Abstract

When closing the sternum in cardiothoracic surgery, elderly people with a fragile sternum can experience bleeding from the suture sites because of loose knots. The knots are loose because of the danger of cutting into the sternum from the tension caused by the suture wire. In extreme cases, the sternum can be fractured. If the closure is attempted intercostally, there are internal thoracic arteries that run longitudinally underneath the sternum and they may be hurt if a sharp needle is used. Intercostal fixation on its own is inadequate, and additional wires that directly insert into the manubrium are required. Of the sternal closure wires currently available, there is discordance in the numbers provided and actually used, resulting in leftovers that need unnecessary sterilization and reuse. To solve the above problems, an intercostal specific blunt needle has been devised, and packaged together with a sharp needle that will directly insert into the sternum. The set may contain one of each needle or a required combination of both, and come in a pre-sterilized pack. The needle is blunt at the cutting edge, and has a hook, or a side hole. The opposite end has a handle attached. The needle is configured so the wire can be hooked on, or threaded through the hook and hole respectively, and the operative procedure involves lifting up the wires.

Claims

1. A suture needle used for the suturing of the sternum in cardiothoracic surgery. The needle, a blunt intercostal suture needle, is used for the passage through the soft tissue located between the ribs, and has the characteristic of being blunt as opposed to being sharp.

2. The blunt intercostal suture needle from section 1 of our claim is combined in a set with a sharp sternal suturing needle, which is directly used to penetrate through the sternum. The set may contain one of each needle or a required combination of both, and come in a pre-sterilized pack to form a suture needle set for sternal closure.

3. The blunt intercostal suture needle from section 1 of our claim has a hook, or a side hole on the cutting end and a handle attached at the opposite end of the needle. After passing this needle through the intercostal soft tissue, a wire is hooked onto the hook, or threaded through the hole at the cutting edge of the needle, so that the procedure for sternal closure is done by lifting up the wire.

4. The blunt intercostal suture needle with a handle from section 3 of our claim is combined in a set with a sharp sternal suturing needle, which is directly used to penetrate through the sternum. The set may contain one of each needle or a required combination of both, and come in a pre-sterilized pack to form a suture needle set for sternal closure.
