| 摘 要： | 背景:全髋关节表面置换在进行假体装配中,需要与实体绝对匹配的3D模型。目的:通过逆向工程/逆向设计技术三维重建金属对金属全髋表面置换假体。方法:基于三维激光扫描仪所得假体的点云文件,Geomagic软件和3dsmax软件再分别进行点云拼接、3D还原、特征提取从而得到全髋表面置换假体的三维可视化结构。结果与结论:逆向工程/正向设计技术能还原假体的三维形态,可真实再现髋臼假体和股骨假体的结构。提示根据逆向工程/正向设计软件系统能准确重建金属对金属全髋表面置换假体。 |

| Abstract: | BACKGROUND: During the prosthesis assembly, an absolutely matched three-dimensional model is required. OBJECTIVE: Through the exploration of reverse engineering/forward design technique to find a fast and accurate method for reconstruction of a three-dimensional model of hip surface replacement prosthesis. METHODS: Based on point cloud file from the three-dimensional laser scanner, proximal femur component, acetabular component were reconstructed by the Geomagic and 3ds max software. RESULTS AND CONCLUSION:... |
