Having Illuminating Means Patents (Class 600/245)
  • Patent number: 10092281
    Abstract: A surgical retractor and method for retracting tissue in a patient is anatomically designed for particular muscles and includes a light source the light beam of which is positionable relative to the surgical retractor. The surgical retractor has a pair of retraction blades carried on separate retraction portions held open by ratchet assemblies. Blades are manually retracted and held open by automatically engaging ratchet fingers and are designed to match muscle curvature, minimizing various risks and incision size. The first retraction portion carries the first blade and includes tines each with ratchet grooves, while the second retraction portion carries the second blade on a carriage that is movably carried on the tines. Resilient spring actuated fingers associated with the carriage has ratchet grooves that co-act with the ratchet grooves of the tines to provide the ratchet assemblies between the retraction portions that regulates movement of the carriage and the second blade relative to the first blade.

  • Patent number: 9468366
    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.

  • Patent number: 9005115
    Abstract: An illumination system includes 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.

    Abstract: 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.

  • Patent number: 8348838
    Abstract: A surgical suction instrument having multiple LEDs for selectively providing illumination as light of different wavelengths at the tip thereof. Typically, at least one of the LEDs is chosen to emit polychromatic white light. Individual switches operable by either the surgeon or another member of the surgical team allow any combination of the LEDs to be energized, thereby creating numerous combinations of light wavelength from the novel surgical suction instrument. Control of the intensity of one or more of the LEDs may be provided to further determine the character of the composite light emitted from the multiple LEDs. The LEDs may be powered by self-contained batteries or from an external power source. The device may either be a single use, disposable device or, in alternate embodiments, may be a device intended for multiple uses and capable of withstanding sterilization.
