Abstract
A suction and irrigation apparatus is provided for selectively delivering suction or irrigation fluid to a patient during surgery or the like. A pair of resilient tubes are provided which is connected with a suction source and irrigation source at one end and is connected through a Y-shaped connector at the other end with a handpiece having clamping valves thereon disposed between the ends of the resilient tubes. The handpiece has a housing with openings in the ends thereof to provide passageways for the resilient tubes. Clamping valves are mounted in the housing which are spring urged to close the resilient tubes. A bracket is slidably mounted on the sides of the handpiece housing and the bracket is slidable to a position overlying the clamping valves so as to maintain the clamping valves in an open position. When the clamping valves are held in an opened position by the bracket, the handpiece can be moved along the length of the resilient tubes to position the handpiece at any desired location. When the handpiece is located in the desired position, the bracket is removed from the handpiece to release the clamping valves to close the resilient tubes.
