Abstract: PROBLEM TO BE SOLVED: To enable to start and stop the flow of inactive gas to a standard electric surgery pencil during an electrical surgery operation. SOLUTION: By operating an electric surgery energy request button of an electric surgery pencil 13, the flow of electric surgery energy from an electric surgery generator 11 and the flow of inactive gas from the flow control valve of an gaseous surgery unit 26 are supplied at a time. An automatic switch 16 connected to an energy source 14 is opened and closed by the energy flow when a surgeon operates the electric surgery energy request button, the flow control valve of the gaseous surgery unit 26 is activated to control the inactive gas to the pencil, and the electric surgery generator 11 is activated and energy is supplied to the pencil.

Abstract: A circuit 10 for concurrent activation of a gas surgical unit 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 automatic switch 16 opening and closing in response to operation of the button 12 to control the valve and the generator. There may be separate cutting and coagulation buttons 17 and 18 on the pencil 13 connected to respective relays in the circuit 10. The gas surgical unit 26 may supply argon and be connected to the foot switch control terminal of the electrosurgical generator 11. The automatic switch 16 may be battery powered.

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.
