The first lens set, the reflector set, the second lens set and the fiber-optic connector are sequentially arranged along a light-emitting path of the first LED in a light-coupling configuration, so that light rays emitted from the first LED are coupled into an optical fiber by the fiber-optical connector. By implementing the minimal incision surgical light source module, the light rays emitted from the first LED are concentrated and condensed into a light beam after passing through the first lens set, the reflector set and the second lens set, thereby reducing a circumference of the concentrated light beam.

    Abstract: The invention relates to a system for the combined shadow-free illumination of a pre-definable area and for referencing three-dimensional spatial co-ordinates, and to an active or passive referencing system, each in particular for referencing surgical or medical instruments. The system is characterized in that at least two cameras and the light source (operation lamp) are held together such that the optical signals detected by the cameras, for referencing three-dimensional spatial co-ordinates in the area illuminated by the light source, can be evaluated. Since the field of view of the light source, in its conventional use, is not obscured or only negligibly obscured, this field of view can simultaneously be used for optical navigation by the cameras held together with the light source. In accordance with the invention, the cameras are automatically aligned optimally for optical navigation. The cameras can be rigidly or flexibly connected to the light source.

  • Patent number: 6086228
    Abstract: In accord with one aspect of the invention, an apparatus for illuminating and magnifying an object in a sterile field for observation is provided. A holder is mounted at one end of a base assembly. A magnifying lens is mounted to the holder and defines a field of vision. A light is attached to the holder by an attaching means in a predetermined spatial relationship with the lens such that the light directs a beam of light into the field. A method is provided for illuminating and magnifying an object in a sterile field without contaminating the sterile field. The base assembly and the holder are sterilized. The base assembly is positioned in the sterile field. A sterile pack containing the light in a sterilized condition is opened and the light is moved into the sterile field. The light is inserted into the opening of the holder. The light is actuated and provides a light beam. The magnifying lens is removed from a sterile pack and moved into the sterile field.

  • Patent number: 5803905
    Abstract: A surgical camera assembly and method for visually producing an operative field with enhanced focal illumination is disclosed as including a retaining assembly operably disposed in connection with a light source. Preferably, the retaining assembly provides a sterile surface for orienting the light source in relation to the operative field and includes a means for retaining a first end of camera lens. Removably disposed in operable engagement with the retaining assembly, the camera lens comprises an elongated body and a variable focus and zoom capability for producing visual images of the operative field. The elongated body of the camera lens is removably introduced within a channel formed in the body of a housing assembly. In preferred relationship, the housing assembly provides a sterile surface for manually adjusting the variable focus and zoom capability of the camera lens for purposes of enhancing the visual images of the operative field produced by the lens.

  • Patent number: 5774271
    Abstract: A lamp assembly includes a condensing lens group disposed at one end for collecting and collimating a light from a light source, an exit lens group at the other end of the assembly, including at least one objective lens element for projecting an illuminated light spot at a predetermined distance, and an iris disposed between the condenser lens group and the exit lens group having a variable opening for varying the size of the illuminated light spot between a minimum and a maximum spot diameter at the predetermined distance. The invention allows the illuminated light spot to be focused for at least two separate iris positions at the predetermined distance by allowing relative movement between the objective lens element and the iris to provide enhanced edge definition and illumination uniformity.

  • Patent number: 5718666
    Abstract: A light-conducting bougie consisting of an elongate flexible member operable for conducting light from the proximal end of the bougie to the distal portion thereof. The light-conducting bougie is made from a substantially homogenous, optically transparent polymer being flexible and operable for the transmission of light. The bougie is particularly useful for transilluminating tissue within a body. In operation, the distal end of the bougie is inserted into a hollow tissue such as the esophagus by passage through the mouth. Illuminating light from a light source enters the proximal end of the bougie and is conducted to the distal portion thereof to exit the bougie and transilluminate the surrounding wall of the organ or structure. The present invention provides an improved bougie wherein the intensity of the portion of light directed radially outward from the distal end portion of the bougie is increased without the addition of material scattering centers to the polymeric body.

  • Patent number: 5683350
    Abstract: A portable hand-held transluminating wand is disclosed which includes a hand grip portion containing the power source and an illumination source at a narrow terminating end. The illumination source is enclosed by a slide-on transparent cover which is shaped to permit insertion into a patient's mouth and placement against the roof of the mouth without discomfort. The translucent cover is tinted red to selectively provide light of a desired bandwidth beneficial to translumination of human tissue. The cover is clear in the region to be placed in contact with the roof of the mouth so that the light emitted in this region is not diffused but remains directed toward the roof of the mouth to facilitate translumination and frosted elsewhere to inhibit light leakage from the patient's mouth when closed about the device. The wand is constructed with a multi-position switch which permits the illumination source to be turned off and on through levels of illumination.

  • Patent number: 5588952
    Abstract: A thin flexible probe that combines illumination and aspiration includes a rigid, two-section housing for accommodating a flexible fiber optic cable and a flexible aspiration conduit. The fiber optic cable terminates at a distal end in an angle of less than 90 degrees relative to its longitudinal dimension so as to emit light in a radial direction through a transparent cover, which forms part of the first section of the housing. The aspiration conduit is connected in fluid communication with an aspiration tip, which forms part of the second section of the housing. A flexible tubular body surrounds the fiber optic cable and aspiration conduit and is sealed to the housing.
