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.
DUOBLADE®
Low Temperature / Reduced Smoke / Clear Vision
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 cavities without blocking the line of sight.
Low operating temperature
Runs near 100 °C, shielding delicate tissue from excessive heat.
Minimal thermal injury
Focused energy confines thermal spread, preserving adjacent structures.
Exceptional hemostasis
Rapid vessel sealing minimizes bleeding, maintains a clear surgical field, and contributes to shorter procedure times.
Integrated smoke mitigation
Low-heat incision with distal suction reduces surgical smoke by up to 87% (up to 96% with evacuation), ensuring a clear surgical field and protecting staff safety.

¹ Pre-clinical testing demonstrated that Duoblade® operates at temperatures up to 100°C, lower than traditional electrosurgical devices, which exceed 230°C. Data on File.
² Pre-clinical histologic evaluation showed that Duoblade®resulted in up to 70% less thermal injury compared to traditional electrosurgical devices at the 50W cutting setting. Data on File.
³ Pre-clinical testing demonstrated that Duoblade® reduced blood loss by more than 93 % compared with a scalpel. Data on File.
⁴ Pre-clinical testing showed that Duoblade® reduced surgical-smoke production by up to 87 % versus traditional electrosurgical devices—and by up to 96 % when used with a smoke evacuator. Data on File.
