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, ionize said particles in use, for attracting said particles toward the patient or toward the second of the electrodes.各々が高電圧直流電源の反対極に電気的に連通し又は電気的に接続可能な２つの電極（１４０）及び（１５０）を含み、外科的処置に起因し局所的な大気Ａ中で保留される煙粒子を削減又は除去する装置（１００）が開示される。第１の電極（１４０）は患者Ｐに電気的に接続可能であり、第２の電極（１５０）は患者の内部に又は隣接して配置可能であり、２つの電極は、使用時に高電圧の反対極と連通する場合に、粒子を患者または第２の電極へ引きつけるために、粒子をイオン化する。【選択図】図１
