Inhlanganisela Yohlaka Lwendandatho Ekhanyelayo( PEEK )

Umgomo oyisisekelo wokulungisa ukuphuka uwukuzinzisa ithambo eliphukile, ukunika amandla ukuphulukiswa ngokushesha kwethambo elimele, nokubuyisela ukuhamba kwangaphambi kwesikhathi nokusebenza okugcwele komkhawulo olimele.

Ukulungiswa kwangaphandle kuyindlela esetshenziselwa ukusiza ukuphulukisa amathambo aphukile kakhulu. Lolu hlobo lokwelapha lwamathambo luhlanganisa ukuvikela ukuphuka ngomshini okhethekile obizwa ngokuthi i-fixator, ongaphandle komzimba. Kusetshenziswa okukhethekile Izikulufu zamathambo (okuvame ukubizwa ngokuthi izikhonkwane) ezidlula esikhumbeni nasemsipha, isilungisisi sixhunywa ethanjeni elilimele ukuze siligcine lihambisana kahle njengoba liphola.

Isetshenziselwa ini i- Isilungisi sangaphandle ?

Idivayisi yokulungisa yangaphandle ingase isetshenziselwe ukugcina amathambo aphukile ezinzile futhi ehambisana. Idivayisi ingalungiswa ngaphandle ukuze kuqinisekiswe ukuthi amathambo ahlala endaweni efanele ngesikhathi senqubo yokuphulukisa. Le divayisi isetshenziswa kakhulu ezinganeni nalapho isikhumba esingaphezu kokuphuka sonakele.

Yiziphi izinhlobo ze Isilungisi sangaphandle ?

Kunezinhlobo ezintathu eziyisisekelo ze Izilungisi zangaphandle : i-uniplanar fixator ejwayelekile, i-ring fixator, ne-hybrid fixator.

Amadivayisi amaningi asetshenziselwa ukulungisa kwangaphakathi ahlukaniswe cishe ngezigaba ezimbalwa ezinkulu: izintambo, izikhonkwane nezikulufu, amapuleti, nezinzipho noma izinduku ze-intramedullary.

Ama-staples nama-clamp nawo asetshenziswa ngezikhathi ezithile ukuze kulungiswe i-osteotomy noma i-fracture. I-autogenous bone grafts, i-allografts, ne-bone graft substitutes ivame ukusetshenziselwa ukwelapha ukukhubazeka kwamathambo ezimbangela ezihlukahlukene. Ngokuphuka okuthelelekile kanye nokwelashwa kwezifo zamathambo, ubuhlalu be-antibiotic buvame ukusetshenziswa.

Inhlanganisela Yohlaka Lwendandatho Esobala( PEEK ): Intuthuko Yenguquko ku Izifakelo zamathambo

Isingeniso

I-Transparent Ring Frame Combination ( PEEK ) iwukufakelwa kwezokwelapha okwenziwe ngento ye-polymer ebizwa nge-polyether ether ketone ( PEEK ). Lokhu kufakwa kusetshenziselwa ukuhlinzwa kwamathambo, ikakhulukazi ezinqubweni zokuhlanganisa umgogodla, ukunikeza ukusekelwa endaweni ethintekile yomgogodla. Isici esiyingqayizivele salokhu okufakwayo ukubonakala kwayo, okuvumela ukubonwa okungcono kwesayithi lokuhlanganisa phakathi nangemuva kokuhlinzwa.

Umlando we- PEEK ku-Medical Implants

PEEK ibisetshenziswa ekufakweni kwezokwelapha kusukela ngeminyaka yawo-1990s, ikakhulukazi ekufakweni kwamazinyo kanye ne-cranial. Nokho, ukusetshenziswa kwayo kokuthi Izifakelo zamathambo sekuye kwaduma kakhulu eminyakeni yamuva nje ngenxa yamandla ayo aphezulu, i-biocompatibility, kanye ne-radiolucency.

Isebenza Kanjani Inhlanganisela Yozimele Wokukhala Kwendandatho ( PEEK )?

I-Transparant Ring Frame Combination ( PEEK ) iklanyelwe ukuhlinzeka ngosekelo lwesakhiwo endaweni ethintekile yomgogodla phakathi nenqubo yokuhlanganisa. I-implant ibekwe eduze kwe-vertebrae futhi ifakwe endaweni, inikeza ukuzinza nokuqondanisa. Ukucaca kokufakelwa kuvumela odokotela abahlinzayo ukuthi baqaphe inqubo yokuhlanganisa futhi baqinisekise ukuthi ama-vertebrae ahlangana kahle.

Izinzuzo Zokusebenzisa PEEK Izimila

Kunezinzuzo ezimbalwa zokusebenzisa izimila ze PEEK ekuhlinzweni kwamathambo, okuhlanganisa:

• Amandla aphezulu: PEEK okufakwayo kunamandla kunokufakwa kwensimbi okuvamile, okungasiza ekwehliseni ubungozi bokwehluleka kokufakwayo.

• I-Biocompatibility: PEEK izimila zihambisana ne-biocompatible, okusho ukuthi zibekezelelwa kahle umzimba futhi cishe zingabangela ukungezwani noma ukwaliwa.

• I-Radiolucency: PEEK izimila zinokukhanya okukhanyayo, okusho ukuthi azibonakali kuma-X ray noma okunye ukuhlola kwezithombe. Lokhu kuvumela ukubonwa okungcono kwesizinda se-fusion phakathi nangemuva kokuhlinzwa.

• Ingozi encishisiwe yobuthi be-ion yensimbi: Izimila zensimbi zomdabu zingakhulula ama-ion ensimbi emzimbeni, okungabangela izinkinga ezifana nobuthi bensimbi. PEEK izimila azikhiphi ama-ion ensimbi, okwehlisa ingcuphe yale nkinga.

Izicelo Zenhlanganisela Yohlaka Lwendandatho Engafihli ( PEEK )

I-Transparant Ring Frame Combination ( PEEK ) isetshenziswa ngokuyinhloko ezinqubweni zokuhlanganisa umgogodla, kodwa iphinde yasetshenziswa kokunye ukuhlinzwa kwamathambo okufana nokushintshwa kwamalungu kanye nokulungiswa kokuphuka.

Izingozi Ezingenzeka kanye Nezinkinga

Njengazo zonke izinqubo zezokwelapha, kunezingozi ezingaba khona kanye nezinkinga ezihlobene nokusetshenziswa kwezimila ze PEEK . Lokhu kungase kuhlanganise:

• Ukutheleleka

• Ukuhluleka kokufakelwa

• Ukungezwani komzimba

• Ubuhlungu noma ukungakhululeki

• Ukulimala kwezinzwa

Ikusasa le PEEK Izimila

Ukusetshenziswa kwezimila ze PEEK ekuhlinzeni amathambo kuseyintuthuko entsha uma kuqhathaniswa, kodwa sekuvele kubonise isithembiso ekuthuthukiseni imiphumela yesiguli. Njengoba ucwaningo luqhubeka, kungenzeka ukuthi izimila ze PEEK zizovame kakhulu ekuhlinzweni kwamathambo, futhi ekugcineni zingathatha indawo yezimila zensimbi zendabuko ngokuphelele.

Isiphetho

I-Transparant Ring Frame Combination ( PEEK ) iyintuthuko eguquguqukayo ku Izifakelo zamathambo , ehlinzeka ngamandla aphezulu, i-biocompatibility, i-radiolucency, kanye nengozi encishisiwe yobuthi be-ion yensimbi. Ukusetshenziswa kwayo ezinqubweni zokuhlanganiswa komgogodla sekuvele kubonise isithembiso ekuthuthukiseni imiphumela yesiguli, futhi kungenzeka ukuthi izimila ze PEEK zizovame nakakhulu ekuhlinzeni amathambo esikhathini esizayo.
