Abstract
Electrosurgical cauterizing apparatus has a radio frequency generator with a power oscillator which generates a bipolar cauterizing output signal for application to a pair of cauterizing electrodes. The oscillator carrier frequency varies according to the load resistance represented by tissue being cauterized and this variation is used to monitor the tissue resistance as cauterization progresses. The apparatus generates a cauterisation termination signal according to progress of the tissue resistance on a resistance versus time curve characteristic of the tissue cauterization process.
