ABSTRACT:
An endoscope comprises a hollow shank, optic viewing means positioned in the hollow shank for observing a body cavity, and a separate adjustable instrument channel which is axially, slidably arranged in an internal guiding region of the hollow shank. The instrument channel has a flexible curvature section and a laterally running end section with an end portion that is pivotably and articulably mounted in a radial passage in the distal circumferential wall region of the hollow shank. Sliding the instrument channel axially in the hollow shank results in flexing of the curvature section and pivoting of the end portion, such that an auxiliary instrument provided in the instrument channel is laterally deflected when guided through the hollow shank.
