Abstract
A surgical instrument for treating a tissue includes a handpiece and a tissue engaging portion arranged to be received by the handpiece. The tissue engaging portion includes first and second opposed jaw members having an open position and a closed position for engaging the tissue therebetween, where the first and second jaw members are arranged to receive surgical energy from a surgical generator. The tissue engaging portion further includes at least one cooling member spaced from at least one of the first and second jaw members, where the cooling member has an open position and a closed position for engaging the tissue. Positioning the jaw members in their closed position and applying surgical energy to the tissue allows for treatment of the tissue, and positioning the cooling member in its closed position provides at least one of a pressure gradient or a thermal gradient between the jaw members and the cooling member.
