URRENT
(BIPOLAR
BLEND)
The mixed current BIPOLAR BLEND, supplied by the bipolar forceps is adapted to the cut and to the coagulated cut when a
deep coagulation together the cut is desired. this current is made by sinusoidal current adapted to the cut associated to current
for low-tension coagulation (deep coag).

URRENT
(BIPOLAR
COAG)
Type of coagulation practicable with bipolar forceps and that allows to supply, by handle or foot-switch, the RF output power
on a impedance value of 100 ohm. This value is normally on the section of tissue between the forceps. This modality is
practicable by SELECT key (see
Autostart and Autostop
paragraph).
7.5.3.1
A
UTOSTART AND
A
UTOSTOP
In the ‘BIPOLAR COAG’ section there is the SELECT key, by this to enter to different four settings for the bipolar
coagulation:
1) No automatism for the delivery (at the first use of the device). The delivery is realized by pressing the foot-switch and stops
by leaving again the foot-switch;
2) START. The selection of this function is realized at a first pressure of the SELECT key and it’s indicated by the lightening
of the corresponding warning light. The delivery is started, by pressing the foot-switch, if there is contact between active
electrode and tissue, and it stops by leaving again the foot-switch;
3) STOP. The selection of this function is realized at a second pressure of the SELECT key and it’s indicated by the lightening
of the corresponding warning light. The delivery is started, by pressing the foot-switch, (if also there isn’t a contact between
tissue and active electrode) and stops itself for the impedance value higher than 200 Ohm.. So by pressing the foot-switch, if
there is an impedance value higher than 200 Ohm, the delivery doesn’t start.
4) AUTOSTART/AUTOSTOP. By this setting, practicable by three pressures of the SELECT key indicated by the lightening
of the START and STOP warning lights, the bipolar coagulation can automatically be activated and disarmed.
The destribution starts, by pressing the foot-switch, if there is a contact between tissue and active electrode and stops for the
impedance values higher than 200 Ohm.
So by pressing the foot-switch, if there is an impedance value higher than200 Ohm, the delivery doesn’t start.
Another pressure of the SELECT key brings again to the no automatism function (1).
The delivery is always stopped by leaving again the foot-switch.
The Delay Clamp function can’t be useful if the automatism for bipolar coagulation has been chosen. This function can be
selected from the Program section (see
Program
paragraph) and allows to set a delay for delivery respect to the contact bipolar
forceps-tissue.

Bipolar forceps and double foot-switch:
Connect the bipolar forceps to the ‘BIPOLAR’ connector. The equipment isready to
supply the only functions BIPOLAR (BIPOLAR CUT, BIPOLAR CUT/COAG 80%, BIPOLAR CUT/COAG 60%, BIPOLAR
CUT/COAG 40%, BIPOLAR BLEND e BIPOLAR COAG). Supply the BIPOLAR CUT or BIPOLAR BLEND current by
pressing the foot-switch associated to the cut (yellow) or supply the BIPOLAR COAG current by pressing the foot-switch
associated to the coagulation (blue). To not damage the forceps don’t short-circuit the points.
