Abstract

An apparatus and method for penetrating the bone marrow is provided. The apparatus includes a housing, a penetrator assembly, operable to penetrate the bone marrow, a connector operable to releasably attach the penetrator assembly to a drill shaft, the drill shaft operable to connect the penetrator assembly to a gear assembly, a gear assembly operable to engage and rotate the drill shaft, a motor operable to engage the reduction gear assembly and drive the penetrator into the bone marrow by rotation of the drill shaft, and a power supply and associated circuitry operable to power the motor. The apparatus and method may be adapted to insert a probe through the skull and into the brain.

Claims

1. Apparatus for inserting an intraosseous needle assembly into a bone and associated bone marrow comprising:

a housing having a power supply in the form of a spring disposed therein;

the spring operable to rotate the intraosseous needle assembly;

the needle assembly extending from the housing;

one end of the needle assembly operable to penetrate bone;

a Luer lock connector disposed on another end of the needle assembly;

the Luer lock connector operable to be releasably engaged with a chuck disposed with the housing;

the chuck attached to a gear disposed within the housing;

the spring attached to the gear whereby rotational force applied by the spring to the gear and chuck results in the inserting the one end of the needle assembly into the bone and associated bone marrow; and

means for winding up the spring.

2. The apparatus of claim 1 wherein the spring is operable to be rewound by a knob on the back of the housing.

3. The apparatus of claim 1 further comprising a one-way ratchet operable to rewind the spring.

4. The apparatus of claim 1 further comprising the spring rewound by means of a pull string operable to attach to a spool.

5. The apparatus of claim 1 further comprising the spring rewound by means of a gearbox enclosed in a handle grip.

6. The apparatus of claim 1 further comprising the speed of the spring'"'"'s rotation controlled with rotational weights contained within the housing.

7. Apparatus operable to penetrate bone to monitor intracranial pressure comprising:

a housing having a power supply and a motor disposed therein;

an intracranial probe including a needle assembly;

one end of the needle assembly operable to penetrate bone to monitor the intracranial pressure;

a Luer lock connector disposed on another end of the needle assembly;

the Luer lock connector operable to be releasably engaged with a chuck disposed within the housing;

the chuck attached to a gear disposed within the housing; and

the motor attached to the gear whereby rotational force applied by the motor to the gear and chuck results in the one end of the needle assembly of the intracranial probe penetrating the bone.

8. The apparatus of claim 7 wherein the intracranial probe further comprises a screw.

9. The apparatus of claim 7 further comprising the intracranial probe automatically sealed upon insertion.

10. The apparatus of claim 7 further comprising the intracranial probe containing circuitry operable to connect to a pressure monitor.

11. The apparatus of claim 7 wherein the intracranial probe further comprises a hollow portion operable to allow aspiration of fluid from the patient'"'"'s brain.

12. The apparatus of claim 7 further comprising:

a retractable needle shield extending from the housing; and

the needle assembly disposed within the retractable needle shield prior to the needle assembly penetrating the bone.

13. The apparatus of claim 7 the intracranial probe further comprising a pressure sensor disposed on the tip of the intracranial probe to monitor intracranial pressure.

14. The apparatus of claim 7 further comprising the intracranial probe operable to communicate two-way flow of fluids therethrough.

15. The apparatus of claim 7 further comprising the intracranial probe operable to vent intracranial pressure.

16. The apparatus of claim 7 wherein the intracranial probe further comprises a screwed needle operable to control depth of penetration.
