Kwintsimi ye-maxillofacial trauma kunye nokwakhiwa kwakhona, ubunzima be-bone anatomy kunye neemeko zokulayisha zibeka iimfuno eziphezulu kakhulu kwizixhobo zokulungiswa kwangaphakathi. Phakathi kwezi, i-mini bone plate-efana ne-Locking Maxillofacial Mini Straight Plate-ye yaba sisisombululo esibalulekileyo sokuzinzisa iifractures kwiindawo ezibuthathaka zobuso.
Eli nqaku liphonononga izinto ezintsha zobunjineli zamva njeiipleyiti zamathambo amancinci, kugxininise ekukhethweni kwezinto eziphathekayo, ukuyila isithuba sokuvula imingxuma, kunye nokuphuculwa kwesakhiwo sokutshixa okuphucula ukusebenza kotyando kunye nokuzinza kwexesha elide.
Ukuveliswa kwezinto ezintsha: UBongame be-Titanium kunye ne-Titanium Alloys
Ukukhethwa kwezinto eziphathekayo kusisiseko kuyilo lweenkqubo zokulungisa amathambo. Iipleyiti zethambo ezincinci kufuneka zifezekise ibhalansi ye-biocompatibility, amandla oomatshini, ukuxhathisa ukukhathala, kunye nokuhambelana kwe-radiographic. I-Titanium kunye ne-alloys yayo iye yavela njengomgangatho wegolide kule ndawo.
I-Locking Maxillofacial Mini Straight Plate esuka eShuangyang yenziwe kwi-medical-grade pure titanium, ikhutshwe ngokukodwa kwi-German ZAPP izinto ze-titanium. Oku kuqinisekisa ukuba i-biocompatibility egqwesileyo, i-fine-grain uniformity, kunye nokuphazamiseka okuncinci kwe-imaging-inzuzo ephambili kwi-postoperative CT kunye noviwo lwe-MRI.
Ngokwembono yobunjineli, i-titanium ibonelela ngeenzuzo ezininzi eziphambili:
I-Biocompatibility ephezulu:
I-Titanium ngokwemvelo yenza i-TiO₂ oxide layer ezinzileyo kumphezulu wayo, okhuthaza i-osteointegration kunye nokuthintela ukubola kwimeko yebhayoloji.
Amandla aphezulu kunye nokuNyanga ukudinwa:
I-alloys ye-Titanium efana ne-Ti-6Al-4V okanye i-Ti-6Al-7Nb ibonisa amandla agqwesileyo kunye nokuguquguquka, ukuvumela ipleyiti yethambo ukuba imelane noxinzelelo lwe-cyclic mechanical ngexesha lokuxhamla kunye nokuphilisa.
Ukuhambelana komfanekiso:
Ngokungafani nensimbi engenasici okanye izinto ze-cobalt-chromium, i-titanium ivelisa izinto ezincinci kwi-CT okanye i-MRI scans, eyenza ukuba kuhlolwe ngokucacileyo emva kokusebenza.
Ukongeza, ipleyiti yethambo encinci ibonakalisa unyango lwe-anodized surface, oluphucula ubulukhuni, ukuxhathisa ukunxiba, kunye nobomi bokufakelwa ngokupheleleyo. Ukusuka kwimbono yobunjineli, i-anodization iphinda iphucule i-microstructure ye-oxide, iphucula ukunyamezela kwayo kunye nokumelana nokubola.
Ngelixa i-titanium sele imiselwe kakuhle, ukuphuculwa okuqhubekayo kusalandelwa-ingakumbi kwi-microstructure refinement, ukulawulwa kwengcinezelo eseleyo, kunye nokuguqulwa komphezulu-ukwandisa ukuqina kokufakelwa kunye nokunciphisa ukukhululwa kwe-ion yensimbi ngokuhamba kwexesha.
Isithuba soMngxuma kunye noYilo lweJiyometri: Ukuzinzisa ukulinganisa kunye neAnatomy
Ijometri yepleyiti yethambo elincinci-kubandakanya ubukhulu bayo, isithuba somngxuma, kunye nobude-idlala indima ebalulekileyo ekusebenzeni kwayo koomatshini kunye nokuguquguquka kotyando.
Uluhlu lwe-Locking Maxillofacial Mini Straight Plate lubonisa ulungelelwaniso oluninzi, kubandakanywa i-6-hole (35 mm), i-8-hole (47 mm), i-12-hole (71 mm), kunye ne-16-hole (95 mm) iinketho, zonke ezinobunzima obuqhelekileyo be-1.4 mm. Ezi zintlukwano zivumela oogqirha ukuba bakhethe ulungelelwaniso olufanelekileyo olusekelwe kuhlobo lokuphuka, ukumila kwethambo, kunye neemfuno zokulungiswa.
Ukusuka kwimbono yobunjineli, isithuba somngxuma (umgama phakathi kwamaziko okujija) uchaphazela ngokuthe ngqo iiparamitha ezininzi ezibalulekileyo:
Ukusasazwa koxinzelelo:
Isithuba esigqithileyo singakhokelela ekugobeni okanye ukudinwa phantsi kokulayisha okusebenzayo, ngelixa isithuba esincinci kakhulu singenza buthathaka icandelo lethambo kunye nokwandisa umngcipheko wokukhupha i-screw. Isithuba esilungiselelweyo siqinisekisa ukuhanjiswa komthwalo ofanayo phakathi kwethambo kunye nenkqubo yokulungisa.
I-Bone-Screw Interface:
Isithuba esifanelekileyo siqinisekisa ukuba isikrufu ngasinye sinegalelo ngokufanelekileyo ekuthwaleni umthwalo ngaphandle kokuvelisa iincopho zoxinzelelo lwasekuhlaleni ezinokukhawulezisa ukusilela kokudinwa.
Ukuziqhelanisa noCando:
Ipleyiti kufuneka ihambelane ngokuchanekileyo nomgangatho wethambo, ngakumbi kwiikhonto ezigobileyo zommandla we-maxillofacial. Ijiyometri yomngxuma kunye nezithuba ziyilwe ngononophelo ukuvumela i-angulation ye-screw eguquguqukayo ngelixa unqanda ukuphazamisana nezakhiwo ezimeleneyo ze-anatomical.
Uphononongo lwe-Finite element (FEA) kwiipleyiti zamathambo ezincinci ezifanayo zibonise ukuba isithuba semingxuma esingalungiswanga kakuhle sinokwandisa uxinzelelo lwe-von Mises ngaphaya kwamandla esivuno se-titanium, ukunciphisa ubomi bokudinwa. Ke ngoko, isithuba esichanekileyo kunye nejometri yomngxuma engaguqukiyo zizinto eziphambili zobunjineli kuyilo lweepleyiti.
UPhuculo lweNdlela yokutshixa: Ukusuka kwi-Passive Fixation ukuya kuZinzo oluSebenzayo
Iipleyiti zemveli ezingavaliyo zixhomekeke kwingxabano phakathi kwepleyiti kunye nomgangatho wethambo ukuze uzinze. Nangona kunjalo, kwimeko eguquguqukayo kunye ne-anatomically eyinkimbinkimbi yobuso, olu hlobo lokulungiswa lunokuthi lube lula ukukhulula okanye ukutyibilika.
Iipleyiti ezincinci zanamhlanje zokutshixa-njengalezo zikwiNkqubo yokutshixa i-Maxillofacial-zidibanisa i-interface yokutshixa ngomatshini phakathi kwentloko ye-screw kunye ne-plate, ukudala isakhiwo esisodwa, esidibeneyo. Olu tshintsho lubonisa ukutsibela phambili okukhulu kuzinzo kunye nokuchaneka.
Indlela yokutshixa esetyenziswa kwiPleyiti yokuTshixa iMaxillofacial Mini Straight:
Itekhnoloji yokutshixa itekhnoloji iqinisekisa unxibelelwano oluqinileyo phakathi kwabasebenzi kunye nepleyiti.
Uyilo lwemingxuma olusetyenziswa kabini, luhambelana nezikrufu zombini zokutshixa kunye nezingatshixwanga, ukubonelela ukuguquguquka okukhulu ngexesha lotyando.
Izibonelelo zobunjineli zenkqubo yokutshixa ziquka:
Ukomelezwa koBungqongqo kunye nozinzo:
I-interface ye-screw-plate evaliweyo isebenza njenge-internal fixed-angle construct, ukuphucula ukuhanjiswa komthwalo kunye nokunciphisa i-micromotion kwindawo yokuphuka.
UkuNcitshiswa Kwethambo:
Kuba ipleyiti ayisaxhomekekanga kungquzulwano lwamathambo, inqanda ukucinezelwa okugqithisileyo kwiperiosteum, igcina unikezelo lwegazi kunye nokukhuthaza ukuphiliswa kwamathambo ngokukhawuleza.
Ukuphucula Ukuxhathisa Ukudinwa:
Ngokuthintela ukutyibilika kancinci phakathi kwentloko yesijiva kunye nomngxuma wepleyiti, ujongano lokutshixa lunciphisa uxinzelelo lokucheba lwendawo kwaye lwandise ubomi benkonzo yokufakelwa.
Olu phuculo lufuna ukunyamezelwa komatshini okuchane kakhulu, ngakumbi kwimisonto kunye ne-angulation ye-screw-plate interface. Ukuchaneka kokwenziwa kwemveliso kubonisa ukukhula kobunjineli beenkqubo zanamhlanje zokulungisa.
