METHOD FOR POSITIONING AND NAVIGATION OF A FRACTURE CLOSED REDUCTION SURGERY AND POSITIONING DEVCIE FOR THE SAME

摘要

The present invention relates to a method for positioning and navigation of a fracture closed reduction surgery, comprising: installing preoperative positioning devices (1), performing CT-scanning to obtain image information of broken bones and the preoperative positioning devices; determining data information of broken bone segments and of positioning balls of the preoperative positioning devices (1); taking a broken bone segment and a preoperative positioning device (1) as a group to divide the obtained data information into data groups, determining ball center coordinates of the positioning balls (9); determining a matching relation between each preoperative positioning device (1) and the corresponding broken bone segment based on the ball center coordinates of the positioning balls (9); detaching the preoperative positioning devices (1), and installing intraoperative positioning devices (11); identifying indicator balls (14) of the intraoperative positioning devices (11) using infrared light tracking to determine ball center coordinates of the indicator balls in each intraoperative positioning device (11).
