Abstract
BACKGROUND:It is difficult to adjust the anteversion angle of cementless hip joint. Some areas rely on the intraoperative three-dimensional navigation technique to ensure the accuracy of the anteversion angle, but its high cost limits the promotion prospects. OBJECTIVE:To design a kind of artificial femur head, which has special functions to freely adjust the anteversion angle of artificial femur head during operation and lock prosthesis handle to prevent femur prosthesis dislocation and looseness, and to intuitively display the special design concept of this kind of artificial femur head through the three-dimensional dynamic image aided by computer. METHODS:According to the design idea, AutoCAD software was used to get the design drawings for artificial femur head. The three-dimensional modeling was performed by 3DMax software in order to observe the form and degrees of verisimilitude of model. RESULTS AND CONCLUSION:The AutoCAD software was used to draw out the design drawings of artificial femur head according to the design requirements and design idea:the prosthesis handle had three lock hole channel and its basal part was for scale, and rotating the scale could change the anteversion angle of prosthesis neck;the shape of the prosthesis neck was dentate cylindrical. The 3DMax software was used to build the three-dimensional model of the artificial femur head, and the design, form and degrees of verisimilitude of the model comply with the design requirements. The whole structure of the three-dimensional model of artificial femur head is clear and the design is reasonable, which can provide a theoretical reference for further design of artificial femur head.关键词
