3 Scope
The use of electrosurgical equipment is predominantly in the following areas:
• General surgery
• Traumatology
• Cardiac and Thoracic Surgery
• Vascular Surgery
• Urology
• ENT
• Gynecology
3.1 Inteded Use
HF electrosurgical device HBS100; HF electrosurgical device HBS100 Vearex; HF electrosurgical
device HBS200 x-touch; HF electrosurgical device HBS 300 x-touch; HF electrosurgical
deviceHBS300argon x-touch; HF electrosurgical device HFiT®-T: An electrosurgical unit is a
generator that converts electronic energy into high frequency alternating current (RF) power. If this
current flow through biological tissue, heat is generated there, which is used to cut and coagulate the
tissue.
The device has monopolar and bipolar application modes.
In monopolar mode, RF current is applied to the tissue with an active electrode. The cutting or
coagulation effect is caused by a high concentration of current, i. a high current density over the small
area of the active electrode. As a result, an increase in temperature is generated and the water
evaporates from the tissue immediately surrounding the active electrode. Depending on the intensity
of the HF current, this leads to a standstill of bleeding or to a cut in the tissue. The HF current flows
from the active electrode to the neutral electrode and is distributed on its large surface area. Thus,
there reduces the density of the current and there are usually no unintended thermal effects at the
position of the neutral electrode. Through the neutral electrode, the current flows back to the
electrosurgery device.
In bipolar mode, the current path is limited only to tissue located between the two electrodes of a
bipolar instrument. The use of the neutral electrode is not required.
3.2 Contraindications
HF surgical devices should not be used with simulators such as bone stimulators. It also discourages
the use of electrosurgical devices when pacemakers, such as cardiac pacemakers, are in use.
