摘　　要：提出了一种新型的医用微型机器人的驱动机构 ,设计建造了模拟实验台。它利用螺旋旋转时产生的轴向牵引力推动机器人在人体内腔中运行 ,同时利用螺旋旋转时产生的动压效应建立起动压润滑粘液膜 ,使机器人在体内运行时不与内腔壁发生直接接触 ,避免对人体有机组织的损伤。实验研究结果表明 :此种医用微型机器人在管内运行时可以形成足够厚的粘液膜把机器人与管壁隔开 。A new kind of medical micro robot impeller is introduced and a test machine is designed and constructed This kind of the micro robot moves in endocoeles with axial traction force which is produced by rotating spiral The hydrodynamic mucus film is formed with hydrodynamic effect which is produced by rotating spiral, so this micro robot doesnt contact directly endocoele tubes and avoids injury to organic tissues The experimental study results indicate that the hydrodynamic mucus film formed during the micro robot motion in endocoeles is thick enough to separate the micro robot form endocoele tubes and the micro robot can be suspended to move quickly
