Present body-powered upper-limb prostheses use a cable control system employing World War II aircraft technology to transmit force from the body to the prosthesis for operation. The cable and associated hardware are located outside the prosthesis. Because individuals with arm amputations want prostheses that are natural looking with a smooth, soft outer surface, a design and development project was undertaken to replace the cable system with hydraulics located inside the prosthesis. Three different hydraulic transmission systems were built for evaluation, and other possibilities were explored. Results indicate that a hydraulic force transmission system remains an unmet challenge as a practical replacement for the cable system. The author was unable to develop a hydraulic system that meets the necessary dynamic requirements and is acceptable in size and appearance.
目前的身体驱动上肢假肢使用一种采用二战飞机技术的缆线控制系统，将身体的力量传递到假肢以进行操作。缆线及相关硬件位于假肢外部。由于截肢者希望假肢外观自然，具有光滑、柔软的外表面，因此开展了一个设计与开发项目，用位于假肢内部的液压系统取代缆线系统。构建了三种不同的液压传动系统进行评估，并探索了其他可能性。结果表明，作为缆线系统的实际替代品，液压力传输系统仍是一个未得到解决的挑战。作者未能开发出一种满足必要动态要求且在尺寸和外观上可接受的液压系统。
