Introduction The internal weight of the stand balances the weight of the surgical microscope and the fitted accessories.

Function Balancing system and brakes The Leica M520 MS3 surgical microscope consists of the Leica M520 surgical microscope and a floor stand. The stand and the Leica M520 surgical microscope are balanced using the balancing system. All movements which must be carried out during the surgery require only minimal force. Two directions of movement, A and B, are balanced out at the Leica M520 surgical microscope.

There are six electromagnetic brakes on the Leica M520 MS3 surgical microscope, which block movement of the stand and surgical microscope:

Movement C is balanced out at the microscope carrier.

• Up/down in parallelogram (0) • Front horizontal (1) • Horizontal at column (2) • In C slide of microscope carrier (3) • At the A/B slides of the surgical microscope (4) • In rotatable joint (5)

Introduction Illumination The illumination of the Leica M520 MS3 surgical microscope consists of a main illuminator and an emergency illuminator. They are located in the basic tower. The main illuminator is a Xenon lamp, and the emergency illuminator is a halogen lamp.

1

The light of the main and emergency illuminators is carried through the stand to the Leica M520 surgical microscope via a fiber-optic cable. If the main illuminator fails, the plug of the fiber-optic cable is switched over to the emergency illuminator.

Activating and positioning movements 1

➩Press and hold the ALL FREE button (5). The Leica M520 surgical microscope can be moved, swung, tilted, lifted and lowered in all directions as desired. ➩Release the ALL FREE button. The Leica M520 surgical microscope remains precisely in the desired position.

➩Turn the rotary knob (3) with the black arrow to adjust the Leica M520 MS3 surgical microscope along the traverse axis. If the rotary knob is turned clockwise, the air bubble moves to the right. The Leica M520 MS3 surgical microscope is adjusted when the air bubble is located directly in the middle of the display (1). If the axis position is very skewed, the air bubble does not move until the rotary knobs (2 and 3) are turned in the desired direction for some time.

Operation ➩Press the selector button (1). The movements set in the section entitled «Changing settings for handgrips” (Page 27) can now be positioned.

Always allow the main and emergency illuminators to remain lit for at least five minutes, otherwise the lighting capacity will be quickly reduced. ➩Switch on main illuminator at the switch (4). ➩Adjust the brightness of the main illuminator with the regulating knob (3) if necessary.

Switching on the illumination Caution The light source in this unit may be too bright at shorter focal lengths for surgeon and patient. ➩Start with light low and turn up till surgeon has an excellent optical image. Explanation light quantity The variable working distance of the M520 optics goes from 207–470 mm. The system is designed to have full light at 470 but not at 207 mm. According to the inverse square law Ev=Iv/d2 a constant light increases from 470 mm to 207 mm by a factor of 510 %. (Ev = illuminance; Iv = intensity; d =distance from the light source) Therefore a microscope with shorter working distances requires less light than longer working distances. A good practice is to start with the light low and to turn it up until the surgeon has an excellent optical image.

Switching from main illuminator to emergency illuminator Warning Failure of the illumination can be dangerous for patients! ➩If the main illuminator fails, switch to the emergency illuminator immediately. ➩Switch off main illuminator at the On/Off switch (4). ➩Pull fiber-optic cable from the outlet (2) of the main illuminator and insert it into the outlet (6) of the emergency illuminator. ➩Switch on emergency illuminator at the On/Off switch (7). ➩Adjust brightness of the emergency illuminator with the regulating knob (5) if necessary.

Explanation heat from light The heat produced from this xenon light source is filtered to not allow heat from non visible light (above 700 nm). However all white light contains heat. Excessive use of white light can cause over heating in the field of tissue and metal objects. A good practice is to start with the light low and to turn up until the surgeon has an excellent optical image.
