An Operating Channel System for Spine Minimally Invasive Microscopy

Abstract

The invention discloses an operating channel system for a spinal minimally invasive microscope, comprising: an operating channel, the operating channel includes an outer tissue channel and an inner tissue channel, the inner tissue channel is fixedly connected with the outer tissue channel, the tissue The surface of the outer channel is vertically fixed with a fixed handle; the inner core includes a ball head, a ball handle and a connecting plate, and the ball handle is fixed vertically on the surface of the connecting plate, and the ball handle is far away from the connecting plate. One end of the disk is fixedly connected with the ball head; the dura mater pusher is used to cooperate with the operation channel to push away the dura mater tissue and nerve root for protection. This channel cuts the skin and deep fascia and directly places the channel for surgery, reducing the steps of gradually expanding the tissue and then placing the channel, reducing the operation time, and combined with the application of the dura mater pusher, it can be performed under a microscope in a limited space. operation without the risk of damage to the dura mater and nerve roots.

Description

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

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
