Abstract:
A drill sleeve includes a lower end that engages a bone being drilled with a drill bit of a drill during an orthopedic procedure, an upper end that is movable with respect to the lower end, and a fluid damper between the upper and lower ends for resisting movement of the upper end with respect to the lower end and which may reduce a distance at which a drill bit can plunge through a back side of the bone by increasing resistance to drill movement at occurrence of plunge through the back of the bone. The drill sleeve may include measurement scale and a lock that prevents relative motion of the upper and lower ends after the bone has been drilled for evaluating a position of a depth indicator with respect to the measurement scale that corresponds to a depth of the bore in the bone.
