[0001] The utility model relates to the field of medical instruments, in particular to a wire anchor and a wire anchor kit. Background Art

[0002] Wire anchors are commonly used in surgery and can be used anywhere soft tissue needs to be reconnected to bone.

[0003] Currently, in surgical procedures using wire anchors, a bone hole is usually drilled in the bone first, then the bone hole is tapped, and then the wire anchor is screwed into the bone hole using an inserter. The soft tissue is then tied to the wire anchor using sutures on the wire anchor to achieve fixation between the soft tissue and the bone.

[0004] However, in the process of screwing the wire anchor into the bone hole, stress is inevitably generated on the bone hole, which expands the diameter of the bone hole, thereby reducing the fixing strength of the wire anchor and causing problems such as loosening and dislodging of the wire anchor.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1 and Figure 2 As shown, the utility model discloses a wire anchor, which is used in surgical operations. The wire anchor includes an expansion portion 1b, a nail head portion 1a connected to a first end of the expansion portion 1b, and a nail tail portion 1c connected to a second end of the expansion portion 1b. The nail head portion 1a, the expansion portion 1b, and the nail tail portion 1c are all made of metal materials, and the nail head portion 1a, the expansion portion 1b, and the nail tail portion 1c are integrally formed. The wire anchor is provided with a through hole, which sequentially passes through the nail head portion 1a, the expansion portion 1b, and the nail tail portion 1c. The nail head portion 1a, the expansion portion 1b, and the nail tail portion 1c are coaxially arranged, and the axis of the nail head portion 1a, the axis of the expansion portion 1b, and the axis of the nail tail portion 1c are all coaxially arranged with the axis of the through hole. The nail head portion 1a is provided with a suture fixing portion, and a suture is fixed to the suture fixing portion. A first connection portion is provided on the nail head portion 1a, and a second connection portion is provided on the nail tail portion 1c. The wire anchor is used in conjunction with an inserter, that is, the first connection portion and the second connection portion can cooperate with the inserter. The structure of the inserter can be various. In this embodiment, the inserter includes a first operating rod 2a and a second operating rod 2b. The first operating rod 2a is provided with a third connection portion that cooperates with the first connection portion, and the second operating rod 2b is provided with a fourth connection portion that cooperates with the second connection portion. In other embodiments, the inserter may also include a fixed block, the fixed block is provided with the fourth connection portion that cooperates with the second connection portion, the fixed block is provided with a telescopic rod, and the telescopic rod is provided with the third connection portion that cooperates with the first connection portion. In this embodiment, the steps for using the wire anchor of the utility model are as follows:

[0032] Step 1: Drill a hole in the bone;

[0033] Step 2: mate the first connection part and the second connection part with the inserter. Specifically, the first connection part mates with the third connection part, and the second connection part mates with the fourth connection part.

[0034] Step 3: driving the inserter to drive the wire anchor into the bone hole;

[0035] Step 4: driving the inserter to move the nail head portion 1a toward the nail tail portion 1c while the nail tail portion 1c remains stationary, causing the expansion portion 1b to expand and deform. The cross-sectional area of ​​the expansion portion 1b is larger than the radial cross-sectional area of ​​the bone hole, and the expansion portion 1b is stuck in the bone hole.

[0036] Step 5: Separate the first connecting portion and the second connecting portion from the inserter, that is, separate the wire anchor from the inserter; although after the wire anchor is separated from the inserter, the squeezing force of the nail head 1a and the nail tail 1c on the expansion portion 1b disappears, and the expansion portion 1b rebounds; however, since the expansion portion 1b is made of metal, once the expansion portion 1b is deformed by external force, even if the external force is removed, the expansion portion 1b can maintain the deformed state and rebound slightly, so the expansion portion 1b can still be stuck in the bone hole;

[0037] Step 6: Use sutures to secure the soft tissue.

[0038] The wire anchor of the present invention is provided with the expansion portion 1b so that when the nail head portion 1a is driven to move toward the nail tail portion 1c, the expansion portion 1b expands and deforms, and the wire anchor can be stuck in the bone hole and is not easy to fall out. In addition, the wire anchor of the present invention has a simple structure and is easy to process and manufacture.

[0039] like Figures 3 to 6As shown, in this embodiment, a first through-hole is defined as the through-hole located within the nail head portion 1a. The first connecting portion is located on the inner wall of the first through-hole and is an internal thread 1d that mates with the inserter. Accordingly, the inserter is provided with a first external thread 2c that mates with the internal thread 1d. Specifically, the first external thread 2c that mates with the internal thread 1d is provided on the first operating rod 2a of the inserter. As mentioned above, the first connecting portion can mate with the inserter, that is, after the first operating rod 2a enters the first through-hole, the internal thread 1d mates with the first external thread 2c. By rotating the first operating rod 2a, while maintaining rotation only about its own axis, the screw drive component is used to drive the nail head 1a toward the direction away from the bone hole. Therefore, rotating the first operating rod 2a can drive the nail head 1a toward the nail tail 1c. At the same time, because the second connecting portion cooperates with the fourth connecting portion to restrict the movement of the nail tail portion 1c away from the bone hole, the nail tail portion 1c is kept stationary. Therefore, as the nail head portion 1a moves, the expansion portion 1b expands toward the inside of the bone hole until it is stuck on the inner wall of the bone hole. The provision of the internal thread 1d in this utility model simplifies the operation steps of the inserter. In other embodiments, the first connecting portion may also be provided with a card slot on the inner wall of the first through hole, and a retractable card block may be provided on the first operating rod 2a. When the first operating rod 2a is inserted into the first through hole, the card block is inserted into and cooperates with the card slot, that is, the first connecting portion cooperates with the third connecting portion to pull the first operating rod 2a with the card block away from the bone hole, and the nail head 1a moves in the direction away from the bone hole. Similarly, because the second connecting portion cooperates with the fourth connecting portion, the nail tail 1c is restricted from moving in the direction away from the bone hole, that is, the nail tail 1c is restricted from being fixed, and the expansion portion 1b expands toward the inside of the bone hole.

[0040] like Figure 1 、 Figure 2 and Figure 6 As shown, in this embodiment, the second connecting portion is arranged at the end of the nail tail 1c away from the expansion portion 1b, and the second connecting portion is a straight groove 1e that cooperates with the fourth connecting portion. Therefore, the fourth connecting portion is a protrusion 2d that cooperates with the straight groove 1e, and the protrusion 2d and the first external thread 2c are not arranged on the same axis. When the protrusion 2d cooperates with the straight groove 1e, the inserter can be driven to drive the wire anchor into the bone hole. The utility model facilitates the cooperation between the inserter and the wire anchor through the provision of the straight groove 1e. In other embodiments, the second connecting portion can also be other shapes such as the first step surface.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the outer surface of the nail head 1a, the outer surface of the expansion portion 1b, and the outer surface of the nail tail 1c are all provided with a second external thread 1f, and each of the second external threads 1f is interconnected to form a whole, that is, the outer surface of the wire anchor is provided with threads. Therefore, in the process of opening a bone hole, it is also necessary to tap the entire inner wall of the bone hole. In the process of operating the inserter to insert the wire anchor into the bone hole, the inserter is used to screw the wire anchor into the bone hole. Because the wire anchor is ultimately fixed in the bone hole mainly through the expansion of the expansion portion 1b, the diameter of the bone hole can be slightly larger than the diameter of the wire anchor, preventing the wire anchor from wearing the inner wall of the bone hole during the process of screwing the bone hole into the bone hole, thereby increasing the diameter of the bone hole. During surgery, the entire bone hole is typically tapped. To facilitate entry of the nail head 1a into the bone hole, the diameter of the nail head 1a is smaller than the diameter of the unexpanded expansion portion 1b. As the nail head 1a moves toward the nail tail 1c, the second external thread 1f on the nail head 1a can scrape the threads on the inner wall of the bone hole. The present invention facilitates entry of the wire anchor into the bone hole by providing the second external thread 1f on the outer surface of the wire anchor. Furthermore, when the expansion portion 1b expands, the second external thread 1f on the outer surface of the expansion portion 1b enables the wire anchor to better adhere to the inner wall of the bone hole. In other embodiments, the nail head portion 1a, the nail tail portion 1c, and the unexpanded expansion portion 1b are all cylindrically shaped. When tapping a bone hole, threads are tapped on the portion of the bone hole inner wall near the bone hole opening. When the nail head portion 1a moves toward the nail tail portion 1c, the bone hole inner wall corresponding to the movement path of the nail head portion 1a is free of threads. This prevents the second external threads 1f on the nail head portion 1a from scratching the threads on the bone hole inner wall. However, such bone holes are more difficult to tap. In other embodiments, the second external threads 1f may be provided only on the outer surfaces of the expansion portion 1b and the nail tail portion 1c. Although screwing the wire anchor into the bone hole is more complicated than in this embodiment, the movement of the nail head portion 1a toward the nail tail portion 1c does not damage the threads on the bone hole inner wall.

[0042] like Figure 3 and Figure 4As shown, the inner wall of the through hole located in the expansion portion 1b is in the shape of an arc surface, and the through hole located in the expansion portion 1b is defined as a second through hole. The radial cross-sectional area of ​​the middle portion of the second through hole is larger than the radial cross-sectional area of ​​the ends of the second through hole, that is, the arc surface opening of the second through hole is arranged toward the axis of the second through hole. By limiting the shape of the inner wall of the expansion portion 1b, the present invention allows the expansion portion 1b to expand toward the inner wall of the bone hole during expansion, and will not contract toward the axis of the second through hole. In other embodiments, a plurality of V-shaped grooves may also be provided on the inner wall of the second through hole, which can also allow the expansion portion 1b to expand toward the inner wall of the bone hole during expansion.

[0043] like Figure 1 and Figure 2 As shown in FIG. 1 , in this embodiment, the outer wall of the expansion portion 1b is provided with a plurality of slots communicating with the through holes located in the expansion portion 1b. Figure 1 As shown, when the expansion part 1b is not expanded, each of the slits is linear and arranged around the axis of the expansion part 1b. And when the expansion part 1b is in an unexpanded state, each of the slits is arranged parallel to the axis of the expansion part 1b. The utility model facilitates the expansion of the expansion part 1b through the arrangement of the slits, and also facilitates the bone to pass through the slits and grow into the second through hole, further making it difficult for the wire anchor to fall out of the bone hole. In other embodiments, a plurality of through holes connected to the through hole located in the expansion part 1b may also be provided on the outer wall of the expansion part 1b. A plurality of slits connected to the through hole located in the expansion part 1b may also be provided on the outer wall of the expansion part 1b, but each of the slits may cooperate with each other to form a spiral shape.

[0044] like Figures 1 to 4 As shown, in this embodiment, the suture fixing portion is a crossbar 1g, both ends of which are connected to the inner wall of the through hole. Specifically, the crossbar 1g passes through the axis of the first through hole, and both ends of the crossbar 1g are connected to the inner wall of the first through hole. The suture is fixed to the crossbar 1g, and the crossbar is arranged on the side of the internal thread 1d away from the nail tail 1c. The utility model facilitates the fixing of the suture to the crossbar 1g by setting the suture fixing portion as the crossbar 1g. In other embodiments, the suture fixing portion can also be a ring arranged on the inner wall of the first through hole, and the suture is fixed to the ring.

[0045] like Figures 1 to 8As shown, the present invention also discloses a wire anchor kit, which includes an inserter and the wire anchor described in this embodiment. In this embodiment, the inserter includes a first operating rod 2a and a second operating rod 2b. The first operating rod 2a is used to cooperate with the first connecting portion, and the second operating rod 2b is used to cooperate with the second connecting portion. The first operating rod 2a and the second operating rod 2b are movable relative to each other. According to the above, the first operating rod 2a is provided with the first external thread 2c that cooperates with the internal thread 1d, and the second operating rod 2b is provided with the protrusion 2d that cooperates with the slot 1e. The operator engages the internal thread 1d with the first external thread 2c and the slot 1e with the protrusion 2d, and then operates the second operating rod 2b to screw the wire anchor into the bone hole. The second operating rod 2b is then kept stationary and the first operating rod 2a is rotated so that the nail head 1a moves toward the nail tail 1c. The utility model makes the inserter structure simple and easy to operate by disposing the first operating rod 2a and the second operating rod 2b.

[0046] like Figures 5 to 8 As shown, in this embodiment, the first operating rod 2a and the second operating rod 2b are both tubular, the second operating rod 2b is sleeved on the outside of the first operating rod 2a, and the interior of the first operating rod 2a is used for the passage of the suture. The first end of the first operating rod 2a is provided with a third connecting portion for cooperating with the first connecting portion, that is, the third connecting portion is the first external thread 2c. The first end of the second operating rod 2b is provided with a fourth connecting portion for cooperating with the second connecting portion, that is, the fourth connecting portion is the protrusion 2d. The third connecting portion and the fourth connecting portion are both located on the same side of the second operating rod 2b, that is, the external thread 2c and the protrusion 2d are both located on the same side of the second operating rod 2b. By sleeved on the outside of the first operating rod 2a, the utility model makes the inserter structure compact. In other embodiments, the first operating rod 2a is tubular and the second operating rod 2b can be cylindrical. The first and second operating rods 2a and 2b are arranged adjacent to each other side by side. In this case, the second operating rod 2b is first used to insert the wire anchor into the bone hole, and then the first operating rod 2a is operated to drive the nail head 1a to move. In addition, in other embodiments, when the first connecting portion is the slot provided on the inner wall of the first through hole, the third connecting portion is the block that cooperates with the slot. When the second connecting portion is the first stepped surface, the fourth connecting portion can also be a second stepped surface that cooperates with the first stepped surface.

[0047] like Figures 5 to 8As shown, in this embodiment, a first handle 2e is provided at the second end of the first operating rod 2a, and a second handle 2f is provided at the second end of the second operating rod 2b. Both the first handle 2e and the second handle 2f are located on a side away from the fourth connecting portion, i.e., they are located on the same side and away from the protrusion 2d. The second handle 2f prevents the first handle 2e from moving toward the fourth connecting portion, i.e., the second handle 2f prevents the first handle 2e from moving toward the protrusion 2d. The provision of the first and second handles 2e and 2f prevents the first operating rod 2a from slipping out of the second operating rod 2b during screwing of the wire anchor into the bone hole. Furthermore, when the first handle 2e abuts the second handle 2f, the first operating rod 2a can be easily rotated about the first operating rod 2a. In other embodiments, when the first and second operating rods 2a and 2b are adjacent and side by side, and the first connecting portion is a slot and the third connecting portion is a retractable block, the first and second handles 2e and 2f may be omitted.

[0048] In summary, the wire anchor of the present invention, through the provision of the expansion portion 1b, enables the expansion portion 1b to expand and deform when the nail head portion 1a is driven to move toward the nail tail portion 1c, so that the wire anchor can be stuck in the bone hole and is not easy to fall out. The wire anchor of the present invention has a simple structure and is easy to process and manufacture. The provision of the internal thread 1d simplifies the operation steps of the inserter. The provision of the slot 1e facilitates the cooperation between the inserter and the wire anchor. The provision of the second external thread 1f on the outer surface of the wire anchor facilitates the entry of the wire anchor into the bone hole while also allowing the wire anchor to be better stuck in the bone hole. The shape of the inner wall of the expansion portion 1b is limited, so that the expansion portion 1b expands toward the inner wall of the bone hole. The provision of the slit facilitates the expansion of the expansion portion 1b and also facilitates the bone to pass through the slit and grow into the second through hole. By setting the suture fixing portion as the crossbar 1g, it is convenient to fix the suture on the crossbar 1g. In the utility model of the wire anchor kit, the inserter is simple and easy to operate by setting the first operating rod 2a and the second operating rod 2b. And by setting the second operating rod 2b outside the first operating rod 2a, the inserter structure is made compact. And by setting the first handle 2e and the second handle 2f, the first operating rod 2a is prevented from sliding out of the second operating rod 2b. At the same time, when the first handle 2e abuts the second handle 2f, it is convenient to make the first operating rod 2a rotate around the first operating rod 2a.

[0049] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
