Abstract
Driver assemblies, drivers, drill bits, and methods for determining information (such as impedances, voltages, voltage differences, and changes in such information) about biological material during a medical procedure.
Claims20
A driver assembly comprising:
- a driver comprising:
- a controller;
- a motor coupled to a power source and further coupled to the controller such that the controller can affect the motor's operation;
- a drive shaft coupled to the motor such that the motor can move the drive shaft;
- a trigger coupled to the controller and configured to activate the motor;
- and
- a first electrode configured to be coupled to the controller;
- and
- a drill bit configured to be coupled to the drive shaft and the controller, the drill bit comprising:
- an outer surface;
- a core disposed inside 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 outer surface, the insulator, and the core cooperate to form at least one tip of the drill bit;
- 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 when the first electrode is coupled to the controller and at least when the driver assembly is used in a medical procedure.

A driver comprising:
- a controller configured to determine at least one of an impedance and a voltage difference;
- a motor coupled to a power source and further coupled to the controller such that the controller can affect the motor's operation;
- a drive shaft coupled to the motor such that the motor can move the drive shaft;
- a trigger coupled to the controller and configured to activate the motor;
- and
- a first electrode configured to be coupled to the controller;
- where the driver is configured to be coupled to an intraosseous (IO) device and used, with the IO device, to determine at least one of a change in an impedance and a change in a voltage difference across biological material.

A drill bit comprising:
- an outer surface;
- a core disposed inside 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 outer surface, the insulator, and the core cooperate to form at least one tip of the drill bit configured to penetrate bone;
- and
- where the drill bit is configured to be coupled to a driver and used to determine at least one of a change in impedance and a change in voltage difference across biological material during a medical procedure.
