  • Patent number: 5330441
    Abstract: A surgical suturing needle is formed to have a needle shaft with a rectangular cross-section and a needle head with a triangular needle point. A transitional portion between the needle shaft and the needle head is formed to have a maximum width greater than the width of the needle shaft. A plurality of cutting edges extend from the needle point to at least the maximum width section of the transitional portion. After forming and grinding the suturing needle, it is immersed in an acid bath and exposed to an electrical field. Finally, the surgical needle is heat-treated to increase its strength and resistance to bending or breaking.
