A bipolar electrosurgical instrument for cutting and
coagulating tissue comprising:
(a) first and second metal blades each having a
cutting edge and shearing surface, said first metal blade
supporting an insulative layer on a surface other than the
cutting edge and shearing surface thereof and an electrically
conductive electrode member on the insulative layer;
(b) means for pivotally joining said first and
second blades together with their respective shearing surfaces
facing one another;
(c) means coupled to at least one of said first and
second blades for imparting a scissors-like movement relative
