Abstract
A combined smoke evacuation and filter apparatus adapted to receive and hold a surgical device which may produce smoke such as a cauterization pencil or a laser device, and which apparatus can be connected to a vacuum source. The apparatus includes a unitary holder formed of elastic material, a suction tube carrying the power line of the device, a tubular plastic back end piece connecting the holder to the suction tube, and a filter housing at an end of the suction tube. The filter housing contains a four stage filter and a casual liquid collector. The unitary holder has a cradle, a conically shaped portion, and an oval shaped lumen located below the cradle for carrying the smoke to the end piece. The tubular back end piece is provided with a retaining fork which bears against the proximal end of the device, the elastic holder being stretched when the parts are assembled.
