Amagqabantshintshi ngocingo lwentsimbi lwenqanaba lezonyango
Xa kuthelekiswa nolwakhiwo lwemizi-mveliso kwinsimbi engenasici, intsimbi yezonyango idinga ukugcina ukuxhathisa okugqwesileyo emzimbeni womntu, ukunciphisa i-ion zetsimbi, ukunyibilika, ukuphepha ukubola kwe-intergranular, i-corrosion yoxinzelelo kunye nemeko ye-corrosion yendawo, ukuthintela ukwaphuka okubangelwa kwizixhobo ezifakelweyo, 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 yentsimbi eqhelekileyo (idla ngokuhlangabezana neemfuno zomda ophezulu wentsimbi yesiqhelo engenastainless). Umxholo wezinto ezingcolileyo ezifana ne-S kunye ne-P ziphantsi kunezinsimbi eziqhelekileyo ezingenasici, kwaye zichazwe ngokucacileyo ukuba ubungakanani bezinto ezingenayo isinyithi kwintsimbi kufuneka zibe ngaphantsi kwe-grade 115 (i-fine system) kunye ne-grade 1 (inkqubo enqabileyo. ) ngokulandelanayo, ngelixa umgangatho we-industrial steel stainless steel 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.
