【摘要】 提出了一种结构简单的医用微型机器人的驱动机构 ;此种医用微型机器人能够在人体内腔中运行 ,同时利用动压效应在其周围建立起动压润滑粘液膜 ,使机器人在人体内运行时不与内腔壁发生直接接触 ,避免了对人体有机组织的损伤。医用机器人的驱动机构可采用矩形或锯齿形圆柱螺旋。详细分析计算并对比了两种螺旋下其运动特性参数的优劣 ,并优化设计了医用机器人的各结构参数更多还原

【Abstract】 A simple impeller of medical mico-robot was introduced. This micro-robot can move in endocoeles,can prevent the direct contact between this mico-robot and endocoele tube and avoids injury to organic tissues with the hydrodynamic mucus film formed by hydrodynamic effect.The rectangular or serrate screw can be used by the impeller,and the merit and demerit of the motion parameter of this two screws were analyzed and compared. It is propitious to optimize the configuration parameter of the medical micro-robot.更多还原
