Cryosurgery has been performed by the contact technique using liquid nitrogen as refrigerant Therefore it has some problems, e g excess freezing of an organ In this study, we have proposed a new cryosurgical system that enables higher precision than the conventional cryosurgery unit The lowest cooling temperature of this new cryosurgical system was about - 50℃ when its cooling liquid was about -20℃ In order to obtain the enough cell necrosis, it is necessary to optimize the low cooling temperature, freezing time and repetition frequency This new cryosurgical system makes it possible to control those conditions electrically These findings seem to be hopeful that the new surgical system can realized more effective cryosurgery
