Abstract

The invention provides an electromagnetic positioning marking device as well as an electromagnetic positioning system and method. The device comprises a sensor positioning mounting block, an upper cover covering the sensor positioning mounting block, a first positioning sensor and a second positioning sensor, wherein a positioning hole allowing metal marking points to be movably embedded is further formed in the sensor positioning mounting block; the first positioning sensor and the second positioning sensor are fixed in the sensor positioning mounting block, the first positioning sensor, the second positioning sensor and the center of the positioning hole are located on the same plane, and the positioning hole is formed in the midpoint position of a connecting line of the first positioning sensor and the second positioning sensor. A six-DOF (degree of freedom) sensor is synthesized through two five-DOF positioning sensors, and the manufacturing cost is low; besides, work for manually finding the point by a doctor is omitted, the operation procedure is simplified, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to an electromagnetic positioning marking device, an electromagnetic positioning system and a method, and belongs to the technical field of medical imaging. Background technique [0002] At present, the surgical navigation system can help doctors complete various surgical operations better. Its function is to use CT scans to obtain images and track the position of surgical instruments in the mapping system in real time. In surgical navigation, the establishment of the image coordinate system (using the coordinate system conversion of the electromagnetic positioning system) is a very critical link. This link is mainly to realize the position conversion of the surgical instrument from the electromagnetic positioning system to the image system. What is tracked in real time is the relative position of the surgical instrument and the human body, which is consistent with the actual situation. [0003] The electromagnetic positioning sy...
