Abstract
A disc space preparation device that has particular application for removing disc material during spinal fusion surgery. The disc preparation device includes a body portion that houses a motor having a shaft attached thereto that is rotated by the motor. The shaft extends through a chamber in a neck portion of the device and into an open head portion of the device at the end of the neck portion opposite to the housing. The head portion rotates relative to the neck portion. The head portion includes a series of blades that are used to cut-away the disc material. The shaft includes an auger that draws the cut material through the neck portion. A suction port is coupled to the chamber in the neck portion to remove the disc material therefrom.
