CO2 DUO3 Laser Concept: Two Wavelengths for ENT Surgery

Why combine CO2 and a fibre laser

A free-beam CO2 laser with a micromanipulator and a fibre-delivered laser solve different problems. The CO2 line-of-sight approach gives high-precision cutting under the microscope, while a flexible fibre reaches into the ear, larynx or lacrimal system and coagulates vessels.

The DUO3 Concept extends the C-Las CO2 laser with a tabletop system for a second laser, so the surgeon no longer has to choose between an articulated arm with micromanipulator and fibre delivery.

For departments that cover otology, laryngology and lacrimal work in one service, a single tower with two approaches can simplify instrument logistics, because one team learns one console and one set of accessories.

CORAL Blue and CORAL Green configurations

CORAL Blue adds the WOLF TruBlue 445 nm laser at 10 W; CORAL Green adds the Nuvolas 514 nm laser at 8 W. The CO2 laser provides 30 W, or 10 W in Super Pulse mode, at 10.6 µm. The complete system weighs 34.8 kg in the Blue version and 56 kg in the Green version.

Read about the blue wavelength in our article on the 445 nm blue laser for ENT, and the comparison with a green photoangiolytic laser in KTP versus blue laser.

• CO2 laser: 10.6 µm, 30 W / 10 W Super Pulse.
• CORAL Blue: WOLF TruBlue 445 nm, 10 W, 34.8 kg system.
• CORAL Green: Nuvolas 514 nm, 8 W, 56 kg system.
• C-Pro achromatic micromanipulator for the CO2 beam.

Switching during surgery and using each laser separately

The surgeon can switch during the procedure between the CO2 line-of-sight approach for high-precision cutting and the fibre-guided second laser for photoangiolytic coagulation of vessels. Flexible probes are available for middle-ear, laryngeal and DCR work.

Each laser can also be operated on its own and at different locations. A department can therefore run the CO2 laser in one theatre and the fibre laser in another, which helps utilisation. Consider how the two parts move, how they are connected and who is trained on each. For laryngeal setup, see laser laryngeal surgery.

Check how the two lasers are controlled: separate screens or a shared interface, how the footswitches are arranged and how the system indicates which laser is active, because clarity here supports safe switching in the middle of a case.

Comparing a dual wavelength ENT laser with separate devices

A dual wavelength ENT laser reduces the number of consoles and suits surgeons who regularly need both approaches. Separate devices offer flexibility to buy only what is needed first and to add later. Compare space, power requirements, training and the effect of one fault on the other laser.

Also compare against an integrated blue laser with smoke handling such as the TruBlue Pro if your work is mostly fibre-based. Our ENT laser guide gives a wider frame.

Ask the supplier for a written description of what happens if one laser needs service: whether the other can keep running and how quickly a replacement module can be provided.

Safety, service and next steps

The tower combines two Class 4 sources, so plan eyewear for both wavelengths, signage and smoke evacuation, and consult your anaesthetic team about airway fire prevention. Agree on local service, calibration and fibre stock before purchase.
