Embodiment Construction

[0032] The drawings illustrate a preferred embodiment of the invention, and like numerals in different drawings represent like and corresponding parts.

[0033] Various embodiments of the present invention provide illumination probes with heat-resistant terminated plastic optical fibers. The embodiments of the present invention are applicable to plastic optical fibers of all specifications (such as 20, 23, 25, etc.). There is now a trend towards gauge 25 and especially gauge 23 - smaller diameter indications which allow sutureless wounding of the sclera. Heat-resistant lighting probes are part of surgical systems such as ophthalmic lighting and are useful in many medical procedures such as vitreoretinal / posterior segment surgery. A typical ophthalmic illuminator may include a manual component that transmits a relatively incoherent light beam from a light source (eg, xenon light source, halogen light source, etc.) to the surgical field through an optical fiber. The heat resis...

Abstract

In embodiments of the invention, a plastic optical fiber is bonded to a high temperature distal part to form a thermally robust illumination probe. The distal part is short in length, is made of a high temperature material(s), has a proper shape for guiding light in a desired application, and may be coated with a reflective coating to ensure that the light rays trapped within the part do not escape when the side of the part is in contact with high refractive index or absorptive materials. The distal part may be made of high temperature material(s) such as high temperature plastic rods, glass optical fibers, and so on. The distal end may be tapered or sculpted to a desired configuration. The plastic optical fiber and the high temperature distal part may be joined, using an optical adhesive, inside a steel cannula, a plastic hub, an optical connector, etc.
