A Surgical Blade That Cuts Without the Heat
Duoblade is a surgical instrument that operates near 100°C instead of 230°C, cutting tissue while reducing smoke and blood loss in the operating room.

The Hidden Cost of a Standard Surgical Tool
Traditional
electrosurgical devices have always done their job by running hot, often
exceeding 230°C, hot enough to cut and seal tissue in one motion, but also hot
enough to damage the healthy tissue surrounding the incision and fill the
operating room with smoke. Surgeons and staff have simply accepted that
trade-off for decades. Cresen built Duoblade specifically to challenge it.
Duoblade is the first step in a journey that brings precision, safety, and
accessible innovation to every operating room, built around the principle that
breakthroughs belong in daily care, not locked behind high costs.
So,
what makes this blade fundamentally different? Duoblade utilizes Dielectric
Ultra-focused Oscillation, or DUO, technology, a combination of a uniquely
shaped cutting-edge blade fully insulated with a heat-resistant oxide layer and a non-stick coating. Therefore, instead of relying on raw heat spreading across
the blade, the design localizes a uniform electric field around the edge of the
blade with concentration at the distal tip, enabling exceptionally
low-temperature soft tissue dissection while still achieving the bleeding
control surgeons depend on.
How a Cooler Blade Still Cuts and Seals Effectively
A
low-temperature surgical blade is only useful if it doesn't sacrifice
performance for safety, and this is exactly the balance Duoblade's data is
built around. The device runs near 100°C, shielding delicate tissue from
excessive heat compared to traditional tools. That lower temperature isn't just
gentler; 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, meaning focused energy confines thermal spread and
preserves the structures next to the incision rather than damaging them.
Lower
heat doesn't come at the cost of bleeding control either. Rapid vessel sealing
minimizes bleeding, maintains a clear surgical field, and contributes to
shorter procedure times, with pre-clinical testing demonstrating that Duoblade
reduced blood loss by more than 93% compared with a scalpel. In addition, the
design tackles a problem surgical teams deal with on every single procedure:
smoke. Low-heat incision paired with distal suction reduces surgical smoke by
up to 87%, rising to up to 96% when used with a smoke evacuator, keeping the
surgical field visibly clear and directly protecting the breathing air of
everyone in the room.
How the Instrument Adapts to Different Procedures
Beyond
the core cutting technology, Duoblade was engineered around real, practical
demands inside an operating room, not just lab performance numbers. A
telescoping, 360-degree rotating shaft and slim housing give surgeons reach
inside deep or narrow cavities without blocking their line of sight, with the
shaft sliding to extend reach from 5 to 12 centimeters without needing to swap
instruments mid-procedure. The handpiece itself spins freely across the full
360 degrees, reducing wrist strain and improving control over the line of cut
during long procedures.
That
flexibility extends across an entire product lineup rather than a single fixed
device. The DB1SEP model combines integrated suction, shaft rotation, and
telescoping into a full-feature instrument built for deep-cavity work, while
the DB1SP focuses on precise dissection without suction, the DB1EP offers
cost-effective smoke control for open procedures, and the DB1P delivers the
core DUO technology in its simplest form. Every model also offers a distal tip
option exposing just 3mm of the blade, which may prevent thermal injury at
alternate sites. With every model FDA-cleared and connecting to any IEC
60601-compliant monopolar generator between 30 and 80 watts, Duoblade is built
to integrate into operating rooms that already have the equipment surgeons rely
on, rather than requiring an entirely new setup.
