1. An adaptor comprising:

  • an adaptor input which at least substantially mates with a monopolar output of an electrosurgical generator;

    a second adaptor input which at least substantially mates with a monopolar return input of the electrosurgical generator;

    two adaptor outputs which at least substantially mate with a bipolar device piece;

    an electrical component connected with the adaptor such that when the electrosurgical generator powers the bipolar device piece through the adaptor output;

    the bipolar device piece receives an unaltered monopolar output RF signal produced from the monopolar output of the electrosurgical generator; and

    the electrosurgical generator observes a bipolar return signal from the bipolar device piece at the monopolar return input, wherein the bipolar return signal from the bipolar device piece is configured to fall within a programmed predetermined safety impedance range of the electrosurgical generator such that the bipolar return signal is substantially the same as a monopolar return signal observed by the electrosurgical generator when the electrosurgical generator powers a monopolar device piece from the monopolar output and the monopolar return signal passes from the monopolar device piece to the monopolar return input of the electrosurgical generator through a return pad.
