Otu ọnwa gara aga, ihe mgbu úkwù aka ekpe nke onye ọrịa ahụ ka njọ. Na mbido Febụwarị afọ a, onye ọrịa ahụ gara Ụlọ Ọgwụ Tongliang District nke Chongqing ma banye na Ngalaba Njikọ nke 1 nke Ngalaba Orthopedics n'ihi "mgbaji ochie nke olu aka ekpe femoral; necrosis isi femoral aka ekpe; ọbara mgbali elu; ọrịa obi akwara".
● Nnyocha Ndị Inyeaka: Nnyocha CT, Nnyocha X-ray
● Nchọpụta Tupu Awa Ahụ: Ọkpụkpụ ochie nke olu femoral aka ekpe; necrosis nke isi femoral aka ekpe
● Atụmatụ Ọgwụgwọ: Mgbanwe úkwù zuru oke nke akụkụ aka ekpe
● Mmecha Ịwa Ahụ: N'okpuru nduzi dọkịta, etinyere ihe mkpuchi nkwonkwo úkwù nke Beijing Zhongantaihua (ZATH) nke ọma. Awa ahụ mechara nke ọma, ihe mgbaàmà dị mkpa nke onye ọrịa ahụ kwụsiri ike.
Kedu ụdị ihe e ji eme úkwù?
1, isi bọọlụ ígwè na polyethylene (plastic) mkpuchi
A na-eji bọọlụ ígwè nkịtị na ihe mkpuchi iko polyethylene eme ihe kemgbe mmalite afọ 1960. Nnyocha sayensị na-egosi na iji ihe mkpuchi polyethylene emelitere, nke a maara dị ka ihe mkpuchi polyethylene "nke jikọtara ọnụ nke ukwuu", nwere ike ibelata oke mmebi nke ihe ndị e tinyere n'ime ya. N'ihi ịdịte aka ya na ihe ndị ọzọ metụtara ya, polyethylene metallic abụrụla ihe a na-ahọrọ maka ndị dọkịta na-awa ahụ maka nkwonkwo úkwù arụrụ arụ kemgbe e mere ịwa ahụ mbụ maka mgbanwe úkwù. A na-eji cobalt-chromium alloy mee bọọlụ ígwè ahụ, a na-ejikwa polyethylene mee mkpuchi ahụ.
2, Isi bọọlụ seramiiki na polyethylene (plastic) mkpuchi
Isi seramiiki siri ike karịa ígwè ma bụrụkwa ihe kacha egbochi nkụ. Seramiiki eji eme ihe ugbu a n'ịwa ahụ nkwonkwo nwere elu siri ike, na-eguzogide nkụ, na-adị nro nke ukwuu nke nwere ike ibelata oke iyi nke njikọ esemokwu polyethylene. Oke iyi nke ihe a na-etinye n'ime ihe a dị ala karịa oke iyi nke ígwè na polyethylene.
3, Isi bọọlụ ígwè na ihe mkpuchi ígwè
E jirila njikọ esemokwu ígwè na ígwè (cobalt-chromium alloys, mgbe ụfọdụ ígwè anaghị agba nchara) mee ihe na mbido afọ 1955, mana FDA anabataghị ha maka ojiji na United States ruo afọ 1999. Ka teknụzụ na-aga n'ihu, iyi na-ebelata nke ukwuu, na-eme ka mbufụt na mfu ọkpụkpụ dị obere. A na-enweta bearings ígwè n'ọtụtụ nha (site na 28mm ruo 60mm), yana ọtụtụ nhọrọ ogologo olu. Agbanyeghị, akụkọ ogologo oge mgbe ịwa ahụ gasịrị na-egosi na metal, dị ka ion na-arụ ọrụ nke ọma, na-achịkọta ihe mkpofu ígwè n'ihi mmebi na ndọda ogologo oge, nke nwere ike ibute mgbasa ọkpụkpụ gburugburu prosthesis nkwonkwo, na-eduga na mwepụ na mgbanwe nke prosthesis nkwonkwo. Ọrụ ahụ dara.
4, Isi bọọlụ seramiiki na mkpuchi seramiiki
N'ime usoro nkwonkwo úkwù ndị a e ji aka rụọ, a na-eji seramiiki siri ike dochie bọọlụ ígwè ọdịnala na ihe mkpuchi polyethylene, nke a maara maka ihe ndị na-adịghị emebi emebi. Agbanyeghị, ọ bụ ezie na ha nwere uru dị elu na obere iyi, ha nwekwara ọghọm nke ọnụ ahịa dị elu.
Ọ bụrụ na ịchọrọ ịmatakwu gbasara ya nkwonkwo úkwùihe ọmụma, biko nweere onwe gịkpọtụrụ anyị; ndị otu anyị ga-enye gị nkwado ọkachamara na azịza.
