Magnetic navigation positioning system and method based on two-dimensional image and related equipment

Abstract

The invention provides a magnetic navigation positioning system and method based on a two-dimensional image and related equipment, and belongs to the technical field of computer-aided navigation systems.The system comprises a magnetic field generator, a magnetic sensor set, a control box, a puncture device, an upper computer and a C-arm machine, the C-arm machine is used for shooting an X-ray image of a surgical site of a patient and transmitting the X-ray image to the upper computer for processing, and the X-ray image is transmitted to the computer; the upper computer calculates the transformation relation between an X-ray image and a magnetic field coordinate system and the transformation relation between the X-ray image and a patient according to the X-ray image shot by the C-arm machine, plans the correct position of the puncture device in the operation, and assists a doctor in completing the puncture operation according to the position and posture of the puncture device in the magnetic field coordinate system. Through the magnetic navigation positioning system, a doctor can be assisted to accurately drive a guide needle into an operation target position, and the magnetic navigation positioning system is based on a two-dimensional image, so that the doctor and a patient can receive minimum X-ray radiation, and the patient can receive minimum invasion injury.

Description

technical field [0001] The present invention relates to the technical field of computer-aided navigation systems, in particular to a two-dimensional image-based magnetic navigation and positioning system, method and related equipment. Background technique [0002] In recent years, orthopedic surgery has made great progress, and orthopedic surgery has gradually entered the stage of precise and minimally invasive surgery. However, due to the different conditions of patients and different surgical plans, precise nail placement has become the key and technical difficulty of these surgeries. In order to improve the success rate of surgery, various orthopedic navigation systems have been developed and applied, including robot navigation, computer-assisted intraoperative CT 3D reconstruction navigation, C-arm machine navigation, etc. [0003] The above-mentioned robot navigation generally needs to collect 3D data during the operation, which increases the radiation during the opera...
