Inverted insertion type interbody fusion cage under foraminal mirror

Abstract

The invention discloses an inverted insertion type interbody fusion cage under a foraminal mirror and belongs to the field of surgical instruments. The interbody fusion cage comprises a handle, a connecting rod, a loop bar and a fusion cage body, wherein two fixing rods for fixing the fusion cage body are arranged on one side, away from the loop bar, of a fixing seat; the fusion cage body is of abullet-shaped structure, inverted teeth are arranged on upper and lower surfaces of the fusion cage body, fixing grooves are further formed in two sides of the tail end of the fusion cage body, a thread groove is formed in the middle of the tail end of the fusion cage body, a clamp fork fixing assembly is arranged at one end of a hollow part of the connecting rod, an external thread is arranged ata solid part of the connecting rod and can be connected with the fusion cage, after the hollow part of the connecting rod is connected with the fusion cage body, the connecting rod can be inserted ina spine endoscope instrument channel, the solid part of the connecting rod with the handle is sleeved into the tail end of the fusion cage from the hollow part of the connecting rod via the endoscopeinstrument channel, and the external thread is connected with the internal thread of the fusion cage. The inverted insertion type interbody fusion cage can be used under the foraminal mirror, so thata doctor can observe the placement position of the fusion cage more clearly.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to an inversely insertable intervertebral foramen-endoscopic intervertebral fusion device. Background technique [0002] Degenerative lumbar diseases include intervertebral disc herniation, spinal stenosis, segmental instability, degenerative spondylolisthesis, and degenerative scoliosis, which are common diseases in middle-aged and elderly people. It has become a consensus that lumbar fusion is required for those with intervertebral instability while decompression and internal fixation are performed. The purpose of lumbar interbody fusion is to prevent the further development of instability and degeneration, and to reconstruct the stability of the spine through surgical methods to promote the recovery of the vertebral body. In the process of fusion, due to the differences between individual patients, the size of the fusion cages required is also different. Some patients need to ...
