Neuroendoscope soft channel with a support arm capable of retracting scalp and adjusting skull

Abstract

The invention discloses a neuroendoscope soft channel with the support arm capable of retracting scalp and adjusting skull, and belongs to the technical field of surgical instruments of a neurosurgical neuroendoscope platform. The channel comprises a puncture channel and a fixing arm structure, the fixing arm structure comprises a retracting fixer and a fixing strap, and the puncture channel is connected with the retracting fixer through a fixing strap; due to the fact that the channel is provided with the fixing arm structure, the channel is simple in structure, reasonable in design, easy tooperate and strong in practice, the fixing arm structure is used for neurosurgery, provides a skull fixing platform which can retract the scalp and can be adjusted and fixed during the operation, is connected with the neuroendoscope channel, fixes the neuroendoscope channel in the ideal positions of focus such as intracranial hematoma, tumor and the like, and flexibly adjusts the puncture positions of the channel, the structure is convenient to adjust, good in stability and reliable in fixation, the channel accurately exposes surgical sites during the operation and is minimally invasive, operation time is short, brain tissue damage is effectively reduced, and the channel is beneficial for postoperative rehabilitation of a patient.

Description

technical field [0001] The invention relates to a neuroendoscopic soft channel with retractable scalp and adjustable skull fixing arms, belonging to the technical field of surgical instruments for neurosurgery neuroendoscopic platforms. Background technique [0002] my country has now entered an aging society, and the number of hemorrhagic stroke patients reaches about 5 million per year, mainly due to hypertensive cerebral hemorrhage and ventricular hemorrhage. About 20-30% of patients need surgical removal of hematoma. Traditional surgical methods are the first The disadvantages of large cranial flap removal of hematoma, hematoma cavity, and ventricle drainage are as follows: large cranial flap removal of hematoma artificially aggravates brain injury and many complications; preoperative positioning of blind puncture catheter may cause puncture position deviation damage Peripheral brain tissue can aggravate brain dysfunction, and simple catheter drainage can make the hematoma...

Problems solved by technology

The immaturity of the endoscopic channel has always restricted the application and dissemination of this treatment method

The patent with publication number CN107007333A discloses a visually adjustable neuroendoscopic channel, but the device cannot fix the operating channel, and an endoscope, suction device and other operating instruments need to be placed in the channel during the operation; if the channel is not For effective fixation, when multiple instruments are operated in the channel, it not only affects the stability of the endoscopic image, but more importantly, the stability of the channel is poor when multiple instruments are operated in the channel, and the channel produces rigid displacement during multi-instrument operation. Brain tissue damage; if the optimal position of the channel is not fixed during the operation, it will be displaced due to the operation of the instrument or with the displacement of the brain tissue, and repeated adjustment of the channel position will also increase brain tissue damage; during endoscopic operation The channel is made of rigid material, which cannot adjust various visual fields and operating angles more freely. If the brain tissue is forced to adjust to the best visual field and operating angle, it will be hard displaced and damage the brain tissue.
