To allow an amputee resume healthy walking, a well-designed lower limb prosthesis is required. However, in many developing countries, the cost of high-tech and often imported prosthesis is out of the financial reach of many amputees. The objective of this study was to design and implement a mechanical, body-powered transfemoral prosthetic device to help transfemoral amputees regain functional ambulation. The materials used include socket adapter, acetone hardener, plaster of Paris bandages, perlite lining, and polyester resin. Using anthropometric measurements of a volunteer amputee, a user-friendly and ergonomic transfemoral prosthetic device was designed using AutoCAD rendering and fabricated using engineering methods such as casting and welding. The prosthetic limb consists of a polypropylene socket, a galvanised iron knee joint with a hinge and spring suspension system, and a perlite foot. An evaluation of the prosthetic limb after fabrication showed that it restores the ambulatory function of the amputee.
为了让截肢者能够恢复健康的行走，需要设计一款合适的下肢假肢。然而，在许多发展中国家，高科技假肢的成本往往很高，许多截肢者无法负担。本研究的目的是设计和实现一种机械、身体驱动的股骨假肢，帮助股骨截肢者恢复功能性行走。使用的材料包括插座适配器、丙酮硬化剂、熟石膏绷带、珍珠岩衬垫和聚酯树脂。根据志愿者截肢者的人体测量数据，使用 AutoCAD 渲染设计了一款用户友好、符合人体工程学的股骨假肢，并使用铸造和焊接等工程方法进行制造。假肢由聚丙烯插座、带铰链和弹簧悬架系统的镀锌铁膝盖关节以及珍珠岩脚组成。假肢制造完成后的评估表明，它恢复了截肢者的行走功能。
