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, the machine adapter configured to interface with a surgical machine;

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

a replaceable optic fiber;

a first connector of the replaceable optic fiber having a first connector distal end and a first connector proximal end, a portion of the first connector disposed within the handle adapter;

a second connector of the replaceable optic fiber having a second connector distal end and a second connector proximal end, a portion of the second connector disposed within the machine adapter; and

an optic fiber of the replaceable optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed within the first connector and the second connector wherein the optic fiber distal end extends a distal extension distance from the first connector distal end and the optic fiber proximal end extends a proximal extension distance from the second connector distal end.

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

3. The device of claim 2 wherein the machine adapter is sterilized by a medical autoclave.

4. The device of claim 2 wherein the handle adapter is sterilized by a medical autoclave.

5. The device of claim 1 further comprising:

a temporary fixation channel of the first connector; and

a canted coil spring of the handle adapter, the canted coil spring disposed in a canted coil spring housing of the handle adapter.

6. The device of claim 5 wherein the portion of the first connector disposed within the handle adapter is temporarily fixed within the handle adapter.

7. The device of claim 1 further comprising:

a temporary fixation channel of the second connector; and

a canted coil spring of the machine adapter, the canted coil spring disposed in a canted coil spring housing of the handle adapter.

8. The device of claim 7 wherein the portion of the first connector disposed within the machine adapter is temporarily fixed within the machine adapter.

9. The device of claim 1 wherein the distal extension distance is equal to the proximal extension distance.

10. The device of claim 1 wherein the distal extension distance is in a range of 5.0 to 15.0 centimeters.

11. The device of claim 1 wherein the proximal extension distance is in a range of 3.0 to 10.0 centimeters.

12. The device of claim 1 further comprising:

an inner bore of the first connector;

an optic fiber housing of the first connector; and

a connector guide cone of the first connector, the connector guide cone of the first connector configured to guide the optic fiber distal end into the optic fiber housing of the first connector.

13. The device of claim 1 further comprising:

an inner bore of the second connector;

an optic fiber housing of the second connector; and

a connector guide cone of the second connector, the connector guide cone of the second connector configured to guide the optic fiber proximal end into the optic fiber housing of the second connector.

14. The device of claim 1 further comprising:

an end cap of the machine adapter;

a machine adapter base of the machine adapter; and

a machine interface of the machine adapter, the machine interface configured to interface with the surgical machine.

15. The device of claim 14 wherein the surgical machine is an ophthalmic laser.

16. The device of claim 14 further comprising:

an end cap inner bore of the machine adapter;

a canted coil spring housing of the machine adapter; and

a machine adapter base guide cone of the machine adapter.

17. The device of claim 16 further comprising:

a machine interface guide cone of the machine adapter; and

an optic fiber proximal end guide of the machine adapter.

18. The device of claim 1 further comprising:

a handle adapter proximal chamber of the handle adapter;

a canted coil spring housing of the handle adapter; and

a handle adapter guide cone of the handle adapter.

20. The device of claim 1 further comprising:

a handle adapter chamber of the handle adapter; and

a handle proximal end housing of the handle adapter, the handle proximal end housing configured to house a proximal end of a handle.

19. The device of claim 19 further comprising:

a handle interface of the handle adapter, the handle interface configured to interface with a proximal end of a handle; and

a handle adapter projection of the handle adapter, the handle adapter projection configured to be disposed within a handle adapter housing of the handle.
