Abstract
A hand-held suction-irrigator, particularly for surgical use, has a handle and two inlet bores extending through the handle and connected respectively to a suction source and a source of irrigating fluid. A valve assembly connects one or the other of the bores to a single outlet port so that the outlet port can be used to apply suction or irrigating fluid. A probe is removably coupled to the outlet port by cooperating luer fittings. The two inlet bores are parallel with one another, the outlet port being located intermediate the inlet bores on the opposite side of the valve assembly. A valve member is mounted in the valve assembly and can be displaced transversely of the bores by pushing down on the valve member with a finger or thumb.
