Duoblade® utilizes Dielectric Ultra-focused Oscillation(DUO) technology, a combination of a uniquely shaped cutting-edge blade fully insulated with a heat-resistant oxide layer and non-stick coating.
This localizes a uniform electric field around the edge of the blade with a concentration at the distal tip, enabling exceptional low temperature soft tissue dissection blended with simultaneous optimized hemostasis around the blade perimeter.
OUR SOLUTION
Low Heat · Low Smoke · High Clarity
All the innovation in one blade
Powered by CRESEN’s proprietary DUO (Dielectric Ultra-focused Oscillatory) heating technology, Duoblade delivers precise cutting, reliable coagulation and active smoke evacuation through a single, disposable instrument. A telescoping, 360 °-rotating shaft and slim housing give surgeons reach inside deep or narrow corridors without blocking the line of sight.

Low operating temperature
Runs below 100 °C, shielding delicate tissue from excessive heat.

Minimal thermal injury
Focused energy confines thermal spread, preserving adjacent structures.

Exceptional hemostasis
Rapid vessel sealing keeps the field dry and helps shorten procedure time.

Integrated smoke mitigation
Low-heat incision plus distal suction removes > 30 % more smoke than competitive blades, preserving visualization and staff safety.
