Abstract
An articulating electrosurgical instrument includes a housing having an elongated shaft extending therefrom and 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 includes 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 is configured to be received within the distal link, central link and proximal link. The transition lumen includes a helical passageway defined therein configured to guide a blade rod therethrough for operable engagement with a blade disposed within the end effector assembly.
