Abstract

Smoke evacuation apparatus designed to provide safe and efficient filtration and evacuation of smoke plume generated by laser-surgical, electrosurgical, radiosurgical, and electrocautery devices. To ensure capture and removal of the smoke plume, several stages of filtration processes, including a first micro-pre-filter to filter out the most particles and harmful elements at this stage followed by passage of the smoke plume through a main vacuum suction unit and filter to filter out the remaining particles and any odors, are employed. Preferably, the main filter comprises fine charcoal through which the air flows radially which helps remove the odors. In a preferred embodiment, means are provided to monitor the degree of pollution of the main filter to warn users when it is desirable or necessary to replace the main filter. In addition, means are provided to ensure reasonably constant air mass flow to protect against significant clogging of the system which could result in undesirable passage of harmful particles into the environment.
