摘要： A surgical system comprises a hand piece, an irrigation conduit in fluid communication with the hand piece to carry fluid toward a surgical site, an aspiration conduit in fluid communication with the hand piece to carry fluid away from the surgical site, a pump interfacing with the aspiration conduit, the pump to create a vacuum pressure in the aspiration conduit to draw fluid through the aspiration conduit, a vacuum relief valve in fluid communication with the aspiration conduit to relieve the vacuum pressure in the aspiration conduit, a pressure sensor to detect a pressure associated with the surgical site, a controller in communication with the vacuum relief valve and the pressure sensor to control the vacuum relief valve to decrease the vacuum pressure in the aspiration conduit when the pressure detected by the pressure sensor is less than a first pressure threshold.
