Neuroendoscopic craniocerebral surgical channel device

Abstract

The invention discloses a neuroendoscopic craniocerebral surgical channel device, which comprises a protective sheath and an elastic film tube. The protective sheath comprises a movable half sheath and a fixed half sheath; the movable half sheath comprises a first half barrel, and the side wall of one end of the first half barrel is provided with a first handle in a radial extending manner; the fixed half sheath comprises a second half barrel, and the side wall of one end of the second half barrel is provided with a second handle in a radial extending manner; the tail end of the first handle and the tail end of the second handle are hinged mutually, and lateral openings of the first half barrel and the second half barrel are in opposite arrangement; the first handle is provided with a width adjusting structure, and the width adjusting structure can be driven to enable the first half barrel to move away from or close to the second half barrel; the elastic film tube is in a tubular structure and sleeves the outer surfaces of the movable half sheath and the fixed half sheath. The neuroendoscopic craniocerebral surgical channel device has advantages of simple structure and simplicity and convenience in operation; due to a closed state in puncture, brain tissues can be better protected, compression injuries are alleviated, and postsurgical complications and sequelae can be reduced.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive neurosurgery, and in particular relates to a channel device for neuroendoscopic craniocerebral surgery, which is suitable for carrying out neuroendoscopic minimally invasive surgery for deep brain lesions, such as minimally invasive hematoma removal under neuroendoscopic neuroendoscopy for hypertensive cerebral hemorrhage surgery, neuroendoscopic minimally invasive resection of intraventricular lesions, etc. Background technique [0002] At present, craniocerebral surgery under neuroendoscopy has become an important direction in the development of minimally invasive neurosurgery. The core of this technology is to further reduce the trauma of previous surgical approaches, expand the exposure of the disease, and increase the chance of visually resecting the lesion. Neuroendoscopic surgery can be mainly divided into extrathecal surgery and intrathecal surgery. [0003] In the prior art, a...

AI Technical Summary

Problems solved by technology

The disadvantage is that the sheath tube is rigid and the diameter is too large. When it enters the brain tissue, there will be crush damage to the surrounding area. The components are complicated and need to be supported and fixed. The operation is cumbersome, which is not conducive to emergency surgery.

The disadvantage is that the channel is fixed, which is not conducive to fine-tuning the direction of the field of view during the operation. The operation of re-determining the direction is cumbersome, prolongs the operation time, increases the risk of surgery for patients, and also has the problem that the channel diameter is too large to enter the brain tissue and cause compression damage.
