1. A driver assembly comprising:
- a driver comprising;
a motor configured rotate a drive shaft;
a controller coupled to the motor and configured to control the motor; and
a trigger coupled to the controller and configured to activate the motor;
a first electrode coupled to the controller;
a drill bit configured to be coupled to the drive shaft and the controller, the drill bit comprising;
an outer surface having a first end and a second end;
a core extending from the first end of the outer surface and beyond the second end of the outer surface, such that a first end of the core is disposed within the first end of the outer surface and a second end of the core extends beyond the second end of the outer surface; and
an insulator disposed between the core and the outer surface configured to prevent electrical communication between the core and the outer surface;
where the first end of the outer surface, the insulator, and the core cooperate to form at least one tip of the drill bit;
where the second end of the outer surface is configured to be coupled to the drive shaft; and
where the controller is configured to determine at least one of a voltage difference between the core and the first electrode and an impedance between the core and the first electrode when the driver assembly is used in a medical procedure.
