主权项

1. A driver comprising:
a drive shaft configured to be coupled to an intraosseous device; a motor coupled to a power source and further coupled to the drive shaft by a multi-gear drive system, where the motor is coupled in fixed relation to at least one gear of the multi-gear drive system; and a trigger coupled to the motor and configured to activate the motor to move the drive shaft; where the multi-gear drive system is configured to cause oscillating rotation of the drive shaft, where the multi-gear drive system comprises a first gear comprising:
a first bore, the motor configured to extend through the first bore to rotate the first gear;a first surface extending radially outward from the first bore;a second surface extending radially inward from an outer edge of the first gear; anda third surface between the first and second surfaces and recessed with respect to the first and second surfaces forming an inner wall and an outer wall, where a portion of the inner wall comprises a first plurality of teeth and a portion of the outer wall comprises a second plurality of teeth.
