Measurement of Characteristics of Cryoprobes under Different Operation Modes

Abstract

Experimental time curves of temperature distribution over the length of the working surface of a minimally invasive cryoprobe were measured for various modes of operation (cooling or heating). The cooldown time was determined. A custom-built experimental installation allowed different types of minimally invasive cryoprobes to be tested. The results of the experiments can be used in planning cryosurgery using commercially available cryoprobes, as well as for testing the efficiency of newly developed cryosurgical instruments.
