Mabhenefiti etitanium senzira yekuisa simbi mumabhonzo

Zvakanakira zvetitanium sezvinhu zve orthopedic implant zvinonyanya kuratidzwa muzvinhu zvinotevera:

1, Kuenderana kwehupenyu:

Titanium ine hukama hwakanaka nenyama yemunhu, haina simba rakawanda rekuita nemuviri wemunhu, haina chepfu uye haina simba remagineti, uye haina chepfu mumuviri wemunhu.

Kuenderana kwakanaka uku kunoita kuti titanium implants ivepo mumuviri wemunhu kwenguva yakareba pasina kukonzera kusawirirana kuri pachena.

2, Zvimiro zveMichina:

Titanium ine hunhu hwesimba rakakwirira uye modulus yakaderera inonamira, iyo isingangosviki chete zvinodiwa zvemakanika, asiwo iri pedyo nemodulus inonamira yemapfupa emunhu chaiwo.

Hunhu uhwu hwemuchina hunobatsira kuderedza simba rekudzivirira kushushikana uye hunobatsira kukura nekupora kwemapfupa evanhu.

Modulus ye elastic yetitanium alloyyakaderera. Semuenzaniso, elastic modulus ye pure titanium i108500MPa, iri pedyo nemapfupa emuviri wemunhu, ayo ari

inobatsira pakugadzika kwemapfupa uye kuderedza simba rekudzivirira mapfupa pazvishandiso zvemuviri.

3, Kuramba ngura:

Titanium alloy chinhu chisina simba mumuviri uye chinodzivirira ngura zvakanaka munzvimbo yemuviri wemunhu.

Kusabatwa nengura uku kunoita kuti zvinhu zvinoiswa mu titanium alloy mumuviri wemunhu zvigare kwenguva refu uye hazvizosvibisi nharaunda yemuviri wemunhu nekuda kwengura.

4, Zvishoma:

Kuwanda kwe titanium alloy kwakaderera, 57% chete yesimbi isina ngura.

Mushure mekuiswa mumuviri wemunhu, zvinogona kuderedza mutoro wemuviri wemunhu zvakanyanya, izvo zvinonyanya kukosha kune varwere vanoda kupfeka ma implants kwenguva yakareba.

5, Kwete-rinobva:

Chiumbwa chetitanium hachina simba remagineti uye hachikanganisike neminda yemagetsi nemadutu, izvo zvinobatsira kuchengetedzeka kwemuviri wemunhu mushure mekuiswa.

6, Kubatanidzwa kwakanaka kwemapfupa:

Rutivi rwe oxide rwakagadzirwa nenzira yechisikigo pamusoro pe titanium alloy runobatsira pakuumbwa kwemapfupa uye runoita kuti mapfupa arambe akabatana zvakanaka uye runoita kuti pave nekunamatirana pakati pechinhu chakaiswa mudumbu nepfupa.

Tichakupa zvinhu zviviri zvakakodzera zve titanium alloy:

Mashandiro eTC4:

Chiumbwa cheTC4 chine vanadium 6% uye 4%. Ndiyo chiumbwa che α+β chinoshandiswa zvakanyanya chine simba guru. Chine simba repakati uye plasticity yakakodzera. Chinoshandiswa zvakanyanya mundege, ndege, ma implants evanhu (mapfupa ekugadzira, majoini ehudyu evanhu nezvimwe zvinhu zvipenyu, 80% yazvo parizvino zvinoshandisa chiumbwa ichi), nezvimwewo. Zvigadzirwa zvayo zvikuru ma bars nema cakes.

Ti6AL7Nbmashandiro

Chidimbu cheTi6AL7Nb chine 6% AL uye 7% Nb. Ndicho chinhu chemhando yepamusoro chetitanium alloy chakagadzirwa uye chakashandiswa pazvidyarwa zvevanhu muSwitzerland. Chinodzivirira zvikanganiso zvezvimwe zvidyarwa uye chinotamba zviri nani setitanium alloy mu ergonomics. Ndicho chinhu chemhando yepamusoro chezvidyarwa zvevanhu mune ramangwana. Chichashandiswa zvakanyanya muzvidyarwa zvemazino zvetitanium, zvidyarwa zvemapfupa evanhu, nezvimwewo.

Muchidimbu, titanium sechinhu chinoiswa mumapfupa chine zvakanakira zvekushanda zvakanaka, hunhu hwemakanika, kuramba ngura, huremu hushoma, kusashandisa simba remagetsi uye kubatana kwakanaka kwemapfupa, izvo zvinoita kuti titanium ive sarudzo yakakodzera yezvinhu zvinoiswa mumapfupa.
