This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his or
her own expense. You are cautioned that any changes or modifications not
expressly approved in this manual could void your authority to operate this
equipment.
All interface cables used to connect peripherals must be shielded in order
to comply with the limits for a digital device pursuant to Subpart B of Part
15 of FCC Rules. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
■ Mode of operation: Continuous
■ Protection against electric shock: Class I
2.1 Light emission risks
Retinal blue light and Near-UV emission risk.
► Do not stare at the lamp emission area during operation.
► Minimize exposure to eyes and skin.
► Use appropriate shielding.
► Make sure that no light from the DSM enters the patient’s eyes.
2.2 Fluorescent surgery
► Only use fluorescent agents that are approved for the planned applica-
tion.
► Danger of injury to the eyes due to possibly hazardous UV light. Do not
look at the DSM illumination, minimize exposure to eyes or skin, and
use appropriate shielding.
► Use the lowest comfortable light intensity.
► Ensure that no tissue damage is caused by excessive illumination inten-
sity.
► The room lighting impairs the visualization of fluorescence. For surger-
ies using the DSM fluorescence modules, operate in a darkened room,
if possible.
► Always perform a functional test before using the fluorescence mod-
ules, see Chapter 6.4.1. Use the reference cards to check whether the
fluorescence medium can be excited for the DSM wavelength range
and whether it emits fluorescent light of sufficient intensity.
Note
As in almost all diagnostic procedures, false-positive and false-negative
results can occur in the fluorescence-based digital overlay. Evaluation by
the user based on other methods may be necessary.

3. Product description
The Aesculap DSM is a freestanding, digital surgical microscope in a lookover configuration. The DSM does not utilize traditional microscope binoculars within the field of use and is intended to be an alternative to traditional optical microscopes. The DSM software is a component of the
medical device.
The main components of the DSM system are:
■ 3D flat panel display 1 – live surgical view
■ Touchscreen 2 – control interface
■ Robotic arm 3
■ DSM head 4 – 3D camera, illumination, and handle controls
■ Medical-grade cart 5 with embedded computers
■ Footswitch 6
■ Visualization software
■ Sterile drape
3.1 Robotic arm
The robotic arm is a six-jointed arm that supports the DSM head. Its
touch-guided movement allows the user to manipulate it through the
workspace. The robotic arm may be controlled via the handles, footswitch,
or touchscreen. On the 3D display, the robot state indicator shows the current state of the robotic arm. The robotic arm workspace is illustrated
below.
2.6 Footswitch PV014
► Keep footswitch within a range of max. 10 m to the receiver.
► Do not place the footswitch in or near strong magnetic fields.
► Do not use more than four wireless systems in the same area.
The footswitch is regularly powered by three alkaline batteries of type C
“Baby” (IEC-LR 14), which are placed behind the backside battery cover.
► If they need changing, the terminal must be switched off first in order
to rule out any unintended triggering of functionality.
► Only use footswitch with the specified batteries or backup cable.
► To prevent the footswitch from battery leakage, remove battery from
the case during long periods of non-use.
► Never touch the battery contacts and the patient at the same time.
The maximum mechanical load which the operating elements may be subjected to is max. 1350 N.
The integrated accelerometer prevents an accidental actuation of switching element if the inclination passes 35°.
► Only use footswitch on a firm, even (horizontal) surface.
When using the backup cable:
► When connecting the backup cable, always ensure that connecting ele-
ments (plugs) are clean.
► Ensure that the plug connections are not subjected to mechanical
loads.
► Do not subject backup cable to excessive pulling, pressure or bending.
Do not drive over cable.
► Always perform function test in combination with the DSM when the
device is switched back on.

3.3 DSM cart
The images acquired by the DSM head are delivered to the system computer (EPU) in the cart. This is a special-purpose computer, optimized to
process the images for storage, manipulation, and stereoscopic display.
The signals generated for display employ the Digital Video Interface (DVI),
delivering high resolution and high refresh rate stereoscopic display
images to the display devices. The DVI signals can be delivered to display
devices with DVI or HDMI cable connections.
The system computer is also fitted with a 2 TB storage drive or larger that
stores at least 100 hours of 3D HD videos. The videos can be immediately
accessed for playback due to real-time compression of the video stream as
it is recorded. The compressed video files can easily be transferred to external storage for backup and archival and to free space on the internal storage drive.
The cart also holds a second computer controlling the robotic arm.
3.3.1 Emergency stop
The robotic arm emergency stop is located at the top of the cart. The
robotic arm movement is always under the control of the operator.
► If there is a malfunction and the robotic arm moves in an unintended
way, first attempt to press the Protective Stop button on the touchscreen.
► If the touchscreen does not respond, use the emergency stop to remove
power from the arm and cease all movement.
Note
When the emergency stop is pressed, the DSM head may move up to 3 cm
(depending on position) due to mechanical brakes locking into place.
