Do not use any rotatable tube dovetail mounts when operating the sur-
gical microscope with a connected navigation system. If mounts of this
type have been attached to the microscope, they must be carefully
locked in their central positions (tighten the knurled screw for rotation).
Requirements on the antenna design (non-Zeiss antennas)
•
The antenna manufacturer must confirm that his antenna has been
tested and certified for operation with the respective Carl Zeiss surgi-
cal microscope on a suspension system in accordance with the re-
quirements specified in the Carl Zeiss interface description
"Navigation Interface for Carl Zeiss Surgical Microscopes".
•
The following requirements, in particular, apply to the antenna:
– The surgical microscope with accessories and the antenna must
not exceed the admissible total weight (see label or the chapter
"Technical data").
– The antenna must not project over the bottom edge of the micro-
scope body in the direction of the surgical field.
– The antenna must neither obstruct the movement and adjustability
of the accessories which can be used on the surgical microscope
(usually a stereo coobservation tube, a camera adapter, a face-to-
face tube for spinal surgery, a laser micromanipulator) nor collide
with these accessories.
– The antenna configuration must be implemented in such a way
that the localizer camera can always "see" the diodes or trackballs
when the surgical microscope and its accessories are in their usual
positions.
– When the system's internal antenna wiring is used, the EN60601-
1-2 standard (electromagnetic compatibility) must be complied
with.
– The output power of the LEDs or infrared LEDs (IRED) must al-
ways comply with the IEC 60825 laser safety standard, even in the
event of cable defects.
– The failure of one or several LEDs of the antenna may impair nav-
igation or lead to navigation failure. Take the necessary precau-
tions.
