ʻO nā pōmaikaʻi o ka titanium ma ke ʻano he mea implant orthopedic

ʻO nā mea maikaʻi o ka titanium ma ke ʻano he orthopedic implant mea i hōʻike nui ʻia i nā ʻano aʻe:

1、Biocompatibility:

ʻO ka Titanium ka biocompatibility maikaʻi me ka ʻiʻo o ke kanaka, ka liʻiliʻi o ka hopena biological me ke kino o ke kanaka, ʻaʻohe mea ʻawaʻawa a ʻaʻohe magnetika, a ʻaʻohe hopena ʻino i ke kino o ke kanaka.

ʻO kēia biocompatibility maikaʻi e hiki ai i nā implants titanium ke noho i loko o ke kino o ke kanaka no ka manawa lōʻihi me ka ʻole o ka hōʻole ʻana i nā hopena.

2 、ʻAno Mechanical:

Loaʻa i ka Titanium nā hiʻohiʻona o ka ikaika kiʻekiʻe a me ka modulus elastic haʻahaʻa, ʻaʻole i hoʻokō wale i nā koi mechanical, akā pili pū kekahi i ka modulus elastic o ka iwi maoli.

ʻO kēia waiwai mīkini kōkua e hōʻemi i ka hopena pale koʻikoʻi a ʻoi aku ka maikaʻi o ka ulu a me ka ho'ōla ʻana o nā iwi kanaka.

ʻO ka modulus elastic ohuila titaniumhe haahaa. No ka laʻana, ʻo ka modulus elastic o ka titanium maʻemaʻe ʻo 108500MPa, kahi kokoke i ka iwi maoli o ke kino kanaka, ʻo ia ka

kūpono i ka hoʻonohonoho iwi a hoʻemi i ka hopena pale koʻikoʻi o nā iwi ma nā implants.

3 、 Ke kū'ē i ka corrosion:

ʻO ka Titanium alloy kahi mea inert biologically me ka pale ʻana i ka corrosion maikaʻi i ke kaiapuni physiological o ke kino kanaka.

ʻO kēia kūpaʻa corrosion e hōʻoia i ka lōʻihi o ka paʻa ʻana o ka titanium alloy implants i loko o ke kino kanaka a ʻaʻole ia e hoʻohaumia i ke ʻano physiological o ke kino kanaka ma muli o ka corrosion.

4. Māmā:

He haʻahaʻa haʻahaʻa ka nui o ka alloy titanium, ʻo 57% wale nō o ke kila kila.

Ma hope o ka hoʻokomo ʻia ʻana i loko o ke kino kanaka, hiki iā ia ke hōʻemi nui i ka ukana ma ke kino o ke kanaka, he mea nui loa ia no nā poʻe maʻi e pono e hoʻokomo i nā implants no ka manawa lōʻihi.

5. ʻAʻole magnetic:

ʻAʻole pili ka Titanium alloy a ʻaʻole i hoʻopilikia ʻia e nā māla electromagnetic a me nā hekili, kahi mea e pono ai ka palekana o ke kino kanaka ma hope o ke kanu ʻana.

6. Hoʻohui iwi maikaʻi:

Hāʻawi ka papa oxide i hana maoli ʻia ma ka ʻili o ka titanium alloy i ka hiki ʻana o ka hoʻohui iwi a hoʻomaikaʻi i ka pili ʻana ma waena o ka implant a me ka iwi.

Ke hoʻolauna nei i ʻelua mau mea hoʻoheheʻe titanium kūpono loa:

Hana TC4:

Aia ka TC4 alloy i ka 6% a me 4% vanadium. ʻO ia ka mea i hoʻohana nui ʻia ʻo α+β type alloy me ka puka nui loa. Loaʻa iā ia ka ikaika waena a me ka plasticity kūpono. Hoʻohana nui ʻia ia i ka aerospace, aviation, implants kanaka (iwi artificial, hui pūhaka kanaka a me nā biomaterials ʻē aʻe, ʻo 80% ka mea e hoʻohana nei i kēia alloy), etc. ʻO kāna mau huahana nui he mau pahu a me nā keke.

Ti6AL7Nbhoʻokō

Loaʻa iā Ti6AL7Nb alloy he 6% AL a me 7% Nb. ʻO ia ka mea ʻoi loa o ka titanium alloy material i hoʻomohala ʻia a hoʻohana ʻia i nā implants kanaka ma Switzerland. Hōʻalo ia i nā hemahema o nā ʻāpana implant ʻē aʻe a ʻoi aku ka maikaʻi o ka hana o ka titanium alloy i nā ergonomics. ʻO ia ka mea i hoʻopaʻa ʻia i ke kanaka i ka wā e hiki mai ana. E hoʻohana nui ʻia ia i nā implants dental titanium, implants iwi iwi, etc.

I ka hōʻuluʻulu ʻana, ʻo ka titanium ma ke ʻano he orthopedic implant mea i loaʻa i nā pono o ka biocompatibility maikaʻi loa, nā waiwai mechanical, ka pale ʻana i ka corrosion, ke kaumaha māmā, ka non-magneticity a me ka hoʻohui iwi maikaʻi, e hana ai ka titanium i kahi koho maikaʻi loa no nā mea implant orthopedic.
