Summary

A novel, flexible, long slender cryoprobe with a vacuum insulation layer of outermost diameter 3.1 mm and length 1 meter has been developed for cryosurgery of malignancy and cancers. The tip of the cryoprobe was cooled by liquid nitrogen. The boiling heat transfer characteristics were investigated in detail. The effects of the mass flow rate of liquid nitrogen, jet mouth-to-tip distance, shape of the probe tip, and surface roughness on boiling heat transfer were examined experimentally for cryosurgery.
