Résumé

Cryosurgery is a well-established technique that can offer considerable advantages to the patient. To date cryosurgical instruments have predominantly employed either liquid cryogens or the J-T expansion of high-pressure gases in an open cycle. The handling of cryogens or high-pressure gases in a surgical environment poses logistical problems. A two-stage vapour cycle cryosurgical system has been designed to use either R23 or R508B in the low temperature stage and R404A for precooling. This paper reports the results of trials of the prototype using R23 in the low-temperature stage. The cooling performance achieved equals that of existing, open cycle, cryosurgical systems.
