For unilateral below-elbow amputated children a new elbow-controlled hand prosthesis has been developed. Since the triceps of young children have insufficient power to activate normal spring-closing hands, a special mechanism with low operating power has been developed for this prosthesis. A stiff spring gives a good gripping force. When the elbow is slightly extended this spring is switched off, and by further extension the hand is opened against a weak spring. So far, six children have used this special prosthesis. Their initial enthusiasm resulted in an improved system, which is now being designed.
针对单侧肘下截肢儿童，已研发出一种新型肘部控制的假手。由于幼儿的三头肌力量不足以驱动正常的弹簧闭合式假手，因此为这种假手开发了一种操作力量较小的特殊机制。一个硬弹簧可提供良好的抓握力。当肘部稍微伸展时，这个弹簧会断开，进一步伸展时，假手会靠着一个弱弹簧张开。到目前为止，已有六名儿童使用了这种特殊假手。他们最初的热情促使了系统的改进，目前该系统正在设计中。
