Ecut 400S

Ecut 400S

electrosurgical unit

Ecut 400S is a versatile electrosurgical unit for surgical procedures through all types of tissue. It has an integrated seven power output and a tissue responding and automatic solid or split return electrode recognition function. With this function surgeons can perform highly precise and safe operations.

ECUT 400S electrosurgical generator system perform in mono & bipolar working modes but with different power range.

The 7 integrated different monopolar and bipolar modes, tissue responding and automatic return electrode monitoring to give intuitive indication of potential burn risk, which enables highly efficient and safe surgical cutting and coagulation through all surgical procedures.

Compact Design

The ECUT 400S benefiting from an structural design and light weight make it mountable  on support tray of ceiling pendant for endoscopic application.

Control and measurement

Front panel of ECUT 400S consists of two differently sloped areas, 130 ° sloped “Measurement area” and 160 ° sloped “Control area”, to provide operator great physical comfort when they setup or adjust power setting and observe the power measurement and neutral electrode’s contact situation from an ergonomic viewing angle and height.

Smoke evacuation (optional)

Heat-producing surgical methods (like electrosurgery or laser) mostly bring surgical smoke that contain hazardous (like acrylonitrile and hydrogen cyanide) which may blur surgical vision (especially for procedures into cavity) and cause harm to respiratory systems of patients, surgeons or operating theatre staff.


Resistance from nerve, muscle, adipose tissue and bone to electrical circuits vary. Impedance response technology in ECUT 400S electrosurgical system measures the tissue resistance then automatically adjust power output under pre-set range, to optimize real cutting or coagulation performance, which makes ECUT 400S   system qualified for wide range of applications, from various open surgeries to minimal-access procedures, as well as under-water operation in Gynaecology and Urology.
