Studies have shown that inhaling the electrosurgical smoke plume created by burning one gram of tissue is equivalent to smoking 6 unfiltered cigarettes. The Megadyne Mega Vac Smoke Evacuation System makes it easy to protect OR personnel from the hazards of electrosurgical smoke plume. The Mega Vac system is standard for use with open procedures, while Mega Vac Plus allows evacuation of laparoscopic smoke. The Megadyne Ultra Vac Smoke Evacuation Pencils are slim and ergonomically designed, with a telescope that extends to six inches. The tip can be adjusted to any length the surgeon desires, allowing smoke evacuation directly at the surgical site, which is most effective.
