Brain endoscopic surgery auxiliary system

Abstract

The invention relates to the field of medical instruments, and discloses a brain endoscopic surgery auxiliary system. The auxiliary system comprises an anatomical structure recognition subsystem, a visual electrophysiology collector and an optic nerve electrophysiology early warning subsystem. The anatomical structure recognition subsystem is used for receiving the operation image output by a brain endoscope and recognizing an anatomical structure in the brain endoscopic operation according to the operation image. The visual electrophysiology collector is used for collecting visual electrophysiology monitoring data of a patient in a brain endoscopic surgery. The optic nerve electrophysiology early warning subsystem is used for receiving the visual electrophysiology monitoring data output by the visual electrophysiology collector and achieving early warning of the optic nerve function of the patient according to the visual electrophysiology monitoring data. According to the brain endoscopic surgery auxiliary system, the operation image and the nerve electrophysiology monitoring data are analyzed through the convolutional neural network, the operation image and the nerve electrophysiology monitoring data are fused, the safe brain endoscopic surgery auxiliary system is constructed, and instant recognition of key anatomical structures and timely early warning of optic nerve functions in the brain endoscopic surgery process can be achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an auxiliary system for brain endoscopic surgery. Background technique [0002] Brain endoscopy is an emerging neurosurgical technique in recent years. Its development enables surgeons to remove skull base tumors, which were previously called "surgical forbidden areas", including pituitary tumors, craniopharyngiomas, and chordomas. These tumors compress peripheral nerve tissue, seriously affecting the quality of life of patients, and even threatening their lives. The surgeon inserts the endoscope into the base of the patient's skull through the patient's nasal cavity for surgery, and operates by watching the video output from the monitor. Endoscopy has obvious advantages over traditional microscopic surgery due to its advantages of less trauma and clear surgical field of view. However, skull base tumors often invade key surrounding anatomical structures: the optic nerve anter...

AI Technical Summary

Problems solved by technology

For inexperienced surgeons, it is difficult to grasp key anatomical parts (such as internal carotid artery, optic nerve, etc.)

Once accidentally injured, the consequences will be catastrophic and endanger the lives of patients

[0004] 2. Surgical instruments often touch the optic chiasm during endoscopic surgery. The traction during the operation and the heat conduction of surgical instruments will damage the optic chiasm.

However, conventional visual electrophysiological monitoring requires continuous monitoring by a well-trained electrophysiologist, so there is a certain degree of recognition error and high labor costs
