Navigation surgery system, computer readable storage medium and electronic device

Abstract

The invention provides a navigation surgery system, a computer-readable storage medium and electronic equipment, including a robot system, a navigation system and a control unit connected by communication, the robot system includes a robot arm, and the robot system has a robot coordinate system on the robot arm; The navigation system includes a navigation tracking device and a bone target. The navigation system has a base coordinate system that can be recognized by the navigation tracking device and a calibration target coordinate system; the base coordinate system and the robot coordinate system have a predetermined first conversion relationship, and the calibration target coordinate system There is a predetermined second conversion relationship with the base coordinate system; the control unit identifies the calibration target coordinate system, and determines the position of the mechanical arm in the calibration target coordinate system when the mechanical arm is in the expected pose according to the coordinate system of the bone target; The position of the mechanical arm in the calibration target coordinate system, the second conversion relationship and the first conversion relationship obtain the expected position of the mechanical arm in the robot system coordinate system, thereby ensuring surgical accuracy and expanding the intraoperative operating space.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a computer-readable storage medium and electronic equipment for a navigation operation system. Background technique [0002] Knee osteoarthritis is a common orthopedic disease, the main clinical manifestations are knee joint swelling, pain, swelling, stiffness and so on. There are many causes of knee osteoarthritis. If patients cannot get timely and effective treatment, it is easy to cause a series of complications such as muscle atrophy and knee joint deformity, which will seriously affect the patient's physical and mental health and quality of life. Total knee arthroplasty (total knee arthroplasty, TKA) is currently the most effective method for the treatment of advanced knee osteoarthritis, which can relieve knee pain, restore knee joint mobility, and greatly improve the postoperative quality of life of patients . [0003] In the prior art, the orthopedic surgical ro...

Problems solved by technology

[0003] In the prior art, the orthopedic surgical robot system is usually used for total knee replacement, and multiple targets such as tool targets and base targets are used to determine the coordinate system relationship between the surgical robot and the navigation system, but there are still mechanical problems of the robot.
