Laser surgery plume evacuator with aspirator

摘要

A portable laser surgery evacuator includes an aspirator contained in the same housing which is positionable in an operating room near a surgical site. Surgical plume is evacuated from the site by vacuum, filtered through moisture, purifying and particle filters, chemically deodorized, and exhausted in cleaned form into the operating room environment. Fluid containing liquid is aspirated by pumping to a collector bag hung on a hose of the evacuator. Gaseous plume components of the fluid are vented from the collector to the evacuator to be cleaned with the plume. The venting is provided by a hose joining the evacuator inlet hose at a Venturi like connection. The evacuator includes a symmetrical reversible charcoal filter having a moisture absorbing cellulose filter at each end. A disposable aspirator pump of the rotating impeller type mounts on a motor shaft extending through the housing and is restrained against rotation by fixed hooks against which the pump fittings are urged by the torque of the motor.
