Embodiment Construction

[0028] Referring to FIG. 1 , there is shown an exemplary binocular drill guide assembly 100 and plate holder 140 suitable for use with a slotted cervical spine locking bone plate 160 . Although the bone plate, plate holder, and drill guide assembly have been shown and described as being used for the cervical region of the spine, it should be understood that the bone plate features are applicable to other bone plates, and that the drill guide assembly and Plate holders can also be used with other bone plates. Assembly 100 includes handle member 106, offset handle stem 110, release sleeve 120, outer stem 126, and drill guide barrels 130a and 130b. By pressing and holding the button cam 108, the handle member 106 of the drill-guide assembly 100 can be rotated incrementally. The release button cam 108 locks the handle 106 in place relative to the offset handle stem 110 .

[0029] refer to figure 2 , the locking bone plate 160 of the cervical spine has a rough dog bone shape wit...

Abstract

A bone fixation system including a bone plate and surgical drill guide is provided. The drill guide assembly includes one or more alignment drill tubes that are remotely aligned with corresponding fastener holes in the bone plate, and a plate holder to engage a hole in the bone plate. The surgical drill guide is releasably lockable to the plate holder.

Description

technical field [0001] The present invention relates to a bone fixation system comprising a plate and a surgical drill guide releasably attached to each other to provide precise alignment therebetween. More particularly, the present invention relates to a bone plate and plate holder and surgical drill guide assembly having fastener holes oriented at a predetermined angle relative to the plate, the assembly having at least one corresponding fastener hole aligned on the bone plate. Alignment of the fastener holes with the drill guide barrel so that the holes are drilled at the proper angle. Background technique [0002] The use of surgical fixation plates is well accepted in a variety of orthopedic applications. The plates used by the surgeon are used to correct, align and change the pressure on the patient's bone and are usually secured to the bone with a plurality of fasteners, such as screws, which fit through holes in the plate. Proper orientation and alignment of the fa...
