Description

Technical Field

[0001] This utility model relates to the field of seam-mounting nail technology, and in particular to a seam-mounting nail. Background Technology

[0002] Hallux valgus is a common foot deformity. In surgical correction, besides metatarsal osteotomy combined with soft tissue release, a wedge osteotomy (Akin osteotomy) at the base of the proximal phalanx is often used to enhance the corrective effect. Akin osteotomy has been accepted and recommended by scholars both domestically and internationally. After Akin osteotomy, staples are often used to fix the osteotomy ends. Currently, most staples used to fix these tiny bones are book staple-like staples. These staples cannot create effective pressure at the osteotomy ends, which is detrimental to bone healing; secondly, the fixation is not secure and they are prone to dislodgement; furthermore, the spacing between the two staple legs is difficult to control during drilling, increasing the surgical difficulty and time, and affecting the surgical outcome. Therefore, there is a need for a staple that can create effective pressure at the osteotomy ends, provide secure fixation, and is easy to operate and precisely fix during surgery. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a suture nail that has the characteristics of strengthening the fixing strength, not being easy to fall out, being easy to control the spacing, ensuring the pressure at the bone joint, and improving the bone healing effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a crossbar, including a single leg and a docking hole. One end of the crossbar is bent downward to form a vertically downward single leg. The other end of the crossbar is provided with a horizontally arranged docking hole. The docking hole is elliptical. A conical structure with a larger top and a smaller bottom is provided on the end of the docking hole opposite to the single leg. A docking screw is vertically installed on the docking hole. The lower side of the cap of the docking screw is provided with a docking conical surface that matches the conical structure.

[0005] In this technical solution, a crossbar is used as a support structure for connecting two bones. One end of the crossbar is fixed to the first bone segment by setting a single leg. The connecting screw and connecting hole facilitate the connection of the second bone segment. The connecting conical surface on the connecting screw and the conical structure on the connecting hole match each other, so that when the connecting screw is driven in, pressure is applied to the second bone segment through the connecting conical surface and the conical structure, thereby ensuring that a certain pressure is formed between the first and second bone segments, effectively improving the bone healing effect.

[0006] As a supplement to this technical solution, the single leg and the crossbar are integrally formed.

[0007] As a supplement to this technical solution, the length of the single leg is between 10 mm and 20 mm.

[0008] As a supplement to this technical solution, the connecting screw is a common cortical bone screw.

[0009] Beneficial Effects: This utility model relates to a suture nail, which uses a crossbar as a support structure for connecting two bones. A single foot is used to fix one end of the crossbar to the first bone segment. A connecting screw and a connecting hole facilitate the connection of the second bone segment. The matching of the connecting conical surface on the connecting screw and the conical structure on the connecting hole allows pressure to be applied to the second bone segment when the connecting screw is driven in, ensuring sufficient pressure between the first and second bone segments. This effectively improves bone healing. The device is advantageous for applying pressure to the osteotomy end, providing firm fixation and preventing pull-out. It also allows for precise drilling, is simple to operate, shortens surgical time, and improves surgical efficacy. Attached Figure Description

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0017] The embodiments of this utility model relate to a seam fastener, such as... Figure 1As shown in Figure 5, the device includes a crossbar 1, a single leg 2, and a docking hole 3. One end of the crossbar 1 is bent downwards to form a vertically downward-facing single leg 2. The other end of the crossbar 1 is provided with a horizontally arranged docking hole 3. The docking hole 3 is elliptical in shape. A conical structure 4, which is larger at the top and smaller at the bottom, is provided on the end of the docking hole 3 opposite to the single leg 2. A docking screw 7 is vertically installed on the docking hole 3. The bottom side of the cap of the docking screw 7 is provided with a docking conical surface 8 that matches the conical structure 4.

[0018] In this technical solution, a crossbar 1 serves as the connecting structure for supporting two bones. A single foot 2 is used to fix one end of the crossbar to the first bone segment 5. Connecting screws 7 and connecting holes 3 are used to facilitate the connection of the second bone segment 6. The connecting conical surface 8 on the connecting screw 7 and the conical structure 4 on the connecting hole 3 are matched so that when the connecting screw 7 is driven in, pressure is applied to the second bone segment 6 through the connecting conical surface 8 and the conical structure 4, thereby ensuring that a certain pressure is formed between the first bone segment 5 and the second bone segment 6, effectively improving the bone healing effect.

[0019] As a supplement to this technical solution, the single leg 2 and the crossbar 1 are integrally formed.

[0020] As a supplement to this technical solution, the length of the single leg 2 is between 10 mm and 20 mm.

[0021] As a supplement to this technical solution, the connecting screw 7 is a common cortical bone screw.

[0022] Example

[0023] After osteotomy and correction, the crossbar 1 with a single foot 2 in this technique is drilled and nailed into the base of the proximal phalanx. After the osteotomy end is repositioned, the other end of the crossbar 1 is crossed over the osteotomy end and driven into the docking screw 7 through the docking hole 3. The docking conical surface 8 on the docking screw 7 will compress with the conical structure 4, causing the first bone segment 5 and the second bone segment 6 to come closer together, thereby creating a certain pressure between the first bone segment 5 and the second bone segment 6, effectively improving the bone healing effect.
