摘要:
A surgical needle for sutural treatment having a triangle or polygon body in cross section, including a blunt needle point with a plate or round end and at least two cutting edges to prevent a health care provider from mistakenly hurting themselves even if the needle comes into contact with the tissue of the health care provide, and to provide a property that enables the needle to pass smoothly through tissues. A first face of the body may be ground by a grinding apparatus specially made for the surgical needle to form a tapered slope and the cutting edges. By pressing a material piece of the needle in a V-shaped groove it forms a second and third face and readily produces a high quality surgical needle.
