  • Publication number: 20140221763
    Abstract: 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.

  • Publication number: 20140213851
    Abstract: The illumination system comprises an arthroscope, endoscope or other suitable surgical tool and an attachable cannula comprising a transparent or semi-transparent material capable of carrying light from the proximal end of the cannula to the distal end of the cannula, thereby illuminating the surgical field. The surgical field is thus illuminated through components that do not occupy space that may otherwise be used for the optics of the arthroscope. The arthroscopic illumination system further comprises one or more illumination sources disposed at the proximal end of the cannula. The illumination source may be optically coupled with the cannula at the hub or other appropriate location. The cannula comprises a sterilizable polymer which functions as a waveguide. A waveguide is a material medium that confines and guides light. When in use, the light source connected to the hub provides light which may be guided to the distal end of the cannula or any other suitable location.

  • Publication number: 20140153278
    Abstract: A cavity illumination system according to the present disclosure may include one or more illumination elements composed of a transparent or semi-transparent, biocompatible sterilizable polymer and one or more illumination sources. The sterilizable polymer operates as a waveguide. An illumination element may incorporate micro structured optical components such as for example gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The micro structured optical components may also be used to polarize and/or filter the light energy entering or exiting the illumination element.

  • Publication number: 20140133173
    Abstract: A surgical clip for illuminating tissue in a surgical field has first and second elongate arms and a connector joining the arms together. The arms are biased to expand laterally outward into an expanded configuration in which the arms engage the tissue in the surgical field with enough force to seat the clip without retracting the tissue. A waveguide illuminator is coupled to the first arm, and has a light input portion, a light output portion, and a light conducting portion extending between the light input portion and the light output portion. Light passes through the waveguide illuminator by total internal reflection, and the waveguide illuminator directs light to the tissue. Methods of using the illuminated clip are also disclosed.

  • Publication number: 20140121467
    Abstract: A surgical access system includes an access device having a tubular shape and a channel extending through the device that is sized to receive a surgical instrument. The outer surface of the device defines a support section and access section having an aperture extending through the wall of the device. The aperture has a wider distal portion and a narrower proximal portion and the surgical instrument may be inserted through the aperture. The access device simultaneously retracts soft tissue and distracts bone when inserted into the surgical site while allowing a surgeon access to the surgical site.

  • Publication number: 20140058209
    Abstract: An air gap retractor illumination system includes any suitable retractor such as a McCulloch with a channel in the blade to accommodate an air gap illuminator. The illuminator is preferably made from a suitable light conducting plastic material such as acrylic or polycarbonate or silicone. The illuminator has active portions in which light passes and inactive or dead zones in which light does not pass as a result of the configuration and orientation of the input, output and surfaces of the illuminator. The illuminator is formed to have an air gap surrounding any active portion of the illuminator extending from the light input to the light output portion. The dead zones may include elements to allow the illuminator to securely engage the retractor.

  • Publication number: 20140057223
    Abstract: An illuminator film system may include one or more pre-cut sections of optical film applied to a waveguide to allow light to exit the waveguide through the film in a predetermined manner. The one or more pre-cut sections may be removed and reapplied during a procedure to redirect the light. A laminated illuminator film may be provided that uses a laminated optical film structure to direct light from a fiber optic input. Such a laminated illuminator film may be very low profile, low cost and easy to apply to a retractor for providing illumination during a surgical procedure.
