Abstract
A manufacturing method for a suture thread with suture needle that has little dispersion in pull-out load and is user-friendly. A blind hole (14) is opened along the length of an eyeless suture needle (10) from a base end surface (13) of the eyeless suture needle (10), a suture thread (18) is inserted in the blind hole (14), and then caulked and formed. A caulking force according to size of diameter of the blind hole (14) is added, cross-sectional form of a caulking part is nearly circular, and the axial length of the caulking part is less than the diameter of the eyeless suture needle (10). According to such a structure, the suture thread (18) may be pulled out from the eyeless suture needle due to a pull-out load within a predetermined force range, and dispersion in pull-out force may be reduced.
