Abstract
An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly operably coupled to the shaft includes a pair of first and second jaw members. One or both of the first and second jaw members is movable from an open configuration, to a clamping configuration. A knife blade assembly includes a knife blade translatable within the first and second jaw members. A knife blade lockout mechanism is in operative communication with the knife blade assembly and includes an elongated cam slot with a cam pin translatable therein from a distal end of the elongated cam slot corresponding to the knife blade lockout mechanism engaged with the knife blade assembly, to a proximal position corresponding to the knife blade lockout mechanism disengaged from the knife blade assembly.
