1. A drill bit guide assembly for use with a drill, comprising:
- a fixed bore adapted for receipt of a drill bit during use of the drill bit, the fixed bore extending through at least a portion of a guide member, wherein a central axis of the fixed bore comprises a reference axis;
a plurality of selectable bores each having a different diameter;
a bore selection member comprising at least one of the plurality of selectable bores, the bore selection member being displaceable relative to the fixed bore for aligning at least one of the selectable bores with the reference axis; and
a bore extension member, wherein a distal end of the guide member comprises an attaching mechanism which is engageable to the bore extension member, wherein the fixed bore extends through the bore extension member when the bore extension member is engaged with the guide member, and wherein the attaching mechanism comprises threads, and the bore extension member comprises complementary threads for securing the bore extension member to the guide member.

Abstract
Drill bit guide assemblies related to surgical operations for guiding and stabilizing a drill bit. A guide member houses a fixed bore through which a drill bit may pass. The guide member may also house a bore selection member which houses a plurality of selectable bores. The selectable bores may have a variety of diameters such that a user may choose the selectable bore corresponding to the drill bit diameter being used and align that selectable bore with the fixed bore such that the drill bit may pass through the length of the assembly along the reference axis. The similar diameters of the selectable bore and the drill bit may cause the assembly to stabilize and guide the drill bit.
