PebDiode laser 980nm + 1470nmtuaj yeem xa lub teeb laser mus rau cov ntaub so ntswg hauv kev sib cuag thiab tsis sib cuag thaum lub sijhawm phais. Cov cuab yeej siv 980nmlaser feem ntau qhia rau kev siv hauv kev txiav, txiav tawm, vaporization, ablation, hemostasis lossis coagulation ntawm cov nqaij mos hauv pob ntseg, qhov ntswg thiab caj pas thiab qhov ncauj phais (otolaryngology), kev kho hniav, kab mob plab, phais dav dav, dermatology, phais yas, podiatry, ecology, . Cov cuab yeej tau qhia ntxiv rau laser pab lipolysis. Lub cuab yeej 1470nm laser yog npaj rau kev xa tawm ntawm lub teeb laser tosoft cov ntaub so ntswg nyob rau hauv hom tsis sib cuag thaum lub sij hawm kev phais kev phais, qhia rau kev kho mob ntawm reflux ntawm saphenous veins txuam nrog varicose leeg thiab varicosities.
I. Lub Dual-Wavelength System Uas Ua Tau Zoo Li Cas?
Cov cuab yeej siv kev xaiv photothermolysis thiab sib txawv dej nqus kom ua tiav vaporization, txiav, ablation, thiab coagulation.
| Lub wavelength | Thawj Chromophore | Kev sib cuam tshuam ntawm cov ntaub so ntswg | Kev siv tshuaj kho mob |
| 980nm ua | Dej + hemoglobin | Kev nkag mus tob, muaj zog vaporization / txiav | Resection, ablation, hemostasis |
| 1470nm ua | Dej (siab nqus) | Superficial cua sov, ceev coagulation | Cov leeg kaw, precision txiav |
1. Vaporization & Txiav
980nm :ua.
Nruab nrab absorbed los ntawm dej, penetrates 3-5 mm tob.
Cov cua kub ceev (> 100 ° C) induces cov ntaub so ntswg vaporization (cellular dej boiling).
Nyob rau hauv tas li ntawd/pulsed hom, enables kev sib cuag txiav (xws li, qog, hypertrophic ntaub so ntswg).
1470nm: ua.
Kev nqus dej siab heev (10 × siab dua 980nm), txwv qhov tob rau 0.5-2 hli.
Zoo tagnrho rau precision txiav (piv txwv li, phais mucosal) nrog tsawg thermal kis.
2. Ablation & Coagulation
Kev sib xyaw ua ke:
980nm vaporizes cov ntaub so ntswg → 1470nm seals hlab ntsha (collagen shrinkage ntawm 60-70 ° C).
Txo los ntshav hauv cov txheej txheem xws li prostate enucleation lossis phais laryngeal.
3. Hemostasis Mechanism
1470nm: ua.
Coagulates sai sai cov hlab ntsha me (<3 hli) ntawm collagen denaturation thiab endothelial puas.
II. 1470nm Wavelength rau Venous Insufficiency & Varicose Veins
1. Mechanism of Action (Endovenous Laser Therapy, EVLT)
Hom phiaj:Dej hauv phab ntsa venous (tsis yog hemoglobin-dependent).
Txheej txheem:
Laser fiber insertion: Percutaneous tso rau hauv qhov zoo saphenous leeg (GSV).
1470nm laser activation: qeeb fiber ntau rub rov qab (1-2 mm / s).
Cov teebmeem thermal:
Endothelial kev puas tsuaj → vein collapse.
Collagen contraction → ruaj khov fibrosis.
2. Qhov zoo tshaj 980nm
Txo cov teeb meem (tsawg bruising, paj hlwb raug mob).
Cov nqi kaw siab dua (> 95%, ib phau ntawv Journal of Vascular Surgery).
Tsawg zog xav tau (vim kev nqus dej ntau dua).
III. Kev siv cuab yeej siv
Dual Wavelength Hloov:
Los ntawm txhais tes / nws pib xaiv hom (xws li, 980nm rau txiav → 1470nm rau sealing).
Fiber Optics:
Radial fibers (ib lub zog rau cov leeg).
Tiv tauj cov lus qhia (rau qhov tseeb incisions).
Cooling Systems:
Cua / dej txias kom tsis txhob muaj tawv nqaij kub hnyiab.
IV. Xaus
980nm :ua.Sib sib zog nqus ablation, ceev resection.
1470nm: ua.Superficial coagulation, kaw cov leeg.
Synergy:Ua ke wavelengths pab kom "txiav-thiab-seal" efficiency hauv kev phais.
Rau cov cuab yeej tshwj xeeb lossis kev tshawb fawb soj ntsuam, muab daim ntawv thov npaj (xws li, urology, phlebology).
