Abstract:
1. An endoscope comprising: an end cap accommodating at least a lighting means mounted on an electric circuit board and an optical means comprising a lens system and a light sensitive sensor, wherein the circuit board forms an axially lower sealing cover of the end cap, the end cap being mounted on the front of a manually bendable adapter of an endoscope shaft; and a cooling means for cooling electronic components including the lighting means inside the end cap, wherein the cooling means comprises: wherein the cooling circuit and the cooling chamber form part of the bendable adapter and wherein the cooling circuit and the cooling chamber are axially distanced from the end cap, wherein an axially upper sealing cover of the cooling chamber is formed by at least one of the electric circuit board or an axially upper end plate that abuts the electric circuit board, and wherein the cooling chamber is fluid-sealed by the electric circuit board or by the axially upper end plate so that the cooling fluid is feedable through the cooling chamber so that upon placing the end cap onto the adapter, the cooling means is brought into thermal contact directly with the electronic components to be cooled or with bridging parts connected to the electronic components.
