Kulwakhiwo ngokutsha lwe-craniomaxillofacial (CMF), ukukhetha imathiriyeli yofakelo efanelekileyo sisigqibo esibalulekileyo esichaphazela ukubuyiswa kokusebenza kunye nobuhle bexesha elide.
Phakathi kokhetho oluninzi olukhoyo, i-3D eprintiweyo yokufakelwa kwe-titanium mesh yotyando ngokukhawuleza ibe lolona khetho lukhethwayo koogqirha kunye nabavelisi bezixhobo zonyango ngokufanayo.
Kodwa yintoni kanye kanye eyenza i-titanium igqwese izinto zemveli ezifana nePEEK, intsimbi engatyiwa, okanye iipolymers ezinokuphinda zisetyenziswe kwi-CMF? Makhe sihlolisise iingenelo eziphambili.
Yintoni iaI-3D-EprintiweyoUfakelo lwe-Titanium yoCwangciso lweMesh?
I-3D eprintiweyo yofakelo lwe-titanium ye-mesh yotyando lufakelo oluthile lwesigulana okanye lwehlabathi jikelele olwenziwe kusetyenziswa ukuveliswa okongeziweyo (ngokuqhelekileyo i-SLM okanye i-EBM) ukwenza i-porous, isakhiwo se-titanium esikhaphukhaphu esilungiselelwe ukwakhiwa kwakhona kwe-cranial okanye isiphene sobuso. Ezi zihlomelo zinokubunjwa ngokwee-CT scans zangaphambili, ziqinisekisa ukuhambelana kwe-anatomical esondeleyo kunye nokunciphisa ixesha lokubunjwa kwe-intraoperative.
Kutheni i-Titanium igqwesa izinto zeMveli
1. I-Biocompatibility ephezulu
Enye yezona zinto zibaluleke kakhulu kulo naluphi na ukufakelwa kotyando yindlela edibana ngayo nomzimba womntu. I-Titanium ibonisa i-biocompatibility egqwesileyo, ebangela impendulo encinci yokuvuvukala okanye ukwaliwa kwezicubu. Xa kuthelekiswa nentsimbi engenasici, enokuthi ikhuphe i-nickel ions kwaye ibangele ukusabela komzimba, i-titanium izinzile ngakumbi kwaye inobuhlobo nezicubu.
Ngaphezu koko, izakhiwo ezinqabileyo ezenziwe ngoshicilelo lwe-3D zivumela i-osseointegration engcono, oku kuthetha ukuba ithambo linokukhula libe yi-mesh, liphucula ukuzinza kwexesha elide kunye nokuphilisa.
2. Ukomelezwa kunye noKuhlala ixesha elide
Ekwakhiweni kwakhona kwe-CMF, ukufakelwa kufuneka kugcine ifomu kunye nokusebenza phantsi koxinzelelo. I-3D eprintiweyo yokufakelwa kwemesh ye-titanium eprintiweyo inika amandla aphezulu okuqina ngelixa ilula. Olu lolona ncedo luphambili ngaphezulu kwe-polymer meshes, enokuthi ikhubaze ngokuhamba kwexesha okanye iswele ubungqongqo obuyimfuneko bokwakhiwa kwakhona okuntsonkothileyo.
Iimeshi ze-Titanium zikwagcina ingqibelelo yoomatshini kwiiprofayili ezibhityileyo, zizenza zilungele iicontours zobuso obubuthathaka ngaphandle kokubeka esichengeni amandla.
3. Ukuchasa iCorrosion kunye nobomi obude
I-Titanium ngokwendalo imelana nokubola kulwelo lomzimba, oluqinisekisa ubomi obude bokufakelwa. Oku kuyenza ifaneleke ngokukodwa ukulungiswa kwe-CMF esisigxina apho ukuthembeka kwexesha elide kubalulekile.
Ngokwahlukileyo koko, ezinye izifakelo zentsimbi zesiNtu zinokuthomalalisa okanye zibe buthathaka ngokuhamba kwexesha, okunokukhokelela kwiingxaki okanye imfuneko yotyando oluhlaziyiweyo.
4. Uyilo lokuguquguquka kunye noShicilelo lwe-3D
Imida yokwenziwa kwezinto zokufakelwa kwesiqhelo. Nangona kunjalo, ngokwenza okongeziweyo, i-3D eprintiweyo yofakelo lwe-titanium mesh yotyando inokuveliswa ngeejometri ezintsonkothileyo ezilungiselelwe i-anatomy yesigulana. Oogqirha botyando banokufezekisa uhlengahlengiso oluchanekileyo ngakumbi, ngakumbi kwiziphene ezingaqhelekanga okanye ukukhubazeka okusemva kokwenzakala.
Ngaphaya koko, ukukwazi ukulawula ukutyeba komnatha, ubungakanani bepore, kunye nokugoba konyusa ukusebenza kuzo zonke iimeko ezahlukeneyo ze-CMF-ukusuka ekwakhiweni komgangatho we-orbital ukuya kulungiso lwe-mandible.
Izicelo zelizwe lokwenyani kwiCMF Surgery
I-Titanium meshes ngoku isetyenziswa ngokubanzi kwi:
Ukwakhiwa kwakhona komgangatho we-Orbital-Iprofayili yabo ebhityileyo kunye namandla abenza bagqibelele ukuxhasa izakhiwo zamehlo ezibuthathaka.
I-Mandibular contouring – Iimeshes eziqhelekileyo zibuyisela umsebenzi we-jawline kunye ne-symmetry emva kwe-tumor resection okanye ukwenzakala.
Ukulungiswa kwesiphako se-Cranial - Iziphene ezinkulu zinokubuyiselwa kunye ne-meshes ethile yesigulane edibanisa ngokungenamthungo kunye nekhanda.
Kuzo zonke ezi zicelo, i-3D eprintiweyo ye-titanium mesh yotyando ifakela ngaphezulu kwemathiriyeli yelifa ngokuchaneka, isantya sokuphilisa, kunye neziphumo zobuhle.
Inyathelo eliya Phambili kuLwakhiwo ngokutsha lwe-CMF olusekelwe kwiSigulana
Ujoliso lwanamhlanje lotyando alukho nje ekulungiseni iziphene, kodwa ekubuyiseleni inkangeleko, i-symmetry, kunye nomgangatho wobomi bexesha elide. I-Titanium mesh, xa idibene ne-digital imaging kunye ne-3D yokushicilela, ihambelana ngokugqibeleleyo nale njongo. Ivumela oogqirha botyando ukuba bacwangcise utyando ngokufanelekileyo kwaye banike izigulane iziphumo ezisebenzayo kunye nezanelisayo ezibonakalayo.
UKhetho oluSmart kwiiNgcali zeCMF
Njengoko utyando lwe-CMF lusiya lusiba lolwakho kwaye luntsonkothile, ukukhetha imathiriyeli efanelekileyo yokufakelwa kubalulekile. I-3D eprintiweyo yokufakelwa kwemesh ye-titanium inikezela indibaniselwano enamandla yamandla, ukuguquguquka, kunye ne-biocompatibility, izenza zibe yimathiriyeli yokhetho lwamaqela otyando acinga phambili.
Masithi ufuna izisombululo ezikumgangatho ophezulu we-titanium mesh ezilungiselelwe izicelo zakho zeCMF. Kwimeko apho, iqela lethu eShuangyang Medical lisebenza ngokukhethekileyo kwi-3D eprintiweyo yokufakelwa kwe-titanium mesh ye-OEM kunye neemfuno zeklinikhi.
