[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figure 1 , 2As shown, this utility model provides a head frame for transsuture traction osteogenesis with an improved adjustable component, including a fixation frame 11. The fixation frame 11 has a stable structure, providing reliable support for the entire head frame. Fixation plates 21 are respectively provided on both sides of the fixation frame 11, and these fixation plates 21 play an important role in connection and fixation. A fixing rod 22 is installed at one end of the fixation plate 21, and the fixing rod 22 is tightly connected to the fixation plate 21. Fixing sleeves 12 are also provided on both sides of the fixation frame 11, and the fixing rod 22 is locked in these fixing sleeves 12, so that the fixation plate 21 can be smoothly and slidably connected to the fixation frame 11, thereby allowing the fixation plate 21 to be adjusted according to the patient's head size, improving the applicability of the head frame. Multiple sets of fastening screw holes 23 are also provided on the fixation plate 21, and the fastening screws 24 are evenly distributed on the fixation plate 21. The fastening screws 24 pass through the fastening screw holes 23, and the contact between the fastening screws 24 and the patient's skull ensures a tight fit between the head frame and the patient's head. The fixing frame 11 is also equipped with a sliding rod 13, which provides a track for the movement of the traction component. Below the fixing frame 11, the traction component is located, which cooperates with the sliding rod 13, fitting onto the sliding rod 13 and moving flexibly up and down along it. This allows the operator to adjust the position of the traction component according to the specific condition of different patients to meet different treatment needs.

[0025] like Figure 2 , 3 As shown, the traction assembly includes a traction block 31 with a traction groove 32. A sliding rod 13 passes through this traction groove 32, allowing the traction block 31 to move smoothly up and down along the sliding rod 13, with a height adjustable according to usage requirements. An adjustment through hole 33 is provided on the traction block 31. An adjustment valve 34 passes through the adjustment through hole 33 and abuts against the sliding rod 13 at one end. By adjusting the tightness of the adjustment valve 34, the movement of the traction block 31 can be controlled and adjusted to meet different treatment needs.

[0026] The traction assembly also includes two sets of traction valves 35, which are respectively located at both ends of the traction block 31. Traction holes 36 are provided at both ends of the traction block 31, and the traction valves 35 pass through these traction holes 36, forming a rotatable connection with the traction block 31. A first spring 37 is also provided at one end of the traction valve 35, and the other end of the first spring 37 contacts the patient via a traction hook. This design allows for a more comfortable and stable traction effect for the patient during traction, thanks to the elasticity of the first spring 37. A limiting groove 14 is also provided at one end of the sliding rod 13, within which a limiting block 15 is engaged. The limiting block 15 plays a crucial limiting role, preventing excessive slippage or instability of the traction block 31 during movement, thus ensuring the safe and stable operation of the entire traction assembly.

[0027] like Figure 2 , 4 As shown, the fixing sleeves 12 on both sides of the fixing frame 11 have positioning through holes 16, and the fixing rod 22 has multiple sets of positioning holes 25. The positioning bolt 26 can pass through the positioning through holes 16 and be locked in one of the positioning holes 25, which can fix and adjust the position of the fixing plate 21 to meet the needs of different patients' skull fixation sizes. On one side of the fixing sleeve 12, a limiting groove 17 is also provided, and at the same time, a corresponding limiting slot 27 is provided on the fixing rod 22. The limiting plate 28 passes through the limiting groove 17 and is locked in the limiting slot 27. This design can further enhance the limiting and fixing effect of the fixing rod 22, ensuring its stability and reliability during use.

[0028] Inside the fixed sleeve 12, two sets of second springs 18 are also provided. These two sets of second springs 18 are located between the fixed rod 22 and the fixed sleeve 12, respectively. The presence of the second springs 18 can provide an outward pushing force to the fixed rod 22, making it easier and more efficient to return to the maximum size when adjusting the fixed size, thus providing great convenience for the operator.

[0029] A support plate 19 is also provided on one side of the fixation frame 11. Both the support plate 19 and the fixation plate 21 have an arc-shaped design. This allows for a better fit to the shape of the patient's head, improving the stability and comfort of the fixation. A sponge pad is also provided on the inner side of the support plate 19. This sponge pad provides the patient with a softer and more comfortable touch, reducing discomfort during treatment.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In use, first, adjust the position of the fixation plate 21 on both sides of the fixation frame 11 according to the patient's head size. Position the fixation plate 21 by sliding the fixation rod 22 within the fixation sleeve 12 and inserting the positioning bolt 26 through the positioning through hole 16 into the appropriate positioning hole 25. Then, pass the fastening screw 24 through the fastening screw hole 23 on the fixation plate 21 to contact the patient's skull, ensuring a stable installation of the head frame. Next, adjust the position of the traction component on the sliding rod 13 according to treatment needs. Control the up-and-down movement of the traction block 31 by adjusting the tightness of the adjusting valve 34, and ensure stable operation of the traction component by using the engagement of the limiting block 15 within the limiting groove 14. Then, pass the traction valve 35 through the traction holes 36 at both ends of the traction block 31 and connect it to the patient via the first spring 37 and its traction hook to begin the transsuture traction osteogenesis procedure.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
