1. A smoke evacuation pencil, comprising:
a hollow pencil body having a proximal end and a distal end;
an active electrode socket positioned in the distal end of the hollow pencil body, the active electrode socket securing an active electrode having a proximal end and a distal end, wherein the distal end of the active electrode extends beyond the distal end of the hollow pencil body; and
a one-piece rotatable, seamless internal channel disposed within the hollow pencil body, the one-piece rotatable, seamless internal channel having a length that extends from a proximal end hose fitting of the one-piece rotatable, seamless internal channel to a distal inlet of the one-piece rotatable, seamless internal channel, wherein the distal inlet is positioned proximally to, and independent of, the active electrode socket while overlapping the proximal end of the active electrode;
wherein the proximal end hose fitting of the one-piece rotatable, seamless internal channel is configured to be longitudinally aligned with, and attached to, a smoke evacuation hose, and wherein the one-piece rotatable, seamless internal channel is freely rotatable within the hollow pencil body thereby establishing a continuous suction flow pathway without a need for a seal to prevent suction loss.
