Abstract
An assembly for a phacoemulsification surgical system includes an aspiration system arranged to aspirate fluid from a surgical site. The aspiration system includes an aspiration path within the phacoemulsification hand piece and includes a flexible small bore aspiration tubing in fluid communication with the aspiration path. The small bore aspiration tubing has a nominal inner diameter smaller than about 0.050 inch to reduce levels of occlusion surge within the surgical system. A high-output, peristaltic pump communicates with the small bore aspiration tubing and is operable to create a flow through the small bore aspiration tubing.
