Frequently Asked Questions
What is Duoblade, and how is it different from conventional electrosurgical blades?
Duoblade is a next-generation electrosurgical blade that combines dual insulation and dielectric heating. Unlike conventional blades that rely on high-temperature Joule heating (>250 °C), Duoblade operates at approximately 100 °C, minimizing tissue damage and surgical smoke.
How does Duoblade enable cutting and coagulation at low temperatures?
Duoblade uses Dielectric Ultra-focused Oscillatory (DUO) heating, which directly excites water molecules inside tissue. This method creates focused electric fields that heat the tissue internally, and the natural boiling point of water (~100 °C) acts as a self-limiting mechanism.
Is low-temperature energy sufficient for effective cutting and coagulation?
Yes. Duoblade delivers sufficient thermal energy to vaporize intracellular water, causing controlled tissue rupture (cutting) and coagulation. This dielectric heating ensures precise performance while minimizing collateral damage.
Why can’t conventional blades operate at low temperatures like Duoblade?
Traditional blades use Joule heating, which relies on direct electrical contact and resistive heating. While simple, this generates excessive heat, increasing thermal injury and smoke. Coating the lateral surface to limit temperature often compromises hemostatic performance – unlike Duoblade, which delivers both low temperature and reliable coagulation.
How does Duoblade maintain strong hemostasis at lower temperatures?
Duoblade’s electrode is precisely engineered to concentrate electric fields at the edge for cutting and distribute them across the surface for coagulation. This dual-zone design enables reliable hemostasis, as demonstrated in pre-clinical studies.
Is Duoblade patented?
Yes. Duoblade’s core technologies, including the dual-insulation architecture and dielectric heating mechanism, are patented and certified as a New Excellent Technology (NET) by the Korean government.
Does Duoblade require a specialized electrosurgical unit (ESU)?
No. Duoblade is fully compatible with standard RF-based electrosurgical generators. No additional hardware or system modifications are needed.
What are the clinical benefits of using Duoblade?
- Minimal tissue necrosis
- Strong and stable hemostasis
- Reduced risk to implantable devices
- Less surgical smoke with integrated evacuation channel
- Enhanced surgical control via telescoping and rotating shaft
- Plug-and-play compatibility with existing systems
