Abstract
A suction nozzle for attachment to a partial vacuum source for removing smoke and liquid from a surgical area during laser or electrocautery surgery. The nozzle includes a cylindrical inner tube fixedly and concentrically attached within a cylindrical outer tube with the distal end of the inner tube extending forwardly of the distal end of the outer tube. A plurality of annularly spaced, radially extending connecting webs interconnect the outer and inner tubes together and define a respective plurality of discreet passageways through which the smoke and liquid are suctioned in addition to the passageway of the inner tube. An auxiliary nozzle may be attached to the exposed, distal end of the inner tube for passage through a trocar cannula or the like during endoscopic procedures. A flow control knob is also provided for removable and rotatable attachment to the distal end of the outer tube for selectively controlling the fluidics flow through the passageways between the connecting webs.
