Abstract

La présente invention concerne une base de tête d'endoscope qui peut éliminer les points morts de stérilisation et un endoscope, la base de tête d'endoscope comprenant : une base formant support et un dispositif de levage de forceps (100), la base formant support comportant une cavité (102), destinée à être utilisée pour la mise en place du dispositif de levage de forceps (100), tandis que la cavité comporte une ouverture, destinée à être utilisée pour le levage du dispositif de levage de forceps (100) ; au moins un orifice d'entrée de liquide (101) et un orifice de sortie de liquide (103) sont disposés sur une paroi latérale qui se trouve autour pour former la cavité (102) sur la base formant support, un liquide de stérilisation étant injecté dans la cavité (102) par l'orifice d'entrée de liquide (101) et étant évacué par l'orifice de sortie de liquide (103). Le liquide de stérilisation peut être directement injecté dans la cavité (102) par l'orifice d'entrée de liquide (101), nettoyant et stérilisant la cavité (102) avant d'être évacué par l'orifice de sortie de liquide (103), empêchant ainsi les points morts de stérilisation tout en empêchant le liquide de stérilisation d'être retenu dans une partie interne de la cavité. La présente invention présente une structure simple et peut être facilement commercialisée et mise en œuvre.
