[0002] Suture traction osteogenesis is a surgical procedure used to treat fractures or bone deformities. Through a surgical incision, a steel wire or metal instrument is passed through the skin and soft tissue to pull along the bone sutures of the fracture or deformity to restore the normal position and shape of the bone. During the operation, the patient needs to maintain a fixed posture to ensure the correct traction and positioning of the fracture or bone deformity, and then the traction assembly on the head frame is used to restore the patient's bones. However, traditional head frame traction assemblies often use simple springs to achieve traction on the patient's bones through the elasticity of the springs. However, due to the inherent characteristics of the springs, the traction force cannot be adjusted according to the use requirements, resulting in excessive or too small traction force, which cannot accurately meet the patient's fracture or bone deformity treatment needs.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figure 1 , 2 As shown, the utility model provides a head frame for suture traction osteogenesis with an improved traction assembly, including a fixed frame 11, an adjustment rod 21 and an adjustment member 22 on one side of the fixed frame 11, and the two ends of the adjustment rod 21 are rotatably connected to the fixed frame 11 and the adjustment member 22, respectively, to ensure that the adjustment rod 21 can rotate smoothly. Two groups of traction assemblies are arranged below the fixed frame 11, which play a key traction role in the entire head frame. The adjustment member 22 is provided with a mounting hole 23, and the traction assembly is inserted into the mounting hole 23; and one end of the traction assembly is also detachably provided with a traction rope 31, which is an important link with the patient's skull. One end of the strap 12 is fixedly connected to the fixed frame 11 to ensure the stability of the strap 12. The other end is detachably connected to the fixed frame 11, which facilitates the installation and removal of the strap 12 and provides greater convenience for surgical operations.

[0024] like Figure 2 , 3As shown, the traction assembly includes a traction sleeve 41 and a traction rod 42. The traction sleeve 41 is inserted into the mounting hole 23 and is detachably connected to the adjusting member 22 through a screw, which not only ensures the stability of the traction sleeve 41, but also facilitates its disassembly and replacement when necessary. The traction rod 42 is inserted into the traction sleeve 41, and the two cooperate with each other. A limiting groove 43 is provided on one side of the traction sleeve 41. At the same time, a limiting groove 44 is also provided on the traction rod 42 at a position corresponding to the limiting groove 43. In order to further enhance stability, a limiting block 45 is inserted into the limiting groove 43 and then clamped in the limiting groove 44. This makes the movement of the traction rod 42 in the traction sleeve 41 more stable and accurate, and also effectively limits the range of motion of the traction rod 42, ensuring the accurate application of traction force.

[0025] A positioning through hole 46 is provided on the traction sleeve 41, and a plurality of positioning holes 47 are provided on the traction rod 42 corresponding to the positioning through hole 46. When adjusting the traction force, the positioning bolt 48 will pass through the positioning through hole 46 and be clamped in one of the positioning holes 47, so as to realize the positioning of the traction rod 42 in the traction sleeve 41 and ensure the accuracy and stability of the traction force adjustment. A fixing splint 49 is provided at one end of the traction rod 42, and fixing plates 32 are provided at both ends of the traction rope 31. When the traction rope 31 and the traction rod 42 need to be connected, the fixing plate 32 will be clamped between the fixing splints 49. In order to further enhance the stability of the connection, the fixing plates 32 and the fixing splints 49 are provided with limiting holes 33, and the limiting bolts 34 will pass through these limiting holes 33 to firmly fix the two together. Not only the reliable connection between the traction rope 31 and the traction rod 42 is ensured, but also the loosening or falling off during the traction process can be effectively prevented. The operator can adjust the position of the traction rod 42 in the traction sleeve 41 by selecting different positioning holes 47 according to specific treatment needs, thereby adjusting the traction force. At the same time, the cooperation between the fixing splint 49 and the fixing plate 32 and the use of the limit bolt 34 make the connection of the traction rope 31 more firm and reliable, providing a guarantee for the entire treatment process.

[0026] like Figure 2 , 4As shown, a connecting rod 13 is provided on one side of the fixing frame 11, and it and the adjusting rod 21 together form a stable connection structure. The connecting rod 13 and the adjusting rod 21 are provided with connecting grooves 14, and one end of the adjusting rod 21 and the convex part of the adjusting member 22 are respectively clamped in these two groups of connecting grooves 14, so that the connection between them is tighter and more stable. In order to further enhance the firmness of the connection, connecting holes are also provided on the connecting rod 13, the adjusting rod 21 and the adjusting member 22, and the connecting bolt 15 will pass through these connecting holes to fix them tightly together. Such a design ensures that the entire structure will not be loose or shaken during use, providing reliable protection for the traction operation. Multiple groups of positioning columns 16 are also provided on one side of the fixing frame 11. Multiple groups of positioning slots 17 corresponding to them are provided at one end of the binding strap 12. When the binding strap 12 needs to be fixed, the positioning column 16 can be inserted into the positioning slot 17 to achieve rapid fixation of the binding strap 12. It not only facilitates operation, but also ensures the fixing effect of the strap 12, providing the patient with a more comfortable and stable wearing experience. A sponge pad 18 is also thoughtfully provided on the inner side of the fixing frame 11. The sponge pad 18 is soft in texture and can effectively relieve the pressure between the patient's head and the fixing frame 11, increasing the patient's comfort.

[0027] The specific usage and function of this embodiment are as follows:

[0028] When in use, fix the fixing frame 11 on the patient's head, fix one end of the strap 12 to the fixing frame 11, and detachably connect the other end of the strap 12 to the fixing frame 11. According to the position of the patient's skull, connect one end of the traction rope 31 to the fixing splint 49 on the traction rod 42, and the fixing plate 32 is clamped between the fixing splints 49 and fixed by the limit bolt 34 through the limit hole 33. Adjust the position of the traction rod 42 in the traction sleeve 41, and adjust the traction force by selecting different positioning holes 47. Use the positioning bolt 48 to pass through the positioning through hole 46 and clamp it in the corresponding positioning hole 47 on the traction rod 42 to ensure the positioning of the traction rod 42. Match the mounting hole 23 on the adjusting member 22 with the traction assembly so that the traction assembly is inserted into the mounting hole 23. Removably connect the traction sleeve 41 and the adjusting member 22 by screws. On one side of the fixing frame 11, the connecting rod 13 is aligned with the connecting groove 14 on the adjusting rod 21, so that one end of the adjusting rod 21 and the raised part of the adjusting member 22 are respectively clamped in the two sets of connecting grooves 14. The connecting bolt 15 is passed through the connecting holes on the connecting rod 13, the adjusting rod 21 and the adjusting member 22 to fix them together. As needed, the positioning column 16 is inserted into the positioning card groove 17 at one end of the strap 12 to achieve rapid fixation of the strap 12. After the patient wears the head frame, the sponge pad 18 can relieve the head pressure and increase the comfort.

[0029] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
