Abstract

This application discloses a precision positioning method for the end effector of a cooperative robotic arm. The method uses two positioning frames for navigation and positioning: the terminal positioning frame is used for precise positioning; real time monitoring. There will be errors in the movement of the robotic arm. Use the navigation device to achieve multiple calibrations, recursively, and approach the exact position, so as to ensure higher accuracy to the maximum extent. During the navigation and positioning process, the body positioning frame can provide the real-time position of the end of the medical device and the space pose difference between the target cutting plane, and feed back to the operator through the screen of the host, and make fine-tuning through visual prompts, and stop if it exceeds a certain threshold swing.

Description

technical field [0001] The present application relates to the technical field of computer-aided surgery, and in particular to a computer-aided surgical navigation system using cooperative robotic arms, and a device, method and system for precise positioning of medical instruments in the surgical navigation system. Background technique [0002] With the development of computer technology, the computer-aided surgical operation system is also developing rapidly. In this type of system, in order to facilitate operations such as movement, a cooperative robot arm is usually set up. The main difference between the collaborative robotic arm and other types of robotic arms is that when using the collaborative robotic arm, the operation process can directly push, pull, lift, and press the robotic arm through human hands. Using the collaborative robotic arm makes The control mode of the end effector or medical equipment is more flexible, and it has better adaptability to complex scenes...
