Thermal barrier for suction coagulator

摘要

An electrosurgical suction coagulator includes a housing having proximal and distal ends and a substantially malleable elongated tube-like shaft extending longitudinally front the distal end of the housing. The elongated tube-like shaft includes a tube-like dielectric sheath and a tube-like electrode disposed coaxially through the tube-lilce dielectric sheath. The tube-like electrode is configured to operably couple to a source of electrosurgical energy and a proximal end of the tube-like electrode is adapted to operably couple to a source of suction. The tube-like shaft also includes a thermally conductive member. The thermally conductive member is disposed concentrically about the tube-like shaft and at least partially along a longitudinal length of the tube-like shaft. The thermally conductive member is configured to increase a surface area of the tube-like shaft to dissipate thermal energy about the increased surface area.
