    摘要： An electronic endoscope apparatus provided with an electronic endoscope having arranged thereon a solid-state image pickup element at an insertion portion, and external devices such as a light source device for supplying an illumination light to the electronic endoscope, a video processor for processing an electrical signal transmitted from the solid-state image pickup element of the electronic endoscope to produce a video signal. An electrical connection portion for electrically connecting the electronic endoscope and the video processor is provided at a connector portion which is provided at an end of a universal cord which connects the electronic endoscope and the light source device. An electromagnetic interference countermeasure member is provided which covers at least one of the connector portion, the universal cord and the external devices. A dual shield around a signal line is also provided which includes spirally-wound lead wires having different diameters and ends connected to video ground.

    摘要： In an endoscope of the present invention, while a cover indicator on a distal cover is aligned with a scope indicator on a main distal part, the distal cover is put on the main distal part in an axial direction at a certain insertion angle. Thereafter, the distal cover is rotated while being thrust in the axial direction. The stoppage of a locking convex part of a hook of the main distal part by a claw of a reinforcement member is released, and the locking convex part of the hook is positioned in a locking ditch of the reinforcement member. The head of the hook is constrained to move in the axial direction by means of a main distal cover that is an elastic member and the claw. The locking convex part is then fitted into the locking ditch reliably. Consequently, the distal cover can be fixed to the main distal part readily, freely detachably, and reliably with high positioning precision.

    摘要： An edge portion of an endoscope inserting portion includes an observation optical system, a first treatment-tool oscillating base which guides, in a first direction, a first treatment tool guided via a first channel for inserting the treatment tool, and a second treatment-tool oscillating base which guides, in a second direction, a second treatment tool guided via a second channel for inserting the treatment tool. Upon endoscope treatment for the lesion portion using the first and second treatment tools which are projected from the edge openings of two first and second channels for inserting the treatment tool and which are guided by the two first and second treatment-tool oscillating bases, one of the first and second treatment tools is moved to the outside of a field of view of an endoscope image as needed.

    摘要： A treatment instrument passage channel through which a treatment instrument can be passed lies through an elongated insertion unit that is inserted into a body cavity or the like. The distal opening of the treatment instrument passage channel opens onto the distal part of the insertion unit. A treatment instrument swing stand having a hole, through which the distal part of a treatment instrument led out of the distal opening is passed, bored therein is disposed near the distal opening so that the treatment instrument swing stand can swing freely. The treatment instrument swing stand is manipulated by proximally pulling angling wires. Thus, the distal part of the treatment instrument is swung from a position near the center of a field of view in both the rightward and leftward directions of an endoscope. Thus, the mucosa of a lesion can be resected easily while being caught in the field of view.

    摘要： An endoscope device has an endoscope provided with a front end portion where a nozzle and a sucking opening are formed. A first passage and a fluid supply pump are connected to the nozzle to supply fluid to it. A second passage and a suction pump are connected to the sucking opening. Connected to the first and second passages are a third passage and a pump for circulating the fluid in such a way that it is sucked through the sucking opening and jetted through the nozzle.
