Abstract

This application is applicable to the field of computer technology, and provides a method and device for detecting the movement of navigation markers during surgery. The method includes: receiving reflected infrared light reflected by the target object during the operation; , determine the first position of the target object; obtain the relative position information between multiple fixed objects on the navigation marker; determine the second position of the navigation marker according to the relative position information; according to the first location and the second location, and detecting whether the navigation marker moves. By using the above method, it is possible to detect in real time whether the navigation marker moves during orthopedic surgery, thereby reducing the risk of surgery.

Description

technical field [0001] The present application belongs to the technical field of computers, and in particular relates to a method and device for detecting movement of navigation markers in an operation. Background technique [0002] In recent years, with the advancement of related technologies such as computers, precision mechanical engineering, image engineering, and medicine, computer-aided surgery has achieved rapid development. Computer-aided surgery technology can help doctors to accurately diagnose the patient's condition; during the operation, the precise position of the surgical tool relative to the affected area can also be clearly observed, so as to guide the doctor to perform the operation quickly and accurately, saving operation time, Reduce surgical trauma. [0003] Taking orthopedic surgery as an example, doctors can use the orthopedic surgery navigation system to assist in completing the surgical process. At present, in the orthopedic surgery navigation syst...
