Criteria Of A Good Cutting Technique; Coagulating; Coagulating Technique - Cooper Surgical LEEP PRECISION LP-10-120 Manual De Funcionamiento

8.3.1 Cutting
Blend: Cutting is done not by the electrode, but by the high frequency energy concentrated at the
electrode's tip . This high frequency energy generates molecular heat in each cell to the point at
which the fluids in the cell vaporize and the cell explodes. By applying this energy to individual cells
in sequence, that is, by moving the electrode continuously through the tissue, the line of destruction
is limited and the cutting effect is realized . At the same time, the capillaries are sealed, resulting in
almost bloodless cutting, hence the term "blended cut ."
Pure cut: This is almost like using a cold scalpel with very little or no hemostasis .

8.4 Criteria of a Good Cutting Technique

There are three criteria of a good cutting technique:
1. The electrode should "float" through the tissue without dragging or resistance.
2 . There should be only very slight, if any, change in the tissue color due to dehydration or charring .
3 . No tissue shreds should adhere to the electrode .

8.5 Coagulating

The LEEP PRECISION Generator is designed for high fulguration so tissue bleeders can be sealed
without burning the uninvolved tissue . Coagulation takes place when the high frequency current is applied to
the tissue with a current density sufficiently concentrated to dehydrate the cells and coagulate their organic
contents, but without penetrating deeply into the tissue .
This procedure is almost self-limiting because the surface coagulation first created protects the underlying
tissue against excessive depth of coagulation .
Coagulation appears as a white spot on the surface of the tissue, emanating from the point of contact to the
Ball Electrode . The depth of coagulation is approximately equal to the lateral spread of coagulation .
In contrast to cutting, when coagulating, the Ball Electrode should make contact with the tissue before the
physician depresses the Foot Switch or Hand Switch .
Start with a LOW power setting (15), changing the mode button to COAG .
Make light contact with the surface of the tissue with the Ball Electrode . Depress the Foot Switch or Hand
Switch to activate the current, coagulating the area for several seconds, then release the Foot Switch or
Hand Switch and remove the electrode from the tissue .
Note the appearance of the tissue, which should appear blanched . Turn the power intensity up step by
step, repeating the procedure . Observe the characteristics of the coagulated tissue with each setting . The
degree of coagulation obtained at a particular setting will vary with different tissue and different conditions .
Determine which setting is best for various procedures . When treating any condition, if proper coagulation is
not apparent after one application, immediately increase the intensity setting as long as the Patient Return
Electrode is properly in place .
Never repeatedly apply the current to the same area; this may create heat and seriously
damage underlying tissues .

8.6 Coagulating Technique

The Ball Electrode can control hemorrhage . When applied for a second or two, electronic coagulation current
will coagulate small capillaries easily . Larger vessels can be picked up
with hemostats, which in turn may be touched by the Ball Electrode using electronically generated current .
This will seal all vessels that are held in the tips of the forceps .
Always make contact with the tissue before depressing the Foot Switch or Hand Switch
when using the coagulation current .
