Power surgical drill having an integral depth gauge including a probe that slides over a drill bit

摘要

A drill for pushing a drill bit into a solid object such as bone. The drill includes a rotor having a bore that transmits rotational motion to a drill bit. The drill bit passes through the rotor bore. A probe extends forward from the drill to measure bore depth. The probe is movably attached to the drill so as to extend into the rotor bore. As the drill and drill bit move forward, the probe remains stationary. As the drill advances, the rotor extends across the proximal end of the probe.
