Abstract

A curved laser probe with single-use optic fiber may include a reusable handle, an optic fiber fixture, and a single-use optic fiber. The single-use optic fiber may include an optic fiber having an optic fiber distal end and an optic fiber proximal end. The optic fiber may be disposed in a first transitory connector having a first transitory connector distal end and a first transitory connector proximal end wherein the optic fiber distal end extends a fixed distance from the transitory connector distal end. The optic fiber may be disposed in a second transitory connector having a second transitory connector distal end and a second transitory connector proximal end wherein the optic fiber proximal end extends a fixed distance from the second transitory connector distal end. The first transitory connector may be inserted in the reusable handle and the second transitory connector may be inserted in the optic fiber fixture.

Claims

1. An instrument comprising:

a first transitory connector having a first transitory connector distal end and a first transitory connector proximal end;

a first inner bore of the first transitory connector;

a first inner bore distal taper of the first transitory connector;

a first optic fiber housing of the first transitory connector;

a second transitory connector having a second transitory connector distal end and a second transitory connector proximal end;

a second inner bore of the second transitory connector;

a second inner bore distal taper of the second transitory connector;

a second optic fiber housing of the second transitory connector;

a jacketing having a jacketing distal end and a jacketing proximal end wherein the jacketing distal end is disposed in the first inner bore and wherein the jacketing proximal end is disposed in the second inner bore;

a curved hypodermic tube having a curved hypodermic tube distal end and a curved hypodermic tube proximal end;

an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the jacketing, the first inner bore, the first inner bore distal taper, the first optic fiber housing, the second inner bore, the second inner bore distal taper, and the second optic fiber housing wherein a first portion of the optic fiber is fixed in the first optic fiber housing and a second portion of the optic fiber is fixed in the second optic fiber housing and wherein the optic fiber distal end extends a first distance from the first transitory connector distal end and the optic fiber proximal end extends a second distance from the second transitory connector proximal end and wherein the first distance is equal to the second distance;

a handle facilitating sleeve having a handle facilitating sleeve distal end and a handle facilitating sleeve proximal end;

a transitory connector housing of the handle facilitating sleeve;

a handle facilitating sleeve inner bore of the handle facilitating sleeve; and

wherein the handle facilitating sleeve is manufactured from a material having a first hardness and the optic fiber is manufactured from a material having a second hardness wherein the second hardness is greater than the first hardness.

2. The instrument of claim 1 further comprising:

a major diameter of the first transitory connector.

3. The instrument of claim 2 further comprising:

a minor diameter of the first transitory connector.

4. The instrument of claim 1 wherein the handle facilitating sleeve and the optic fiber have a coefficient of friction in a range of 0.011 to 0.36.

5. The instrument of claim 1 wherein the handle facilitating sleeve and the optic fiber have a coefficient of friction of less than 0.011.

6. The instrument of claim 1 wherein the handle facilitating sleeve is manufactured from a fluorocarbon material.

7. The instrument of claim 1 wherein the handle facilitating sleeve is manufactured from a material having a density in a range of 0.024 to 0.073 pounds per cubic inch.

8. The instrument of claim 1 wherein the handle facilitating sleeve is manufactured from a self-lubricating thermoplastic material.

9. The instrument of claim 1 wherein the handle facilitating sleeve is manufactured from a TURCITE material.

10. The instrument of claim 1 wherein the handle facilitating sleeve is manufactured from a material having a hardness in a range of 50 Shore D to 75 Shore D.

11. The instrument of claim 1 further comprising:

a handle base having a handle base distal end and a handle base proximal end; and

a handle facilitating sleeve housing of the handle base.

12. The instrument of claim 11 wherein the handle facilitating sleeve is disposed in the handle facilitating sleeve housing.

13. The instrument of claim 12 further comprising:

a handle nosecone having a handle nosecone distal end and a handle nosecone proximal end; and

a hypodermic tube housing of the handle nosecone.

14. The instrument of claim 13 further comprising:

a nosecone housing of the handle base wherein the handle nosecone is disposed in the nosecone housing.

15. The instrument of claim 1 wherein the curved hypodermic tube is manufactured by centerless grinding.

16. The instrument of claim 1 further comprising:

a continuous taper of an outer diameter of the curved hypodermic tube.

17. The instrument of claim 1 further comprising:

a single continuously non-tapered inner diameter of the curved hypodermic tube.

18. The instrument of claim 1 further comprising:

a straight segment with medial termination of the curved hypodermic tube.
