1470nm/980nm Endovenous Laser Disured (EVLT) Μηχανή απομάκρυνσης των φλεβών κιρσών

Endovenous Laser Treatment (EVLT) utilizes the thermal effect of laser energy and its interaction with biological tissue to treat varicose veins. This device emits laser energy through a fiber-coupled source and delivers it precisely to the inner vascular wall via a specialized radial (ring) fiber. The result is effective closure and fibrosis of the affected vein, ultimately treating lower limb varicosities.

The laser wavelength used in this system is highly absorbed by melanin and deoxygenated hemoglobin, enabling simultaneous vaporization, coagulation, and hemostasis during the procedure.

How Endovenous Laser Treatment (EVLT) Works

EVLT is a minimally invasive laser procedure used to treat varicose veins by closing off faulty or enlarged veins from the inside using targeted thermal energy.

🔬 Step-by-Step Working Principle:

1. Vein Mapping & Παρασκευή
   The affected vein is located using ultrasound imaging. The treatment area is cleaned and numbed with local anesthesia.

2. Fiber Insertion
   A small puncture is made, and a thin optical fiber (usually radial type) is inserted into the diseased vein. The fiber is guided along the length of the vein under ultrasound supervision.

3. Laser Activation
   The laser is activated to emit energy at a specific wavelength (typically 1470nm, ή combined with 980nm), which is strongly absorbed by water and hemoglobin in the vein wall.

4. Thermal Ablation
   As the fiber is slowly pulled back, the laser energy heats and damages the vein wall, causing it to collapse, seal shut, and initiate a fibrosis process.

5. Vein Absorption
   The closed vein is gradually reabsorbed by the body, and blood is naturally rerouted to nearby healthy veins.

✅ Why EVLT Is Effective

• Precise & Targeted: Minimizes damage to surrounding tissue

• Ελάχιστα επεμβατική: No large incisions, quick recovery

• Dual Wavelength Option: 1470nm (water) + 980nm (hemoglobin) absorption

• Rapid Healing: Less bruising, less pain, and quick return to normal activities

• Αποδεδειγμένα αποτελέσματα: High vein closure rate and low recurrence

Advantages of 980nm Diode Laser

• High absorption by hemoglobin: Ensures effective targeting of blood vessels.

• Skin regeneration and collagen stimulation: Enhances skin texture and elasticity.

• Improves microcirculation: Increases capillary permeability, activates healthier cells and tissues.

• ATP production boost: Helps reduce pain, inflammation, and swelling, while accelerating tissue repair and wound healing.

⚠* Σημείωμα: The radial (ring) fiber is a consumable item designed for interventional procedures. It should not be reused. It cannot be cut and must either be sterilized before single use or disposed of after one use.

Advantages of 1470nm Diode Laser

The 1470nm wavelength is a new-generation semiconductor laser with unique clinical benefits:

• Dual absorption mechanism: Energy is absorbed both by hemoglobin and intracellular water.
• High cutting efficiency with minimal thermal damage: Focused energy allows rapid vaporization and decomposition of tissue within a very small target volume.
• Efficient coagulation and hemostasis: Ideal for minimally invasive procedures.

Εφαρμογές:

• Varicose vein closure (EVLT)
• Tumor resection
• Surgical cutting
• Prostate surgery
• Other minimally invasive procedures

Standard Accessories

• 1 × Radial Ring Fiber (single-use consumable)

The device can be configured as a single-wavelength system (1470nm only) or combined with a 980nm laser to form a dual-wavelength system, offering greater flexibility and a wider range of clinical applications.
