ABSTRACT:
A suction device is provided having a tube connectable at its proximal end to a vacuum source and open at its distal end to provide suction at the distal end. A porous barrier is located within the tube distal end, being either a rigid screen filter or supporting a compressible filter which is drawn against the barrier by the tube vacuum. The filter alternatively may be secured to a housing which is securable to the tube distal end. The device further has a second tube disposed around the first tube, with the second tube being closed at opposite ends around the first tube to define an irrigation channel therebetween. The channel is connected to an irrigation source and has discharge openings at its distal end. The suction and irrigation functions of the channels can be reversed with the small openings in the outer channel defining a rigid screen during suction.
