Lifters for Laminae

Abstract

The invention relates to an opener for a vertebral plate, and effectively solves the problems in a cervical posterior operation of inconvenience in use, difficulty in operation and poor effect in an operation of pushing a door opening side and opening the vertebral plate and occurrence of a dangerous accident caused by easiness in springback when the vertebral plate is opened. The opener is characterized in that the front part is L-shaped; a bending position of the front part is used as a first vertex; the rear end of a long edge of the front part is obliquely connected with the upper end of a connecting section; the connecting section and a short edge of the front part are mutually, oppositely and respectively arranged at two sides of the long edge of the front part; the lower end of the connecting section is obliquely connected with a handle; the handle and the long edge of the front part are mutually, oppositely and respectively arranged at two sides of the connecting section; the central lines of the front part, the connecting section and the handle are located in the same plane; a connecting position between the connecting section and the handle is used as a second vertex. The opener for the vertebral plate, disclosed by the invention, has the advantages that the structure is simple, the use is convenient, the operation is easy, the working efficiency is high, the springback problem caused when the vertebral plate is opened is solved, and the operation safety is increased.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a lifter for a lamina. Background technique [0002] Due to the continuous improvement and promotion of anterior cervical surgery, clinically good results have been achieved in the treatment of lower neck and short-segment cervical myelopathy, but it is still extremely difficult to solve multi-segment cervical myelopathy. Therefore, posterior cervical surgery has become a common surgical method for the treatment of multi-segment cervical spondylotic myelopathy. Posterior surgery is to expand the spinal canal and rely on the existence of the physiological radian. The spinal cord moves backward under the action of the "bowstring principle" to relieve the compression of the spinal cord by the anterior constrictor. [0003] At present, the surgical steps of posterior cervical surgery are as follows: the patient is placed in a prone position, the neck is flexed, and the upper body is raised. ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a lifter for the lamina, which can effectively solve the problem of rongeurs in the operation of pushing the door open and lifting the lamina in the posterior cervical surgery. It is inconvenient to use, difficult to operate, and the effect is poor. When the lamina is lifted, it is easy to rebound, causing dangerous accidents.
