This paper evaluates the accuracy and safety of a long bone fracture reduction robot under different surgical modes.
A long bone fracture reduction robot system was developed, which can be controlled via an autonomous surgical mode or a master-slave surgical mode. Reduction experiments were conducted on a long bone cadaver specimen. The accuracy and safety of the robotic reduction were compared across the different surgical modes.
When the fracture reduction was completed by the robot, the translational deviation was less than 2 mm, and the angular deviation was less than 3° The autonomous reduction time was 140 s, while the master-slave reduction time was 200 s.
Based on CT imaging verification, the accuracy of the robot in both autonomous and master-slave surgical modes meets clinical requirements. Future work will focus on further optimizing the robot system.
本文评估了一种长骨骨折复位机器人在不同手术模式下的准确性和安全性。
开发了一种长骨骨折复位机器人系统，可通过自主手术模式或主从手术模式进行控制。在长骨尸体标本上进行了复位实验。比较了不同手术模式下机器人复位的准确性和安全性。
当机器人完成骨折复位时，平移偏差小于 2mm，角度偏差小于 3°。自主复位时间为 140s，而主从复位时间为 200s。
基于 CT 成像验证，机器人在自主和主从手术模式下的准确性均满足临床要求。未来的工作将集中于进一步优化机器人系统。
