Auxiliary robot for total knee joint replacement surgery

Abstract

The invention discloses an auxiliary robot for total knee joint replacement surgery. Two groups of stereo vision and light source mechanical arms with seven joints are designed, and the function of rapid and accurate stereo reconstruction of knee joint surgery is achieved; two mechanical arms with supporting and clamping positioning components are designed, the fixation of thighs and cruses in thetotal knee joint replacement surgery is achieved, and thus knee joints are fixed, and guarantee is provided for the accuracy of the surgery; two mechanical arms for turnover clamping of skin and muscle tissues are designed, and four novel turnover clamping components work together to realize minimally invasive and accurate turnover of skin and muscle tissues of a knee joint incision and reduce secondary trauma of the surgery incision turnover; an surgery mechanical arm with four executive components is designed, the knee joint skin and muscle tissue cutting, incision hemostasis, leg bone cutting, leg bone drilling and other functions for the knee joint replacement surgery are achieved, real-time function switching is achieved, and the accuracy, stability and efficiency of the surgery canbe greatly improved.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to an auxiliary robot for total knee joint replacement surgery. Background technique [0002] With the rapid development of industrial technology, robot technology has developed rapidly, among which robot technology has entered the medical field, bringing new major technological changes to the medical field. In the field of orthopedic surgery, especially total knee replacement surgery, the surgical effect is too dependent on the experience of the surgeon, which undoubtedly increases the instability of the surgical effect. For example, when a doctor cuts joint bones and other steps, both the doctor and the patient will inevitably experience minor problems, such as coughing, fatigue, insufficient positioning accuracy or measurement errors, which make the position of the implanted joint exceed the allowable standard range. , affecting the accuracy of the operation.
