计算机辅助设计与制造系统用于大腿假肢远程加工的效果

Application of Computer Aided Design/Computer Aided Manufacturing System for Tele-process of Lower-limb Prosthesis

目的探索使用专业假肢计算机辅助设计软件和制作系统进行远程制作大腿假肢的可行性。方法通过互联网,将异地假肢临床接待室的8例大腿截肢患者残肢尺寸数据传送到计算机假肢制作加工中心,利用软件数据模型库选择相应的大腿假肢接受腔口型圈并按照尺寸表进行数据模型修改,将修改后的数据模型进行实体模型加工并送至假肢临床接待室给患者适配假肢。给患者试穿假肢后按照大腿假肢临床功能评估进行评价。结果 7例患者大腿假肢临床功能评估达到要求。结论通过严谨的残肢尺寸测量并进行计算机设计和远程加工的模式是可行的。该模式可解决偏远地区大腿截肢患者无法制作假肢的问题。

Objective To explore the feasibility of professional computer- aided design prosthetic software and processing systems for tele-process of lower-limb prosthesis. Methods The residual limb size data of 8 leg-amputation patients in prosthetic clinical reception were transferred to the computer prosthetic processing center. The appropriate lower-limb prosthetic socket mouth circles were selected in the software data model library, and were modified in accordance with the size table, and then they were processed and sent to the prosthetic clinical reception for the patients. The clinical function of lower-limb prosthesis was evaluated after try-on. Results The clinical function met the requirements in 7 patients wearing the prosthesis. Conclusion It is possible to design and tele-process lower-limb prosthesis through elaborate dimensional measurement, which can be a mode to serve lower-limb prosthesis to remote areas.
