Abstract

L'invention concerne un cylindre de manchon d'endoscope, utilisé pour être emmanché à l'extrémité avant d'un endoscope (1), comportant un corps cylindrique (2) et plusieurs composants saillants (3) disposés sur le corps cylindrique (2). Plusieurs trous de liaison (23) sont ménagés sur la paroi cylindrique du corps cylindrique (2). Les composants saillants (3) comportent des premières parties saillantes (31) s'étendant vers l'intérieur du corps cylindrique (2) et des secondes parties saillantes (32) s'étendant vers l'extérieur du corps cylindrique (2). Des connexions (33) des premières parties saillantes (31) et des secondes parties saillantes (32) sont reliées ou fixées pivotantes à la paroi cylindrique par l'intermédiaire des trous de liaison. Les composants saillants (3) tournent, avec les connexions (33) en tant qu'axes, autour de ceux-ci dans la plage de 0° à 180 °. Les premières parties saillantes (31) interagissent avec une paroi externe (13) de l'endoscope. Les angles, α, entre les premières parties saillantes (31) et les secondes parties saillantes (32) sont de 90° à 270 °. Les angles, β, entre les secondes parties saillantes (32) et la ligne d'axe central sont de 25° à 155 °. Le manchon fournit l'état avantageux d'une résistance minimale ou d'une absence de résistance pour l'endoscope entrant dans la cavité corporelle, et fournit à l'endoscope une vision élargie et nette lors de la sortie d'un contrôle de cavité corporelle, atteignant ainsi le but de l'absence de douleur pour le patient et augmentant la précision des contrôles.
