Abstract
A method for manufacturing an eyeless needle by which a satisfactory hole can be formed in the end surface of a fine suture needle having a needle diameter less than 150 micrometers is proposed. In a method for manufacturing an eyeless needle by forming a hole for inserting and fixing one end of a suture thread by caulking in the end surface of the eyeless suture needle made of stainless steel, the hole is formed by irradiating the end surface of a needle material thicker by 6 to 20 micrometers than a desired needle diameter of the suture needle less than 150 micrometers with one shot of a laser beam, and subsequently, a portion thicker than the desired needle diameter is removed by electrolytic polishing or chemical polishing.
