Description

Neural scope and video system with monitoring function

Technical Field

Background

Neuroendoscopy is one of the main development directions of modern micro-invasive neurosurgery, and neuroendoscopy is used for observation and operation in the operation. The neuroendoscopy usually has good functions of illumination, imaging and flushing attraction but lacks the function of detecting and positioning nerves, which brings much inconvenience to the neuroendoscopy operation, and medical staff repeatedly changes instruments while performing the operation, resulting in poor time efficiency.

In the course of operation, the neuroelectrophysiology Monitoring (intra-operative neurophysiological Monitoring) utilizes the neuroelectrophysiology and cerebral hemodynamics method to understand the change of electrophysiological signals in the nerve transmission process, understand the change of the metabolic function of the brain tissue and understand the cerebral blood perfusion condition, thereby effectively assisting the operation doctor to understand the integrity of the patient's nerve function in the anesthesia state in real time and comprehensively. In recent years, rapid development of science and technology has greatly promoted development of nerve monitoring in clinical operations, and nerve electrophysiological monitoring in clinical operations is widely applied to various clinical operations of neurosurgery, orthopaedics, spinal orthopedic surgery, cardiovascular surgery and five sense organs, and becomes an indispensable important component for detecting nerve functional integrity, reducing nerve injury and improving operation quality in clinical operations.

A neurostimulation probe is a surgical instrument used for nerve function monitoring and/or diagnostic detection, and is generally used in cooperation with a device (nerve function monitoring device) of a nerve monitoring and diagnostic system. The electrical stimulation signals from the nerve monitoring system are conducted along the nerve stimulation probe to the monitored tissue or implant, and the nerve response to the electrical stimulation signals is further detected. The purpose of this monitoring is not only to determine the safety of the neural function of the target tissue, but also to find a safe threshold to prevent damage to the neural function during surgery. This monitoring is performed continuously during the surgical procedure to avoid any possible surgical procedure error that could result in permanent neurological impairment.

In many cases, the surgeon needs to touch the detection site outside the direct field of view of the operating microscope or the naked eye, because the anatomical site of the patient varies depending on the surgical site. The operation in the operation is, for example: the nerve in the field of vision is easy to be functionally damaged by decompression, traction, implantation of an implant and the like, and the serious consequences of postoperative paralysis or function loss and the like of a patient are caused. The existing nerve probes used clinically have relatively single functions and lack good illumination and imaging assistance.
