Using the CUT or COAG 2 it will need to connect the handle and/or the foot-switch to the corresponding output CUT/COAG
2, in the MONOPOLAR 2 section.
The description of the supplying currents is in the next paragraphes, according to the predisposition order of the selection keys,
in the MONOPOLAR 1 and MONOPOLAR 2 section (see Fig. 1).

(CUT)
The better current for the cut is the sinusoidal pure without modulation, that is by 100%duty-cycle.
This current, suitable for cut without coagulation, can be moderately modulated to obtain cut with different level of
coagulation:
The modulation is an interval thanks to which it’s possible to distribute suitable “pulse trains” of
energy.
The level of modulation can be changed, between 100%, 80%, 60% e 40% values, choosing the
duty-cycle of supplied current, by + and
–
keys, the duty cycle value selected is shown by the
lightening of the corresponding warning light.
Naturally the level of coagulation increases when the duty-cycle value decreases
.

The ENAHNCED CUT current is a sinusoidal current characterized by modulation in amplitude and it is suitable to cut the

(BLEND)
The mixed current (BLEND) it is suited for coagulated cut when a deep coagulation together the cut is desired. This current is
made by sine current suited or the cut associated to low voltage current suited for coagulation (deep coag). With this, a
MIXING current suited for cut coagulated in absence of eschar and carbonization is obtained, particularly suitable for
endoscopic surgery.

(SPEEDY

The modulated current (SPEEDY 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.

OAGULATION
(DEEP
COAG)
The low voltage and low modulation current (DEEP COAG) it is suited for coagulation of deep layers of the fabric 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 Speedy coagulation.

OAGULATION
(SPRAY
COAG)
The high-tension
SPRAY COAG goes in the active electrode that isn’t in contact with the portion of tissue to treat and mostly
produces coagulation. This method is ideal to treat big surfaces with diffuse and surface blood loss (hepatic resection) and/or to
realize coagulation at level of the open sternum in heart surgery.

The equipment can be connect to, by the external output connector placed on the back panel (see
Back Panel
paragraph), an
Argon unit and supplies by handle or foot-switch the Spray Argon coagulation current.
Argon is an inert gas that is used to obtain a coagulative effect on the patient tissue. The gas in the bottle is supplied low
pressure in direction of the tissue, while a function with output tension is activated, suitable to prime the spark of argon and,
