Application of computer-assisted surgery system in artificial joint surgery / 中国组织工程研究

ABSTRACT

Anatomy, materials science, engineering, bio-mechanics, electrical machinery, remote control and computer technology, etc, have generally reflected the development of modem artificial joint surgery, and computer technology plays a particular role. Computer-assisted surgery system can be manipulated to combine space three-dimensional navigation technology, computer image processing and visualization technology with clinical operations, and to calculate the signal transmission and reception of transmitter location points using computer, So as to work out all kinds of curves and angles, which transform the invisible and virtual human parameters directly into animated images, and at the same time enabling the location of surgical instruments to show real-time updates at intraoperative imaging. This will let the doctor know, at any time, the relationship between the location of surgical instruments and the anatomical structure of patients, thus avoiding the important anatomical structure to ensure a safe operation. It simulates surgical instruments' forward and backward as well. Storage surgery route and measuring the angle, length and diameter of implant will make the operation more convenient for doctors in an objective manner, so as to facilitate surgeries. The prosthesis's location, the angles of slope and rotation, master of power line, and the location of osteotomy all need a precise positioning in the process of artificial joint replacement. With the promotion of computer-guided surgery of joint surgery, artificial joint replacement, with the help of computer navigation surgery, can control error at a distance of 1 mm and angle of 1° so as to ensure the accuracy of the location of prosthesis, match it exactly and strictly, thereby reducing the chance of loosening, wear and osteolysis, extending the life of artificial joints, and providing a better joint function.
