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 a distal end of the shaft includes a pair of first and second jaw members one of which being movable from an open configuration for positioning tissue therebetween, to a clamping configuration for grasping tissue therebetween. A knife blade assembly includes a knife blade that is translatable within the first and second jaw members when the first and second jaw members are in the clamping configuration. The knife blade assembly includes a medial portion defining an opening therethrough having proximal and distal ends. A knife blade stop in operative communication with the knife blade assembly includes a pair of leading and trailing stops thereon that are configured to contact respective distal and proximal ends of the opening to limit translation of the knife blade assembly.
