Abstract
An endoscope with a distal housing element which has a lens element, and with a nozzle element for cleaning the surface of the lens element. The lens element is a curved lens element, the curvature of which protrudes from the housing element in a distal direction. The nozzle element is arranged at the distal side of the distal housing element adjacent to the curved lens element. The nozzle element has a distal nozzle opening in the form of an elongated medium outlet slit directed toward the curved lens element.

An endoscope comprising
- a distal housing element having a lens element, and
- a nozzle element for cleaning the surface of the lens element;
- wherein
- the lens element has a convex distalmost lens surface which protrudes from the housing element in a distal direction,
- the nozzle element is arranged at a distal side of the distal housing element adjacent to the lens element,
- the nozzle element has a distal nozzle opening in the form of an elongated medium outlet slit, directed toward the lens element such that a flow exiting from the nozzle element flows over a side of the distalmost lens surface facing away from the nozzle element,
- the distalmost lens surface extends distally beyond the nozzle element, and
- the nozzle element is inclined such that the flow exits toward the distal direction.
