Description

Technical Field

[0001] The utility model belongs to the technical field of osteogenesis, and more specifically, particularly relates to a head frame used in suture traction osteogenesis. Background Art

[0002] Suture traction osteogenesis is a surgical technique that lengthens or widens bones by slowly pulling the sutures. It is usually used to treat diseases such as craniofacial deformities. By gradually applying traction force, bone growth and remodeling are promoted to achieve the purpose of improving appearance and function. During the implementation of suture traction osteogenesis, in order to ensure that a better osteogenesis effect can be obtained, an important auxiliary tool, the head frame, is often used. It can provide reliable support for the subsequent traction process, ensure that the traction force can act evenly on the bones, promote bone growth and remodeling, and thus achieve a more ideal osteogenesis effect. The head frame contacts the patient's bones through the fixing screws on it. However, the fixing screws on the traditional head frame are usually arranged in a straight row, and the contact area with the patient's bones is small, which may cause the head frame to be not fixed firmly enough and easily loosen during the operation, thereby affecting the effect and safety of the operation.

[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, the utility model provides a head frame used for suture traction osteogenesis, including a skull frame, which is composed of a main frame 11 and two groups of fixing rods 21. The main frame 11 and the fixing rods 21 are both arc-shaped, and the arc-shaped main frame 11 and the fixing rods 21 can fit the shape of the skull better. The main frame 11 and the fixing rods 21 are connected together to form a stable whole, ensuring the coordination and stability between the two. On the fixing rod 21, there are multiple groups of orderly arranged fixing screw holes 22. These fixing screw holes 22 are distributed in a unique fan-shaped and zigzag shape. This distribution method not only increases the number of fixing screw holes 22, but also allows the fixing screws 12 to form a wider strip-shaped fixing surface with the outside of the skull after being tightened in place. The skull frame and the skull are more closely matched, and the connection stability between the head frame and the skull is further enhanced. On one side of the fixing rod 21, multiple groups of fixing screws 12 are arranged. These fixing screws 12 are inserted into the fixing screw holes 22. By tightening the fixing screws 12, the head frame can be firmly fixed to the skull, ensuring that there will be no shaking or displacement during the operation. This stable fixing method provides a reliable guarantee for the smooth progress of the operation. At the same time, one group of fixing rods 21 is provided with a fixing assembly, and the other group of fixing rods 21 is provided with a strap 23. The cooperation between the two further enhances the stability of the head frame. The strap 23 can be clamped in the fixing assembly to form a more secure connection method, which effectively prevents the head frame from loosening or slipping, making the head frame more stable and reliable during use.

[0024] like Figure 3 As shown, the fixing assembly includes a fixing seat 31, and a fixing plate 24 is also provided at one end of one set of fixing rods 21, and the fixing plate 24 is fixedly connected to the fixing seat 31 to form a whole. The fixing assembly also includes a fixing card plate 32, and the fixing card plate 32 is clamped between the fixing seats 31. Fixing through holes are provided on the fixing card plate 32 and the fixing seat 31, and the rotating shaft 33 is penetrated in these fixing through holes, so that the fixing card plate 32 and the fixing seat 31 can be rotatably connected, so that a fixing cavity is formed between the fixing card plate 32 and the fixing seat 31, and the bandage 23 is penetrated in this fixing cavity. On one side of the fixing card plate 32, multiple groups of fixing teeth 34 are also provided, and these fixing teeth 34 are neatly arranged in the fixing cavity. When the bandage 23 is penetrated in the fixing cavity, the fixing teeth 34 can be tightly clamped on the bandage 23 to form a more secure connection method, which not only increases the fixing strength of the bandage 23, but also further improves the stability of the head frame.

[0025] like Figure 2 , 4As shown, in the skull support, connecting grooves 13 are respectively provided at both ends of the main frame 11, and a connecting block 25 is provided at one end of the fixing rod 21, and the connecting block 25 is clamped in the connecting groove 13. Connecting holes are also provided on the main frame 11 and the connecting block 25. The connecting bolt 14 is inserted into these connecting holes. In this way, the fixing rod 21 and the main frame 11 are rotatably connected, so that the skull support has greater flexibility and adaptability, and can better adapt to the shape and angle requirements of different patients' skulls. The inner side of the main frame 11 is also provided with a mounting groove 15, and a sponge pad 16 is provided on one side of the main frame 11. The sponge pad 16 is clamped in the mounting groove 15, which can provide a more comfortable wearing experience for the patient. An assembly block 17 is provided on one side of the main frame 11, and an assembly groove 18 is provided on the assembly block 17. The skull support is connected to the traction device through this assembly groove 18, ensuring that the connection between the skull support and the traction device is stable and reliable, providing a guarantee for the smooth progress of the operation.

[0026] The specific usage and function of this embodiment are as follows:

[0027] When in use, first assemble the main frame 11 and two groups of fixed rods 21 together to form a stable whole. According to the shape and size of the patient's skull, adjust the position of the fixed rod 21 so that it fits the skull more closely. Then, through the multiple groups of orderly arranged fixed screw holes 22 on the fixed rod 21, select a suitable position to insert the fixed screw 12, and tighten the fixed screw 12 to firmly fix the head frame on the skull to ensure that there will be no shaking or displacement during the operation. The straps 23 on one group of fixed rods 21 can cooperate with the fixed components on the other group of fixed rods 21, and the straps 23 are clamped in the fixed cavity of the fixed component. In the fixed cavity, the fixed teeth 34 can be tightly clamped on the straps 23 to further enhance the stability of the head frame. At the same time, the relative position of the fixed rod 21 and the main frame 11 can be adjusted by the connecting bolt 14 as needed to obtain better adaptability. The sponge pad 16 is installed in the inner mounting groove 15 of the main frame 11 to provide a comfortable wearing experience for the patient. Finally, the skull support is connected to the traction device through the assembly groove 18 on the assembly block 17 to ensure smooth operation.

[0028] 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.
