ABSTRACT OF THE DISCLOSURE Apparatus including a frame; a generally elongated endoscopic portion connected to the frame and extending distally therefrom; a pair of jaw members cooperating with a distal end of the endoscopic portion, the jaw members disposed in opposing relation and being relatively pivotal about a common point between at least an open position and a closed position, each of the jaw members including: a distal portion including a first surface adapted for engaging tissue, the first surface having a recessed portion formed therein and a second surface being of smooth continuous construction; a proximal portion including pivot means adapted to cooperate with the inner rod member; and an intermediate portion being recessed relative to the distal portion such that upon contact of the jaw members, the intermediate portions arespaced apart from each other. The apparatus may further comprise means for rotating the endoscopic portion. In a preferred embodiment, the apparatus is a unipolar electrosurgical biopsy forceps and is provided with conducting means attachable to the frame and in electrical communication with a conductive endoscopic portion for receiving an electrical current from an electrical source. The jaw members are also electrically conductive. Electrical insulating means may be selectively disposed on the instrument for insulating predetermined portions thereof from electrical energy.
