<p>An irrigation/aspiration system (10), comprises an irrigation line (31), wherein the irrigation line is configured to be connected to a source of irrigation fluid (29); an aspiration line (30); a collection chamber (18); a vacuum pump (12), wherein the vacuum pump is configured to introduce a vacuum into the collection chamber (18) to draw an irrigation fluid from the source of irrigation fluid (29) through the irrigation line (31), a surgical site, and the aspiration line (30) and into the collection chamber; control circuitry (24); an irrigation sensor (26), wherein the control circuitry (24) is configured to monitor irrigation fluid flow or irrigation fluid pressure in the irrigation line through use of the irrigation sensor; a flow pump (14), wherein the control circuitry (24) is configured to use the flow pump (14) and/or vacuum pump (12) to adjust a level of fluid in the collection chamber (18);a fluid level sensor (20), wherein the control circuitry (24) is configured to monitor a fluid level in the collection chamber (18) using the fluid level sensor; a pressure transducer (16), wherein the control circuitry (24) is configured to use the pressure transducer to monitor a vacuum in the collection chamber (18) from the vacuum pump (12). The control circuitry (24) is configured to vary the vacuum introduced into the collection chamber (18) based on the monitored irrigation fluid flow or irrigation fluid pressure and the monitored fluid level in the collection chamber so as to maintain fluid flow into the collection chamber through the aspiration line (30) at a selected flow rate.</p> |
