Kutchuka kwa Ma Stent a Mtima: Kugwiritsa Ntchito Ukadaulo Wokonza Laser wa Ultrafast

Malinga ndi deta, wodwala m'modzi waku China amagwiritsa ntchito stent ya mtima mphindi iliyonse. Chipangizo chamankhwala chomwe chimawoneka ngati chosawoneka bwinochi chinali chokwera mtengo, chomwe chinkaika mtolo waukulu wazachuma kwa odwala ambiri. Chifukwa cha kukhwima kwa ukadaulo wokonza laser mwachangu kwambiri, mtengo wa stent ya mtima watsika kuchoka pa zikwi makumi ambiri kufika pa mazana a yuan, zomwe zachepetsa kwambiri kupsinjika kwa odwala ndikupatsa odwala ambiri chiyembekezo cha moyo watsopano!

Mfundo Yodulira Laser ya Femtosecond ya Ma Stents

Ma laser a Femtosecond ndi ma laser okhala ndi ma pulse width mu femtosecond (quadrillionth of a second). Pogwiritsa ntchito mphamvu yamagetsi yopangidwa ndi ma femtosecond laser short pulses, ma free electron omwe ali pafupi ndi malo odulira zinthu amatha kuchotsedwa. Izi zimapangitsa kuti zinthu zomwe zili ndi ma positive charges zibwezeretsedwe, ndikuchotsa zinthuzo kudzera mu njira yotchedwa "molecular ablation". Ma stents omwe amakonzedwa mwanjira imeneyi amakhala ndi magawo osalala komanso oyera, opanda ma burrs, kuwonongeka kwa kutentha, kapena kuyaka, ndipo ali ndi ma strut widths olondola kwambiri komanso ofanana.

Ultrafast Laser Chiller Imathandiza Kulamulira Kutentha Koyenera kwa Femtosecond Laser Cutting

Ubwino wa ukadaulo wodula laser mwachangu kwambiri ukuonekera pang'onopang'ono pakugwiritsa ntchito zipangizo zamakono zamankhwala pogwiritsa ntchito micro-nanometer level. choziziritsira cha laser Ndikofunikanso kwambiri pakuwongolera kutentha kolondola kwambiri pakukonza laser mwachangu, ndipo kumatha kuonetsetsa kuti laser imatulutsa bwino mkati mwa nthawi ya picosecond ndi femtosecond. Izi zimathandiza ukadaulo wokonza laser mwachangu kuthana ndi mavuto ambiri okonza zinthu za micro-nano ndikutsegula zida zambiri zamankhwala zogwiritsira ntchito laser mtsogolo.

TEYU Mndandanda wa S&A ultrafast laser chillers uli ndi kulondola kowongolera kutentha mpaka ±0.1℃ , kulamulira kutentha mwanzeru, komanso kuthekera kowongolera kutentha molondola. Dongosolo lake lowongolera kutentha kolondola kwambiri lingathe kuchepetsa kusinthasintha kwa kutentha kwa madzi ndikukhazikitsa mphamvu ya laser kuti liwongolere khalidwe la laser mwachangu kwambiri. Nthawi yomweyo, limaphatikiza ntchito zingapo monga alamu yokakamiza kwambiri, alamu yopitilira muyeso, alamu yotenthetsera kwambiri komanso yotsika, ndi zina zotero. Ndi yosunga mphamvu, yosamalira chilengedwe, yokhazikika, yolimba, ndipo imabwera ndi chithandizo chogulitsa pambuyo pogulitsa, zomwe zimapangitsa kuti ikhale yankho labwino kwambiri loziziritsira m'munda wa micro-nano laser processing ya zipangizo zamakono zamankhwala.
