Problems solved by technology

[0004] The above-mentioned patents have the following problems in practical application: 1. The introduction of the mechanical structure leads to a large increase in the volume of the handle of the endoscope, which may affect the normal operation of the endoscope
2. In principle, optical positioning needs to ensure that there is an unobstructed line of sight between the camera and the positioning ball. This condition will limit the positioning range of the system and may result in multiple unlocatable areas
3. In principle, optical positioning needs to use multiple cameras to complete the positioning task, which will bring unnecessary space pressure to the operating room

Abstract

The invention provides an endoscope system with an anti-interference capacity and a surgical navigation function. A surgical navigation subsystem is realized by an inertial navigation module, and the inertial navigation module comprises three sensors, i.e., a triaxial accelerometer, a triaxial gyroscope and a triaxial magnetometer. Depending on a micro-electro-mechanical system technique, the navigation subsystem can be integrated in a handle of an endoscope, so that the endoscope has a positioning function. In a positioning algorithm, through proper anti-interference treatment, positioning errors caused by external magnetic fields and movement of the endoscope are reduced, and the positioning stability and accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of computer-aided endoscopic surgery navigation. Background technique [0002] With the development of modern medicine, minimally invasive surgery with endoscopic system as the main implementation tool has been widely recognized and rapidly popularized. In order to better achieve the purpose of minimally invasive, doctors must accurately obtain the current posture and position of the endoscope, so surgical positioning and navigation technology is often required. Therefore, modern endoscopic technology and medical navigation technology complement each other, and it is often necessary to cooperate with each other at the same time during surgery. [0003] Chinese patent CN200910198524 discloses a "device combining surgical navigation system with endoscope system and its application", which provides a method for combining optical positioning system with endoscope: through special mechanical The structure fixes...
