20 Safety

• Make sure that the instrument has been switched off before you change the xenon lamp module. When switched on, the ignition system generates high voltage.

• The xenon illumination system is a high-intensity light source which if used improperly - can cause thermal injury to skin or tissue. Keep the exposed tissue moist and provide sufficient irrigation. Carefully monitor the effects of the illumination on the tissue, in particular in the following cases:

– during prolonged procedures on skin and tissue using objective

– during procedures on tissue with a low blood supply,

– with high brightness settings of the xenon lamp.

• Since the xenon lamp provides high light intensity and generates light with a spectrum similar to daylight, it must not be used for ophthalmic applications.

lenses with a short focal length (short working distance),

• 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.

S7 floor stand

• Using the brake tabs on the base, secure the stand in position. Make sure that the stand is stable and cannot roll away.

S7 ceiling mount with lifting column

• The lifting column is used to move the microscope into position for sur-

gery prior to the surgical procedure.

Do not constantly move the lifting column up and down, since a thermal cut-out will then automatically switch off the drive motor. If this occurs, the lifting column cannot be moved again until the motor has cooled down.

Sensera surgical microscope on S7 suspension systems

Intended use

The OPMI Sensera surgical microscope on S7 suspension systems has been specially designed for use in ENT surgery, i.e. the overall system meets the special requirements of this discipline.

The system is intended for use in hospitals, clinics or other human medicine institutions.

The system must only be operated by physicians, nurses and other OR staff who have undergone appropriate training and observe the instructions of the user's manual. The installation conditions and the use of the system must meet microsurgical requirements:

– low vibration

– clean environment

– avoidance of extreme mechanical stress.

Description of the system

The apochromatic optics of the microscope provide superb optical quality. The microscope image displays optimum contrast and excellent detail recognition along with outstanding depth of field and maximum 3D perception. The 1:6 ratio zoom system allows the magnification of the overall system to be set as required by the surgical procedure.

You can use the surgical microscope with or without an integrated video camera. Depending on your requirements, you can choose between a PAL or an NTSC video system.

Suspension systems

The S7 floor stand is a suspension system for Zeiss surgical micro-

scopes. It comprises a suspension arm, a carrier arm, a stand column and a stand base. A maneuvering handle attached to the stand column is used to move the stand and to attach the foot control panel. The stand column is provided on its left and right with cable supports for winding up cables before the unit is relocated.

G-30-1434-en OPMI® Sensera on S7 Suspension Systems Issue 10.0

Printed on 30. 01. 2009

Description 35

The stand base is extremely easy to move on its four casters. It has been designed in such a way that high stability is ensured even with unfavorable loading of the stand. The locking tabs permit you to reliably secure the floor stand in position at the site of use.

Note: As the stand is very easy to maneuver, there is a tendency to underestimate its weight. Therefore, move the stand slowly and carefully!

The S7 ceiling mount with rigid column is a suspension system for Zeiss surgical microscopes. It comprises a suspension arm, a carrier arm, a ceiling column and a ceiling flange.

The S7 ceiling mount with lifting column is a suspension system for Zeiss surgical microscopes. It comprises a suspension arm, a carrier arm, a ceiling flange and a lifting column. This motorized lifting column permits the viewing height to be perfectly matched to the surgeon's requirements.

The carrier arm of all suspension systems contains the control unit with all electrical supply systems required for the control of a motorized surgical microscope. You can control the motorized functions using the handgrips, or via a foot control panel (option). A light guide (fiber optic illumination) directs the light from the lamp housing in the suspension system to the surgical microscope.

The suspension arm of all types of suspension system permits almost effortless positioning of the surgical microscope. The spring force of the suspension arm can be varied in a range from 6 to 14 kg, permitting reliable balancing of the microscope even with accessory equipment attached. The downward movement of the suspension arm can be limited using an adjustable positioning aid.

A control panel allows the adjustment of user-defined settings such as the zoom, focus, brightness and video settings, and the programming of the configurable handgrip buttons.

The SpeedFokus autofocus option permits you to select features (ROI, region of interest) in the image of the surgical field and to rapidly focus on them automatically or at the press of a button.

USB memory option An optional USB port permits you to save image data in the JPEG or TIFF format on a USB memory stick. Image data can also be read from a USB memory stick and displayed on a connected monitor. The saved image data can also be deleted.

Warning!

If the xenon light source is used, the unit must not be used in ophthalmic applications. Severe injury to the patient's eye is possible.

Widefield eyepieces with magnetic coupling

Note: When you remove these eyepieces from the tube, please note that they are fitted with a magnetic coupling. When mounted, the eyepieces display a very weak magnetic field, so that the usual rules for the handling of magnets must only be observed with eyepieces which have not been mounted on the microscope:

• Do not place the eyepieces close to instruments where there is any risk of magnetization.

• Do not place the eyepieces on sensitive electronic units such as infusion pumps, cardiac pace-makers, measuring instruments or magnetic data carriers such as disks, audiotapes and videotapes, or credit cards.

• Always store eyepieces not used in their original packaging.

1 Eyecup

Always adjust the eyecups in such a way that you can see the full field of view.

– Viewing with eyeglasses: Screw in the eyecups all the way. – Viewing without eyeglasses: Screw out the eyecups until you

see the full field of view.

2 Diopter adjustment ring

The eyepieces provide ametropia compensation between -8 D and +5 D. Eyeglass wearers who perform surgery wearing their glasses set the diopter adjustment ring to 0 D. Turn the ring until you have obtained the optimum setting. An integrated brake holds the ring in the position set.

3 Diopter scale

Illumination system

Two different types of illumination are available for the suspension system.

1 Halogen illumination

The halogen light source is equipped with an illumination system for fiber illumination. The lamp housing contains a backup lamp which is automatically swung into the illumination beam path when the first lamp fails.

2 Xenon illumination system

The xenon light source is equipped with an illumination system for fiber illumination. The xenon lamp generates light whose spectrum resembles that of natural daylight. Regardless of the brightness setting, the color temperature of the light always remains the same. Normal daylight film without any additional conversion filters can therefore be used for photographic documentation. The lamp module contains two xenon lamps. The second lamp is used as a backup lamp which can be manually swung into the illumination beam path when the first lamp fails. You have to pull out the lamp module all the way before being able to swing in the backup lamp.

Warning!

The xenon illumination must not Make sure that no xenon light enters the patient's eyes during paranasal sinus surgery. Use the spot illumination and cover the eyes of the patient.

Warning!

The xenon lamp has a limited service life of 500 h.

If used beyond its maximum service life, the xenon lamp may explode.

Change the xenon lamp in good time.

The xenon illumination system has been designed for fiber illumination. The xenon lamp generates light whose spectrum resembles that of natural daylight. Regardless of the brightness setting, the color temperature of the light always remains the same. Normal daylight film without any additional conversion filters can therefore be used for photographic documentation. The lamp housing contains two xenon lamps. The second lamp is used as a backup lamp which must be swung into the illumination beam path should the first lamp fail.

Warning!

If the xenon light source is used, the unit must not be used in ophthalmic applications. Severe injury to the patient's eye is possible.

Caution:

Do not cover the ventilation grid! For example, drapes could be covering the grid. This can cause the lamp modules to overheat and lead to lamp failure.

Structure of the menus

Notes: – If no entry is made for about 30 seconds, the preceding menu will au-

tomatically reappear.

– The data you have entered or changed will not be saved until you

press the OK button or the enter button, or when the preceding menu appears after approx. 30 seconds because no further entries have been made.

Start of menu

After you have switched on the system, the software is loaded. The growing size of the ZEISS logo indicates that this loading process is still in progress. The release number is displayed in the top left corner. The system then performs a self-test. After successful completion of the test, the "User Selection" menu is automatically displayed.

User menu

The User menu comprises one standard profile and three other user profiles. When a user profile is selected, the system imports the settings stored under this profile, e.g. focusing speed, zoom link setting, zoom speed and handgrip settings. The stored start values ("Start at") for the magnification factor, the focus position and the brightness are automatically set. The three user profiles are used to adjust these settings for different users.

When the system is started up for the first time, the Standard User is displayed; at every subsequent start-up, the user active last is displayed.

Notes: – The Standard User profile allows the adjustment of settings, but these

settings cannot be saved (fixed factory settings).

– In the Standard User profile, all "Start at" fields are deactivated. No bar

is displayed; it is not possible to adjust any settings.

SpeedFokus autofocus option The SpeedFokus autofocus option permits you to select and automatically focus on a feature in the ROI (region of interest, measuring field) in the image of the surgical field. The SpeedFokus autofocus function is based on the evaluation of the video image contrast: during focusing of the microscope's Varioskop optics, SpeedFokus continuously determines the video image contrast in the selected ROI. In this way, SpeedFokus controls the microscope's Varioskop optics and adjusts it to the point of maximum contrast, corresponding to the point of maximum image definition.

Autofocus menu The Autofocus menu offers you the following functions for selection:

– ROI, on/off: activating / deactivating the ROI display

– ROI Size, smal/medium/large: selecting the ROI size

– ROI Position: branching to the AF - ROI Position submenu to define

the ROI position

– Camera Position, left/right: entering the orientation of the external vid-

eo camera.

– Advanced Settings: branching to the Advanced Settings submenu to

enter the technical data of the external video camera.

Notes: – The "Camera Position left/right" and "Advanced Settings" functions

are only offered for selection if your system is equipped with an external video camera. If you have an integrated video camera, these fields remain blank.

– As long as you are entering any settings in the Autofocus menu or its

submenus, the ROI is displayed as a square frame in the video image on the monitor. A few seconds after your last action, the frame disappears from the screen.

Menu item "ROI, on/off" The position and size of the ROI are displayed on the video monitor in the form of a square frame. Use the "ROI on/off" function to activate or deactivate this display on the video monitor.

Menu item "ROI Size, small/medium/large" Permits you to select the ROI size. Three different ROI sizes are available for selection: small (20x20 pixels), medium (36x36 pixels) and large (50x50 pixels). The default setting for the Standard User is the large ROI. You can change the size of the ROI, but the change cannot be saved for the Standard User. For specific users, the ROI size can be set and saved for each user as required.

Submenu "AF - ROI Position" This submenu permits you to define the ROI position within the microscope's field of view.

When you start the suspension system, the ROI is always positioned at the center of the field of view. The ROI is visualized as a square in the graphic display. Use the arrow keys to shift the ROI.

Press the OK button to return to the Autofocus menu. If you do not press any of the buttons, the display will automatically return to the Surgery menu after approx. 20 seconds.

Menu item "Camera Position": If you are using an external video camera, the orientation of the video camera must be known to the SpeedFokus autofocus option.

Note: This function is only available in systems equipped with an external video camera.

Caution:

The video image must have the same orientation as the image in the main eyepieces of the surgical microscope. In addition, SpeedFokus needs the information whether the video camera is connected on the left or right, i.e. whether the beam splitter projects into the main beam path from the left or right, to be able to perform corrections in the right direction during the focusing process.

Submenu "Advanced Settings" Notes: – This submenu is only available in systems equipped with an external

video camera.

– This submenu contains camera-specific settings. These settings only

need to be changed when a different video camera is installed.

– The SpeekFokus autofocus option does not function properly if pa-

rameters have not been correctly set.

The "Advanced Settings" submenu contains the following camera-specific settings:
