Endovenous laser mushonga wekurapa mitsipa yeropa isingapindi zvakanyanya asi isingapindi zvakanyanya kupfuura kubviswa kwemitsipa yeropa uye inopa varwere chitarisiko chakanaka nekuda kwemavanga mashoma. Nheyo yekurapa ndeyekushandisa laser simba mukati metsinga (intravenous lumen) kuparadza tsinga yeropa yatove nematambudziko.
Kurapwa ne endovenous laser kunogona kuitwa mukiriniki, murwere anenge akamuka zvizere panguva yekuvhiyiwa, uye chiremba achaongorora mamiriro etsinga dzeropa achishandisa michina ye ultrasound.
Chiremba anotanga abaya mushonga wekurwadziwa pachidya chemurwere uye ogadzira mukana muhudyu wakakura zvishoma pane pinhole. Zvadaro, fiber optic catheter inopinzwa kubva paronda ichipinda mutsinga. Painofamba nemutsinga ine chirwere, fiber iyi inoburitsa simba re laser kuti ibvise madziro etsinga. Inodzikira, uye pakupedzisira tsinga yese inobviswa, zvichigadzirisa zvachose dambudziko retsinga dziri kukuvadzwa.
Kana kurapwa kwapera, chiremba achasunga ronda nemazvo, uye murwere anogona kufamba sezvaagara achiita uye kuramba achiita mabasa ake.
Mushure mekurapwa, murwere anogona kufamba pasi mushure mekuzorora kwenguva pfupi, uye hupenyu hwake hwezuva nezuva hahuna kukanganiswa, uye anogona kutangazve mitambo mushure memavhiki maviri.
1. Laser ye980nm ine kunyudzwa kwakaenzana mumvura neropa, inopa chishandiso chakasimba chekuvhiya, uye pa30/60Watts yekubuda, simba guru rekushanda kwe endovascular.
2.IzvoLaser ye1470nmNekunyorova kwakanyanya mumvura, inopa chishandiso chakanyatsojeka chekuderedza kukuvara kwekupisa kwakakomberedza tsinga. Saka, inokurudzirwa zvikuru pakushanda kwe endovascular.
Kureba kwechiedza cheLaser 1470, kanenge, kunonyudzwa nemvura neoxyhemoglobin ka40 zviri nani kupfuura laser ye980nm, zvichibvumira kuparadzwa kwetsinga, nesimba shoma uye zvichideredza migumisiro yakaipa.
Se laser inoenderana nemvura, laser yeTR1470nm inonanga mvura se chromophore kuti itore simba re laser. Sezvo chimiro chetsinga chiri mvura yakawanda, zvinofungidzirwa kuti 1470 nm laser wavelength inodziya masero endothelial zvinobudirira nenjodzi shoma yekukuvadzwa kwe collateral, zvichikonzera kubviswa kwetsinga zvakanaka.
Tinopawo ma radial fibers.
Radial fiber inoburitsa pa360° inopa endovenous thermal ablation yakakodzera. Saka zvinokwanisika kuisa simba relaser zvinyoro nyoro uye zvakaenzana mu lumen yetsinga uye kuve nechokwadi chekuti tsinga inovharwa zvichibva pakuparadzwa kwe photothermal (patembiricha iri pakati pe100 ne120°C).FAIBHERI YERUDZI RWETRANGELine zviratidzo zvekuchengetedza kuti ikwanise kudzora zvakanyanya maitiro ekudhonza.
