The Olympus ESG 400 represents the latest generation of universal HF (high-frequency) generators, created to provide surgeons with superior cutting efficiency, dependable performance, and simplified operation. Designed with a heavy-duty power system, the ESG 400 ensures fast plasma ignition and stable cutting quality even in difficult or variable tissue conditions.

Equipped with a large bipolar “loop” electrode, it delivers unmatched resection capability for procedures such as TURis, TCRis, trans-urethral surgery, trans-cervical resection, resection in saline, and laparoscopic applications.

Its advanced “fast spark monitor” analyzes tissue response 4,000 times per second, maintaining consistent cutting performance and improving patient safety.

When paired with the USG-400, the ESG-400 powers THUNDERBEAT technology a combination of ultrasonic dissection speed and advanced bipolar vessel sealing up to 7 mm supporting a wide range of surgical disciplines.

Despite its high-level performance, the ESG-400 remains easy to use thanks to its clear touchscreen, intuitive layout, and compatibility with ENDOALPHA integrated OR systems. It is ideal for general surgery, GI procedures, gynecology, urology, endourology, and bipolar resection cases.
