1. An electrosurgical device comprising:
a housing defining an interior bore;
a shaft extending distally from the interior bore of the housing, wherein the shaft is rotatable relative to the housing, wherein the shaft has a longitudinal axis extending between a proximal end of the shaft and a distal end of the shaft;
a smoke evacuation channel in an inner cavity of the shaft, wherein the smoke evacuation channel is rotationally fixed relative to the housing; and
an electrosurgical electrode extending distally from the distal end of the shaft such that (i) the shaft conducts electrosurgical energy to the electrosurgical electrode, and (ii) rotation of the shaft relative to the housing causes corresponding rotation of the electrosurgical electrode relative to the housing.
