The invention relates to a surgical resection device. A surgical organ resection device comprises a plurality of elongate electrodes (4) for insertion into organ tissue, the electrodes being capable of operating in a bipolar manner, and an input terminal for receiving a radio frequency drive signal for driving the elongate electrode, the plurality of elongate electrodes including two groups or more groups of elongate electrodes being arranged in a two-dimensional array. When the elongate electrodes are connected to a radio frequency generator and driven by appropriate radio frequency power, a tissue adjacent to the elongate electrodes is heated, the tissue heating causes vessel sealing, preventing blood loss during subsequent resection. The device may also be arranged such that, in use, subsets of the elongate electrodes are driven in turn.
