Endoscope sheath, endoscope system and method for providing an endoscope system

摘要

The endoscope sheath (1) has a long extended flexible hose (3) that encloses a main lumen (2) for receiving a portion of a shaft of a flexible endoscope and a working channel (4) for receiving a portion of a flexible endoscopic working instrument. The endoscope sheath has a transparent distal end section which is formed by the hose in a separating manner. the working channel is guided in the form of a helical line around the main lumen and runs in the distal end section parallel to a central longitudinal axis of the main lumen. An independent claim is included for a method for operating an endoscope arrangement.
