ES120 OPERATION MANUAL
IU ES120 2009-03-01 ENG.3.0
1. Purpose of the ES120 system
The electrosurgical system ES120 is all-purpose diathermy based on high-frequency current
flow. ES120 is designed for use in electrosurgical treatment:
•
pure cutting ,
•
blend cutting with hemostasis ,
•
soft coagulation,
•
forced coagulation,
•
bipolar coagulation.
2. Electrosurgery basics
Currently electrosurgery is used in all kinds of surgical procedures. In order to use
electrosurgery effectively, it is necessary to learn, understand and apply safety rules designed
to protect both the surgeon and the patient.
Surgical diathermy unit uses electricity to generate high - frequency (HF) alternating current.
The thermal effect caused by the HF current flowing through the tissue is used for tissue
cutting or coagulation. Surgical diathermy unit generates alternating current of frequency
higher than 300 kHz. Due to that there is no risk of unintended electrolysis effect or muscle
and nerve stimulation.
When working with a surgical diathermy unit always remember the
two fundamental rules:
•
Current flows along all the available paths.
•
HF leakage current flows between two adjacent conductors
even if they are separated from each other.
