A new femur distractor has been developed, lengthening the leg. This instrument is electronically controllable and can be implanted totally. It is possible to regulate transcutaneously by radio control the operation "forward motion", "stop" and "backward motion". After testing this instrument in sheep, the lengthening of human femur by this system can be introduced.
一种新型股骨撑开器已研制出来,可用于延长腿部。该器械由电子控制,可完全植入体内。通过无线电控制可经皮调节“向前移动”“停止”和“向后移动”等操作。在绵羊身上对该器械进行测试后,便可将此系统用于人类股骨延长。
