Full digital total knee arthroplasty robot system and its simulated surgical method

Abstract

The invention relates to a full digital total knee arthroplasty robot system and its simulated surgical method. According to the full digital total knee arthroplasty robot system and a working methodthereof, the system comprises a control computer and a robot, an end effector is mounted on the robot, the end effector operates according to an instruction of the robot, and the control computer controls an action of the robot; and the system further comprises a structured light navigator, a dynamic reference, and a fixing device; the structured light navigator is mounted adjacent to a surgical bed, the fixing device is mounted on the surgical bed, the dynamic reference is mounted on the fixing device, and the structured light navigator is capable of capturing the motion locus of the dynamicreference.

Description

technical field [0001] The invention relates to a fully digital surgical robot system for total knee replacement surgery and a method for performing simulated surgery using the system. Background technique [0002] With the aging of the world population, the incidence of knee joint disease is increasing year by year. In China, the incidence rate of knee osteoarthritis alone is as high as 8.3%. The impact of joint pain and dysfunction on the quality of life of patients cannot be underestimated. The etiology of knee osteoarthritis is complex, and its pathological features are primary or secondary changes in articular cartilage and the resulting degeneration of articular cartilage, changes in subchondral bone, sclerosis of bone lamellar bone, and subsequent appearance of subchondral And marginal osteophyte formation, secondary synovitis, joint capsule contracture, joint space narrowing, causing joint dysfunction and other symptoms. Total Knee Arthroplasty (hereinafter referre...

AI Technical Summary

Problems solved by technology

Traditional surgery uses a mechanical guide to perform intramedullary and extramedullary positioning, and the operator judges the osteotomy, prosthetic position, and soft tissue balance with the naked eye, feel, and experience. Many subjective factors directly affect the accuracy of the operation, and even lead to failure of surgery

[0003] Because the doctor's surgical operation depends on his experience, he is prone to fatigue after a long period of operation, and the accuracy of the operation is relatively poor, especially for doctors or students with little or no actual combat experience who need surgical training and teaching, but in patients It is very dangerous to train or practice on the body, and it is not practical to repeat the operation practice on the patient
