Monopolar
Cut
Monopolar
cut
is
the
sectioning
of
the
biological
tissue
achieved
by
the
high
‐
density
passage
of
HF
current,
which
is
concentrated
at
point
of
the
active
electrode.
The
HF
current,
when
it
is
applied
to
the
tissue,
through
the
point
of
the
active
electrode,
it
creates
intense
molecular
heat
in
the
cells
so
high
that
explosion
of
it
is
caused.
The
cut
effect
is
achieved
by
moving
the
electrode
through
the
tissue
and
destroying
the
cells
one
after
the
other.
The
movement
of
the
electrode
prevents
the
propagation
of
the
side
heat
in
the
tissue,
thus
limiting
to
a
single
line
the
cells’
destruction.
The
best
HF
current
for
cutting
is
pure
sine
wave
without
any
modulation
that
cuts
very
smoothly
and
provides
the
least
thermal
effect
with
poor
haemostasis
while
cutting.
Because
its
effects
can
be
precisely
controlled,
it
can
be
used
safely
without
damage
to
the
bone,
but
since
good
coagulation
while
cutting
is
one
of
principal
benefits
of
using
electro
surgery
a
current
with
a
certain
amount
of
modulation
is
desirable.
The
following
rules
help
the
operator
to
obtain
good
cutting,
however
every
user
must
follow
first
of
all
his
professional
judgment
as
he
does
every
time
in
his
practice.
Keep
the
tissues
moist
but
not
wet;
Survey
the
stroke
before
activate
the
electrode;
Keep
the
electrode
perpendicular
to
the
tissue;
Activate
the
electrode
before
making
contact
with
the
tissue;
Maintain
clean
the
electrode’s
tip
(the
optional
sponges
F7520
to
clean
the
electrodes
are
advised);
Wait
at
least
five
seconds
before
to
repeat
a
stroke.
When
the
output
power
is
properly
set
there
should
be:
no
resistance
to
the
electrode
movement
through
the
tissue;
no
change
in
the
cut
surfaces
color;
no
fibers
of
tissue
remained
onto
the
electrode.
Monopolar
Coagulation
Monopolar
coagulation
is
the
haemostasis
of
small
blood
vessel
of
the
bodily
tissue
through
passing
of
high
frequency
current
in
correspondence
