摘要：
An electrosurgical smoke evacuation pencil includes a handle housing having a proximal end portion and a distal end portion, the handle housing defining a first lumen therethrough. The electrosurgical pencil also includes a nozzle disposed within the first lumen and defining a second lumen, the nozzle being movable relative to and within the handle housing and extending proximally past the proximal end portion of the handle housing. The electrosurgical pencil may further include a swivel connector coupled to the distal end portion of the handle housing, the swivel connector configured to couple to a suction source. The electrosurgical pencil includes a hub assembly securedly disposed within the second lumen, the hub assembly including a conductive tube configured to couple to a source of electrosurgical energy, and an electrode slidably disposed within the conductive tube, the electrode being movable relative to and within the conductive tube.
