Abstract: An electrosurgical generator is equipped with a smoke evacuator which becomes active upon acting either on the foot pedal (16) or on the activation button on the hand piece (32). Evacuation however only takes place when the suction motor (29a) is activated by a trigger device (14) via other components (25, 37, 27) whenever HF current begins to flow. The rate of suction is determined by a smoke detector (42) placed on the smoke passage (30). A similar system can be used for total or partial removal of liquids from the operation site.

Abstract: An electrical circuit system (1) which provides electrical energy to a surgical apparatus having ultrasonic fragmentation, aspiration and electrosurgical coagulation capabilities, which system also includes an impedance sensing network (10) and automatic feedback power output control to reduce RF power output as load impedance increases, thereby reducing RF leakage current.
