Abstract
A fluid handling system is disclosed for use with a surgical handpiece in microsurgery. Included is a fluid interface block apparatus which is structurally adapted to be removably and firmly secured to a control unit of the type which controls the fluidics of a microsurgery system. The system includes a plurality of peristaltic pumps arranged with respect to each other so as to minimize the effects of fluid pressure pulsations produced by each one.
