FIELD: medical equipment, applicable for puncture biopsy of surface tissues with an easy access. SUBSTANCE: the device has an aspirating needle with bioptation elements and a cryoapplicator in the form of a vessel of titanium nickelide with a through porosity within 8 to 70%, located along the aspirating needle enveloping it. The cryoapplicator is contracted to the needle working end and polished on the contracted end. EFFECT: reduced time of psychoemotional stress and reduced possibility of spreading of tumoral cells, reduced activity of them. 1 cl, 4 dwg
