Abstract:
An electrosurgical instrument has dual zone smoke evacuation for providing efficient capture and evacuation of smoke generated during an electrosurgical procedure. A hand piece with a proximal and a distal end is coupled to a front piece having a distal opening leading into an interior conduit. An extendable section is at least partially disposed within the interior conduit and extends distally out of the distal opening of the front piece. The extendable section is selectively translatable within the interior conduit. A negative pressure source enables the capture and evacuation of smoke through both the extendable section and the interior conduit.
