SPECIAL USER ATTENTION
As with the operation of any surgical light, all
hospital personnel should be aware that a certain
amount of care must be exercised to maintain
patient safety and to keep your SKYTRON light
fixture performing at peak efficiency.
To help assure the highest degree of operating
safety for user and patient, SKYTRON has provided precautionary instructions throughout this
manual.
All operating room personnel should be familiar not
only with the proper operation of the SKYTRON
surgical light fixture, but also with the precautionary
instructions associated with its proper use.
Please review the following summary of the important precautionary instructions:
WARNING
Indicates a possibility of personal injury .
NOTE
To prolong bulb life, the sof-star t bulb
protection circuit will cause a slight delay before the bulbs will illuminate
WARNING
Be sure sterile handle is properly secured before using the lighthead. An
improperly installed handle could fall out,
resulting in possible injury to patient or
surgical staff.
WARNING
In the presence of flammable anesthetics, DO NOT allow the lighthead to be
below 60 inches from the floor .
CAUTION
Indicates a possibility of damage to
equipment.
NOTE
Indicates important facts or helpful hints
NOTE
SKYTRON products are guaranteed for
proper performance with the use of
genuine SKYTRON CENTER FOCUS
HANDLES. After market competitive
handles and other disposable handles
will have varying results that could ultimately affect the proper performance
and secure engagement of the center
focus handle. Such applications are at
the discretion of the user to ensure patient safety.
NOTE
All repairs should be made using only
authorized SKYTRON replacement
parts.
Page 5
CAUTION
Use of incompatible cleaning agents will
cause damage to the fixture. Avoid the
use of cleaning solutions which contain
high concentrations of alcohol, ethelene
glycol, phenol, iodophors, or glutaraldehyde based disinfectancts. Staining,
pitting, discoloration and diffuser cracking may occur if these are used.
WARNING
Be sure the power is turned "OFF" and
the bulbs have cooled before changing.
WARNING
NOTE
To extend the life of the bulb reflector
surface, it should not be included in
normal cleaning. It should be cleaned
only if absulutely necessary . Clean gently with a clean, damp, soft cloth and a
mild soap solution. NO abrasives.
DO NOT attempt to remove a bulb by
pulling on the glass surface or end cap .
This may cause the bulb to break off in
your hand.
CAUTION
Halogen bulbs are sensitive to body
oils. DO NOT handle glass surface of
bulb as body oils from your fingers can
create a "hot spot" and may cause the
bulb to burn out prematurely. This can
best be avoided by using the plastic
wrapper that the bulb is packaged in or
a clean cloth wrapped around the base
of the bulb when installing.
The Stellar series surgical lighting system from
SKYTRON features fully adjustable positioning and
focus control for its cool, color-corrected, multiple
bulb, light source. Combinations of vertical positioning and multiple rotational capabilities allow the
single, dual or triple lighthead models virtually limitless positioning within a thirteen foot diameter area
(triple lighthead models).
The fixtures are single point ceiling mounted with a
continuous 360 degree rotation capability at the
ceiling mount end of the radial support ar m. See
figure 1. The balance mechanism which is attached to the radial arm by a vertical support tube,
provides the lighthead an additional continuous 360
degree rotation point. The balance mechanism is
an enclosed spring tension system. This allows
vertical movement of the lighthead while maintaining the lighthead position without drifting. The yoke
provides additional 360 degree rotation points for
lighthead pitch and roll.
The adjustable focus mechanism which optimizes
the light output by superimposing all the light beams
into a single spot can be operated by non-sterile
personnel using the lighthead mounted focus knob .
All lightheads also have a removable, sterilizable,
focus/positioning handle. This allows all final positioning and focus adjustments or changes to be
precisely done by the surgeon. See figure 2.

the handle out to be certain that it is locked (PUSHTWIST-PULL). A distinct click can be heard when
the handle is properly engaged.
4. Adjust the focus by moving either the nonsterile focus knob or the (sterilized) center focus
handle until all of the light beams converge on the
surgical site forming a single bright spot of light.
5. For low angle lighting approach, the lighthead
will move 90° below horizontal. Pull the lighthead
down by the positioning handles or the (sterile)
positioning/focus handle.
WARNING
In the presence of flammable anesthetics, DO NOT allow the lighthead to

General
LIGHTHEAD POSITIONING
To obtain the maximum benefit from your
SKYTRON surgical lighting system, the following
suggestions are offered as a guide for lighthead
positioning. Personnel who are trained in proper
lighting techniques can plan and set up the lighting
arrangements prior to the arrival of the patient. F actors whichshould be considered when
prepositioning surgical lights are:
-Specific procedure to be done
-Patient position during procedure
-Position of surgical team
-Location of instrument trays or tables
-Location of IV stands
-X-ray equipment and personnel
-Anesthesia equipment and personnel
-Angulation and size of surgical cavity
Surgical Table Placement
For most procedures the surgical table should be
located with its center point directly under the light
fixture’s ceiling mount.
The lightheads can be most effectively positioned
by using the following procedures:
1. Grasp the positioning handles on the
lighthead and pull the lighthead down to shoulder
height. Keep the lighthead at approximately a 45°
angle to easily position the support yoke. See figure 6.
SUPPORT
YOKE
POSITIONIN
HANDLE
Pre-Positioning The Lighthead
Surgical light positioning requirements change not
only from procedure to procedure, they also change
from surgeon to surgeon. Final light positioning
and adjustment will be directed or done directly by
the surgeon. The objective of prepositioning is to
require a minimum of final adjustments after arrival
of the patient. The non-sterile focus control should
be located where it can be reached by non-sterile
personnel and the sterile positioning/focus handle
where they can be reached by the surgeon. Use
extreme care when prepositioning lightheads.
Bumping lightheads into one another, into walls , or
other equipment may alter bulb alignment which
affects proper focus adjustment.

installation procedure.
6. Grasp the positioning handles, place the
lighthead at an angle and move the lighthead to its
full up position.

ILLUMINATION TECHNIQUE
Maximum illumination, shadow reduction, and possible obstruction by the surgeon or surgical staff
are also major concerns for lighthead positioning.
The following examples are offered as a basic guide
for lighthead placement for large diameter/satellite,
dual lighthead, or triple lighthead fixtures.
Large Diameter/Satellite Lighthead
Positioning
The large diameter lighthead should be pre-positioned over the surgical site. The satellite can be
used on either side of the surgeon for augmentation and shadow control.
The large lighthead should be positioned perpendicular to the bottom of the surgical cavity.
Head
To illuminate the head area, position the large diameter lighthead radial arm parallel to the table
centerline. See figure 9. Position the lighthead behind the surgeon. Tilt the lighthead to the desired
position using pitch axis movement. This will allo w
the multiple light sources of the lighthead to pass
around the head and shoulders of the surgeon and
at the same time permit adequate head clearance
for the surgeon.
Position the satellite to the left or right according to
surgeon preference. This allows a second light
source to come from another angle which will help
eliminate obstructions or shadows.
Torso Area
For most chest and abdominal procedures, position the large lighthead directly over the surgical
site. See figure 10. Position the radial arm on approximately a 45° angle from the surgical table
centerline. This position will locate the sterile focus/positioning handle on the lighthead where it can
easily be reached by the surgeon. The f ocus control will be where it can easily be reached by nonsterile personnel. Position the satellite lighthead,
depending on lighting needs, to augment the larger
lighthead.
Figure 10.
In some cases such as cholecystectomies and
total abdominal hysterectomies, the surgical cavity may be angled. In cases such as this, the large
lighthead should be angled so that the face of the
lighthead is perpendicular to the bottom of the surgical cavity. See figure 11.
Figure 9.
Tilt the lighthead to position the focus control knob
where it can be easily reached by non-sterile personnel.
Figure 11.
30˚30˚
Some procedures, such as hip pinnings, require
both lightheads to be on the same side of the table.
See figure 12. In this position the lightheads are
behind and adjusted to project light over the head
and shoulders of the surgeon. Both lightheads are
easily reached for adjustment by non-sterile personnel.
Figure 12.
Page 13
Dual 23" Diameter Lighthead Positioning
Fixtures containing dual 23" diameter lightheads
require some special positioning considerations.
The small diameter of the lightheads allows the light
source to be more easily obstructed by the surgical staff. It is very impor tant that the surgical site
remain illuminated even though the head and
hands of the surgeon and the surgical staff may
be directly in the central light beam path. In order
to minimize shadowing,the lightheads
should be positioned so that their light beams are
angled into the surgical cavity. Regardless of the
surgical site, these lights should be positioned to
maintain an angle of approximately 30° about an
imaginary line running perpendicular to the bottom
of the surgical site. See figure 14.
Perineum
The large diameter lighthead should be positioned
at the end of the table for perineal procedures. Locate the radial arm directly in line with the centerline
of the table. Oncethe surgeon has assumed
a seated position, the lighthead can be pulled down,
angled, and adjusted to provide the necessary illumination over the surgeon’s head and shoulders.
See figure 13. The satellite lighthead radial arm
should be positioned approximately 90° from the
other radial arm. Position the satellite lighthead to
the right or left of the large lighthead according to
surgeon preference. In this position, the focus
knobs of both lightheads are located for easy reach
by non-sterile personnel.
Figure 14.
Tilting the lightheads will give a larger light beam
angle. See figure 15. Final positioning and focus
adjustments can be done by the surgeon using the
sterile focus/positioning handles. Focus controls
should be positioned where easily reached by nonsterile personnel.

Triple Lighthead Positioning
T riple lighthead systems will either consist of a large
diameter lighthead with two 23" satellites or three
23" lightheads. There are two basic positioning
strategies that can be used to obtain the best illumination possible. The first is to align all three
lightheads to the centerline of the table with the
large lighthead directly over the center of the surgical site. The second is to cluster the lights in a
circular arrangement over the surgical site with each
lighthead about 120° away from each other. The
whole cluster should be positioned to minimize interference with the head and shoulders of the surgical staff. See figure 16.

Bell-Shaped Cavities
For most surgical procedures the lighthead will be
properly focused with all the light beams converged
in one spot at the bottom of the surgical cavity.
However, in the case of a bell-shaped cavity (for
example - total abdominal hysterectomy on an
obese patient), focusing at the bottom of the cavity
may cause more shadow problems . The focal point
for the light beams should be above the bottom of
the cavity. See figure 17.

Figure 16.
When an angled cavity is to be illuminated, at least
one of the lightheads should be positioned to be
perpendicular to the bottom of the cavity .
For head and perineal work, the lights should be
positioned as they would for a dual system but with
a satellite on each side of the surgeon.
Figure 17.
Beyond the focal point, the light beams spread out
like an inv erted cone and will more ev enly spread
the light throughout the bell-shaped cavity.
Other Illumination Considerations
Close attention to surgical light intensity during the
case as well as good quality general illumination in
the room will help to minimize eye fatigue of surgical personnel.
Dark surgical drapes will help to reduce reflectance.
White drapes should be avoided at all times because of high reflectance.
The use of matte and satin finish instruments and
retractors also helps to reduce eye fatigue.

MAINTENANCE
T o insure proper oper ation and to extend the lif e of
your SKYTRON surgical lighting system, the following preventive maintenance procedures are
recommended.
NOTE
All repairs should be made using only
authorized SKYTRON replacement
parts.
Daily Maintenance
Daily or between cases, the lighthead exterior
should be wiped down with a mild cleaning agent
which will not affect the painted or acrylic parts.
Do not apply or spray cleaning agents directly on
the lighthead.
CAUTION
Use of incompatible cleaning agents will
cause damage to the fixture. Av oid the
use of cleaning solutions which contain
high concentrations of alcohol, ethelene
glycol, phenol, iodophors, or glutaraldehyde based disinfectancts. Staining,
pitting, discoloration and diffuser cracking may occur if these are used.
•Use plexiglass cleaners, DO NOT use alcohol
based cleaners on the acrylic diffusers.
•Always consult with the manufacturer of the cleaning agent for proper application and use. Always
spot test on an inconspicuous area before use.
•Avoid using excessive amounts of spray cleaners near top cover vents. Leakage of fluids into the
interior of lighthead may cause corrosion of electrical components.
•Periodically the filter/diffuser assemblies should
be removed and dusted with a clean cloth or
washed and air dried as a complete assembly.
•DO NOT operate lights without the filter/diffuser
assemblies in place.
Sterilization
Recommended sterilization parameters for
sterilizable handle:
a. Prevac, 270° F, 4 minutes
b. Gravity, 250° F, 30 minutes
c. Flash, 270° F, 3 minutes
Always consult current AORN journal recommendations for proper sterilization procedures.
Adjustments
As part of a regular preventive maintenance program, it is suggested that a check of the various
positioning axes be made to verify correctness of
tension adjustment. If any lighthead drift is noticed,
all that is usually necessary is a minor adjustment.
Readjustment should be made as per the appropriate instructions contained in the Maintenance
and Adjustment Manual. Also, during a scheduled
cleaning of the lighthead interior, lubrication of the
various moving parts is desirable.
•Avoid personal injury. Do not attempt to clean
lighthead unless power is turned off at wall control
and fixture has sufficiently cooled.
Page 16

Bulb Changing
Since SKYTRON Surgical Lights contain multiple
bulbs, it would not normally be necessary to change
a burned out bulb during a surgical procedure. The
loss of one or even three bulbs in a large diameter
lighthead may be completely unnoticed during use.
To replace a bulb , use the f ollowing procedure:
WARNING
Be sure the power is turned "OFF" and
the bulb has cooled before changing.
1. Hold the diffuser/filter assembly with one
hand, loosen the "1/4-turn" screw and lower the
diffuser/filter assembly. See figure 18.
WARNING
DO NOT attempt to remove the bulb
by pulling on the glass surface or end
cap. This ma y cause the b ulb to break
off in your hand.
2. Using caution not to touch the reflector surface, hold the bulb by the base and pull it out. See
figure 19. Slightly working the bulb back and forth
may aid in bulb removal.

of the bulbs as body oils from your fingers can create a "hot spot" and may
cause the bulb to burn out prematurely .
This can best be avoided by using the
plastic wrapper that the bulb is packaged in or a clean cloth wrapped around
the base of the bulb when installing.
3. Holding the bulb by the base, plug it directly
into the socket. Do not touch the glass portion of the
bulb reflector surface with your fingers. This can
best be done by using the plastic wrapper that the
bulb is packaged in or a clean cloth wrapped
around the base of the bulb when installing. Be sure
bulb base is properly seated in the connector to
insure proper focus alignment.
Page 17
A regular program of preventive maintenance will
increase the life of your equipment and keep it
operating at peak performance.
Maintenance can be performed by authorized,
trained maintenance personnel using SKYTRON
authorized replacement parts and service techniques. Ser vice instructions and parts are available from SKYTRON.
Preventive Maintenance contracts are available
through your local SKYTRON representative.
