[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 , 2As shown in Figure 4, the utility model provides a head frame for suture traction osteogenesis with an improved counterweight structure, including a support frame 11, which is the support base of the entire head frame and stably carries the operation of other parts. On both sides of the support frame 11, fixed plates 21 are symmetrically arranged, and these fixed plates 21 are tightly connected to the support frame 11 to form a stable whole. A plurality of groups of fixing screw holes 22 are opened on the fixing plate 21, and these fixing screw holes 22 are neatly arranged, providing a position for the insertion of the fixing screws 23. The fixing screws 23 play a key role in fixing and connecting. The fixing screws 23 are inserted into the fixing screw holes 22 and connected to the patient's skull through the fixing screws 23. A counterweight assembly is arranged on one side of the support frame 11, and the counterweight assembly is detachably connected to the two groups of fixing plates 21, which brings great convenience to the use of the head frame. The operator can easily install or disassemble the counterweight assembly and the fixing plate 21 according to actual needs, so as to perform maintenance, adjustment or replacement operations. A support rod 12 is provided on the bottom surface of the support frame 11, and the support rod 12 provides additional support and stability for the head frame. At the same time, a traction assembly is also provided below the support frame 11, and the traction assembly is sleeved on the support rod 12. The existence of the traction assembly enables the head frame to have the key function of distraction osteogenesis, and can play an important role in the surgical process.

[0024] The counterweight assembly includes a wearing piece 31, and both the wearing piece 31 and the fixing plate 21 present a beautiful arc design, which can better fit the human body structure and provide a more comfortable wearing experience. Buckles 32 are provided at both ends of the wearing piece 31, and a connecting groove 24 is provided on the fixing plate 21 corresponding to the buckle 32. When the counterweight assembly needs to be installed, the buckle 32 only needs to be accurately inserted into the connecting groove 24 to achieve a quick and stable connection. This connection method is simple and convenient, and is convenient for operators to operate. The counterweight assembly also includes multiple groups of counterweight blocks 33. In order to facilitate the placement and management of the counterweight blocks 33, multiple groups of placement bags 34 are provided on the wearing piece 31. These placement bags 34 are evenly distributed on the wearing piece 31, and the counterweight blocks 33 can be easily placed therein. The operator can flexibly select the placement bag 34 to place the counterweight block 33 according to actual needs, thereby achieving the adjustment of the counterweight. In this way, the counterweight assembly can better adapt to different usage scenarios and patient needs, and provide strong support for the performance improvement of the head frame.

[0025] like Figure 2 , 3As shown, the traction assembly includes a traction seat 41, and a through slot 42 is provided on the traction seat 41. The support rod 12 can be smoothly inserted into the through slot 42, which provides a basis for the movement of the traction seat 41. Positioning slots 13 are provided on both sides of the support rod 12, and positioning holes 43 are provided at both ends of the traction seat 41. When the position of the traction seat 41 needs to be adjusted, the operator can pass the positioning bolt 44 through the positioning hole 43 and make it stuck in the positioning slot 13. The traction seat 41 and the support rod 12 are slidably connected, and the operator can easily push the traction seat 41 to move on the support rod 12 to meet different traction requirements. In addition, two groups of traction rods 45 are also provided on one side of the traction seat 41, and a spring 46 is provided at one end of the traction rod 45, and one end of the spring 46 is connected to the traction hook. When the traction operation is carried out, the spring 46 can play a role of buffering and stabilization, making the traction process more stable and reliable.

[0026] like Figure 2 As shown, two groups of studs 14 are symmetrically arranged on both sides of the support frame 11, providing stable support for the connection of the fixing plate 21. A connecting through hole 25 is opened on the fixing plate 21 corresponding to the stud 14. When the fixing plate 21 needs to be installed, the stud 14 only needs to be inserted into the connecting through hole 25 to achieve a preliminary connection. The sliding connection between the fixing plate 21 and the stud 14 provides convenience for the adjustment of the fixing plate 21. The operator can slide the fixing plate 21 on the stud 14 according to actual needs to find the most suitable position. When the fixing plate 21 is adjusted to a suitable position, the stud 14 needs to be further fixed. At this time, the operator sets the fixing nut 26 on the stud 14 and tightens it, so that the fixing plate 21 is tightly connected with the stud 14, ensuring the stability and reliability of the entire structure. A fixing frame 15 is also provided on one side of the support frame 11. A sponge pad 16 is provided on this fixing frame 15, and the presence of the sponge pad 16 provides a more comfortable experience for the patient.

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

[0028] When in use, first place the support frame 11 in a suitable position, and then, according to the size and shape of the patient's head, the operator adjusts the position of the fixing plate 21 on the stud 14 to a suitable position so that the head frame fits tightly with the patient's head. Next, use the fixing nut 26 to fix the fixing plate 21 on the stud 14 to ensure that it is stable and reliable. Fit the wearing piece 31 of the counterweight assembly on both sides of the patient's head so that the buckle 32 is accurately snapped into the connecting groove 24 to complete the installation of the counterweight assembly. According to actual needs, the operator can take out or add the counterweight block 33 from the placement bag 34 to adjust the counterweight. Put the traction seat 41 on the support rod 12 and fix it in a suitable position by the positioning bolt 44. According to the traction requirements, the operator can push the traction seat 41 to move on the support rod 12, and the spring 46 on the traction rod 45 will play a role of buffering and stabilization. The sponge pad 16 on the fixed frame 15 will provide comfortable support for the patient, making the patient feel more comfortable and at ease during the treatment process. The entire head frame is simple and convenient to use, and can provide effective support and protection for suture traction osteogenesis.

[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.
