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

a handle adaptor having a handle adapter proximal end and a handle adapter distal end, the handle adapter distal end attached to the handle proximal end;

a curved housing tube disposed within the handle distal end;

a replaceable optic fiber having a pair of connectors;

a temporary fixation channel of each connector of the pair of connectors;

an interface of each connector of the pair of connectors;

a connector inner bore of each connector of the pair of connectors;

a connector guide cone of each connector of the pair of connectors;

an optic fiber housing of each connector of the pair of connectors;

an optic fiber of the replaceable optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the connector inner bore, the connector guide cone, and the optic fiber housing of a first connector of the pair of connectors wherein the first connector has a first connector distal end and a first connector proximal end and wherein the optic fiber distal end extends from the first connector distal end and wherein the optic fiber is disposed in the connector inner bore, the connector guide cone, and the optic fiber housing of a second connector of the pair of connectors wherein the second connector has a second connector distal end and a second connector proximal end wherein the optic fiber proximal end extends from the second connector distal end and wherein the first connector and the second connector are identical;

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 the 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, the end cap being connected to the machine adapter base;

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 an ophthalmic laser;

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:
