Abstract

The invention relates to a universal locking anterior cervical fixing steel plate, which comprises a fixing steel plate body and ball head locking screws, a plurality of ball head fixing threaded holes are evenly formed in the fixing steel plate body, and outer ball head threads are arranged at the large head ends of the ball head locking screws. The plurality of ball head locking screws are fixedly connected with the fixed steel plate, are respectively inserted into the plurality of ball head fixing threaded holes of the fixed steel plate, and are in threaded connection with the ball head fixing threaded holes through the outer ball head threads at the large head end; and each ball head fixing threaded hole can be in threaded fit with the outer ball head at the large head end of the ballhead locking screw, so that the effects of angle adjustment and locking are achieved.

Description

technical field [0001] The invention belongs to the field of cervical spine fixation devices, in particular to a universal locking anterior cervical spine fixation steel plate. Background technique [0002] Anterior cervical fixation plates are mainly used for internal fixation in the treatment of degenerative disc disease, cervical spondylolisthesis, cervical spinal stenosis, cervical tumors, failure of cervical joint fusion, formation of cervical pseudarthrosis, and cervical deformity. Anterior cervical fixation plate internal fixation is a better method for stabilizing the cervical spine in anterior cervical surgery. It can reliably fix the bone graft, promote fusion, effectively maintain the natural physiological curvature of the diseased cervical spine, and restore the normal physiological function of the cervical spine. . The anterior cervical fixation plate needs to meet the principles of internal fixation such as low notch, anti-retraction locking, narrow width, and...
