Robot-assisted hip replacement surgery navigation system

Abstract

The invention discloses a robot-assisted hip replacement surgery navigation system. The system comprises a surgical scheme loading module, a robot preparation module, a femur registration module and a hip bone registration module and an acetabulum grinding module, wherein the surgical scheme loading module is used for supporting surgical scheme management, surgical scheme preview and surgical scheme fine adjustment; the robot preparation module comprises robot preparation operations such as equipment connection state monitoring, end tool mounting, end tool automatic calibration, connecting rod and tracker mounting and mechanical arm automatic calibration; the femur registration module is used for carrying out femur registration and realizing registration of the point cloud data and the femur of a patient; the hip bone registration module is used for carrying out hip bone registration and realizing registration of the point cloud data and the hip bone of the patient; and the acetabulum grinding module is used for grinding the acetabular fossa according to the preoperative plan. The robot-assisted hip replacement surgery navigation system is easy to operate, the complexity of the surgery is reduced, the surgery time is saved, and the precision of the surgery and the integrating degree of actual surgery operation and a surgery plan are improved.

Description

Technical field: [0001] The invention relates to the field of orthopedic medical robots, in particular to a robot-assisted navigation system for hip joint replacement surgery. Background technique: [0002] Robot-assisted surgical navigation is a hot topic in the medical field in recent years, and the navigation system for hip replacement surgery is one of them. At present, the femur registration and hip registration of the major hip replacement surgery navigation systems at home and abroad need to select a large number of feature points (more than 40), which will not only increase the workload of the surgeon in actual clinical application, but also increase the Make operation process too loaded down with trivial details, influence operation precision. Secondly, at present, the main hip replacement surgery systems at home and abroad all use the passive mode of the robotic arm during acetabular grinding and acetabular cup installation. Therefore, the accuracy of the operati...

Problems solved by technology

At present, the femur registration and hip registration of the major hip replacement surgery navigation systems at home and abroad need to select a large number of feature points (more than 40), which will not only increase the workload of the surgeon in actual clinical application, but also increase the Makes the operation process too cumbersome and affects the accuracy of the operation

Secondly, at present, the main hip replacement surgery systems at home and abroad all use the passive mode of the robotic arm during acetabular grinding and acetabular cup installation. performed, so that surgical accuracy cannot be guaranteed

Thirdly, at present, the major hip replacement surgery systems at home and abroad do not provide operation guidance on the femoral side
