More Information
Summary:A surgical navigation system comprising a spatial positioning marker component (600) on a surgical instrument, a tracer on a bone structure, a binocular camera (501), and a computer (502). The tracer is provided with a navigation tracer surface (200). The spatial positioning marker component (600) comprises a navigation surface (601). The binocular camera (501) is connected to the computer (502), and transmits acquired information of the tracer and the spatial positioning marker component (600) to the computer (502). The computer (502) and a computer readable storage medium each separately store a computer program for performing a surgical navigation method. The method comprises; generating three-dimensional models of a bone and the surgical instrument, and obtaining tracer registration information and calibration information of the spatial positioning marker component (600); receiving real-time information of the tracer and the spatial positioning marker component (600) acquired by the binocular camera (501); and calculating spatial position information of the bone and the surgical instrument, and fusing, in real-time, the information with the three-dimensional models to obtain a dynamic image of a real-time positional relationship therebetween. The invention eliminates intraoperative registration used for surgical navigation, simplifies surgical processes, and improves surgical precision.
