Core
The da Vinci Si Core is the system’s central connection point where all system, auxiliary
equipment, and AV connections are routed. (See Chapter 4 System Connections for details.)
Instrument Control Box (ICB)
If installed, the following information is applicable. The ICB is a hardware upgrade installed by
an Intuitive Surgical field engineer on the lower shelf of the Vision Cart. It powers certain
functions of advanced EndoWrist instruments such as the Vessel Sealer. Intuitive supplies
instructions to use the ICB as part of the instructions to use the applicable instrument.
Illuminator
Lighting for the surgical field is provided by the Illuminator (Figure 2.16). The light from the
Illuminator is delivered to the endoscope via a fiber optic light-guide cable and projected
onto the surgical site through the endoscope. The Illuminator has front panel controls for
increasing or decreasing the light output and turning the lamp on or off. (See 7.3 Working
with the Illuminator Controls on page 7-14 for details).

Endoscopes
The da Vinci Si HD Vision System uses a 12 mm or 8.5 mm 3D endoscope with either a straight
(0°) or angled (30°) tip. (For more detail specific to the 8.5 mm endoscope, see Appendix F:
8.5 mm Endoscope for the da Vinci Si System.) Light from the Illuminator is sent down the
shaft of the endoscope (Figure 2.17 and Figure 2.18) via fiber optics and projected onto the
surgical site. Heat from the fiber optics helps to minimize fogging at the endoscope lens. The
