3.5mm induku engashintshi
Ukulungiswa kwe-screw-rod posterior
Uhlelo lwethulwa ngezindlela eziningi zokulungisa i-occipital, idizayini yenduku engu-3.5mm enephrofayili ephansi, amathuluzi angakhethwa emikhuba ehlukene yomtholampilo, kanye nesakhiwo sesikulufu se-polyaxial sokulungiswa okuguquguqukayo kokwakha.
Izindlela ezihlukene zokulungisa i-occipital zingakhethwa ngokuvumelana nokukhethwa kodokotela ohlinzayo kanye nezidingo zecala.
Isistimu isebenzisa induku egxilile engu-3.5mm enokwakheka kokulungisa okungemuva kwephrofayela ephansi.
Amathuluzi ongawakhetha ayatholakala ukusekela imikhuba yomtholampilo eyahlukene kanye nezintandokazi zokuhamba komsebenzi wokuhlinza.
Idizayini yephrofayili ephansi isiza ukunciphisa ukukhuthazwa kwezicubu ezithambile ezizungezile ezizungeze ukwakhiwa.
Idizayini yentambo ye-engeli eyinegethivu isiza ukuvimbela ingalo yesikulufu ukuthi ingakhuli.
Idizayini yesikulufu esikhethekile se-polyaxial isekela ukunyakaza okuphezulu okungaqondile okungafika ku-55°.
Okuqukethwe kwenqubo kuhlelwa njengamakhadi abonakalayo ngakho kufundeka kangcono ku-inthanethi kunokusatshalaliswa kwe-PDF kwasekuqaleni. Gcina isaziso sokusetshenziswa kochwepheshe ngaphezu kwalesi sigaba lapho ushicilela.
Isiguli sibekwe endaweni ethambekele njengokusikwa komlomo wesibeletho okuphakathi komugqa omaphakathi. Veza ithambo le-occipital, i-posterior arch ye-atlas, kanye nesisindo se-articular ne-arch yengxenye yomlomo wesibeletho okudingeka ihlanganiswe.
Ngemva kokunquma indawo yokungena kanye ne-angle yokungena, ithambo le-cortical libhobozwa nge-drill evulekile futhi imbobo iyakhuliswa.
Iphoyinti lokungena ngezikulufu lichazwa njengelingaphakathi endaweni ephakathi nendawo yesisindo eseceleni no-2mm phezulu. I-engeli yokungena itshekele ngaphandle ngo-20°-25° futhi ngasemaphethelweni ekhanda angu-30°-40°, ngokuhambisana nendawo eseduze ye-articular.
Ukubekwa kahle kwezikulufu ezingezansi zomlomo wesibeletho ze-C3-C7 kusiza ukunciphisa umthambo womgogodla kanye nobungozi bezinzwa kuyilapho kunikeza ubude bezikulufu obukhulu kanye nokulungisa kahle.
I-C3-C7 yomlomo wesibeletho ephansi: indawo yokungena yesikulufu ingu-2-5mm ngaphakathi konqenqema olungaphandle lwebhulokhi eseceleni kanye no-2-3mm ngaphansi kwesisekelo sendawo engaphezulu ye-articular of the facet engenhla. I-engeli yokungena ingu-30°-45° ngaphakathi kwendiza ye-coronal, indiza ye-sagittal ihambisana ne-endplate engenhla.
I-C1-C2 yomlomo wesibeletho engenhla: I-C1 lateral mass screw entry ichazwa cishe ngo-18-20mm eceleni kwendawo emaphakathi ye-tubercle yangemuva ye-atlas, ngokujula okulawulwa cishe ku-28mm. I-C2 pedicle screw entry ichazwa endaweni emaphakathi yomugqa oqondile maphakathi nesisindo esingemuva, ngokujula ngokuvamile okungaba ngu-24-26mm.
Lezi zincazelo zokungena ngezikulufo zingokuqukethwe okuyireferensi kochwepheshe okuvela ku-IFU futhi kuncike esimweni esithile sokuhlinzwa.
Sebenzisa i-drill bit nomhlahlandlela ukuze ubhoboze futhi unqume ukujula okuzobhojwa. Lungisa umhlahlandlela esikalini esihambelanayo ukuze ukhawulele ukujula.
Lawula isivinini sokubhola nokujula ngokuqinile ngokwedatha elinganisiwe. Misa ukubhoboza ngokushesha lapho ufinyelela ekujuleni okunqunywe kusengaphambili ukuze ugweme ukungena ngokweqile kwe-vertebral cortex kanye nokulimala kwe-peripheral nerve noma izicubu ze-vascular.
Susa i-drill bit ngemva kokuphela kwembobo futhi uhlanze imfucumfucu yamathambo ngaphakathi kwembobo yokuhlola.
Ukujula kwendlela yesikulufu kukalwa ngegeji yokujula bese kukhethwa izikulufu ezinobude obufanele.
Uma ithambo liqinile, ukuthepha kungasetshenziswa.
Lesi sigaba siguqula amakhasi okufaka okufakwayo abe isakhiwo sewebhu esicacile esinamakhadi enqubo ahlukene kanye nemifanekiso ehlobene.
Sebenzisa i-screwdriver ukufaka izikulufu. Faka i-hexagon ye-screwdriver esikulufini ngokuphelele, bese ugoqa kumkhono wokukhiya ukuze ugxilise isikulufu.
Sebenzisa i-screw-hold forceps ukusiza ukufaka isikulufu nokubeka indawo. Faka ngokulandelana izikulufu ezisele ngokulandela isifanekiso senqubo esifanayo.
Khetha ubude benduku obufanele ngokuya ngokugoqeka kwe-anatomical kwesiguli. Induku iyasikwa futhi i-prebent ngokuvumelana nokunyakaza kwenduku ukuze kufakwe ijika le-sagittal lomgogodla.
Ukugoba okudlulele nokuphindaphindiwe kufanele kugwenywe ukuze kugcinwe ubuqotho bezinto ezibonakalayo. Induku kufanele ibhekwe ngokucophelela ukuthi ayinamonakalo yini ngaphambi kokufakwa.
Bamba induku enama-forceps abambe induku bese uyibeka ezindaweni ezimise okuka-U zezikulufu ezifakiwe.
Usebenzisa i-wrench yokulayisha kuqala, faka ipulaki yesikulufu endaweni enentambo emise okuka-U. Ekuqaleni qinisa isikulufu sesethi esisodwa ngesikrufu esine-hexagonal ukuze uvikele induku okwesikhashana.
Ngemva kokuba induku yomgogodla ihlezi ezindaweni ezimise okwe-U zezikulufu ze-pedicle, ukuqondisa okuncishiswayo kanye ne-contouring kungenziwa.
Ukucindezelwa: faka ama-compression forceps kuzikulufu eziseduze ze-pedicle bese usebenzisa amandla okuvala angaphakathi ukuze usondele ama-vertebrae amabili ngokuxhuma induku.
Isiphazamisi: faka isiphazamisi phakathi kwezikulufu ezimbili eziseduze futhi uphazamise eduze kwenduku ukuze ubuyisele ubude be-intervertebral elahlekile futhi ukhulule izimpande zezinzwa ezicindezelwe.
Ukuzungezisa: bamba induku ngama-rod rotator bese uzungezisa induku yomgogodla ngaphakathi kwesikulufu se-U-slot ukuze ulungise i-sagittal curvature futhi uqondanise izikhala zokuvuleka.
Usebenzisa umkhono ovimbela ukuzungezisa, faka ipulaki yesikulufu endaweni yesikulufu esimise okuka-U futhi usiqinise okwesikhashana ngesikrufu esiyi-hexagonal.
Khiya zonke izikulufu ze-occipital nezomlomo wesibeletho ukusuka phezulu kuye phansi, bese ufaka izixhumi eziphambanayo njengoba kudingeka.
Ngemva kokuqinisekisa ukuqondanisa okufunayo kanye nesimo sokufakelwa, yenza ukuqinisa kokugcina kwazo zonke izikulufu ezisethiwe usebenzisa isikrufu esinqunyiwe se-torque esicacisiwe.
Qinisekisa ukuthi zonke izingxenye zikhiywe ngokuvikelekile futhi ukwakhiwa kuzinzile ngaphambi kokuvalwa kwenxeba.
Qaphela: i-torque-limiting wrench iyisetshenziswa ozikhethela sona futhi sithengiswa ngokuhlukana.
Qinisekisa ukuqondanisa, indawo yokufakelwa, ukukhiya ingxenye futhi wakhe ukuzinza ngaphambi kokuvalwa.
Amathebula angezansi aguqula imininingwane yomkhiqizo we-PDF ibe amathebula ewebhusayithi aphendulayo ukuze kube lula ukuphequlula nokufaka ohlwini.
