Abstract
A rapid pulsatile smoke extraction system includes a laser handpiece having a sleeve configurable to be applied to tissue; a vacuum pump and a vacuum reservoir; a conduit connecting the reservoir with the sleeve; and a valve inserted in the conduit. A volume of the vacuum reservoir is at least two times larger than a volume of the sleeve, such that operation of the valve supports instantaneous evacuation of smoke and particulate products from the sleeve into the vacuum reservoir.
