Embodiment Construction

[0060] Such as figure 1As shown, the endoscope system 2 includes an electronic endoscope 3 , a processing device 4 , a light source device 5 , an air and liquid feeding device 6 , and a suction device 7 . The air supply and liquid delivery device 6 includes a known air supply device (pump, etc.) 11 built in the light source device 5 to send gas, and a liquid tank 12 provided outside the light source device 5 to store liquid. The electronic endoscope 3 has a flexible insertion portion 16 inserted into the body, a manual operation portion 17 connected to the base end portion of the insertion portion 16 , and a universal cord 18 connected to the processing device 4 and the light source device 5 . Cleaning water is used as the liquid sent by the air-sending and liquid-sending device 6 , and air or carbon dioxide gas is used as the gas sent.

[0061] The insertion part 16 has the front-end|tip part 16a, the bending part 16b, and the soft part 16c sequentially from a front-end|tip....

Abstract

The invention provides an endoscope capable of improving operatability in assembling. When an installation sheet (69) is inserted in an installation sheet insertion slot (82), a front end part of a thick wall part (67) is embedded with a thick wall part accommodating groove (81), and a connecting cylinder (53) is positioned in a circumferential direction relative to a front end part main body (51). A front end face of the thick wall part (67) abuts against a front end face (81a) of the thick wall part accommodating groove (81), and the connecting cylinder (53) is positioned in a cylinder center direction relative to the front end part main body (51). A mounting screw (88) is in threaded engagement with a threaded hole (83) of the installation sheet insertion slot (82) via a gap (52a) of a front end cover (52) and a screw insertion hole (69a) of the installation sheet (69), and the connecting cylinder (53) is fixed to the front end part main body (51). Assembling and fixing of the connecting cylinder (53) towards the front end part main body (51) can be performed in a simple and reliable manner.

Description

technical field [0001] The present invention relates to an endoscope equipped with a coupling tube having an opening formed at a distal end portion of an insertion portion. Background technique [0002] The endoscope includes a flexible insertion portion inserted into the body of a subject, and the insertion portion has a distal end portion, a curved portion, and a flexible portion in this order from the distal end. The front end includes a front end body. An observation window, an illumination window, and the like are provided at the front end of the front end body. The observation window acquires image light inside the subject's body. The lighting window emits lighting light. Behind the observation window, there is provided a camera unit for imaging the inside of the subject, and the camera unit is attached to the front end body in a state where a transmission cable is connected. In addition, the tip of the optical fiber cable for guiding light to the lighting window i...
