    Abstract: A navigation system and method for joint replacement surgery, the system comprising: a pre-operative planning module (1), configured to perform segmentation and reconstruction on the basis of acquired hip joint medical image data to obtain a hip joint three-dimensional model, and perform pre-operative planning to determine the position, size, and angle of a prosthesis placement; and a navigation alignment module (2), configured to determine the spatial position of the pelvis and femur on the basis of a pelvis reference frame and a femoral reference frame, perform alignment on the hip joint three-dimensional model on the basis of the spatial position relationship between a surgical probe and the pelvis reference frame and femoral reference frame to obtain a hip joint physical model, and control a surgical instrument clamping the prosthesis to place the prosthesis in the hip joint on the basis of the hip joint physical model. By means of the pre-operative planning of information such as the surgical access and prosthesis placement, and tracking the surgical instrument during the surgery by means of a spatial positioning method, the accuracy of surgery is improved and navigation support is provided to the physician, making the surgery safer and more efficient.

    Abstract: The present application provides a joint replacement surgical robot navigation and positioning system and method. The system includes a preoperative planning module, which is used to: perform segmentation and reconstruction for a hip joint to obtain a three-dimensional model of the hip joint according to obtained medical image data of the hip joint, and carry out a preoperative planning to determine a surgical scheme according to the three-dimensional model of the hip joint; an optical navigation and positioning module, which is used to: generate a navigation instruction according to the surgical scheme, register the three-dimensional model of the hip joint to obtain a hip joint entity model according to spatial position relationships among an optical positioning device, a hip joint of a patient and a surgical probe, match the hip joint entity model with the preoperative planning model, and determine a surgical position on a bone of the patient according to the hip joint entity model; and a mechanical arm control module, which is used to: move an end effector to the surgical position on the bone of the patient, and control the end effector to perform osteotomy, rasion, and press-fitting operations on the hip joint according to the navigation instruction. Preoperative planning is executed through the orthopedic surgical robot, surgical operation is completed at a high level, the operation intensity of surgeons may be greatly reduced, the operation time is saved, and the operation accuracy is improved.
