Abstract

An apparatus, method, and system for connecting optical fibers, commonly used in medical instruments, for use in endoscopy, non-evasive treatments of disease, as well as other medical factions incorporating optical fibers, wherein the novel connector allows for rotation of at least one optical fiber within the connector.

First claim

The invention claimed is:

1. An apparatus for connecting optical fibers comprising:
a male plug housing at least two fibers,
a female plug housing at least two fibers and configured to mate with the male plug, and
a mechanism for connecting the fibers of the male plug with the fibers of the female plug,
wherein at least one of the at least two fibers of the male plug, and at least one of the at least two fibers of the female plug, are both configured to rotate or axially translate within the apparatus, and
wherein at least one of the at least two fibers of the male plug and at least one of the at least two fibers of the female plug are stationary, when the at least one of the at least two fibers of the male plug and at least one of the at least two fibers of the female plug both rotate or axially translate within the apparatus.

2. The apparatus according to claim 1 , wherein the mechanism for connecting the fibers is selected from the group comprising of a ferrule connector, alignment sleeve, plug connector, derivatives thereof, and combination therefrom.

3. The apparatus according to claim 1 , further comprising a motor in communication with the at least one fiber, wherein the motor is configured to rotate or axially translate the at least one fiber.

4. The apparatus according to claim 1 , further comprising an alignment mechanism for aligning the female plug with the male plug.

5. The apparatus according to claim 1 , further comprising a scope to be used in conjunction with the apparatus, wherein the apparatus is configured for engaging and disengaging the scope.

6. The apparatus according to claim 1 , further comprising a console to be used in conjunction with the apparatus, wherein the apparatus is for engaging and disengaging the console.

7. The apparatus according to claim 6 , wherein the console comprises:
a spectrometer;
a motor;
and a light source in communication with an at least one of the at least two fibers.

8. The apparatus according to claim 1 , wherein the at least one fiber configured to rotate or axially translate within the apparatus is selected from the group comprising an illumination fiber, a detection fiber, derivatives thereof, and combination therefrom.

9. The apparatus according to claim 1 , wherein the at least one fiber configured to rotate or axially translate within the apparatus is in communication with an illumination fiber.

10. The apparatus according to claim 1 , further comprising a locking mechanism for connecting the male plug housing and female plug housing, wherein the locking mechanism is selected from the group comprising a cam lock, a bayonet, twist lock, push lock, derivatives thereof, and combination therefrom.

11. The apparatus according to claim 1 , further comprising a detection mechanism for detecting if the connection between the male plug housing and female plug housing is proper.

12. The apparatus according to claim 1 , further comprising a spring configured to maintain connection of the at least two fibers while in use.

13. The apparatus according to claim 1 , wherein the male plug housing is disposable and configured for single use.

14. The apparatus according to claim 1 , wherein the female plug housing is disposable and configured for single use.

15. The apparatus according to claim 1 , further comprising a safety mechanism for protecting the at least two fiber of the connector when not connected.

16. The apparatus according to claim 15 , wherein the safety mechanism is selected from the group comprising a safety cap, a shutter, derivatives thereof, and combination therefrom.

17. An apparatus for connecting optical fibers comprising:
a male plug housing at least two fibers,
a female plug housing at least two fibers and configured to mate with the male plug, and
a mechanism for connecting the fibers of the male plug with the fibers of the female plug,
wherein once the female plug is mated with the male plug, at least one of the at least two fibers is configured to rotate or axially translate both within the female plug and male plug, while at least one of the at least two fibers is stationary both within the female plug and male plug.

18. The apparatus according to claim 17 , wherein the mechanism for connecting the fibers is selected from the group comprising of a ferrule connector, alignment sleeve, plug connector, derivatives thereof, and combination therefrom.

19. The apparatus according to claim 17 , further comprising a motor in communication with the at least one fiber, wherein the motor is configured to rotate or axially translate the at least one fiber.

20. The apparatus according to claim 17 , further comprising an alignment mechanism for aligning the female plug with the male plug.
