Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a slotting tool for vertebral body advancement. Background technique [0002] Anterior cervical spondylolisthesis is a common surgical procedure for the treatment of cervical disc herniation, cervical spondylosis of the spinal cord and nerve root, cervical fracture and dislocation, cervical ossification of the posterior longitudinal ligament, cervical vertebral tumors and inflammation. The general steps are: take out the intervertebral discs on both sides of the vertebral body to be moved forward, make grooves on both sides of the vertebral body to be moved forward, and move the vertebral body forward further. At present, the commonly used vertebral body slotting tools include high-speed grinding drill, ultrasonic bone knife or rongeur. However, high-speed grinding drill is easy to damage the vertebral artery, and the slot width is narrow, which is difficult to meet t...
