Abstract
An electrosurgical unit which combines an electrosurgical power generator and a filtered smoke removal system into a single compact instrument comprising an electrosurgical generator module and a smoke removal module. The electrosurgical generator module is designed specifically to accommodate an electrosurgical tool during LEEP or LLETZ procedures. The electrosurgical generator module provides power to the electrosurgical tool at a predetermined level. The smoke removal module removes and filters smoke from the site of the electrosurgery. A switching circuitry activates the smoke removal module substantially simultaneous to the activation of the electrosurgical tool so that the smoke removal module is activated automatically whenever the electrosurgical tool is activated. The switching circuitry also delays the deactivation of the smoke removal module for a predetermined amount of time after the electrosurgical tool has been deactivated. The electrosurgical tool alternatively can be connected, concentrically or in parallel, to a smoke evacuation tube in communication with the smoke removal module.
