Abstract
A bipolar electrosurgical device for coagulating and cutting tissue has an elongated tubular member from which a bipolar tissue cutting forceps and cutting instrument extends at the distal end. The cutting instrument is connected to a moveable rod extending through the lumen of the tubular member. A first and second conductor pair extend in spaced apart parallel arrangement to allow the cutting instrument and its moveable rod to extend therebetween. The first and second conductor pairs are operatively connected to the forceps jaws. A moveable guide member is disposed within the lumen of the elongated tubular member and has means for selectively engaging the first and second conductor pairs for closing and opening jaws of the forceps. The forceps jaws have a slot for receiving the cutting instrument therebetween. A handle member is fixed to the proximal end of the first tubular member. The handle member includes means for imparting translational longitudinal reciprocal motion to the guide member and the cutting instrument for a coagulating and cutting procedure. The cutting instrument may have one cutting edge on the leading edge or a cutting edge on both the leading and trailing edge.
