Abstract
An endoscope with an insertion tube having a proximal passive flexible section and a distal bending section. Cuts are provided in the proximal passive flexible section. Adjacent cuts are unequally spaced in the proximal passive flexible section. The proximal passive flexible section has secondary cuts adjacent to main cuts, wherein the secondary cuts are arranged closer in the longitudinal direction of the proximal passive flexible section to the adjacent main cuts on one side of the secondary cuts than to the adjacent main cuts on the other side of the secondary cuts. The main cuts extend along the circumference of the proximal passive flexible section in an interrupted manner. The proximal passive flexible section includes the main cuts, wherein at least within a subzone in the proximal passive flexible section, the main cuts are unequally spaced from each other in the longitudinal direction of the proximal passive flexible section.
