摘要： A device to be incorporated in the housing of the operation section of an endoscope, for operating a bending mechanism incorporated in the insertion section of the endoscope, comprises an operation shaft and a holder. The operation shaft has a distal end connected to the bending mechanism and a proximal end portion projecting from an operation section of the endoscope. The holder is mounted on a distal end portion of the operation shaft and comprises an upper and lower cover which are joined together and which define an outside surface and a hollow cylindrical space around the operation shaft. The upper and lower covers abut each other to form an interface on the outside surface.

摘要： An endoscope includes an operating portion placed outside a living body, an insertion portion having a proximal end portion coupled to the operating portion, a distal end portion inserted in the living body, and an instrument insertion channel extending through the insertion portion, a raising mechanism having an operation wire and designed to direct the distal end portion of an instrument, caused to extend through the channel, to a predetermined position, and an operation means for operating the operation wire. The endoscope includes a distal end body portion arranged at the distal end portion of the insertion portion and incorporating an observation means for observing the interior of the living body, a support member for forming at least a portion of the outer surface of the distal end portion. The support member is detachable from the distal end body portion. The endoscope further includes a raising base which is supported on the support member such that the angle at which the raising base is arranged can be adjusted. The angle of the raising base is adjusted by the operation wire. The operation wire is detachable from the operation means.

摘要： An endoscope has a channel switching device for use in switching over a suction channel. The channel switching device consists broadly of a cylinder unit and valve unit. The valve unit can be disassembled into three component parts; a button assembly, piston assembly, and mount assembly. The button assembly has a cap, which is made of a rigid resin such as polyether ketone (PEEK) or polysulfone (PSU), as the uppermost part thereof. Since the cap is made of a rigid resin durable to autoclaving; such as, PSU or PEEK, the valve unit will not be damaged due to autoclaving. Even when the autoclaved valve unit is put to use though it is not yet cooled down, an operator will not perceive heat very much but can manipulate the endoscope as he/she intends.
