Why Can RF-grade High-frequency Electrosurgery Be Used Under An Endoscope? ​

Time:2023-08-13 16:39:08

The working principle of the RF-grade high-frequency electrosurgical knife is that the working end of the high-frequency endoscopic surgical electrode outputs high-frequency electromagnetic waves, which are concentrated in a small area. Under the action of this local high-frequency electromagnetic field, the water molecules oscillate rapidly and rub against each other, causing the intracellular water to evaporate, vaporize, dry the tissue, shrink and fall off, resulting in sterile necrosis, thereby achieving the purpose of ablation.


When the endoscope is working, the lens needs to be rinsed with saline to ensure the clarity of the endoscope. Physiological saline is a solution of sodium chloride, which contains sodium and chloride ions, and is a conductive solution. When the high-frequency endoscopic surgical electrode works under the endoscope, there are two poles at the working end of the electrode, forming a closed loop by itself, and no current flows through the human body.
