Umdibaniso weSakhelo seRingi eTransparant(PEEK)

Injongo esisiseko yokulungiswa kwe-fracture kukuzinzisa ithambo eliqhekekileyo, ukunika amandla ukuphulukiswa ngokukhawuleza kwethambo elenzakeleyo, kunye nokubuyisela ukuhamba kwangaphambili kunye nomsebenzi opheleleyo wesigxina esonzakeleyo.

Ukulungiswa kwangaphandle bubuchule obusetyenziselwa ukunceda ukuphilisa amathambo aphukile kakhulu. Olu hlobo lonyango lwamathambo lubandakanya ukukhusela ukuphuka ngesixhobo esikhethekileyo esibizwa ngokuba yi-fixator, engaphandle komzimba. Ukusebenzisa i-screws yethambo ekhethekileyo (ebizwa ngokuba yizikhonkwane eziqhelekileyo) ezidlula esikhumbeni kunye nemisipha, i-fixator ixhunywe kwithambo elonakeleyo ukuze ligcinwe ngokufanelekileyo njengoko liphilisa.

Yintoni isilungisi sangaphandle esisetyenziselwa ntoni?

Isixhobo sokulungiswa kwangaphandle singasetyenziselwa ukugcina amathambo aphukileyo azinzile kwaye alungelelanise. Isixhobo sinokuhlengahlengiswa ngaphandle ukuze kuqinisekiswe ukuba amathambo ahlala kwindawo efanelekileyo ngexesha lenkqubo yokuphulukisa. Esi sixhobo sisetyenziswa ngokuqhelekileyo kubantwana kwaye xa ulusu phezu kwe-fracture lonakalisiwe.

Ziziphi iintlobo zesilungisi sangaphandle?

Kukho iintlobo ezintathu ezisisiseko zokulungiswa kwangaphandle: i-standard uniplanar fixator, i-ring fixator, kunye ne-hybrid fixator.

Izixhobo ezininzi ezisetyenziselwa ukulungiswa kwangaphakathi zahlulahlulwe ngokweendidi ezimbalwa eziphambili: iingcingo, izikhonkwane kunye nezikrufu, iipleyiti, kunye nezikhonkwane ze-intramedullary okanye iintonga.

I-Staples kunye ne-clamps zikwasetyenziswa ngamaxesha athile kwi-osteotomy okanye ukulungiswa kwe-fracture. I-autogenous bone grafts, i-allografts, kunye ne-bone graft substitutes zihlala zisetyenziselwa unyango lweziphene zamathambo zezizathu ezahlukeneyo. Ukwaphuka okusulelekileyo kunye nokunyangwa kosulelo lwethambo, amaso okubulala iintsholongwane asetyenziswa rhoqo.

Umdibaniso weSakhelo seRingi eTransparant(PEEK): iNguqulelo ePhambili kwiZihlomelo zeOrthopedic

Intshayelelo

I-Transparent Ring Frame Combination (PEEK) sisifakelo sonyango esenziwe ngezinto zepolymer ezibizwa ngokuba yi-polyether ether ketone (PEEK). Olu kufakelwa lusetyenziselwa utyando lwamathambo, ngokukodwa kwiinkqubo zokudibanisa umgogodla, ukubonelela ngenkxaso kwindawo echaphazelekayo yomqolo. Into ekhethekileyo yolu fakelo kukucaca kwayo, okuvumela ukubonwa okungcono kwendawo yokudibanisa ngexesha nasemva kotyando.

Imbali ye-PEEK kwi-Medical Implants

I-PEEK isetyenziselwe ukufakelwa kwezonyango ukususela ngo-1990, ngokuyinhloko kumazinyo kunye nokufakelwa kwe-cranial. Nangona kunjalo, ukusetyenziswa kwayo kukufakelwa kwe-orthopedic kuye kwanda ukuthandwa kwiminyaka yakutshanje ngenxa yamandla ayo aphezulu, i-biocompatibility, kunye ne-radiolucency.

Isebenza Njani iNdibaniselwano yeSakhelo seRingi eNgaphandle (PEEK)?

I-Transparant Ring Frame Combination (PEEK) yenzelwe ukubonelela ngenkxaso yesakhiwo kwindawo echaphazelekayo yomqolo ngexesha lenkqubo yokudibanisa. Ukufakelwa kufakwe malunga ne-vertebrae kwaye i-screw endaweni, inika uzinzo kunye nokulungelelaniswa. Ukucaca kokufakela kuvumela oogqirha botyando ukuba babeke iliso kwinkqubo yokudibanisa kunye nokuqinisekisa ukuba i-vertebrae idibanisa ngokufanelekileyo.

Izinto eziluncedo zokuSebenzisa i-PEEK Implants

Kukho iingenelo ezininzi zokusebenzisa ukufakelwa kwe-PEEK kuqhaqho lwamathambo, kubandakanya:

• Amandla aphezulu: Ukufakelwa kwe-PEEK kunamandla kunokufakelwa kwentsimbi yesiko, enokunceda ukunciphisa umngcipheko wokungaphumeleli kokufakelwa.

• I-Biocompatibility: Ukufakelwa kwe-PEEK kuhambelana ne-biocompatible, oku kuthetha ukuba kunyamezelwa kakuhle ngumzimba kwaye akunakwenzeka ukuba kubangele ukusabela okanye ukugatywa.

• I-Radiolucency: Ukufakelwa kwe-PEEK ku-radiolucent, okuthetha ukuba azibonakali kwi-X-reyi okanye ezinye iimvavanyo ze-imaging. Oku kuvumela ukubonwa okungcono kwendawo yokudibanisa ngexesha nasemva kotyando.

• Ukunciphisa umngcipheko we-ion ye-metal toxicity: Ukufakelwa kwensimbi yendabuko kunokukhupha ii-ion zetsimbi emzimbeni, ezinokubangela iingxaki ezifana netyhefu yensimbi. Ukufakelwa kwe-PEEK akukhululi i-ion zetsimbi, ukunciphisa umngcipheko wale ngxaki.

Usetyenziso lweNdibaniselwano yeSakhelo seRingi eTransparant (PEEK)

I-Transparant Ring Frame Combination (PEEK) isetyenziswe ngokukodwa kwiinkqubo zokuxutywa komgogodla, kodwa iphinde isetyenziswe kolunye utyando lwamathambo olufana nokutshintshwa kwamalungu kunye nokulungiswa kwe-fracture.

Imingcipheko enokubakho kunye neengxaki

Njengazo zonke iinkqubo zonyango, kukho imingcipheko enokubakho kunye neengxaki ezinxulumene nokusetyenziswa kwe-PEEK implants. Oku kunokubandakanya:

• Usulelo

• Ukusilela kofakelo

• Ukwaliwa

• Intlungu okanye ukungakhululeki

• Ukonakala kwemithambo-luvo

Ikamva le-PEEK Implants

Ukusetyenziswa kwe-PEEK implants kwi-orthopedic surgeries kuseyinto entsha, kodwa sele ibonise isithembiso ekuphuculeni iziphumo zesigulane. Njengoko uphando luqhubeka, kusenokwenzeka ukuba ukufakelwa kwe-PEEK kuya kuxhaphaka ngakumbi kuqhaqho lwamathambo, kwaye ekugqibeleni kunokutshintsha ukufakelwa kwentsimbi yesiko ngokupheleleyo.

Ukuqukumbela

I-Transparant Ring Frame Combination (PEEK) yinkqubela phambili yoguquko kukufakelwa kwe-orthopedic, enika amandla aphezulu, ukuhambelana kwezinto eziphilayo, i-radiolucency, kunye nokunciphisa umngcipheko wetyhefu ye-ion yesinyithi. Ukusetyenziswa kwayo kwiinkqubo ze-spinal fusion sele ibonise isithembiso ekuphuculeni iziphumo zesigulane, kwaye kunokwenzeka ukuba i-PEEK implants iya kuba yinto eqhelekileyo ngakumbi kwi-orthopedic surgeries kwixesha elizayo.
