ABSTRACT:
A smoke reducing device for use in minimally invasive surgery includes a housing having an inlet opening from an outlet opening. The housing is sized to fit through a trocar opening that leads to a body cavity. A filter is positioned within the housing between the inlet and outlet openings. An air flow generator is located within the housing and is positioned to draw air in through the inlet opening, pulled through the filter, and exhausted through the outlet opening to draw any smoke created during minimally invasive surgery through the filter. The smoke reducing device may form part of an electrocautery device such that smoke created during minimally invasive surgery can be filtered internally of the body cavity.
