Laser Yopanda Mphamvu

Endovenous laser ndi mankhwala ochepetsa ululu omwe sawononga mitsempha ya varicose yomwe siwononga kwambiri kuposa njira yachikhalidwe yochotsera mitsempha ya saphenous ndipo imapatsa odwala mawonekedwe abwino kwambiri chifukwa cha zipsera zochepa. Mfundo yaikulu ya chithandizo ndikugwiritsa ntchito mphamvu ya laser mkati mwa mitsempha (intravenous lumen) kuti muwononge mitsempha yamagazi yomwe yayamba kale kuvutika.

Njira yothandizira pogwiritsa ntchito laser ya endovenous ikhoza kuchitidwa kuchipatala, wodwalayo amakhala maso mokwanira panthawi ya opaleshoniyi, ndipo dokotalayo adzayang'anira momwe mitsempha yamagazi ilili pogwiritsa ntchito zida za ultrasound.

Dokotalayo amayamba ndi jakisoni wa mankhwala oletsa ululu m'ntchafu ya wodwalayo ndipo amapanga mpata m'ntchafu womwe ndi waukulu pang'ono kuposa dzenje la pinbo. Kenako, catheter ya fiber optic imayikidwa kuchokera pabala kupita m'mitsempha. Pamene ikuyenda kudzera m'mitsempha yodwala, ulusiwo umatulutsa mphamvu ya laser kuti iwononge khoma la mtsempha. Umachepa, ndipo pamapeto pake mtsempha wonse umachotsedwa, zomwe zimathetsa vuto la mitsempha ya varicose.

Pambuyo poti chithandizo chatha, dokotala adzamanga bala bwino, ndipo wodwalayo akhoza kuyenda monga mwachizolowezi ndikupitiriza ndi moyo ndi zochita zake zachizolowezi.

Pambuyo pa chithandizo, wodwalayo amatha kuyenda pansi atapuma pang'ono, ndipo moyo wake watsiku ndi tsiku sungakhudzidwe kwenikweni, ndipo amatha kuyambiranso masewera patatha milungu iwiri.

1. Laser ya 980nm yokhala ndi kuyamwa kofanana m'madzi ndi m'magazi, imapereka chida cholimba chochitira opaleshoni, komanso pa 30/60Watts ya kutulutsa, ndi gwero lamphamvu kwambiri la ntchito ya endovascular.

2. TheLaser ya 1470nmPopeza imayamwa kwambiri m'madzi, imapereka chida cholondola kwambiri chochepetsera kuwonongeka kwa kutentha kozungulira mitsempha yamagazi. Chifukwa chake, imalimbikitsidwa kwambiri pa ntchito ya endovascular.

Kutalika kwa mafunde a laser 1470, osachepera, kumayamwa bwino nthawi 40 ndi madzi ndi oxyhemoglobin kuposa laser ya 980nm, zomwe zimapangitsa kuti mitsempha iwonongeke mosankha, ndi mphamvu zochepa komanso kuchepetsa zotsatirapo zake.

Monga laser yogwiritsidwa ntchito m'madzi, laser ya TR1470nm imayang'ana madzi ngati chromophore kuti itenge mphamvu ya laser. Popeza kapangidwe ka mitsempha kamakhala madzi ambiri, akuti kutalika kwa mafunde a laser a 1470 nm kumatenthetsa bwino maselo a endothelial ndi chiopsezo chochepa cha kuwonongeka kwa collateral, zomwe zimapangitsa kuti mitsempha ikhale yabwino kwambiri.

Timaperekanso ulusi wa radial.
Ulusi wozungulira womwe umatulutsa pa 360° umapereka mpweya wabwino kwambiri wotentha mkati mwa endovenous. Chifukwa chake, n'zotheka kuyika mphamvu ya laser pang'onopang'ono komanso mofanana mu lumen ya mtsempha ndikuonetsetsa kuti mtsempha ukutsekedwa kutengera kuwonongeka kwa photothermal (pa kutentha pakati pa 100 ndi 120°C).CHIKWANGWANI CHA TRIANGEL RADIALIli ndi zizindikiro zachitetezo kuti ilamulire bwino njira yobwerera m'mbuyo.
