| titleOfInvention | Circuit and method for argon activation |
| abstract | A circuit (10) for concurrent activation of a gas surgical unit (26) flow control valve (15) and an electrosurgical generator (11) upon the surgeon's operation of an electrosurgical energy request button (12) on an electrosurgical pencil (13) has an energy source (14) coupled to the electrosurgical pencil (13) for supplying power in the circuit (10) to provide simultaneous flow of electrosurgical energy from theelectrosurgical generator (11) and flow of inert gas from a gas surgical unit (26) flow control valve (15). The energy source (14) current flow directly responds to the operation of the energy request button by the surgeon. An automatic switch (16)connected to the energy source (14) receives the flow of current upon the operation of the energy request button by the surgeon for opening or closing when the energy request button is opened or closed. The switch connects to the gas surgical unit (26) flow control valve (15) operating it to control inert gas to the pencil. The switch connects to the electrosurgical generator (11) operating it and delivering energy to the pencil. The circuit (10) responds if the surgeon uses the electrosurgical energy request button (12) to obtain a cut or coagulation waveform. A first relay (20) in series with a cut button and a second relay (21) in series with the coagulation energy request button have coils and normally open switch contacts connected to the flow control valve (15) and the electrosurgical generator (11) so current flow from the source magnetically closes the contacts. A method has steps of coupling the source to the switch to supply power for opening and closing the switch in sync with the button and operating the gas surgical unit (26) flow control valve (15) and the electrosurgical generator (11) with the switch. Supplying energy pencil is a step. Operating either the cut or coagulation on the pencil button is a step. |
