Résumé

To conveniently accommodate to the need for combined cryosurgical and hyperthermia treatments, a hand-held cryoprobe system for general-purpose thermotherapy (including both cryosurgery and hyperthermia) has been developed using multi-stage Peltier thermoelectric coolers/heaters in this study. The advantages of the present cryosurgical/hyperthermia system consist of hand-held, fully electrically-controlled, no movement of cooling medium and refrigerant-free. To test the performance of the new system, a series of experiments are respectively performed in air and tissue phantom. The results indicate that the temperature at the probe tip of the new system can easily reach -60°C during freezing and above 60°C during heating. It suggests that the new cryosurgical/hyperthermia system would allow reliable combined cryosurgery and hyperthermia, especially when cryo-refrigerants are not available.
