A device for the mitigation of smoke and particulate suspended in an insufflated body cavity during minimally invasive surgical procedures consist of a single electrode manufactured within and/or on a trocar shaft, or any other laparoscopic or endoscopic instrument. The electrode is made of any electrically active material with many hundreds or thousands of extremely fine terminal points, such as carbon fiber or laser etched metals. The electrode is electrically connectable to the neutral (negative) pole of a source of high voltage direct current (DC) electricity and the positive pole of the same electrical source is grounded or terminally insulated. When the positive electrical pole is connected to the ground and the carbon fiber or etched metal electrode is connected the negative pole, anions stream from the terminal ends of the terminal ends attracting smoke, and any other particulate suspended in the cavity, causing them to precipitate out of the suspending gas and therefore clearing the surgeons view.
