Operation channel system for spine minimally invasive microscope

Abstract

The invention discloses an operation channel system for a spine minimally invasive microscope, and the system comprises an operation channel which comprises an external tissue channel and an internal tissue channel, the internal tissue channel being fixedly connected with the external tissue channel, and the surface of the external tissue channel being vertically and fixedly provided with a fixed handle; an inner core, comprising a ball head, a ball head handle and a connecting disc, the ball head handle being vertically and fixedly installed on the surface of the connecting disc, and the end, away from the connecting disc, of the ball head handle being fixedly connected with the ball head; and a dura mater pushing device, used for being matched with the operation channel to push and protect dura mater tissues and nerve roots. After skin and deep fascia are cut open, the channel is directly placed for an operation, the step of expanding tissue step by step and then placing the channel is reduced, the operation time is shortened, operation under a microscope can be carried out in a limited space in combination with the application of an epidural pushing device, and the risk of damaging the epidural and nerve roots is avoided.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, in particular to an operating channel system for a spinal minimally invasive microscope. Background technique [0002] In recent years, minimally invasive techniques in spinal surgery have made considerable progress and become the future direction of development. Compared with traditional spinal surgery, minimally invasive techniques have the advantages of shorter operation time, less intraoperative bleeding, less postoperative drainage, and faster recovery. , good stability of the spine, etc. Before minimally invasive surgery, it is necessary to cut the skin and deep fascia and place a channel for surgery, and then assemble the dura mater pusher to push the dura mater tissue and nerve roots away for protection, avoiding the operation process Injury to the dura mater and nerve roots. [0003] In the process of placing the existing channels, medical personnel need to expand t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following disadvantages in the prior art. During the installation process of the existing channel, medical personnel need to expand the tissue step by step and then install the channel. There are many steps and are relatively cumbersome, thereby increasing the time for the operation, and also Increased the difficulty of the operation, leading to some unnecessary risks, and a proposed operating channel system for spinal minimally invasive microscopy
