Many transtibial amputees rate the fit between their residual limb and prosthetic socket as the most critical factor in satisfaction with using their prosthesis. This study aims to address the issue of prosthetic socket fit by reconfiguring the socket shape at the interface of the residual limb and socket. The proposed reconfigurable socket shifts pressure from sensitive areas and compensates for residual limb volume fluctuations, the most important factors in determining a good socket fit. Computed tomography scan images are employed to create the phantom limb of an amputee and to manufacture the reconfigurable socket. The performance of the reconfigurable socket was evaluated both experimentally and numerically using finite element modelling. The study showed that the reconfigurable socket can reduce interface pressure at targeted areas by up to 61%.

用于小腿截肢者的气动可重构插座

许多经胫骨截肢者将残肢与假肢接受腔之间的配合视为对使用假肢是否满意的最关键因素。本研究旨在通过重新配置残肢和接受腔界面处的接受腔形状来解决假肢接受腔的贴合问题。所提出的可重构接受腔可转移敏感区域的压力并补偿残肢体积波动，这是决定接受腔良好贴合的最重要因素。利用计算机断层扫描图像来创建截肢者的幻肢并制造可重构的接受腔。使用有限元建模对可重构插座的性能进行了实验和数值评估。研究表明，可重构插座可以将目标区域的界面压力降低高达 61%。
