    摘要: A device, system and method for controlling the temperature differential between the medium within the cryosurgical instrument and the external temperature of the shaft, apart from at the cryotip itself, uses a fluid medium supplied within an internal space between the shaft and an intermediate lumen positioned between the shaft and a central feeding lumen of the cryosurgical instrument. The temperature of the fluid medium is controlled to provide control of the temperature differential.

    摘要: A cryosurgical instrument features a cryogen in liquid or liquid-gaseous (mist) form being supplied by a feeding lumen into the internal space of a cryotip at the distal end of the cryosurgical instrument. The distal section of the feeding lumen is helically coiled, so that an outer diameter of the helically coiled distal section fits an inner diameter of a cylindrical envelope of said cryotip, and said helically coiled distal section and said cylindrical envelope are in thermal contact.

    摘要: A cryoprobe for surgical and other treatments. The cryoprobe comprises an expandable section that performs displacement of a distal cryotip forwards when there is elevation of the operation pressure in the interior of the cryoprobe. Needle-wise metal elements are installed on the external side of the cryotip. These needle-wise elements are deflecting outwards by a deflecting member fastened on the distal edge of an external shaft of the cryoprobe. This allows a significant enlargement of the frozen volume of the treated tissue with the same operation temperature and the outer diameter of the cryoprobe. In another embodiment, the needle elements are formed in a displaceable metal sheath and a distal section of a cryotip and/or special protrusions on this distal section act as the deflecting member.
