Biopsy syringe comprising a needle (2) provided with a cannula (4), which has two slots (8) in the vicinity of its distal end (V), and two grasping tongues (9, 10), which are integral with a further outer cannula (12) arranged around said cannula (4); the cannula (4) is rotated relative to the outer cannula (12) so that the tongues (9, 10) slide along the slots (8); during the rotation of the cannula (4), the tongues (9, 10) are bent towards the inside of the cannula (4) so as to grip a sample of a biological tissue of interest and, therefore, perform a clean resection of said sample. |
