980nm 1470nm 635nm Triple Wavelength EVLT Diode Laser System 30W Endovenous Vein Treatment Machine for Varicose Vein Surgery

The 980nm + 1470nm + 635nm Triple Wavelength EVLT Laser System is an advanced diode laser platform designed for minimally invasive vascular procedures, including Endovenous Laser Treatment (EVLT/EVLA), vascular coagulation, and other laser-assisted clinical applications.

Combining three complementary wavelengths, the system provides flexible energy absorption characteristics:

• 1470nm wavelength: Highly absorbed by water in vascular tissue, enabling precise vein wall heating and controlled thermal ablation.
• 980nm wavelength: More strongly absorbed by hemoglobin, supporting effective blood coagulation and vascular closure.
• 635nm wavelength: Used as a visible aiming beam to assist accurate fiber positioning during procedures.

With a 30W laser output power, the system provides stable energy delivery, efficient treatment performance, and compatibility with different fiber options.

1. Technical Principle of EVLT

How Does EVLT Work?

Endovenous Laser Treatment (EVLT/EVLA) is a minimally invasive technique that uses laser-generated thermal energy to close refluxing veins.

During treatment:

1. A laser fiber is inserted into the target vein under ultrasound guidance.
2. Laser energy is delivered through the fiber.
3. The laser energy is converted into controlled heat.
4. The vein wall is thermally damaged, causing collagen contraction and vein closure.
5. Blood flow is redirected through healthy veins.

Compared with traditional vein stripping procedures, EVLT requires only a small puncture instead of a large incision, helping reduce trauma and shorten recovery time.

2. Why Choose 980nm + 1470nm + 635nm Triple Wavelength?

1470nm — Water Absorption for Precise Vein Wall Treatment

The 1470nm wavelength has strong absorption in water-containing tissues.

Advantages:

• Concentrated energy delivery to the vein wall
• Effective thermal contraction of collagen fibers
• Reduced unwanted heat diffusion
• Lower energy requirement compared with older wavelength systems
• Designed for comfortable endovenous ablation procedures

980nm — Hemoglobin Absorption for Vascular Coagulation

The 980nm wavelength is strongly absorbed by hemoglobin.

Advantages:

• Supports blood coagulation
• Suitable for vascular closure applications
• Provides complementary treatment performance with 1470nm energy

635nm — Visible Aiming Beam

The 635nm red aiming beam allows physicians to:

• Easily identify laser fiber position
• Improve operational accuracy
• Assist precise energy delivery

3. Why Do Varicose Veins Develop?

Valve Dysfunction

Healthy veins contain one-way valves that help blood return to the heart.

When these valves become weakened or damaged:

• Blood reflux occurs
• Venous pressure increases
• Veins gradually enlarge and become twisted

Risk Factors

Common factors include:

• Long periods of standing
• Aging
• Pregnancy
• Hereditary factors
• Obesity
• Reduced physical activity

4. How EVLT Helps Treat Varicose Veins

Laser Energy Delivery

The laser fiber delivers controlled thermal energy inside the diseased vein.

Vein Wall Contraction

Laser heat causes:

• Collagen shrinkage
• Tissue contraction
• Progressive vein fibrosis and closure

Blood Flow Redirection

After closure of the abnormal vein:

• Blood naturally flows through healthier veins
• Venous circulation is improved

5. EVLT Treatment Workflow

(For trained medical professionals in qualified facilities. Procedures should follow local regulations and clinical guidelines.)

Step 1: Patient Assessment

• Ultrasound examination
• Identification of refluxing veins
• Treatment planning

Step 2: Fiber Placement

• Percutaneous access
• Fiber advancement into target vein
• Position confirmation

Step 3: Tumescent Anesthesia

Tumescent infiltration provides:

• Local anesthesia
• Vein compression around the fiber
• Thermal protection of surrounding tissues

Step 4: Laser Energy Delivery

The laser operates in:

• Continuous Wave (CW)
• Pulsed Mode

Energy is delivered while withdrawing the fiber at a controlled speed.

Step 5: Post Treatment Care

• Compression according to clinical protocol
• Early walking is generally encouraged

FAQ

1. What is EVLT laser treatment?

EVLT (Endovenous Laser Treatment) is a minimally invasive procedure that uses laser energy delivered through a fiber inserted into a diseased vein. The laser creates controlled thermal energy, causing the vein wall to contract and close. Blood is then naturally redirected through healthier veins.

2. What wavelengths does this EVLT laser system use?

This system uses three wavelengths: 980nm + 1470nm + 635nm.

• 1470nm: Mainly absorbed by water in the vein wall, providing precise thermal ablation.
