The present invention relates to a surgical drill-guide assembly that can be releasably attached to a part of a bone-fixation system, for example, a plate. The surgical drill-guide assembly of the present invention is used for example, to guide a drill, screw, bone fastener, or other instrument or fastener into bone.
As shown in FIG. 5, the second part 16 of the dual-arm support 10 may be attached to the first part 14 by a dowel pin 18, or the dual-arm support 10 may be an integral, monolithic construction. The second part 16 of the dual-arm support 10 also forms an obtuse angle θd2 with the handle member 250. θd2 may range from about 90° to about 180°, and more preferably from about 105° to about 1350. The handle member 250 and the dual-arm support 10 generally form an “S” shape or a zigzag shape, and in a preferred embodiment, the longitudinal axis 24 of the first part 14 and the longitudinal axis 26 of the second part 16 lie in the same plane. The longitudinal axis 280 of the handle member 250 also preferably lies in the same plane as the longitudinal axis 24 of the first part 14 and the longitudinal axis 26 of the second part 16 of the dual-arm support 10. Preferably the longitudinal axis 24 of the first-part 14 of the dual-arm support 10 is generally parallel with the longitudinal axis 280 of the handle member 250.
7. The drill-guide assembly, as recited in claim le, wherein the annular diameter of the third cylindrical section is constant along the center line of the cylindrical section.
9. The drill-guide assembly, as recited in claim 8, wherein the outside surface of the alignment drill barrel has a shoulder at the distal end.
17. The drill-guide assembly, as recited in claim 11, wherein the bushing comprises of at least one vertical slot above the circular portion on the bushing.
31. The drill-guide assembly, as recited claim 30, wherein, the first leg of the ratchet-gear mechanism further extends beyond the pivot point forming a C-shaped vice-grip; wherein the C-shaped vice-grip grasps the alignment drill-barrel between the two ridges on the alignment drill-barrel.
39. A method for drilling holes in bone, comprising, providing using a drill-guide assembly having an alignment drill-barrel configured to receive and guide a drill-bit; a bushing configured to slidably receive the alignment drill-barrel, the bushing having a radially expandable forward-end configured to be insertable within a fastener hole in a bone plate; a handle member for grasping by a user; a dual-arm support having first and second parts, the first part of the dual-arm support fixedly connected to the proximal end of the bushing and the second part of the dual-arm support fixedly connected to the handle member; a release knob moveably connected to the handle member, the release knob having serrations; and a ratchet gear mechanism having a first leg, a second leg and a tail, the first leg of the ratchet-gear mechanism pivotably connected to the dual-arm support and further connected to the alignment drill-barrel, the second leg of the ratchet-gear mechanism having pawls that engage the serrations when the ratchet gear mechanism selectively moves, the tail of the ratchet gear mechanism operable by a user to selectively move the ratchet-gear mechanism, wherein, movement of the ratchet-gear mechanism slides the alignment drill-barrel relative to the bushing to radially expand the forward end to releasably lock the bushing to the plate;
(a) inserting the bushing of a drill-guide assembly into fastener holes of a bone-plate;
(b) expanding the bushing in the fastener hole;
(c) locking the bushing to the plate by locking the alignment drill-barrel and the bushing in fixed relation to each other;
(d) aligning a drill-bit along the drilling axis defined through the center of the bore in the alignment drill-barrel;
(e) drilling a first hole;
(f) stopping the drill-bit at a predetermined distance to provide a hole of predetermined depth; and
(g) removing the drill-bit from the alignment drill-barrel.
40. A method for drilling holes in bone, as recited in claim 39, further comprising the steps of:
(a) unlocking the bushing from the plate by pressing the release knob;
(b) releasing the bushing from the fastener hole so that the user can remove the drill-guide assembly from the plate.
