Abstract

Fastening sternum requires much force, and fastening sternum with stainless wire has difficulties that when the wire is twisted too much the wire will cut off, and when the wire force is too weak, the fixation of the sternum is not sufficient. Also, using stainless steel wire means metal object are left inside the body, and this would cause halation during Magnetic Resonance Imaging photography. This invention proposes a solution for the above, by providing a sternum suture band, wherein a needle is attached on one end of a resin sash form band to pierce through the sternum, one side of the sash having a multiple number of serial projections to prevent untwining of the band, the needle is passed through the box, and then the sternum is gradually fastened and fixed. Fastening of the sternum is facilitated by using a band fastening device for the sternum suture band, wherein the band is inserted from the insertion guide, and when a slide grip is pulled, a hold gear holds one end of the band, and pulls the sternum by pulling the band to the foreside, and when the tension exceeds the pulling intensity of the band the band is automatically cut off.

Claims

1. A sternum suture material utilized during a cardiac surgery, wherein a needle to pierce through the sternum is attached at one end of a resin-made band, the center part of the band is in a sash form, one side of the sash has a multiple number of serial projections to prevent untwining, the other end of the band is made in a box form, the needle that pierces through the sternum passes through inside the box, and the lower side of the upper portion of the inside of the box has receptors to receive the untwining-prevention projections, thus this sternum suture band is made to gradually fasten and then fix the sternum.

2. A sternum suture band according to claim 1, wherein the tip end of the needle attached to one end of the band is in a dull form, not to directly pierce through the sternum but to enable suture along the costae without damaging the internal thoracic artery and other blood vessels.

3. A sternum suture band according to claims 1 and 2, wherein the main part of the band is made of material that are absorbed in the body through mechanisms of hydrolysis or decomposition by enzymes.

4. A fastening device for fastening the sternum suture band according to claims 1, 2 and 3, wherein a sternum suture band is inserted from the insertion guide at one end of the band, the front box of the insertion is adhered closely with the box part, and when the slide grip is pulled, the hold gear holds one end of the sternum suture band, to pull in the sternum to the foreside, and when the tension exceeds the pulling intensity of the sternum suture band, the band is automatically cut off.
