Abstract
A cryosurgical apparatus with a temperature regulator. For better therapeutic success, it is desirable to set the temperature applied to a cryosurgical instrument as exactly as possible. Conventional apparatuses have corresponding temperature sensors allowing the regulation of the cooling power in the cryosurgical instrument such that the cooling power corresponds to a predefined value. However, the dimensions of some temperature sensors prevent them from being provided within a cryoprobe. Furthermore, suitable temperature sensors are expensive and have low durability. This problem is solved by the disclosed temperature regulator for regulating the temperature of a cryoprobe, which supplies an at least partly liquid refrigerant at a first pressure to an evaporation region such that the coolant evaporates at least temporarily under the presence of a second pressure for cooling a cooling portion of the cryoprobe. A pressure setting means that sets at least the second pressure is also provided.
