摘要

Disclosed is apparatus (100) for the reduction or removal of smoke particles suspended in a local atmosphere A and resulting from a surgical procedure, the apparatus including or comprising two electrodes (140) and (150) each in electrical communication with or being electrically connectable to opposite poles of a source of high voltage dc electricity. A first of the electrodes (140) may be electrically connectable to a patient P. and a second (150) may be positionable within or adjacent a patient such that the two electrodes, when in communication with opposite poles of said high voltage, ionise said particles in use, for attracting said particles toward the patient or toward the second of the electrodes.
