<P>PROBLEM TO BE SOLVED: To prevent bubbles from blocking the view of an observation window when a constant-pressure gas is supplied via a treatment tool channel opening formed in a leading end surface of a flexible endoscope, to thereby secure the view. <P>SOLUTION: In an attachment for an endoscope to be attached to a leading end part of the endoscope, an observation window for observing the inside of the body of a subject and a first opening for jetting a constant-pressure supplied gas are formed at a leading end surface. The attachment includes: a second opening provided at a position distant from the leading end surface; a pipe conduit that connects the first opening and the second opening with each other so as to jet the constant-pressure supplied gas from the second opening; and a region separating member that separates a jetting region of the constant-pressure supplied gas jetted from the second opening from a region of view of the observation window. <P>COPYRIGHT: (C)2012,JPO&INPIT |
