| 摘要： |
| 目的：建立小腿假肢接受腔-残肢生物机械系统三维几何模型。方法：以一名25岁男性小腿截肢患者为对象，采用三维坐标测量和核磁共振成像获得原始数据，利用软件MIMICS、SURFACER、SOLIDWORKS等实现了接受腔和残肢的三维重构．并根据接受腔修型模式等完成了系统装配。结果：数字化三维模型较精确的反映了接受腔-残肢系统的几何特征。结论：这种低成本方法可用于假肢数字化设计、有限元分析和计算机辅助制造。 |

| Abstract: |
| Objective:To reconstruct a three-dimensional model of bio-mechanical system in a prosthetic socket of below-knee residual limb.Method:A subject living with below-knee prosthetic socket for 5 years was recruited,and the original data of the stump was obtained through 3-D measuring and MRI.Three-dimensional models of the prosthetic socket and residual limb were reconstructed separately by software MIMICS,SURFACER and SOLIDWORKS etc,and the system was assembled corresponding to rectification template.Result:The new digital 3-D model successfully reconstructed the socket-limb system with high degree of accuracy.Conclusion:This technique with low cost was proved to be available for prosthetic socket designing,finite-element analysis and computer-aided manufacturing. |
| Keywords:prosthetic socket stump three-dimensional reconstruction |
