Amagqabantshintshi ngocingo lwentsimbi lwenqanaba lezonyango
Xa kuthelekiswa nolwakhiwo lweshishini kwintsimbi engenasici, intsimbi yezonyango idinga ukugcina ukuxhathisa okugqwesileyo emzimbeni womntu, ukunciphisa i-ion zetsimbi, ukutshatyalaliswa, ukuphepha ukubola kwe-intergranular, i-corrosion ye-stress kunye ne-corrosion phenomenon yendawo, ukukhusela ukuphuka okubangelwa kwizixhobo ezifakelwe, qinisekisa ukuba ukhuseleko lwezixhobo ezifakelweyo.Ke ngoko, iimfuno zayo zokwakheka kweekhemikhali zingqongqo ngakumbi kunesinyithi esingenasici kwishishini.Intsimbi yezonyango efakwe ngokukodwa emzimbeni womntu, i-Ni kunye ne-Cr i-alloy content content yayiphezulu kunentsimbi yesiqhelo engenasici (idla ngokuhlangabezana neemfuno zomda ophezulu wentsimbi yesiqhelo engenastainless).Umxholo wezinto ezingcolileyo ezifana ne-S kunye ne-P ziphantsi kunezinsimbi eziqhelekileyo zetsimbi, kwaye kucaciswe ngokucacileyo ukuba ubungakanani bezinto ezingenayo isinyithi kwintsimbi kufuneka zibe ngaphantsi kwe-grade 115 (inkqubo efanelekileyo) kunye nebakala 1 (inkqubo enqabileyo. ) ngokulandelanayo, ngelixa umgangatho we-industrial stainless steel stainless awufaki iimfuno ezikhethekileyo zokufakwa.
Intsimbi yezonyango isetyenziswe ngokubanzi njengemathiriyeli yokufakelwa kwezonyango kunye nesixhobo sesixhobo sonyango ngenxa yokuhambelana kwayo kakuhle ne-biocompatibility, iipropathi ezilungileyo zoomatshini, kunye nokumelana nokugqwesa kokugqwesa kolwelo lomzimba kunye nokuqhubekeka kakuhle.Insimbi engenasici yezonyango isetyenziselwa ngokubanzi ukwenza izixhobo ezahlukeneyo zokulungiswa kwangaphakathi kunye nokwaphuka, njengazo zonke iintlobo ze-hip eyenziweyo, idolo, igxalaba, i-elbow joint;Kwi-dentistry, isetyenziswa ngokubanzi kwi-dentistry yamazinyo, i-orthotics yamazinyo, ukufakelwa kweengcambu zamazinyo;Kutyando lwentliziyo, isetyenziswa kwi-cardiovascular stent.Ukongeza ekwenzeni iintlobo zofakelo lotyando, intsimbi yonyango estainless isetyenziselwa ukuvelisa izixhobo ezahlukeneyo zonyango okanye izixhobo, njenge sutures yotyando.
Intsimbi yebakala eyahlukileyo izisa ukusebenza okwahlukileyo kwiinaliti ze-sutures, kodwa zonke ezi zinokuhlangabezana neyona mfuno iphantsi yotyando olukhuselekileyo.
Itshathi elandelayo idwelisa intsimbi yonyango engatyiwayo nekufuneka isetyenziswe ikakhulu kwiinaliti zotyando.
