| description | Strength of a front end part having a sharp point of a medical suture needle is maintained and resistance when piercing tissue is reduced. There is provided a medical suture needle having a triangular cross section made of austenitic stainless steel having a fibrously extending structure, having two first slanted surfaces (11) ground and sandwiching a ridge (20), and a bottom surface (13) sandwiched between the two first slanted surfaces and ground. The ridge is formed comprising a first cutting blade (1) that is formed by the two first slanted surfaces (11) intersecting, a ridge part (20) that is formed on a body part side of the first cutting blade without the first slanted surfaces (11) intersecting, and a second cutting blade (2) that is formed by two second slanted surfaces (12) ground, intersecting and sandwiching the first cutting blade (1) on a front end side of the first cutting blade (1). Length L2 of the first cutting blade is within a range of 3 to 20 times length L1 of the second cutting blade (2), and a front end (3) of the second cutting blade (2) is positioned deviating from the material center. |
