1.3 MONOPOLAR CUTTING

Monopolar cutting is the sectioning of the biological tissue caused by the passing of high density, high frequency current
concentrated by the tip of the active electrode. When the high frequency current, by the tip of the active electrode, is applied to the
tissue, it creates intense molecular heat in the cell so that the cell explodes. The cutting effect is achieved by moving the electrode
through the tissue and destroying the cell one after the other. The movement of the electrode prevents the propagation of the heat
laterally in the tissue, thus limiting the destruction to a single line of cells.
The best current for cutting is pure sine wave without any modulation which cuts very smoothly and provides the least thermal
effect with poor hemostasis 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.
DIATERMO 106 allows cutting with pure sine wave form as well as with two degrees of moderate modulation producing blend
wave form with different crest-factor, so more hemostatic effect than with pure sine wave form is achieved.
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
§
Keep the electrode clean
§
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

1.4 MONOPOLAR COAGULATION

Monopolar coagulation is the hemostasis of small blood vessel of the bodily tissue through the passing of high frequency current in
correspondence of the 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 from successive applications of current from penetrating
too deeply.
