摘要
Abstract
Human hip joint has a S-shaped canal,the existing standard straight hip prosthesis matching with the femur cavity of the patient,will form a three-point contact and reduce the fit precision between hip prosthesis and femur cavity.The pig shank CT data is applied to reconstruct the three-dimensional model of femur cavity to as a design model of the prothesis,which is imported into robot simulation software for programming and simulation of grinding,then,the prosthesis model is copied on the copper bar by using robotic grinding technology.After the prosthesis matched with femur cavity,the matching case is detected by X-ray image,and the size error between the prosthesis and femur cavity on the cross-sectional is measured to verify the method of individualized prosthesis design and the feasibility of robot grinding prosthesis.The experimental results show that 90.84％ of the matching area is less than 1 mm when the femur cavity is matched with prosthesis.关键词
