Abstract
A surgical irrigation and aspiration system for aspirating fluid from a surgical site, such as the eye, including a surgical tool having irrigation and aspiration functions, and an irrigation fluid supply for providing irrigation fluid to the surgical tool. A peristaltic pump pumps aspiration fluid from the surgical site generally through and away from the surgical tool and through an aspiration flow line to a collection container. A dampening mechanism in the aspiration flow line before the pump dampens the oscillations of the aspiration fluid flow, caused by the inherent operation of the peristaltic pump, in the aspiration flow line, and thereby at the surgical site.
