A new femur distractor for operative leg lengthening has been developed. The new instrument consists of an electronically controllable distractor set including a power unit and a two-part guide rail. The whole system can be implanted totally and gives rigid fixation throughout the period of distraction. The operations "forward motion", "stop" and "backward motion" can be regulated transcutaneously by radio control. A prototype especially developed for animal experiments has been tested successfully in sheep.
一种用于手术肢体延长的新型股骨撑开器已研发出来。这种新器械由一套电子可控撑开器组成，包括一个动力装置和一个两部分组成的导轨。整个系统可以完全植入，并在撑开期间提供牢固的固定。“向前运动”“停止”和“向后运动”等操作可通过无线电控制经皮调节。专门为动物实验开发的一个原型已在绵羊身上成功测试。
