Abstract
One side wall of a rigid needle tube is provided at its front end with a curved bending directed towards the opposite, axial side wall and has a lumen opening formed therein. The lumen opening is provided with a rear inner cutting edge and a front punctuating portion which comprises a lancet-shaped tip having a facet grinding. The tip is arranged in a zone defined by two imaginary lines extending respectively from the inner surface and the outer surface of the axial side wall beyond the rear cutting edge of the lumen opening. When using the needle, no material is punched out of the material to be perforated.
