An endoscope is an instrument which consists of a tube of fibre optic fibres contained in a waterproof membrane. A light source is connected to the endoscope and transmits light down the fibres and back to an eye piece, allowing the operator to look at the region adjacent to the end of the endoscope. An endoscope can be used to look at remote body systems.
