1. An electrosurgical instrument for sequentially cutting and coagulating tissue, the instrument comprising:

  • a) a cutting electrode loop connectible to a first power source capable of delivering a first power signal sufficient to cut tissue;

    b) a coagulation electrode loop connectible to a second power source capable of delivering a second power signal sufficient to coagulate tissue; and

    c) a substantially smooth-walled electrical insulator extending from said cutting electrode loop and toward said coagulating electrode loop such that in use, said electrical insulator forms a smooth bridge between said electrodes and maintains said electrodes in spaced relationship to each other such that the coagulating electrode can immediately follow the cutting electrode during a single movement of the instrument through tissue.
