Claim 5:
6. An orthopedic surgery system, comprising a control device, a navigation device, a robotic arm, and an osteotomy calibration device, wherein the osteotomy calibration device comprises an acquisition unit and a position tracking unit, wherein: the acquisition unit is configured to acquire a position information of a current osteotomy plane; the position tracking unit is connected to the acquisition unit, and the position tracking unit is configured for position tracking by a navigation device; each of the position information of the current osteotomy plane acquired by the acquisition unit and a position information of the position tracking unit in the navigation device is used to determine a calculated position information of the current osteotomy plane;
wherein the navigation device matches with the position tracking unit of the osteotomy calibration device so as to obtain a position information of the position tracking unit and feedback the position information to the control device; and
wherein the control device is configured to obtain the calculated position information of a current osteotomy plane according to the position information of the position tracking unit of the osteotomy calibration device, and to determine 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, the control device drives and relocates the robotic arm.
