Revision 1
Forced Prep
In comparison to the Forced Clamp current, the forced coagulation current Forced Prep effects coagulation
more quickly. This makes this current suitable for preparation, since despite its dominant coagulation it has
an effective cutting power. If the instrument or electrode is only slightly in contact with the tissue, by
design sparking between the tissue and the electrode will be observed. Thus the tissue at the point of
contact will be strongly desiccated; slight tissue carbonization will take place. Due to quickly occurring
coagulation, the effective depth is limited. Using the effect setting, the voltage can be changed and thus the
hemostatic effect slightly varied.
Basically, under the condition that the same amount of HF energy is required the following apply:
•
Low penetration:
Short application time and correspondingly high HF output power
•
Deep penetration:
Long application time and correspondingly low HF output power
Activation is done via the blue switches (finger or foot).
Danger of injury by operating errors!
In case of indirect application via a hand-held instrument, this should be insulated so as not to expose the
surgeon to the HF voltage transmitted directly from the active electrode to the instrument. It must be
kept in mind that the surgical glove is no defined electrical insulation for this current, and arcing is indeed
likely.
Active accessories to be used with this current must be able to withstand an HF voltage of at least 2,000 V
(depending on the selected effect).
