Ukuvula Ukuvaleka Okuphezulu, Ubuhlungu Obuncane Ngemva Kokuhlinzwa, Nokululama Okusheshayo Kweziguli Ezingalaliswanga Esibhedlela Sesimanje
Ukungasebenzi kahle kwemithambo yegazi okungapheli (i-CVI) kanye nemithambo yegazi ephukile yemilenze engezansi kuthinta amakhulu ezigidi zabantu emhlabeni jikelele, okubangela ukuqina kwemilenze okungapheli, ukuvuvukala, ubuhlungu, i-stasis dermatitis, kanye nezilonda zemithambo yegazi eziphindaphindayo. Nakuba ukuhlinzwa okuvamile (ukubopha okuphezulu kanye nokususa) kwake kwaba ukwelashwa okuyinhloko kwezokwelapha, ukuhlinzwa kwemithambo yegazi yesimanje kuye kwashintsha ngokunqumayo kwaya ekuhlinzeni okushisa okuncane okungena emzimbeni. Namuhla,I-Endovenous Laser Treatment (EVLT/EVLA)imelela indinganiso yegolide enconywe yisivumelwano samazwe ngamazwe se-phlebology—eletha amazinga aphezulu okuvaleka, imiphumela emihle kakhulu yobuhle, kanye nokuhlala esibhedlela cishe akukho nhlobo.
Ukuze kuxazululwe imikhawulo eqhubekayo yama-laser okuqala e-monochromatic—njenge-ecchymosis yangemva kokuhlinzwa, ubuhlungu obubangelwa ukushisa, kanye nezingozi zokuphinda kusebenze—i-TRIANGEL yethula i-flagship yayo.Uhlelo lwe-Laser lwe-Diode Yokuhlinzwa ye-V6 Dual-Wavelength (980nm + 1470nm),Yakhiwe ngokukhethekile ngokuhlanganiswa nobuchwepheshe be-360° Radial Optical Fiber obukhethekile bokuvala imithambo yegazi ngendlela engenaphutha.
1. Ukuhlangana Okubili Kwe-Chromophore: Ukuphakama Kwe-Biophysical kwe-980nm + 1470nm
Impumelelo eyisisekelo yezokwelapha ye-EVLT incike ekuvinjweni kwe-photothermal okuqondiswe kuyo: ukudlulisela amandla okukhanya kumandla okushisa ukuze kuguqulwe i-collagen matrix yodonga lwemithambo (intima kanye ne-media), okubangela ukufinyela kwemithambo okuhlala njalo kanye nokuqedwa kwe-fibrous okulandelayo. Ipulatifomu ye-TRIANGEL V6 isebenzisa amaza amabili ahambisanayo kakhulu ukuze kuthuthukiswe kokubili ukumuncwa kwamanzi kanye ne-hemoglobin:
*1470 nm — Ukumuncwa Kwamanzi Okukhethiwe Ukuze Kusetshenziswe Kalula, Ngokungajulile:Amanzi yi-chromophore evelele ku-endothelial lining kanye nodonga lwemithambo. Ubude be-wavelength obungu-1470nm bubonisa i-coefficient yokumuncwa emanzini cishe ngokuphindwe ka-40 kune-980nm, kanye nama-oda aphezulu kuno-810nm noma u-1064nm. Lokhu kuvumela amandla okushisa ukuthi agcinwe endaweni engajulile kakhulu, elawulwa ngokuqinile ngaphakathi kodonga lwemithambo. Ngenxa yalokho, ukwakheka kwamabhamuza omphunga kuyancishiswa, ukucasuka kwemizwa engaphakathi kwemithambo yegazi kuyagwenywa, futhi i-ecchymosis (ukulimaza) ngemva kokuhlinzwa incishiswa kakhulu.
*980 nm — Ukumuncwa Okuphezulu kwe-Hemoglobin ukuze kuqiniswe ngokushesha kanye ne-Hemostasis:Nakuba i-1470nm ivuselela i-collagen yesakhiwo sodonga lwemithambo yegazi, i-980nm ifana ne-peak absorption spectrum ye-oxyhemoglobin kanye ne-deoxyhemoglobin. Lokhu kuletha i-photocoagulation esheshayo ngaphakathi kwemithambo yegazi, ukuvala imifudlana yemithambo yegazi kanye nokuvimbela ukuphuma kwegazi ngesikhathi sokuhlinzwa.
★ INANI LOMTHOLAMPILO INOTHI: AMANDLA APHANSI, INDUDUZO EPHUMELELAYO
Ukuvumelana Kwezokwelapha: Inhlanganisela yokusebenzisana kwe-980nm kanye ne-1470nm ivumela odokotela abahlinzayo ukuthi basebenze nge-total fluence ephansi kakhulu (ama-Joules/cm) uma kuqhathaniswa namayunithi angu-980nm angama-wavelength angu-single, okufinyelela ukuvaleka kwemithambo yegazi okufana okungu-100% ngokushesha ngenkathi kunciphisa amaphuzu obuhlungu esigulini (i-VAS) ngaphezu kuka-65%.
2. I-Radial Optical Fiber engu-360°: Ukukhishwa Okufanayo Okuzungezayo
Intuthuko enkulu ku-EVLT yesimanje ukushintsha kusuka kuma-fiber avamile angenalutho kuya kuma-Fibers e-Radial Optical Fibers akhethekile ayindilinga. Ama-fibers angenalutho akhipha amandla e-laser phambili eceleni kwe-axis yemikhumbi, okuvame ukubangela ukushisa okungalingani, ukuphakama kokushisa okuphezulu, kanye nengozi eyaziwayo yokubhoboka kodonga lwemithambo. Ngokuphambene nalokho, i-TRIANGEL Radial Optical Fiber yethula i-micro-prism ye-silica eqondile ekhoneni elikude:
*Ukulethwa Okuyindilinga Okuyi-360° Kwangempela:Amandla akhishwa ngokulinganayo kusilinda ephelele engama-degree angu-360 eqondile odongeni lwemithambo yegazi, okuqinisekisa ukuncishiswa kwe-collagen okufanayo nxazonke kwemithambo yegazi njengoba i-fiber idonswa emuva.
*Ukususwa Kokubhoboka Nokwenziwa Kwe-Carbonization:Ngokugwema ukuthintana ngqo phakathi kwe-fibre eshisayo kakhulu eqhuma phambili kanye ne-vein intima, ukuphuma kwe-radial kuvimbela ukusha kodonga lwe-vein focal kanye nokwanda kwesikhumba.
*Isiqinisekiso Sokuxhumanisa Okubonakalayo (<20% Ukulahlekelwa Amandla):Imicu eminingi ejwayelekile emakethe ilahlekelwa ukudluliselwa kokuxhumanisa okubonakalayo okungaphezu kuka-20%, okuholela ekulethweni kwamandla angaphansi kokwelashwa kanye nokuvuselelwa kwemithambo yesikhathi eside. Uhlelo lwe-TRIANGEL LASEEV luqinisekisa ukuxhumanisa okunembile kwe-SMA905, okuqinisekisa ukuthi amandla angu-100% alinganisiwe adluliselwa engashintshi ensimini yezokwelapha.
3. Iphrothokholi Yomtholampilo Ejwayelekile: Ukunakekelwa Kweziguli Ezingena Ngokuzithandela, Ukunakekelwa Kweziguli Ezihamba Ngokuzithandela
Iphrothokholi ye-TRIANGEL V6 EVLT yenzelwe ukwenziwa okulula kokuhamba ngaphansi kwe-anesthesia yendawo ye-tumescent. Inqubo evamile yokukhipha imithambo ye-saphenous idinga imizuzu engama-25 kuya kwengama-40 kuphela futhi ilandela inqubo eqinile yezokwelapha enezigaba ezinhlanu:
• Isinyathelo 1: Ukubhoboza Okuqondiswa yi-Ultrasound:Ngaphansi kwesiqondiso se-Duplex ultrasound, ukufinyelela kwe-percutaneous kuqinisekiswa ku-medial malleolus noma ngaphansi kwedolo kusetshenziswa inaliti yokubhoboza engu-18G.
• Isinyathelo 2: Ukubekwa kwe-Hydrophilic Guidewire:Ucingo oluqondisa amanzi oluyi-0.035-intshi ludluliselwa kahle nge-catheter lumen luye ku-great saphenous vein (GSV).
• Isinyathelo 3: Ukulinganisa Ibanga kuya ku-SFJ:Ubude kusukela endaweni yokubhoboza kuya ekubonisweni kwe-saphenofemoral junction (fossa obalis) kulinganiswa ngokunembile ngaphansi kwe-ultrasound.
• Isinyathelo 4: Ukubeka I-Catheter Yezinhloso Eziningi kanye Ne-Radial Fiber:Igobolondo lokubeletha libekwe ku-1.5-2.0 cm ukusuka ekhoneni lemithambo ye-epigastric, futhi i-fiber ye-radial engu-360° ilayishiwe.
• Isinyathelo sesi-5: I-Tumescent Anesthesia & Laser Ablation:Isixazululo esibandayo se-tumescent singena ngaphakathi kwemithambo yegazi ukuze sakhe umcamelo woketshezi oluvikelayo bese sigoqa udonga lwemithambo lungene ku-fiber. I-laser ye-V6 diode iyasebenza kumodi ye-continuous wave (CW) njengoba i-fiber idonswa ngokuhlelekile emuva ku-1–2 mm/sec (target Linear Endovenous Energy Density: 50–70 J/cm).
Ukuphathwa Kwangemva Kwenqubo: Amabhandeshi okucindezela noma amasokisi okucindezela ezokwelapha ekilasini lesibili afakwa ngokushesha emlenzeni olashwe. Iziguli zikhuthazwa ukuba zihambe ngokushesha imizuzu engama-20 futhi zingabuyela ekhaya ngokushesha. Ukucindezela kugcinwa izinsuku eziyi-7 kuya kweziyi-14. I-Duplex ultrasound elandelayo iqinisekisa i-segmental fibrosis, i-low echo, ukungacindezeli, kanye nokungabikho ngokuphelele kwe-reflux.
