ENDOSCOPE AND ENDOSCOPE DEVICE

WIPO Patent Application WO/2011/099441

A1

A very easy to use endoscope which can be easily switched to forward observation and to backward observation without unnecessarily moving the entire endoscope while the endoscope is in the body. In the endoscope (1), an insertion section (10) is provided with: a shaft body (11) which connects to a cable section (30), extends rectilinearly, and is provided with an objective lens (11a) on the front end side thereof; and an observation direction change section (20) which is provided on the front end side of the shaft body (11). A reflecting mirror (20a) is rotatably mounted inside the observation direction change section (20) consisting of a transparent material. The attitude of the reflecting mirror (20a) in rotation includes a backward observation reference attitude in which the mirror surface faces the direction perpendicular to the direction of the axis of the shaft body (11). The reflecting mirror (20a) is rotated by a reflecting mirror rotation means, and forward observation which is performed without the reflecting mirror (20a) and backward observation or side observation which is performed through the reflecting mirror (20a) can be switched between each other.
