Suction and irrigation handpiece and tip with retractable splash shield
First Claim
1. An apparatus for irrigating an irrigation site comprising:
- a handpiece defining a suction lumen and an irrigation lumen; and
a detachable tip having a proximal end and a distal end, the tip further comprising;
an irrigation tube;
a suction tube substantially coaxially disposed entirely within theirrigation tube; and
a connector for connecting the tip to the handpiece.

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.
