Study on a Medical Robot for Mandible Reconstruction Surgery

The clinical treatment for jaw defects in MRS (Mandible Reconstruction Surgery) including bone grafts, distraction osteogenesis and bone tissue engineering, however, the mandible reconstruction surgery is operated by doctors without 3D navigation at present which leads to lots of disadvantages such as bad operational control, low positioning accuracy and poor stability. Therefore a robotic surgical system was designed to assist surgeons on manipulating. In this paper, the robot system was given in brief, then image processing were introduced in detail on the basis of process analysis of MRS. Four experiments were done to measure the performance of robotic system, and experiment results show that the robot works stably and accurately. The development of this medical robot system contributes to the promotion and popularization of the MRS in clinics.
