Design and analysis of a Resistively Heated Surgival Probe.

Abstract

The thesis examines the use of heat for producing clinical lesions in tissue and presents the design and analysis of a resistively heated surgical probe. The probe temperature is accurately maintained and measured by using a Wheatstone bridge. The probe was embedded in an agar-water test medium and the temperature field emanating from the probe was measured using liquid crystal tapes. The experimental results compare within approximately 10% of a two-dimensional numerical solution. A one-dimensional theoretical model is developed and results are presented to show the relative effects of metabolism and blood flow on the temperature field. (Author)
