Abstract
An electrode sealing assembly for use with an electrosurgical instrument for sealing tissue includes first and second jaw members which are movable from a first position in spaced relation relative to one another to at least one second position for grasping tissue. The jaw members include electrically conductive sealing plates designed to selectively transmit electrosurgical energy to tissue disposed between the sealing plates. The jaw members also include a thermoelectric cooling plate having a first surface in direct contact with an outer surface of the sealing plate. The thermoelectric cooling plate includes first and second electrical connections on opposite sides of the jaw member. The first connection is configured to selectively transmit a first electrical potential and the second connection is configured to selectively transmit a second electrical potential such that heat generated by the sealing plates is transferred away from the tissue via the thermoelectric cooling plate.
