Bending method and a medical suture needle of the medical suture needle

A When suturing the body tissue by using a curved medical suture needle, to equalize the piercing resistance. A bending method, a straight needle-shaped material A which is thick Mi from the body portion 1 toward the needle point 2 is reduced, wound around the roller 11 through the roller 11 and the separation member 21 having a working surface 11a inserted between the belt 12 curving to press the belt 12 on the processing surface 11a wound to rotate the roller 11. Suture needle B, a portion of the tip side including the needle point 2 is formed as unconstrained portion that is not restricted by the processing surface 11a of the roller 11, and the processed surface of the portion except the non-restraint portion a roller 11 was bent along 11a is formed as a curved portion that has been subjected.
