Abstract
The goal is to provide a medical suture needle having, as the material, austenite stainless steel with a structure that is elongated in a fiber form while improving the hardness and flexural strength of the cutting portion. A medical suture needle is made of austenite stainless steel having a structure that is elongated in fiber form, and has a cutting portion and a body portion with a triangular cross-sectional shape that is continuous with said cutting portion. The cutting portion has cutting edges, at least one surface of which is formed by a pressed surface, and which are formed by the intersection of said pressed surface with two sharpened surfaces, and a cutting edge that is formed by the intersection of the two sharpened surfaces. The tip where the various cutting edges and converge is positioned in the center of the pressed surface. Moreover, the cutting edges formed by the intersection of the above pressed surface with the two sharpened surfaces are longer than the cutting edge that is formed by the intersection of the two sharpened surfaces.
