ABSTRACT:
Method of producing a cannula used specially for a spinal anesthesia. The cannula is provided with a rigid tube whose distal end comprises a zone or region which gradually tapers in the direction of a puncture or insertion point and a lateral exit orifice or aperture embodied therein. The deformation or bending of an angular zone makes it possible to produce the puncture point and the exit orifice in one stage.
