Abstract

A surgical laser smoke evacuator, with in-line plasma devitalization of viral bio-entities and their capture system, comprising a medical ablation laser probe, co- axially disposed inside a plume aspirator carrying the airborne biological debris, from vaporized tissue past a viral deproteinization plasma generator onto a high efficiency particulate immobilization cartridge, is disclosed. These components, in combination, ensure that the assembly yields a virus-free exhaust that prevents cross-infection from the patient to the medical personnel. The diaphragm air pump replaces the conventional motor blower and vacuum pump, which have numerous particulate lodgment sites, and makes the apparatus of this patent, sufficiently compact and portable, so as not to require the usual operating room space. It also does not interfere with the free movement of medical personnel. The single hand-piece, functioning both as the ablation probe and aspirator, enables the surgeon to do without an attendant, who has to track synchronously the surgeon's movement during the invasive surgery, when conventional devices are used.
