Abstract

The endoscope has an image-guiding fiber bundle (15) extending in the direction of the shaft of the endoscope. The cross-section of the fiber bundle is arranged in a section of the shaft that does not contain other components. The cross-section of the fiber bundle is larger than the largest circular section that can fit into the free cross-sectional area. The cross-section of the image-guiding fiber bundle may be elliptical.
