Monofilament wires or threads are woven, becoming a wire with ring forms. The center part of the wire is in a plain weave in a tape form. The material is to be either non-magnetic property material or bio-absorbable material. An automatic weaving machine is utilized to manufacture the wire. The center part of the metal cable is woven with thin metal filaments, and either one end or both ends of the cable are hardened with silver wax to facilitate the attachment of a suture needle to the ends of the cable. Also, the hardened end of the cable is directly processed into a suture needle form. A U-shaped sternum fixing hook and an adjusting screw press and fix the sternum, a piercing tool pierces a hole into the sternum, then sternum suture material is passed through the sternum, then the sternum suture is conducted. The thickness of the base of the sternum fixing hook is set to prevent the needlepoint of the piercing tool from reaching the lung, or a protection plate can be provided. The center part of the wire is made in a U-shape in advance. A straight needle with a wire is fixed, and pierced from below the sternum. Sternum fixing hooks are continuously fixed with ball joints, making a fixing arm and a movable arm, having the function to open and close the incision sides of the sternum. With the above proposal it is possible to provide a smooth and easy-to-handle sternum suture material which does not establish metal fatigue, prevents halation when using the MRI, health insurance can be applied, easier to fasten, less bleeding, prevents vertical gaps of the sternum when closing the sternum. Piercing the sternum can be done easily, precisely, and safely, and then conduct the sternum suture. The operator does not need to remove needles or guide-wires. This is less invasive to the sternum. This invention does not harm the lung. An affordable and convenient manufacturing method can be provided. |
