Abstract

The invention provides a total knee arthroplasty robot auxiliary system, a control method, electronic equipment, and a computer-readable medium. The auxiliary system comprises a pre-operative planningsystem, an intraoperative planning system and an execution system, wherein the pre-operative planning system is used for formulating pre-operative planning, wherein the pre-operative planning data comprises a knee image; the intraoperative planning system is used for formulating intraoperative planning, wherein the knee image in the pre-operative plan and a knee surface profile determined in theoperation of a patient are subjected to image registration; knee dynamic spacing force line data at a continuous flexion angle is acquired; visual displaying of a dynamic spacing force line data graphis performed; prosthesis planning is adjusted according to the visual display of the dynamic spacing force line data graph to obtain intraoperative planning; and the execution system is used for guiding an osteotomy guide mounted at the operating end of a mechanical arm of the surgical robot to be located in a predetermined position in the planning, wherein the osteotomy guide is used for positioning an osteotomy saw.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a total knee joint replacement surgery robot auxiliary system, a control method, electronic equipment and a computer readable medium. Background technique [0002] In recent years, total knee arthroplasty (total knee arthroplasty, TKA), as an effective clinical procedure for the treatment of severe knee pain, deformity and dysfunction, has been widely carried out at home and abroad. The operation of artificial joint replacement surgery is often decided based on the doctor's experience and estimation, and it is difficult to ensure the accuracy of the prosthesis and the patient's femur and tibia. [0003] Compared with traditional joint replacement surgery, surgical robots can carry out individualized modeling, measurement and design before surgery to ensure accurate and safe operation during surgery, thereby assisting in the completion of individualized and preci...
