ABSTRACT:
An improved radio frequency cautery instrument comprising a radio frequency signal generator for supplying both monopolar and bipolar radio frequency signal outputs for medical applications. A control unit is interposed between the radio frequency outputs of the signal generator and the hand-held electrode assembly, and further interposed between a finger-operated switch on the electrode assembly and the power circuit of the signal generator, whereby the application of radio frequency energy to the electrode of the electrode assembly can be controlled by the user through manipulation of the finger-operated switch on the electrode assembly.
