YethuI-diode laser 980nm + 1470nminokuhanjiswa ukukhanya kwelaser kwizicubu ezithambileyo kunxibelelwano kunye nemowudi yokungaqhagamshelani ngexesha leenkqubo zotyando. Isixhobo se-980nmlaser ngokuqhelekileyo siboniswa ukuba sisetyenziswe ekusikeni, ukusika, ukufunxa, ukukhupha, ukopha okanye ukudityaniswa kwezicubu ezithambileyo endlebeni, empumlweni nasemqaleni kunye notyando lomlomo (otolaryngology), iinkqubo zamazinyo, i-gastroenterology, utyando jikelele, i-dermatology, utyando lweplastiki, i-podiatry, i-urology. Isixhobo sikwaboniswa ngakumbi kwi-laser encedisa i-lipolysis. Isixhobo se-laser ye-1470nm senzelwe ukuhanjiswa kwe-laser light tosoft tissue kwimodi engadibananga ngexesha leenkqubo zotyando jikelele, eziboniswe ukunyangwa kwe-reflux ye-saphenous veins ehambelana ne-varicose veins kunye ne-varicosities.
I. Ingaba iSistim ye-Dual-Wavelength iZiphumeza njani ii-Tissue Effects?
Isixhobo sisebenzisa i-photothermolysis ekhethiweyo kunye nokwahlukana kwamanzi ukufunxa ukufezekisa ukuphunga, ukusika, ukukhupha, kunye nokudibanisa.
| Ubude bamaza | I-Chromophore yokuqala | Ukusebenzisana kwezicubu | Izicelo zeklinikhi |
| 980nm | Amanzi + IHemoglobin | Ukungena nzulu, umphunga onamandla/ukusika | Ukususwa, ukuchithwa, i-hemostasis |
| 1470nm | Amanzi (ukufunxa okuphezulu) | Ukufudumeza okuphezulu, ukuqina ngokukhawuleza | Ukuvalwa kwemithambo, ukusika ngokuchanekileyo |
1. Ukwenziwa ngumphunga kunye nokusika
980nm:
Ukufunxa ngokuphakathi emanzini, ukungena kwi-3-5 mm ubunzulu.
Ukufudumeza okukhawulezayo (> 100 ° C) kubangela i-tissue vaporization (ukubilisa kwamanzi eselula).
Kwimo eqhubekayo / ye-pulsed, yenza ukusika uqhagamshelwano (umzekelo, amathumba, izicubu ze-hypertrophic).
1470nm:
Ukufunxwa kwamanzi aphezulu kakhulu (10× ngaphezulu kwe-980nm), ukunciphisa ubunzulu kwi-0.5-2 mm.
Ilungele ukusika ngokuchanekileyo (umzekelo, utyando lwe-mucosal) kunye nokusabalalisa okuncinci kwe-thermal.
2. I-Ablation & Coagulation
Imo edityanisiweyo:
I-980nm ikhupha izicubu → i-1470nm seals izitya (i-collagen shrinkage kwi-60-70 ° C).
Yehlisa ukopha kwiinkqubo ezifana ne-prostate enucleation okanye utyando lwelaryngeal.
3. I-Hemostasis Mechanism
1470nm:
Idibanisa ngokukhawuleza iinqanawa ezincinci (<3 mm) nge-collagen denaturation kunye nomonakalo we-endothelial.
II. I-1470nm ubude bobude be-Venous Insufficiency & Varicose Veins
1. Indlela yokuSebenza (Endovenous Laser Therapy, EVLT)
Ekujoliswe kuko:Amanzi kudonga lwe-venous (ayixhomekekanga kwi-hemoglobin).
Inkqubo:
Ukufakwa kwe-laser fiber: Ukubekwa kwePercutaneous kumthambo omkhulu we-saphenous (GSV).
Ukusebenza kwe-laser ye-1470nm: I-fiber epholileyo i-pullback (1-2 mm / s).
Iziphumo zobushushu:
Ukutshatyalaliswa kwe-Endothelial → ukuwa komthambo.
I-Collagen contraction → i-fibrosis esisigxina.
2. Izinto eziluncedo Ngaphezu kwe-980nm
Iingxaki ezincitshisiweyo (ukubetha kancinci, ukulimala kwemithambo-luvo).
Amazinga aphezulu okuvala (> 95%, kwiJournal ye-Vascular Surgery).
Amandla asezantsi afunekayo (ngenxa yokufunxa okuphezulu kwamanzi).
III. Ukuphunyezwa kwesixhobo
Ukutshintsha kobude obubini:
Ukukhetha indlela yokwenziwa ngesandla/ezenzekelayo (umzekelo, i-980nm yokusika → 1470nm yokutywinwa).
IFiber Optics:
Imicu yeRadial (amandla afanayo emithanjeni).
Iingcebiso zoQhagamshelwano (ukwenzela izikeko ezichanekileyo).
Iinkqubo zokupholisa:
Ukupholisa umoya/amanzi ukuthintela ukutsha kwesikhumba.
IV. Ukuqukumbela
980nm:Ukukhutshwa okunzulu, ukukhutshwa ngokukhawuleza.
1470nm:I-coagulation ephezulu, ukuvalwa kwemithambo.
I-Synergy:Ubude bamaza obudityanisiweyo buvumela "ukunqunyulwa-kunye-netywina" ukusebenza kakuhle kutyando.
Ngeeparamitha zesixhobo esithile okanye izifundo zeklinikhi, bonelela ngosetyenziso olucetywayo (umzekelo, iurology, phlebology).
