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. An apparatus for penetrating a bone and associated bone marrow comprising:

a housing;

a drill shaft rotatably disposed within the housing;

the drill shaft operable to connect the needle assembly to a reduction gear assembly disposed within the housing;

a reduction gear assembly disposed in the housing and coupled to the drill shaft;

a motor disposed within the housing and coupled to the reduction gear assembly;

a battery power supply and associated circuitry disposed within the housing and configured to power the motor;

an intraosseous (IO) needle assembly configured to penetrate the bone and associated bone marrow, the IO needle assembly comprising;

an outer needle having a first end, a second end with a plurality of cutting surfaces, and a lumen extending from the first end to the second end;

a first Luer connector disposed on the first end of the outer needle in fluid communication with the lumen;

an inner trocar having a first end and a second end with a plurality of cutting surfaces;

where the inner trocar is disposed partially within the lumen and secured relative to the outer needle such that each of the plurality of cutting surfaces of the inner trocar are co-planar with one of the plurality of cutting surfaces of the outer needle;

where the outer needle is configured to be coupled to the drive shaft via a second Luer connector to which the first Luer connector is connected.

2. The apparatus of claim 1, where the trocar is engaged with the second Luer connector.

3. The apparatus of claim 1, where the second Luer connector is releasably coupled to the drive shaft.

4. The apparatus of claim 3, where the trocar is engaged with the second Luer connector.

5. The apparatus of claim 1, where the first Luer connector is a male Luer connector.

6. The apparatus of claim 5, where the trocar is engaged with the second Luer connector.

7. The apparatus of claim 1, where the trocar is configured to be removed from the outer needle after the IO needle set has penetrated the bone.

8. An apparatus for penetrating a bone and associated bone marrow comprising:

a housing;

a drill shaft rotatably disposed within the housing;

the drill shaft operable to connect the needle assembly to a reduction gear assembly disposed within the housing;

a reduction gear assembly disposed in the housing and coupled to the drill shaft;

a motor disposed within the housing and coupled to the reduction gear assembly;

a battery power supply and associated circuitry disposed within the housing and configured to power the motor;

an intraosseous (IO) needle assembly configured to penetrate the bone and associated bone marrow, the IO needle assembly comprising;

an outer needle having a first end, a second end with a plurality of cutting surfaces, and a lumen extending from the first end to the second end;

a first Luer connector disposed on the first end of the outer needle in fluid communication with the lumen;

an inner trocar having a first end and a second end with a tip;

where the inner trocar is disposed partially within the lumen and secured relative to the outer needle such that the tip of the inner trocar extends beyond the cutting surfaces of the outer needle;

where the outer needle is configured to be coupled to the drive shaft via a second Luer connector to which the first Luer connector is connected.

9. The apparatus of claim 8, where the trocar is engaged with the second Luer connector.

10. The apparatus of claim 8, where the second Luer connector is releasably coupled to the drive shaft.

11. The apparatus of claim 10, where the trocar is engaged with the second Luer connector.

12. The apparatus of claim 8, where the first Luer connector is a male Luer connector.

13. The apparatus of claim 12, where the trocar is engaged with the second Luer connector.

14. The apparatus of claim 8, where the trocar is configured to be removed from the outer needle after the IO needle set has penetrated the bone.
