Abstract
A lavage/suction tip comprising an elongated barrel with a first pliable conical shield extending outwardly from the distal tip of the barrel and a second substantially rigid conical shield which is slidable upon the barrel. The lavage/suction tip is utilized to provide irrigating fluid to a surgical site while providing suction to remove fluids and debris away from the surgical site. The first shield helps to eliminate splashback of the fluid. The second shield may be positioned to surround the first shield to provide firm support about the first shield, yet with a flexible, pliable tip perimeter. Alternatively, the second shield may be secured on the tip spaced away from the first shield so that the pliable first shield is used alone and may be easily, manually formed to more closely match the tip of the first shield to the working area or surface of the surgical site.
