Apparatus for performing an electrosurgical procedure

摘要

A surgical instrument is provided and includes a housing having a shaft. An end effector assembly is operatively connected to a distal end of the shaft and has a pair of first and second jaw members one of which is movable with respect to the other. A heat activated drive assembly operably couples to an actuation mechanism that is operably associated with the forceps and configured to supply thermal energy to the heat activated drive assembly. The heat activated drive assembly operably coupled to movable jaw member and configured to impart movement of the movable jaw member when the actuation mechanism is activated.
