摘要：The invention relates to a cryogenic system which is provided for performing cryosurgical interventions in the area of human and veterinary medicine, especially for treating tumors. The inventive system is comprised of a cryostat (1) and of a connecting device (8) which is located between coaxial cryogenic lines for the direct flow (9) and return flow (10) of the cryogenic medium and which is provided for connecting a cryoinstrument (17) to a cryo-attachment (13). The electromagnetic valve (11) is located in the immediate proximity of the connecting device (8). A regulating device (18) is provided for controlling the electromagnetic valves (2, 3, 4 and 7) as well as the heating element (12), and regulates the excess pressure of the cryogenic medium in the cryostat (1) to an accuracy of ± 0,1x105 Pa. The bottle neck (23) of the cryostat (1) is made of a material exhibiting a low level of thermal conductivity. In order to effect a precise sealing between said coaxial lines (9) and (10), truncated connecting elements (30, 31) which correspond with one another are placed inside line (10), and truncated connecting elements (34, 35) which also correspond with one another are placed inside line (9). In addition, an electric line (36) is provided for an electrical connection or interruption between both lines (9, 10).
