Abstract

A device comprising a housing including a palm portion, a sheath portion extending from one end of the palm portion, and a slot comprising an adjustable platform capable of receiving a syringe and a needle connected to the syringe with the needle resting in the sheath portion. A trigger mechanism is connected to the adjustable platform. Adjustment of the trigger mechanism in a first direction moves the platform along the slot toward the sheath portion and adjustment of the bidirectional trigger mechanism in a second direction moves the platform away from the sheath. A light element is connected to the housing and is capable of directing light along the sheath portion away from the palm portion. A power source is electrically coupled to the light element to provide electrical power to the light element. Also disclosed is a system comprising the device, as well as methods of using the device.

First claim

What is claimed is:

1. A device comprising:
a housing comprising:
a palm portion and a sheath portion extending from one end of the palm portion;
a slot comprising an adjustable platform capable of receiving a syringe and a needle connected to the syringe, wherein the adjustable platform is configured such that when the syringe is positioned on the adjustable platform, the needle rests in the sheath portion; and
a bidirectional trigger mechanism positioned proximate the palm portion toward the sheath portion and connected to the adjustable platform, wherein adjustment of the bidirectional trigger mechanism in a first direction moves the adjustable platform and the syringe along the slot toward the sheath portion and, when moved sufficiently in the first direction, extends the needle beyond the sheath portion to expose the needle beyond the sheath portion and adjustment of the bidirectional trigger mechanism in a second direction moves the adjustable platform and the syringe along the slot away from the sheath portion and, when moved sufficiently in the second direction, retracts the needle from being exposed beyond the sheath portion;

a light element connected to the housing and capable of directing light along the sheath portion away from the palm portion; and
a power source electrically coupled to the light element to provide electrical power to the light element.

2. The device according to claim 1 , wherein the sheath portion comprises a first channel for receiving a needle and a second channel for receiving the light element.

3. The device according to claim 2 , wherein the first channel is a semicircular open channel and the second channel is a tube.

4. The device according to claim 1 further comprising:
a locking mechanism connected to the bidirectional trigger to lock the adjustable platform in place.

5. The device according to claim 1 , wherein the adjustable platform further comprises:
a ratchet connected to a linear motion mechanism.

6. The device according to claim 1 further comprising:
a fiber optic bundle capable of focusing light from the light element along the sheath portion.

7. The device according to claim 1 , wherein the power source is a battery.

8. A system comprising:
the device according to claim 1 and
a syringe comprising a reservoir, a plunger, and a needle, wherein when the reservoir is positioned on the adjustable platform the needle rests in the sheath portion.

9. A surgical method comprising:
providing a system comprising:
a syringe comprising a reservoir, a plunger, and a needle and
a device comprising:
a housing comprising:
a palm portion and a sheath portion extending from one end of the palm portion;
a slot comprising an adjustable platform capable of receiving the syringe and the needle, wherein when the reservoir is positioned on the adjustable platform the needle rests in the sheath portion, and wherein the reservoir comprises a photo curable material; and
a bidirectional trigger mechanism positioned proximate the palm portion toward the sheath portion and connected to the adjustable platform, wherein adjustment of the bidirectional trigger mechanism in a first direction moves the adjustable platform and the syringe along the slot toward the sheath portion and, when moved sufficiently in the first direction, extends the needle of the syringe beyond the sheath portion to expose the needle beyond the sheath portion and adjustment of the bidirectional trigger mechanism in a second direction moves the adjustable platform and the syringe positioned along the slot away from the sheath portion and, when moved sufficiently in the second direction, retracts the needle from being exposed beyond the sheath portion;

a light element connected to the housing and capable of directing light along the sheath portion away from the palm portion; and
a power source electrically coupled to the light element to provide electrical power to the light element, wherein the reservoir comprises a photo curable material; and

positioning the sheath portion proximal to a surgical site;
adjusting the bidirectional trigger mechanism in a direction to move the adjustable platform along the slot toward the sheath portion, wherein said adjusting extends the needle beyond the sheath portion;
pressing the plunger to extrude the material out of the needle and onto the surgical site; and
activating the light element to cure the material.

10. The method according to claim 9 , wherein the surgical site is a herniated disc.

11. The method according to claim 9 , wherein the material is a photo-curable hydrogel.

12. A device comprising:
a housing comprising:
a palm portion and a sheath portion extending from one end of the palm portion, wherein the sheath portion has a proximal end connected to the palm portion and an adjustable distal end, the adjustable distal end being retractable;
a slot capable of receiving a syringe and a needle connected to the syringe, wherein the slot is configured such that when the syringe is positioned in the slot, the needle rests in the sheath portion;
a bidirectional trigger mechanism connected to the adjustable distal end of the sheath portion, wherein movement of the bidirectional trigger mechanism in a first direction retracts the adjustable distal end to expose the needle beyond the sheath portion when the syringe is positioned in the slot and movement of the bidirectional trigger mechanism in a second direction extends the adjustable distal end so that the needle is not extended beyond the sheath portion when the syringe is positioned in the slot;

a light element connected to the housing and capable of directing light along the sheath portion away from the palm portion;
a power source electrically coupled to the light source to provide electrical power to the light element.

13. The device according to claim 12 , wherein the sheath portion comprises a first channel for receiving a needle and a second channel for receiving the light element.

14. The device according to claim 13 , wherein the first channel is a semicircular open channel and the second channel is a tube.

15. The device according to claim 12 further comprising:
a locking mechanism connected to the bidirectional trigger mechanism to lock the adjustable distal end of the sheath in place.

16. The device according to claim 12 further comprising:
a fiber optic bundle to focus light from the light element along the sheath portion.

17. The device according to claim 12 , wherein the power source is a battery.

18. A system comprising:
the device according to claim 12 and
a syringe comprising a reservoir, a plunger, and a needle, wherein the reservoir is positioned in the slot and the needle rests in the sheath portion.

19. A surgical method comprising:
providing the system of claim 18 , wherein the reservoir comprises a photo-curable material;
positioning the sheath portion proximal to a surgical site;
adjusting the bidirectional trigger mechanism in a direction to retract the adjustable distal end, wherein said adjusting exposes the needle beyond the sheath portion;
pressing the plunger to extrude the material out of the needle and onto the surgical site; and
activating the light element to cross-link the material.

20. The method according to claim 19 , wherein the surgical site is a herniated disc.

21. The method according to claim 19 , wherein the material is a photo-curable hydrogel.
