Abstract:Objective The purpose of this study is to design a robotic system which integrates the robot technology and the optical
navigation technology to solve the problems in the present orthopedic surgery. Methods Through the principle analysis, system
design and manufacture, the optical navigation guided surgical robot system was completed. A special device of accuracy test was
designed to validat the accuracy of the system. Then some clinical trials were conducted to verify the clinical safety and efficacy
of the system. Results The positioning error of the operation robot system guided by optical navigation was less than 1.0 mm. The
clinical trial showed that the insertion error of the robot assisted spinal pedicle screw surgery was significantly less than that of the
conventional free hand method. Conclusion The surgical robot system with “hand-eye” is able to realize the precise location of
operation path in orthopedic surgery.
