[0027] With reference to the drawings, Figure 1 and Figure 2As shown, the embodiment of the present application provides a cervical curvature adjusting device, which comprises a posterior cervical brace support plate 1 and a pushing mechanism. The posterior cervical brace support plate 1 is used to fit the posterior cervical part of a patient and cooperates with an anterior cervical brace support plate to form a cervical brace to wrap the cervical part. The posterior cervical brace support plate 1 is provided with a length-adjustable fixing belt 3. The fixing belt 3 connects the anterior cervical brace support plate and the posterior cervical brace support plate 1 to be fixed to the cervical part. Meanwhile, the posterior cervical brace support plate 1 is also provided with a pushing mechanism which slides up and down. The pushing mechanism comprises a pushing assembly which moves forward and backward perpendicularly to the posterior cervical brace support plate 1. The pushing assembly applies different forward pushing forces to the cervical lesion segment by moving forward and backward. It can be seen that the cervical curvature adjusting device adjusts the position of the pushing mechanism to be aligned with the position of the cervical lesion segment by moving up and down. The pushing assembly applies a forward pushing force to the cervical lesion segment by moving forward and backward, so as to correct the straightened or reverse arch cervical vertebrae. The device can correct different patients with different cervical lesions and has stronger universality.

The posterior cervical brace support plate 1 is provided with a fixing belt 3 adjusting device for adjusting the length of the anterior fixing belt and the posterior fixing belt. The fixing belt 3 adjusting device comprises a shaft sleeve 11 and a fixing belt adjusting bolt 2. The shaft sleeve 11 is fixed perpendicularly to the outer side of the posterior cervical brace support plate 1. The bolt shank of the fixing belt adjusting bolt 2 is rotatably installed in the shaft sleeve 11 through a bearing. An adjusting gear is fixedly installed on the bolt shank. The shaft sleeve 11 is provided with a through slot in a direction perpendicular to the bolt shank. The anterior fixing belt and the posterior fixing belt pass through the through slot respectively. The end of the anterior fixing belt and the posterior fixing belt passing through the through slot is provided with a toothed ring groove 201. The adjusting gear is arranged in the toothed ring groove 201 and the two are in engagement. It can be found that the length of the anterior fixing belt and the posterior fixing belt can be adjusted by rotating the adjusting bolt and using the engagement of the adjusting gear and the toothed ring groove 201.

[0030] Referring to Figures 1 to 5 As shown, the posterior cervical brace support plate 1 is provided with a sliding groove 5 which penetrates from front to back in the up-down direction. The pushing mechanism is arranged in the sliding groove 5 to slide up and down. Specifically, the pushing mechanism comprises a pushing assembly and a sliding block nut 6 for realizing the forward and backward movement of the pushing assembly. The sliding block nut 6 is slidingly arranged in the sliding groove 5. The pushing assembly comprises a top block adjusting bolt 4 and a top block 9. The top block adjusting bolt 4 cooperates with the sliding block nut 6. The top block 9 is arranged at the end of the top block adjusting bolt located on the inner side of the posterior cervical brace support plate. The two are fixedly arranged in one body through an assembly component. Figure 4As shown, the top block 9 has an arc surface that fits the cervical vertebrae, a T-shaped hole at one end of the top block 9 connected to the top block adjusting bolt 4, and one end of the top block adjusting bolt 4 is inserted into the T-shaped hole through the T-shaped head and is fixed by an assembly component. The assembly component includes a fixed plate 8 and a fixed screw 7, the fixed plate 8 is sleeved on the top block adjusting bolt 4, and the top block 9 is fastened as a whole through the fixed screw 7. At the same time, a soft top block outer cover 10 is also sleeved on the surface of the top block 9 to improve the comfort during use.

[0031] Based on the above, the cervical curvature adjusting device provided by the embodiments of the present application can be used to move the top pushing mechanism up and down along the sliding groove 5, so that the top pushing mechanism is located at different cervical vertebra segments, and the front and rear adjustment of the top block 9 is achieved by the cooperation between the top block adjusting bolt 4 and the sliding block nut 6, so as to exert a forward pushing force on the cervical vertebra segment, adjust the cervical curvature, correct the straightened or reverse arch cervical vertebra, and meet the correction of different patients, different cervical vertebra segments, and different extreme conditions, and the universality is stronger.

[0032] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
