 2 can be driven into the affected area manually by the operator, or the anchor 1 can be driven into the affected area by an electric component such as a motor, both of which are within the protection scope of this disclosure.

[0035] Furthermore, the outer periphery of the anchor pin 1 is provided with threads, for example, but not limited to, the threads extending continuously from the head to the tail of the anchor pin 1, that is, the outer periphery of the anchor pin 1 is provided with full threads.

[0036] When using the anchor implanter to treat a patient, the suture anchor 1 can be connected to the head of the drive structure 2. By pressing forward and twisting the drive structure 2, the suture anchor 1 can be rotated to be inserted into the bone tissue of the affected area.

[0037] As an example, the thread of the wire anchor 1 is set to a self-tapping thread, which simplifies the installation operation of the wire anchor 1, but is not limited thereto. In an alternative embodiment, the head of the wire anchor 1 is configured such that its cross-sectional area gradually decreases from the tail to the head to form a cone, but is not limited thereto.

[0038] To facilitate the connection of the wire 3 to the anchor pin 1, in this embodiment, the anchor pin 1 has two circumferential threading holes 12. The circumferential threading holes 12 penetrate through opposite sides of the anchor pin 1, and the two circumferential threading holes 12 are spaced apart along the extension direction of the anchor pin 1. The two ends of the wire 3 pass through the two circumferential threading holes 12 respectively and extend towards the tail of the anchor pin 1.

[0039] To prevent the suture attached to the suture anchor 1 from being worn and broken during bone insertion, in this embodiment, the suture anchor 1 further includes a recessed groove 13 formed from its outer peripheral wall inward. Two circumferential suture holes 12 are respectively disposed in the recessed groove 13. With this arrangement, the suture 3 can be placed in the recessed groove 13, and the suture 3 will not be broken due to bone wear and compression during bone insertion, thereby further improving the reliability of the anchor implanter, but not limited thereto.

[0040] In an optional embodiment, the depth of the settling tank 13 is not less than the diameter of the line 3, but is not limited thereto.

[0041] Furthermore, to prevent scratching of the patient's bone or other tissues at the connection between the groove 13 and the outer peripheral wall of the suture anchor 1 during bone insertion, a rounded corner can be provided at the connection between the groove 13 and the outer peripheral wall of the suture anchor 1. When the affected tissue comes into contact with the rounded corner, scratching is avoided, thus improving the safety of the anchor implanter.

[0042] To further enhance the safety of the suture 3 attached to the suture anchor 1 and prevent it from breaking due to wear and compression, the suture anchor 1 is also provided with a central suture hole extending along its extension direction. The central suture hole extends from the tail end of the suture anchor 1 towards the head. Two circumferential suture holes 12 are connected to the central suture hole. After passing through the two circumferential suture holes 12, the suture can extend into the central suture hole and then extend towards the tail end of the suture anchor 1. Because the suture 3 is concealed within the central suture hole, it will not be worn or compressed during the insertion of the suture anchor 1 into the bone, thus improving the safety of the suture 3 and consequently the safety of the anchor implanter.

[0043] return Figure 3 The tail end of the central threading hole is non-circular to form a drive mounting part 11. The drive structure 2 includes a drive rod 21 and a drive handle 22. The head of the drive rod 21 can be detachably inserted into the drive mounting part 11, and the drive handle 22 is connected to the tail end of the drive rod 21. When the drive handle 22 is turned, the suture anchor 1 can be rotated, thereby allowing it to be inserted into the patient's affected area.

[0044] This disclosure achieves a reliable connection between the drive structure 2 and the suture anchor 1 by detachably connecting the head of the drive rod 21 of the drive structure 2 to the drive mounting part 11. For example, but not limited to, the head of the drive rod 21 can be inserted into the drive mounting part 11, which has a non-circular hole. This arrangement prevents relative rotation between the drive rod 21 and the suture anchor 1. When the operator drives the drive handle 22 to rotate, the suture anchor 1 can be screwed and inserted into the bone tissue of the affected area. In this embodiment, the drive handle 22 of the drive structure 2 is easy for the operator to grip, which improves the ease of use of the anchor implanter to a certain extent.

[0045] In this embodiment, the drive mounting portion 11 may have a regular polygonal hole, a plum blossom-shaped hole, a star-shaped hole, or an elliptical hole, all of which are within the protection scope of this disclosure. For ease of description, this embodiment uses a regular hexagonal hole as an example for the drive mounting portion 11, but this is not a limitation. In optional embodiments, the central wire-passing hole may have the same shape as the drive mounting portion 11, or the head of the central wire-passing hole may be a circular hole, and the drive mounting portion 11 may have a regular hexagonal hole, all of which are within the protection scope of this disclosure.

[0046] Reference Figure 1 , Figure 4 as well as Figure 5 To facilitate the smooth passage of the wire connected to the anchor pin 1 from the tail end of the drive structure 2, the drive rod 21 is provided with a side slot hole 211. The side slot hole 211 is arranged on one circumferential side of the drive rod 21 and passes through the head and tail ends of the drive rod 21. The side slot hole 211 is connected to the central wire hole. The drive handle 22 is provided with a through hole that passes through the head and tail ends of the drive handle 22. The wire 3 can pass through the central wire hole of the anchor pin 1 and the side slot hole 211 of the drive rod 21 in sequence, and finally pass out from the tail end of the drive structure 2.

[0047] To prevent the drive handle 22 and the drive rod 21 from rotating relative to each other, in this embodiment the drive handle 22 and the drive rod 21 are fixedly connected. For example, but not limited to, the drive handle 22 and the drive rod 21 are metal parts, and the drive handle 22 and the drive rod 21 can be connected together by welding or by adhesive bonding.

[0048] To avoid secondary injury to the patient upon removal of the suture anchor 1 after the affected area has healed, in this embodiment, the suture anchor 1 is a bioabsorbable metal component. This bioabsorbable metal component provides sufficient strength after the suture anchor 1 is inserted into the bone, enabling a reliable connection with the bone. After the affected area heals, the bioabsorbable metal component will be absorbed by the body and disappear, thus eliminating the need for surgical removal of the suture anchor 1. Alternatively, the suture anchor 1 may be made of zinc alloy or magnesium alloy, but is not limited to these materials.

[0049] In the above embodiments, the suture anchor 1 with a screw-insertion method is used as an example for explanation. Accordingly, the driving structure 2 can drive the suture anchor 1 to rotate, thereby driving the suture anchor 1 to be implanted at the predetermined bone position, but it is not limited thereto. As needed, the suture anchor 1 can also be a drive-in suture anchor, and the corresponding driving structure 2 can place it into the predetermined bone position by impacting the tail of the suture anchor 1.

[0050] The anchor implanter disclosed herein includes a bone-like trabecular structure. After the suture anchor 1 is implanted into the affected area, tissue that is conducive to the ingrowth of the affected area is introduced into the gap of the bone-like trabecular structure, thereby making the tissue of the affected area firmly bonded to the suture anchor 1, which is conducive to the early healing of the affected area tissue and thus improves the reliability of the anchor implanter.
