Blue Laser ENT Surgery with the WOLF TruBlue 445 nm

What the WOLF TruBlue 445 nm laser is

WOLF TruBlue is A.R.C. Laser's blue laser platform for laryngology, otology and rhinology. It is a fibre-delivered diode laser with 10 W output power and a pulse length from 1 ms up to 45 s or continuous wave, so it offers continuous-wave, single-pulse and pulsed emission.

Because it is a diode, the unit is compact and portable. The manufacturer describes it as a system that can move between the operating room and office-based procedures, which is attractive for departments with limited theatre time.

Typical settings differ by task: continuous wave suits steady dissection, while pulsed modes limit thermal spread in delicate mucosa. Ask the supplier for guidance on power and pulse selection from the instructions for use, and make sure every surgeon completes the manufacturer's training before first use.

Why 445 nm: cutting and coagulation with one wavelength

The 445 nm wavelength lies at a peak of oxyhaemoglobin absorption. According to the manufacturer, that lets the laser combine precise cutting with simultaneous photothermal coagulation of small vessels, so the surgeon does not need to change instrument for haemostasis.

This is the main reason the blue light laser for ENT has attracted interest: a single fibre handles tissue division and bleeding control in a field where a few millimetres matter. How this wavelength compares with a green photoangiolytic laser is covered in our article on KTP versus blue laser in ENT.

Fibres, endoscopes and workflow

The laser is used with flexible, colour-coded HiFLEX fibres, passed through rigid and flexible endoscopes. Colour coding helps the nurse and surgeon confirm the right fibre quickly, which matters in a short office procedure.

Ask your supplier about the available fibre diameters, whether fibres are single-use or reusable, how they are prepared and tested, and what stock is held locally. These items drive the day-to-day cost and reliability of any fibre-delivered laser.

For an overview of which lasers fit which ENT tasks, see our ENT laser guide.

• Wavelength 445 nm, output power 10 W.
• Continuous-wave, single-pulse and pulsed modes.
• Pulse length 1 ms to 45 s, or CW.
• Colour-coded HiFLEX fibres for rigid and flexible endoscopes.

Office versus operating room

Office use depends on more than the laser: the room needs controlled access, signage, eyewear for the wavelength, a smoke plan and a patient-monitoring routine. The decision to treat a given patient awake or under anaesthesia is clinical and belongs to the surgeon.

For operating-room use, plan the fibre route, footswitch position and where the laser sits relative to the anaesthetic machine. If you also need a free-beam CO2 laser with a micromanipulator, the CO2 DUO3 Concept pairs the C-Las with a WOLF TruBlue 445 nm in a single tower. The newer WOLF TruBlue Pro adds PentaPulse modes and integrated smoke evacuation.

Whatever the setting, treat the beam as a Class 4 hazard. Fibre tips must be inspected before every case, the aiming beam confirmed, and the footswitch tested. A written checklist read aloud by the nurse before the first activation is a simple habit that prevents most avoidable incidents.

Selection checklist and next step

Compare any ENT laser on the same criteria: wavelength and power, available modes, fibre system, portability, smoke management, training, service and spare-parts availability in the UAE. Check how the device is registered and what local service the supplier provides.
