Abstract: An ablation system includes: an endoscope; an ablation treatment tool; an overtube; a first operation member that is provided at a base end portion of the overtube; and a second operation member that is attachable to and detachable from an intermediate position in a longitudinal direction of an insertion portion of the endoscope. The overtube has a balloon that is configured to fix the overtube to the gastro-intestinal tract; the insertion portion and the ablation treatment tool can be integrally moved in the overtube in the longitudinal direction; and the first and second operation members each have a finger holder that holds at least one finger of one hand. The first operation member is distinct from the overtube, and is attachable to and detachable from an outer circumferential surface of the overtube, at an arbitrary position in the longitudinal direction of the overtube.

Abstract: An optical measuring device includes: a light source unit; a measurement probe including a fiber bundle, an illumination fiber that illuminates a living tissue with a illumination light, and a plurality of light-receiving fibers that receives return light of the illumination light reflected and/or scattered at the living tissue; a detection unit that receives the return light of the illumination light detected by the plurality of respective light-receiving fibers, and performs photoelectric conversion to detect respective signal intensities; and an association unit that associates the respective signal intensities detected by the detection unit with distances from the illumination fiber to the respective light-receiving fibers on an end face of a distal end portion of the measurement probe, when light having an intensity gradient around the illumination fiber is projected to the end face of the distal end portion of the measurement probe.
