Abstract

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.
