ABSTRACT:
Surgical apparatus for bipolar diathermy has a radio frequency generator connectible to a cutting assembly which includes a support structure having a pair of electrical supply conductors and, mounted at the distal end of the support assembly, a tissue cutting head. The cutting head comprises a loop of material which is electrically conducting and has a negative temperature coefficient (NTC) of resistance, such as silicon carbide. In operation, radio frequency power from the generator causes heating of the loop to a temperature at which its resistivity rises to level which exceeds that of living tissue with the result that diathermy currents pass through the tissue. Also disclosed is a pair of forceps with electrodes made of NTC material, for cauterization.
