Cavity creation device and methods of use
First Claim
1. A cavity drill configured for use with a bone drill comprising:
- a body configured for releasable coupling to a portion of a bone drill;
an elongate sheath extending from the body; and
a cutting tool coupled to a distal portion of the elongate sheath and comprising a plurality of elongate blades adapted for deployment between a retracted position and plurality of extended positions, the retracted position comprising a configuration that is axially disposed within the elongate sheath, each of the plurality of extended positions comprising a radial configuration whereby the plurality of blades are forced to slide through an end cap coupled to a distal portion of the elongate sheath, the end cap comprising a plurality of openings disposed around a circumference of the end cap through which the plurality of blades are individually extended, each of the plurality of openings defining an angle for deflecting the plurality of blades during extension through the plurality openings;
the plurality of elongate blades being deflectable in at least one direction along their entire length for continuous adjustment of the plurality of blades between the retracted position and the plurality of extended positions.

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. The cavity drill and the bone drill may include a radiation protection guard and radiolucent portions. Methods of use are also provided.
