Abstract

A guide for aligning a drill bit or pin used in surgical procedures which is X-ray transparent and utilises gears mounted within a housing. A drive source engages with the drill adapter rod which in turn rotates, via the gears, a drill bit or pin which is held by the adapter. The drive source is located and oriented out remotely from an alignment path for the direction of the drill bit or pin. The housing, gears and the means for holding the drill bit or pin are formed of X-say transparent material.
