Abstract

A fiber detector apparatus includes a hub having one or more electrical contacts. The hub is configured to be placed against a connector, which is disposed on an electromagnetic energy source, such that electrical continuity is established between the electrical contacts of the hub and electrical contacts on a connector plate of the electromagnetic energy source. The number and positions of the electrical contacts correlate with the presence and characteristics of one or more fibers extending through the hub toward the electromagnetic energy source. A data storage microcircuit may also be provided within the hub to store identification information about the fibers being used. Knowing the physical characteristics of the fibers being used in a particular procedure can permit a user of the apparatus to improve the effectiveness of a procedure using the electromagnetic energy.

Claims

1. A fiber detector apparatus, comprising:

a hub having a proximal end and a distal end, and having a longitudinal axis through a lumen extending through the proximal and distal ends, wherein the hub is structured to receive through the lumen a fiber guide tube, which has a proximal end coupled to the hub and a distal end including a material remover; and

a plurality of retractable pins that provide fiber identification information of a fiber within the fiber guide tube, the retractable pins being provided at a leading surface of the proximal end of the hub.

2. The apparatus of claim 1, wherein each of the retractable pins is in electrical communication with the other retractable pins.

3. The apparatus of claim 1, further comprising a microcircuit connected to the retractable pins.

4. The assembly of claim 1, wherein the fiber is an optical fiber.

5. The assembly of claim 4, further comprising a microcircuit in contact with the retractable pins.

6. The assembly of claim 5, wherein the number and position of the retractable pins is indicative of characteristics of the fiber.

7. The assembly of claim 6, wherein the characteristics of the fiber include the fiber'"'"'s length, shape, diameter, and type.

8. A fiber guide assembly, comprising:

a fiber guide tube having a proximal end and a distal end including a material remover; and

a hub having a proximal hub end and a distal hub end, the hub being positioned around the proximal end of the fiber guide tube, wherein the hub includes a plurality of retractable pins at the proximal hub end.

9. The assembly of claim 8, further comprising at least one fiber extending through the fiber guide tube.

10. The assembly of claim 9, wherein the fiber is an optical fiber.

11. The assembly of claim 9, wherein the number and position of the retractable pins is indicative of characteristics of the at least one fiber.

12. The assembly of claim 11, wherein the characteristics include fiber length, shape, diameter, and type.

13. The assembly of claim 8, further comprising a microcircuit in contact with the retractable pins.

14. A method of detecting a fiber attached to a hub, comprising:

(a) providing a hub having at least three retractable pins at a proximal end of the hub;

(b) placing a circuit board into electrical contact with the pins, wherein the number and position of the retractable pins contacting the circuit board determine a coding sequence indicative of the presence of a fiber; and

(c) decoding the coding sequence to determine whether the fiber is attached to the hub, wherein the fiber is detected if the coding sequence reveals a predetermined electrical circuit, and wherein the retractable pins determine characteristics of the fiber including the fiber'"'"'s length, shape, diameter, and type.

15. The method of claim 14, further comprising a microcircuit in contact with the retractable pins.

16. The method of claim 15, wherein the number and position of the retractable pins is indicative of characteristics of the fiber.
