Abstract
Abstract A smoke removing device used with an electrosurgical device consists of a a hollow tube for evacuating the smoke, a tubular housing including vortex means for creating a vortex at an entrance end of the tubular housing, and an exit end of the tubular housing connected to one end of the hollow tube, another end of the hollow tube being connected to a suction means for creating suction to remove the smoke from the air near the electrosurgical device.
