Abstract: A treatment device includes a treatment tool and an outer tube connected to a long guide device and into which the tool is inserted, wherein the tube includes: a slack portion formed from a portion of the tube in a longitudinal direction of the tube, the slack portion being disposed in a slackened state; and a movable portion disposed on a proximal-end side of the slack portion, the movable portion being movable forward and backward in the longitudinal direction, and a slack amount of the slack portion changes as a result of the movable portion being moved forward and backward with respect to the tool, and, accordingly, a distal end of the tool disposed farther on a distal-end side than the slack portion is moved in the longitudinal direction.

Abstract: An overtube for an endoscope includes: a tube body having a main lumen through which the endoscope is inserted and an air-supply lumen through which gas flows; a fixing balloon provided on an outer peripheral surface of a distal end of the tube body, expandable outward from the outer peripheral surface and contractible toward the outer peripheral surface; an air supply device configured to send the gas to the air-supply lumen; and an airtight valve unit having a tubular portion communicating with the main lumen at a rear end of the tube body, the airtight valve unit closing the gap between the endoscope inserted through the tubular portion into the main lumen and an inner peripheral surface of the tubular portion.
