Abstract
A basket type grasping tool of the present invention is equipped with a basket including a plurality of groups of elastic wires. The elastic wires in the respective elastic wire groups have a branch point at the same distance position in an intermediate position from a forward end tip to a rear end tip. Since the elastic wires in the respective elastic wire groups are expanded from the branch point in a spread-apart way, a stable basket shape is maintained, so that a stone can be positively grasped in the basket.
