Abstract
Abstract The present invention is in a drill guide (20) that is for use with and for mounting to a "K" wire (13) that has been fitted through an anterior or posterior cruciate ligament tunnel. The drill guide (20) includes identical parallel rails (21) that are mounted to a stationary bracket (22), essentially at right angles, and are journaled to a traveling bracket (25), the traveling bracket further including set screws (28) to releasably lock it to the rails. The stationary and traveling brackets (22) and (25), respectively, are each isosceles triangular in shape, and each mounts a guide cylinder (23) and (26), respectively, at right angles through their apexes such that longitudinal openings through which guide cylinders are aligned to receive the "K" wire fitted therethrough. A trolley (30) is arranged for travel on rails (21) between the stationary and traveling brackets (22) and (25), and can be releasably locked in place. The trolley mounts a replaceable drill sleeve (36) with a barrel (40) that includes a longitudinal hole (41) formed therethrough wherethrough a drill (44) is turned.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
A drill guide comprising, a pair of parallel rails; a stationary bracket mounted to spaced apart aligned ends of said parallel rails, which stationary bracket includes a first longitudinally open guide cylinder that extends therefrom, parallel to said parallel rails; a traveling bracket journaled to said parallel rails other ends to travel therealong, which traveling bracket includes a second longitudinally open guide cylinder that extends therefrom, parallel to said rails; trolley means journaled for travel along said rails; and drill sleeve means for mounting to said trolley, said drill sleeve means having a barrel portion that is open therethrough that will align with a straight wire or pin that is installed through said first and second longitudinally open guide cylinders.
Claim 2
Dependent Claim
120 words
A drill guide comprising, a pair of parallel rails; a stationary bracket mounted to spaced apart aligned ends of said parallel rails, which stationary bracket includes a first longitudinally open guide cylinder that extends therefrom, parallel to said parallel rails; a traveling bracket journaled to said parallel rails other ends to travel therealong, which traveling bracket includes a second longitudinally open guide cylinder that extends therefrom, parallel to said rails; trolley means journaled for travel along said rails; and drill sleeve means for mounting to said trolley, said drill sleeve means having a barrel portion that is open therethrough that will align with a straight wire or pin that is installed through said first and second longitudinally open guide cylinders.
Claim 3
Dependent Claim
50 words
A drill guide as recited in claim 1, wherein the identical parallel rails are solid rods; and the stationary and traveling brackets are identical flat isosceles triangles, with said parallel rails each installed in the brackets proximate to each of the base corners of each said stationary and traveling bracket.
Claim 4
Dependent Claim
31 words
A drill guide as recited in claim 2, wherein the first and second guide cylinders are installed at right angles through the apex of each of the stationary and traveling brackets.
Claim 5
Dependent Claim
24 words
A drill guide as recited in claim 1, further including means for locking the traveling bracket to at least one of the parallel rails.
Claim 6
Dependent Claim
46 words
A drill guide as recited in claim 4, wherein the means for locking is at least one set screw means arranged for manual turning into a passage that is formed into said traveling bracket to intersect an opening wherethrough one of the parallel rails is journaled.
Claim 7
Dependent Claim
72 words
A drill guide as recited in claim 1, wherein the trolley means is a rectangular block that is holed to accommodate the pair of spaced apart parallel rails journaled therethrough and includes a lateral passage that aligns with a straight wire or pin that is installed between said first and second guide cylinders; and the drill sleeve means includes external thread means for turning in a threaded end of said lateral passage.
Claim 8
Dependent Claim
24 words
A drill guide as recited in claim 6, wherein the trolley means includes means for locking to at least one of the parallel rails.
Claim 9
Dependent Claim
45 words
A drill guide as recited in claim 7, wherein the means for locking is at least one set screw means that is arranged for manual turning in a passage that is formed into said traveling bracket to intersect an opening wherethrough a rail is journaled.
Claim 10
Dependent Claim
14 words
A drill as recited in claim 6, wherein the drill sleeve means is removable.
