Abstract
An electrosurgical suction coagulator includes a housing having proximal and distal ends and a substantially malleable elongated tube-like shaft extending longitudinally from a distal end thereof. The elongated tube-like shaft includes a tube-like outer wall having a tube-like dielectric sheath at least partially disposed thereon. A tube-like electrode is disposed coaxially through the tube-like outer wall and is configured to operably couple to a source of electrosurgical energy. A distal end of the tube-like electrode protrudes at least partially from a distal end of the tube-like outer wall and the tube-like electrode has at the distal end thereof at least one aspiration port defined therein. The tube-like electrode is adapted at the proximal end thereof to operably couple to a source of suction. A vacuum space is disposed concentrically between the tube-like electrode and the tube-like outer wall to impede the propagation of thermal energy along the tube-like shaft.
