Overview yezvokurapa giredhi simbi waya
Kuenzaniswa nechimiro cheindasitiri musimbi isina tsvina, Medical Stainless simbi inoda kuchengetedza yakanakisa corrosion kuramba mumuviri wemunhu, kuderedza maion simbi, kuparara, kudzivirira kuparara kweintergranular, kushushikana kwekuora uye chiitiko chekuora kwenzvimbo, kudzivirira kutyoka kunokonzerwa nemidziyo yakasimwa, simbisa kuchengetedzwa kwemidziyo yakaiswa.Naizvozvo, makemikari ayo ekuumbwa zvinodiwa zvakanyanya kuomarara kupfuura maindasitiri simbi isina tsvina.Simbi yekurapa isina tsvina yakanyatsoiswa mumuviri wemunhu, Ni uye Cr alloy element yemukati yaive yakakwira kupfuura yakajairwa simbi isina tsvina (kazhinji inosangana nepamusoro pepamusoro zvinodiwa zvesimbi isina tsvina).Zviri mukati mezvinhu zvisina kuchena zvakaita seS uye P zvakaderera pane izvo zvesimbi isina tsvina, uye zvinotsanangurwa zvakajeka kuti saizi yeasiri-simbi inclusions musimbi inofanira kunge iri pasi pegiredhi 115 (fine system) uye giredhi 1 (coarse system. ) zvichiteerana, nepo chiyero cheyakajairwa maindasitiri simbi isina simbi isingaise mberi zvakakosha zvinodiwa zvemukati.
Simbi yekurapa isimbi yakashandiswa zvakanyanya semidziyo yekurapa uye zvekushandisa zvekurapa nekuda kweiyo yakanaka biocompatibility, yakanaka michina zvivakwa, uye yakanakisa corrosion kuramba kwemvura dzemuviri uye kuita zvakanaka.Simbi yekurapa isina tsvina inoshandiswa zvakanyanya kugadzira akasiyana-siyana ekugadzira majoini uye kuputsika mukati mekugadzirisa zviridzwa, semhando dzese dzehudyu yakagadzirwa, ibvi, pfudzi, gokora rakabatana;Mumazino, inoshandiswa zvakanyanya mumazino emazino, mazino orthotics, mazino midzi kudyara;Mukuvhiyiwa kwemoyo, inoshandiswa pamwoyo stent.Pamusoro pekugadzira zvakasiyana-siyana zvekuvhiya, simbi isina tsvina yekurapa inoshandiswawo kugadzira zvakasiyana-siyana zvekurapa zvekuvhiya zviridzwa kana maturusi, senge sutures yekuvhiya.
Yakasiyana giredhi simbi inounza kwakasiyana mashandiro pane sutures tsono, asi zvese izvi zvinogona kusangana nechakaderera chinodiwa chekuvhiya kwakachengeteka.
Inotevera chati inoratidza simbi yekurapa isina tsvina iyo inonyanya kushandiswa mukuvhiya sutures tsono.
