  • Patent number: 11583175
    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: 10226555
    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.

    Abstract: The invention is a simple surgical drape system for female urology procedures that provides sealed isolation of top versus bottom sides of the drape and only exposes the female urethral meatus area for the procedure. It is achieved by a combination of a drape with a fenestration, a labia spreader where the drape fenestration is attached to provide a seal, and local illumination of the meatus area integrated in the drape system for safer and easier instrument insertion. The labia spreader also frees up one of the operator's hands and provides protection for false catherization. The labia spreader can have a vaginal inserted portion for precise position fixation of the drape fenestration to the female. The drape system also provides improved liquid management made possible by the unique combination of drape and labia spreader acting as seal between the two sides of the drape.

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: 7951077
    Abstract: A method and instruments for performing breast augmentation mammaplasty in a patient are provided. The method includes making an incision to gain access to an area underneath the breast of the patient, and providing a retractor including a shaft and a tubular member connected to the shaft. The tubular member includes a hollow endoscope guide portion and a generally flattened blade portion, where the endoscope guide portion transitions into the blade portion such that an end of the blade extends beyond an end of the endoscope guide. The method further includes inserting the retractor at least partially through the incision to aid in placing a breast implant within the patient.

  • Publication number: 20100240961
    Abstract: A surgical retractor includes a first component and a second component. The first component includes a ring structure and a conical outer wall. The ring structure has a first opening and defines a first plane. The outer wall forms a second opening in communication with the first opening and extends below the ring structure at an acute angle with respect to the first plane. The second component includes a top structure and conical inner wall. The top structure has a third opening and defines a second plane. The inner wall forms a fourth opening in communication with the third opening and extends below the top structure at an acute angle with respect to the second plane. The top structure of the second component is disposed at least partially inside the ring structure of the first component such that the second component is rotatably adjustable with respect to the first component.

  • Patent number: 7686492
    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.
