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.
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.
