    • According to an embodiment of the present disclosure, a retrieval device may include a distally located end effector movable between a contracted state and an expanded state. The end effector may include a plurality of support members each including a passage. The end effector may also include a plurality of movable members. A first movable member may include a first portion extending into a first passage of the support member passages. The retrieval device may also include a proximally located handle assembly including a longitudinal actuator and a twisting actuator coupled to the plurality of movable members. The longitudinal actuator and twisting actuator may be configured to longitudinally move and twist the movable members without longitudinally moving and twisting the support members.
    • 根据本公开的实施例,取出装置(10)可以包括可在收缩状态和扩张状态之间移动的位于远侧的末端执行器(50)。 末端执行器(50)可以包括多个支撑构件(26,28,30),每个支撑构件包括通道。 末端执行器(50)也可以包括多个可移动构件(18,20,22)。 第一可移动构件(18)可以包括延伸到支撑构件通道的第一通道中的第一部分。 取回装置(50)还可以包括位于近侧的手柄组件(200),该手柄组件包括纵向致动器(16)和联接到多个可移动构件(18,20,22)的扭转致动器(16)。 纵向致动器16和扭转致动器16可以构造成纵向移动和扭转可动构件18,20,22而不纵向移动和扭转支撑构件26,28,30。
