Abstract
A device and method for use in a human spine to prepare a space between adjacent vertebral bodies and into the vertebral end plates to receive an implantable insert. The device includes a handle, a shaft, and a mounting member at one end of the shaft. An abrading element is mounted on the mounting member and is coupled to a drive mechanism. The drive mechanism is operable to move the abrading element in at least one degree of freedom to create surfaces having predetermined contours in the end plates of the adjacent vertebral bodies.
Claims17
An instrument for preparing a space between adjacent vertebral bodies to receive an insert, said instrument comprising:
- a shaft with a longitudinal axis;
- a drive mechanism;
- a power source;
- and
- an abrading element mountable on said shaft, said abrading element including at least one abrading surface having a width selected to substantially match the overall width of the insert to be received between the adjacent vertebral bodies, said abrading element being adapted to rotate by said drive mechanism about an axis generally perpendicular to the longitudinal axis of said shaft and about a plane generally aligned with the vertebral end plate to create at least one surface having a predetermined contour in the end plate of at least one of the adjacent vertebral bodies.
