ABSTRACT:
A cutting device for the cutting and reduction of matter from a surgical site having a cutting head having an entry tip and a cutting blade positioned on opposed leading edges of a window formed through the interior of the cutting head. The window includes angled walls extending from each cutting blade along the circumference of the window. The cutting head is attached to a shaft for mounting the cutting device to a rotary surgical drill. The cutting head can also have a blade on the outer perimeter of the head. The matter is removed and further reduced as the cutting head is rotated at the surgical site. The geometry of the cutting head and entry tip can be varied for particular surgical procedures. The cutting device can also include a cannula or drill guard.
