Endoscopic treatment tool
First Claim
1. An endoscopic treatment tool comprising:
- a flexible sheath that is to be passed into or out of a treatment tool insertion channel in an endoscope and which has openings respectively formed at and near a distal end of the flexible sheath to communicate with an interior of said flexible sheath; and
at least two manipulating wires that have treating members coupled to distal ends of said at least two manipulating wires, respectively, and which are passed through said flexible sheath such that they can be moved back and forth along the longitudinal axis independently of each other, one of said treating members being provided to have access to said flexible sheath via said opening at its distal end and the other of said treating members being provided to have access to said flexible sheath via said opening near its distal end.

Abstract
An endoscopic treatment tool including a flexible sheath (1) that is to be passed into or out of a treatment tool insertion channel in an endoscope and which has openings (4A, 4B) formed at and near the distal end to communicate with the interior of the flexible sheath (1). A plurality of manipulating wires (3A, 3B) that have treating members (5A, 5B) are coupled to the distal ends and are passed through the flexible sheath (1) such that they can be moved back and forth independently of each other along the longitudinal axis. The treating member (5a) is provided to have access to the flexible sheath (1) via the opening (4A) at its distal end and the other treating member (5B) is provided to have access to the flexible sheath (1) via the opening (4b) near its distal end.

13. An endoscopic treatment tool adapted to be passed into or out of a treatment tool insertion channel in an endoscope, said treatment tool comprising:
-
an elongated flexible sheath defining a longitudinal axis and having first and second openings located offset from each other along said longitudinal axis; a snare loop protruded from said first opening; a foreign matter retaining member protruded from said second opening; a control section provided to said flexible sheath and located opposite from said first and second openings along said longitudinal axis; and first and second manipulating wires operatively connecting said snare loop and said foreign matter retaining member to said control section. - View Dependent Claims (14, 15, 16, 17)
