Ukuvula Ukuvaleka Okuphezulu, Iintlungu Ezincinci Emva Kotyando, kunye Nokuchacha Okukhawulezileyo Kwangaphandle Kwi-Phlebology Yanamhlanje
Ukungakwazi ukusebenza kakuhle kwemithambo yegazi (CVI) kunye nemithambo yegazi engaphantsi kwemilenze ichaphazela amakhulu ezigidi zabantu kwihlabathi liphela, okubangela ubunzima bemilenze engapheliyo, ukudumba, iintlungu, i-stasis dermatitis, kunye nezilonda zemithambo yegazi eziphindaphindayo. Nangona ukukrazula okuqhelekileyo (ukuqaqanjelwa okuphezulu kunye nokukrazula) kwakukhe kwasebenza njengonyango oluphambili lwezonyango, utyando lwemithambo yegazi lwanamhlanje luye lwatshintsha ngokukhawuleza lwaya kwi-endovenous thermal ablation encinci. Namhlanje,Unyango lweLaser Endovenous (EVLT / EVLA)imele umgangatho wegolide ocetyiswa yi-phlebology yamazwe ngamazwe—inika amazinga aphezulu okuvaleka, iziphumo ezibalaseleyo zobuhle, kwaye phantse akukho mntu uhlala esibhedlele.
Ukusombulula imida eqhubekayo ye-laser yokuqala ye-monochromatic—njenge-ecchymosis emva kotyando, iintlungu ezibangelwa bubushushu, kunye nemingcipheko yokuphinda ivele—i-TRIANGEL yazisa eyona nto iphambili.Inkqubo yeLaser yeDiode yotyando ye-V6 Dual-Wavelength (980nm + 1470nm),Yenzelwe ngokukodwa ngokudibeneyo neTekhnoloji ye-360° Radial Optical Fiber eyenzelwe ukuvalwa kwemithambo yegazi engenasiphako.
1. Ubudlelwane beDual-Chromophore: Ubungakanani beBiophysical obuphezulu be-980nm + 1470nm
Impumelelo esisiseko yeklinikhi ye-EVLT ixhomekeke ekuvalekeni kwe-photothermal okujoliswe kuko: ukudlulisela amandla okukhanya kumandla obushushu ukuze kuguqulwe i-collagen matrix yodonga lwemithambo (intima kunye ne-media), okubangela ukufinyela kwemithambo engapheliyo kunye nokuqhekeka kwe-fibrous okulandelayo. Iqonga le-TRIANGEL V6 lisebenzisa ubude be-wavelengths ezimbini ezihambelanayo kakhulu ukuphucula ukufunxwa kwamanzi kunye ne-hemoglobin:
*1470 nm — Ukufunxwa kwamanzi okuKhethiweyo ukuze kusetyenziswe amanzi athambileyo nangaphantsi:Amanzi yeyona chromophore iphambili kwi-endothelial lining kunye nodonga lwemithambo. Ububanzi be-1470nm bubonisa i-coefficient yokufunxwa emanzini malunga namaxesha angama-40 aphezulu kune-980nm, kunye nemiyalelo yobukhulu obuphezulu kune-810nm okanye i-1064nm. Oku kuvumela amandla obushushu ukuba agcinwe kwindawo engaphantsi kakhulu, elawulwa ngokungqongqo ngaphakathi kodonga lwemithambo. Ngenxa yoko, ukwakheka kwamaqamza omphunga kuyancitshiswa, ukucaphuka kwemithambo-luvo ye-perivascular kuyaphetshwa, kwaye i-ecchymosis emva kotyando (ukudumba) incitshiswa kakhulu.
*980 nm — Ukufunxwa kweHemoglobin ephezulu ukuze kukhawuleziswe ukujiya kunye nokujiya kweHemostasis:Ngelixa i-1470nm ilungisa i-collagen yolwakhiwo lodonga lwemithambo yegazi, i-980nm ihambelana ne-peak absorption spectrum ye-oxyhemoglobin kunye ne-deoxyhemoglobin. Oku kunika i-photocoagulation ekhawulezileyo ngaphakathi kwemithambo yegazi, kutywine imijelo yemithambo yegazi edibeneyo kwaye kuthintele ukuphuma kwegazi ngaphakathi kotyando kunye nokopha.
★ IXABISO LEKLINIKI INOMBOLO: AMANDLA APHANTSI, INTLUNGUZELO EPHANTSI
Imvumelwano yeKlinikhi: Indibaniselwano yentsebenziswano ye-980nm kunye ne-1470nm ivumela oogqirha ukuba basebenze nge-total fluence ephantsi kakhulu (iiJoules/cm) xa kuthelekiswa neeyunithi ze-980nm ezingama-single-wavelength, befikelela kwi-100% efanayo yokuvaleka kwemithambo kwangoko ngelixa benciphisa amanqaku eentlungu zesigulana (i-VAS) ngaphezulu kwe-65%.
2. I-360° Radial Optical Fiber: Ukukhupha okujikelezayo okulinganayo
Impumelelo enkulu kwi-EVLT yanamhlanje kukutshintsha ukusuka kwiifayibha zesiqhelo ezingenanto ukuya kwiifayibha ze-Radial Optical Fibers ezikhethekileyo ze-cylindrical. Iifayibha ezingenanto zitshisa amandla e-laser phambili kwi-axis yenqanawa, nto leyo edla ngokubangela ubushushu obungalinganiyo, ukuphakama kobushushu obuphezulu, kunye nomngcipheko obonakalayo wokugqobhoka kodonga lwemithambo. Ngokwahlukileyo koko, i-TRIANGEL Radial Optical Fiber yazisa i-proprism ye-silica enokurhawuzelelwa kwi-distal tip:
*Ukuhanjiswa okujikelezayo kwe-360° yokwenyani:Amandla akhutshwa ngokulinganayo kwisilinda epheleleyo ye-360-degree ethe nkqo eludongeni lwemithambo yegazi, ukuqinisekisa ukushwabana kwe-collagen ngokulinganayo kujikelezo lonke lwemithambo njengoko i-fiber itsalwa ngasemva.
*Ukususwa kokugqobhoka kunye nokuKhabhoni:Ngokuphepha ukudibana ngqo phakathi kwencam yefayibha eshushu kakhulu ebhekisa phambili kunye ne-vein intima, ukukhutshwa kwe-radial kuthintela ukutsha kodonga lwemithambo egxile kwi-focal kunye nokwanda kwebala lolusu.
*Isiqinisekiso sokuQhagamshela i-Optical (<20% yokulahlekelwa ngamandla):Iifayibha ezininzi eziqhelekileyo kwimarike zilahlekelwa kukudluliselwa kwe-optical coupling transmission okungaphezulu kwe-20%, nto leyo ebangela ukuhanjiswa kwamandla angaphantsi konyango kunye nokuvuselelwa kwemithambo yexesha elide. Inkqubo ye-TRIANGEL LASEEV iqinisekisa ukudityaniswa okuchanekileyo kwe-SMA905, iqinisekisa ukuba i-100% yamandla aqhelekileyo alinganisiweyo adluliselwa ngokupheleleyo kwicandelo lezonyango.
3. Iprotokholi yeKlinikhi eQhelekileyo yeSigulana esingaPhandle: Unyango lokuhamba-hamba, uNyango lokuhamba-hamba
Iprotokholi ye-TRIANGEL V6 EVLT yenzelwe ukwenziwa lula kwe-ambulatory phantsi kwe-anesthesia yendawo ye-tumescent. Inkqubo eqhelekileyo yokukhupha imithambo ye-saphenous ithatha imizuzu engama-25 ukuya kwengama-40 kuphela kwaye ilandela iprotokholi yeklinikhi engqongqo enamanqanaba amahlanu:
• Inyathelo 1: Ukubhoboza okukhokelwa yi-ultrasound:Ngaphantsi kwesikhokelo se-Duplex ultrasound, ukufikelela nge-percutaneous kusekwa kwi-medial malleolus okanye ngaphantsi kwedolo kusetyenziswa inaliti yokubhoboza ye-18G.
• Inyathelo lesi-2: Ukubekwa kwe-Hydrophilic Guidewire:Ucingo oluhamba ngamanzi oluyi-0.035-intshi ludluliselwa kakuhle nge-catheter lumen ukuya kwi-great saphenous vein (GSV).
• Inyathelo lesi-3: Ukulinganisa umgama ukuya kwi-SFJ:Ubude ukusuka kwindawo yokubhoboza ukuya kwiprojektha ye-saphenofemoral junction (fossa ovalis) bulinganiswa ngokuchanekileyo phantsi kwe-ultrasound.
• Inyathelo lesi-4: Ukubeka iCatheter yeenjongo ezininzi kunye neRadial Fiber:Ishelufu yokuhambisa ibekwe kwi-1.5–2.0 cm ukusuka kwi-epigastric vein junction, kwaye i-360° radial fiber ilayishiwe.
• Inyathelo lesi-5: I-Tumescent Anesthesia & Laser Ablation:Isisombululo se-cold tumescent singena ngaphakathi kwemithambo yegazi ukuze senze umqamelo wolwelo olukhuselayo kwaye siwise udonga lwemithambo kwifayibha. I-V6 diode laser isebenza kwimo ye-continuous wave (CW) njengoko ifayibha itsalwa ngokucwangcisiweyo kwi-1–2 mm/sec (target Linear Endovenous Energy Density: 50–70 J/cm).
Ulawulo Emva Kwenkqubo: Iibhandishi zokuxinzelela okanye iisokisi zokuxinzelela zonyango zeklasi yesi-II zifakwa ngoko nangoko emlenzeni onyangiweyo. Izigulane zikhuthazwa ukuba zihambe ngoko nangoko imizuzu engama-20 kwaye zinokubuyela ekhaya ngoko nangoko. Ukuxinzelela kugcinwa iintsuku ezi-7 ukuya kwezili-14. I-Duplex ultrasound elandelayo iqinisekisa i-segmental fibrosis, i-low echo, ukungaxinzeleli, kunye nokungabikho ngokupheleleyo kwe-reflux.
