The basic examination of a handpiece treatment system combining cryosurgery with hyperthermia treatment

Abstract

The handpiece type device for the cooling and warming operation has been developed in our study.The system performance has been also evaluated. The treatment system consists of the handpiece Peltier device was attached to and an injected coolant and a stabilized DC power supply. In this study, the effect of various coolants on the temperature of the operation side of Peltier device was evaluated.As a result of experiment, The minimum temperature of the operation side using an ammonium nitrate mixture as coolant was lowest in thats of other coolants. But, this result suggests that the more enhancement of refrigeration performance of the system would need. The system improvement and the evaluation of the system performance will be performed in the future.
