Abstract
A system for filtering the harmful particulates and liquids from a laser plume formed during surgical procedures. The laser plume may be passed through a suction canister to remove a liquid component from the laser plume. Thereafter, the laser plume is passed through a filter containing granular activated charcoal and a pleated filter to remove substantially all toxic elements and particulate matter in the laser plume. The system is self-contained and is configured such that the air from the laser plume is not cross-contaminated with either the ambient air in the room or the cooling air of the vacuum motor. The system also contains a pressure differential measuring device for indicating to the medical personnel when the filter of the present invention needs to be changed. Because of the unique configuration of the present invention, it is capable of running at increased suction levels while running at reduced noise levels as compared with conventional systems of this nature.
