Power level control apparatus for electrosurgical generators
First Claim
1. An electrosurgical generator system, said system comprising:
- an electrosurgical generator for producing electrosurgical power,an electrosurgical handpiece including an active electrode for receiving said electrosurgical power from said generator, a first coagulation mode switch connected to said electrosurgical generator, for, when in an activated state, providing a coagulation mode of operation of said generator, and a first cut mode switch connected to said electrosurgical generator for, when in an activated state, providing a cut mode of operation of said generator, anda foot activated switch device including a second coagulation mode switch connected to said electrosurgical generator for, when in an activated state, providing said coagulation mode of operation of said generator and a second cut mode switch connected to said electrosurgical generator for, when in an activated state, providing said cut mode of operation of said generator,said generator including signal processing means connected to said handpiece and said foot activated switch device for monitoring for the activated state of at least one switch of said first and second coagulation mode switches and said first and second cut mode switches so as to detect any activation of the at least one switch being monitored, and for, responsive to at least two successive activations of only a single switch of the at least one switch being monitored, providing control of the power produced by said electrosurgical generator by further activation of said single switch.

Abstract
An electrosurgical generator system includes an electrosurgical handpiece including an active electrode for receiving electrosurgical power from a generator, and cut and coagulation mode switches and a foot activated switch device also including cut and coagulation mode switches. A signal processor associated with the generator and connected to the handpiece and foot activated switch device monitors the states of the cut and coagulation mode switches so as to detect activation of any of these switches and, responsive to two successive activations of a single switch of the switches being monitored, provides control of the power produced by the electrosurgical generator by further activation of the single switch.
