System design for orthognathic aided robot

In this paper, we study on the cooperation of the virtual digital surgery design technology, three-dimensional navigation and high-precision robot, aiming to implement the preoperative design content more accurately. In this system, virtual digital surgery design acts as the “brain” to provide position and motion information. Three-dimensional navigation system can carry out tasks such as registering coordinates, offering intraoperative navigation, measuring and verification. Besides, because of the advantages in accuracy and stability, high-precision intelligent manipulator UR5 can assist doctors in improving the operating accuracy and quality. This system can implement the virtual digital operation plan in world space to insure that surgery can be operated more accurately and satisfactory. Preliminary experiments for orthognathic surgery have been carried out to analyze the reliability of this system.
