Claim 6:
7. The navigation and positioning system of claim 6, wherein if the mechanical arm control module performs the press-fitting operation on the acetabulum and a pressing fitting rod is moved into the acetabulum, the mechanical arm control module is configured to:
start the conical stereotactic boundary, align the anteversion angle and the abduction angle in real time to make the anteversion angle and the abduction angle match with a preoperative planned anteversion angle and abduction angle, and display a matching effect;
wherein the press-fitting operation is stopped when a distance between a head end of the acetabular rasp and a target depth is 0 mm in each direction of an upper and lower direction, an inner and outer direction and a forward and backward direction, while a press-fitting map and the conical stereotactic boundary are updated; and
real-time monitoring of whether the patient moves during the press-fitting operation is performed, and if the patient moves, the mechanical arm performs position compensation in real time, and a guidance is provided to assist in completing the operation in a compensation mode.
