Abstract
A cavity drill is provided, which is configured for use with a bone drill. The cavity drill includes a body. The bone drill has a first portion movably connected to a second portion. A third portion is movably connected to the second portion. The body is mounted with the third portion of the bone drill. A sheath extends from the third portion to a distal end. A curette is connected with the distal end of the bone drill. The curette is composed of retractable cutting tines/blades which are turned/powered by the bone drill motor. The curette tines can be used in a partially or fully deployed state and at low or high speed. The curette is designed to create cavities of varying size in a bone.
