The invention consists of a handpiece for a cryolipolysis treatment. The handpiece includes an almost dome-shaped wall with an elliptical base which delimits a seat into which can be inserted, at least partly, a part of the human body to be subjected to the treatment of cryolipolysis. The delimiting wall comprises a first opening, to the top of the handpiece, in correspondence of which, the latter is connectable to a suction device to create a depression inside the said seat. The delimiting wall also includes a second opening, at the base of the handpiece, to enable the insertion of the part of the human body, to be subjected to the treatment, in the above seat. The thickness of the delimiting wall is not uniform. More precisely, with reference to the elliptical ring corresponding to a section of the delimiting wall parallel to the second opening, the inner edge of that elliptical crown is more eccentric of the outer edge of the same. The wall of delimitation is therefore thicker in correspondence of the two mutually opposed portions of the same intercepted by the minor axis of that elliptical section. In a first execution of the handpiece of the invention, the delimiting wall includes two closed cavities respectively formed in the two wall portions to greater thickness and containing a thermal gel. In a second execution of the handpiece of the invention, the handpiece is devoid of cavities in the delimiting wall and includes an almost ring shaped band containing thermal gel bags such band is connected to the delimiting wall so as to surround the handpiece, externally. The invention also relates to an apparatus for cryolipolysis treatment, including the handpiece and a manual vacuum pump connectable to the handpiece.
