Embodiment Construction
[0019] The present invention is suitable for oblique screw internal fixation through the pedicle and the intervertebral disc, and is inserted under the lateral endoscopic channel. After the posterior transpedicular intervertebral disc oblique screw internal fixation was implanted, the nucleus pulposus was bitten off and the upper and lower lamina were ground through the lateral endoscopic approach. Insert the cancellous bone through the large hole 2 of the body of the intervertebral fusion device 1, and the small hole 5 is held by the supporting equipment to reach the intervertebral space through the side channel. 9 Align the front of the oblique screw into the intervertebral space. Under the fluoroscopy of the C-arm X-ray machine, use the X-ray-opaque metal marking pin 8 as a reference to confirm the position of the intervertebral fusion until the adjustment is satisfactory.
