Kuvhura Kuvharirwa Kwepamusoro, Marwadzo Mashoma Mushure mekuvhiyiwa, uye Kupora Kwekukurumidza Kunze MuPhlebology Yemazuva Ano
Kusakwana kwetsinga dzeropa kwenguva refu (CVI) uye mitsipa yeropa iri pasi pemakumbo kunokanganisa mazana emamiriyoni evanhu pasi rose, zvichikonzera kurema kwetsinga kwenguva refu, kuzvimba, kurwadziwa, stasis dermatitis, uye maronda eropa anodzokororwa. Kunyange zvazvo kubvisa tsinga dzeropa nenzira yechinyakare (high ligation uye kubvisa tsinga) kwaimboshandiswa senzira huru yekurapa, kuvhiyiwa kwetsinga dzeropa kwemazuva ano kwachinja zvakanyanya kuenda kukubvisa tsinga dzeropa zvishoma nezvishoma. Nhasi,Endovenous Laser Kurapa (EVLT / EVLA)inomiririra mwero wegoridhe unokurudzirwa nesangano repasi rose re phlebology—zvichipa mwero wepamusoro wekuvharika kwemasero, mhedzisiro yakanaka yekushongedza, uye hapana kugara muchipatara.
Kuti igadzirise miganhu inogara iripo ye lasers dzekutanga dze monochromatic—dzakadai se ecchymosis mushure mekuvhiyiwa, kurwadziwa kunokonzerwa nekupisa, uye njodzi dzekugadzirisazve masero—TRIANGEL yatanga kambani yayo huru.Sisitimu yeLaser yeDiode yekuvhiya yeV6 Dual-Wavelength (980nm + 1470nm),Yakagadzirwa pamwe chete ne360° Radial Optical Fiber Technology yekudzivirira tsinga dzeropa zvakanaka.
1. Dual-Chromophore Affinity: Kubudirira kweBiophysical kwe980nm + 1470nm
Kubudirira kukuru kweEVLT mukurapa kunobva pakuvharika kwechiedza chezuva: kuendesa simba remagetsi musimba rekupisa kuti ribvise collagen matrix yemadziro etsinga (intima ne media), zvichiita kuti tsinga dzigare dzakasimba uye fibrous obliteration iite. Chikuva cheTRIANGEL V6 chinoshandisa mawavelength maviri anoenderana zvakanyanya kuti zviite kuti mvura nehemoglobin zvinyatsobuda zvakanaka:
*1470 nm — Kunyudzwa kwemvura kwekusarudza kuti iite zvinyoro nyoro uye isina kudzika:Mvura ndiyo chromophore inonyanya kushandiswa mu endothelial lining uye mutsinga dzemuviri. Hurefu hwe1470nm hunoratidza kuti mvura inogona kunyudzwa mumvura kanenge ka40 kupfuura 980nm, uye hukuru hwayo hwakakwira kupfuura 810nm kana 1064nm. Izvi zvinoita kuti simba rekupisa rigare munzvimbo isina kudzika zvakanyanya, inodzorwa zvakasimba mukati metsinga dzemuviri. Nekuda kweizvozvo, kuumbwa kwemabubble emhepo kunoderedzwa, kutsamwa kwetsinga dzeropa kunodziviswa, uye kukuvara kwemuviri mushure mekuvhiyiwa kunodzikira zvakanyanya.
*980 nm — Kunyudzwa kweHemoglobin Yakawanda Kuti Kugwinya Kukurumidze uye Kupera Kweropa:Kunyange hazvo 1470nm ichigadzirisa collagen yemadziro etsinga, 980nm inoenderana nehupamhi hwepamusoro hweoxyhemoglobin nedeoxyhemoglobin. Izvi zvinoita kuti ropa ripinde mumuviri rionekwe nekukurumidza, zvichivhara migero yeropa pamwe nekudzivirira kubuda ropa mukati mekuvhiyiwa.
★ CHINOKOSHA CHEKURINIKI: SIMBA RAKADERERA, NYARADZO YEPAMUSORO
Kubvumirana Kwekiriniki: Musanganiswa we980nm ne1470nm unobvumira vanachiremba kuti vashandise fluence yakaderera zvakanyanya (Joules/cm) zvichienzaniswa nemayuniti e980nm ane wavelength imwe chete, zvichiita kuti tsinga dzeropa dzivharwe ne100% panguva imwe chete ukuwo zvichideredza marwadzo evarwere (VAS) neanopfuura 65%.
2. 360° Radial Optical Fiber: Yakaenzana
Kubudirira kukuru muEVLT yemazuva ano kuchinja kubva kufibers dzemazuva ano dzisina tambo kuenda kuFray Optical Fibers dzakagadzirwa necylindrical cylindrical. Mashizha asina tambo anopisa simba relaser mberi achitevedza axis yemudziyo, izvo zvinowanzo kukonzera kupisa kusina kuenzana, kupisa kwakanyanya, uye njodzi yekuboorwa kwemadziro etsinga. Kusiyana neizvi, TRIANGEL Radial Optical Fiber inoburitsa micro-prism ye refractive refractive silica pamucheto we distal:
*Kutumirwa Kwechokwadi Kwe360° Kutenderera:Simba rinoburitswa zvakaenzana mu cylinder yakakwana ye360-degree yakatwasuka kumadziro etsinga, zvichiita kuti collagen itsvedzerere zvakaenzana kutenderedza tsinga yese sezvo fiber ichidhonzwa kumashure.
*Kubviswa Kwekuboorwa uye Kugadziriswa Kwekabhoni:Nekudzivirira kusangana zvakananga pakati pemusoro wefiber unopisa zvikuru nevein intima, kubuda kwe radial kunodzivirira kutsva kwemadziro evein focal uye hyperpigmentation yeganda.
*Gwaro reKubatanidza Maziso (<20% Kurasikirwa Nesimba):Mafiber mazhinji ari mumusika anorasikirwa ne optical coupling transmission inodarika 20%, zvichikonzera kuendeswa kwesimba re sub-therapeutic uye kudzorerwa kwetsinga kwenguva refu. Sisitimu yeTRIANGEL LASEEV inovimbisa kusanganiswa kwakarurama kweSMA905, ichivimbisa kuti 100% yesimba rakagadziriswa rinotamiswa rakazara mumunda wekiriniki.
3. Maitiro Ekurapa Akajairika: Kutarisirwa Kwevarwere Vanopinda Nenguva Dzose, Kutarisirwa Kwevarwere Vanofamba Nenguva Dzose
Nzira yeTRIANGEL V6 EVLT yakagadzirwa kuti ishande zviri nyore pasi peanesthesia yemudumbu. Nzira yekubvisa tsinga dzemutsinga dzinotora maminetsi makumi maviri nemashanu kusvika makumi mana chete uye inotevera nzira yekiriniki ine matanho mashanu:
• Danho 1: Kuboorwa Kunotungamirirwa neUltrasound:Nekutungamirirwa neDuplex ultrasound, nzira yekupinda muganda inoonekwa pa medial malleolus kana pasi pebvi uchishandisa tsono ye18G yekuboorwa.
• Danho rechipiri: Kuiswa kweWaya yeMazano inonyungudutsa mvura:Waya yekufambisa inoyerera ne hydrophilic ine 0.035-inch inofambiswa zvakanaka nepa catheter lumen ichipinda mu great saphenous vein (GSV).
• Danho rechitatu: Kuyera Kureba kusvika kuSFJ:Kureba kubva panoboorwa kusvika panowanikwa saphenofemoral junction (fossa obalis) kunoongororwa nemazvo pasi pe ultrasound.
• Danho rechina: Kuisa Catheter yeZvinangwa Zvakawanda & Radial Fiber Positioning:Chivharo chekubereka chiri panzvimbo iri 1.5–2.0 cm kure nepanosangana tsinga dzemudumbu, uye 360° radial fiber inoiswa.
• Danho 5: Tumescent Anesthesia & Laser Ablation:Mvura inotonhora inopinzwa mukati meropa kuti igadzire mutsindo wekudzivirira uye inokanda madziro etsinga pafiber. V6 diode laser inobatidzwa mu continuous wave (CW) mode sezvo fiber ichidzoserwa kumashure pa 1–2 mm/sec (target Linear Endovenous Energy Density: 50–70 J/cm).
Kutarisirwa Kwemashure meKushandiswa: Mabhandeji ekudzvanya kana masokisi ekudzvanya ekirasi yechipiri anoiswa ipapo ipapo pagumbo rinorapwa. Varwere vanokurudzirwa kufamba ipapo ipapo kwemaminitsi makumi maviri uye vanogona kudzoka kumba ipapo ipapo. Kudzvanya kunochengetwa kwemazuva manomwe kusvika gumi nemana. Duplex ultrasound inotevera inosimbisa segmental fibrosis, low echo, non-compressibility, uye kusavapo zvachose kwe reflux.
