Abstract

This insertion device is provided with: a tube (30) provided with a passage hole (32) and a communication hole (32s); a frame member (41) in which a tube insertion hole (46) and a forceps channel (47a) are formed, the frame member (41) being disposed so as to cover the periphery of the communication hole (32s); and a closing member (70) which closes the passage hole (32) in the tube (30) at a position closer to the base end side than the communication hole (32s), and which is disposed so that the front end surface (73s) faces the communication hole (32s).

Description

technical field [0001] The present invention relates to an insertion device including a tube having a hole formed along the long axis of an insertion portion inserted into a subject. Background technique [0002] In recent years, insertion devices such as endoscopes have been widely used in the medical field. The endoscope can observe the internal organs in the body cavity by inserting the elongated insertion part into the body cavity of the subject, or use the treatment instrument inserted into the tube of the endoscope (mother endoscope) as needed Or a known sub-endoscope for observation of finer parts or various treatments. In addition, the term "mother endoscope" refers to an endoscope in which an insertion portion of a child endoscope is inserted into a channel. [0003] And, as a channel, there is known a tube provided in the insertion part and the operation part of the endoscope, which has a hole (hereinafter referred to as a first hole) through which a treatment in...
