Overview yezvokurapa giredhi simbi waya
Kuenzaniswa neyakagadzirwa maindasitiri musimbi isina tsvina, Medical Stainless simbi inoda kuchengetedza yakanakisa corrosion kuramba mumuviri wemunhu, kuderedza iyo simbi ions, kunyungudika, kudzivisa intergranular corrosion, kusagadzikana ngura uye yemunharaunda ngura chiitiko, kudzivirira kuputsika kunokonzerwa nemidziyo yakasimwa, kuve nechokwadi chekuchengetedzwa kwemidziyo yakasimwa. Naizvozvo, makemikari ayo ekuumbwa zvinodiwa zvakanyanya kuomarara kupfuura maindasitiri simbi isina tsvina. Simbi yekurapa isina tsvina kunyanya kuiswa mumuviri wemunhu, Ni uye Cr alloy element yemukati yaive yakakwira kupfuura yakajairwa simbi isina tsvina (kazhinji inosangana nepamusoro pepamusoro zvinodiwa zvesimbi isina tsvina). Izvo zviri mukati mezvinhu zvisina kuchena zvakaita seS uye P zvakaderera pane izvo zvakajairwa simbi isina tsvina, uye zvinonyatsotsanangurwa kuti saizi yeasiri-simbi inclusions musimbi inofanira kunge iri pasi pegiredhi 115 (fine system) uye giredhi 1 (coarse system) zvichiteerana, nepo mwero weyakajairwa maindasitiri simbi isina simbi isingaise mberi zvakakosha zvinodiwa pakubatanidzwa.
Simbi yekurapa isimbi yakashandiswa zvakanyanya semidziyo yekurapa uye zvekushandisa zvekurapa nekuda kwekunaka kwayo biocompatibility, yakanaka michina zvivakwa, uye yakanakisa kusakara kwemvura yemuviri 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 mucardiovascular 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.
