Kōkua ʻo Femtosecond laser i ka hoʻomohala wikiwiki ʻana o ka hana stent lapaʻau pololei

I kēia mau makahiki i hala iho nei, ua hoʻohana nui ʻia ka hana laser i ka hana ʻana i nā mea lapaʻau, e like me ka pololeimea ʻoki laser, nā mea hana hoʻoheheʻe laser lapaʻau, nā mea hoʻoheheʻe laser, nā mea hōʻailona laser, a me nā mea'ē aʻe.

Noho ʻo Fiber lasers i kahi kūlana koʻikoʻi i ka ʻoihana hana lāʻau lapaʻau ma muli o ko lākou kumukūʻai haʻahaʻa, ka mana scalable a me nā pono ʻē aʻe.ʻO nā mea laser e like me picosecond a me femtosecond he mau mea maikaʻi loa ma ke ʻano o ka ʻoki ʻana i ka maikaʻi, akā ua liʻiliʻi ko lākou mākeke no ka manawa lōʻihi.

I kēia mau makahiki i hala iho nei, me ka piʻi nui ʻana o nā pono o nā lāʻau lapaʻau kūpono no ka ʻoki ʻana i ka maikaʻi, ua wikiwiki ka noiʻi ʻana o ka mea nui a me ka hoʻomohala ʻana i nā mea lapaʻau laser, a ʻo nā lasers ultrafast e like me femtoseconds e lilo i laser i makemake ʻia i nā hiʻohiʻona noiʻi hana lāʻau lapaʻau, a me kēia mau lasers. ke komo mau nei i nā ʻano lāʻau lapaʻau.

ʻO nā lāʻau lapaʻau i hana ʻia me ka hoʻohana ʻana i nā lasers femtosecond, neurological a me cardiovascular stents ka mea maʻamau.Hiki i ka laser femtosecond ke hana pololei i nā huahana burrless, micron-scale stent ma nā huahana lāʻau lapaʻau, he mea koʻikoʻi ia e pale aku ai i nā hopena kūlohelohe / hōʻole ke hoʻokomo ʻia i loko o ke kino kanaka.He nui nā stents lāʻau lapaʻau i hana ʻia me ka nickel-titanium alloy, ʻo ka hoʻohana mua ʻana o ka ʻenehana mechanical e hoʻoponopono i kēia alloy nickel-titanium ʻaʻole maʻalahi, ua lilo ka femtosecond laser i mea pono.

ʻO ka manaʻo o ka "intervention without implantation" he ʻano koʻikoʻi ia i ka hoʻomohala ʻana i ka hoʻomohala ʻana o ka coronary interventional therapy.Hiki ke hoʻokaʻawale ʻia nā stent naʻau i ʻehā mau ʻāpana: ka hoʻomāhuahua ʻana i ka baluna maʻemaʻe, nā stent metala ʻole, nā stents drug-eluting, a me nā stents biodegradable.

ʻAʻole e like me nā stents naʻau ma mua, ʻo nā stents biodegradable he mau scaffolds i hana ʻia me nā mea polymer degradable (e like me ka polylactic acid) hiki ke hoʻoheheʻe ʻia a hoʻomoʻa ʻia e ke kino kanaka i loko o kekahi manawa.Ke hoʻoponopono houʻia nā kīʻaha koko, hoʻohaʻahaʻa pololei ka stent i ka wai a me ke kalapona'okikene i loko o ke kino, i ka hoʻohālikelikeʻana i ka metala kahiko - a me nā stents i uhiʻia i ka lāʻau.Hōʻike nā hōʻike noiʻi e kū nei i ka maikaʻi o nā stents biodegradable, hiki ke hoʻopau i ka mana o ke koena o nā stents ʻole i ka hoʻihoʻi ʻana i ka hana vascular a hōʻemi i ka hopena o nā hanana pōʻino lōʻihi ma hope o PCI.

Me kona mau pono kūʻokoʻa, e lilo nā mea stent degradable i ke ʻano nui i ka hoʻomohala ʻana i ka ʻenehana stent naʻau honua.I ka hana ʻana o kēia mea polymer a me nā mea ʻē aʻe non-metallic, inā ka fiber laser processing, hiki ke hoʻomehana ʻia ka mea a hoʻololi i ka haku melemele, hiki ke hoʻohua i nā mea ʻawaʻawa.Inā makemake ʻoe e hōʻemi i kēia mau hopena wela a hōʻoia i ka maikaʻi o ka hopena o ka hoʻoili ʻana, ʻo ka koho mua ʻo ia nā mea laser femtosecond.

ʻO kekahi o nā pōmaikaʻi nui o ka hoʻohana ʻana i nā pulses femtosecond (10^-15s) i hoʻohālikelike ʻia me nā nanosecond a i ʻole nā ​​​​pulse picosecond ʻo ia ka hoʻemi ʻana o ka manawa pili ma waena o ka lāʻau a me ka mea hana e like me ka hiki, e hōʻemi ana i ka wahi wela i ka mea hana. e hoemi ana i ka hopena o ka wela nui.No kekahi mau mea lapaʻau, me nā stents, he mea koʻikoʻi kēia i ka hoʻomaikaʻi ʻana i ka biocompatibility o nā mea implant.

Hiki i nā lasers Femtosecond ke hana i nā huahana me ka pololei kiʻekiʻe.ʻO ke anawaena mai ka 2 a 5mm ka lōʻihi mai ka 13 a hiki i ka 33mm.Manaʻo ʻia kahi hāmeʻa laser femtosecond inā makemake ʻoe i nā kikoʻī stent kiʻekiʻe a me nā ʻoki e hōʻemi i ka hopena o ka hoʻololi biopolymer a i ʻole ka hoʻoneʻe metala.Mai ka hiʻohiʻona o ke kaʻina hana stent holoʻokoʻa, ʻoi aku ka maikaʻi o ka laser femtosecond e hōʻemi i nā pono post-processing ma hope o ka ʻoki ʻana i ka stent.

ʻO ka ʻoki laser Femtosecond vs ka hopena ʻoki laser Fiber

ʻO nā holomua hou o ka ʻenehana laser femtosecond ua hoʻokomo i nā mana ʻoi aku ka maikaʻi i ka hoʻoponopono ʻana i nā mea lapaʻau pololei, e hoʻopau ana i nā hopena wela me ka hōʻemi ʻana i ka hana hope.
