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.
