Technical Overview2

Figure 2.20.1 shows the assembled system. The quality and thus usefulness of the visual information available for the surgeon depend on several parameters:

• Number and quality of fibers dedicated to image transmission

• Focal distance of the handpiece's lens(es)

• Distance of the handpiece from the target

• Angle of illumination

1 Autoclave.

2 While description of the equipment and its operational setup are not among the goals of this book, this brief exception is made here to facilitate understanding of the technology.

Fig. 2.20.1 An assembled endoscopy system.1 The fiber optics transmission probe is connected to a three-chip CCD camera equipped with an ultrasensitive automatic shutter. The probe is fully autoclavable.2 Universal connections are used so that the probe can be connected to endoscopic cameras as well as light and laser sources already available in the OR. This more than offsets the original costs of the technology

2 As required by WHO rules. This is especially important in traumatology, where surgery can be time-consuming and with an increased risk of endophthalmitis.

• Magnification

• Resolution of the camera

• Size of the operative field and of the targeted image

• Attributes of the light source and the distribution of the light

• Size, quality, and settings of the video monitor
