<p>A suction-irrigation device having a hinged reusable housing (12,13) enclosing a disposable tri-tubular cassette (19) that is replaced each time the device is used. The three tubes (16,17,18) of the tri-tubular cassette (19) provide respectively for irrigation fluid, suction and instrument pass through. A pair of symmetrically positioned trumpet-type actuators (27,28) are equipped with fricton-reducing rollers and are disposed in a wedging configuration to selectively impart squeezing action on the irrigation fluid and suction tubes, thereby providing control that is provided for ambidextrous use, that is, it is equally adapted for left and for right handed use.</p> |
