Field of navigation

Warning: Visually inspect the emitters before use. Do not use an emitter that is

visibly damaged.

Emitter Quick Reference Guide

Warning: Do not use the side-mount emitter or the flat emitter in ambient (room)

temperatures greater than 30°C (86°F). Exceeding this temperature limit could
result in navigational inaccuracy or patient or user harm from excessive
temperatures.

Warning: If the flat emitter is left in the storage bin during system use, it can reach

56°C (133°F). In this condition, allow the flat emitter to cool for five minutes
outside of the storage bin before patient contact.

Caution: For procedures performed with the flat emitter, a surgical table with a

radiolucent table top is recommended. If the surgical table has a metal frame or
metal side rails, position the flat emitter at least 5 cm (2 in) away from the metal.
Positioning the emitter closer may result in reduced navigational accuracy and
volume.

Caution: If the surgical table to be used with the side-mount emitter has a metal

frame or metal side rails, position the side-mount emitter at least 25 cm (10 in)
away from the metal. Positioning the emitter closer may result in reduced
navigational accuracy and volume.

™

Caution: Refer to the StealthStation

system level manual and procedure pocket

guides for additional instructions, warnings, and cautions.

Side-mount emitter navigation field

The side-mount emitter produces a low-energy magnetic field that encompasses the
emitter. Minimize the amount of metal placed in this field. The navigation field, the
portion of the magnetic field that is appropriate for navigation, begins 8 cm (3 in)
from the emitter face and has a cubical volume of approximately 31.0 cm x 46.0 cm
x 46.0 cm (12.2 in x 18.1 in x 18.1 in) (length x width x height). For best results,
place the patient in the center of the navigation field.

Low-energy magnetic field: Minimize the amount of metal in this field. Metal objects
such as instrument stands, equipment carts, surgical lights, and viewing screens in

this area will reduce the navigation field size.

Note: This navigation field size is based on testing with a fluoroscopically

radiolucent surgical table with non-magnetic metal rails 3 cm to 6 cm tall by 1
cm to 3 cm wide (1.2 in to 2.4 in tall by 0.4 in to 1.2 in wide) and a 25 cm (10 in)
separation between the metal rails and the side-mount emitter.

Flat emitter navigation field

The flat emitter produces a low-energy magnetic field that encompasses the emitter.
Minimize the amount of metal placed in this field. The navigation field, the portion of
the magnetic field that is appropriate for navigation, begins 5 cm (2 in) from the
emitter face and extends approximately 40.0 cm x 40.0 cm x 37.5 cm (15.7 in x

15.7 in x 14.8 in) (length x width x height). For best results, place the patient in the
bottom center of the navigation field.

Low-energy magnetic field: Minimize the amount of metal in this field. Metal
objects such as instrument stands, equipment carts, surgical lights, and viewing

screens in this area will reduce the navigation field size.

Emitter Quick Reference Guide

Surgical tables and emitter selection

Refer to the following table for information about using the flat emitter or side-mount
emitter with different types of surgical tables. Before surgery, try the emitter setup
with the surgical table to be used, and make sure that the software can track the
instrument and the patient reference frame throughout the range of locations
required for registration and navigation. Refer to “Refining emitter position” on page
15 for more information.

emitter

Flat emitter or

Flat emitter or
side-mount emitter

Details

Fully radiolucent tables do not have any metal
around the patient head and torso.

Using a fully radiolucent surgical table instead of
a fluoroscopically radiolucent table will
significantly extend the navigation field above
the flat emitter and will slightly extend the
navigation field in front of the side-mount
emitter.

Fluoroscopically radiolucent tables do not have
any metal directly under the patient head and
torso.

When using the flat emitter, a separation greater
than 5 cm (2 in) between the emitter and the
metal rails on the table will significantly extend
the navigation volume above the flat emitter.

When using the side-mount emitter, a separation
greater than 25 cm (10 in) between the emitter
and the metal rails on the table will slightly
extend the navigation volume in front of the side­mount emitter.

Side-mount emitter
(variable outcomes)

Details

Non-radiolucent tables and ENT chairs have
variable outcomes with EM navigation. The flat
emitter is not recommended for use with non­radiolucent tables and ENT chairs. Use of the
side-mount emitter may be possible. Position
the side-mount emitter away from metal in the
surgical tables and chairs for best results.

Setting up the side-mount emitter

Connect the side-mount emitter cable to the emitter port on the main
cart localization I/O panel.

Warning: Do not place the side-mount emitter in contact with the

patient because the emitter temperature may reach 48°C (118°F).

Caution: Visually inspect all accessory devices before use. Do not use accessory

devices if they are visibly damaged.

Caution: Procedures performed with the side-mount emitter require a surgical bed

featuring side rails because the arm assembly that supports the emitter
connects to the side rails.

Cranial procedures

Set up the side-mount emitter where it will not interfere with the surgeon’s access to
the patient during surgery.

1. Secure the Short Bedrail Adapter (9732566) to the rail of the surgical table.

Note: If the surgeon is right-handed, set up the emitter on the left-hand side.

For a left-handed surgeon, set it up on the right-hand side.
