Abstract: A scanning endoscope includes: an optical fiber that guides illuminating light and emits the illuminating light from a distal end; an actuator for swinging a distal end of the optical fiber; a first tubular member that encloses a distal end of the optical fiber and the actuator; a holding portion that holds the optical fiber so that a distal end of the optical fiber is swung by the actuator; a second tubular member that encloses the first tubular member; a fixing portion that is disposed in an area perpendicular to a longitudinal direction of the optical fiber, the area being aligned with a position where the holding portion is disposed, and fixes the first tubular member to the second tubular member; and a distal end fixing portion that is provided at a distal end of the first tubular member.

Abstract: A treatment tool includes: a tubular portion including a tubular portion main body having a long tubular shape and an opening section provided in the tubular portion main body, the tubular portion being configured to suck a tissue piece from the opening section; a blade portion provided in a part of an opening edge in the opening section; and a non-blade portion provided in at least a part other than a region where the blade portion is provided in the opening edge, the non-blade portion being configured to slide the tissue piece. The blade portion includes an edge having a smallest sectional area in a cross section of the blade portion taken along a plane including a central axis of the tubular portion main body, and only the edge is located on an imaginary plane obtained by extending an opening surface of the opening section.
