This orthopedic robot is called "Tianji" and is involved in system research and development by a number of universities and units including Chengdu University.
On May 24th, the “Orthopaedic Robot†was operated by a doctor at the Affiliated Hospital of Chengdu University.
The patient lies on the operating bed, the X-ray film accurately locates the surgical path, and the orthopedic robot cuts a small incision 1 cm long. The precise movement of the mechanical arm is used to create the guide needle placement path. Finally, the doctor accurately inserts the cannulated nail, one The operation of the pelvic fracture was completed... On May 24, the first orthopaedic robot in Chengdu successfully completed an operation. This is the third operation performed by Chengdu University Hospital with the first orthopaedic robot in Chengdu.
This orthopedic robot is called "Tianji" and is involved in system research and development by a number of universities and units including Chengdu University. Because the incision is small, the operation is fast, and the bleeding is less. Compared with ordinary surgery, orthopedic robots are cheaper to operate. "Taking today's surgery as an example, if you perform ordinary surgery, it costs about 50,000 yuan, and with orthopedic robots, the total cost of surgery is more than 10,000."
What is the level? Currently the world leader
According to Professor Li Kainan, who is responsible for the development of orthopaedic robots, orthopedic robots provide orthopedic surgery services for patients, mainly for the use of intramedullary nails for distal locking nail positioning, hip fractures, pelvic fractures, spinal pedicle screw positioning nails, etc. Orthopaedic robots are still in the process of continuous improvement and research and development. "At present, its main value is reflected in the treatment of cannulated nail fixation, which has broad application prospects."
It is reported that Chengdu will be promoted in various hospitals after the first introduction of “Orthopedic Robotâ€. Professor Li Kainan said that the internationally mature Da Vinci medical robot is mainly used for abdominal surgery. A medical robot in the United States mainly performs spinal fixation. The performance of orthopedic robots in orthopedic surgery is at the leading level in the world. A number of national patents.
Chengdu's participation in research and development is the biggest difficulty in precise positioning
This robot is involved in system research and development by a number of universities and units including Chengdu University. Professor Li Kainan is one of the main developers of robots. It took a total of four years from the initial idea to the final completion of research and development.
The research and development of orthopedic robots is not always smooth. Professor Li Kainan told reporters that there have been many difficulties during the research and development period. He believes that the biggest difficulty lies in the precise positioning. Previously, orthopedic robots were operated and tested on the skeletal model, but for clinical use, the accuracy could not be biased, and the error should be controlled within 1 mm. However, after the fracture, it will be different from the normal bone. In order to overcome the accuracy problem, it took a total of three or four years to explore and overcome. At present, more functions of the orthopedic robot are still in the process of improvement.
