Zunyi City introduces surgical robot for the first time and successfully performs total knee replacement

With the assistance of experts from Beijing Jishuitan Hospital, the team of Han Xiaosong, a joint surgery expert at Zunyi First People's Hospital, successfully performed the city's first Tianji knee surgery robot-assisted total knee replacement. This is also the first official clinical operation after the Tianji knee surgery robot was approved. The hospital has achieved intelligence and precision in the fields of spine, trauma and joint replacement orthopedics

It is understood that this hospital is the only hospital in the province that has implemented robot-assisted surgery in three fields

According to reports, this patient is 63 years old. His knee joint pain has lasted for a long time, and his symptoms have recently worsened, causing him to be unable to walk normally, seriously affecting his quality of life. On admission, he was diagnosed with left knee arthritis. After detailed consultation and discussion with Director Yang Dejin and Director Wang Liwei of the Monday New Team of the Orthopedic Surgery Department of Beijing Jishuitan Hospital, the joint surgery team decided to perform a robot-assisted total knee replacement surgery for the patient. Through a precise and personalized surgical plan, the joint surgery team decided to joint pain and improve joint function

Before surgery, by conducting CT scans and reconstructing a three-dimensional bone model, we formulated a surgical plan based on the patient's anatomy and lesions, and clarified the location of the osteotomy, the size of the prosthesis required, and the prosthesis. Important information such as the effects required for installation

During the operation, the bone of the surgical limb is first registered and intelligently matched with the three-dimensional bone model. Doctors can use the robotic system to assess the flexion-extension gap balance of the knee joint before osteotomy and make adjustments and modifications to the preoperative plan, which in the past could only be done by relying on the doctor's experience and judgment. It is worth mentioning that the Tianji knee surgery robot can not only evaluate the flexion and extension gap of the knee joint in a static state, but also collect and obtain gap data of the joint during continuous dynamic motion, thereby helping doctors to evaluate more comprehensively and reduce Irreversible damage caused by intraoperative soft tissue release

With the auxiliary guidance of Tianji knee surgery robot, the osteotomy process is more in line with doctors’ traditional surgical habits, while achieving perfect and accurate implementation of the intraoperative plan. During the osteotomy process, there is no need to use a four-in-one osteotomy plate instrument, and damage to the medullary cavity caused by the marrow opening operation is also avoided. Through the combination of man and machine, osteotomy and prosthesis installation can be completed in one go. After the evaluation after the prosthesis installation, the subject's flexion and extension of the surgical limbs were balanced between the medial and lateral gaps, and the knee joint alignment did not exceed 1° of varus. The surgical results were very satisfactory. This time, the robot-assisted knee replacement surgery is more precise and intelligent, with less trauma, less pain for the patient, and faster recovery after surgery

Vice President Han Xiaosong said that after adding robots, the surgical process will be smoother, the safety, predictability and accuracy of the surgery will be improved, and it will have a positive impact on the early and rapid recovery of patients and long-term surgical results. As an important assistant in this operation, the Tianji knee surgery robot is a new generation of surgical auxiliary robot independently developed in China, which continues its high efficiency and accuracy. Through intelligent customized solutions, dynamic assessment and real-time adjustment, precise osteotomy and prosthesis placement, Tianji knee robot can assist doctors in completing precise and personalized artificial joint replacement surgeries, benefiting more patients
