Abstract

A laser probe with a replaceable optic fiber may include a reusable handle, a reusable housing tube, a reusable handle adapter, a reusable machine adapter, and a replaceable optic fiber. The handle adapter may interface with a proximal end of the handle. The machine adapter may interface with a surgical machine. The replaceable optic fiber may include an optic fiber having a first optic fiber end and a second optic fiber end, a first connector, and a second connector. The optic fiber may be disposed within the first connector and the second connector. The first connector may be temporarily fixed within the handle adapter and the second connector may be temporarily fixed within the machine adapter.

Claims

1. A device comprising:

a machine adapter having a machine adapter distal end and a machine adapter proximal end;

a machine adapter base of the machine adapter having a machine adapter base distal end and a machine adapter base proximal end;

a machine adapter base proximal chamber of the machine adapter base;

a machine adapter base inner bore of the machine adapter base;

a machine adapter base guide cone of the machine adapter base, the machine adapter base guide cone configured to guide an optic fiber proximal end of a replaceable optic fiber into the machine adapter base inner bore;

an end cap having an end cap distal end and an end cap proximal end;

an end cap inner bore of the end cap;

a machine interface partially disposed within a machine interface housing of the machine adapter, the machine interface configured to interface with a surgical machine;

a machine interface inner bore of the machine interface;

an optic fiber proximal end guide of the machine interface;

a machine interface proximal taper of the machine interface, the machine interface proximal taper configured to guide the optic fiber proximal end of the replaceable optic fiber into the machine interface inner bore; and

a machine interface guide cone of the machine interface, the machine interface guide cone configured to guide the optic fiber proximal end of the replaceable optic fiber into the optic fiber proximal end guide.

2. The device of claim 1 further comprising:

a canted coil spring housing of the machine adapter.

3. The device of claim 2 further comprising:

a canted coil spring disposed within the canted coil spring housing.

4. The device of claim 3 wherein the canted coil spring has a wire diameter in a range of 0.004 to 0.005 inches.

5. The device of claim 3 wherein the canted coil spring has a minor coil diameter in a range of 0.02 to 0.03 inches.

6. The device of claim 3 wherein the canted coil spring has a major coil diameter in a range of 0.026 to 0.031 inches.

7. The device of claim 3 wherein the canted coil spring is fixed within the canted coil spring housing.

8. The device of claim 7 wherein the canted coil spring is fixed within the canted coil spring housing by a spring force.

9. The device of claim 1 wherein the optic fiber proximal end of the replaceable optic fiber is adjacent to the machine adapter distal end.

10. The device of claim 1 wherein the machine adapter is manufactured from Nylon.

11. The device of claim 1 wherein the machine adapter is manufactured from stainless steel.

12. The device of claim 1 wherein the machine adapter is manufactured from titanium.

13. The device of claim 1 further comprising:

a connector of the replaceable optic fiber having a connector distal end and a connector proximal end, the connector at least partially disposed within the machine adapter.

14. The device of claim 13 wherein the optic fiber proximal end extends a proximal extension distance from the connector distal end.

15. The device of claim 14 wherein the proximal extension distance is a distance in a range of 3.0 to 10.0 centimeters.

16. The device of claim 15 wherein the proximal extension distance is 5.7 centimeters.

17. The device of claim 13 wherein the connector is temporarily fixed within the machine adapter.

18. The device of claim 17 wherein the connector is temporarily fixed within the machine adapter by a canted coil spring.

19. The device of claim 1 wherein the replaceable optic fiber is sterilized by ethylene oxide sterilization.

20. The device of claim 1 wherein the replaceable optic fiber is a single use, disposable medical device.
