I-PEEK cage yomlomo wesibeleko yi-radiolucent interbody fusion implant eyenzelwe ukusetyenziswa kwi-discectomy yomlomo wesibeleko kunye neenkqubo ze-fusion (ACDF). Ifakwe phakathi kwemizimba ye-vertebral yomlomo wesibeleko emva kokususwa kwediski ukubuyisela ukuphakama kwediski, ukugcina ukulungelelaniswa komlomo wesibeleko, kunye nokubonelela indawo ezinzileyo yokuxutywa kwamathambo.
Eyenziwe kwi-polyetheretherketone ye-medical-grade (PEEK), olu kufakelwa lusetyenziswa ngokubanzi kunyango lwangoku lomlomo wesibeleko ngenxa yokuhambelana kwayo kwe-biomechanical kunye nethambo kunye nokusebenza kwayo okugqwesileyo kwemifanekiso ngexesha lokulandela emva kokusebenza.
Ukuqonda uMsebenzi weCervical PEEK Cage kwiCervical Spine Surgery
Ikheji ye-PEEK yomlomo wesibeleko isebenza njenge-spacer ye-interbody exhasa ikholamu yangaphambili yomqolo wesibeleko emva koxinzelelo. Ngokugcina indawo ye-intervertebral, i-cage inceda ukugcina ukuphakama kwe-neural foraminal kunye nokunciphisa umngcipheko wokunyanzeliswa kwe-nerve postoperative.
Kwiinkqubo ze-ACDF, i-cage ifakwe emva kokususwa kwe-disc degenerated okanye i-herniated disc. Impahla ye-Bone graft ipakishwe kwi-cage ukukhuthaza ukudibanisa phakathi kwe-vertebrae ekufutshane, ngokuthe ngcembe yenze ibhulorho eqinile yamathambo ngokuhamba kwexesha.
Xa kuthelekiswa nokufakelwa kwesinyithi, iikheji ze-PEEK zivumela oogqirha botyando ukuba bahlole inkqubela ye-fusion ngokucacileyo ngakumbi, edlala indima ebalulekileyo ekuthathweni kwezigqibo emva kokuhlinzwa kunye novavanyo lweziphumo zexesha elide.
Izibonakaliso zeklinikhi kunye nezicelo eziqhelekileyo
Iikheji ze-PEEK zomlomo wesibeleko zivame ukuboniswa kwizigulane ezine-disc ye-disc degenerative, i-cervical disc herniation, kunye ne-spondylosis yomlomo wesibeleko efuna ukuchithwa kwangaphambili kunye nokuzinza. Ezi meko zihlala zibangela intlungu yentamo, i-radiculopathy, okanye i-myelopathy ngenxa yoxinzelelo lwe-nerve okanye i-spinal cord.
Kwiimeko ezikhethiweyo, ukufakelwa kungasetyenziselwa ukuxhatshazwa komlomo wesibeleko okubandakanya ukuwa kwediski okanye ukungazinzi kwecandelo, ngakumbi xa kudibaniswa nenkqubo yangaphambili yomlomo wesibeleko ukunyusa amandla okulungisa.
Ukufakelwa ngokuqhelekileyo kusetyenziswe kumanqanaba omlomo wesibeleko phakathi ukuya kusezantsi, ngokuqhelekileyo ukusuka kwi-C3 ukuya kwi-C7, emele awona macandelo aphathwa rhoqo kwi-ACDF yotyando.
Iimpawu zezinto eziphathekayo kunye neeNgcebiso ze-PEEK kwi-Cervical Fusion
I-PEEK yipolymer esebenza kakhulu ene-elastic modulus ekufutshane naleyo ye-cortical bone kune-titanium. Le propathi ivumela ukwabelana ngomthwalo ongaphezulu ngokwendalo kulo lonke icandelo lodibaniso kwaye inceda ukunciphisa ukhuseleko loxinzelelo, olunxulunyaniswa nokulibaziseka okanye ukudityaniswa okungaphelelanga.
Enye inzuzo enkulu ye-PEEK yi-radiolucency yayo. Ngokungafaniyo neekheji zetsimbi, i-PEEK ayivelisi i-artifacts ye-imaging, eyenza ukubonakala okucacileyo kokukhula kwamathambo kunye nokuqhubela phambili kwe-fusion kwi-X-ray, i-CT, kunye ne-MRI scans.
Ukuxhasa ukufakwa ngokuchanekileyo kokufakelwa, abamakishi be-radiopaque bafakwe ngaphakathi kwe-cage, ukuvumela oogqirha ukuba baqinisekise ukubekwa ngexesha lotyando kunye nomfanekiso we-postoperative ngaphandle kokuphazamisa ukucaca komfanekiso.
Uyilo loLwakhiwo kunye neJiyometri eJongene neFusion
I-Cervical PEEK Cage II yenzelwe iprofayili ye-anatomically contoured ehambelana ne-endplates yomlomo wesibeleko. Olu luyilo lunceda ukusabalalisa umthwalo ngokulinganayo kwimizimba ye-vertebral kunye nokunciphisa umngcipheko wokufakelwa kwe-subsidence.
Ifestile enkulu yegrafti ephakathi ivumela ukupakishwa okwaneleyo kwe-autograft, i-allograft, okanye izinto ezithatha indawo yethambo. Esi sakhiwo esivulekileyo sikhuthaza i-vascularization kunye ne-bone ingrowth, eyona nto ibalulekileyo ekufezekiseni ukudibanisa okuthembekileyo kwe-interbody.
Amazinyo achasene nokufuduka kunye nokuthungwa okungaphezulu kufakwe kwikheji ukuqinisa uzinzo lokuqala kunye nokunciphisa umngcipheko wokufuduka ngexesha lentshukumo yangemva kotyando.
Igalelo kuLungelelwaniso lweCervical and Biomechanical Stability
Ngokubuyisela ukuphakama kwe-disc, i-cage igalelo ekubuyiseleni i-lordosis yomlomo wesibeleko kunye nokulungelelaniswa kwecandelo. Ukulungelelaniswa okufanelekileyo kubalulekile ekunciphiseni uxinzelelo olungaqhelekanga lwe-biomechanical kumacandelo akufutshane kunye nokuphucula iziphumo zeklinikhi zexesha elide.
I-cage isebenza ngokubambisana nezakhiwo ezijikelezayo ze-anatomical kwaye, xa kuyimfuneko, kunye namacwecwe angaphambili omlomo wesibeleko ukubonelela ngenkxaso yomatshini ngokukhawuleza ngelixa i-fusion ikhula ngokuthe ngcembe ngokuhamba kwexesha.
Ukuhambelana ne-Anterior Cervical Fixation Systems
I-Cervical PEEK Cage II yenzelwe ukudibanisa ngokungenamthungo kunye nomgangatho wokuhamba komsebenzi wotyando we-ACDF. Ingasetyenziswa njengesixhobo esizimeleyo se-interbody kwiimeko ezikhethiweyo okanye kudityaniswe nepleyiti yomlomo wesibeleko yangaphambili kunye neenkqubo zokujija ukuqinisa amandla okulungisa.
Uyilo lwayo luyahambelana nesixhobo somlomo wesibeleko esisetyenziswa ngokuqhelekileyo, esivumela oogqirha botyando ukuba bamkele implanti ngaphandle kotshintsho olubalulekileyo kubuchule babo botyando.
Iinketho zobungakanani, iiNgcaciso, kunye neZakhono zokuLungisa
Uluhlu olubanzi lweenyawo kunye nokuphakama kuyafumaneka ukulungiselela izigulane ezahlukeneyo ze-anatomies kunye neemfuno zendawo yediski. Oku kuguquguquka kuvumela oogqirha ukuba bafezekise ukufaneleka kunye nokulungelelaniswa ngexesha lotyando.
Kubathengisi kunye namaqabane e-OEM, iinketho zokwenza ngokwezifiso zinokubandakanya iilebhile zabucala, ulungelelwaniso lokupakisha, kunye nesicwangciso sobungakanani be-assortment ukuhlangabezana neemfuno ezithile zeemarike okanye zokuthengwa kwesibhedlele.
Ukuvala inzala, ukuPakisha, kunye noQinisekiso loMgangatho
Ufakelo lunokunikezelwa kwipakethe engcolileyo okanye engeyontsholongwane ngokuxhomekeke kwimimiselo yengingqi kunye nokukhethwa kwesibhedlele. Zonke iinkqubo zokuvelisa zenziwa phantsi kweenkqubo zolawulo lomgangatho oqinisekisiweyo we-ISO ukuqinisekisa ukungaguquguquki, ukulandeleka, kunye nokhuseleko lwemveliso.
Amaxwebhu abanzi, kubandakanywa iifayile zobugcisa kunye neerekhodi ezisemgangathweni, ziyafumaneka ukuxhasa ukuhanjiswa okulawulwayo kunye nokubhaliswa kweemarike kwimimandla eyahlukeneyo.
Iingqwalasela kuBasasazi, abaThumela kwelinye ilizwe, kunye nabaThengi beZibhedlele
Ngokombono wokuthengwa kwempahla, amandla okubonelela okuhambelanayo kunye nokuchaneka kwe-batch-to-batch dimensional zizinto ezibalulekileyo xa ukhetha umthengisi wokufakelwa komlomo wesibeleko. Iinkqubo zokuvelisa ezizinzileyo zinceda ukuqinisekisa ukusebenza kweklinikhi eqikelelweyo kunye nokufumaneka kwexesha elide.
Ukongeza kumgangatho wemveliso, inkxaso yamaxwebhu kunye nonxibelelwano oluphendulayo luyimfuneko kubasasazi abasebenza kwiimarike zezixhobo zonyango ezilawulwayo.
