Abstract: An endoscope comprising an endoscope shaft (2) having in the front end portion a movable section, with the endoscope shaft (2) having provided therein at least one miniaturized electric drive member (22) for moving the movable section (4).

Abstract: An apparatus for moving an endoscope along a canal-shaped cavity includes an endoscope having a movable distal end for entry into the cavity and a stationary operating end which remains outside of the cavity. A first portion of the endoscope is contained in a turnout tube which has a turnout area for entry into the cavity, and which also has a fixed end which remains outside of the cavity. A second portion of the endoscope extends from the fixed end of the turnout tube to the operating end of the endoscope. A first drive assembly is operable to move the endoscope and the turnout tube in unison, and a second drive assembly is operable to move the endoscope independently of the turnout tube. A lubricant may be applied through the fixed end of the turnout tube to the portions of the endoscope which are disposed within the turnout tube.

Abstract: An endoscope device includes an endoscope tube having a forward head piece and a flexible eversion tube for moving the head piece into a channel-like body cavity by means of fluid pressure. The eversion tube has an outer portion; a turning portion engaging the head piece; and a rearwardly extending inner portion. A first fluid pressure is exerted in a space between the outer portion and the inner portion of the eversion tube, which space is sealed from ambient surroundings. A second fluid pressure is exerted in a space between the endoscope tube and a rearwardly extending inner portion of the eversion tube.
