Poyerekeza ndi kapangidwe mafakitale zitsulo zosapanga dzimbiri, Medical zitsulo zosapanga dzimbiri ayenera kukhalabe bwino dzimbiri kukana mu thupi la munthu, kuchepetsa ayoni zitsulo, kuvunda, kupewa dzimbiri intergranular, nkhawa dzimbiri ndi m'dera dzimbiri chodabwitsa, kupewa fracture chifukwa cha zipangizo anaikamo, kuonetsetsa chitetezo cha zida zoyikidwa. Choncho, mankhwala ake zikuchokera zofunika ndi okhwima kuposa mafakitale zosapanga dzimbiri zitsulo. Chitsulo chosapanga dzimbiri chamankhwala chomwe chimayikidwa m'thupi la munthu, zinthu za Ni ndi Cr alloy zinali zapamwamba kuposa zitsulo zosapanga dzimbiri (nthawi zambiri zimakwaniritsa zofunikira zachitsulo chosapanga dzimbiri). Zomwe zili muzinthu zonyansa monga S ndi P ndizochepa kusiyana ndi zitsulo zosapanga dzimbiri wamba, ndipo zikufotokozedwa momveka bwino kuti kukula kwazitsulo zopanda zitsulo muzitsulo ziyenera kukhala zosachepera kalasi ya 115 (fine system) ndi grade 1 (coarse system). ) motero, pamene muyezo wamba mafakitale zosapanga dzimbiri zitsulo sizimaika patsogolo zofunika inclusions.

kalasi-zitsulo-waya-2Chitsulo chosapanga dzimbiri chamankhwala chakhala chikugwiritsidwa ntchito kwambiri ngati zida zachipatala komanso zida zamankhwala chifukwa cha kuyanjana kwake, makina abwino amakina, komanso kukana dzimbiri kwamadzi am'thupi komanso kusinthika kwabwino. Chitsulo chosapanga dzimbiri chamankhwala chimagwiritsidwa ntchito kwambiri popanga zida zosiyanasiyana zolumikizirana komanso zothyoka mkati, monga mitundu yonse ya chiuno chochita kupanga, bondo, phewa, kulumikizana kwa chigongono; Mu mano, chimagwiritsidwa ntchito mu mano mano, mano orthotics, mano mizu implantation; Mu opaleshoni ya mtima, amagwiritsidwa ntchito pamtima stent. Kuphatikiza pa kupanga ma implants osiyanasiyana opangira opaleshoni, chitsulo chosapanga dzimbiri chamankhwala chimagwiritsidwanso ntchito popanga zida kapena zida zopangira opaleshoni, monga ma sutures opangira opaleshoni.

Chitsulo chosiyana siyana chimabweretsa ntchito zosiyanasiyana pa singano za sutures, koma zonsezi zimatha kukwaniritsa zofunikira zochepa kwambiri za opaleshoni yotetezeka.

Tchati chotsatirachi chikuwonetsa chitsulo chosapanga dzimbiri chamankhwala chomwe chimagwiritsidwa ntchito kwambiri popanga singano zopangira opaleshoni.
