ABSTRACT:
A smoke evacuator and a system for surgical devices, such as electrocautery scalpels and laser surgical devices. Evacuator is geometrically designed to permit retrofit to existing electrocautery scalpels, and includes a radiused inlet to minimize noise and a stand off to prevent unintentional tissue suck down. The system optimizes suction flow rate, inlet diameter, and inlet distance so as to provide efficient evacuation while permitting good visibility. An automatic smoke evacuation system is also provided which switches the smoke evacuation on or off depending upon whether a current is sensed in the power cord to the electrosurgical device.
