When a biotissue is sutured using a curved medical suture needle, the penetration resistance becomes uniform. In a bending method, 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 wound around the roller via a separating member, and then the roller is rotated and the belt is winded, thereby pressing and curving the straight needle-shaped material onto the processing surface. In a suture needle, a portion of a tip side including the needle point is formed as a non-restricted portion which is not restricted by the processing surface of the roller, and a portion except for the non-restricted portion is formed as a curved portion which is bent along the processing surface of the roller.
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 so that the straight needle-shaped material is pressed onto the processing surface and is then curved, the needle comprising:
