An apparatus for irrigating a local irrigation site includes a suction/irrigation tip that is removably connected to a suction/irrigation handpiece. The tip has an irrigation tube for directing irrigation liquid to the irrigation site, and a suction tube coaxially aligned within the irrigation tube. The handpiece pumps irrigation liquid from an external reservoir, through the annular space between the irrigation tubes and the suction tube to the irrigation site. Suction is applied to the site through the central suction lumen which has a large unobstructed opening to reduce clogging. A flexible splash shield, slidably mounted to the tip, is sonically shaped and extends distally from a collar to a rim. The rim is sized to fit around and about the local site.
L'invention porte sur un appareil d'aspiration et d'irrigation comportant un embout d'aspiration/irrigation réversiblement relié à une pièce à main d'aspiration/irrigation. L'embout présente en outre un tube d'irrigation dirigeant le liquide d'irrigation sur le site à irriguer et un tube d'aspiration monté coaxialement dans le tube d'irrigation. La pièce à main pompe le liquide d'irrigation provenant d'un réservoir extérieur à travers l'espace annulaire compris entre le tube d'irrigation et le tube d'aspiration sur le site à irriguer. L'aspiration est appliquée au site par la lumière centrale d'aspiration qui présente une large lumière libre de manière à réduire l'engorgement. Un pare-éclaboussures souple monté coulissant sur l'embout et de forme conique s'étend distalement entre un collier et un bord extérieur dimensionné pour s'adapter au site à irriguer et l'entourer.
