Patent abstract
An electrosurgical pencil includes an adjustable-length suction tube which surrounds a stationary electrode to evacuate smoke and electrosurgical byproducts from a surgical site. An electrode anchor unit is located within the interior of the suction tube to allow relative movement of the suction tube relative to a stationarily-retained electrode, and to receive and connect to different lengths of the electrodes. Adjusting the length of the suction tube relative to the different lengths of the electrode achieves effective evacuation, among other things.
