TruBlue Pro Laser: PentaPulse and Integrated Smoke Evacuation

Built on the WOLF TruBlue platform

WOLF TruBlue Pro builds on the 445 nm WOLF TruBlue platform, a fibre-delivered blue diode laser for laryngology, otology and rhinology. The wavelength lies at a peak of oxyhaemoglobin absorption, which the manufacturer links to precise cutting with simultaneous coagulation of small vessels.

The Pro remains compact and portable. For the original model and ENT workflow, read our article on the blue laser for ENT; this page focuses on what the Pro adds.

PentaPulse: five emission modes

PentaPulse adds two emission modes to continuous wave, single pulse and pulsed. PeakPulse delivers 100 µs micropulses at up to 27 W peak power. PowerPulse delivers 5, 10 or 15 ms pulses at up to 17 W, designed for effective haemostasis, with repetition from 1 to 10 Hz.

More modes only help if they are easy to select and well documented. Ask for a live demonstration of each mode, how the settings are shown on the screen and how the manufacturer suggests selecting a mode for a given task. Selection of settings remains the surgeon's decision.

If your surgeons already use the TruBlue, ask how the PentaPulse modes affect training and department protocols, and allow time to rehearse the new modes in a safe setting.

• Wavelength 445 nm, CW power up to 10 W.
• PeakPulse: up to 27 W peak, 100 µs.
• PowerPulse: up to 17 W, 5, 10 or 15 ms, 1 to 10 Hz.
• Continuous-wave, single-pulse and pulsed modes retained.

FlowControl: CO2 cooling and smoke evacuation

FlowControl is exclusive to the Pro model. It combines CW power of up to 10 W with a CO2 flow that cools tissue, and an integrated smoke evacuation that keeps the surgical field clear. The gas can come from a central supply or a cylinder, and the unit remains compact and portable.

A blue laser with smoke evacuation built in addresses a practical problem in the narrow ENT field, where smoke obscures the view. It does not remove the need for a room-level plan; see our guide to laser plume evacuation for what else to consider. Check the gas source in your operating theatre and whether your office rooms have a cylinder option.

How to evaluate a blue laser with smoke evacuation

Ask how the integrated evacuation is filtered and how the filter or tubing is changed, how noisy the flow is, whether it works with the fibres and endoscopes you use, and what consumables are required. Compare against the alternative of a separate evacuator, considering space, workflow and cost.

If your department also wants a free-beam CO2 laser, look at the CO2 DUO3 Concept and the broader ENT laser guide. Compare with the standard TruBlue in our article on KTP and blue lasers.

Safety, service and next steps

Treat the 445 nm beam as a Class 4 hazard: controlled access, eyewear for the wavelength, and a fire plan, particularly when working near the airway. See airway fire prevention. Ask about local service, calibration and fibre availability in the UAE.
