Evaluation on Surgical Robotic Pose Repeatability Based on Laser Tracking Measurement / 中国医疗器械杂志

To provide accurate information for registration and safety evaluation of surgical robot, the pose repeatability measurement method was proposed. According to the terminal instrument of the master-slave surgical robot (such as high-frequency electric knife, ultrasonic knife), a suitable target ball fixture was designed. The node data at 10%, 50% and 100% rated speed were measured respectively. Through data analysis, the pose repeatability property of the tested samples at different speeds was obtained. It has high applicability and repeatability, and can meet the requirements of data traceability and registration testing.
