Amagqabantshintshi ngocingo lwentsimbi lwenqanaba lezonyango
Xa kuthelekiswa nesakhiwo semizi-mveliso kwinsimbi engenasici, isinyithi esingenasici sonyango kufuneka sigcine ukuxhathisa kwe-corrosion egqwesileyo emzimbeni womntu, ukunciphisa i-ion zetsimbi, ukutshatyalaliswa, ukuphepha ukubola kwe-intergranular, ukubola koxinzelelo kunye nesiganeko somhlwa wendawo, ukuthintela ukuphuka okubangelwa kwizixhobo ezifakelwe, qinisekisa ukhuseleko lwezixhobo ezifakelwe. 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 yentsimbi eqhelekileyo (idla ngokuhlangabezana neemfuno zomda ophezulu wentsimbi yesiqhelo engenastainless). Umxholo wezinto ezingcolileyo ezifana ne-S kunye ne-P zingaphantsi kunezo eziqhelekileyo zensimbi engenasici, kwaye kucaciswe ngokucacileyo ukuba ubungakanani bezinto ezingenayo i-metallic inclusions kwintsimbi kufuneka zibe ngaphantsi kwe-grade 115 (inkqubo ecocekileyo) 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 nendalo, iipropathi ezilungileyo zoomatshini, kunye nokumelana nokugqwesa kokugqwesa kwamanzi omzimba kunye nokuqhubekeka kakuhle. Insimbi engenasici yezobugqirha isetyenziswa 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 ukufakelwa kotyando olwahlukeneyo, intsimbi yonyango estainless isetyenziselwa ukuvelisa izixhobo ezahlukeneyo zonyango okanye izixhobo, njenge sutures yotyando.
Imigangatho eyahlukeneyo yentsimbi 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.
