Sisiteme ya titanium posterior spinal fixation ya switirhisiwa swo tiyisisa occipitocervical, khwiri ra le henhla na ra le hansi ra khwiri.
Titanium ya xirhendzevutani
3.5mm nhonga leyi nga cinciki
Ku khomiwa ka le ndzhaku ka screw-rod
Sisiteme yi nyikeriwile hi tindlela to tala to khoma occipital, dizayini ya nhonga ya 3.5mm ya xiyimo xa le hansi, switirhisiwa swo hlawula eka mikhuva yo hambana ya tliliniki, na xivumbeko xa xikurufu xa polyaxial xa ku lulamisiwa ka xivumbeko lexi cinca-cincaka.
Maendlelo yo hambana ya occipital fixation yanga hlawuriwa kuya hi kutsakela ka dokodela wa vuhandzuri na swilaveko swa xiyimo.
Endlelo leri ritirhisa 3.5mm diameter fixed rod leyingana lower-profile posterior fixation construct.
Switirhisiwa swo hlawula swa kumeka ku seketela mikhuva yo hambana ya tliliniki na ku tsakela ka maendlelo ya ntirho ya vuhandzuri.
Dizayini yale hansi yi pfuneta ku hunguta ku hlohleteriwa ka ti soft tissue leti rhendzeleke ku rhendzela construct.
Dizayini ya thyaka ra negative-angle yi pfuneta ku sivela voko ra screw leswaku ri nga andzi.
Dizayini ya xikwirikiri xa polyaxial xa xivumbeko xo hlawuleka yi seketela ku famba lokukulu ka tlhelo rin’we ku fika eka 55°.
Nhundzu ya endlelo yi lulamisiwile tanihi makhadi ya swivono leswaku yi hlaya ku antswa eka inthanete ku tlula ku hangalasiwa ka PDF yo sungula. Hlayisa xitiviso xa matirhiselo ya xiphurofexinali ehenhla ka xiyenge lexi loko u kandziyisa.
Muvabyi u vekiwa eka xiyimo xo olova ku fana na standard midline posterior cervical incision. Pfuxeta marhambu ya occipital, arch yale ndzhaku ya atlas, na articular mass na arch ya xiphemu xa cervical leswi lavaka ku hlanganisiwa.
Endzhaku ko kumisisa ndzhawu yo nghena na angle yo nghena, marhambu ya cortical ya boriwa hi open drill naswona khumbi ri kurisiwa.
Ndzhawu yo nghena eka screw yi hlamuseriwa tani hi kuya endzeni kuya eka ndzhawu yale xikarhi ya side mass na 2mm kuya e henhla. Angle yo nghena yi rhetela ehandle 20°-25° naswona yi kongoma emakumu ya nhloko 30°-40°, yi fambelana na vuandlalo bya articular lebyi nga ekusuhi.
Ku vekiwa kahle ka swikwirikiri swa le hansi swa cervical C3-C7 swi pfuneta ku hunguta khombo ra vertebral artery na nerve loko swiri karhi swinyika ku leha lokukulu ka screw xikan’we naku khomiwa lokunene.
Lower cervical C3-C7: ndzhawu yo nghena eka screw i 2-5mm endzeni ka tlhelo ra le handle ra side block na 2-3mm ehansi ka base ya articular surface ya upper facet. Angle yo nghena i 30°-45° endzeni ka coronal plane, laha sagittal plane yi fambelanaka na endplate yale henhla.
Upper cervical C1-C2: C1 lateral mass screw entry yi hlamuseriwa kwalomu ka 18-20mm etlhelo ka ndzhawu yale xikarhi ya posterior tubercle ya atlas, laha vuenti byi lawuriwaka kwalomu ka 28mm. C2 pedicle screw entry yi hlamuseriwa exikarhi ka layini yo yima exikarhi ka lateral mass, laha ku enta hi xitalo kwalomu ka 24-26mm.
Tinhlamuselo leti ta ku nghena ka swikwirikiri i nhundzu ya swikombo swa xiphurofexinali ku suka eka IFU naswona swi titshege hi xiyimo xo karhi xa vuhandzuri.
Tirhisa drill bit na guide ku bora naku kumisisa vuenti lebyi faneleke ku boriwa. Lulamisa nkongomiso eka xikalo lexi fambelanaka ku hunguta vuenti.
Lawula rivilo ra ku bora na vuenti hi ku hetiseka kuya hi datha leyi pimiweke. Yimisa ku bora hiku hatlisa loko se u fika eka vuenti lebyi vekiweke ka ha ri emahlweni ku papalata ku nghena ngopfu ka vertebral cortex xikan’we naku onhaka ka peripheral nerve kumbe vascular tissue.
Susa drill bit endzhaku ka loko hole yi herile kutani u basisa marhambu lawa yanga endzeni ka pilot hole.
Ku enta ka ndlela ya swikwirikiri swi pimiwa hi depth gauge naswona swikwirikiri swa ku leha loku faneleke swa hlawuriwa.
Loko marhambu ya tiya, ku nga tirhisiwa ku ba.
Xiyenge lexi xi hundzula matluka yo nghenisa xirho xa ku nghenisiwa eka xivumbeko xa webu lexi nga erivaleni lexi nga na makhadi ya maendlelo lama hambanisiweke na swifaniso leswi fambelanaka na swona.
Tirhisa xikurufudrayiva ku nghenisa swikwirikiri. Nghenisa hexagon ya screwdriver eka screw hiku hetiseka, kutani screw eka sleeve yo pfala ku nghenisa screw.
Tirhisa ti screw-holding forceps ku pfuneta eka ku nghenisiwa ka screw naku veka. Hi ku landzelelana nghenisa swikwirikiri leswi saleke hi ku landzelela xifaniso xa maendlelo lexi fanaka.
Hlawula ku leha ka nhonga leyi faneleke kuya hi anatomical curvature ya muvabyi. Nhonga yi tsemiwa naswona yi prebent kuya hi ku famba ka nhonga kuva yi amukela sagittal curve ya nkolo.
Ku gombonyoka ngopfu naku phindha-phindha swifanele ku papalatiwa kuva ku hlayisiwa vutshembeki bya swilo leswi vonakaka. Nhonga yifanele ku kamberiwa hi vukheta leswaku yinga onhaka loko yingase nghenisiwa.
Khoma nhonga hi ti forceps leti khomaka nhonga kutani u yi veka eka swiphemu swa xivumbeko xa U swa swikwirikiri leswi nghenisiweke.
Hi ku tirhisa xilotlelo xa preload, nghenisa pulagi ya xikurufu eka xilotlelo xa xivumbeko xa U lexi nga ni tintambhu. Ekusunguleni tiyisisa xikurufu xin’we lexi vekiweke hi xilotlelo xa hexagonal ku tiyisisa nhonga swa xinkarhana.
Endzhaku kaloko spinal rod yitshame eka ti slots ta xivumbeko xa U ta ti pedicle screws, kunga endliwa ti reduction na contouring maneuvers.
Compression: veka ti compression forceps eka ti pedicle screws letinga ekusuhi kutani u tirhisa matimba yo pfala endzeni ku koka ti vertebrae timbirhi kusuhi hiku tirhisa rod linkage.
Ku kavanyeta: veka distractor exikarhi ka swikwirikiri swimbirhi leswi nga ekusuhi na ku kavanyeta etlhelo ka nhonga ku vuyisa ku leha loku lahlekeke ka intervertebral na ku humesa timintsu ta misiha leyi tshikilelekeke.
Ku rhendzeleka: khoma nhonga hi ti rod rotators kutani u rhendzeleka na nhonga ya nkolo endzeni ka screw U-slot ku lulamisa sagittal curvature naku ringanisa swipfalo swa screw.
Hiku tirhisa sleeve ya anti-rotation, nghenisa plug ya screw eka slot ya xivumbeko xa U xa screw kutani u yi tiyisisa swa xinkarhana hi hexagonal wrench.
Khiya swikwirikiri hinkwaswo swa occipital na cervical kusuka ehenhla kuya ehansi, naswona u nghenisa swihlanganisi swa transverse tani hileswi swilaveka.
Endzhaku ko tiyisisa ku ringanisiwa loku lavekaka na xiyimo xa ku nghenisiwa, endla ku tiyisisa ko hetelela ka swikwirikiri hinkwaswo leswi vekiweke hi ku tirhisa xilotlelo lexi boxiweke xa torque-limiting.
Tiyisisa leswaku swiphemu hinkwaswo swi lotleriwile kahle naswona construct yi tshamisekile loko ku nga si pfala swilondza.
Xiya: xilotlelo lexi hungutaka torque i xitirhisiwa xo hlawula naswona xi xavisiwa hi ku hambana.
Tiyisisa ku ringanana, xiyimo xa implant, ku pfala ka xiphemu na ku tshamiseka ka construct loko kungase pfala.
Matafula lama nga laha hansi ya hundzula vuxokoxoko bya xiendliwa xa PDF ku va matafula ya webusayiti lama hlamulaka ku olova ku pfula na ku endla swikombo.
