Abstract: There is provided an endoscope and a treatment tool-standing mechanism that allows a distal-end-portion body to be reduced in size while ensuring good operability of a standing base. In a distal-end-portion body of an endoscope, a standing lever is connected to a standing base through a rotating shaft, and the standing base is rotated by the rotation of the standing lever about the rotating shaft that is caused by the push and pull of an operation wire. The standing lever includes a first arm portion that extends from the rotating shaft and a second arm portion that extends in a direction different from the direction of the first arm portion, and a useless space formed on the proximal end side of the distal-end-portion body is reduced depending on the shape of the standing lever.

Abstract: An endoscope includes a standing base in a tip portion body, an operation wire of which a tip side is connected to the standing base, and a stretchable coating member that covers the operation wire along an extending direction of the operation wire and so as to allow the operation wire to be relatively movable over the entire region from a connection portion between the standing base and the operation wire to an operation wire-guide passage. A tip of the coating member and the standing base are liquid-tightly fixed to each other, and a base end of the coating member and the operation wire-guide passage are liquid-tightly fixed to each other, and the coating member is disposed at a position where a moving path of the coating member and a moving path of a treatment tool led from a treatment tool-guide passage do not interfere with each other.

The configuration of the rotating shaft and a positional relation between the rotating shaft and the seal member are improved so as to reduce time and labor taken for cleaning processing of the endoscope.

Abstract: The endoscope is provided with the forceps elevator which is erectably provided in the distal end part of the insertion part of the endoscope and guides a treatment tool led out from the distal end part. The forceps elevator has an erecting motion range from a minimum angular position to a maximum angular position. If a state in which the treatment tool is not led out from the distal end part is assumed, the erecting operation lever for operating the movement of the forceps elevator has: a first operation range where the erecting operation lever is operated within the erecting motion range of the forceps elevator; and a second operation range where the erecting operation lever is operated beyond the first operation range. When the erecting operation lever is operated into the second operation range, the locking mechanism locks the movement of the erecting operation lever.
