Abstract
A surgical irrigation system utilizing a flow sensor device; upon sensing fluid flow, the flow sensor device activates a fluid acceleration or pumping mechanism to pump fluid to a surgical site; the flow sensor device is capable of being conveniently located between an elevated source of fluid and a surgical handpiece; since the flow sensor device activates the pumping mechanism, the surgical handpiece is liberated from use of an electrical-type switch to activate the pumping mechanism, and, instead, is provided with a valve for mechanically starting and stopping fluid flow.
