Rau cov neeg mob uas tab tom yuav hloov pob qij txha lossis tab tom xav txog kev hloov pob qij txha yav tom ntej, muaj ntau qhov kev txiav txim siab tseem ceeb uas yuav tsum tau ua. Ib qho kev txiav txim siab tseem ceeb yog kev xaiv qhov chaw txhawb nqa prosthetic rau kev hloov pob qij txha: hlau-rau-hlau, hlau-rau-polyethylene, ceramic-rau-polyethylene, lossis ceramic-rau-ceramic. Qee zaum, qhov no tuaj yeem yog qhov teeb meem!
Kev phais hloov lub duav tag nrho tuaj yeem siv los hloov lub pob qij txha pob qij txha, siv ib qhohip itsob nrojkom tshem tawm qhov mob los ntawm kev sib txhuam ntawm cov nto.
Lub duavjqhov tseem ceebpkev kho mob rosthesistau tsim los muab kev ruaj khov rau cov neeg mob thiab txo qhov hnav thiab rhuav. Cov hlau thiab polyethylene cog hniav ib txwm muaj tau siv txij li xyoo 1960, tab sis kev nce qib hauv thev naus laus zis tau ua rau cov khoom siv ceramic thiab lwm yam khoom siv tau nrov zuj zus.
Kev Kho Mobhip jqhov tseem ceebcov ntaub ntawv.
Ib qho teeb meem uas tshwm sim ntau tshaj plaws tom qab hloov lub duav yog qhov hnav thiab rhuav ntawm cov pob qij txha prosthesis los ntawm kev siv ib txwm muaj. Nyob ntawm tus neeg mob qhov xwm txheej tshwj xeeb, xws li hnub nyoog, qhov loj me, qib kev ua ub no, thiab tus kws phais mob txoj kev paub nrog cov khoom cog tshwj xeeb, Lubokws kho mob pob qij txhahip icov nroj tsuagtej zaum yuav ua los ntawm hlau, polyethylene (yas), lossis ceramic. Piv txwv li, yog tias tus neeg mob nquag heev lossis tseem hluas thiab xav tau kev txav mus los ntau tom qab phais, tus kws phais pob txha yuav pom zoo kom siv ceramic implant rau lub duav.
1, Lub taub hau pob hlau thiab polyethylene (yas) sab hauv
Cov pob hlau txheem thiab cov hnab yas polyethylene tau siv txij li thaum xyoo 1960. Kev tshawb fawb qhia tau hais tias kev siv cov hnab yas polyethylene zoo dua, hu ua "highly cross-linked" polyethylene liners, tuaj yeem txo qhov hnav ntawm cov hniav cuav. Vim nws lub zog thiab lwm yam khoom muaj feem cuam tshuam, cov polyethylene hlau tau yog cov khoom siv xaiv rau cov kws phais pob txha rauacuavhip jqhov tseem ceebtxij li thaum thawj zaug phais hloov lub duav tau ua tiav. Lub pob hlau yog ua los ntawm cobalt-chromium alloy thiab lub sab hauv yog ua los ntawm polyethylene.
2, Lub taub hau pob ceramic thiab polyethylene (yas) sab hauv
Cov taub hau ceramic nyuaj dua hlau thiab yog cov khoom siv cog hniav uas tiv taus khawb tshaj plaws. Cov ceramics uas siv rau hauv kev phais hloov pob qij txha tam sim no muaj cov nto tawv, tiv taus khawb, thiab du heev uas tuaj yeem txo qhov kev hnav ntawm cov polyethylene sib txhuam interfaces. Qhov kev hnav ntawm cov khoom cog hniav no qis dua qhov kev hnav ntawm cov hlau ntawm polyethylene.
3,Lub taub hau pob hlauthiab hlau liner
Cov hlau sib txhuam sib txuas (cobalt-chromium alloys, qee zaum stainless hlau) tau siv thaum ntxov li xyoo 1955, tab sis FDA tsis tau pom zoo rau kev siv hauv Tebchaws Meskas txog xyoo 1999. Raws li thev naus laus zis nce qib, kev hnav tau txo qis heev, ua rau muaj kev o thiab pob txha poob tsawg dua. Cov kabmob hlau muaj ntau qhov ntau thiab tsawg (xws li 28mm txog 60mm), nrog rau ntau yam kev xaiv ntev ntawm caj dab. Txawm li cas los xij, cov ntawv ceeb toom tom qab phais ntev qhia tias hlau, ua ib qho ion nquag, khaws cov hlau khib nyiab vim yog kev hnav thiab tsim kua muag ntev, uas tuaj yeem ua rau pob txha yaj nyob ib puag ncig cov pob qij txha prosthesis, thaum kawg ua rau loosen thiab deformation ntawm cov pob qij txha prosthesis. Kev phais tsis ua tiav.

Hauv cov noacuavhip jqhov tseem ceebslub kaw luss, cov pob hlau ib txwm muaj thiab cov polyethylene liners tau hloov los ntawm cov khoom siv ceramics muaj zog heev, uas paub txog lawv cov khoom siv hnav tsawg heev. Txawm li cas los xij, thaum muaj qhov zoo ntawm kev zoo thiab kev hnav tsawg, lawv kuj muaj qhov tsis zoo ntawm tus nqi siab.
Qhov kev xaiv kawg ntawmhip jqhov tseem ceebitsob nrojyuav raug txiav txim siab raws li tus neeg mob cov yam ntxwv kev noj qab haus huv tshwj xeeb thiab tseem yuav xav tau tus kws phais pob txha txoj kev txawj ntse, kev kawm, thiab kev txawj ntse los kho kom haum rau cov khoom tsim tshwj xeeb. Yog li ntawd, nws yog ib qho tsim nyog los tham nrog koj tus kws phais pob txha ua ntej phais kom nkag siab txog hom kev cog hniav uas lawv npaj siab siv rau koj qhov kev phais hloov lub duav, thiab cov laj thawj rau kev xaiv kev cog hniav tshwj xeeb.
