1. An electrosurgical device adapted to be connected to an electrical generator having active and return output terminals, said device being used to cut, coagulate or otherwise treat human tissue or the like, said device comprising:

  • an insulative electrode support means;

    a first electrode adapted for connection to said active output terminal;

    a second electrode adapted for connection to said return output terminal, said first and second electrodes being rigidly supported a fixed distance apart by said electrode support means, both said first and second electrodes being adapted for electrical connection to said tissue;

    means for respectively connecting said first and second electrodes to said active and return output terminals; and

    means for maintaining a separation between said first electrode and said tissue whenever said second electrode is in contact with said tissue and said first and second electrodes are connected to their respective output terminals to insure that a current arc is established between said first electrode and the tissue.
