Total knee arthroplasty robot auxiliary system, control method and electronic device

A total knee arthroplasty robot auxiliary system, comprising:

• a preoperative planning system, configured to formulate a preoperative plan, wherein preoperative plan data comprises an image of a patient knee joint;
• an intraoperative planning system, configured to formulate an intraoperative plan, wherein the knee joint image in the preoperative plan and a knee joint surface contour of the patient determined in an operation are subjected to image registration, knee joint dynamic spacing force line data at a continuous flexion-extension angle is acquired, a dynamic spacing force line data graph is visually displayed, and a prosthesis plan is adjusted according to the visual display of the dynamic spacing force line data graph to obtain the intraoperative plan;
• and
• an executing system, wherein a bone-cutting guide mounted at an operating end of a mechanical arm of a surgical robot is guided to be located in a planned predetermined position according to the intraoperative plan, and the bone-cutting guide is configured to locate a bone-cutting saw.

A total knee arthroplasty robot auxiliary system, comprising:

• an upper controller, a surgical controller, a femur tracer, a tibia tracer, a bone-cutting guide tracer, a scanning probe and a guide camera, wherein
• the upper controller provides a preoperative plan and an intraoperative plan and transmits the intraoperative plan to the surgical robot;
• the femur tracer and the tibia tracer are respectively arranged at a femur and a tibia of a knee joint of a patient, and the navigation camera cooperates with the femur tracer and the tibia tracer to acquire motion track information of the knee joint in the continuous lower limb flexion-extension process during operation;
• the navigation camera cooperates with the scanning probe to acquire surface contour data of the knee joint of the patient;
• the navigation camera cooperates with the femur tracer to acquire position information of the knee joint of the patient;
• one end of the bone-cutting guide tracer is connected to a bone-cutting guide for mounting a bone-cutting tool and the other end of the bone-cutting guide tracer is connected to an operating end of a mechanical arm of the surgical robot, and the navigation camera cooperates with the bone-cutting guide tracer to acquire position information of the bone-cutting guide;
• and
• the upper controller is in communication connection to the robot, the femur tracer, the tibia tracer, the bone-cutting guide tracer and the navigation camera and is configured to generate the intraoperative plan according to the acquired knee joint position information, bone-cutting guide position information, knee joint surface contour data and motion track information at the continuous flexion-extension angle, and
• the robot receives the intraoperative plan and controls the mechanical arm of the robot according to the intraoperative plan, so that the bone-cutting guide is located in a planned predetermined position.
