Abstract

A laser probe with replaceable optic fibers may include a handle, an optic fiber fixture, and a replaceable optic fiber. The replaceable 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 handle and the second transitory connector may be inserted in the optic fiber fixture.

Claims

1. An instrument system comprising:

a handle assembly having a handle, a hypodermic tube, a wire, a slider, a piston with a slot, and expansion ring disposed in a portion of the piston;

a first transitory connector having a first transitory connector distal end and a first transitory connector proximal end wherein the first transitory connector is manufactured from a material configured to deform if the first transitory connector is sterilized in a medical autoclave;

a proximal base of the first transitory connector having a proximal base distal end and a proximal base proximal end wherein the proximal base proximal end is the first transitory connector proximal end;

a distal base of the first transitory connector wherein the distal base is disposed between the first transitory connector distal end and the proximal base distal end;

a tapered inner lumen of the first transitory connector;

a first superior arm of the first transitory connector having a first superior arm distal end and a first superior arm proximal end wherein the first superior arm is disposed between the first transitory connector distal end and the first transitory connector proximal end;

a first superior arm barb of the first superior arm wherein the first superior arm barb is disposed between the first superior arm distal end and the first superior arm proximal end;

a first inferior arm of the first transitory connector having a first inferior arm distal end and a first inferior arm proximal end;

a first inferior arm barb of the first inferior arm wherein the first inferior arm barb is disposed between the first inferior arm distal end and the first inferior arm proximal end;

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

a tapered inner lumen of the second transitory connector;

a second superior arm of the second transitory connector having a second superior arm distal end and a second superior arm proximal end;

a second superior arm barb of the second superior arm wherein the second superior arm barb is disposed between the second superior arm distal end and the second superior arm proximal end;

a second inferior arm of the second transitory connector having a second inferior arm distal end and a second inferior arm proximal end;

a second inferior arm barb of the second inferior arm wherein the second inferior arm barb is disposed between the second inferior arm distal end and the second inferior arm proximal end; and

an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the tapered inner lumen of the first transitory connector wherein the optic fiber distal end extends a distance from the first transitory connector distal end.

2. The instrument system of claim 1 wherein the optic fiber is disposed in the tapered inner lumen of the second transitory connector wherein the optic fiber proximal end extends a distance from the second transitory connector distal end.

3. The instrument system of claim 2 wherein the distance that the optic fiber distal end extends from the first transitory connector distal end is equal to the distance that the optic fiber proximal end extends from the second transitory connector distal end.

4. The instrument system of claim 1 further comprising:

a jacketing having a jacketing distal end and a jacketing proximal end, the jacketing disposed over a portion of the optic fiber.

5. The instrument system of claim 1 further comprising:

an illumination optic fiber having an illumination optic fiber distal end and an illumination optic fiber proximal end.

6. The instrument system of claim 5 wherein the illumination optic fiber is disposed in the tapered inner lumen of the second transitory connector wherein the illumination optic fiber proximal end extends a distance from the second transitory connector distal end.

7. The instrument system of claim 6 wherein the distance that the optic fiber distal end extends from the first transitory connector distal end is not equal to the distance that the illumination optic fiber proximal end extends from the second transitory connector distal end.
