人工假肢膝关节微电脑控制装置的研究

THE RESEARCH OF THE DEVICE CONTROLLED BY MICRO COMPUTER ABOUT THE JOINTS OF ARTIF ICIAL LIMB

高位截肢的伤残病人，即使安装了人工假肢，也因为人工假肢的关节不能自由活动，因而行走起来很吃力，动作不协调，姿态不美观。如果在人工假肢的关节处安装一个步进电机，采用微电脑控制技术，使步进电机按照人的意志转动，那么人在行走（或奔跑、弹跳、上下楼梯、下蹬起立等）时，假肢的逼真程度将会大大提高，动作也就十分自然。本文就这种构想谈了制作过程。

Even if a patient whose leg or thigh has been amputated puts on an artificial limb,because the joint of the artificial limb cannot move freely,it is difficult for him to walk briskly,the movement of the artificial limb is out of accordance with that of the body ,and the walKing posture is awkward.If a stepmotor is mounted on the joint of the artificial limb,whick is controlled by a microprocessor to run according to the patient′s will.It will highly improve the flexibility of artificial limb and make him look natural when he is walking(running,jumping,going upstairs or downstairs,squatting down,standing up and so on).This paper describes the procedure to realize this idea.
