A surgical upper computer for a total knee arthroplasty, and a total knee arthroplasty system, in the field of surgical devices. The surgical upper computer includes a processor, and a memory storing which, when executed, enable the processor to execute operating modes of the surgical upper computer, where the operating modes include: exhibiting information to be input, the information to be input including a dynamic change range of a joint flexion angle, and a relationship between the joint flexion angle and a pushing force applied or a gap formed between a femur and a tibia; applying a pushing force during a process of dynamically adjusting the joint flexion angle, and acquiring corresponding relationship data between the pushing force and the gap; and visually exhibiting the corresponding relationship data. Accordingly, the force and gap between soft tissues in the total knee arthroplasty can be acquired and exhibited in a reasonable manner.

Surgical upper computer for total knee arthroplasty, and total knee arthroplasty system

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.
