Abstract
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.
Claims20
An endoscopic forceps, comprising:
- a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough;
- an actuation mechanism operably associated with the endoscopic forceps;
- an end effector assembly operatively connected to a distal end of the shaft and having a pair of first and second jaw members at least one of which being movable relative to the other from an open position wherein the first and second jaw members are disposed in spaced relation relative to one another, to a clamping position wherein the first and second jaw members cooperate to grasp tissue therebetween;
- and
- a heat activated drive assembly operably coupled to the actuation mechanism, the heat activated drive assembly operably coupled to the at least one movable jaw member and configured to impart movement of the at least one movable jaw member when the actuation mechanism is activated.
