Electrosurgical Instruments
Electrosurgery is the cutting and coagulation using high-frequency,
alternating currents. It includes
- Electrobisection: Cutting with RF-currents (HF-currents).
"Cold" cutting is electrobisection with smooth,
non-modulated RF-current where as "Hot" cutting is
electrobisection with a modulated RF-current such as blended or
mixed currents.
- Electrohemostatis: Sealing of small vessels and
capillaries with RF-currents, using forceps, ball, blade and other
large surface electrodes. It is also used for tissue destruction.
- "Cold" coaguluation: Electrocoagulation with a
smooth, non-modulated RF-current, employing coagulation electrodes
such as clamps, balls, etc.
- "Hot" coagulation: Electrocoagulation with
modulated RF-currents such as spark-gap, TESLAR, etc., employing all
kinds of electrodes, including cutting electrodes.

What are electrosurgical instruments?
Electrosurgical instruments are widely used most of the modern health care
unita and hospitals. They are available in a variety of shapes and
configurations and their main purpose is to cut tissues by means of
high-voltage, high-frequency electrical energy. Most of the electrosurgical
instruments are connected by electrical cords to electrosurgical generators.
