Abstract
An osteotomy calibration method, calibration tools, a readable storage medium, and an orthopedic surgery system are provided. Firstly using the plane calibration tool to obtain the calculated position information of the current osteotomy plane, and then determining a position error between the calculated position information and a predetermined position information of a planned osteotomy plane, and if the position error exceeds a preset value, calculating and transmitting a relocation information to a robotic arm to control and relocate the robotic arm. By comparing and identifying the position error between the current osteotomy plane formed by the first osteotomy and the planned predetermined osteotomy plane, relocating the robotic arm, and performing a secondary correction of the osteotomy plane. In addition, by relocating the robotic arm and secondary correction of the osteotomy plane, additional bone nails which is to fix the navigation tool to the bone can be avoided.
