In front of the operating table, the doctor performs a total knee arthroplasty (TKA) assisted by a robot. The display screen of the navigation console clearly shows the three-dimensional model of the patient's knee joint. The osteotomy hand saw is no longer held in the doctor's hand but Installed on a seven-axis medical robotic arm. Surgery like this is coming out of science fiction movies and is being used clinically in 17 hospitals including Peking Union Medical College Hospital and Zhongshan Hospital Affiliated to Fudan University.

my country's self-developed HURWA joint surgical robot has been approved by the National Medical Products Administration (NMPA) and has become the first domestic knee joint surgical robot approved by the NMPA. Behind this, we have completed the transformation from technological innovation to The road to product transformation. "

The project team has gradually grown from a few people to more than 140 people, gathering outstanding talents in medical, software, machinery and other multi-disciplinary fields. Up to now, Hehua Surgery has 57 authorized patents, 89 trademarks, and 34 software copyrights, and has developed intelligent medical equipment that integrates clinical medicine, biomechanics, computer science and other disciplines, filling the domestic market. Gap in the field of robotics for total knee surgery with navigation and osteotomy operations.

"Focusing on clinical needs and solving clinical problems is our original intention. The HURWA joint surgery robot was initiated by a professor of orthopedics at Peking Union Medical College Hospital, and the combination of medicine and engineering has become an instinct carved into the bones of Hehua Surgery. A lot of reliability tests have been done. "We have established cooperative relationships with professional third-party medical testing institutions to conduct tests from bottom-up and top-down dimensions. On the one hand, the equipment is disassembled. The smallest component is a screw. When the team is doing aging tests, fatigue tests, and vibration tests, they will analyze the impact on the overall equipment if the screw is loose or damaged. On the other hand, the module and the whole machine are analyzed and verified, and the team will think about what kind of emergency plan can be provided for doctors when the most extreme situation occurs. In order to simulate and verify the whole machine, they intercepted more than 1000 lamb bones.

There was a 26-year-old girl who suffered from rheumatoid arthritis for 21 years and had severe deformities of both knees. Traditional surgery faces technical difficulties such as difficult exposure, inaccurate anterior and posterior condyle and tibial osteotomy, and large gap between flexion and extension. With the help of the HURWA joint surgery robot, doctors can overcome the corresponding problems through functions such as preoperative planning and intraoperative spatial registration. Now the patient can stand up and walk normally, which also brings hope for more and more patients with complex orthopaedic diseases.
