Abstract: A flexible endoscope according to the invention is characterized in that, the endoscope comprising a removable and independent optical-illumination module (12) containing an elastic tube (12b) ended with a capsule (12a) while within the elastic tube (12b) an optical fiber bundles (12b4) and electrical wires (12b3) are ended with terminals for peripheral devices. Within the insertion tube (1) an optical-illumination channel (13a) is formed. A micro camera (12a6) equipped with lenses (12a3) and with terminals of optical fiber bundle (12b4) and electrical wires (12b3) is provided within the capsule (12a). If the optical-illumination module (12) is installed in the endoscope the capsule (12a) is placed stable in a distal tip (1a) that is formed by movable connected parts.

Abstract: The device for controlling an endoscopic insertion tube in accordance with the invention has a lever (1) which is movably mounted on a joint of at least two degrees of freedom which is fixed in the base (2a) or on a flexible element fixed to the base (2a). In the base (2a) four upper pins (8) and at least two lower pins (9) are mounted, each at 90 degrees angle. The ends of the upper arch guide (3) are fixed to the two opposite upper pins (8) and ends of the other opposite upper pins (8) are fixed to the ends of the lower arch guide (4). The upper arch guide (3) goes movably through the lever (1) right above the lower arch guide (4), which goes also through the lever (1). A movement of the lever (1) causes a movement of single arch guide or both arch guides simultaneously. At least two driving gears (5) are mounted on the perpendicular to each other upper pins (8). Every each driving gear (5) forms a transmission with a corresponding driven gear (6) mounted on the lower pin (9).
