Patent ID: 8182480

Claim:
An electrosurgical suction coagulator, comprising: 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 defining a cavity and including: a tube-like outer wall having a tube-like dielectric sheath at least partially disposed thereon; a tube-like electrode disposed coaxially through said cavity and configured to operably couple to a source of electrosurgical energy, wherein a distal end of the tube-like electrode protrudes at least partially from a distal end of the tube-like outer wall, the tube-like electrode having at the distal end thereof at least one aspiration port defined therein, the tube-like electrode being adapted at the proximal end thereof to operably couple to a source of suction; and a sealable vacuum space 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.
