Uhlolojikelele lwensimbi yensimbi yezinga lezokwelapha
Uma kuqhathaniswa nesakhiwo sezimboni ngensimbi engagqwali, insimbi engagqwali yezokwelapha idinga ukulondoloza ukumelana nokugqwala okuhle kakhulu emzimbeni womuntu, ukunciphisa i-ion yensimbi, ukubola, ukugwema ukugqwala kwe-intergranular, ukugqwala kwengcindezi kanye nokugqwala kwendawo, ukuvimbela ukuphuka okuvela kumadivayisi afakiwe, qinisekisa ukuthi ukuphepha kwemishini efakelwe.Ngakho-ke, izidingo zayo zokwakheka kwamakhemikhali ziqine kakhulu kunensimbi engagqwali yezimboni.Insimbi engagqwali yezokwelapha efakwe ikakhulukazi emzimbeni womuntu, okuqukethwe kwe-alloy ye-Ni ne-Cr bekuphakeme kunensimbi engagqwali evamile (imvamisa ihlangabezana nezimfuneko zomkhawulo ongaphezulu zensimbi engagqwali evamile).Okuqukethwe kwezakhi ezingcolile ezifana no-S no-P kuphansi kunaleyo yensimbi engagqwali evamile, futhi kubekwe ngokucacile ukuthi ubukhulu bokufakwa okungeyona insimbi ensimbi kufanele kube ngaphansi kwebanga le-115 (uhlelo oluhle) kanye nebanga loku-1 (uhlelo oluqinile. ) ngokulandelana, kuyilapho izinga lensimbi engagqwali evamile yezimboni lingafaki izidingo ezikhethekile zokufakwa.
Insimbi engagqwali yezokwelapha iye yasetshenziswa kabanzi njengempahla yokufakelwa kwezokwelapha kanye nempahla yethuluzi lezokwelapha ngenxa yokuhambisana kwayo okuhle kwezinto eziphilayo, izici ezinhle zokusebenzisa imishini, nokumelana nokugqwala okuhle kakhulu koketshezi lomzimba kanye nokucutshungulwa kahle kwayo.Insimbi engagqwali yezokwelapha isetshenziswa kabanzi ukwenza amathuluzi okulungisa angaphakathi okuhlanganisa nokuphuka okuhlukahlukene, njengazo zonke izinhlobo zenyonga yokwenziwa, idolo, ihlombe, indololwane ehlangene;Kwezamazinyo, isetshenziswa kabanzi kudokotela wamazinyo, ama-orthotics wamazinyo, ukufakwa kwezimpande zamazinyo;Ekuhlinzweni kwenhliziyo, isetshenziselwa i-cardiovascular stent.Ngokungeziwe ekwenzeni izimila ezihlukene zokuhlinzwa, insimbi engagqwali yezokwelapha iphinde isetshenziselwe ukukhiqiza amathuluzi okuhlinza ezokwelapha ahlukahlukene noma amathuluzi, njengama-suture okuhlinzwa.
Insimbi yezinga elihlukile iletha ukusebenza okuhlukile kuzinaliti ze-sutures, kodwa zonke lezi zingahlangabezana nemfuneko ephansi kakhulu yokuhlinzwa okuphephile.
Ishadi elilandelayo libala insimbi engagqwali yezokwelapha okufanele isetshenziswe kakhulu ezinalithini zokuhlinza.
