Kutsegula Kutsekedwa Kwabwino Kwambiri, Kupweteka Kochepa Pambuyo pa Opaleshoni, ndi Kuchira Mwachangu kwa Odwala Osapita Kunja mu Phlebology Yamakono
Matenda a chronic venous insufficiency (CVI) ndi mitsempha ya varicose ya m'munsi mwa miyendo zimakhudza anthu mamiliyoni ambiri padziko lonse lapansi, zomwe zimayambitsa kulemera kwa miyendo, kutupa, kupweteka, stasis dermatitis, ndi zilonda zam'mimba zomwe zimabwerezabwereza. Ngakhale kuti opaleshoni yachikhalidwe (high logation and stripping) inali chithandizo chachikulu chachipatala, opaleshoni yamakono ya mitsempha yasintha kwambiri kukhala yochepetsera kutentha kwa endovenous. Masiku ano,Endovenous Laser Chithandizo (EVLT / EVLA)ikuyimira muyezo wagolide womwe umavomerezedwa ndi mgwirizano wapadziko lonse wa phlebology—wopereka kuchuluka kwa kutsekedwa kwa ziwiya, zotsatira zabwino kwambiri pakukongoletsa, komanso pafupifupi palibe wodwala amene amakhala kuchipatala.
Pofuna kuthetsa zofooka zomwe zimachitika chifukwa cha ma lasers oyambirira a monochromatic—monga ecchymosis pambuyo pa opaleshoni, ululu wobwera chifukwa cha kutentha, ndi zoopsa zobwezeretsanso khungu—TRIANGEL yayambitsa ntchito yake yapadera.Dongosolo la Laser la V6 la Ma Wavelength Awiri (980nm + 1470nm),Yapangidwa makamaka pamodzi ndi ukadaulo wa 360° Radial Optical Fiber kuti iteteze mitsempha yamagazi popanda vuto lililonse.
1. Kugwirizana kwa Dual-Chromophore: Kupambana kwa Biophysical kwa 980nm + 1470nm
Kupambana kwakukulu kwa EVLT kuchipatala kumadalira pa kutsekedwa kwa photothermal: kusamutsa mphamvu ya kuwala kukhala mphamvu ya kutentha kuti iwononge collagen matrix ya khoma la mitsempha (intima ndi media), zomwe zimapangitsa kuti mitsempha yamagazi ikhale yokhazikika komanso kuti fibrous iwonongeke. Pulatifomu ya TRIANGEL V6 imagwiritsa ntchito mafunde awiri ogwirizana kwambiri kuti iwonjezere kuyamwa kwa madzi ndi hemoglobin:
*1470 nm — Kusankha Madzi Omwe Amayamwa Kuti Azigwira Ntchito Mofatsa, Mosaya:Madzi ndiye chromophore yodziwika bwino mu endothelial lining ndi khoma la mitsempha. Kutalika kwa mafunde a 1470nm kumasonyeza kuti madzi amayamwa bwino nthawi 40 kuposa 980nm, ndipo ndi okwera kuposa 810nm kapena 1064nm. Izi zimathandiza kuti mphamvu ya kutentha ikhale pamalo osaya kwambiri komanso olamulidwa bwino mkati mwa khoma la mitsempha. Chifukwa chake, kupangika kwa thovu la nthunzi kumachepa, kuyabwa kwa mitsempha ya m'mitsempha kumapewedwa, ndipo ecchymosis (kutupa) pambuyo pa opaleshoni imachepa kwambiri.
*980 nm — Kuchuluka kwa Hemoglobin kuti magazi azitsekeka mwachangu komanso kuti magazi azitsekeka:Ngakhale kuti 1470nm imakonzanso kapangidwe ka kolajeni ya khoma la mitsempha yamagazi, 980nm imafanana ndi kuchuluka kwa okosijeni ndi deoxyhemoglobin. Izi zimapangitsa kuti magazi azituluka nthawi yomweyo m'mitsempha yamagazi, kutseka mitsinje yamagazi komanso kupewa kutuluka magazi mkati mwa opaleshoni.
★ CHIDZIWITSO CHA CHALITALA: MPAMVU YOCHEPA, CHITONTHOZO CHAPAMWAMBA
Kugwirizana kwachipatala: Kuphatikizana kwa 980nm ndi 1470nm kumalola madokotala opaleshoni kugwira ntchito pamlingo wotsika kwambiri (Joules/cm) poyerekeza ndi mayunitsi a 980nm okhala ndi mafunde amodzi, zomwe zimapangitsa kuti mitsempha yofanana ikhale yotsekedwa nthawi yomweyo 100% pomwe kuchepetsa ululu wa odwala (VAS) ndi oposa 65%.
2. 360° Radial Optical Fiber: Uniform Circumferential Emission
Kupita patsogolo kwakukulu mu EVLT yamakono ndi kusintha kuchokera ku ulusi wamba wopanda nsonga kupita ku ulusi wapadera wa cylindrical Radial Optical Fibers. Ulusi wopanda nsonga umatulutsa mphamvu ya laser patsogolo motsatira mzere wa chotengera, zomwe nthawi zambiri zimayambitsa kutentha kosafanana, kutentha kwakukulu, komanso chiopsezo chodziwika cha kubowoka kwa khoma la mitsempha. Mosiyana ndi zimenezi, TRIANGEL Radial Optical Fiber imayambitsa micro-prism ya silica yomwe ili pafupi ndi nsonga:
*Kutumiza Kozungulira Koona kwa 360°:Mphamvu imatulutsidwa mofanana mu silinda yonse ya madigiri 360 yolunjika ku khoma la mitsempha yamagazi, kuonetsetsa kuti kolajeni ikuchepa mozungulira mtsempha wonse pamene ulusi ukukokedwa kumbuyo.
*Kuchotsa Kuboola ndi Kutulutsa Kaboni:Mwa kupewa kukhudzana mwachindunji pakati pa nsonga ya ulusi wotentha kwambiri ndi mtsempha wa intima, kutulutsa kwa radial kumaletsa kupsa kwa khoma la mtsempha wa focal komanso kufalikira kwa pigment pakhungu.
*Chitsimikizo Cholumikizira Ma Optical (<20% Kutaya Mphamvu):Ulusi wambiri womwe ulipo pamsika umataya mphamvu zolumikizirana ndi kuwala zopitilira 20%, zomwe zimapangitsa kuti mphamvu yotumizirana ndi chithandizo chamankhwala iperekedwe komanso kuti mitsempha ibwererenso m'malo mwake kwa nthawi yayitali. Dongosolo la TRIANGEL LASEEV limatsimikizira kulumikizana kolondola kwa SMA905, kuonetsetsa kuti 100% ya mphamvu yokhazikika imasamutsidwa bwino kupita kuchipatala.
3. Ndondomeko Yovomerezeka ya Zachipatala Zoperekedwa kwa Odwala Osapita Kunja: Chisamaliro Choyenda Panja, Choyenda Panja Chopita Kunja
Njira ya TRIANGEL V6 EVLT yapangidwa kuti igwire ntchito mophweka pogwiritsa ntchito mankhwala oletsa ululu am'deralo. Njira yodziwika bwino yochotsera mitsempha ya saphenous imatenga mphindi 25 mpaka 40 zokha ndipo imatsatira njira yokhwima yachipatala ya magawo asanu:
• Gawo 1: Kubowola Kotsogozedwa ndi Ultrasound:Motsogozedwa ndi ultrasound ya Duplex, njira yolowera m'thupi imakhazikika pa medial malleolus kapena pansi pa bondo pogwiritsa ntchito singano ya 18G yoboola.
• Gawo 2: Kuyika kwa waya wotsogolera madzi:Waya wotsogolera wa mainchesi 0.035 wophiphiritsa umapititsidwa bwino kudzera mu catheter lumen kupita mu great saphenous vein (GSV).
• Gawo 3: Kuyeza Mtunda Kupita ku SFJ:Kutalika kuchokera pamalo obowoledwa mpaka pamalo owonetsera malo olumikizirana a saphenofemoral (fossa ovalis) kumayesedwa bwino pogwiritsa ntchito ultrasound.
• Gawo 4: Kuyika Catheter Yogwiritsidwa Ntchito Zambiri & Radial Fiber Positioning:Chigoba choberekera chili pamtunda wa 1.5–2.0 cm kuchokera ku malo olumikizirana mitsempha ya epigastric, ndipo ulusi wa radial wa 360° umayikidwa.
• Khwerero 5: Tumescent Anesthesia & Laser Ablation:Njira yozizira yotulutsira madzi imalowetsedwa mkati mwa mitsempha kuti ipange khushoni yoteteza madzi ndikugwetsa khoma la mitsempha pa ulusi. Laser ya V6 diode imayatsidwa mu mawonekedwe a continuous wave (CW) pamene ulusi umakokedwa mmbuyo mwadongosolo pa 1–2 mm/sec (target Linear Endovenous Energy Density: 50–70 J/cm).
Kusamalira Pambuyo pa Njira: Mabandeji oponderezedwa kapena masokisi oponderezedwa a kalasi yachiwiri amaikidwa nthawi yomweyo pa mwendo wochiritsidwa. Odwala amalimbikitsidwa kuti aziyenda nthawi yomweyo kwa mphindi 20 ndipo amatha kubwerera kunyumba nthawi yomweyo. Kuponderezedwa kumapitilira kwa masiku 7 mpaka 14. Kujambula kwa Duplex ultrasound kotsatira kumatsimikizira kuti segmental fibrosis, low echo, kusaponderezedwa, komanso kusowa kwa reflux konse.
