Gufungura ipfunwe ry'umubiri rihambaye, ububabare buke nyuma yo kubagwa, no gukira vuba mu buvuzi bwa none bw'indwara z'imitsi.
Kudakora neza kw'imitsi yo mu mitsi (CVI) n'imitsi yo mu gice cyo hasi cy'amaguru bigira ingaruka ku bantu babarirwa muri za miriyoni amagana ku isi, bigatera kuremererwa kw'amaguru, kubyimba, kubabara, dermatitis idakira, ndetse n'ibisebe byo mu mitsi bihora bigaruka. Nubwo kubaga bisanzwe (gufunga no gukuramo imitsi) byahoze ari uburyo bw'ibanze bwo kuvura, kubaga imitsi yo mu mitsi muri iki gihe byahindutse cyane bijya mu buryo bworoshye bwo gukuramo imitsi yo mu mitsi. Muri iki gihe,Kuvura Laser Endovenous (EVLT / EVLA)ihagarariye amahame ya zahabu asabwa n'ubwumvikane mpuzamahanga ku buvuzi bw'indwara z'imitsi—itanga igipimo cyo gufungana kiri hejuru, ibisubizo bidasanzwe ku bwiza, kandi nta na kimwe kigomba gufatirwa mu bitaro.
Kugira ngo bikemure imbogamizi zihoraho za lasers za mbere—nk'ububabare buterwa n'ubushyuhe, n'ingaruka zo kongera gukora—TRIANGEL yatangije igikorwa cyayo cy'ingenzi.Sisitemu ya laser ya V6 ifite uburebure bubiri bw'uburebure (980nm + 1470nm),byakozwe by'umwihariko hamwe n'ikoranabuhanga rya 360° Radial Optical Fiber rigamije kuziba imitsi y'amaraso mu buryo butunganye.
1. Ihuriro rya Chromophore ebyiri: Ubuhanga bwa Biofiziki bwa 980nm + 1470nm
Intsinzi y'ibanze ya EVLT mu buvuzi ishingiye ku kuziba kw'amatara hifashishijwe ikoranabuhanga rigezweho: kohereza ingufu z'urumuri mu ngufu z'ubushyuhe kugira ngo zihindure collagen matrix y'urukuta rw'imitsi (intima na media), bigatera gufungana kw'imitsi burundu no gucika kw'imitsi. Urubuga rwa TRIANGEL V6 rukoresha uburebure bubiri bwuzuzanya cyane kugira ngo rurusheho kunoza uburyo amazi n'amaraso akuramo hemoglobin:
*1470 nm — Uburyo bwo gufata amazi mu buryo bwihariye kugira ngo amazi anyurwe mu buryo bworoshye kandi buciriritse:Amazi ni chromophore yiganje mu rukuta rw'imitsi no mu rukuta rw'imitsi. Uburebure bwa 1470nm bugaragaza ko amazi ashobora kwinjiza amazi inshuro zigera kuri 40 kurusha 980nm, kandi bufite ubunini burenze 810nm cyangwa 1064nm. Ibi bituma ingufu z'ubushyuhe zishyirwa mu gace k'imitsi kagenzurwa neza kandi gacungwa neza mu rukuta rw'imitsi. Kubera iyo mpamvu, ubwinshi bw'uduheri tw'umwuka buragabanuka, uburibwe bw'imitsi yo mu mitsi bukirindwa, kandi uburibwe nyuma yo kubagwa bugabanuka cyane.
*980 nm — Hemoglobin nyinshi ifata amaraso kugira ngo ifashe mu buryo bwihuse kandi itume amaraso adacika:Nubwo 1470nm ivugurura imiterere ya kolajeni y’urukuta rw’imitsi, 980nm ihuye n’urwego rwo hejuru rwo kwinjiza oxyhemoglobin na deoxyhemoglobin. Ibi bitanga uburyo bwo guhita amaraso asohoka mu mitsi, bigafunga imiyoboro y’amaraso kandi bikarinda gusohoka no kuva amaraso mu gihe cyo kubagwa.
★ AGACIRO K'UBUVUZI: IMBARAGA NZIZA NKE, IHUMURE RYINSHI
Ubwumvikane mu buvuzi: Uruvange rw’ubugari bwa 980nm na 1470nm rutuma abaganga babaga bashobora kubaga ku rugero rwo hasi cyane (Joules/cm) ugereranije n’ibice bya 980nm by’uburebure bumwe, bigatuma imitsi ifungana neza ku kigero cya 100% mu gihe bigabanya amanota y’ububabare bw’abarwayi (VAS) ku kigero kirenga 65%.
2. Fiber Optical ya Radial 360°: Ibyuka bizunguruka kimwe
Iterambere rikomeye muri EVLT ya none ni ihinduka riva ku migozi isanzwe idafite ikamba rijya ku migozi yihariye ya Radial Optical Fibers. Imigozi idafite ikamba ikoresha ingufu za laser imbere ku murongo w'ubwoya, ibyo bikaba bikunze gutera ubushyuhe butaringaniye, ubushyuhe bwinshi bugatera ingaruka mbi zo gutobora inkuta z'imitsi. Ibinyuranye n'ibyo, TRIANGEL Radial Optical Fiber ishyiramo micro-prism ya silica refractive ku mpera ya kure:
*Gutanga amakuru nyayo ku bugari bwa 360°:Ingufu zitangwa mu buryo bumwe muri silindiri yuzuye ya dogere 360 igororotse ku rukuta rw'imitsi, bigatuma kolajeni igabanuka mu muyoboro wose w'amaraso uko fibre ikururwa inyuma.
*Gukuraho Itobora no Guhindura Karuboni:Mu kwirinda gukorana neza hagati y’umutwe w’udupira dushyushye cyane n’umutsi uva mu mitsi, imirasire isohora imitsi irinda gutwika inkuta z’imitsi no kwangirika k’uruhu.
*Ingwate yo Guhuza Amaso (<20% by'Ingufu Zitakaza):Imigozi myinshi isanzwe ku isoko itakaza ubushobozi bwo kohereza imiyoboro y’amashanyarazi irenga 20%, bigatuma ingufu zitangwa mu buryo busanzwe ndetse no kongera gukoreshwa mu mitsi mu gihe kirekire. Sisitemu ya TRIANGEL LASEEV yemeza ko SMA905 ihuza neza, bigatuma 100% by’ingufu zisanzwe zigezwa mu rwego rw’ubuvuzi.
3. Porogaramu Isanzwe y'ubuvuzi bw'abarwayi bataha: Kwinjira mu bitaro, Kwita ku barwayi bataha
Uburyo bwa TRIANGEL V6 EVLT bwagenewe gukoreshwa mu buryo bworoshye mu gihe cyo kuvura hakoreshejwe ikinya cyo mu gace k'umubiri. Uburyo busanzwe bwo gukuramo imitsi ya saphenous butwara iminota 25 kugeza kuri 40 gusa kandi bukurikiza uburyo buhamye bwo kuvura bufite ibyiciro bitanu:
• Intambwe ya 1: Gutera Imbunda hifashishijwe Ultrasound:Hashingiwe ku buyobozi bwa ultrasound ya Duplex, uburyo bwo kugera ku ruhu bushyirwa kuri malleolus yo hagati cyangwa munsi y'ivi hakoreshejwe urushinge rwa 18G.
• Intambwe ya 2: Gushyiramo insinga zikoresha amazi zifasha mu gukwirakwiza amazi:Insinga y'amazi ya santimetero 0.035 inyuzwa mu cyuma gifata amazi inyura mu cyuma cya catheter ikagera mu mutsi munini wa saphenous (GSV).
• Intambwe ya 3: Gupima intera ugana kuri SFJ:Uburebure kuva aho umuntu apfundikiye kugeza aho uruziga rwa saphenofemoral (fossa ovalis) rupimwa neza hifashishijwe ultrasound.
• Intambwe ya 4: Gushyira Catheter mu buryo bwinshi hamwe n'aho Radial Fiber iherereye:Agakoresho ko gutanga imitsi gashyirwa kuri cm 1.5–2.0 uvuye aho imitsi ihurira, kandi fibre ya radial ya 360° irashyirwa.
• Intambwe ya 5: Anesthesia ya Tumescent & Laser Ablation:Umuti ukonje wa tumescent winjizwa mu mitsi kugira ngo ukore umusego w’amazi urinda kandi ugongeshe urukuta rw’imitsi kuri fibre. Lazeri ya V6 diode ikoreshwa mu buryo bw’umuraba uhoraho (CW) uko fibre isubizwa inyuma kuri 1-2 mm/sec (ingufu zidasanzwe za Linear Endovenous: 50–70 J/cm).
Uburyo bwo Kuvura Nyuma yo Gukoresha: Udupfundikizo two gukanda cyangwa amasogisi yo mu rwego rwa kabiri yo gukanda ashyirwa ako kanya ku kuguru kwavuwe. Abarwayi barasabwa guhita bahagarara mu nzira mu gihe cy'iminota 20 kandi bagahita basubira mu rugo ako kanya. Gukanda bikomeza iminsi 7 kugeza kuri 14. Isuzuma rya Duplex rikurikiraho ryemeza ko fibrosis y'igice, ijwi rike, kudakanda, no kutagira reflux burundu.
