E ʻino paha nā lau nitinol?

Nā pepa nitinol he kūpaʻa loa i ka ʻino. ʻO kēia ma muli o ka hiki ʻana o ka titanium, ka mea i hoʻokumu i kahi papa oxide pale ma ka ʻili, e hoʻonui ana i kona kūpaʻa corrosion. Hoʻohana kēia waiwai iā Nitinol i kūpono no ka hoʻohana ʻana i nā kaiapuni like ʻole, me nā noi lāʻau lapaʻau a me ke kai, kahi e koʻikoʻi ai ka pale ʻana i ka corrosion. Eia nō naʻe, ʻoiai ʻoi aku ka kūpaʻa ʻana o Nitinol i ka corrosion i hoʻohālikelike ʻia me nā mea ʻē aʻe he nui, ʻaʻole ia he pale. ʻO ka loaʻa ʻana i nā wahi ʻino a i ʻole kekahi mau kemika hiki ke alakaʻi i ka pala. Hiki i ka mālama mau a me nā kūlana hoʻohana kūpono ke kōkua i ka hoʻēmi ʻana i kēia pilikia.

He aha nā ʻano o nā Pepa Alloy Nitinol Thin?

ʻO Nitinol, kahi hui o ka nickel a me ka titanium, kū i waho ma muli o kāna mau waiwai kupaianaha:

1. Hoʻomanaʻo ʻano: Hiki ke hoʻi ka Nitinol i kona ʻano kumu ma hope o ka hoʻoheheʻe ʻia ʻana i ka wā i wela ai ma luna o kekahi mahana.
2. Superelasticity: Hiki iā ia ke hoʻololi nui a hoʻihoʻi hou i kona ʻano kumu me ka ʻole o ka pōʻino mau ke wehe ʻia ke koʻikoʻi.
3. ʻO ka biocompatibility: He kūpono loa ia me nā ʻiʻo kanaka, no laila kūpono ia no nā noi lapaʻau.
4. Kahi Kuʻuna Corrosion: ʻOiai ke kūpaʻa maʻamau i ka corrosion, hiki ke ʻokoʻa nā kikoʻī ma muli o ke kaiapuni a me nā kūlana.

Nānā Kū'ē Kū'ē

ʻO ke kūʻē ʻana o Nitinol i ka corrosion kekahi o kāna mau pōmaikaʻi nui, ʻoi loa i nā noi biomedical a me nā ʻoihana. Eia naʻe, hiki ke hilinaʻi ʻia ka pae o ke kū'ē ʻana i kekahi mau kumu:

• Maikaʻi Nickel: ʻO ka loaʻa ʻana o ka nickel, ʻoiai he pōmaikaʻi no ka nui o nā waiwai o ka nitinol, hiki iā ia ke maʻalahi i ka ʻino ma lalo o kekahi mau kūlana.
• Nā Hana Hoʻohui: Hiki ke hoʻoikaika i ka pale ʻana i ka corrosion i ka hoʻoliʻiliʻi, ka uhi ʻana, a me nā lāʻau lapaʻau ʻē aʻe.
• Nā kumu hana: Hiki i ka ʻike ʻana i ka paʻakai, acidic, a i ʻole ka alkaline ka hopena i ka nui o ka corrosion.

Pehea ka lōʻihi o ka lahilahi Nā Pepa Nitinol hope?

Hiki ke ʻokoʻa ke ola o nā ʻāpana nitinol lahilahi ma muli o kā lākou noi a me ke kaiapuni i hoʻohana ʻia ai.

Nā mea e pili ana i ka lōʻihi o ke ola

1. noi: I nā lāʻau lapaʻau e like me nā stents, hiki ke koʻikoʻi ka lōʻihi o ka nitinol. Hiki ke paʻakikī ke kaiapuni o ke kino ma muli o ka ʻike mau ʻana i nā wai o ke kino.
2. Nā Kūlana Aʻe: Hiki i nā noi ʻenehana ke hōʻike i ka nitinol i nā kemika koʻikoʻi, nā mahana, a me nā koʻikoʻi mechanical.
3. Mālama a me ka mālama: Hiki i ka mālama mau ʻana a me ka lawelawe ʻana kūpono ke hoʻolōʻihi i ke ola o nā lau nitinol.

Nānā Hiʻohiʻona a me ka Noʻonoʻo

Hōʻike ka noiʻi e hiki ke hana maikaʻi ka nitinol no nā makahiki he nui, ʻoi aku ka nui o ka hoʻohana ʻana i nā lāʻau lapaʻau kūpono. No ka laʻana, ua hōʻike ʻia nā stent nitinol pae lapaʻau i ka lōʻihi ma mua o hoʻokahi mau makahiki me ka ʻole o ka hōʻino nui ʻana.

Hiki ke hana ʻia a hana maʻalahi paha nā lau Nitinol?

ʻO nā waiwai kūʻokoʻa o Nitinol ke kau nei i nā pilikia a me nā manawa kūpono i ka mīkini a me ka hana ʻana.

Nā Luʻi Mīkini

1. Superelasticity: ʻO ka hiki ke hoʻi i kona ʻano kumu i paʻakikī i nā kaʻina hana maʻamau.
2. Mea Paahana: Hoʻohana nui ka Nitinol i nā mea ʻoki ʻoki, e koi ana i nā mea hana kūikawā a me nā ʻenehana.
3. ʻIke wela: Hiki i nā wela kiʻekiʻe ke hoʻololi i nā waiwai o ka mea, pono e mālama pono i ke kaʻina hana.

Nā Hana Hana Hana

Hoʻohana pinepine ʻia nā ʻenehana holomua e like me ka ʻoki ʻana i ka laser, ka ʻoki ʻana i ka wai, a me ka mīkini hoʻolele uila (EDM) e hana i ka nitinol. Kōkua kēia mau ʻano hana i ka loaʻa ʻana o ka pololei me ka ʻole o ka hoʻohaumia ʻana i nā waiwai o ka mea.

He lahilahi Nā Pepa Nitinol Palekana no ka Hoʻohana Lapaʻau?

ʻO ka biocompatibility o Nitinol ka mea i makemake nui ʻia i ka lāʻau lapaʻau, akā ʻoi mau ka hopohopo palekana.

Biocompatibility a me ka palekana

1. Hoʻokuʻu Nikela: ʻOiai ʻo ka nickel kekahi mea o ka nitinol, ʻo ka hoʻokumu ʻia ʻana o kahi papa oxide paʻa e hōʻemi i ka hoʻokuʻu ʻana i ka nickel, e palekana ai no ka hoʻohana ʻana i ka lāʻau lapaʻau.
2. ʻAe ʻApono: Loaʻa nā mea lapaʻau Nitinol i ka hoʻāʻo a me ka ʻae ʻia e nā kino hoʻoponopono e like me ka FDA e hōʻoia i ka palekana a me ka pono.
3. Hoʻohana lāʻau lapaʻau: Ua hoʻohana palekana ʻia ʻo Nitinol i nā mea lapaʻau he nui, me nā stents, nā uea alakaʻi, a me nā mea hana orthodontic.

Nā noi honua maoli

ʻO ka hoʻohana maikaʻi ʻana o ka nitinol i nā noi lapaʻau like ʻole e hōʻike ana i kona palekana a me ka pono. No ka laʻana, hoʻohana nui ʻia nā stents nitinol i ka mālama cardiovascular, e hōʻike ana i ka hana maikaʻi loa a me nā hopena hoʻomanawanui.

Panina

I ka hopena, hāʻawi nā ʻāpana nitinol, ʻoi aku ka lahilahi o ka nitinol alloy sheets, i nā waiwai kupaianaha e kūpono ai no nā ʻano noi. ʻO kā lākou pale ʻana i ka corrosion, ka lōʻihi, ka machinability, a me ka palekana i nā noi lapaʻau i kākau maikaʻi ʻia a ʻike nui ʻia. Ma ka hoʻomaopopo ʻana i nā nuances o ke ʻano o ka nitinol a me ka mālama pono ʻana, hiki i nā ʻoihana ke hoʻohana i kāna mau hiʻohiʻona kūʻokoʻa i ko lākou pono.
