On June 9, the first domestic hip knee compatible robot assisted total knee arthroplasty was successfully completed. The operation was led by Professor Wang kunzheng, President of Shaanxi bone and joint society, chairman designate of the branch of orthopedics of the Chinese Medical Association, director of the joint surgery center of Xi'an Jiaotong University, assisted by Yang Pei, chief physician, Wang Chunsheng, deputy chief physician and Tian Run, associate researcher of the second Affiliated Hospital of Xi'an Jiaotong University.
In 2020, more than 900000 joint replacement operations were completed in China, and the annual growth rate is still about 20%. With the development of population aging, the incidence rate of osteoarthritis and joint replacement surgery is increasing. Due to the relative lack of medical resources and the expanding demand for accurate medical treatment, joint surgery robots have played an increasingly important role in joint replacement.
The hip knee compatible seven axis cooperative robot "artrobot" used in this operation has broken the monopoly of foreign brands in the field of joint surgery robots. The robot is a domestic surgical robot with completely independent intellectual property rights, which is developed by doctors and engineering teams. On the basis of nearly 100 clinical experimental operations of robot assisted hip arthroplasty, the robot assisted total knee arthroplasty is carried out.
Professor Wang kunzheng said after the operation that the "artrobot" robot used in the operation is the first seven axis hip knee compatible operation robot developed by the Chinese team of doctors and workers. During the operation, it can evaluate the range of motion of the knee joint, the alignment of the lower limbs and the joint clearance in real time, and adjust the planning scheme in real time according to the actual situation during the operation, The osteotomy of femur and tibia was accurately completed according to the plan, and the error was controlled within 1mm and 1 ? To achieve personalized and accurate surgical treatment of knee joint within the scope of.
For the breakthrough of this operation, Wang kunzheng also said that this hip knee compatible surgical robot for total knee arthroplasty has greatly improved the clinical pain points with long learning curve and poor accuracy of joint arthroplasty. The development of joint surgery robot has promoted the progress of the whole field of joint surgery. It is hoped that more doctors, enterprises and scientific researchers will participate in the research of new orthopaedic technologies and inject new blood into the development of orthopaedics.
It is understood that the "artrobot" robot used in the operation is independently developed by Hangzhou Jianjia robot company.
In this regard, Xu Jing, founder of Jianjia robot, said, "in recent years, international orthopedic instrument giants have made great efforts to layout the field of surgical robots, and the future trend has emerged. The products of Jianjia robot are not simply domestic and imported substitutes, but the in-depth combination of clinical actual needs and technical upgrading iteration, so as to realize the real domestic innovation. "
When talking about future planning, Xu Jing said that in the future, Jianjia will accelerate the clinical trial and R & D process of orthopaedic surgical robot, become the intelligent surgical housekeeper of orthopaedic doctors and benefit the majority of patients; It will also further strengthen cooperation with medical institutions and scientific research institutions, explore the application and technical breakthrough of new technologies such as robots and artificial intelligence in the medical field, and help doctors solve more clinical difficulties and pain points.
Jianjia robot company was founded in 2018 and was selected into the list of quasi unicorns in Hangzhou in 2021. It focuses on the research and development of orthopaedic surgical robots. It is established by many experts with many years of experience in robot industry, R & D and use. The technical team members graduated from Tsinghua University, Shanghai Jiaotong University, Fudan University, Zhejiang University, MIT in the United States, UCL in the United Kingdom and other well-known institutes at home and abroad. The team covers algorithm research and development, mechanical design, medical engineering combination and other fields, and is at the international advanced level in the key technologies of robot, such as calibration, registration, force control and so on.
