ABSTRACT:
The invention proposes a cryoprobe for surgical and other treatments. The cryoprobe comprises a bellow-wise section that performs displacement of a distal cryotip forwards with elevation of 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 to enlarge significantly a frozen volume of the treated tissue for same operation temperature and the outer diameter of the cryoprobe.
