Yedudiode laser 980nm+1470nminogona kuunza mwenje welaser kune yakapfava tishu mukati mekubata uye isiri yekubata modhi panguva yekuvhiya. Chishandiso ichi 980nmlaser chinowanzo kuratidzwa kuti chishandiswe mukucheka, kubvisa, vaporization, ablation, hemostasis kana coagulation yezvinyoro zvinyoro munzeve, mhino nepahuro nekuvhiya nemuromo (otolaryngology), mazino maitiro, gastroenterology, general kuvhiya, dermatology, kuvhiyiwa kwepurasitiki, podiatry, urology. Chishandiso ichi chinoratidzwa zvakare kune laser yakabatsira lipolysis. Chishandiso che1470nm laser chakagadzirirwa kuendesa laser mwenje tosoft tishu mune isiri-yekubata modhi panguva yekuvhiya yakajairika, inoratidzirwa kurapwa kwereflux yemasaphenous tsinga ane chekuita nevaricose veins uye varicosities.
I. Iyo Dual-Wavelength System Inowana Sei Zvikonzero ZveTissue?
Chishandiso chinoshandisa yakasarudzika photothermolysis uye kusiyanisa mvura kunyura kuti iwane vaporization, kucheka, ablation, uye coagulation.
| Wavelength | Primary Chromophore | Kudyidzana kweTissue | Clinical Applications |
| 980nm | Mvura + Hemoglobin | Kupinda kwakadzika, simba vaporization/kucheka | Resection, ablation, hemostasis |
| 1470nm | Mvura (yakanyanya kunyura) | Kupisa kwepamusoro, kukurumidza coagulation | Kuvharwa kwetsinga, kucheka chaiko |
1. Vaporization & Kucheka
980nm:
Kunyura zvine mwero nemvura, kunopinda kudzika 3-5 mm.
Kukurumidza kupisa (> 100 ° C) kunoita kuti tishu mhute (serura mvura kufashaira).
Mune inoenderera / pulsed modhi, inogonesa kubata kubata (semuenzaniso, mamota, hypertrophic tishu).
1470nm:
Kunyura kwakanyanya kwemvura (10 × yakakwirira kupfuura 980nm), ichidzikamisa kudzika kusvika 0.5-2 mm.
Yakanakira kucheka chaiko (semuenzaniso, kuvhiyiwa kwemucosal) nekupararira kudiki kwekupisa.
2. Ablation & Coagulation
Combined Mode:
980nm inopfungaira matishu → 1470nm seals midziyo (collagen shrinkage pa60-70 ° C).
Inoderedza kubuda ropa mumatanho akaita seprostate enucleation kana kuvhiya laryngeal.
3. Hemostasis Mechanism
1470nm:
Inokurumidza kubatanidza midziyo midiki (<3 mm) kuburikidza ne collagen denaturation uye endothelial kukuvara.
II. 1470nm Wavelength yeVenous Insufficiency & Varicose Veins
1. Mechanism of Action (Endovenous Laser Therapy, EVLT)
Chinangwa:Mvura mumadziro evhavha (kwete hemoglobin-inotsamira).
Maitiro:
Laser fiber kupinza: Percutaneous kuiswa muhombe saphenous vein (GSV).
1470nm laser activation: Slow fiber pullback (1-2 mm / s).
Thermal effects:
Endothelial kuparadzwa → kudonha kwetsinga.
Collagen contraction → zvachose fibrosis.
2. Zvakanakira Kupfuura 980nm
Zvinetso zvakaderedzwa (kunyanya kuputika, kukuvara kwetsinga).
Kuvhara kwepamusoro mitengo (> 95%, paChinyorwa cheVascular Surgery).
Simba rezasi rinodiwa (nekuda kwekukwira kwemvura kunyura).
III. Kushandiswa Kwemudziyo
Dual-Wavelength Kuchinja:
Manual/auto mode kusarudzwa (semuenzaniso, 980nm yekucheka → 1470nm yekuisa chisimbiso).
Fiber Optics:
Radial fibers (uniform simba retsinga).
Mazano ekuonana (yekunyatso cherechedzwa).
Cooling Systems:
Kutonhodza kwemhepo/mvura kudzivirira kutsva kweganda.
IV. Mhedziso
980nm:Deep ablation, kukurumidza resection.
1470nm:Superficial coagulation, kuvharwa kwetsinga.
Synergy:Yakasanganiswa wavelengths inogonesa "kucheka-uye-chisimbiso" kushanda mukuvhiya.
Kune chaiwo maparamita emudziyo kana zvidzidzo zvekiriniki, ipa iyo yakanangwa application (semuenzaniso, urology, phlebology).
