Suction and irrigation apparatus
First Claim
1. A suction and irrigation handpiece for controlling flow through resilient tubing comprising, top and bottom walls interconnected with a pair of sidewalls and a pair of end walls to form a hollow housing, a pair of apertures in each end wall, a pair of resilient tubes extending through said apertures to provide passageways through the housing, a pair of clamping valves extending through the top walls of the housing and engaging said resilient tubes, said clamping valves being slidable within the housing to open and close said resilient tubes, spring means within said housing and engaging said clamping valves for urging said clamping valves to a position to close the resilient tubes and releasable means on the housing and further including recesses in the sidewalls of said housing, said releasable means comprising a slidable bracket which slides in said recesses to retain said clamping valves in a position to open the resilient tubes so that the suction and irrigation handpiece can slide along the length of the resilient tubing to be positioned at any point convenient for use by the physician.

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.

- 7. A suction and irrigation apparatus comprising a pair of resilient tubes having connector plugs on one end thereof for connection to a suction source and an irrigation source, the other end of said tubes being secured to a Y-shaped connector plug for selectively delivering suction or irrigation to the outlet of the Y-shaped connector plug, a handpiece including a housing having passageways therethrough for said resilient tubes and clamping valves mounted within said housing and engaging said tubes, spring means disposed within the housing and urging said clamping valves to a closed position and a slidable bracket mounted on said housing for simultaneously locking said clamping valves in an open position so that said handpiece can be readily moved to any desired position along the length of the resilient tubes.
