1. An articulating electrosurgical instrument, comprising:
a housing having an elongated shaft extending therefrom;
a wrist assembly operably supported to a distal end of the elongated shaft and configured to support an end effector assembly at distal end thereof, the wrist assembly including:
a proximal link operably coupled to the distal end of the elongated shaft;
a distal link operably coupled to the end effector assembly; and
a central link operably coupled between the proximal link and the distal link;
a transition lumen configured to be received within at least the distal link, central link and proximal link, the transition lumen including a helical passageway defined therein configured to guide a blade rod therethrough for operable engagement with a blade disposed within the end effector assembly.
