Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a positioning mechanism for intervertebral disc surgery.
Background
Intervertebral disc (intervertebral disc) the cartilaginous junction between the vertebral bodies of two adjacent vertebrae, called the intervertebral disc, consists of a peripheral annulus fibrosus and a central nucleus pulposus, which, for the elderly, can cause a shortening of the height due to intervertebral disc atrophy. When the spine moves, the intervertebral disc has the characteristics of wedge-shaped deformation and horizontal movement of nucleus pulposus, so that when the intervertebral disc is rotated or laterally bent, the intervertebral disc is extruded and thinned at the same side, and at the same time, the opposite side is acted by tension, tension and torsion forces. When this force exceeds the force capacity of the disc, the annulus fibrosis is damaged and the nucleus pulposus spills out. The herniated nucleus pulposus protrudes into the intervertebral foramen or spinal canal and presses on the spinal nerve root, causing a series of symptoms of herniated disc. In the middle-aged and the elderly, the intervertebral disc is degenerated to weaken its elasticity and toughness, and if the upper body is bent and rotated too hard, it is easy to cause prolapse of intervertebral disc.
The existing treatment means for treating the intervertebral disc mainly comprises an operation, but a fixing mechanism is lacked when the intervertebral disc operation is carried out on the neck, and the overall operation effect can be influenced if the neck of a patient moves in the process of the intervertebral disc operation.
