  • an electrically-energised light source such as one or more LEDs
  • LEDs LEDs
  • a current delivered along a cable extending rearwardly along the endoscope In order to provide sufficient illumination it is usual to provide several such LEDs or other sources, which increases the overall size of the device. Alternatively, to keep within a given size, a smaller video camera could be used but with possible increased cost and lower quality.
  • These electrical light sources generate a certain amount of heat in use, which can be a problem, such as in medical applications.
  • the light source could be located at the rear end of the endoscope, away from its viewing tip and light from the source supplied via a bundle of illumination fibres.

  • the light guide may have a coating along the major part of its length of an opaque, optically-reflective material.
  • the light guide may have a forward end surface treated to increase transmission of light through its surface.
  • the light guide may have a rear end with an outer curved surface treated to increase transmission of light through the surface.
  • the illuminating light guide may be provided by an annular component extending within the tubular member, the electrical cable extending through the annular component.
  • the tubular member may be of an opaque plastics material and the light guide be a sleeve of an optically transparent material.
  • the light guide may be deformed radially inwardly at its forward end to increase the amount of light emerging from a flat end of the light guide.
  • the apparatus preferably includes a connector arranged to be fitted on the rear end of the tubular member to make both electrical connection with the electrical cable and optical connection with the light guide.
  • the connector may include a plurality of inwardly-facing light sources arranged to transmit light into the light guide.
  • the apparatus may include a display unit on which an image from the video imaging device is presented and an electrical cable extending from the display unit to the connector.

  • the system includes video bougie apparatus in the form of a tracheal bougie or introducer 1 and utilisation means in the form of a display unit or monitor 2.
  • An electrical cable 3 extends from the monitor 2 and is terminated by a combined electrical and optical connector 4 that, in use, is connected to the rear end 5 of the bougie 1.
  • the connector 4 includes both conventional electrical contact elements that make removable connection with an electrical cable 13 extending along the bougie I and a light source that makes optical connection with a light guide extending along the bougie in a manner to be described in more detail later.
  • the bougie 1 comprises an outer hollow tube or support 10, a video camera unit 1 1 mounted at the forward, patient end 12 of the tube and the electrical cable 13 extending rearwardly from the camera unit to the rear end 5 of the tube.
  • the tube 10 is typically about 720mm long (about twice the length of a typical endotracheal tube) with a circular section about 5mm in diameter, although other sizes could be used. In its natural state the tube 10 is straight apart from a short, preformed Coude tip portion (not visible) at its patient end 12 extending at an angle of about 40° to the remainder of the tube. The tube 10 is bendable and slowly resumes its straight shape if left.
  • the tube 10 differs from previous bougies in that it is made of an optically-transparent plastics material such as polyurethane.
  • the tube 10 is formed with a narrow bore 17 along its length within which the electrical cable 13 extends.
  • the camera unit 11 has a reduced diameter forward portion 18, which forms an annular recess 19 between the outside of the unit and the inside of the tube 10.
  • the curved outer surface 20 of the forward portion 18 is coated with an optically-reflective layer 21.
  • the recess 19 is filled with an optically-transparent potting material 22 both to seal the camera unit 11 in the bougie 1 and to form an optical interface with inside surface of the tube 10.
  • the forward end 12 of the tube 10 is rounded and forms a smooth continuation with the end of the potting material 22.
  • the forward facing surface 23 of the tube 10 and potting material 22 is treated to increase the transmission of light through the surface.
  • the curved, external cylindrical surface 24 along the length of the tube 10 may be coated with an opaque, optically-reflective material 25 or otherwise treated to prevent light escaping along this surface, thereby maximising the amount of light emerging from the forward end surface 23.
  • any coating 25 is removed from an annular band 26 around an outer curved surface of the tube and this region may be treated, such as by roughening, to increase the transmissivity of light through the wall of the tube.
  • the band 26 aligns with an annular region 27 around the inside of the forward end of the connector 4 in which are mounted a ring of inwardly-facing light sources 28, such as LEDs. In this way, the maximum amount of light emitted by the light sources 28 is transmitted through the band region 26 into the wall of the tube 10.
  • the connector 4 also includes conventional electrical contact elements (not shown) that are arranged to make electrical connection in a conventional manner between individual wires in the cable 13 and the cable 3 extending to the monitor 2.
  • the rear end 5 of the bougie 1 in effect, provides an electrical and optical connector for mating cooperation with the connector 4.
  • the video bougie 1 is used to introduce an endotracheal tube 30 to a patient's trachea. This is done by connecting the rear end 5 of the video bougie 1 to the connector 4 and inserting it into the trachea while monitoring the image on the monitor 2.
  • the connector 4 is disconnected to enable the patient end of the endotracheal tube 30 to be slid along the bougie.
  • the connector 4 can be reconnected to view the final stage of insertion of the endotracheal tube and confirm its correct location.
  • the video bougie 1 is withdrawn by pulling rearwardly from the rube 30.
  • the construction of the video bougie according to the present invention enables an effective illuminating light guide to be provided without the need to reduce the size of the camera unit. By locating the light source outside the bougie, larger and more powerful light sources can be used to maximise illumination and without any appreciable heating effect within the patient.
  • the arrangement also enables the rear end of the bougie to have a low profile so that relatively small diameter endotracheal tubes can be slid along the bougie after removing the connector.
  • the illuminating light guide of annular section need not be provided by the outer tube itself but could be provided by a sleeve separate from the outer tube in the manner shown in Figures 4 and 5, in which various components are the same as or similar to those of the bougie shown in Figures 2 and 3.
  • the outer tube 40 of the bougie 1 is made of a conventional opaque plastics material and the bougie has a separate transparent light guide sleeve 41 of annular section that is a close fit within the bore 42 of the outer tube.
  • the light guide 41 need not be made of a solid transparent material but could be provided by a bundle of low-cost optical fibres arranged in a tubular configuration with the fibres extending longitudinally and terminating at opposite ends in a ring of cable ends.
  • the light guide 41 extends to the forward end 43 of the tube 40 where the tube is necked in slightly to a smaller diameter causing the forward end of the light guide sleeve 41 also to be deformed radially inwardly slightly. This ensures that a maximum amount of light emerges from the flat end of the guide sleeve 41 rather than from its sides, so that as much light as possible is projected forwardly axiaily of the bougie.
  • the space between the inside of the light guide 41 and the outside of the reduced diameter portion 44 of the camera unit 45 is filled with a potting compound 46. This seals the camera unit 45 and the light guide sleeve 41 in the forward end of the tube 40.
  • one of more transparent regions 46 are formed in the wall of the tube 40 to allow light from sources 28 in the connector 4 (which may be of the same kind as described in respect of the arrangement in Figures 2 and 3) to pass into the side of the light guide 41.
  • the transparent regions 46 may be windows cut through the tube 40 and filled with a transparent material.
  • the region 47 of the outer curved surface 48 of the light guide 41 aligned with the transparent regions 46 is surface treated, such as by roughening, to increase light transmission into the guide.
  • This latter arrangement has the advantage of enabling existing opaque materials to be used to make the bougie so that the device retains the mechanical handling characteristics of conventional bougies without an imaging capability.
  • the arrangement at the rear end of the bougie by which light is transmitted from the connector is slightly more complex than with the arrangement in Figures 2 and 3.
  • the continuous, tubular sleeve form of the light guide 41 might alter the flexibility of the bougie. It would be possible to provide a guide of a different form, such as of a spiral shape. This could enable a more rigid material to be used without compromising the mechanical handling properties of the bougie. This could allow a wider choice of materials to be used for the light guide, which could include materials with increased transparency or higher refractive index.
  • Both arrangements of the present invention enable a relatively high level of illumination to be provided at the viewing end of the apparatus without any increase in its diameter and without any significant heating effect at the viewing tip. It will be appreciated that the invention is not confined to medical applications but could be applied to endoscopes for use in industrial applications or the like. .
