Abstract:
An electrosurgical electrode comprises a generally L-shaped metal member comprising an electrically-insulated, generally straight shank part for mounting in a standard electrosurgical handpiece, and a generally curved part divided into first, second, third, and fourth sections, the second, third, and fourth of which are electrically-insulating and the first of which is bare and terminates in a pointed end. The second and third sections are covered with a thin electrically-insulating coating, whereas the fourth section, closest to the shank, is covered with a thicker electrically-insulating coating. The first, second, and third sections are dimensioned and constructed so as to enable the surgeon to know fairly precisely the depth of the first section in tissue targeted for radiofrequency thermal ablation. An important application is volumetric shrinkage of tongue base tissue, for example, for treating sleep disordered breathing.
