Claims12
A surgical drill guide assembly comprising:
- a pair of alignment drill tubes each configured to receive and guide a surgical drill bit;
- a pair of bushings configured to slidably receive the pair of alignment drill tubes along a fixed medial convergence, the bushings each having a radially expandable forward end configured to engage fastener holes in a bone plate;
- an actuation bar;
- a drill guide assembly handle coupled to the actuation bar;
- a base coupled to the drill guide assembly handle;
- and
- wherein the alignment drill tubes are pivotably connected to the actuation bar and the bushings are configured and dimensioned to expand within the bone plate fastener holes to releasably lock the bushings to the bone plate, such that movement of the actuation bar toward the base urges the drill tubes into the bushings for expansion of the forward ends thus locking the bushings within the fastener holes of the bone plate.
