This invention relates to an endoscope for endonasal surgery for which different optical systems are required. With this invention it is possible to exchange an optical system and/or a matching flushing and suction shaft as desired while still utilizing the same endoscope shaft handle and without requiring the interchange of the complete endoscope including its handle. To accommodate this function, the handle including flushing and suction passages can be mated with interchangeable flushing and suction shafts and a desired optical system. Such shafts and optical system are releasably connected to the endoscope handle.
