    摘要： An endoscope according to the present invention comprises an observation optical system and an insertion section which includes a bending tube. A plurality of segments, which are rockably connected to one another, are arranged in the bending tube, and wire guides are fixed to the inner peripheral surface of each segment. One end of each of bending-control wires is fixed to the segment at the distal end portion of the bending tube. The other end of each wire extends to the proximal end portion of the insertion section, through the wire guides of the other segments. In this arrangement, the bending tube is bent by pulling the other ends of the bending-control wires. The endoscope further includes bending means arranged in the bending tube and adapted to bend, when the bending-control wire is pulled, the bending tube for moving the observation optical system such that the center of the system moves from the center of the insertion section to the periphery thereof. Thus, even though the bending tube is bent sharply, the position of a flexible tube of the insertion section, which may possibly obstruct the field of view, can be shifted to the right or left from the center of the field, thereby keeping the view field entire.

    摘要： In an endoscope system including an endoscope having an insertion section to be inserted into a cavity under inspection, a bending portion which is provided in said insertion section near a distal end thereof and is bendable in at least two different directions and an operation section to which a proximal end of the insertion section is connected and a disposable protection cover having an insertion section cover for covering said insertion section of the endoscope and having formed therein an insertion section inserting channel into which said insertion section of the endoscope is insertable and at least one conduit channel, said insertion section and bending portion of the endoscope are formed to have a non-circular lateral cross section, a direction in which said non-circular cross section has a larger size is aligned with a direction in which said bending portion is bent by a maximum bending angle or a direction in which said non-circular cross section has a smaller size is aligned with a direction in which said bending portion is bent by a minimum bending angle.

    摘要： A cover-fit endoscope can be used while being covered with a cover so that it is watertight. An appliance channel is extended through the cover and an appliance insertion inlet of the channel is open. This opening of the appliance insertion inlet is provided with an integral appliance plug. It is therefore possible to prevent the contaminated appliance plug from being fitted to the sterilized cover by mistake, and also to prevent leakage of the body fluids. Thus, the cover-fit endoscope is kept from contamination. The cover and the appliance plug are both discarded after use. The need for washing and disinfecting the cover-fit endoscope is eliminated, and use of the sterilized appliance plug is always ensured to reduce a fear of infection.
