    Abstract: An insertion portion mounted tool of an insertion instrument includes: an expansion and retraction section provided on an outer circumferential side of an insertion portion so as to be movable forward and backward in a longitudinal direction, and configured to be expanded in the subject by an operation from outside of the subject to thereby be held by an inner wall of the subject; a positioning portion that defines a range in which the expansion and retraction section is movable forward and backward in the longitudinal direction with respect to the insertion portion; and a rotational movement restriction portion that restricts an angle in which the expansion and retraction section is rotationally moved in an outer circumferential direction on an outer circumference of the insertion portion.

    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.

    Abstract: The disclosed technology is directed to an endoscope comprises an operation portion. An insertion portion having respective proximal and distal ends. The proximal end is configured to be attached to the operation portion and the distal end is used to be inserted into a subject. The distal end of the insertion portion includes a distal surface having at least an observation window, a channel opening, and an elongated feed conduit having a slanted feed passage all which formed therein to communicate simultaneously with the operation portion and a procedure instrument during an operation on the subject. The elongated feed conduit having the slanted feed passage used to direct fluid into the subject. The slanted passage feed includes an ejection port that ejects the fluid from the slanted feed passage at an angle to generate a vortex flow so that mucus or mist-form particles are diffused away from the observation window.
