  • Patent number: 6156004
    Abstract: 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 conically shaped and extends distally from a collar to a rim. The rim is sized to fit around and about the local site.
