Triangel, a leading manufacturer and the world’s No. 1 producer of Endolaser systems, is proud to announce the expanded application of its high-power 980nm + 1470nm dual-wavelength diode laser platform for ear, nose, and throat (ENT) surgery. This advanced laser system provides otolaryngologists with an unprecedented combination of cutting precision, hemostatic control, and tissue preservation, enabling safer and more effective minimally invasive procedures.
Optimized Wavelength Synergy for Soft Tissue Surgery
The system integrates two clinically validated wavelengths, each selected for its specific interaction with target tissues in ENT anatomy:
1470nm Laser – Highly absorbed by water, which is the primary component of mucosal and submucosal soft tissues. This wavelength enables precise, low-temperature ablation with a penetration depth of less than 1 mm, significantly reducing collateral thermal damage to delicate structures such as the vocal cords, tympanic membrane, and nerve endings.
980nm Laser – Strongly absorbed by hemoglobin and pigmented tissues, providing rapid hemostasis and coagulation. This wavelength is ideal for sealing small vessels and managing bleeding during procedures such as tonsillectomy, sinus surgery, and laryngeal lesion resection.
By combining both wavelengths, the Triangel ENT laser system allows surgeons to switch between or blend ablation and coagulation modes in real time, tailoring energy delivery to the specific surgical task.
Key Clinical Advantages for ENT Practice
Reduced Thermal Collateral Damage – The 1470nm wavelength’s water-specific absorption minimizes thermal spread beyond the target tissue, preserving adjacent structures and accelerating post-operative healing.
Superior Hemostasis – The 980nm component ensures effective coagulation of small to medium vessels (up to 1 mm), reducing intraoperative bleeding and improving visualization in endoscopic and microscopic fields.
Lower Post-Operative Pain and Scarring – Compared to traditional electrosurgery or CO₂ lasers, the dual-wavelength approach generates less charring and fibrosis, resulting in reduced post-operative pain, faster return to normal function, and better cosmetic and functional outcomes.
Versatile Fiber Delivery – The system is compatible with thin, flexible optical fibers ranging from 300 µm to 600 µm, allowing easy access through narrow anatomical passages, including the nasal cavity, sinuses, Eustachian tube, and larynx, under endoscopic or microscopic guidance.
Supported ENT Procedures
The Triangel dual-wavelength laser is suitable for a broad spectrum of otolaryngologic surgeries, including but not limited to:
Clinical studies have demonstrated the safety and efficacy of 1470nm laser in ENT applications. A prospective randomized trial comparing 1470nm diode laser with cold-steel tonsillectomy showed significantly less intraoperative bleeding, lower post-operative pain scores (measured by visual analog scale), and faster return to normal diet and activity in the laser group. Another study on laser-assisted uvulopalatoplasty for obstructive sleep apnea reported high patient satisfaction and minimal complications when using 1470nm wavelength with appropriate power settings.
For endonasal procedures, the combination of 980nm and 1470nm has been shown to achieve adequate volume reduction of hypertrophic turbinates with preservation of mucosal integrity, reducing the risk of empty nose syndrome.
Key Product Features
Dual-Wavelength Output – Independently controllable 980nm (up to 30 W) and 1470nm (up to 17 W), with pulse, continuous, and single-shot modes.
Real-Time Energy Monitoring – Built-in sensors display delivered energy (Joules) and tissue impedance, allowing precise dose control.
Fine Fiber Compatibility – Accepts bare fibers or radial-tip fibers as small as 300 µm, facilitating atraumatic passage through working channels of rigid or flexible endoscopes.
Safety Features – Automatic shut-off on fiber disconnection, contact detection, and user-settable maximum energy limits.
User-Friendly Interface – Preset programs for common ENT procedures with customizable parameter storage for individual surgeon preferences.
Triangel remains committed to advancing minimally invasive laser technology for surgical specialties. The 980nm + 1470nm dual-wavelength system is a direct response to the growing demand for precision, safety, and efficiency in modern ENT practice.
