ENDOSCOPE AND RELATED SYSTEM

摘要

An endoscope (100) is described in which the diameter of the image relay assembly (110) is less than that of the objective lens assembly (106). An endoscope sheath (200) is also described for sheathing the endoscope (100) and housing or directing optical fibers (218) for use in illuminating the endoscope field of view. An endoscope-sheath system (300) is further described comprising the combination of the endoscope (100) and the endoscope sheath (200).
