Phakathi nenqubo yemizuzu engama-45, kufakwa i-catheter ye-laser emthanjeni onephutha. Lokhu kuvame ukwenziwa ngaphansi kwe-anesthesia yendawo kusetshenziswa isiqondiso se-ultrasound. I-laser ishisa ulwelwesi olungaphakathi komthambo, iwulimaze futhi ibangele ukuthi lunciphe, bese ivala. Uma lokhu sekwenzekile, umthambo ovaliwe awusakwazi ukuthwala igazi, uqede ukuvuvuka kwemithambo ngokulungisa impande yenkinga. Ngenxa yokuthi le mithambo ingaphezulu, ayidingeki ukuze kudluliselwe igazi eliphelelwe umoya-mpilo emuva enhliziyweni. Lo msebenzi uzoqondiswa ngokwemvelo emithanjeni enempilo. Eqinisweni, ngobaumthambo we-varicosengokwencazelo yonakele, empeleni ingaba yingozi empilweni yakho yonke yokujikeleza kwegazi. Nakuba kungeyona ingozi empilweni, kufanele kuxazululwe ngaphambi kokuba kuvele ezinye izinkinga.
Amandla e-laser angu-1470nm amuncwa ngokukhethekile emanzini angaphakathi kweseli odongeni lwemithambo yegazi kanye nasemanzini egazini.
Inqubo yokushisa kwe-photo-thermal engenakuguqulwa ebangelwa amandla e-laser iholela ekuvalekeni okuphelele kwe-umthambo ophathwe kahle.
Izinga eliphansi lamandla elidingekayo kusetshenziswa i-radial laser fiber linciphise kakhulu imiphumela emibi uma kuqhathaniswa ne-bare laser fiber.
IZINZUZO
*Inqubo yangaphakathi ehhovisi yenziwe ngaphansi kwehora
*Akukho ukuhlala esibhedlela
* Ukuphumula okusheshayo ezimpawini
*Akukho ukushaqeka okungathandeki noma ukugqwala okukhulu nokubonakalayo
*Ukululama okusheshayo nobuhlungu obuncane ngemva kwenqubo
