Chinanews.com, Lanzhou, March 30 (Yan Jiao) "We innovatively use the'Tianji' orthopedic robot to be accurately planned by the computer navigation system during the operation, the mechanical arm'points and hits which', and can automatically correct deviations at any time. Advantages, it effectively solves the problem of limited knee flexion caused by the large deviation in the selection of reconstruction points in the previous surgery, and avoids the shortcomings of patients and surgeons receiving a lot of'X-ray' radiation due to repeated C-arm fluoroscopy in traditional surgery." Said Xia Yayi, Director of Orthopedics Department of the Second Hospital of Lanzhou University.
Xia Yayi said that the above advantages can effectively prevent damage to the epiphysis and affect bone growth for young patients who have not yet closed the epiphyseal line. The surgical incision is minimally invasive and rapid recovery can be achieved after the operation.
He found that the knee flexion and extension function of the 18 patients who underwent the operation was good, and the patella of the affected knee did not re-dislocate.
Since the installation of the "Dimensity" orthopedic robot in the hospital in 2019, the Department of Orthopedics has completed more than 80 complicated operations of trauma and spine with the assistance of robots. Its advantages in precision and minimally invasive surgery in the field of trauma orthopedics and spine surgery have become increasingly prominent. However, the application of "Dimensity" orthopedic robots in the field of sports medicine is still in the exploratory stage in China.
Xia Yayi said that on the basis of a detailed understanding of the existing assisted surgical procedures of the "Dimensity" orthopedic robot, his team used the advantages of the "Dimensity" orthopedic robot for millimeter-level precision positioning to try and explore the use of "Dimensity" orthopedics Robot-assisted reconstruction of the medial patellofemoral ligament surgery to treat patellar dislocation.
Under his guidance, the team took the lead in completing the first domestic patella-femoral ligament reconstruction operation under the assistance of a “Dimensity” orthopedic robot. After nearly 11 months of continuous optimization and improvement of surgical techniques and procedures, the operation time has now gone from the first 2.5 hours. Reduced to 1 hour.
As the only national-level orthopedic surgical robot demonstration center in Gansu Province, the department has successfully completed 20 cases (two cases are bilateral) of the “Denji” orthopedic robot-assisted reconstruction of the medial patella femoral ligament for the treatment of patellar dislocation. This technology It is in a leading position in the domestic sports medicine field.
In recent years, the hospital has entered a new era of digital intelligence. The orthopedic hardware facilities have been greatly improved, the talent echelon has been well established, and various new diagnosis and treatment technologies have developed rapidly. "Tianji" orthopedic robot-assisted surgery has made great efforts in the fields of spine surgery, trauma orthopedics, and sports medicine. It has already accumulated a wealth of experience.
