New ESG-150 Electrosurgical Generator

Simply Intelligent

Olympus’ ESG-150 is the latest generation of our standard electrosurgical generator designed to achieve successful results in standard GI and Pulmonary endoscopic procedures with constant voltage regulation technology that modulates power to automatically deliver the lowest effective adjusted power output in monopolar and bipolar applications. This intuitive system supports a broad portfolio of Olympus endoscopic devices used in electrosurgery to treat GI and Pulmonary disorders.

The ESG-150 electrosurgical generator is designed to be used for the following electrosurgical applications:

  • Bipolar electrosurgical cutting and coagulation
  • Monopolar electrosurgical cutting and coagulation, which requires a neutral electrode

The ESG-150 is equipped with several cutting and coagulation modes which are primarily designed for procedures in the gastrointestinal and respiratory tract. All device settings are completed via the touch screen located on the front panel and activation is enabled with the compatible double pedal footswitch.

Key Benefits

Designed with you and your patients in mind, the ESG-150’s intuitive design avoids complexity of use and setup, providing user optimization and overall procedural efficiency.

Key benefits of the ESG-150 include the following:

  • Perform endoscopic procedures with ease using basic or advanced modes & settings
  • The large, easy to read graphical interface provides increased setting visibility.
  • An intuitive touch screen provides ease of use to set up physician specific settings along with making adjustments when required for a more effective procedure.
  • The storage functionality for settings enables time efficiency for the user, increases reproducible results as well as safety by increasing the level of standardization.
  • Several effect settings per mode allow for customization and precision to target appropriate tissue effect.
  • Standardized instrument sockets provide flexibility to accommodate most devices on the market that require energy.
  • Precise and easy to read error messages simplify error handling along with renowned and proven safety features: Fast Spark Monitor, High Power Cut Support, and Contact Quality Monitor.
Olympus ESG foot switch
  • A foot switch with added automatic foot switch assignment to the generator simplifies the set up.
neutral electrodes
  • The Olympus Energy portfolio also includes a wide offering of neutral electrodes including a variety of sizes and designs, skin-friendly surface, split-design with hydrogel, minimizing the risk of pad site burns and providing optimum skin contact.
