Abstract: A washing instrument comprises a washing instrument body to which a distal configuration portion of an insertion device is attached, a three-way cock which communicates with both a first washing opening and a second washing opening that spout out a washing liquid at different positions inside a receiving chamber of the distal configuration portion and thus switches communication directions and which adjusts a liquid supply volume, a liquid supply function comprising a syringe coupling portion having a syringe to supply the washing liquid and a check valve, and a movement regulating portion which positions the distal configuration portion at a position where the washing liquid is directly spouted out from the first washing opening and the second washing opening to a swing base that is provided in the receiving chamber and that swings the movement direction of the extension of a treatment instrument.

Abstract: A washing instrument for an insertion device performs positioning of a distal portion by an axial direction regulating portion provided in a cylindrical hollow washing instrument main body and abutting on the distal portion of the insertion device, and a rotating direction regulating portion facing an observation surface of the insertion device, thereby attaching the insertion device. A raised distal portion of a swing base received in a receiving chamber of the distal portion abuts on a projecting locking portion provided on an inner peripheral surface between the washing ports, the locking portion and the axial direction regulating portion hold a positioned state of the distal portion, and washing liquids jetting out from the washing ports directly collide with washing target regions of the receiving chamber to perform washing.

Abstract: A sealability acquiring mechanism disposed in a medical apparatus has a raising base unit constituted of a raising base operating mechanism, a raising tube path portion, a guide tube and a raising base. In the raising tube path portion, there is disposed a sealing member that is water-tightly or air-tightly fixed to a wire fixing portion to be connected to a raising wire inserted into an outer peripheral member and the outer peripheral member, a fluid supplied from an opening of the outer peripheral member flows between an inner peripheral surface of a raising tube path and an outer peripheral surface of the sealing member, and the raising base operating mechanism is water-tightly or air-tightly separated from the raising tube path.
