I-Laser Endovenous

I-laser ye-Endovenous iyindlela yokwelapha engenamandla kakhulu yemithambo ye-varicose engangenisi kakhulu kunokukhishwa kwemithambo ye-saphenous yendabuko futhi inikeza iziguli ukubukeka okufiselekayo ngenxa yezibazi ezincane. Isimiso sokwelapha ukusebenzisa amandla e-laser ngaphakathi kwemithambo (i-intravenous lumen) ukubhubhisa umthambo wegazi osuvele unenkinga.

Inqubo yokwelashwa nge-laser endovenous ingenziwa emtholampilo, isiguli sivukile ngokuphelele ngesikhathi senqubo, futhi udokotela uzoqapha isimo semithambo yegazi ngemishini ye-ultrasound.

Udokotela uqala ngokufaka umuthi wokubulala izinzwa wendawo ethangeni lesiguli bese edala imbobo ethangeni elikhulu kancane kunembobo yephini. Ngemuva kwalokho, kufakwa i-catheter ye-fiber optic esuka enxebeni iye emthanjeni. Njengoba ihamba emthanjeni onesifo, i-fiber ikhipha amandla e-laser ukuze ibulale udonga lwemithambo. Iyancipha, futhi ekugcineni yonke imithambo iyasuswa, kuxazululwe ngokuphelele inkinga yemithambo ekhuphukile.

Ngemva kokuba ukwelashwa sekuqediwe, udokotela uzolibopha kahle inxeba, futhi isiguli singahamba njengokujwayelekile futhi siqhubeke nempilo nemisebenzi evamile.

Ngemva kokwelashwa, isiguli singahamba phansi ngemva kokuphumula isikhashana, futhi impilo yaso yansuku zonke ayithinteki, futhi singaphinde siqale ezemidlalo ngemva kwamasonto amabili.

1. I-laser engu-980nm emunca ngokulinganayo emanzini nasegazini, inikeza ithuluzi lokuhlinza eliqinile elisebenza kuzo zonke izinjongo, futhi ngama-Watts angu-30/60 okukhipha, umthombo wamandla aphezulu womsebenzi we-endovascular.

2. II-laser engu-1470nmngokumuncwa okuphezulu kakhulu emanzini, kunikeza ithuluzi elinembile kakhulu lokunciphisa umonakalo wokushisa ohambisana nezakhiwo zemithambo yegazi. Ngakho-ke, kunconywa kakhulu emsebenzini we-endovascular.

Ubude be-laser obungu-1470, okungenani, bumuncwa kangcono ngokuphindwe ka-40 ngamanzi kanye ne-oxyhemoglobin kune-laser engu-980nm, okuvumela ukubhujiswa okukhethiwe komthambo, ngamandla amancane kanye nemiphumela emibi encishisiwe.

Njenge-laser eqondene namanzi, i-laser ye-TR1470nm ihlose amanzi njenge-chromophore ukuze imunce amandla e-laser. Njengoba isakhiwo semithambo ikakhulu singamanzi, kucatshangwa ukuthi ubude be-laser obungu-1470 nm bufudumeza kahle amaseli e-endothelial ngengozi ephansi yokulimala okuhlangene, okuholela ekususweni kwemithambo okungcono kakhulu.

Siphinde sinikeze imicu ye-radial.
I-radial fiber ekhipha ku-360° inikeza i-endovenous thermal ablation efanelekile. Ngakho-ke kungenzeka ukufaka amandla e-laser ngobumnene nangokulinganayo ku-lumen yomthambo nokuqinisekisa ukuvalwa komthambo ngokusekelwe ekubhujisweni kwe-photothermal (emazingeni okushisa aphakathi kuka-100 no-120°C).I-Thringe Radial Fiberifakwe izimpawu zokuphepha zokulawula kahle inqubo yokudonsa.
