Ibisobanuro ku bicuruzwa
Cobalt-chromium-molybdenum alloy artificiel yubusa ikozwe mubintu byiza byo mu bwoko bwa cobalt-chromium-molybdenum alloy material, ifite imiterere yubukanishi hamwe na biocompatibilité, kandi irashobora gutanga urufatiro rwizewe rwo gukora inganda zujuje ubuziranenge.
Femoral Condyles - Ikintu cyingenzi mububiko bwo gusimbuza amavi butanga umuvuduko mwinshi kandi bigabanya ububabare kubafite ibibazo byingingo.Umugore wigitsina gore nigice cyingenzi cyikivi, gifasha kugabanya uburemere buringaniye no koroshya kugenda mumaguru.
Ikozwe muri cobalt-chromium-molybdenum alloy, ibikoresho bikomeye-bikoreshwa cyane mubuvuzi, ibicuruzwa biraramba.Amavuta azwiho kandi kurwanya ruswa, bigatuma ihitamo neza kubikoresho byubuvuzi.
Imyenda ya femorale ikorwa hifashishijwe uburyo bwo guta ibishashara byatakaye mu nganda imyaka ibihumbi.Ubu buryo bukubiyemo gukora ibishashara byerekana ibicuruzwa bigomba gukorwa, hanyuma bigashyirwa mubibumbano.Icyuma gishongeshejwe noneho gisukwa mubibumbano, byimura ibishashara kandi bigakora kopi nyayo yerekana ibishashara byumwimerere.Ubu buryo butanga ibicuruzwa byujuje ubuziranenge kuko bikozwe neza kandi binareba ko ibicuruzwa byujuje ubuziranenge bw’inganda.
Ikivi nikintu gikomeye gisaba ubuhanga bwuzuye, kandi condyle femorale nayo ntisanzwe.Yakozwe muburyo bwo kwihanganira ± 0.3 mm, yemeza ko ari ukuri kandi ihuye neza nibindi bice mugihe cyo kubagwa.Ubu buhanga bwuzuye nibyingenzi mububiko bwo gusimburana hamwe, kuko itandukaniro iryo ariryo ryose rishobora gutera ibibazo no kutoroherwa kumurwayi.
Usibye ubwubatsi bufite ireme, condyle femorale yubahiriza amahame yinganda YY0117.3-2005 na ISO5832-4, ikarinda umutekano wacyo kugirango ikoreshwe mubuvuzi.Ibipimo ngenderwaho byashizweho kugirango bigenzure umusaruro wibikoresho byubuvuzi no gushyirwaho, bifasha kumenya neza ko bikoreshwa neza kandi byujuje ibisabwa byihariye kugirango bikoreshwe mu mubiri wumuntu.
Ubwiza, condyle femorale ni ibara ryera-ryera.Iri ryari ihitamo ryigishushanyo nkana kuko ryemeza ko ibicuruzwa bishobora kumenyekana byoroshye mugihe cyo gutera.Ibara ryacyo ridasanzwe kandi rifasha inzobere mu buvuzi gutandukanya ibice bitandukanye mugihe cyo kubagwa, bikarushaho kunoza neza uburyo bwo kubaga.
Mu gusoza, condyle femorale ni ikintu cyiza kandi cyingenzi muburyo bwo kubaga ivi.Ikozwe muri cobalt-chromium-molybdenum, ikozwe hifashishijwe uburyo bwo guta ibishashara byatakaye, kandi ikurikiza amahame akomeye y’inganda, bigatuma ihitamo igihe kirekire kandi cyizewe kubuvuzi.Ubwubatsi bwacyo buhanitse hamwe nuburanga budasanzwe nabwo bufasha kunoza ukuri no gukora neza kubaga gusimburana hamwe, amaherezo biganisha kuburambe bwiza bwumurwayi.
