Navigation method for mandible reconstruction surgery robot

Mandible reconstruction surgery is an extremely complex and high-risk surgical surgery. The aim of the project is to import the robotics technology into mandible reconstruction surgery, which can reduce the workload for doctors, decrease the difficulty of operation and improve the accuracy and quality of surgery. The development of Mandible Reconstruction Surgery Robotic System (MRSRS) provides a solution by integrating pre-operative 3D reconstruction and surgery design, optical navigation system, and intro-operative robot-assisted operation. In this paper, the whole robotic system was introduced firstly. Secondly, a novel Mandible Reconstruction Surgery Multi-arm Robot (MRSMR) and its optical navigation system were developed to assist surgeons. The navigation method of MRSMR was highlighted. At last, the accuracy test of the medical robot was conducted. The skull model experiment is finished to evaluate the robotic system.
