Abstract

An electrosurgical unit (10) which combines an electrosurgical power generator and a filtered smoke removal system into a single compact instrument comprising an electrosurgical generator module (12) and a smoke removal module (14). The electros-urgical generator module (12) is designed specifically to accommodate an electrosurgical tool (73) during LEEP or LLETZ proce-dures. The electrosurgical generator module (12) provides power to the electrosurgical tool (78) at a predetermined level. The smoke removal module (14) removes and filters smoke from the site of the electrosurgery. A switching circuitry (60) activates the smoke removal module (14) substantially simultaneous to the activation of the electrosurgical tool (78) so that the smoke removal module (14) is activated automatically whenever the electrosurgical tool is activated. The switching circuitry (60) also delays the deactivation of the smoke removal module (14) after the electrosurgical tool (78) has been deactivated. The electrosurgical tool (78) alternatively can be connected, concentrically or in parallel, to a smoke evacuation tube (80) in communication with the smoke removal module (14).
