Eyethui-diode laser 980nm+1470nmingakwazi ukulethwa kokukhanya kwe-laser esicutshini esithambile endaweni yokuxhumana kanye nemodi yokungathintani phakathi nezinqubo zokuhlinzwa. I-980nmlaser yedivayisi ngokuvamile iboniswa ukuze isetshenziswe ekusikeni, ekuhlinzeni, ekuhwameni, ekukhipheni igazi, ukopha igazi noma ukujiya kwezicubu ezithambile endlebeni, ekhaleni nasemphinjeni kanye nokuhlinzwa komlomo (i-otolaryngology), izinqubo zamazinyo, i-gastroenterology, ukuhlinzwa okuvamile, i-dermatology, ukuhlinzwa kwepulasitiki, i-podiatry, i-urology. Idivayisi iphinde ikhonjiswe nge-laser lipolysis. I-laser yedivayisi engu-1470nm ihloselwe ukulethwa kwezicubu ezithambile ze-laser kwimodi yokungathinteki phakathi nezinqubo zokuhlinzwa okuvamile, eziboniswa ekwelapheni i-reflux ye-saphenous veins ehambisana ne-varicose veins kanye ne-varicosities.
I. I-Dual-Wavelength System Iyithola Kanjani Imithelela Yezicubu?
Idivayisi isebenzisa i-photothermolysis ekhethiwe kanye nokumuncwa kwamanzi okuhlukile ukuze kufinyelele ukuhwamuka, ukusika, ukukhipha, kanye nokujiya.
| Ubude begagasi | I-Chromophore eyinhloko | Ukusebenzisana Kwezicubu | Izicelo Zomtholampilo |
| 980nm | Amanzi + I-Hemoglobin | Ukungena okujulile, ukuhwamuka okunamandla/ukusika | Ukususwa, ukukhishwa, i-hemostasis |
| 1470nm | Amanzi (ukumuncwa okuphezulu) | Ukushisa okukha phezulu, ukuhlangana ngokushesha | Ukuvalwa kwemithambo, ukusika ngokunemba |
1. Ukushisa nokusika
980nm:
Imuncwa ngokusesilinganisweni ngamanzi, ingena ukujula okungama-3-5 mm.
Ukushisa okusheshayo (>100°C) kubangela ukuhwamuka kwezicubu (ukubilisa kwamanzi amaselula).
Kumodi eqhubekayo/i-pulsed, inika amandla ukusika othintana naye (isb, izimila, izicubu ze-hypertrophic).
1470nm:
Ukumuncwa kwamanzi okuphezulu kakhulu (10× ngaphezulu kuka-980nm), okukhawulela ukujula ku-0.5–2 mm.
Ilungele ukusikwa okunembayo (isb, ukuhlinzwa kolwelwesi lwamafinyila) okunokusabalalisa okushisayo okuncane.
2. I-Ablation & Coagulation
Imodi Ehlanganisiwe:
I-980nm ihwamulisa izicubu → 1470nm seals imikhumbi (collagen shrinkage at 60-70°C).
Yehlisa ukopha ezinqubweni ezifana ne-prostate enucleation noma ukuhlinzwa kwe-laryngeal.
3. I-Hemostasis Mechanism
1470nm:
Ibopha ngokushesha imikhumbi emincane (<3 mm) nge-collagen denaturation kanye nokulimala kwe-endothelial.
II. I-1470nm Wavelength yokungasebenzi kahle kwe-Venous & Varicose Veins
1. Indlela Yesenzo (Endovenous Laser Therapy, EVLT)
Ithagethi:Amanzi odongeni lwe-venous (hhayi ku-hemoglobin).
Inqubo:
Ukufakwa kwe-laser fiber: Ukubekwa kwe-Percutaneous emthanjeni omkhulu we-saphenous (GSV).
Ukwenziwa kwe-laser engu-1470nm: I-fiber pullback enensayo (1–2 mm/s).
Imiphumela yokushisa:
Ukubhujiswa kwe-Endothelial → ukuwa komthambo.
Ukufinyela kwe-collagen → i-fibrosis engapheli.
2. Izinzuzo Ngaphezu kuka-980nm
Izinkinga ezincishisiwe (ukulimala okuncane, ukulimala kwezinzwa).
Amazinga aphezulu okuvala (>95%, ngeJournal of Vascular Surgery).
Amandla aphansi adingekayo (ngenxa yokumuncwa kwamanzi aphezulu).
III. Ukwenziwa Kwedivayisi
Ukushintsha i-Dual-Wavelength:
Ukukhetha imodi eyenziwa mathupha/ezenzakalelayo (isb, 980nm yokusika → 1470nm yokuvala).
I-Fiber Optics:
Ama-radial fibers (amandla afanayo emithanjeni).
Amathiphu okuxhumana (ukuthola imininingwane eqondile).
Amasistimu wokupholisa:
Ukupholisa komoya/amanzi ukuvikela ukusha kwesikhumba.
IV. Isiphetho
980nm:Ukukhishwa okujulile, ukukhishwa ngokushesha.
1470nm:I-coagulation ephezulu, ukuvalwa kwemithambo.
I-Synergy:Amaza amaza ahlanganisiwe anika amandla "ukusika nokuvalwa" ukusebenza kahle ekuhlinzeni.
Ngamapharamitha wedivayisi ethile noma izifundo zomtholampilo, hlinzeka ngohlelo oluhlosiwe (isb, i-urology, i-phlebology).
