Abstract

The symmetrical impedance bridge, will be suggested to yield consistent and reliable results for measuring tissue damage during electrosurgical ablation. The methods that were identified as potentially viable for ablation detection were force and displacement measurements between the electrode tip and tissue surface. These were found to correlate tissue damage due to a high degree of variability in charge density caused by contact area variation. Another method, temperature measurement via thermistors, will be found to have a response time and a non-contact method will be examined with the size constraints. The last method will be to measure and correlate changes in the power output of the ESU to tissue damage. This method will be practically examined to measure and correlate to tissue damage due to ESU power output modulation. The changes in the tissue's electrical properties can be measured directly far more easily than measuring the power output. Correlation with tissue damage tended to be strong with an error range below what can be detectable by the human eye. But the high degree of variability in the mechanical properties of tissue makes the use of force and displacement measurements difficult to implement as part of a control method for ablation control.
