摘要:
Apparatus (100) and method are disclosed for removing or reducing the number of particles in an enclosed atmosphere during intracorporeal procedures. The apparatus comprises a housing (180) adapted to be placed against the body on which a procedure is to be formed, a first electrode (140) external to the housing for contacting the body, an elongated electrically insulated probe (130) extending from the housing (180) and being insertable into an intracorporeal body cavity (C) in which a procedure is to be performed, a second electrode (150) at the free end of the probe, and circuit means (110) for generating voltage between said first and second electrodes. The method comprises applying a voltage between the electrodes sufficient to cause local ionization of particles within the body cavity such that they migrate away from the second electrode, thereby removing or reducing the number of particles generated during the procedure from the enclosed atmosphere at or around the site of the procedure.
