Abstract
A surgical instrument is provided for clamping and cutting during surgical procedures, particularly for use with tissues of varying thicknesses. The instrument in a preferred embodiment compresses tissue between electrodes associated with jaws of the clamping device and applies electrosurgical energy to the tissue. The invention provides an expandable cutting element which is adapted to compensate for various thicknesses in tissue and contractible by providing a knife which can be contained within the jaws and expand as needed for thicker tissues. The cutting element is preferably actuated as or after the electrosurgical energy has been applied, to cut tissue engaged and treated by the jaw members.
