Abstract
An endoscope has a video device arranged at the distal end of the endoscope shaft. The video device is connected by means of a transmission system to a supply unit arranged at the proximal end of the endoscope shaft. The video device is provided with a lens for imaging an object field and an illumination unit. The lens and the image recorder are combined into a video unit which is held in such a movable manner at the endoscope shaft that the outer contour of the cross-section of the video unit lays essentially within the outer contour of the cross-section of the distal end of the endoscope shaft when being introduced into the cavity to be examined. After termination of the introduction procedure, the video unit can be moved in relation to the distal end of the endoscopic shaft beyond the outer contour of the cross-section and/or longitudinal section.
