Liga Sealing Electro Surgical Unit Digital Power 400W ESU - 402DS

The Liga Sealing Electro Surgical Unit Digital Power 400W ESU-402DS is a microprocessor-controlled high-frequency surgical generator designed for cutting, monopolar coagulation, bipolar coagulation and Bi-Seal procedures. It is suitable for hospitals, operation theatres, surgical centres and departments performing major or minor surgical procedures.

This 400W electrosurgical unit provides Pure Cut, Blend-I, Blend-II, Contact Coagulation, Soft Coagulation, Spray Coagulation, Fulguration and Bipolar output modes. Independent digital displays and control sections for cutting, coagulation and bipolar/Bi-Seal functions allow the surgical team to view and adjust output settings conveniently.

The ESU-402DS uses quick-response microprocessor technology and dual isolated output circuits to support stable monopolar and bipolar performance. Its patient plate contact monitoring system provides audible and visual alerts if the neutral electrode connection is interrupted, helping improve operational safety during electrosurgical procedures.

The unit supports hand and foot activation and comes with a triple-paddle footswitch for cutting, coagulation and bipolar control. Its front-panel sockets are clearly identified to simplify accessory connection and reduce the possibility of incorrect setup.
