SUCTION COAGULATOR

摘要

An electrosurgical suction coagulator includes a housing having proximal and distal ends and an elongated tube-like shaft extending longitudinally from the distal end of the housing. The elongated tube-like shaft includes a tube-like dielectric sheath, a tube-like conductor, and an external insulator. The tube-like conductor is disposed coaxially through the tube-like dielectric sheath. The distal end of the tube-like conductor protrudes at least partially from the distal end of the tube-like dielectric sheath. The external insulator is disposed coaxially around the tube-like dielectric sheath. The external insulator extends from about the proximal end of the dielectric sheath to about the distal end of the dielectric sheath.

1. An electrosurgical suction coagulator, comprising:
a housing having proximal and distal ends; and an elongated tube-like shaft extending longitudinally from the distal end of the housing, the 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, wherein a distal end of the tube-like conductor protrudes at least partially from a distal end of the tube-like dielectric sheath, the tube-like conductor having at the distal end thereof at least one aspiration port defined therein, the tube-like conductor adapted at a proximal end thereof to operably couple to a source of aspiration suction; andan external insulator disposed coaxially around the tube-like dielectric sheath.
