    Abstract: A high-frequency treatment tool for an endoscope includes: a sheath formed of a material having an insulation property; a shaft-shaped member formed of a material having conductivity and inserted to advance and retract in the sheath; and an electrode having a conduit line formed to jet forward a fluid supplied into the sheath, and connected to a distal end section of the shaft-shaped member. The electrode has an outer circumferential surface electrically connected to a contacted tissue to perform treatment, and an inner circumferential surface of the conduit line that faces the fluid when the fluid is supplied. An arithmetic average roughness of the outer circumferential surface is larger than an arithmetic average roughness of the inner circumferential surface, and the arithmetic average roughness of the inner circumferential surface is 0.1 μm or less.

    Abstract: An insertion apparatus includes an endoscope, a first air feeding apparatus, a first air suction apparatus, a second air feeding apparatus, a second air suction apparatus, a pressure detector, an operation detector and a controller, and the controller performs first control on the second air feeding apparatus and the second air suction apparatus so that the amount of gas per predetermined time period fed from the second air feeding apparatus becomes equal to the amount of gas suctioned by the second air suction apparatus, and when the operation detector detects the operation and the pressure detector detects that the pressure in a subject changes from a first pressure to a second pressure, the controller maintains the first control to perform air feeding/air suction into/from the subject at the second pressure.
