<P>PROBLEM TO BE SOLVED: To provide a therapeutic instrument for capturing foreign matters inside a body cavity, capable of effectively capturing the foreign matters, and coming into effective tight contact with a body cavity inner wall. <P>SOLUTION: This therapeutic instrument 10 includes: a tubular sheath 20; a support shaft 30 slidably disposed inside the sheath; and a capture member 40 for capturing the foreign matters inside the body cavity, attached to the tip of the support shaft 30 and retractable from the tip of the sheath 20. The capture member 40 has a plurality of wires 41 made of a hyperelastic alloy, each having a base end part 41a fixed to the support shaft 30 and a tip part 41d bound to each other. The wires 41 have such a shape that the wires are extended from the tip of the support shaft 30, are bent to the base end direction of the support shaft 30 outward to radially expand outward, and thereafter are bent again to the tip direction of the support shaft 30, and the tip parts of the wires are bound together. <P>COPYRIGHT: (C)2012,JPO&INPIT |
