Residual heat of ablative surgical devices underestimated: methods to quantify and prevent potential side effects (Conference Presentation)

Paper Abstract

In surgery, the tips of energy delivery devices heat up far above 100 C. In this study, the typical thermal relaxation time of the tips after activation were measured using a thermal camera. The temperatures of the tips stayed over 60 C for tens of seconds. When touching nearby tissue for a few seconds, unintended thermal damage can be induced especially during endoscopic procedures where the space is narrow. Using water drops as irrigation, ambient temperatures were reached within several seconds. Surgeons should be aware of the residual heat of ablative devices.
