<P>PROBLEM TO BE SOLVED: To secure a visual field by preventing the visual range of an observing window from being shut out by bubbles generated near a gas jetting opening when supplying constant pressure gas via an opening formed in the distal end face of a soft endoscope. <P>SOLUTION: The endoscope has a proximal side operation part, an insertion part constituted by arranging a distal end part, a curved part, a soft part in this order from a distal end side to a proximal end side where the proximal operation part is arranged, wherein the distal end part has a distal end face in which the observing window for observing the inside of a subject is arranged, the curved part is remotely curved and operated by the operation of the proximal side operation part so as to direct the distal end part in optional directions, the soft part connects the curved part and the proximal operation part and is curved in optional directions along an insertion direction into the subject, a gas feeding channel formed in the insertion part, a gas jetting opening communicating with the gas feeding channel and arranged in the proximal end side from the distal end face where the observing window is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
