Abstract
The present invention is directed toward an improved spinal needle. A needle hub is disposed about a proximate end of a hollow needle. The needle hub side port indicators provide visual and tactual verification by a user of the orientation of the side port on the needle. The needle hub also includes a window with a magnified view. The invention provides a stylet cap disposed about a proximate end of a stylet that freely slides inside the hollow needle and needle hub. The stylet cap forms a pressure fit with the needle hub, and can be engaged in the pressure fit from any axial orientation.
Claims17
A spinal needle hub system comprising:
- an introducer-hub component, wherein the introducer-hub component is fixably coupled to a proximal end of an introducer having a distal beveled edge, and wherein the introducer-hub component includes at least one indicator that provides visual and tactual verification of the orientation of said distal beveled edge to a user;
- a needle-hub component that is selectively coupled to the introducer-hub component, wherein the needle-hub component is fixably coupled to a proximal end of the needle, and wherein the needle-hub component includes at least one indicator that provides visual and tactual verification to a user;
- and
- a stylet-hub component that is selectively coupled to the needle-hub component, wherein the stylet-hub component is fixably coupled to a proximal end of a stylet.

A spinal needle system comprising:
- an introducer having channel extending from a proximal end of the introducer to a distal beveled end of the introducer;
- a needle having a channel extending from a proximal end of the needle to a distal end of the needle, wherein the needle is configured to selectively extend through the channel of the introducer;
- a stylet having a proximal end and a distal end, wherein the stylet is configured to selectively extend down the channel of the needle;
- and
- a three-part hub system having a transparent portion to indicate fluid flow,
- wherein the three-part hub system comprises:
- (i) an introducer-hub component, wherein the introducer-hub component is fixably coupled to the proximal end of the introducer, and wherein the introducer-hub component includes at least one indicator that provides visual and tactual verification of the orientation of said introducer's distal beveled edge to a user;
- (ii) a needle-hub component that is selectively coupled to the introducer-hub component, wherein the needle-hub component is fixably coupled to the proximal end of the needle, and wherein the needle-hub component includes at least one indicator that provides visual and tactual verification to the user;
- and
- (iii) a stylet-hub component that is selectively coupled to the needle-hub component, wherein the stylet-hub component is fixably coupled to the proximal end of the stylet.

- and
- a three-component hub system that is configured to be interconnected, wherein the hub system has a transparent portion to indicate fluid flow and comprises:
- (i) an introducer-hub component that includes at least one indicator to provide visual and tactual verification of the orientation of said introducer's distal beveled end to a user;
- (ii) a needle-hub component that is fixably coupled to the proximal end of the needle, and wherein the needle-hub component includes at least one indicator that provides visual and tactual verification to a user;
- and
- (iii) a stylet-hub component that is fixably coupled to the proximal end of the stylet.
