摘要：
A medical grasping device (1 ) has an elongate control member (9) with a graspingmember ( 17) proximal to its distal tip. An outer sheath (3) with a passageway therethroughsurrounds the elongate control member and is relatively movable with respectto the control member. A control assembly (2) disposed at a proximal end of saidouter sheath has a fixed handle (5) and a sliding handle (7) and the proximal endof the elongate control member is fixed to the sliding handle to move the controlmember. The grasping member (17) has a plurality of pre¬ formed wire loops(50, 52, 54, 56) which self-deploy transversely upon emerging from said distalend of said outer sheath. Each wire loop is fastened to substantially oppositesides of the elongate control member so that each of said wire loops is substantiallysemi-circular upon full deployment and the respective ends (27, 29)of each wireloop extend substantially in opposite directions from the elongate controlmember.
