Abstract

A delivery device for delivering substance to bone includes a luer portion configured to be detachably coupled to a bit driver, the luer portion having a luer thread. A bit portion is rigidly coupled the luer portion, and the bit portion is configured to accommodate the bit driver. A fluted portion is rigidly coupled to the bit portion, the fluted portion comprising a flute, the flute configured to create a hole in the bone. A conduit extends through the luer portion and the bit portion, at least partially through the fluted portion. The flute defines an aperture extending from the conduit entirely through the flute, and the aperture is configured to allow a substance to pass therethrough.

First claim

What is claimed is:

1. A device for delivering substance to bone, comprising:
a luer portion configured to be detachably coupled to a bit driver, the luer portion comprising a luer thread;
a bit portion rigidly coupled to the luer portion, the bit portion configured to accommodate the bit driver;
a fluted portion rigidly coupled to the bit portion, the fluted portion comprising a non-threaded body comprising a flute, the flute configured to create a hole in the bone; and
a conduit, the conduit extending entirely through the luer portion and the bit portion, and the conduit extending at least partially through the fluted portion;
wherein the flute extends from the non-threaded body away from the conduit and defines an aperture, the aperture extending from the conduit entirely through the flute, and the aperture is configured to allow the substance to pass therethrough; and
wherein the device further comprises a plurality of grooves extending from the aperture to facilitate flow of the substance from the aperture to the bone.

2. The device of claim 1 , wherein the bit portion further comprises at least one hex bit configured to be detachably coupled to a hex bit driver.

3. The device of claim 1 , wherein the luer portion defines a cutout, the cutout configured to detachably couple to a screwdriver.

4. The device of claim 1 , further comprising a threaded portion rigidly coupled to the bit portion, the threaded portion comprising a thread.

5. The device of claim 4 , wherein the thread is configured to secure the device into the bone.

6. The device of claim 5 , further comprising a tip, the tip configured to prevent the conduit from extending entirely through the fluted portion.

7. The device of claim 6 , wherein the tip is configured to cut the bone.

8. The device of claim 4 , wherein at least one of the luer portion, the bit portion, the threaded portion, and the fluted portion are individual components assembled during a manufacturing process.

9. The device of claim 8 , wherein the aperture is configured to allow the substance to pass through the aperture such that the substance is in contact with the bone and the fluted portion.

10. The device of claim 1 , wherein the plurality of grooves extend axially from the aperture.

11. The device of claim 1 , wherein the luer thread is configured to be detachably coupled to a peripheral substance delivery device.

12. The device of claim 11 , wherein the peripheral substance delivery device is configured to deliver a curable material.

13. The device of claim 1 , wherein the aperture is formed having a non-constant cross-sectional diameter extending from the conduit to an exterior surface of the flute.

14. The device of claim 1 , wherein the plurality of grooves include a first groove and a second groove, wherein the first groove and the second groove extend axially from the aperture in opposing directions to facilitate flow of the substance from the aperture to the bone.

15. A device for delivering substance to bone, comprising:
a luer portion configured to be detachably coupled to a bit driver, the luer portion comprising a luer thread;
a bit portion rigidly coupled to the luer portion, the bit portion configured to accommodate the bit driver;
a fluted portion rigidly coupled to the bit portion, the fluted portion comprising a non-threaded body comprising a flute, the flute configured to create a hole in the bone;
a threaded portion rigidly coupled to and proximate the bit portion, wherein the fluted portion extends into the threaded portion such that threads of the threaded portion include at least one broken section; and
a conduit, the conduit extending entirely through the luer portion and the bit portion, and the conduit extending at least partially through the fluted portion;
wherein the flute extends from the non-threaded body away from the conduit and defines an aperture, the aperture extending from the conduit entirely through the flute, and the aperture is configured to allow the substance to pass therethrough, and
wherein the flute includes a plurality of grooves extending from the aperture to facilitate flow of the substance from the aperture to the bone.

16. A device for delivering substance to bone, comprising:
a luer portion configured to be detachably coupled to a bit driver, the luer portion comprising a luer thread;
a bit portion rigidly coupled to the luer portion, the bit portion configured to accommodate the bit driver;
a fluted portion rigidly coupled to the bit portion, the fluted portion comprising a non-threaded body comprising a flute, the flute configured to create a hole in the bone, wherein the flute extends circumferentially around a portion of a circumference of the fluted portion; and
a conduit, the conduit extending entirely through the luer portion and the bit portion, and the conduit extending at least partially through the fluted portion;
wherein the flute extends from the non-threaded body away from the conduit and defines an aperture, the aperture extending from the conduit entirely through the flute, and the aperture is configured to allow the substance to pass therethrough, and
wherein the flute includes a plurality of grooves extending from the aperture to facilitate flow of the substance from the aperture to the bone.
