Abstract
A bone staple and integral insertion device that provides biocompatibility, increased strength, and cost effectiveness is disclosed. Once the bone staple is inserted the desired depth into the bone, the arms of the insertion device are spread apart thereby applying the desired amount of compression to the bone staple. The insertion device can then be broken free from the bone staple, and removed from the patient. In this manner, the amount of compression between the broken ends of the bone can be regulated directly by the surgeon during implantation of the bone staple.
Claims20
A bone staple system comprising:
- a bone staple;
- and
- an insertion device integral to the bone staple and comprising a pair of arm components, wherein the pair of arm components are repositionable to apply compression to the bone staple during implantation.
A bone staple comprising:
- a bridge component;
- a pair of legs, wherein a single leg of the pair of legs is secured to either end of the bridge component;
- and
- an integrally formed insertion device;
- and
- wherein once the bone staple is implanted into a bone, the bridge component is positioned in a cortical portion of the bone and the pair of legs is positioned in a cancellous portion of the bone;
- and
- wherein the integrally formed insertion device applies compression to the bone staple during implantation.
The method of implanting a bone staple using a bone staple system comprising:
- utilizing drill guide components on an insertion device to drill a pair of guide holes into a fractured bone area;
- inserting a bone staple into the pair of guide holes via a pair of legs on the bone staple;
- pulling apart a pair of arm components on the insertion device to add a compressive force to the bone staple;
- and
- separating the bone staple from the insertion device at a break-off point.
