Abstract
A new type of visible light video navigation system was developed based on the research on the C arm tomography. The micron Tracker binocular visual navigation equipment was used to acquire the position information of surgical instrument. The mathematic model of the system was established and simulated in Matlab. The origin of errors was analyzed with the Monte Carlo method and the error control strategy was presented according to the error analysis result. The surgical planning based on close reduction and internal fixation with three cannulated screws was given. Video information was also provided to monitor the status of the tracked objects. The clinical experiment result shows that the navigation system is feasible.
