Research on the Application of Electromagnetic Navigation Technology in Surgical Robots

Due to the need to achieve precise operations during surgery, in order to prevent hand tremors and poor surgical field of view, more and more surgical robots are used in surgical operations combined with navigation technology to meet the requirements for surgical accuracy. Open surgery such as orthopaedics, joint replacement and neurosurgery on the market generally use optical navigation systems to guide robots to achieve precise positioning, but optical navigation systems cannot be used for operations in areas with small surgical space. Therefore, a robotic surgical system based on electromagnetic navigation technology that can be applied to the craniofacial area was proposed. By using this robot, the problems of difficult operation and low precision caused by the narrow craniofacial space can be solved. Key techniques and considerations are studied. The function of the developed prototype is verified through model tests. The test results show that the surgical robot under the electromagnetic navigation technology can achieve precise surgical operations improve the success rate of the doctor's surgery and reduce postoperative complications.
