Inkqubo yokulungiswa komgogodla we-titanium emva kwe-occipitocervical, i-cervical ephezulu kunye ne-low cervical stabilization applications.
I-Titanium
3.5mm intonga esisigxina
Ukulungiswa kwe-Screw-rod ngasemva
Inkqubo inikezelwa ngeendlela ezininzi zokulungisa i-occipital, i-design-low-profile ye-3.5mm yentonga, izixhobo ezikhethiweyo kwimikhwa eyahlukeneyo yeklinikhi, kunye nesakhiwo se-polyaxial screw ukwenzela ukulungiswa kolwakhiwo oluguquguqukayo.
Iindlela ezahlukeneyo zokulungisa i-occipital zingakhethwa ngokukhetha ugqirha kunye neemfuno zecala.
Inkqubo isebenzisa intonga esisigxina ye-3.5mm ububanzi kunye neprofayili ephantsi yokwakhiwa kokulungiswa kwangasemva.
Izixhobo ezikhethiweyo ziyafumaneka ukuxhasa imikhwa eyahlukeneyo yeklinikhi kunye nokhetho lokuhamba komsebenzi wotyando.
Uyilo olusezantsi lunceda ukunciphisa ukuvuselela kwezicubu ezithambileyo ezijikelezayo malunga nokwakhiwa.
Uyilo lwentambo ye-negative-engile inceda ukuthintela ingalo yesikrufu ekwandeni.
Uyilo olukhethekileyo lwe-polyaxial screw luxhasa intshukumo ephezulu ye-unidirectional ukuya kuthi ga kwi-55 °.
Umxholo wenkqubo ucwangciswe njengamakhadi abonakalayo ngoko ke ufundeka ngcono kwi-intanethi kunokusasazwa kwePDF yantlandlolo. Gcina isaziso sokusetyenziswa kobuchule ngentla kweli candelo xa upapasha.
Isigulana sibekwe kwindawo elungeleleneyo njengomgangatho ophakathi komgca womlomo wesibeleko. Veza ithambo le-occipital, i-posterior arch ye-atlas, kunye nobunzima be-articular kunye ne-arch yecandelo lomlomo wesibeleko esifuna ukuxutywa.
Emva kokumisela indawo yokungena kunye ne-angle yokungena, ithambo le-cortical liqhutywe nge-drill evulekile kwaye umngxuma uyandiswa.
Indawo yokungena yesikrufu ichazwa njengengaphakathi ukuya kwindawo ephakathi yobunzima becala kunye ne-2mm ukuya phezulu. I-angle yokungena ihlanjululwe ngaphandle kwe-20 ° -25 ° kwaye ukuya ekupheleni kwentloko 30 ° -40 °, ihambelana nomphezulu we-articular okufutshane.
Ukubekwa ngokufanelekileyo kwezikrufu ezisezantsi zeC3-C7 zomlomo wesibeleko kunceda ukunciphisa umthambo we-vertebral kunye nomngcipheko we-nerve ngelixa unikezela ubude be-screw kunye nokulungiswa okufanelekileyo.
I-C3-C7 yomlomo wesibeleko esezantsi: i-screw entry point yi-2-5mm ngaphakathi komda wangaphandle webhloko yecala kunye ne-2-3mm ngaphantsi kwesiseko se-articular surface ye-facet ephezulu. I-angle yokungena i-30 ° -45 ° ngaphakathi kwendiza ye-coronal, kunye ne-sagittal plane ehambelana ne-endplate ephezulu.
I-C1-C2 yomlomo wesibeleko ephezulu: I-C1 i-screw lateral mass entry ichazwa malunga ne-18-20mm ecaleni kwe-midpoint ye-tubercle yangasemva ye-atlas, kunye nobunzulu obulawulwa malunga ne-28mm. I-C2 pedicle screw entry ichazwe kwi-midpoint yomgca othe nkqo phakathi kobunzima becala, ngobunzulu ngokubanzi malunga ne-24-26mm.
Ezi nkcazo zokungena ngezikrufu zingumxholo wereferensi yobungcali evela kwi-IFU kwaye ixhomekeke kwimeko ethile yotyando.
Sebenzisa i-drill bit kunye nesikhokelo sokugrumba kunye nokumisela ubunzulu bokwembiwa. Lungisa isikhokelo kwisikali esihambelanayo ukunciphisa ubunzulu.
Lawula isantya sokomba kunye nobunzulu ngokungqongqo ngokwedatha elinganisiweyo. Yeka ukugrumba ngokukhawuleza xa ufikelela kubunzulu obumiselwe kwangaphambili ukuze ugweme ukungena ngokugqithisileyo kwe-vertebral cortex kunye nomonakalo kwi-nerve ye-peripheral okanye i-vascular tissue.
Susa i-drill bit emva kokuba umngxuma ugqityiwe kwaye ucoce inkunkuma yamathambo ngaphakathi komngxuma wokulingwa.
Ubunzulu bendlela ye-screw bulinganiswa ngegeyiji yobunzulu kunye nezikrufu zobude obufanelekileyo zikhethiwe.
Ukuba ithambo liqinile, ukucofa kungasetyenziswa.
Eli candelo liguqula amaphepha ofakelo lofakelo abe luyilo lwewebhu olucacileyo olunamakhadi enkqubo ahlukeneyo kunye nemifanekiso enxulumeneyo.
Sebenzisa i-screwdriver ukufaka izikrufu. Faka ihexagon yesikrudrayiva kwisikrufu ngokupheleleyo, emva koko usijije kwisikhonkwane sokutshixa ukuze ufakele isikrufu.
Sebenzisa izikhonkwane zokubamba izikrufu ukunceda ukufaka isikrufu kunye nokubeka indawo. Faka ngokulandelelana izikrufu ezishiyekileyo ngokulandela itemplate yenkqubo efanayo.
Khetha ubude bentonga efanelekileyo ngokuhambelana ne-anatomical curvature yesigulane. Intonga iyasikwa kwaye i-prebent ngokwentshukumo yentonga ukulungiselela igophe le-sagittal lomqolo.
Ukugoba okugqithisileyo kunye nokuphindaphindiweyo kufuneka kugwenywe ukugcina ingqibelelo yezinto eziphathekayo. Intonga kufuneka iqwalaselwe ngononophelo ukuba akukho monakalo na phambi kokufakwa.
Bamba intonga kunye ne-forceps yokubamba intonga kwaye uyibeke kwiindawo zokubeka ezibunjwa ngu-U zezikrufu ezifakelweyo.
Usebenzisa isitshixo sokulayisha kwangaphambili, faka iplagi ejijwayo kwindawo enemisonto ye-U. Okokuqala qinisa iseti esinye isikrufu ngesikrufu esinehexagonal ukukhusela intonga okwethutyana.
Emva kokuba intonga yomgogodla ihleli kwi-slots e-U-shaped screws ye-pedicle, ukunciphisa kunye nokuguqulwa kwe-contouring kungenziwa.
Uxinzelelo: nyusa amandla oxinzelelo kwizikrufu ezikufutshane ze-pedicle kwaye usebenzise amandla angaphakathi okuvala ukusondeza ama-vertebrae amabini ngokudibanisa intonga.
Isiphazamiso: faka isiphazamisi phakathi kwezikrufu ezibini ezikufutshane kwaye uphazamise ecaleni kwentonga ukubuyisela ubude obulahlekileyo be-intervertebral kunye nokukhulula iingcambu zemithambo-luvo.
Ukujikeleza: bamba intonga kunye ne-rod rotators kwaye ujikeleze intonga yomgogodla ngaphakathi kwe-screw U-slot ukulungelelanisa i-sagittal curvature kunye nokulungelelanisa ukuvuleka kwe-screw.
Usebenzisa umkhono wokunqanda ukujikelezisa, faka iplagi yescrew kwisithuba esimilo ka-U sesikrufu kwaye usiqinise okwethutyana ngesikrufu esinehexagonal.
Tshixa zonke izikrufu ze-occipital kunye nomlomo wesibeleko ukusuka phezulu ukuya ezantsi, kwaye ufakele izihlanganisi ezinqamlezileyo njengoko kufuneka.
Emva kokuqinisekisa ulungelelwaniso olufunwayo kunye nendawo yokufakelwa, yenza ukuqina kokugqibela kwazo zonke izikrufu ezisetyenzisiweyo usebenzisa i-wrench echaziweyo yokunciphisa i-torque.
Qinisekisa ukuba onke amacandelo atshixiwe ngokukhuselekileyo kwaye ulwakhiwo luzinzile phambi kokuvalwa kwenxeba.
Qaphela: i-torque-limiting wrench yi-accessory yokuzikhethela kwaye ithengiswa ngokwahlukileyo.
Qinisekisa ukulungelelaniswa, indawo yokufakelwa, ukutshixa icandelo kunye nokwakha uzinzo phambi kokuvalwa.
Iitheyibhile ezingezantsi ziguqula ulwazi lwemveliso yePDF zibe ziitafile zewebhusayithi eziphendulayo ukuze kube lula ukubrawuza kunye nesalathiso.
