Many patients will have concerns about the safety of surgical robots. According to media reports, in February 2015, the first robot heart valve repair surgery in the United Kingdom splashed blood, and finally failed. The results of the later hearing survey showed that the more reason behind the tragedy was that the surgeon was not fully prepared for the operation and did not fully master how to operate the machine. However, the two medical robot experts who should be at the scene failed to appear at the time of the accident, resulting in the master knife inability. Get effective help. Regarding the safety considerations and design of the "Tianyu" orthopedic surgical robot, Dr. Xu Jin said, "Based on the awe of life, we have a complete research and development system." When the orthopedic surgery robot was set up, it had put safety first. At present, the positioning of the orthopedic surgery robot of Tianyi is to assist doctors in auxiliary work. All surgical decisions on the scene are controlled by doctors. The operation of each key step of the robot is also reviewed and approved by a doctor. At the beginning of the design, the product has fully considered the possible emergencies in various links, including ensuring that there is no major medical accidents in the event of power outages or core component failure. At the same time, in order to ensure the standardized operation of doctors, a three-day mandatory training has also been set up to ensure that doctors can operate accurately in all links. On this basis, when the doctor returns to the hospital to carry out the operation, there will also be special clinical engineers and experts to guide the follow-up surgery, and the number of follow-up operations will be guaranteed to be at least 30-50 until the doctor fully masters the operation points of the "Tianyi" orthopedic surgery robot.
