Patent ID: 8307684

Claim:
A bending method of a medical suturing needle which uses a bending die which is reciprocatively rotated about a rotation center, and a curvature radius of the bending die having a distance from the rotation center to an outer circumferential surface of the bending die is changed corresponding to a rotation angle of the bending die; a belt wound around a portion of the outer circumferential surface of the bending die and having flexibility, and a press roll has a larger diameter than the bending die and the belt is interposed between the outer circumferential surface of the bending die and the press roll which are relatively pressed, and the method comprises the steps of: interposing a rod-shaped medical suturing needle material between the outer circumferential surface of the bending die and the belt in the portion where the outer circumferential surface of the bending die and the press roll are relatively pressed together, reciprocatively rotating the bending die in a winding direction and a rewinding direction, and curving the material in a length direction.
