Advances in cryosurgical technology have further stimulated interest in the use of cryosurgery to treat different diseases, first and foremost malignancies. The effect of different temperature applications on the freeze-thawing process in vitro to evaluate modern cryosurgical techniques as a treatment option for diseases of different organs, primarily for malignant tumors, has not yet been investigated. The effect of freeze-thawing processes using temperatures of varying intensity, and the cryosurgical response of a solution of 1.5% of gelatine in water kept at a constant temperature of +30°C, and continuously stirred, are described in vitro in this study. The investigations were performed at temperatures of -40°C, -80°C, -120°C, and -180°C by means of two disc-shaped cryoprobes with diameter of 5 to 50 mm respectively, and a laparoscopic needle with a diameter of 10 mm.
