Embodiment 1

[0031] refer to Figure 1-10 , comprising an upper fusion plate 3, the bottom of the upper fusion plate 3 is provided with a lower fusion plate 4, the bottom of the upper fusion plate 3 is fixedly connected with a slide rail 9, and the top of the lower fusion plate 4 is fixedly connected with a slide rail 9 for use Groove 10, the top of the upper fusion plate 3 and the bottom of the lower fusion plate 4 are fixedly connected with several anti-slip teeth 7, one side of the upper fusion plate 3 is fixedly connected with the upper fixing plate 5, and one side of the lower fusion plate 4 is fixed The lower fixed plate 6 is connected, and the upper fixed plate 5 and the lower fixed plate 6 are located in the same vertical direction, the tops of the upper fixed plate 5 and the lower fixed plate 6 are provided with threaded holes 2, and the slide rail 9 is a convex structure, and The slide rail 9 is distributed in an arc-shaped structure, and the slide groove 10 is a concave mechanis...

Embodiment 2

[0034] refer to Figure 1-10 , One side of the upper fusion plate 3 is provided with an upper U-shaped groove 8 , and one side of the lower fusion plate 4 is provided with a lower U-shaped groove 1 .

[0035] Utilizing the upper U-shaped groove 8 on the side of the upper fusion plate 3 and the lower U-shaped groove 1 on the side of the lower fusion plate 4, the prosthesis can have a certain degree of lateral bending activity, allowing the left and right sides of the cervical spine to bend after being installed in place.

Embodiment 3

[0037] refer to Figure 1-10 , the top of the upper fusion plate 3 and the bottom of the lower fusion plate 4 are arc-shaped structures, and the top of the upper fusion plate 3 and the bottom of the lower fusion plate 4 are porous structures.

[0038] The surface of the atlantoaxial repair device in contact with the adjacent vertebral body has a porous structure, which is similar to the structure of the vertebral trabecular bone and helps the growth of bone tissue.

Abstract

The invention relates to the technical field of medical instruments, in particular to a self-adjusting atlantoaxial repairing device, and solves the problems that in the prior art, a mainstream operation mode is still high in operation difficulty, high in complication occurrence rate and serious in consequence, and for an experienced doctor, difficult-to-retrieve complication possibly occurs in an operation, a traditional operation mode does not pay attention to adjustment of cervical curvature, and postoperative cervical deformity severely affects the quality of life. The self-adjusting atlantoaxial repairing device comprises an upper fusion plate, a lower fusion plate is arranged at the bottom of the upper fusion plate, and a sliding rail is fixedly connected to the bottom of the upper fusion plate. According to the self-adjusting atlantoaxial repairing device, a 3D printing atlantoaxial repairing device is creatively introduced, the surface of the 3D printing atlantoaxial repairing device is of a porous structure, bone ingrowth can be achieved without bone grafting, then the purpose of atlantoaxial fusion is achieved, anti-skid teeth are arranged on the upper surface and the lower surface, implanting is easy, withdrawing is not prone to occurring, initial stability is achieved, and necessary conditions are provided for later treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a self-adjusting atlantoaxial repair device. Background technique [0002] Atlantoaxial dislocation caused by atlanto-occipital fusion is a complex deformity of the craniocervical junction, which can lead to compression of the medulla oblongata and high cervical spinal cord, and abnormal curvature of the lower cervical spine. Patients will experience neck pain, limb weakness, and affect quality of life , or even life-threatening, the best treatment is surgery. Currently, there are various treatment options, but several mainstream surgical methods still have high surgical difficulty, high incidence of complications, and serious consequences. For inexperienced doctors, surgery may be difficult. In addition, traditional surgical methods do not pay attention to the adjustment of cervical curvature, and postoperative cervical deformity seriously affects the quality of life. Th...
