PROBLEM TO BE SOLVED: To provide a foreign object capturing tool for body cavity.SOLUTION: A foreign object capturing tool 10 for body cavity includes: a tube 20; a center wire 30; a first stopper 31 fastened to the outer periphery of the center wire; a second stopper 32 slidably disposed on the outer periphery of the center wire; a plurality of bone wires 40 having a base end part 41 fastened to the first stopper 31 and a tip part 42 fastened to the second stopper 32; and a filter 50 covered from an enlarged diameter part 45 of the bone wire 40 to the second stopper 32 so as to cover the gap between the bone wires 40 and having an aperture at the base end side. Seen from the axial direction of the center wire 30, when a circle centering around the center wire 30 is drawn, the foreign object capturing tool 10 is fastened to the first stopper 31 so that the bone wire 40 inclines in the same direction with respect to a tangent line that crosses an intersection between the base end part 41 of the bone wire and the circle. |
