Abstract
A spinal implant having a spinal cage and a plurality of staples. The spinal cage is configured to be positioned in an intervertebral space between adjacent vertebrae. The plurality of staples are moveably disposed on the spinal cage and configured to be inserted into the adjacent vertebrae so as to secure the spinal cage in the intervertebral space when the spinal cage is positioned therein. A method of securing the spinal implant within the intervertebral space.
Claims17
A spinal implant comprising:
- a spinal cage configured to be positioned in an intervertebral space between adjacent vertebrae, the spinal cage comprising a top surface and an opposing bottom surface that extend between a proximal end face and an opposing distal end face and that extend between opposing side faces, a first and second through hole each extending into the proximal end face;
- a first pair of staples, each staple of the first pair having a substantially U-shaped configuration and comprising a bone insertion section, a cage insertion section and a bridge extending therebetween, the cage insertion section of each of the first pair of staples being rotatably disposed within the first through hole of the spinal cage so that each bone insertion section thereof can rotate outside of the spinal cage between alignment with one of the side faces of the spinal cage and alignment with one of the top surface or bottom surface of the spinal cage;
- and
- a second pair of staples, each staple of the second pair having a substantially U-shaped configuration and comprising a bone insertion section, a cage insertion section and a bridge extending therebetween, the cage insertion section of each of the second pair of staples being rotatably disposed within the second through hole of the spinal cage so that each bone insertion section thereof can rotate outside of the spinal cage between alignment with one of the side faces of the spinal cage and alignment with one of the top surface or bottom surface of the spinal cage.

A spinal implant comprising:
- a spinal cage configured to be positioned in an intervertebral space between adjacent vertebrae, the spinal cage comprising a top surface and an opposing bottom surface that extend between a proximal end face and an opposing distal end face and that extend between opposing side faces, a first through hole being formed on the proximal end face so as to extend into the spinal cage;
- and
- a first pair of staples, each staple of the first pair having a substantially U-shaped configuration and comprising a bone insertion section, a cage insertion section and a bridge extending therebetween, the cage insertion section of each of the first pair of staples being rotatably disposed within the first through hole of the spinal cage so that each bone insertion section thereof can rotate outside of the spinal cage between alignment with one of the side faces of the spinal cage and alignment with one of the top surface or bottom surface of the spinal cage, each staple of the first pair also having a lip radially outwardly projecting from each cage insertion section, the lips biasing against each other when the bone insertion sections are in the alignment with one of the top surface or bottom surface of the spinal cage so as to preclude further rotation of the bone insertion sections away from the one of the side faces.
