1470nm Diode Laser Machine for Spider Vein Removal

✅ Principle

*Wavelength Selection: The 1470nm wavelength falls within the near-infrared spectrum and is highly absorbed by water. Although hemoglobin absorption at this wavelength is not as strong as at 532nm or 1064nm, the 1470nm laser energy is effectively absorbed by water in the tissues surrounding blood vessels, indirectly heating and sealing abnormal vessels.

*Thermal Effect: Once absorbed by the target tissue, the laser energy generates heat, damaging the vascular endothelium and causing collagen contraction, ultimately leading to vessel closure and natural absorption by the body.

✅ Indications

*Primarily used to treat:

*Spider veins (Telangiectasias)

*Reticular veins (1–3 mm in diameter)

*Small varicose veins (often combined with foam sclerotherapy for enhanced results)

✅ Device Features (1470nm Diode Laser)

*Optical Fiber: Commonly used for endovenous procedures ( EVLT), but can also be paired with surface cooling handpieces for superficial vessels.

*Integrated Cooling: Contact cooling or cryogen spray protects the epidermis and minimizes burn risk.

*Adjustable Pulse Settings: Customizable pulse duration and fluence to suit vessel depth and diameter.

*High Safety Profile: Compared to traditional surgical stripping, it offers minimal trauma, faster recovery, and fewer complications.

✅ Treatment Procedure

*Pre-treatment Assessment: Doppler ultrasound to rule out deep venous insufficiency.

*Skin Cleansing & Vessel Marking.

*Eye Protection: Both patient and operator wear protective goggles; coupling gel applied if using non-invasive mode.

*Laser Application: Spot-by-spot or gliding technique; patients may feel mild stinging or warmth.

*Post-treatment Care: Wear medical-grade compression stockings (typically 1–2 weeks); avoid sun exposure, hot baths, and strenuous activity.

✅ Efficacy & Treatment Course

*A single session can improve 60–80% of spider veins.

*Usually requires 2–4 sessions, spaced 4–6 weeks apart.

*Full resolution may take several weeks to months (depending on individual metabolism).

✅ Precautions

*Contraindications: Pregnancy, active infection, history of deep vein thrombosis (DVT), photosensitivity disorders.

*Possible Side Effects (rare): Temporary redness, bruising, hyperpigmentation, or blistering (usually due to excessive fluence or inadequate cooling).

*Strict sun protection post-treatment is essential to prevent pigmentary changes.
