An illumination element has a light input section, a light transmitting section, and a light output section. The light input section is optically coupled to a proximal section of the light transmitting section and inputs light into the illumination element. The light transmitting section transmits the light by total internal reflection or by other transmission means. The light output section is adjacent a distal section of the light transmitting section which has a light extraction area from which the light exits with an energy density. The light extraction area comprises a bore extending at least partially inward into a distal end of the light output section. A plurality of optical structures is disposed on an inner wall of the bore. The optical structures are configured to extract light from the light output section and direct it toward the surgical field.

Thermally controlled illumination devices

An illuminated suction apparatus including a hand-held surgical device combining a high-performance illumination waveguide with suction. This device would be useful in a wide array of various surgical procedures including open and minimally invasive orthopedics.

Illuminated suction apparatus

An illuminated energy device includes a handle, an optical waveguide coupled to the handle, and an energy tip such as an electrode coupled to the optical waveguide. The optical waveguide is preferably adjustably coupled to the optical waveguide, and adjustment of the optical waveguide moves a distal end of the optical waveguide closer to or further away from a target such as tissue in a surgical field.

Methods and apparatus for electrosurgical illumination and sensing

In an example, a surgical retractor includes an elongated shaft extending from a first end to a second end, and a retractor blade extending from the second end of the elongated shaft. The elongated shaft defines an internal chamber. The elongated shaft includes a handle portion at the first end of the elongated shaft, a suction conduit in a first lateral portion of the internal chamber, and a light conduit in a second lateral portion of the internal chamber. The suction conduit extends from a suction port at the first end to a suction aperture at the second end. The light conduit extends from a light-input port at the first end to a light aperture at the second end. The suction conduit and the light conduit are substantially coplanar. The surgical retractor also includes an optical waveguide in the light conduit of the elongated shaft.

A surgical illumination apparatus comprises a fiber optic input, and illuminated surgical instrument, and an optical coupling bracket for coupling the fiber optic input to the illuminated surgical instrument. The coupling bracket comprises an elongate frame having a proximal end, a distal end, and a central channel extending therebetween, wherein the central channel is sized to receive and support optical fibers of the fiber optic input. The proximal end of the bracket is coupled to the fiber optic input, and the distal end of the bracket is coupled to an illumination element of the illuminated surgical instrument. The apparatus may further comprise a shroud disposed around the illumination element that is coupled to the bracket.

An illuminated medical system comprises a medical instrument and a light transmitting waveguide. The waveguide projects lights from a distal portion of the waveguide toward a target area. The waveguide is formed primarily of a cyclic olefin copolymer or a cyclic olefin polymer.

Cyclo olefin polymer and copolymer medical devices

A surgical instrument for illuminating a surgical field has an optical waveguide for transmitting light by total internal reflection. One or more control elements are disposed on the optical waveguide. The control elements extract light from the optical waveguide and control first and second optical properties of the extracted light Another surgical instrument includes a first and second optical waveguide for transmitting light by total internal reflection. A coupling element is attached to both optical waveguides such that the optical waveguides are movable and pivotable relative to one another.

Methods and apparatus for controlling optical properties of light

An illumination element such as an optical waveguide for illuminating a surgical field in a patient has a light input section, a light transmitting section, and a light output section. The light input section is optically coupled to a proximal section of the light transmitting section and inputs light into the illumination element. The light transmitting section transmits the light preferably by total internal reflection or by other transmission means. The light output section is adjacent a distal section of the light transmitting section which has a light extraction area from which the light exits with an energy density. The light extraction area is large enough to maintain the energy density at a level that prevents melting of the illumination element or burning of the patient, and the light extraction area has a profile that does not interfere with access to the surgical field.

Various surgical devices having integrated means of illuminating a surgical field are provided. Retractors, cannulas, suction devices and the like are disclosed having integrated optical waveguides coupleable to external lighting sources. The waveguides feature cladding layers configured to enhance transmission efficiency.
