A kind of cervical spine single-door operation lamina rotation lifter

Abstract

The invention discloses a vertebral plate rotating opener for a cervical vertebra single-door operation. The vertebral plate rotating opener comprises a support plate. A moving rod is movably mountedon the inner side of the support plate. A sliding groove is formed in the side wall of the moving rod. A sliding column is slidably connected with the sliding groove. A movable ring is fixedly installed at the outer end of the sliding column. A sliding support is fixedly connected with the top of the outer side of the movable ring. A supporting handle is fixedly installed in the center of the topend of the sliding support. A handle is slidably installed at the top end of the moving rod. The handle rotates along with a movable shaft. When the handle is inward kneaded, the moving rod is supported outwards. An extension spring is arranged at the right end of the moving rod. When the handle is kneaded, the moving rod bears the tensile force of the extension spring, so that the moving force ofthe handle is balanced. The situation that the moving rod is shoved away by a large distance due to overexertion of the handle to expand the vertebral plate of a patient is avoided. The strength of supporting the handle by medical staff in the operation process can be relieved. The strength of fingers is saved, and shaking caused by strenuosity is avoided.

Description

technical field [0001] The invention relates to the technical field of cervical single-door surgery, in particular to a rotary lifter for cervical single-door surgery. Background technique [0002] When cervical spine single-door surgery is performed, use a scalpel to make an opening at the position of the lamina. When cutting the inside of the lamina, it is necessary to keep the lamina in a permanent open state, so that it is convenient for medical staff to operate on the inside of the affected area. Support a sliding opening, use a special lifter for the lamina to prop up from the crack in the middle of the opening of the affected area, and spread it to both sides along the opening, exposing the inner part of the lamina to the visible part of the view. Control is required during operation The strength of the hand. [0003] During operation, the hand of the medical staff needs to stretch the lamina lifter outwards, and the part at the top of the lifter needs to be supporte...

AI Technical Summary

Problems solved by technology

[0003] During operation, the hand of the medical staff needs to stretch the lamina lifter outwards, and the part at the top of the lifter needs to be supported outwards by the fingers. It is easy to be unable to hold on to the long-term support force of the hand. It will be difficult to control the force, and it will relax or stretch the patient's surgical incision wound, which will bring certain errors to the patient's lamina incision, and it is easy to touch the surrounding nerve tissue, which is not conducive to the safety of the patient during the operation. sex
