Cervical intervertebral disc scope

Abstract

The invention relates to a cervical intervertebral disc scope, which is mainly applicable to cervical vertebra and cervical intervertebral operations on human bodies. The cervical intervertebral disc scope comprises an objective system, a body device, an ocular system, an instrument channel device, a water delivery device, a lighting device and an external mirror tube, and is characterized by also comprising an image transmitting part, wherein the image transmitting part comprises an image bundle, a short tube, an image bundle rear connector, an image bundle positioning tube and an image bundle regulating screw; one end of the image bundle is matched with the objective system and the other of the image bundle is fixed with the image bundle rear connector through the short tube; the image bundle positioning tube is connected with the body device; the image bundle regulating screw is fixed on the image bundle positioning tube; and the ocular system comprises a microobjective part and a microscopicocular part, an optical duct, an objective tube, a water supply duct and the instrument channel are arranged in the external mirror tube, and the body device comprises a hollow front body and a hollow rear body. The cervical intervertebral disc scope is reasonable in structural design and small in volume, an optical system is insusceptible to breakage, and the service life of the cervical intervertebral disc scope is long.

Description

technical field [0001] The invention relates to a cervical intervertebral disc mirror, which is mainly suitable for the operation of the cervical spine and cervical intervertebral disc of the human body, and belongs to medical equipment. Background technique [0002] The human cervical spine is located between the skull and the thorax, and the cervical intervertebral discs need frequent activities under load-bearing conditions, and are susceptible to excessive minor trauma and strain. The traditional surgical method requires surgical resection of all intervertebral discs in the neck, and then implants metal grafts, artificial discs or bone tissue, which is an open major surgery. Direct opening of the spinal cavity may lead to complications such as nerve adhesions, epidural hemorrhage, nerve injury, or nerve ischemia.
