Bipolar assisted diathermy

Bipolar diathermy is an electrosurgery technique that functions by passing an alternating current at a high frequency through a pair of forceps to cut the tissue and coagulate the blood vessels. 

In bipolar diathermy, the two electrodes are found on the instrument itself. The bipolar arrangement negates the need for a dispersive electrode, instead, a pair of similar-sized electrodes are used in tandem. The current is then passed between the electrodes.
