1. An electrosurgical device, comprising:
a housing defining an interior bore;
a shaft coupled to the housing, wherein the shaft has a longitudinal axis extending from a proximal end of the shaft to a distal end of the shaft; and
an electrosurgical electrode coupled to the shaft,
wherein the shaft comprises:
a shaft wall having an inner surface and an outer surface, wherein the inner surface of the shaft wall defines a smoke evacuation channel that extends from the distal end of the shaft to the proximal end of the shaft, and
an electrode receptacle that couples the electrosurgical electrode to the shaft, wherein the electrode receptacle extends across the smoke evacuation channel in a direction that is transverse to the longitudinal axis of the shaft such that electrode receptacle partitions the smoke evacuation channel into a plurality of smoke inlets at the distal end of the shaft,
wherein the plurality of smoke inlets consists of a first smoke inlet and a second smoke inlet, wherein the first smoke inlet is defined by a first side of the electrode receptacle and a first half of the inner surface of the shaft wall, and
wherein the second smoke inlet is defined by a second side of the electrode receptacle and a second half of the inner surface of the shaft wall,
wherein the electrode receptacle defines an aperture and a proximal portion of the electrosurgical electrode is received in the aperture of the electrode receptacle.
