Carry out a postoperative pacemaker check.

900-400_IFU_V1.0.0.6.17.9_20140-S2-20130604-EN Operating Manual ARC 400 11

2 Safety

2.3.3. Hazard-free patient positioning

Position patients so that they are not touching any metal parts that are grounded or
have considerable capacitance relative to ground (e.g. operating table brackets). If
necessary, place anti-static cloths between the patient and the bedding.

Ensure that the patient does not touch any wet clothes or bedding.
Place anti-static cloths between areas with heavy sweating and skin-to-skin

contact areas on the patient’s torso.
Ensure that the patient is resting on a suitable surface in order to prevent pressure

necrosis.
Drain urine via a catheter.

2.3.4. Correct connection of the HF device

Always ground the HF device to the equipotential rail.
Also observe the requirements in Section 8.6.7 of IEC 60601-1 regarding medical
electrical systems.

Do not use needle electrodes for monitoring.
Attach electrodes of physiological monitoring devices without protective resistors

or HF chokes as far away from the HF electrodes as possible.
Place lines from monitoring devices so that they do not lie on the patient’s skin.
Keep the leads to the HF electrodes as short as possible and position them so that

they do not touch the patient or other leads.
Do not place any objects on the HF device.

2.3.5. Correct use of the HF device

Inadvertent activation of the HF device outside the user’s field of vision can injure
the patient.

Activate the HF device only when the electrode is in your field of vision and you
can quickly deactivate the HF device at all times.

If the HF device is activated inadvertently, switch it off immediately using the on/off
switch.

Take particular care when using a foot switch or manual switch.
Improper preparation, user errors or faults in the HF device can cause damage to

the HF device.
Use the automatic monitoring functions to ensure that the HF device is working

properly. See Section Functional testing, page 26 for information on the auto test
functions.

foot switch or the manual switch.

Ensure that the cables for the foot switch and the manual switch are free from
short circuits and broken leads.

12 Operating Manual ARC 400 900-400_IFU_V1.0.0.6.17.9_20140-S2-20130604-EN

2 Safety

2.3.6. Configuring HF device settings and using accessories

Setting the output power too high can injure the patient. Therefore, before you
increase the output power, ensure that:

 the neutral electrode is attached properly;
 the working electrodes are clean;
 the plug connections are all correct.

Setting the HF device correctly

To prevent inadvertent (thermal) tissue damage during operations on body parts
with small cross sections and in areas with high resistance (bones or joints), use
the bipolar method in these areas.

Set the level of the acoustic signal that sounds when the electrode is activated so
that it is always clearly audible.

Risk of nerve or muscle excitation by low-frequency currents.
During HF surgical operations (especially when an arc is formed), part of the HF
current is converted into a low-frequency current. This current can trigger muscle
contractions in the patient.

To minimize the risk of injury to the patient, set the power and the effect as low as
possible.

Correct use of accessories

Use only insulated accessories.
Check all electrodes for sharp edges and projecting parts before use.
Use only electrodes that are free of defects and in good working order.
Never place active electrodes on or near the patient.

Do not remove hot electrodes from the patient’s body directly after cutting or

coagulation.
Ensure that there is sufficient distance between the patient cables and the cables

of the HF device.
Do not run the patient cable across the patient.

2 Safety

2.4. Product-related safety instructions

Devices manufactured by BOWA are developed in accordance with the current
state of technology and generally accepted safety rules. Despite this, using these
products can lead to risks to the life and health of the user or third parties and/or
damage to the device or other objects.

Use only accessories approved by BOWA, see Section Accessories and
replacement parts, page 134.

Use the device only when it is in free of technical defects and in good working
order and only for the intended purpose, always remaining aware of safety
requirements and risks and complying with this operating manual.

Have malfunctions that can adversely affect safety (e.g. deviations from the
permissible operating conditions) repaired without delay.

Wipe down the HF device only with cleaning agents and disinfectants that are
approved in the country of use for surface cleaning. See Section Disinfection and
cleaning, page 85.

Never immerse the device in water or cleaning agents.
Never boil the device and never disinfect it mechanically.
If any fluids penetrate the device, drain them immediately.
Damage to the device can lead to an undesirable increase in output power due to

improper operation of the device.
Certain units or accessories can cause danger in lower power settings. For

example, the risk of gas embolism in argon assisted coagulation rises, if the hf­power is insufficient for the fast creation of an impenetrable eschar layer on the
target tissue.

2.5. Safe handling (general instructions)

Before each use of the device, check to ensure that it is functioning properly and is
in good working order and connected properly.

Observe the instructions on intended use in conformance with standards (see
Section Fault indications for EASY monitoring , page 84.

During use, always observe and comply with the acoustic signals and/or error
messages of the HF device (see Section Fault indications for EASY monitoring ,
page 84).

The device and accessories may be operated and used only by people who have
the necessary training, knowledge and experience.

Regularly inspect the accessories, especially the electrode cables, endoscopic
accessories and neutral electrodes, for damage to the insulation, proper operation
and expiration date.

Ensure that no instruments are being cleaned when AUTOSTART is activated.
Wear suitable gloves during operations.

14 Operating Manual ARC 400 900-400_IFU_V1.0.0.6.17.9_20140-S2-20130604-EN

2 Safety

Observe the instructions on the use of the neutral electrode in the user
guide and the information on the package of the neutral electrode.

2.5.1. Operation area: avoiding ignition and explosions

Sparks are generated when the HF device is used as intended.
Do not use the HF device in areas where there is a risk of explosion.
Do not use any flammable or explosive liquids.
If the display fails, do not use the HF device any longer.
During operations (e.g. in the head or thoracic regions), avoid using ignitable

anesthetics and gases that support combustion (e.g. nitrous oxide or oxygen) or
extract them using a vacuum system.

Use exclusively non-flammable cleaning agents, disinfectants and solvents (for
adhesives). If you use flammable cleaning agents, disinfectants or solvents,
ensure that they have fully evaporated before using HF surgical equipment.

Ensure that no flammable liquids collect beneath the patient or in body cavities
(e.g. the vagina). Suction and/or flush body cavities before activating the device.

Wipe off all liquids before using the HF device.
Ensure that no ignitable endogenous gases are present.
Ensure that all materials saturated with oxygen (e.g. cotton or gauze) are kept far

enough away from the HF environment that they cannot ignite.

2.5.2. Applying the neutral electrode

In the monopolar HF method, the neutral electrode feeds the current introduced
into the patient’s body at the surgical site back to the HF device.

To prevent a rise in temperature at the current exit point, the following conditions
must be ensured:

 sufficiently large contact surface between the neutral electrode and

the patient’s body;

 high electrical conductivity between the neutral electrode and the

patient’s body.

900-400_IFU_V1.0.0.6.17.9_20140-S2-20130604-EN Operating Manual ARC 400 15

2 Safety

To prevent the patient being burned by the neutral electrode, you must comply with
the following conditions:

 Select the application point for the neutral electrode so that the

current paths between the active and neutral electrodes are as
short as possible and run longitudinally or diagonally through the

patient’s body (because muscles are more conductive in the

direction of the fibrils).

Figure 2-1: Application point of neutral electrode

 For surgery in the thoracic region, do not run the current path

transversely across the patient’s body and ensure that the patient’s

heart is never in the current path.

 Depending on the surgical site, apply the neutral electrode to the

nearest upper arm or thigh if possible, but never closer than 20 cm.

 In the case of self-adhesive disposable electrodes, comply with any

further manufacturer instructions regarding the point of application.

 Ensure that the application area is free of scar tissue, bony

protuberances, surface hair and ECG electrodes.

 Ensure that there are no implants (e.g. bone nails, bone plates or

endoprostheses) in the current path.

 Ensure that no short circuits can occur at the neutral electrode

connection.

 Avoid areas where fluids may collect.
 Use split neutral electrodes with a sufficiently large surface area

(patient age and max. output power during operation have to be
considered).

Before applying the neutral electrode

Shave the area where the neutral electrode will be applied.
Clean the application site, but do not use any alcohol, since it dries out the skin

and increases the contact resistance.
If the patient has poor circulation, massage or brush the application site.

16 Operating Manual ARC 400 900-400_IFU_V1.0.0.6.17.9_20140-S2-20130604-EN

2 Safety

See Section Fault indications for EASY monitoring, page 84 regarding
monitoring of the neutral electrode.

Attach the neutral electrode over the entire contact surface evenly. Secure
reusable neutral electrodes with rubber bands or elastic straps so that they do not

loosen when the patient moves. Ensure that the patient’s circulation is not impaired

(risk of necrosis).
Never use wet clothes or conductive pastes.
Ensure that no liquids (e.g. cleaning fluids, disinfectants, blood or urine) penetrate

between the patient and the neutral electrode.
Do not place the neutral electrode under the patient’s buttocks or back.
Ensure that there are no ECG electrodes in the current path of the HF device.
Check the neutral electrode before and after use for damage and to ensure that

they are working properly.
Replace defective accessories immediately

Example application using a disposable electrode

Remove the protective film and attach the self-adhesive disposable electrode to
the patient. Ensure that the long edge of the disposable electrode faces the
operation site and the electrode is fully in contact with the skin. This avoids
excessive current concentration on the short edge.

Using both hands, press the self-adhesive disposable electrode firmly against the
patient’s skin.

Clamp the electrode tab to the neutral electrode cable.
After the operation, remove the disposable electrode carefully to avoid skin

damage.

With a one-piece neutral electrode

Check the one-piece neutral electrode during surgery.
Ensure that the one-piece electrode is not blocked at the device.

With a split neutral electrode

Apply the split neutral electrode correctly and without any additional objects, as
otherwise the HF device may detect a path between the two sections due to other
objects.

See that the current flows equally to both parts of the split neutral electrode.

 Split electrodes for infants (for use with reduced power)
 Split neutral electrodes

The type of neutral electrode and its contact quality are selected and/or shown in
Neutral Electrode Modes menu.

900-400_IFU_V1.0.0.6.17.9_20140-S2-20130604-EN Operating Manual ARC 400 27

4 Prearrangement

The maximum output power of monopolar current types is reduced to
50 W when a children’s electrode is selected.

NOTE

Risk of incorrect application of the neutral electrode

 Ensure compliance with the specifications for correct attachment of

the neutral electrode with regard to size, adhesive properties and
full-surface contact of the complete electrode.

Figure 4-1: Neutral electrode modes

Faults related to the neutral electrode and possible remedies are shown on the
display, see Section Detecting and correcting faults, page 73.

4.5.2. EASY neutral electrode monitoring (EASY monitoring)

The EASY monitoring function measures changes in the resistance between the
patient and the high-frequency surgery device before and during HF activation. If
necessary, it generates visual and audible alarms to request staff intervention. This
requires using a split neutral electrode with appropriate contact areas and suitable

contact resistance, attached to the patient according to the manufacturer’s

instructions. The EASY system does not monitor the currents through the
individual contact surfaces of the split neutral electrode.

An electrode with a surface area of at least 110 cm² must be used for the
"Resection" programs and the "Moderate Coagulation" mode.

If an error message is generated, the display changes from green via yellow to red,
depending on the type of fault.
