Embodiment Construction

[0070] The present invention will be further described below in conjunction with the accompanying drawings.

[0071] Such as figure 1 As shown, the design method of the fitting surface of the femoral condyle prosthesis based on the bionic hand structure includes the following steps:

[0072] Step 1: Construct the outline of the bionic finger;

[0073] The bionic hand refers to, as figure 2 Anatomically similar structures of the human hand are shown, including the medial bionic hand and the lateral bionic hand.

[0074] The structures of the inner bionic hand and the outer bionic hand are composed of four finger outlines.

[0075] Such as image 3 As shown, for the inner bionic hand, from the inside to the outside, the finger outlines are: index finger outline (i=1, corresponding to the index finger), middle finger outline (i=2, corresponding to the middle finger), ring finger outline (i=3, corresponding to the ring finger) and the outline of the little finger (i=4, corre...

Abstract

The invention discloses a femoral condyle prosthesis fitting surface design method based on a bionic hand structure. The method comprises the following steps: step 1, constructing a bionic finger contour line; 2, constructing a bionic palm surface; and 3, constructing a femoral condyle prosthesis fitting palm surface. The invention further discloses application of the femoral condyle prosthesis fitting surface design method based on the bionic hand structure in knee joint replacement surgery. A bionic finger structure is constructed by setting key joint points, a femoral condyle prosthesis fitting surface curved surface conforming to the femoral condyle of a human body is set, a bionic palm surface is modified by adjusting palm surface bending parameters and palm surface size parameters, and a femoral condyle fitting palm surface is obtained based on a femoral condyle outer side contour line. The method has the advantages of being simple, flexible, efficient and the like, the bionic hand structure is well attached to the palm face and the femoral condyle, and the knee joint is high in bending degree and good in flexibility.

Description

technical field [0001] The invention relates to a design method and application of a fitting surface of a femoral condyle prosthesis based on a bionic hand structure, and belongs to the technical field of computer-aided analysis. Background technique [0002] The femoral condyle prosthesis is an important part of the knee prosthesis. The design of femoral condyle prosthesis is a key technology in the field of medical devices, and plays a vital role in the treatment effect of knee replacement surgery. Usually, we regard the side of the femoral condyle prosthesis that replaces the native femoral condyle as the fitting surface. The higher the degree of matching between the fitting surface of the femoral condyle prosthesis and the native femoral condyle, the more conducive to rehabilitation, thereby reducing postoperative loosening of the prosthesis and poor blood supply. It can be seen that the design of the fitting surface of the femoral condyle prosthesis is very important....
