The Hospital Electrosurgery Unit MB 400D, GIMA brand, represents an advanced solution for modern surgery, designed to ensure high performance and safety for both the patient and the surgeon. Thanks to its high-frequency technology, this device allows for simultaneous monopolar and bipolar surgery, making it ideal for a wide range of surgical procedures.

Dual Operational Activity

• Two output channels for monopolar cutting, allowing for efficient operation.


• Two calibrations and independent channels for the most frequent monopolar coagulations, ensuring precision and control.

Controlled Cutting Procedures

• Intensified cutting currents for incision without eschar, minimizing damage to surrounding tissues.


• Cutting current with coagulating properties for dissection with controlled bleeding, improving visibility during surgery.


• Low capacitive coupling in endoscopic procedures using Slow BLEND current, optimizing safety and effectiveness.

Dual Controlled Coagulation Procedures

• SPEEDY coagulation and DEEP coagulation available for two operators, increasing flexibility during operations.


• SPRAY coagulation obtainable with a handpiece or pedal, for precise control during procedures.

Advanced Features for Bipolar Surgery

• Bipolar cutting with selectable bleeding control, for optimal hemorrhage management.


• Slow BLEND cutting currents for delicate and controlled operation.


• Automatic start and stop of coagulation, activatable separately, for greater convenience during surgery.

Total Safety for Patient and Surgeon

• Electronic Skin Plate Electronic Control (SPEC) to continuously verify the contact impedance between the patient's body and the neutral plate.


• Continuous monitoring of radiofrequency leakage current to ensure maximum safety.


• Automatic compensation for mains voltage variation before starting power and radiofrequency delivery.

Customized Procedures

• Independent choice of coagulation currents and power levels for each of the two operators, for tailor-made operation.


• Ten configurable personal procedures that can be recalled immediately, for greater efficiency during operations.

Extension and Connection Signal Conduction

• Outputs for controlled connections of argon plasma units and smoke extractors, for simple integration with other surgical devices.

Automatic Self-Diagnosis

• Automatic diagnostic check of the electronic unit's functionality and connected accessories, with coded indication of malfunctions found.
