Abstract: Provided is an endoscope capable of operating a bending part with a higher degree of freedom while enabling a related-art operation of moving a pair of bending operating wires forward and backward. The endoscope has an insertion part having a bendable bending part; an operating part continuously provided on a proximal end side of the insertion part; a pair of bending operating wires inserted into the insertion part and fixed to a distal end side of the insertion part; a first bending operating mechanism that operates the bending part by moving the pair of bending operating wires forward and backward in conjunction with each other; and a second bending operating mechanism that operates the bending part by independently moving the pair of bending operating wires forward and backward.

Abstract: In an endoscope apparatus, a suction button unit (switching valve unit) includes a valve cylinder, a piston rod, a cap device and seal packing. Holes are formed in a piston chamber of the valve cylinder, including a discharge port hole, a suction port hole and an exhaust port hole. The piston chamber includes a piston slide surface and a sliding sealing surface. A passage in the piston rod connects the exhaust port hole with the suction port hole in case the piston rod is in a halfway position, and connects the suction port hole with the discharge port hole in case the piston rod is in a position of full depression. The seal packing, in the halfway position, closes the discharge port hole, and in the position of full depression, causes the discharge port hole to open. Thus, operability and washability of the suction button unit can be high.

Abstract translation: 在内窥镜装置中，抽吸按钮单元（切换阀单元）包括阀筒，活塞杆，盖装置和密封垫。 孔形成在阀筒的活塞室中，包括排出口孔，吸入口孔和排气孔。 活塞室包括活塞滑动表面和滑动密封表面。 在活塞杆处于中间位置的情况下，活塞杆中的通道将排气孔与吸入口孔连接，并且在活塞杆处于完全凹陷的位置的情况下将吸入口孔与排出口孔连接 。 中间位置的密封填料封闭排放口孔，在完全凹陷的位置使排气孔打开。 因此，吸引按钮单元的可操作性和可洗性可以很高。
