An endoscope has an outer shaft, in which an optical channel receiving an optical system is arranged, wherein in the outer shaft, further, a channel for receiving a working element, at least one supply channel extending longitudinally for a medium and at least one discharge channel extending longitudinally for the discharge of a medium, the discharge being separated from the supply, are arranged. The optical channel and the at least one supply channel and/or the at least one discharge channel are configured as chambers of a profiled shaft, which is chambered in its cross section and received in the outer shaft.

Endoscope

An endoscope has an outer tube that is joined to an optical head having an observation element at its end, which elements are sealingly fitted forming a first module element. An inner tube sealingly fitted together with a housing containing optical elements form a second module element having the optical components hermetically closed. The second module element is disposed in the first module element having its distal ends rigidly and sealingly fitted together. The housing of the second module elements extends into said optical head of that first module element and is supported therein allowing relative movement between housing and optical head when thermally stressed.
