1. An apparatus for cutting and cauterizing tissue during surgery while minimizing electrical and thermal contact of said apparatus with surrounding tissue, said apparatus comprising:

  • a pair of opposing electrically conductive cutting blades pivotally connected to allow for shearing action of any tissue confined between opposed cutting edges of said cutting blades, said blades having blunted tips, said pair of opposing cutting blades being entirely covered with an electrically and thermally insulative material except at said blunted tips;

    wherein each of said cutting blades comprises an inner surface, an outer surface, an outer edge, the cutting edge and a distal edge surface, said blunted tip comprising said distal edge surface and forming a portion of said inner surface, said outer surface, said outer edge, and said cutting edge;

    wherein each of said cutting blades is covered with an electrically and thermally insulative material except on said inner surface closely adjacent said cutting edge or except on said outer surface closely adjacent said cutting edge; and

    a power source coupled to at least one of said pair of opposing cutting blades for electrically and thermally energizing at least one of said pair of blades.
