Navigation operation system, registration method thereof and computer readable storage medium

Abstract

The invention provides a navigation operation system, a registration method thereof and a computer readable storage medium. The navigation operation system comprises a robot system, a navigation system and a control unit which are in communication connection, wherein the robot system comprises a mechanical arm and is provided with a robot coordinate system established on the mechanical arm; the navigation system comprises navigation tracking equipment; and the navigation system is provided with a base coordinate system which can be identified by the navigation tracking equipment. The navigation operation system is configured as follows: the navigation tracking equipment tracks the position of the tail end of the mechanical arm in space; and the control unit executes kinematic model calibration on the mechanical arm according to the position of the tail end of the mechanical arm in the space, and obtains a first conversion relationship between the base coordinate system and the robot coordinate system according to the calibrated model of the mechanical arm. The navigation operation system can improve the positioning accuracy of the mechanical arm and improve the operation precision.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a navigation surgery system, a registration method thereof, and a computer-readable storage medium. 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 surgic...

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. Inaccurate positioning of the arm during surgery
