Abstract

L'invention concerne un dispositif à endoscope dans lequel une première et une deuxième conduites de fluides sont disposées dans un tube d'endoscope souple (3) dans la direction axiale de celui-ci. Un ballonnet (4) dilaté par l'air, rempli à partir de la première conduite, est fixé sur la partie de pointe d'extrémité périphérique du tube d'endoscope souple (3), et un corps de tube externe d'aspiration (35) possédant plusieurs trous d'aspiration (36), disposés à des intervalles appropriés dans la direction axiale de manière à communiquer avec la deuxième conduite de fluides, est fixé près de la partie de pointe d'extrémité périphérique de la base du tube d'endoscope (3), près du ballonnet (4). On remplit avec de l'air ce ballonnet (4) du tube d'endoscope (3) inséré dans le gros intestin à travers la première conduite à fluides, la partie interne du corps de tube externe d'aspiration (35) étant mise sous pression négative à travers la deuxième conduite à fluides, un enteron (C) étant bloqué de manière à ce que ses parois internes soient aspirées dans les trous d'aspiration (36) formés à la surface périphérique du corps de tube externe d'aspiration (35). L'enteron (35) est raccourci vers le côté d'extrémité de la base du tube d'endoscope (3) lorsque ce dernier est tiré vers le côté d'extrémité de base dans cet état ; le ballonnet se contracte par la suite, la pression négative du corps de tube externe d'aspiration (35) est relâchée, et le tube d'endoscope (3) est déplacé vers l'avant.
