ABSTRACT:
An endoscopic apparatus includes an insertion section extending from an operating section and having a channel extending from the operating section to the distal end of the insertion section. The insertion section is adapted to be bent in a predetermined direction. A sheath is removably inserted into the channel and has a bendable portion located in the distal end portion of the insertion section. The bendable portion is remotely bent by an operating mechanism from the operating section to bend the distal end portion of the insertion section. The sheath is positioned in the insertion channel by a positioning mechanism so that the bendable portion is bent in the predetermined direction.
