Embodiment Construction

[0043] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, which do not depart from the scope of the present invention, and the descriptions and drawings therein are essentially for illustrative purposes, rather than limiting this invention.

[0044] The fixation system in the present invention can be made of titanium alloy, PEEK and other materials commonly used in the field, preferably the plate is made of titanium alloy, and the cage is made of PEEK. Such as figure 1 The shown fixation system 1 for the spine includes a plate 2 and a fusion cage 3, the fusion cage is connected to the bottom surface of the plate, and the plate 2 is a bone plate for connecting with bones. A nail hole 5 matched with a screw 4 is provided on the plate, and the cage 3 and the plate 2 are rotatably connected by ...

Abstract

The invention provides a fixation system for the spine, which includes a plate and a fusion device, the fusion device is connected to the bottom surface of the plate, and there are nail holes on the plate that cooperate with screws, and the fusion device and the plate can be connected through a locking structure. rotationally connected. Through the rotatable connection between the cage and the plate, the position of the nail holes on the plate can be adjusted, thereby adjusting the position of the nails. At the same time, the shaping groove makes the bending more convenient and has strong resistance to breaking, thus ensuring the flexible operation and fastening of the fixing system. Stablize.

Description

Technical field [0001] The invention relates to a fixation system, in particular to a fixation system for the spine. Background technique [0002] Due to degeneration, tumors, and fractures and dislocations caused by physical trauma, various injuries may be caused to the human spine. Malformations and lesions of the skull base (near the foramen magnum), atlas, and axis (C0, C1, C2) will cause the atlanto-occipital joint to fuse and shorten the anterior approach, causing the dentate of the axis to move upward to the foramen magnum. The position makes the foramen magnum relatively smaller, the dentate moves up, compresses the brainstem and medulla oblongata, and causes nerve compression symptoms, resulting in syringomyelia and even paralysis and death. The common treatment methods for the above symptoms are anterior cervical spine lysis combined with posterior cervical occipital fusion, anterior cervical approach (in the oral cavity) to loosen the anterior longitudinal ligament an...
