End of endoscope

Abstract

Abstract Translated from Japanese (57)【要約】 【目的】弾性変形させることによって挿入部先端に設け られた先端部本体に対して着脱される先端カバーに流体 噴出ノズルを形成した内視鏡の先端部において、流体噴 出時に先端カバーが先端部本体から浮きあがらないよう にした内視鏡の先端部を提供することを目的とする。 【構成】先端部本体２と先端カバー２１との係合面の少 なくとも一部を、流体噴出ノズル２７，２４から流体を 噴出させたときに先端部本体２の表面から先端カバー２ １が浮きあがるのを妨げる向きの斜面２２に形成した。 (57) [Abstract] [Purpose] When a fluid is ejected at the tip of an endoscope in which a fluid ejection nozzle is formed in a tip cover that is attached to and detached from a tip body provided at the tip of an insertion portion by elastic deformation. An object of the present invention is to provide a distal end portion of an endoscope in which a distal end cover is prevented from rising from a distal end portion main body. [Structure] At least a part of the engagement surface between the tip body 2 and the tip cover 21 is ejected from the surface of the tip body 2 when fluid is ejected from the fluid ejection nozzles 27 and 24. 1 was formed on the slope 22 in a direction in which it prevents the 1 from rising.
