ELECTROSURGICAL PENCIL WITH SMOKE EVACUATION AND ELECTRODE VISUALIZATION
Abstract:
An electrosurgical pencil includes a handle housing defining a fluid lumen and a central longitudinal axis. A nozzle defines a fluid lumen in fluid communication with the fluid lumen defined by the handle housing for evacuating fluid from a surgical site. The nozzle includes a slot configured to receive a nub protruding from the distal end portion of the handle housing to releasably couple the nozzle to the handle housing. An electrode configured to deliver electrosurgical energy to tissue has a proximal portion coupled to the handle housing and a distal portion extending through the fluid lumen defined by the nozzle. At least a portion of the electrode extends distally from a distal end of the nozzle. The electrode defines a central longitudinal axis offset from the central longitudinal axis defined by the handle housing.
