Light Cables

 border=Email this page


Optic cables are made up of a bundle of optical fibres glass thread swaged at both ends. The fibre size used is usually between 10 to 25 mm in diameter. Whilst they have a very high quality of optical transmission, they are very fragile. In fact, progressively as they are used, some optical fibres break. The loss of optical fibres can be seen when one end of the cable is viewed in daylight. The broken fibres are seen as black spots.

Insist on the best.  Once a light cable start to break throw it out.  NEVER PENNY PINCH when it comes to image.  Image quality is vital so insist on the best.  Remember, that to access the gain button on your image, the light cables must be compatible to the stack system. Keymed cables are very, very expensive, but if you have their system, they are vital.

Maintenance of cables:

  • Handle carefully
  • Avoid twisting
  • After completing the operation disconnect the light source from the laperoscope and allow it to cool down.  Finally disconnect from the light source.
  • Never look directly at a lighted light source. The intensity of light can damage the retina.
  • Periodically clean the end of the crystal cable with with an alcohol swab.
  • Similarly, clean the outer plastic covering of the with a mild cleaning agent.
  • Never place the cable on or under drapes, or next to the patient if it is connected to an illuminated light source. The heat may cause burns to the patient or ignite the drapes.
