Aspirator for transnasal endoscopic intracranial surgery

Abstract

The aspirator for the transnasal endoscopic intracranial surgery comprises a main body part and an operation part connected to the rear end part of a tube main body, and the main body part comprises the tube main body and a snake bone structure arranged at the front end part of the tube main body, the tube main body is provided with a front end part and a rear end part which are opposite to each other. The snake bone structure forms a first bendable part of the aspirator for the transnasal endoscopic intracranial operation, and the bending direction and the bending angle of the first bendable part can be controlled and changed when the first bendable part is located in the cranium, so that the first bendable part can be adjusted in real time according to the actual condition of the operation. In addition, the pipe body can provide support for the snake bone structure, so that the snake bone structure is prevented from being broken.

Description

technical field [0001] The present application relates to the field of medical devices, and more particularly, to an aspirator for transnasal endoscopic intracranial surgery. Background technique [0002] Transnasal endoscopic intracranial surgery is a minimally invasive brain surgery without craniotomy. During the procedure, an endoscope is passed through the body's natural channel, the nasal cavity, into the brain to remove diseased tissue (eg, tumors). Compared with traditional craniotomy, transnasal endoscopic intracranial surgery has smaller incisions, faster recovery, higher precision, fewer complications, and lower surgical risks, which can greatly improve the surgical safety and postoperative comfort of patients. It has become a new and much concerned craniocerebral surgery method. [0003] In transnasal endoscopic intracranial surgery, in order to ensure a clear surgical field of vision, it is necessary to promptly remove blood clots and resected diseased tissue in...

AI Technical Summary

Problems solved by technology

This repeated process not only increases the pain of the patient, but also leads to problems such as cumbersome operation, long operation time, increased operation risk, and the bent part of the aspirator is easily broken.

[0008] In addition, generally, the suction device used for nasal cavity surgery only forms a curved part near the handle, which undoubtedly limits the maneuverability of the end of the suction device into the cranium

Although some suction devices also form a curved part at the end that can enter the cranium, which improves the operational flexibility to a certain extent, but it still does not solve the problem that it is difficult to adjust the curvature and bending of the suction device when it is inserted into the cranium. direction problem
