<P>PROBLEM TO BE SOLVED: To provide a suture needle capable of improving piercing property by reducing piercing resistance on piercing the biological tissue. <P>SOLUTION: The suture needle has a needle tip 3 formed on one end of a trunk 2 of a needle body 1 and a needle base 4 having a thread attaching section 7 formed on the other end of the trunk 2. The needle tip 3 of the needle body 1 is provided with microscopic irregularities 5 formed by blasting. With such a configuration, when the suture needle is pierced into the biological tissue, a microscopic gap is formed between the irregularities 5 and the tissue. The contact area between the surface of the needle and the biological tissue is thus decreased to reduce the piercing resistance and to improve the piercing property. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
