<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an eyeless suture needle for making a hole stably in a short time. <P>SOLUTION: In the method for manufacturing an eyeless suture needle for making the hole 12 longitudinally from the proximal end surface 11a of the eyeless suture needle 10 along the eyeless suture needle and for caulking by inserting a suture 20 into the hole, the hole 12 is bored by cold forging on the proximal end surface 11a by a rod-like member 22 while the proximal end portion 11 of the eyeless suture needle is supported in the process of making the hole 12 from the proximal end surface 11a of the eyeless suture needle 10 along the length direction of the eyeless suture needle. <P>COPYRIGHT: (C)2010,JPO&INPIT |
