Use

Switching on

The master function Basic positions when switching on Power switch on. What happens: • The power switch and the 5V and ML diodes on the side of the control unit light up • Both zooms travel to the basic position 8 • Both focusing drives travel to the basic position • The zooms are not coupled: Surgeon ● (red) and surgeon ▲ (blue) use their zooms separa tely. The diodes at ● (red) and at ▲ (blue) do not shine.

In the master function, the two zooms are coupled and are controlled by one of the surgeons. The zooms are linked and disconnected by pressing the key Z MASTER on the footswitch or handswitch or directly on the microscope. • Switch once The diode at ● shines. Surgeon ● (red) uses the zooms. • Switch twice The diode at s shines. Surgeon ▲ (blue) uses the zooms. • Switch three times No diode shines. Basic position (see page 11). Whenever the master function is switched, both zooms travel to the basic position 9.

Using the coupled (master) mode • either surgeon ● (red) or surgeon ▲ (blue) can use the zoom • each surgeon can focus separately • both surgeons can control the XY movements • the focus/XY speed is proportional and depends on the master zoom (see page 13). Using the non-coupled mode: • each surgeon can zoom and focus independently of the other • both surgeons can control the XY movement • the focus/XY speed is only proportional on one side (see page 13).

Use

Zoom and focus, footswitch Controlling zoom and focus The arrangement of the functions on the footswitch can be changed in accordance with your requirements. Ask your Leica consultant.

Z

F

Activate zoom (Z) and focus (F). Adjustment speeds for focus and zoom (see page 13).

Z

F Zoom Using the non-coupled mode (see page 11), each surgeon can zoom independently of the other. The magnification set by each user can be read off within the range 5× to 25×. The figure assumes that 10× eyepieces and an f=100 mm objective are used (see optical data on page 36).

Basic zoom position When the key Z MASTER on the footswitch or handswitch or directly on the microscope is pressed, both zooms automatically return to the basic position 8. Both zooms always travel automatically to the basic position: • when the instrument is switched on • whenever the master function is switched.

12

Leica M680 / Ref. 10 705 117 / Version B

Focusing The focusing drive is nondirectional and has no upper or lower limits. The two surgeons use their focusing drives independently of one another. Basic focus position When the key RESET on the footswitch or handswitch or directly on the microscope is pressed, the focusing drive automatically returns to the basic focus position. The focusing drive always travels automatically to the basic position: • when the instrument is switched on • whenever the RESET key is pressed.

The tilt of the footswitch can be set by turning the two spindles

Handgrips You can use the sterilizable handgrips to position the surgical microscope precisely. Sterile controls (see p. 21)

Use

XY-movements

Adjustment speeds

Never tilt or swivel the microscope when the swingarm is folded up. With the system in either coupled or uncoupled mode, the XY-movements can be performed by either surgeon.

Basic speeds The adjustment speeds for zoom (ZOOM SPEED), focus (FOCUS SPEED) and XY movement can be set with the knobs on the control unit.

For adjustment speed, see page 13. You can control the XY-movements • with the joystick (detachable) on the footswitch • with the four keys on the handswitch. In an emergency, the XY movements can be carried out manually: • Remove the two dust plugs (see diagram below) • Insert the Allen key supplied into the openings and tilt and swivel the microscope

Proportional speeds The focus and XY movements become slower with increasing magnification, but the actual speed depends on the basic speed initially selected (see above). In uncoupled mode the speed is proportional on one side only: • in the basic microscope position 1 on the side ● (red) • in the microscope position 2 on the side ▲ (blue). On the other side, focus and XY change in accordance with the basic speed chosen. In coupled mode the speed is proportional on both sides and depends on the magnification selected by MASTER.

Use

Microscope positions When turning the microscope, be careful not to damage accessories such as the TV camera. Basic microscope position 1 • The lamp housing and the control panel must face the stand (index 1 in front).

Changing to microscope position 2 Example: Gynaecology First phase of operation is carried out in basic microscope position 1 (p. 14). Second phase of operation is carried out in microscope position 2: • The surgeons change sides • Release the articulation brakes • Turn the microscope 180° anticlockwise (lamp housing away from stand, Index 2 in front). This makes it unnecessary to re-equip the microscope, because “the two surgeons bring their own personal outfits.”

Selector in position 1 • The microscope is individually equipped for each surgeon: Stereo module, interpupillary distance, eyecups, spacing rings, dioptric settings.

Selector in position 2 The footswitch no longer needs to be repositioned.

Use

Stereo modules, tube adapter, binocular tube

Binocular tube with variable angle of observation 0°–180°

Assembly: See page 30 Stereo modules Each of the two surgeons can choose either a short or a long stereo module in accordance with the surgical discipline, the microscope outfit, and personal preferences. Example 1: Narrow operating table, symmetrical field of operation: Short/short stereo modules

Possibilities for adjustment • Choice of two viewing heights • Viewing angle continuously variable within the range 0°–180°.

0°–180°

0°–180°

Example 2: Broad operating table, asymmetrical field of operation: Long/short stereo modules

Example 3: Broad operating table, symmetrical field of operation: Long/long stereo modules

Interpupillary distance Set your interpupillary distance as follows: • Look into the eyepieces and displace the tubes of the binocular with both hands until you see a single circular field

Scale Read off the interpupillary distance from the scale.

-30°

+30°

Tube adapter, rotatable ±30° If, because of the microscope configuration, the binocular tube tilts sideways, you can level it up again with this tube adapter: • Release clamping screw (b). • Turn binocular up to 30° to the left or right. The binocular tube is secured to the tube adapter by means of the clamping screw (a).

Leica M680 / Ref. 10 705 117 / Version B

Recommendation: User list Draw up a list of users, to include personal requirements such as interpupillary distance, dioptric settings and have the microscope adjusted accordingly for each user in turn.

15

Use

Wide-field eyepieces for spectacle wearers

Illumination

Fitting: See page 30 Recommendation: See page 15

The field of view stays fully illuminated during the zooming procedure and the image-side brightness remains constant. This avoids tiring repeated adaptations to changes in light intensity.

If you work without spectacles and want closer eye contact: • Unscrew eyecup If you work with spectacles: • Do not fit spacing rings • Fold back the flexible eyecups if you need the full working distance.

22 mm

Eyepoint To position your eyes at the right distance from the eyepieces (22mm), proceed as follows: Bring your eyes slowly towards the eyepieces until you see the full field of view.

Adjusting the dioptric settings: • Set the dioptric adjustment within the range from +5 to –5 in accordance with the values given in the user list. Refer to page 17 for an explanation of how these values are determined. Each user need follow this procedure only once. Set the dioptric values exactly in order to maximize the optical advantages of the LEICA M680

Switching on the illumination • Turn on the power switch. The 5V and ML diodes at the side of the control unit shine.

• Use the rotary knob to switch on the light and to adjust the brightness.

Switching off the illumination • Use the rotary knob to switch off the light

Quick-change lamp mount If a bulb fails during the operation, turn the wheel to bring the second bulb into position. The warning lamp shines as a reminder to insert a new bulb later (page 31).

Filters Both users can slide into the beam path a filter holder carrying a KB12 daylight filter or a VG9 green filter.

Use

Adjusting the dioptric setting C Adjust the dioptric setting 6 Zoom position 5. 7 Do not look into the eyepieces Turn the eyepiece mounts fully anticlockwise (+ direction). This position corresponds to +5 diopters.

The dioptric correction is to be carried out precisely for both eyes. Only then will the image stay in focus throughout the zoom range (= parfocal). Each user need follow this procedure only once. Draw up a list for all users. A Preparatory work • Power switch on (page 16) • Light on (page 16) • Set interpupillary distance (page 15) • Eyepiece diopter settings zero (page 16) • Double iris diaphragm OPEN (page 22) • RESET: basic focus position (page 12)

E Eyepiece with graticule Prepare as in section A. Then: • Turn the eyelens mount of the eyepiece containing the graticule fully in the '+' direction. • Look into the eyepiece and slowly turn the eyelens mount in the '–' direction until you see the graticule sharply imaged. • Go straight to section B on page 17. Adjust the setting of the eyepiece without graticule.

Never put your fingers in the fork of the swingarm when the safety hook is not engaged.

Do not adjust the setting of the eyepiece which contains the graticule

Locking the swingarm Always lock the swingarm: • during transport • when changing accessories.

• Pull out the retaining pin • Engage the safety hook. If necessary, raise or lower the swingarm slightly in order to align it with the safety hook

Unlocking the swingarm Always hold the surgical microscope firmly if, when disengaging the safety hook, you are not sure whether or not the swingarm is balanced (page 15). To release the swingarm: Push the counterlever upwards until the retaining mechanism clicks into position. If the safety hook is not easily released, raise or lower the swingarm slightly.

18

Leica M680 / Ref. 10 705 117 / Version B

Use

Adjusting the movements as required Balance the swingarm each time the accessories are changed Always balance before the operation Never change accessories or attempt to rebalance when the microscope is over the field of operation

BALANCE

•

Always tighten the braking knobs completely: • when re-equipping • for transport.

The three joints on the stand have braking knobs which can be adjusted for all stages from total freedom to total immobilization.

The 1100N gas spring (no. 433826) in the swingarm carries loads of up to 23.5kg (see page 21)

When properly balanced, the surgical microscope can be moved vertically on the swingarm through 60cm without drifting.

The braking knob with positioning handle serves to retain the microscope in position 1 or 2 (page 14).

60 cm

Rebalancing after fitting accessories • Lock the swingarm • Tighten all braking knobs • Fit the accessories • Hold the microscope with one hand. With the other, release the safety hook. See whether the swingarm drifts • Turn the tension adjustment knob until the swingarm is balanced. Tension scale: Low loading = low figure.

Leica M680 / Ref. 10 705 117 / Version B

The orange knob keeps the horizontal arm in the perforated plate and may only be opened when the equipment is first installed.

19

Use

Transport, positioning at the operating table, rest position Transport Important: Adhere scrupulously to the following directions. This will prevent the swingarm from moving sideways out of control and perhaps causing the floor stand to tip over. • Release the securing bolt and engage the safety hook • Slacken the articulation brakes and fold up the swingarm as shown in the picture • Tighten the articulation brakes.

• Put the footswitch into its holder • Pull out the power cable from the socket and fold it up • Release the footbrakes by pressing on the foot levers • Use the handles to move the stand to its working location • Now press the footbrakes to engage them.

20

Leica M680 / Ref. 10 705 117 / Version B

Positioning the stand at the operating table For maximum mobility: • the pivotal point on the extension arm must be over the field of operation, and • the articulation of the swingarm must be at a slight lateral angle. Rest position • Lock the swingarm as described above, fold it, and tighten the articulation brakes • Place the footswitch into its holder • Fit the dust caps and the dust covers.
