Endoscope system and assist device

摘要

An endoscope system includes a nasal endoscope (10, 150) for entry in a first external nostril of a patient, and an assist device (12, 140) for entry into a second external nostril. A retaining device (23, 24, 40, 41, 151) removably retains the second distal portion on the first distal portion. The endoscope includes an image pickup device (63) for picking up an image of an object through an imaging window (55), and a steering section (21) for steering a distal portion of the endoscope at least in an upward or downward direction upon operation of a steering mechanism (28). The system also includes a display panel (15) for displaying an image as picked up by said image pickup device, with said image displayed such that the upward direction of the image corresponds to an upper side of steering of said steering section.
