maxium® smart C Electrosurgery Unit with maxium® smart Beam

Revision 1
•
If an activation sound is audible although no current has been intentionally activated, then there is a
system malfunction. The
ON/OFF
key allows turning off the unit so that it cannot emit any energy.
The activation sound always accompanying activation of an HF current is an important safety element.
Therefore it can be turned down, but not off. Taping over of the sound outlet or other measures to
“muzzle” the unit constitute illegal manipulation of a safety device!
•
In endo-surgical application, the automatic activation system of the bipolar coagulation currents must
not be switched on, since otherwise unwanted activation by accidental tissue contact or by unintended
contact with the metallic trocar sleeve during placement of the electrosurgical instrument might occur.
For this reason, in the case of the selection of a program comprising a bipolar current with automatic
activation, attention is drawn to this fact. The user must then decide whether he or she wants to have
the automatic activation in the program, otherwise it will automatically be shut off.
5.8.2
Combination with other devices
When combining the maxium® smart C with electro-medical devices other than those specified in this
manual or linking it to an integrated electromedical system, attention must be paid to the following points:
•
Accessories to be connected to the analog and digital interfaces of the unit must demonstrably satisfy
the applicable IEC specifications (e.g. IEC Standard 60950 for data processing units and IEC 60601-1 for
electromedical equipment).
•
Anyone who connects additional units to the input or output section thereby configures the system
and is thus responsible for compliance with section 16 of IEC 60601-1.
•
In case of questions, the Martin Service Center provides information, see section 2.2 “Hotline”,
page 10.
5.8.3
HF output power
The hazard potential of electrosurgery increases with the power applied. Therefore the following rules are
to be observed:
•
The HF output power should be selected as low as possible for the application in question, and not
higher than necessary for the application in question. On the other hand, it should also be kept in mind
that too lower power settings may also pose a risk, e.g. if due to insufficient power cutting is not
achieved and local coagulation results where it is not desirable or even dangerous.
•
Insufficient effect in case of normal settings may have the following causes, which are to be checked
before increasing HF output power:
–
Poor contact of the neutral electrode with the patient’s body
–
Poor contact in plug-in connections
–
Wires broken beneath the insulation
–
Encrusted electrodes
•
A defect in the electrosurgery unit may cause undesirable increases in the HF output power.
