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 an ophthalmic laser to perform a laser

photocoagulation procedure;

a machine adapter inner bore of the machine adapter;

a machine interface of the machine adapter, the machine interface disposed between the

machine adapter distal end and the machine adapter inner bore;

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

an actuation handle having a plurality of actuation arms and a plurality of extension mechanisms;

a replaceable optic fiber;

a pair of connectors of the replaceable optic fiber;

a housing tube having a housing tube distal end and a housing tube proximal end wherein the optic fiber distal end is adjacent to the housing tube distal end;

a first connector of the pair of connectors having a first connector distal end, a first connector proximal end, a first temporary fixation channel, a first interface, a first connector inner bore, a first connector guide cone, and a first optic fiber housing wherein a portion of the first connector is disposed within the handle adapter;

a second connector of the pair of connectors having a second connector distal end, a second connector proximal end, a second temporary fixation channel, a second interface, a second connector inner bore, a second connector guide cone, and a second optic fiber housing wherein a portion of the second connector is disposed within the machine adapter wherein the second connector is identical to the first connector; and

an optic fiber of the replaceable optic fiber having an optic fiber distal end, an optic fiber proximal end, a core, a cladding, and a polyimide buffer wherein the optic fiber is 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 wherein the distal extension distance is equal to the proximal extension distance and wherein the optic fiber is fixed in the first connector and wherein the optic fiber is fixed in the second connector and wherein a portion of the replaceable optic fiber is disposed in the machine adapter wherein the optic fiber proximal end is adjacent to the machine adapter 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 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 1 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 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 1 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 in a range of 5.0 to 15.0 centimeters.

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

11. The device of claim 1 further comprising:

an end cap of the machine adapter; and

a machine adapter base of the machine adapter.

12. The device of claim 11 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.

13. The device of claim 12 further comprising:

a machine interface guide cone of the machine adapter; and

an optic fiber proximal end guide of the machine adapter.

14. 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.

15. The device of claim 1 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.

16. 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.

17. The device of claim 1 further comprising:

a jacket of the replaceable optic fiber wherein the jacket is disposed over a portion of the optic fiber.
