Abstract
Abstract A large number of needle patterns are integrally associated with each other on an extended U-shaped metal plate. After that, a pointed end of individual needle patterns is formed, and a series of individual needle patterns are divided into a plurality of segmented needle bodies. Then, a suture is inserted into a hollow portion of the needle body. By closing both walls of the needle body, a suture needle can be produced one after another.
