Function

Balancing system and brakes

The Leica M500 OH3 surgical microscope consists of the Leica M500 N surgical microscope and the Leica OH3 floor stand.

The stand and surgical microscope are balanced out by the balancing system. All movements which must be carried out during the surgery require only minimal force. The AB swivel movement is balanced out via the A and B pinion.

Movement C is balanced out at the microscope carrier.

The internal weight of the stand balances the weight of the surgical microscope and the fitted accessories (movement D).

Introduction

Leica M500 OH3 / Ref. 10 711 894 / Version -

There are 6 electromagnetic brakes on the Leica M500 OH3 surgical microscope, which block movement of the base and surgical microscope:

• up/down and forward/backward in a parallelogram (0 and 1)

• at base (2)

• in microscope carrier (3)

• at A and B sledges of the surgical microscope (4)

• in rotatable joint (5)

Using the selector switch (Item 10, Page 10) for brakes (XYZ FREE or FOCUS LOCK) at the control unit, two different brake groupings can be selected. The following movements with the surgical microscope can still be performed if the selector switch is located in the FOCUS LOCK position:

The following movements with the surgical microscope can be performed if the selector switch is located in the XYZ FREE position:
