The present application provides a total knee arthroplasty robot auxiliary system, a control method, electronic device and a computer readable medium. The auxiliary system comprises: a preoperative planning system configured to formulate a preoperative plan, preoperative plan data including a knee joint image; 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.

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

Provided are an intraoperative planning adjustment method, apparatus and device for TKA (Total Knee Arthroplasty) and a computer-readable medium. The method comprises: importing preoperative planning data; performing image registration on preoperative planning images and the surface contour of a knee joint of a surgical object; acquiring the dynamic spacing force line data of the knee joint at a continuous flexion-extension angle; visually displaying the dynamic spacing force line data graph; and adjusting prosthesis planning according to the visual display of the dynamic spacing force line data. By calculating information such as the joint gap and the force line angle of the lower limb at the continuous flexion-extension angle in the operation, the method provides a comprehensive adjustment information source in the operation for a surgeon, and therefore a better operation planning is obtained.
