Abstract
The present invention is a electrosurgical device having an elongated tubular member with a cutting and coagulating arrangement at its distal end and a handle at its proximal end. The coagulating and cutting instrument consists of two electrode jaw members with cutting blade extending therebetween. The cutting blade is connected to a movable rod extending through the lumen of the tubular member. A first and second conductor pair extend through the lumen of the tubular member in a spaced apart parallel arrangement with the cutting instrument and its movable rod extending therebetween. The first and second conductor pairs form the forceps jaws. The forceps jaws have a slot for receiving the cutting instrument therebetween. The handle member affixed to the proximal end of the tubular member includes a selector switch used for selecting a mode of movement of the jaws so that either unidirectional mode or a bidirectional mode can be selected. The device further includes a release connected to the selector means for restoring bidirectional movement of the jaw mechanism if the unidirectional mode had earlier been selected.
