This principle is known as the Venturi effect. When flowing through a constricted area of a pipe, a fluid's velocity increases and its static pressure decreases. The Venturi Effect was discovered by Italian physicist Giovanni Battista Venturi who lived between 17. The Versajet® system is based on the Venturi principle:Ī thin high-velocity jet of water consisting of sterile saline is discharged from a 0.12-mm nozzle into a suction tube. The quantity of ablated tissue is determined by the pressure settings at the console (1-10), the pressure exerted by the surgeon, and the speed at which the handpiece is moved on tissue. When the working tip is tilted slightly the scalpel effect of the water jet is reduced while the rinsing and suction effect is enhanced. This aspirates, cuts and suctions the tissue.Īs the handpiece is held parallel to the wound the high-pressure water jet acts as a scalpel. The consistency of the working tip and the velocity of the water jet create a vacuum below the incision window. The wound is rinsed without significant aerosolization. The Versajet® is a hydro surgical system employing a jet of water by which tissue is simultaneously cut, ablated, and suctioned. It is essential to preserve and protect vital tissue. Prerequisites are exact determination of the depth and accurate debridement. Early debridement and depth-specific coverage are currently the standard in the surgical treatment of burns.
