(2). If the motorized zoom function becomes active of |
|
|
its own accord (e.g. travels to the stop), set emergency |
|
|
switch (7) to the emergency mode (position 2). |
page 210 |
3Failure of the focusing function:
•Manually adjust the working distance using focusing knob (3). If the motorized focusing function becomes active of its own accord (e.g. travels to the stop), set the emergency switch to the emergency mode (posi-
tion 2) |
page 211 |
4Some of the magnetic brakes are blocked:
•Switch off power switch (4). As soon as the blue screen appears (approx. 10 sec), switch the system back on.
The OPMI functions (zoom, focus, light and magnetic brakes) are available again after approx. 15 seconds. The computer and touchscreen, however, are disabled.
If the magnetic brakes are still blocked:
•Hold the microscope on its body (not on the handgrips) and position it manually by overcoming the braking ef-
fect. |
page 215 |
5Failure of the touchscreen:
•Do not under any circumstances touch the touchscreen, since this can result in changes to settings and
parameters. Zoom, focus, illumination and brakes can |
|
still be operated. |
page 212 |
6Error messages in the data injection system:
•System errors are displayed in the microscope's integrated data injection system. You can delete these messages by acknowledgement using the joystick of
the right handgrip (pushbutton) or the touchscreen. page 212

Warning!
For safety reasons, the system must only be used when correctly balanced. Despite the autobalance function, it may happen in exceptional cases that the surgical microscope is not correctly balanced.
With an incorrectly balanced system, brake release may lead to uncontrolled movements of the suspension system. For this reason, the balancing procedure and the subsequent test must not be performed above the patient and only at a safe distance from other persons and instruments.
To check correct balancing of the system, loosen the brakes while holding the microscope tightly at both handgrips. If the system has been correctly balanced, the surgical microscope can be moved almost effortlessly.
Repeat the autobalance procedure, if required.

Activities in the data network may interfere with the system. We therefore recommend that you disconnect the system from data networks before surgery.
The network connector must be adequately contact-protected, e.g. made of plastic material.
The cable and connector of the network connection must at least comply with Cat-5e EIA/TIA-568A-5, i.e. the more recent Class D values from ISO/IEC 11801:2002 or EN 50173-I:2002.
Data transmitted by the system into the data network or data available in the data network risk to be corrupted or transmitted incompletely. Therefore, no liability can be accepted for the correctness of the data.
The operator of the data network is responsible for compliance with the legal requirements regarding data security and for the protection of personal rights.
If you operate this system within the patient area* in conjunction with devices from other manufacturers which do not comply with the IEC60601- 1 standard, you must ensure that either the third-party devices are powered via an isolating transformer, or that each of them is connected with the central ground system via an additional ground terminal (potential equalization).
The leakage current may increase if the system is connected with other devices. The resulting new system must comply with the EN 60601-1-1 standard (Safety Requirements for Medical-Electrical Systems).

•Make sure that all ”Requirements for operation” are fulfilled.
•Go through the checklist (see chapter "Operation“ or the index).
•Re-attach or close any covers, panels or caps which have been removed or opened.
•Please pay special attention to labels on the unit (warning triangle with an exclamation mark, warning labels and notes).
•Do not cover any ventilation openings.
•Using the locking pedal on the base, secure the stand in position. Make sure that the stand is stable and cannot roll away.
•Make sure that nothing obstructs the touch-sensitive area of the touchscreen. Prevent objects from exerting pressure on the touchsensitive area of the touchscreen.
•Any kind of radiation has a detrimental effect on biological tissue.This also applies to the light illuminating the surgical field. Please therefore reduce the brightness and duration of illumination on the surgical field to the absolute minimum required.
•Never use xenon illumination for ophthalmic procedures.
•Make sure that no xenon light enters the patient's eyes.
•The illumination intensity required depends on the type of application involved. Make sure that no tissue damage is caused by excessive illumination intensity.
Only systems from authorized manufacturers may be connected and used on the navigation interface of OPMI Pentero (see page 80). Authorized manufacturers are companies or institutions with which Carl Zeiss Surgical has concluded an Open Interface Contract and for which the use of the integrated navigation interface with data injection system has been licensed.
Please observe the user manual for the connected system.

The OPMI Pentero is equipped with a powerful xenon illumination system. Excessive illumination intensities may lead to third-degree burns, if used improperly.
The risk of burns is influenced by several different factors:
–The wavelength range is limited by filters to the visible range between 400 nm and 700 nm (between 400 nm and 780 nm in the IR 800 mode only). These filters remain stable over a very long period of time and cannot be exchanged by the user.
–With increasing age of the light source, the actual illumination intensity delivered at the respective setting decreases. When the light source is finally replaced, the illumination intensity increases again to the high, original value.
–The selected intensity of the light source is a major factor for the risk of injury. It should always be set to the minimum required for the surgical procedure to be performed.
–The size of the illuminated field influences the risk of injury in two different ways:
–If the illuminated area has a large diameter, skin areas are illuminated that are not closely monitored by the surgeon and are not sufficiently irrigated. These areas are particularly prone to injury. Injuries can be prevented by adjusting the diameter of the illumi- nated field to the smallest size needed for the respective proce- dure.
–Reducing the illuminated field increases the intensity because the light becomes more focused. The light intensity should therefore be reduced, if possible, as soon as the diameter of the illuminated area is reduced.
–A long surgical procedure increases the risk of injury, in particular if a standard procedure takes considerably longer than usual.
–Injuries in the peripheral area can be prevented by covering this area with wet, sterile gauze.

–You should also take into account that some areas of the body may be more sensitive than others.
–Certain preparations of the surgical field, local vasoconstrictive medications and incision drapes may also result in a higher risk of injury.
–The general condition of a patient's health may contribute to the risk of injury.
–The skin type may also play a major role in this respect.
–Certain medications affect the sensitivity to light.
Due to the large number of different factors involved and the lack of scientific publications on this topic, Carl Zeiss cannot provide guidance on acceptable intensities and exposure durations. However, the OPMI Pentero has several features that can help the user to reduce the risk of burns:
–The start value of the light intensity can be set to a low value (page 134).
–The spot function permits you to reduce the size of the illuminated field to the area observed during the procedure (page 66).
–You can then set the light intensity to the value required for the procedure using the buttons on the handgrip or foot control panel. Please note that the use of the spot illumination system increases the intensity as the size of the illuminated field decreases. Therefore adjust the light intensity after changing the diameter of the illuminated field.
–If the system features Automatic Light Field Limitation, this function has been activated at the factory and should not be deactivated.
In systems without automatic light field limitation, the Light Intensity Control function has been activated at the factory and should not be deactivated.
–The magnification level is usually increased during a procedure, leading to a darker image and thus necessitating an increase in illumination intensity. If zoom-dependent brightness control has been activated, it automatically compensates for this loss in image brightness. (page 134)
–Switch off the light when the microscope is not used, and make sure that it is not pointed at unprotected bare skin.

Please note that most burns affected the skin around the incision. The most important measures to prevent burns are the reduction of the area illuminated by spot illumination and covering the peripheral area with wet sterile gauze. The area of the incision should be constantly irrigated.
Final remark
Carl Zeiss recommends:
–Reduce the illumination of the surgical field to the extent required for the patient's safety and for clear microscopic visualization.
The illumination intensity is preconfigured (factory settings) in such a way that a warning is displayed on the touchscreen and in the data injection system when the threshold value of 25% is exceeded, informing the user of possible tissue damage when the light intensity is too high.
–Please note the warning and safety notes in the "Light“ configuration menu (page 134).
–Reduce the exposure time to a minimum.
These measures should help the surgeon to reduce the risk of phototoxic injury of the patient.
•Switch off the system at the power switch after every use.

Safety switch
The brakes will be locked if a spring or cable breaks. You can nevertheless finish surgery, as you can still move the surgical microscope by applying slight force.
Uninterruptible power supply (UPS)
A UPS is integrated in the system to ensure correct operation in the event of short power failure. It powers the electronic system and the touchscreen, but not the light source.
Messages:
–Line power failure: in the event of line power failure, the system is supplied for a short time. If no power is available for a prolonged period, the system is shut down.
–Line power is back: the user is informed when line power is back (Power OK), and all subsystems are re-initialized. This process may take a few seconds.
Note:
In general, the system is ready for operation after power-up. A continuous beep indicates extreme discharging of the USP. In this case, the system should not be powered up for at least five minutes. After this time, you can power up the system again for charging the UPS. For the initial startup or after long rest periods, we recommend the following: leave the poweredup system connected to line power for approx. 12 hours in order to fully charge the UPS.
The system automatically tries to remedy problems in the control software. After several unsuccessful attempts, the system executes a PC reset to restart the application. This restart runs automatically in the background and restores the full functionality of the system within approx. 2 minutes. All major basic functions of the OPMI Pentero remain fully available to the user during this time (operation of focus, zoom, light, brakes, motorized XY movement).
Backup illumination
The lamp module contains two identical lamps. If lamp 1 fails, a quick-ac- tion changer ensures that the light guide is supplied by lamp 2. The lamp change does not impair the surgeon in his work.
