Monopolar Coagulation - Gima DIATERMO 108 Manual De Instrucciones

GIMA SpA
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 electrosurgery 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 judgement 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
adviced);
•
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 colour;
•
no fibres of tissue remained onto the electrode.

1.5 MONOPOLAR COAGULATION

Monopolar coagulation is the haemostasis of small blood vessel of the bodily tissue through passing
of high frequency current in correspondence of active electrode. When the current density is reduced
and a broad-surfaced electrode is used, to dissipate the energy over a larger area, the effect is to dry
out the surface cells, without deep penetration, resulting in coagulation. These coagulate surface
cells then serve as a layer of insulation, preventing heat derived by successive applications of
current from penetrating too deeply.
The current normally used for coagulation is modulated and depending from the modulation
percentage is the smoothness of cutting, goodness of haemostasis and likelihood of tissue
destruction. Deeper current modulation brings to somewhat roughly cutting and the chance of some
slight depth of tissue destruction but more efficient coagulation.
The following rules help the operator to obtain good coagulation: however every user must follow
first of all his professional judgement as he does every time in his practice.
•
Select a ball or heavy wire electrode;
•
locate the bleeder, after have wiped the excess blood from the area, contact lightly the bleeder
before activating the electrode;
•
stop the electrode activation as soon as the tissue blanches to avoid tissue damage;
•
maintain clean the electrode's tip (the optional sponges F7520 to clean the electrodes are
adviced).
