Abstract

See full text

A method of forming a bore for attachment of an end of a suture, in a proximal end portion of an eyeless operating needle. An original needle is prepared which has its outer diameter greater than that of the operating needle. Beam is applied to an end face of a proximal end portion of the original needle to form the bore therein extending along an axis of the proximal end portion of the original needle, with an outer peripheral portion of the original needle serving as a heat conductive material. Subsequently, an outer diameter of the original needle is reduced to remove the outer peripheral portion from the original needle, to form the operating needle. Alternatively, a separate heat conductive material is disposed around at least one eyeless operating needle and is removed after the bore is formed in the proximal end portion of the operating needle.
