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.

A self-contained air enhancement system for removing contaminants from a laser plume produced at a surgical site during a medical procedure, said system comprising: a housing; an inlet tube for removing the laser plume from the surgical site; a suction canister secured to said housing and being in communication with said inlet tube for removing liquid components of the contaminants from the laser plume; a prefilter located in said housing and being in communication with said suction canister for removing particulates from the laser plume; a filter canister located in said housing and being in communication with said suction canister, said filter canister housing a primary filter capable of removing substantially all of the remaining fine particulates from the laser plume and containing charcoal for removing the odor from the laser plume to produce filtered air; means located in said housing downstream of said filter canister for creating suction to pull the laser plume in sequence through said inlet tube, said suction canister, said prefilter, and said primary filter; outlet means in said housing for expelling said filtered air from said housing; inlet means located in said housing for providing ambient air for cooling said means for creating suction; and means for shielding the laser plume within the housing from cross-contamination of the ambient air for cooling said means for creating suction.
