Abstract:
1. A bending method of a medical suture needle in which a straight needle-shaped material which has a thickness decreased from a body portion to a needle point is inserted between a roller having a processing surface and a belt, and then the roller is rotated and the belt is wound on the processing surface so that the straight needle-shaped material is pressed onto the processing surface and is then curved, the method comprising the steps of: providing a belt-shaped separating member between the belt and the processing surface of the roller, separating the belt and the processing surface of the roller without directly contacting each other by the belt-shaped separating member which has a predetermined thickness smaller than the largest thickness of the material provided into a space between the belt and the roller, so that the space is configured in which no bending force acts against the needle point from the processing surface of the roller even when a portion of the belt corresponding to the needle point is completely wound on the processing surface; inserting the needle point of the straight needle-shaped material into the space between the processing surface of the roller and the belt separated by the belt-shaped separating member; and rotating the roller and winding the belt around the roller with the needle point kept in the space, thereby curving the straight needle-shaped material.
