FIELD: medicinal equipment, neurosurgery, urology, gynecology, ophthalmology. SUBSTANCE: device consists of heat exchanger with dry ice and two tanks for cold carrier, evaporator tank, normally opened vent, probe with cooling chamber at its end and elastic reservoir. Cryoprobe cooling is performed by closing a vent. Moreover, cold carrier under gas pressure from evaporator tank is passed through flexible tube system and cooling chamber. Different cooling volumes are achieved by applying cryoprobes that have different volumes of cooling chambers. EFFECT: simple and cheap construction that is reliable and electrosafe for no mechanic constructions with electrocontrol linkage are used. |
