膝上或膝下截肢者的下肢假肢仍然几乎完全以手工方式设计和生产，严重依赖矫形技术人员的经验和手工技能。本文介绍了主要特点的虚拟环境开发，以协助技术人员设计和测试假肢的原型。为了实现用完整的虚拟过程取代手动过程的宏伟目标，已经考虑并解决了几个问题：骨科技术人员的过程知识的捕获和形式化，患者信息和数字数据的获取，设计和测试标准和定制组件的集成解决方案的开发，以及佩戴虚拟假体的虚拟人的步态模拟。假体设计平台的架构以及建模和仿真工具进行了描述。最后，实验阶段和相关的结果进行了介绍和讨论。
Lower limb prostheses for above or below knee amputees are still designed and produced almost completely in a manual way, deeply relying on the experience and manual skills of orthopaedic technicians. This paper presents the main features characterising the prototype of a virtual environment developed to assist the technicians designing and testing the prosthesis. To reach the ambitious goal of replacing the manual process with a complete virtual one several issues have been considered and addressed: the capture and formalisation of process knowledge of orthopaedic technicians, the acquisition of patient's information and digital data, the development of an integrated solution to design and test standard and custom-fit components and the simulation of the gait of a virtual human wearing the virtual prosthesis. The architecture of the prosthesis design platform as well as the modelling and simulation tools are described. Finally, the experimentation phase and related results are presented and discussed.
