  • Publication number: 20030095781
    Abstract: Illuminated surgical retractors include at least one retractor blade and a light delivery system. In some embodiments of the invention, the light delivery system includes a light emitter in the form of an elongated light emitting blade portion extending along the length of the retractor blade. The light emitter may be coupled to a light source integral with the retractor for illuminating all or a portion of the length of the light emitter or retractor blade. In other embodiments of the invention, the light delivery system may include an array of lights which may be attached directly to the retractor blade or to a support in the shape of an elongated blade that extends along the length of the retractor blade for illuminating all or a portion of the length of the retractor blade.

  • Patent number: 6176824
    Abstract: A fiberoptically illuminated appliance is disclosed. The appliance includes a light source and an elongate fiberoptic cable, which is operably engaged to the light source and which conducts light from the light source therethrough. A translucent appliance is operated in a conventional manner to perform a primary predetermined function, which function is exclusive of lighting. The appliance includes a continuous light conducting pathway that is uninterrupted by air and a light-emitting surface formed on the periphery of the appliance and communicably connected to the light-conducting pathway. The cable and the appliance are communicably interengaged. Light is directed from the cable through the continuous light-conducting pathway to the light-emitting surface, from which surface light is projected to illuminate the primary predetermined function.

  • Patent number: 6080105
    Abstract: An illuminated retractor provides a handle and a blade, the blade having a forward portion composed of a light transmissive material. The forward portion blade of the extends from handle and is formed suitably for retraction of body tissue adjacent to a body cavity to be illuminated. The handle is manually grippable and houses an electrical power source which powers a lamp mounted in blade. The forward portion of the blade is formed of a light transmissive material in optical communication with the lamp and is formed for the emission of an unfocused and diffused light for general illumination of the cavity. A surface region of the blade body may be frosted or ground so as to widely diffuse light emitted from lamp, thereby illuminating a wide area of a body cavity. A plurality of interchangeable blades of diverse shapes includes a perio-ostial elevator tip and a dental cheek retractor. A blank blade is provided which can easily be customized into a variety of shapes.

  • Patent number: 5667480
    Abstract: A method for removing a vessel from a patient's body comprises the steps of identifying the vessel to be removing and providing an incision in the patient's body near the identified vessel. An optical dissector is inserted through the incision and tissue is optically dissected away from the surface of the vessel with the optical dissector. The optical dissector is then withdrawn from the body through the incision. An optical retractor is inserted into the body through the incision and is used to retract the dissected tissue away from the surface of the vessel thereby providing space between the dissected vessel and the retracted tissue. The vessel and its side branches are then dissected, ligated and transected and the vessel is then removed from the body through the incision.

  • Patent number: 5520611
    Abstract: An illuminated retractor provides illumination to a surgical field deep in a cavity in a patient's back. The illuminated retractor has a first blade that is inserted into the cavity and hooks on a vertebrae. A second blade lies on the patient's back. Weights applied to the second blade hold the cavity open. Fiber optic cables are embedded in the illuminated retractor. Output ends of the fiber optic cables terminate at a step in the first blade. Input ends of the fiber optic cables extend from a second blade and are gathered into a fitting. By connecting the fitting to a source of illumination, light is provided by the fiber optic cables output ends to the surgical field. The illuminated retractor first blade is smooth and occupies minimum space so as to not interfere with the surgeon's fingers or instruments.
