Abstract:
1. An electrosurgical suction coagulator, comprising: a housing having proximal and distal ends and a substantially malleable elongated tube like shaft extending longitudinally from the distal end thereof, the substantially malleable elongated tube-like shaft including: a tube-like dielectric sheath; a tube-like conductor disposed coaxially through the tube-like dielectric sheath and configured to operably couple to a source of electrosurgical energy, the tube-like conductor having at a distal end thereof at least one tube aspiration port defined therein, the tube-like conductor being adapted at a proximal end thereof to operably couple to a source of aspiration suction; an electrode tip disposed distal to the tube-like conductor and separated from the tube-like conductor by an isolator configured to thermally insulate the electrode tip from the tube-like conductor, the electrode tip in electrical communication with the tube-like conductor through the isolator, wherein the electrode tip and isolator further define a tip aspiration port that is in fluid communication with the tube aspiration port; and a generally cylindrical insulating region coaxially disposed between the tube-like sheath and the tube-like conductor, wherein the cylindrical insulating region includes at least one thermal insulator.
