Thoracic and lumbar vertebral posterior prosthesis

Abstract

The present invention relates to a thoracolumbar vertebrae posterior false body which comprises a manual spinous process and a manual vertebral lamina. The manual spinous process is connected with the manual vertebral lamina, and the connection is shape as the connection of the spinous prcess and the vertebral lamina of human body pyramid. Compared with the prior art, the thoracolumbar vertebrae posterior false body can reconstruct the stability of thoracolumbar vertebrae and recover the physical structure and the physical function of thoracolumbar vertebrae posterior column, and can reconstruct the normal anatomical configuration and the function of vertebral canal, and can effectively avoid the possibility of the iatrogenic injury caused by vertebral canal content during operation; the thoracolumbar vertebrae posterior false body integrates spine fusion and non-fusion fixation functions as a whole, the fusion and non-fusion fixation functions are selected and used freely according to the requirement of the operation, and the operation is simple.

Description

Posterior thoracolumbar prosthesis technical field The invention relates to a medical appliance, in particular to a thoracolumbar posterior prosthesis. Background technique The operation for the treatment of thoracolumbar spinal stenosis involves resection and decompression of the entire lamina and bone grafting, which may easily lead to loss of effective bone bed, iatrogenic instability of the thoracolumbar spine, lack of protection of the contents of the spinal canal, and bone grafting. Bone grafts can easily enter the spinal canal and form iatrogenic compression on the spinal cord nerves, leading to surgical failure. Contents of the invention The object of the present invention is to provide a safe and easy-to-operate thoracolumbar posterior prosthesis in order to overcome the above-mentioned defects in the prior art. The purpose of the present invention can be achieved through the following technical solutions: thoracolumbar posterior prosthesis, which is characte...
