Abstract
An orthopedic drilling system having a collection chamber positioned between a drill guide and a drill bit proximately to the flute of the drill bit to evacuate debris and swarf from a drilling site. The drill bit may be cannulated to define a throughbore in communication with an irrigation inlet. The drill guide can reciprocate into and out of a hub and be connection to a suction source. The flute of the drill bit may have a first outer diameter that is larger than a second outer diameter of an intermediate portion of the drill bit positioned proximately to the flute to define the chamber between the drill bit and the drill guide. Alternatively, the drill guide may have a first inner diameter positioned about the flute of the drill bit and a second, larger inner diameter proximate to the flute to define the collection chamber.
