A cutting coagulating bipolar electrosurgical forceps having a pair of jaws that can be moved from an opened to a closed disposition on tissue when grasping and coagulating. The jaws include a plurality of notched or opposed side edges thereof which define a plurality of tabs. The tabs on the first jaw member are offset relative to those of the second jaw member so that when the jaws are made to close, the tabs on the first jaw fall into the notches on the second jaw with the free ends of the tabs on corresponding side edges of each jaw member disposed collinearly relative to one another, but without making electrical contact between the pair of jaws.

[ What is claimed is:] [1.] In a bipolar electrosurgical instrument of the type including a handle member for supporting a pair of effectors and having a means for selectively applying a voltage across said pair of effectors, the improvement comprising:said pair of effectors each being a conductive metal having first and second side edges and being formed at an angle less than 180.degree. along a longitudinal axis between the first and second side edges, the side edges of the pair of effectors having a plurality of spaced, inwardly extending notches defining a plurality of tabs, the pair of effectors being supported by the handle member with the plurality of tabs on the side edges of one of the pair of effectors fit into the notches on the side edges of the other of the pair of effectors without the effectors contacting one another and with exposed end edges of the tabs on the first of the pair of effectors collinear with exposed end edges of the tabs on the side edges of the second of the pair of effectors.
