Abstract
PurposeThis paper evaluates the accuracy and safety of a long bone fracture reduction robot under different surgical modes. MethodsA 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. ResultsWhen 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. ConclusionsBased 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.
