Abstract
A triangular suture needle having a low thrust resistance and a press mold suitable for manufacturing the same are provided. The triangular suture needle includes: an angular triangular prism-shaped part (100a) on the needlepoint side; a rounded triangular prism-shaped part (100b) connecting to the needle base side of said triangular prism-shaped part; and a thread attaching part (100c) in a needle base end. The entire angular triangular prism-shaped part (100a) is ground, forming a pointed, sharpened part (100d) with a sharp tip. Furthermore, width (w1) of the thickest portion of the sharpened part (100d) is greater than width (w2) of the rounded triangular prism-shaped part connecting to that portion.
