Muchina uyu unoratidzwawo kune laser assisted lipolysis. Laser yemuchina uyu ye1470nm yakagadzirirwa kuendesa chiedza chelaser kunyama yakapfava mukubata panguva yekuvhiyiwa kwakajairika, inoratidzwa kurapa reflux yeropa resaphenous rine chekuita neropa rakapfava uye varicosities.
I. Sisitimu yeDual-Wavelength Inowana Sei Mhedzisiro yeTishu?
Mudziyo uyu unoshandisa nzira yekusarudza photothermolysis uye nzira yekubvisa mvura yakasiyana-siyana kuti upfuure, ucheke, ubvise, uye uvhare.
| Kureba kwewave | Chromophore Yekutanga | Kudyidzana kweTishu | Maitiro Ekurapa |
| 980nm | Mvura + Hemoglobin | Kupinda kwakadzika, kupwanya/kucheka kwakasimba | Kubviswa kwemasero, kubviswa kwemasero, kubviswa kwemasero eropa |
| 1470nm | Mvura (inonyudzwa zvakanyanya) | Kupisa kwekunze, kukurumidza kuonda | Kuvhara tsinga, kucheka nemazvo |
1. Kupisa & Kucheka
980nm:
Inonyudzwa zvishoma nemvura, inopinda mugomba rakadzika 3–5 mm.
Kupisa nekukurumidza (>100°C) kunokonzera kufashaira kwemuviri (mvura inofashaira mumasero).
Munzira inoenderera mberi/inopusha, inobvumira kucheka kwekubata (semuenzaniso, bundu, hypertrophic tissue).
1470nm:
Mvura inonyudzwa zvakanyanya (10× yakakwirira kupfuura 980nm), ichideredza kudzika kusvika 0.5–2 mm.
Yakanakira kucheka nemazvo (semuenzaniso, kuvhiyiwa kwemucosal) pasina kupisa kwakanyanya.
2. Kubvisa & Kusunga Mazino
Maitiro Akasanganiswa:
980nm inopfavisa tishu → 1470nm inovhara tsinga (collagen shrinkage pa60–70°C).
Inoderedza kubuda ropa mumabasa akadai sekubvisa masero emudumbu kana kuvhiyiwa kwepaburi.
3. Maitiro eHemostasis
1470nm:
Inokurumidza kuomesa tsinga diki (<3 mm) kuburikidza nekuchinja kwecollagen uye kukuvara kwe endothelial.
II. 1470nm Wavelength yeKusakwana kweVenous & Varicose Veins
1. Maitiro Ekuita (Endovenous Laser Therapy, EVLT)
Chinangwa:Mvura iri mutsinga dzeropa (isingatsamiri hemoglobin).
Maitiro:
Kuiswa kwefiber nelaser: Kuiswa kwepercutaneous mu great saphenous vein (GSV).
Kushanda kwelaser kwe1470nm: Kudhonzwa kwefiber zvishoma nezvishoma (1–2 mm/s).
Mhedzisiro yekupisa:
Kuparadzwa kweEndothelial → kuputsika kwetsinga.
Kudzikira kweCollagen → fibrosis isingaperi.
2. Zvakanakira Kupfuura 980nm
Matambudziko akaderera (kukuvadzwa kushoma, kukuvara kwetsinga).
Mwero wepamusoro wekuvharika kweropa (>95%, kubva paJournal of Vascular Surgery).
Simba shoma rinodiwa (nekuda kwekuwanda kwemvura inonwiwa).
III. Kushandiswa kweMudziyo
Kuchinja KwemaWavelength Aviri:
Sarudzo yemodhi yemaoko/otomatiki (semuenzaniso, 980nm yekucheka → 1470nm yekuvhara).
Fiber Optics:
Fiber dzemagetsi (simba rakafanana retsinga).
Mazano ekubata ganda (kuti uwane macheko chaiwo).
Masisitimu Ekutonhodza:
Kutonhodza mhepo/mvura kudzivirira kutsva kweganda.
IV. Mhedziso
980nm:Kubvisa ganda zvakadzika, kubviswa nekukurumidza.
1470nm:Kuvhara kwemuviri, kuvharika kwetsinga.
Kubatana:Mawaya akabatana anoita kuti "kucheka-nekuvhara" kushande zvakanaka mukuvhiya.
Kune maparameter chaiwo emuchina kana zvidzidzo zvekiriniki, ipai mashandisirwo aunoda (semuenzaniso, urology, phlebology).
