Able to perform high-precision minimally invasive surgery, “on duty” in more than 100 medical institutions, and the nails are more tidy than the old doctor… In Beijing, located in Dongsheng International Science Park, Zhongguancun, Haidian District The Medical Robot Industry Innovation Center has a variety of powerful robot “doctors”.
Innovation Center is a shared integration for medical robot companies operating room.
Robot for Fracture Reduction
100% successful pelvic surgery
84-year-old man suffered a pelvic fracture due to a fall. My body can’t bear the traditional open pelvic surgery, what should I do? Family members came to Beijing Jishuitan Hospital for help.
With the assistance of an intelligent fracture reduction robot, the doctor performed closed reduction and internal fixation of pelvic fractures for the elderly. This is a highly difficult minimally invasive surgery, which is difficult for doctors to perform with bare hands. With the assistance of a robot “doctor”, the surgical effect is very good. The old man was able to sit up on the second day after the operation, and the pain was significantly relieved.
It turns out that the robot system will automatically plan the optimal fracture reduction plan through the CT 3D model before surgery. During the operation, the robot accurately and safely completes the automatic reduction of pelvic fractures under the joint action of real-time 3D navigation, force-position coordinated control and other technologies.
According to reports, the intelligent fracture reduction robot is currently the only medical robot in the world that can complete the reduction of complex pelvic fractures. The scientific research and clinical trials of pelvic fracture surgery were conducted in 22 cases, and the success rate of closed reduction was 100%. Compared with traditional surgery, the success rate of closed reduction is increased by more than 5 times. At present, the system has officially entered the multi-center clinical trial stage of product registration.
Traditional surgery requires an incision of 20 cm to 30 cm transversely on the patient, and blood transfusions of 2000 to 3000 ml are required during the operation. At least 1 month of recovery. With the robot “doctor” on the field, only an incision of 2 cm to 3 cm is required, the blood loss is about 100 ml, and the patient can walk on the ground in 3 to 5 days, which greatly shortens the patient’s hospitalization and postoperative recovery time. , reducing the burden of medical expenses on patients.

Even a senior doctor sighs like this
A photo of a doctor’s post-operative Moments , there are two sets of X-ray contrast photos, and the parallelism of the arrangement of the steel pins is significantly higher in the robot-assisted photos. “Experience and feel are completely defeated in front of robots!” the doctor sighed.
As early as 2019, orthopedic surgery robots entered people’s field of vision because of a 5G remote surgery. Tian Wei, the then president of Beijing Jishuitan Hospital, used 5G technology to connect with the Second Hospital of Jiaxing City and Yantai Mountain Hospital of Yantai City through a remote system control platform, and remotely controlled two orthopaedic surgery robots to successfully perform spinal surgery on two patients. .
How do robots help doctors perform surgery? According to reports, the robot played the role of “brain, eye and hand” during the operation. This surgical robot consists of two devices. In layman’s terms, one is the brain and the eye. According to the data collected by computer X-ray (CR), it assists the doctor to plan the surgical plan, locate the treatment site, and the displacement caused by the patient’s breathing can be Precise identification. The other is the arm, which receives instructions from the “brain” to precisely locate the location, angle, and depth of the nails.
“In foreign countries, more than 50% of orthopaedic surgeries assisted by robots have adopted minimally invasive methods.” Experts say that as an orthopaedic surgeon, “Partner”, this orthopedic robot has now been widely used in spine and trauma orthopedic surgery, and has “worked” in more than 100 medical institutions in more than 20 provinces, municipalities and autonomous regions, and performed 10,500 operations in 2021 alone.
In 2021, an orthopedic robotic surgery has been included in the category of Beijing Class A medical insurance payment. With the popularization of technology and the improvement of business models, it is believed that robot-assisted orthopedic surgery will become routine surgery. Experts say the new technology will benefit more patients.
High-precision domestic “arm”
The tip of the cone touches the balloon to ensure that it will not be punctured
In the interview, the reporter learned that the current orthopedic robot It is still being upgraded, and its major breakthrough is that the “arm” will be localized.
In a research and development room, the reporter saw this robot named Diana Med. Compared with other industrial robots in the research and development room, the white Medical robots appear softer.
“It has 7 degrees of freedom. In layman’s terms, there are 7 ‘joints’, which are the same as the number of joints in the human arm. Flexible.” The person in charge Wang Qian told reporters that they started the research and development in the field of medical robots in early 2019. At present, the technical route of medical robot arms has two directions: hard tissues such as orthopedics, dentistry, neurology, etc., and soft tissues such as radiofrequency ablation , Ultrasound infrared diagnosis and treatment, traditional Chinese medicine massage physiotherapy, etc.
“For example, in a medical scene, you can simulate the perception of force and set a safe area. Once it reaches the boundary of the safe area, the robotic arm can Give the doctor a reverse force to avoid ‘crossing the border’.” Wang Qian said, “Diana Med’s force sensing sensitivity is 0.5 Newtons and the positioning accuracy is 0.02 mm.”
< p>Medical robot arm toHow flexible is it? In the collision test, the front end of the robot arm “held” a steel cone, and the staff held the balloon and stopped on the travel route of the robot arm. When the tip of the cone touched the balloon, it immediately stopped and retracted, and the balloon did not rupture.
Frontier Interviews
< strong>Market focus is shifting from North America to Asia
Li Qi, Deputy General Manager of Beijing Medical Robot Industry Innovation Center According to the introduction, the global market size of medical robots in 2020 will reach 8.307 billion US dollars, and it is still developing rapidly. The market focus of medical robots is gradually shifting from North America to Asia, and the growth rate of the Asia-Pacific region is significantly higher than that of other regions. The medical robot industry has the characteristics of high threshold, large investment, long cycle and strict supervision, but medical robots are also one of the few fields in my country with international original technological achievements and world-leading products.
At present, the Beijing Medical Robot Industry Innovation Center has built six advanced technologies, common technologies, product design, prototype manufacturing, testing and evaluation, and clinical research. Great Center. In July last year, the “Two Districts” construction key project in Haidian District and the Zhongguancun National Independent Innovation Demonstration Project – the high-end medical device CDMO (Contract R&D and Manufacturing Organization) platform was also officially put into production, allowing more high-end innovative products from concept, prototype to The products are listed to achieve low-cost and efficient transformation, and help the high-quality development of Beijing’s high-end medical equipment industry.
