1 Application and description
The OS3 operating unit is used in surgical procedures to the
anterior and posterior segments of the eye. It performs all
essential functions including irrigation and aspiration,
ultrasound Phaco, bipolar diathermy for haemostasis and
coaptation of conjunctiva, diathermic capsulotomy, diathermic
tissue cutting and the drive of vitrectomy instruments. The
unit can be supplemented with the VC830200 module for
carrying out vitreo-retinal procedures.
IMPORTANT!
1. Patients with heart pacemakers or pacemaker electrodes
may be at risk in that the functioning of the pacemaker may
be impaired or the pacemaker itself damaged. If in doubt, the
cardiology department must be consulted.
2. The functioning of other electro-medical equipment may be
affected during the operation of bipolar diathermy,
capsulotomy and vitrectomy cutters.
The unit actuates and controls companion instrumentation
within the performance limits chosen by the operator and as
set on the control panel. A foot pedal effects fine adjustments
within the pre-set limits. The unit is extremely easy to use.
Frequently used equipment settings can be stored and
recalled.
The unit may only be used with the Oertli instruments
recommended and supplied by the manufacturer (see
Section 13).
The unit may only be operated by trained personal. Correct
settings are the responsibility of the surgeon.
The unit is not suitable for surgical procedures outside the
eye. If in doubt, contact the manufacturer.
2 Points to note and hazards
IMPORTANT
Please read these instructions very carefully before using the
apparatus for the first time!
IMPORTANT!
Before connecting the unit, check that the voltage shown on
the rating plate is the same as that of the operating room!
IMPORTANT!
Where high-frequency diathermy, HF-cut or vitreous cutting is
used simultaneously with physiological monitoring equipment
on the same patient, any monitoring electrodes must be
placed as far as possible from the diathermy points. Needle
monitoring electrodes are not recommended. Monitoring
systems incorporating high-frequency current limiting devices
are recommended in all cases.
IMPORTANT!
The correct choice of instrument settings is the responsibility
of the surgeon! Values given in this instruction manual are
suggestions only.
IMPORTANT!
Only instruments and accessories supplied by the
manufacturer and listed in Section 13 may be used!
IMPORTANT!
Only persons authorised by the manufacturer may carry out
modifications and repairs, otherwise the proper functioning of
the unit may be impaired.
IMPORTANT!
While operating in diathermy or HF-cut mode, the instrument
tip must be monitored carefully. The pedal must be released
immediately as soon as tissue begins to overheat
excessively.
IMPORTANT!
All accessories must be checked regularly! Diathermy cables
in particular should be checked for possible damage to the
insulation.
IMPORTANT!
The unit must never be used in areas containing inflammable
anaesthetics!
IMPORTANT!
The cart with the tray fully stretched out can tip over if
inclined more than 6°! The cart must only be moved when the
tray is fully folded and stored.
IMPORTANT!
The operator is responsible for compliance with EN ISO
60601-1:2007.

3 Control panel
The display and adjustment area
All settings for the operation of the OS3 operating unit can be
undertaken using the control panel (pre-settings are made
using ParaProg. See Section 10). Visual displays serve to
show the current operating state of the unit and the current
values. The buttons respond to light pressure, which can also
be applied using a sterile swab or the special sterile operating
pen (VE850003) available from the manufacturer.
Depending on the stage of the operation or the setting of the
operating pedal, certain buttons will be blocked. This feature
offers increased protection against improper use.
The execution of a button command is accompanied by
corresponding changes in the display field. There is no
change in the display when a blocked button is pressed.
The control panel can be separated from the unit and placed
in a sterile bag for use in the sterile area. To do so, lift and
disengage the control panel from below. Alternatively, an
additional control panel VE 830025 or a remote controller VE
830020 can be connected to socket M3.

Auxiliary functions
RESET button
Can be pressed at any time, and brings the unit to an
immediate stop. Ultrasound time is reset to zero. Reset of the
Ultrasound time also after installation of the cassette.
The RESET button restarts the internal processor and is thus
an escape button in a situation where, for some reason,
normal operation is no longer possible.
AUX button
Used (button held down) to adjust the volume of acoustic
signals (SOUND) and voice messages (VOICE). Also adjusts
the IOP indicator (bottle height).
VOICE button
Repeats or stops the current voice message. The scope of
information given can be defined in ParaProg.
PREOP button
Initiates the filling and rinsing function, and stops the
procedure if pressed again. Completes the procedure with a
phaco test if PREOP is started when in phaco 1, 2, 3
operating mode.
TEST button
Starts the phaco test when the unit is set to phaco 1, 2 or 3,
or activates the connected vitrectomy instrument during
button depression, if the unit is in VIT A, VIT B or VIT PN
mode.
NOTE: If not willingly activated PREOP or Phacotest also
can be interrupted by pressing pedal with the heel.
Then the display shows the message “PREOP
discontinued” or “Phaco Test discontinued”.
4 Control pedal
The control panel is used to regulate the I/A system and all
instruments. It must be connected to the pedal connection
socket (M1) on the rear of the unit. The control pedal can be
moved vertically (downwards) and
horizontally (sideways) and has four switching elements,
which, for safety reasons, can only be accessed by lifting the
foot.
The vertical plane
Fig. 1
4
Reflux
0
1
The vertical range – from zero to the fully depressed position
– is divided into a maximum of three ranges: irrigation,
aspiration and instrument activation. These three ranges lie
between positions 0, 1, 2 and 3. If the pedal is pressed
slowly, the settings 0-3 can be felt as a slight resistance. This
resistance can be changed in ParaProg (low, medium, high).
The pedal is brought to position 4 by pressing with the heel,
and this position is always used to activate reflux.
The number of positions and the amount of travel between
them can be changed in ParaProg. This is described in detail
in the ParaProg user manual, VV016013E.
The vacuum is always off in position 0.There is no suction,
and the instruments are inactive.
The service engineer can adjust the firmness of the pedal
(resistance to movement).
The horizontal plane
In the horizontal plane, the pedal can be moved to the left
and right. The pedal can be moved horizontally from any of
the vertical positions, i.e. even when the pedal is depressed.
If duallinear operation is selected in ParaProg (see Section
10), the chosen instrument is controlled linearly by moving
the pedal to the left (i.e. the power of the instrument
changes in proportion to the deflection).
Moving the pedal to the right switches between the
multimode memories of the function just used (e.g. phaco 12-3 etc.).
ParaProg (see Section 10) can be used to specify whether 2
or 3 memories should be available.
In ParaProg (se Section 10) you can invert the assignments
of left and right of the horizontal movement to right and left.
Switching elements
The two round switches (heel switches) can be operated with
the heel (the pedal does not have to be in the zero position)
to change the infusion pressure (bottle height) or air pump
pressure. Pressure is always reduced with the left heel
switch, and increased with the right heel switch.
The two switches on the pedal grip (TOP switch) are
positioned so that they can only be activated after the pedal
has been returned to the zero position (foot raised).
TOP left
Switches between the basic functions (selector) e.g. I/A,
CAPS, Phaco, etc. Each surgeon can enter his preferred
sequence in ParaProg.
