A cryosurgical probe (cryoprobe) (100) for ablation of a superficial tissue. The cryoprobe operation is preferably based on combination of two freezing effects: a) heat transfer from a liquid, gaseous or aerosolized cryogen, which is delivered from openings (105) in the cryoprobe tip immediately on the surface of the treated tissue, and b) heat transfer from needle (s) (106) installed on the outer surface of the cryotip. This needle (or needles) is constructed from material with high thermal conductivity. In addition, the outer surface of the cryotip may be provided with spacers, which limit the depth of penetration of the needle (s) into the tissue.
