4.3 OPERATION MODE

WITCHING
O
N
When switched on the electrosurgical unit performs automatically a test to establish the correct operation
of itself and of the connected accessories as well. In case anomaly is found an alphanumeric message it is
shown coded according to the chart codes brought in the chapter MAINTENANCE. This test lasts about
10 seconds. At the end of the control the equipment restores last use operational conditions.

IRCUIT
The neutral electrode is continually watched by a special circuit that prevents, danger of burns to the
patient due the loss of contact between the reference plate and the patient skin, if split electrode is used.
The circuit also watched the connection of the plate to the unit.
If the impedance value of the patient circuit is less than 200 ohm the value is not accepted.
4.4 PRESELECTION OF THE DELIVERABLE CURRENT
The deliverable current for the surgical operations can have preselected through push button for:
MB122 – MB160
MB132
4.4.1
C
UT
C
URRENT
(CUT)
The best current for the cut is the pure sinusoidal wave without modulation that means with duty-cycle
100%. Such current, proper for cut without coagulation.
4.4.2
C
OAGULATED
-C
UT
C
URRENT
(BLEND)
The coagulated-cut current (BLEND) it is suited for coagulated cut when a deep coagulation together
the cut is desired. This current is made by sine current e suited for the cut associated to low voltage
current suited for coagulation (soft coag). With this blending, a current suited for cut coagulated in
absence of eschar and carbonization is obtained, particularly suitable for endoscopic surgery.
4.4.3

UPERFICIAL
C
OAGULATION
C
URRENT
(FORCED
COAG)
The modulated current (FORCED COAG) it is characterized by good property of surface coagulation
behaving at the time it probable production of eschar and partial carbonization of the tissue. The
advantage of this type of coagulation resides in the rapidity with which the effect is gotten.
4.4.4

EEP
C
OAGULATION
C
URRENT
(SOFT
COAG)
The low voltage and low modulation current (SOFT COAG) it is suited for coagulation of deep layers
of the tissue in which the coagulation of the cellular albumin is gotten in absence
of carbonization and without production of eschar. The process of coagulation is
in this case more time expensive than that of the forced coagulation.
4.4.5
B
IPOLAR
C
OAGULATING
C
URRENT
(BIPOLAR)
This current is low voltage pure sine current suited for coagulation without
carbonization either monopolar or bipolar. The use of bipolar forceps it is allowed
only with this current. To allow the connection of the cable for bipolar forceps it
is necessary the use of an optional adapter (
REF
00498.04) that prevents any
other type of current from delivering.
Particularly interesting it is the automatic termination of the bipolar coagulation
through the presetting of the time of current delivery (only for MB132 model).
