The orthopedic robot is coming! It is easier to replace the artificial joint.

The orthopedic robot is coming! It is easier to replace the artificial joint.

The artificial knee replacement in Taiwan Province Province is in step with the world. About two years ago, robotic arms were used to replace artificial knees. The mechanical arm is equivalent to the orthopedic surgeon's third eye and hand. With its assistance, the accuracy of artificial semi-knee joint surgery is improved, the trauma is less and the recovery is faster. Most patients can walk home on the day of operation or the next day, or even go to work directly after discharge, which saves postoperative recovery time and meets a better quality of life, representing the arrival of a new era of minimally invasive, accurate, dynamic, three-dimensional and quantitative orthopedic surgery.

Accurate implementation of navigation in minimally invasive surgery.

According to the research, the failure rate of manipulator surgery can be reduced to110 of traditional surgery, and the accuracy is improved by 3-4 times. Xu Hongchang, director of the Department of Orthopaedics, China Affiliated Medical University, said that before the robotic arm operation, the affected side should be scanned by three-dimensional computed tomography (from hip joint to ankle joint), and then input into the robotic arm for preoperative planning and intraoperative execution. Doctors can interact with the computer of the mechanical arm visually and tactilely during the operation, and adjust its static or dynamic ideal position at any time to improve the accuracy of the operation.

The appearance of mechanical arm opened a new page in orthopedic surgery.

Director Xu Hongchang pointed out that robotic arm surgery is also superior to computer navigation surgery. Computer navigation surgery can only guide you how to do it, but it is uncontrollable in "execution", so there may still be "exceptions". The mechanical arm is different, because with the help of vision and touch, it can ensure the execution surface is more accurate, just as car navigation can guide you from place A to place B, but it can't help you drive safely and accurately (execution surface).

According to statistics, there are more than 380 mechanical arm machines in 15 countries around the world, and more than 65438+ 10,000 people have received this kind of surgery. This technique has been able to perform total hip and total knee replacement.

This is not a dream! There is no feeling of cutting after operation.

Xu Hongchang said that the replacement of knee joint by mechanical arm has less injury and less scar tissue, which can preserve the original knee joint of the patient. Patients often don't feel that they have had surgery, and their daily activities or sports are similar. Different from the traditional total knee replacement, they need to "learn" and "adapt" again, and even "change" the original kinematics, so they generally get high satisfaction from patients.

The study also shows that the use of precision technology for medial artificial knee replacement will also improve the stability of patellofemoral joint and reduce the degree of further deterioration; Accurate replacement of lateral artificial knee joint can also improve the stability of medial femur and tibia and joint space. In addition, the accurate placement of artificial semi-knee joint can slow down the phenomenon that one part causes other degenerative arthritis of bone and joint, and avoid the disease from falling into a vicious circle.
