Abstract
A surgical system comprises a pressurized irrigation fluid source with a flexible bag located between two opposing plates. An irrigation line is fluidly coupled to the pressurized irrigation fluid source. A hand piece with an irrigation sleeve is fluidly coupled to the irrigation line. A controller controls the pressurized irrigation fluid source based on a rate of change of a source pressure associated with the pressurized irrigation fluid source and a rate of change of a linear displacement of one or both opposing plates.
