I-Endovenous Laser

I-Endovenous laser iwukwelapha okuhlasela kancane imithambo ye-varicose engahlaseleki kakhulu kunokukhishwa komthambo ovamile we-saphenous futhi inikeza iziguli ukubukeka okufiseleka kakhudlwana ngenxa yezibazi ezincane. Umgomo wokwelapha ukusebenzisa amandla e-laser ngaphakathi komthambo (i-lumen ye-intravenous) ukucekela phansi umthambo wegazi osuvele unezinkinga.

Inqubo yokwelashwa kwe-laser endovenous ingenziwa emtholampilo, isiguli siphaphame ngokugcwele ngesikhathi senqubo, futhi udokotela uzoqapha isimo semithambo yegazi ngemishini ye-ultrasound.

Udokotela uqala ngokujova umuthi obulala izinzwa wasendaweni ethangeni lesiguli bese evula imbobo ethangeni ethe ukudlula imbobo kaphinifa. Ngemva kwalokho, kufakwa i-fiber optic catheter isuka enxebeni iye emthanjeni. Njengoba ihamba emthanjeni ogulayo, i-fiber ikhipha amandla e-laser ukuze ibangele udonga lwe-vein. Iyancipha, futhi ekugcineni wonke umthambo uyanqamuka, ukuxazulula ngokuphelele inkinga ye-varicose veins.

Ngemva kokuqedwa kokwelashwa, udokotela uzobopha kahle isilonda, futhi isiguli singakwazi ukuhamba njengokujwayelekile futhi siqhubeke nempilo evamile nemisebenzi.

Ngemva kokwelashwa, isiguli singahamba phansi ngemva kokuphumula isikhashana, futhi ukuphila kwaso kwansuku zonke akuthinteki, futhi singakwazi ukuqhubeka nemidlalo ngemva kwamasonto amabili.

1.I-laser engu-980nm nokumuncwa okulinganayo emanzini nasegazini, inikeza ithuluzi eliqinile lokuhlinza lenjongo yonke, kanye nokuphumayo okungu-30/60Watts, umthombo wamandla aphezulu womsebenzi we-endovascular.

2.II-laser engu-1470nmngokumuncwa okuphakeme kakhulu emanzini, kunikeza ithuluzi elinembayo eliphakeme lokunciphisa umonakalo oshisayo ozungezile eduze kwezakhiwo ze-venous. Ngokuvumelana nalokho, kunconywa kakhulu emsebenzini we-endovascular.

I-Laser wavelength 1470, okungenani, imunca kangcono amanzi ne-oxyhemoglobin izikhathi ezingu-40 kune-laser engu-980nm, evumela ukubhujiswa okukhethekile komthambo, ngamandla amancane kanye nokunciphisa imiphumela emibi.

Njenge-laser eqondene namanzi, i-laser ye-TR1470nm iqondise amanzi njenge-chromophore ukuze imunce amandla e-laser. Njengoba ukwakheka komthambo iningi lawo kungamanzi, kucatshangelwa ukuthi i-1470 nm laser wavelength ishisisa kahle amaseli e-endothelial ngengozi ephansi yokulimala okuyisibambiso, okuholela ekuphumeni okuphelele kwemithambo.

Siphinde sinikeze ama-radial fibers.
I-Radial fibre ephuma ku-360° inikezela nge-endovenous ablation eshisayo. Ngakho-ke kungenzeka ukwethula ngobumnene nangokulinganayo amandla e-laser ku-lumen ye-vein futhi uqinisekise ukuvala umthambo ngokusekelwe ekubhujisweni kwe-photothermal (emazingeni okushisa aphakathi kuka-100 no-120 ° C).I-TRIANGEL RADIAL FIBBERifakwe izimpawu zokuphepha zokulawula kahle inqubo yokudonsa emuva.
