What is Endoscopy? Minimally invasive surgical procedure Minimally invasive surgical procedure “Keyhole” or “seamless” surgery “Keyhole” or “seamless” surgery Allows surgeons to peer into the body and examine organs in situ Allows surgeons to peer into the body and examine organs in situ Also widely used as a diagnostic procedure Also widely used as a diagnostic procedure

The View

The Endoscope Uses fiber optics and powerful lens systems Uses fiber optics and powerful lens systems Illuminates and provides a view of the interior of joints Illuminates and provides a view of the interior of joints Rigid or Flexible Rigid or Flexible Different variations for viewing different organs Different variations for viewing different organs

The Rigid Endoscope

Rod Lenses

Endoscope to Video Micro-camera attached to eyepiece and image viewed on a monitor Micro-camera attached to eyepiece and image viewed on a monitor Uses Charge-Coupled Devices (CCD) Uses Charge-Coupled Devices (CCD) - Capture and store image data - 2D array of individual elements that can store an electric charge - can respond to as high as 70% of the incident light

Charge-Coupled Device

Light Sources Tungsten filament lamp Tungsten filament lamp halogen reflector lamp halogen reflector lamp - optimal use of light Rare-earth xenon lamp Rare-earth xenon lamp - high intensity light - true color display (xenon daylight effect)

The Flexible Endoscope Bending radius of approx. 15mm Bending radius of approx. 15mm Two fiber optic cables Two fiber optic cables - one is a light conduit (incoherent) - second is used for image transmission (coherent) Image fiber Image fiber - image resolution of approx pixels per square mm.
