Titanium posterior spinal fixation system ya occipitocervical, kumtunda kwa khomo lachiberekero komanso kutsika kwa khomo lachiberekero.
Titaniyamu
3.5mm ndodo yokhazikika
Screw-rod posterior fixation
Dongosololi limaperekedwa ndi njira zingapo zosinthira occipital, kapangidwe ka ndodo kocheperako ka 3.5mm, zida zomwe mungasankhe pazochita zosiyanasiyana zachipatala, komanso mawonekedwe a screw a polyaxial kuti asinthe mawonekedwe osinthika.
Njira zosiyanasiyana zokonzekera occipital zingasankhidwe malinga ndi zomwe adokotala amakonda komanso zofunikira zamilandu.
Dongosololi limagwiritsa ntchito ndodo yokhazikika ya 3.5mm yokhala ndi mapangidwe apansi apambuyo.
Zida zosankhidwa zilipo kuti zithandizire zizolowezi zosiyanasiyana zachipatala komanso zokonda zamayendedwe a opaleshoni.
Mapangidwe otsika kwambiri amathandiza kuchepetsa kukondoweza kwa minofu yofewa yozungulira kuzungulira kumanga.
Kapangidwe ka ulusi wa negative-angle kumathandiza kuti mkono wa screw usakule.
Mapangidwe apadera a polyaxial screw amathandizira kusuntha kopitilira muyeso mpaka 55 °.
Zomwe zili m'ndondomekozi zimakonzedwa ngati makhadi owoneka bwino kotero kuti zimawerengedwa bwino pa intaneti kuposa kufalikira koyambirira kwa PDF. Sungani chidziwitso chogwiritsa ntchito akatswiri pamwamba pa gawoli posindikiza.
Wodwalayo amaikidwa pamalo okhazikika monga momwe amachitira pakatikati pa khomo lachiberekero. Onetsani fupa la occipital, posterior arch of the atlas, ndi articular mass and arch of the khomo lachiberekero gawo lomwe liyenera kusakanikirana.
Pambuyo pozindikira malo olowera ndi malo olowera, fupa la cortical limakumbidwa ndi kubowola kotseguka ndipo dzenje limakulitsidwa.
Malo olowera wononga amafotokozedwa ngati mkati mpaka pakati pa tsinde lambali ndi 2mm kumtunda. Mbali yolowera imapendekera kunja kwa 20 ° -25 ° ndipo kumapeto kwamutu 30 ° -40 °, kufananiza ndi malo oyandikana nawo.
Kuyika koyenera kwa zomangira zapakhomo za C3-C7 kumathandizira kuchepetsa mtsempha wa vertebral ndi chiwopsezo cha minyewa pomwe kumapereka utali wotalikirapo komanso kukonza bwino.
Pansi pa khola lachiberekero C3-C7: malo olowera wononga ndi 2-5mm mkati mwa m'mphepete mwa chigawo cham'mbali ndi 2-3mm pansi pa tsinde la gawo lakumtunda. Mbali yolowera ndi 30 ° -45 ° mkati mwa ndege ya coronal, ndi ndege ya sagittal yofanana ndi mapeto apamwamba.
Kumtunda kwa khomo lachiberekero C1-C2: C1 lateral mass screw entry imafotokozedwa mozungulira 18-20mm pambali pakatikati pa tubercle yapambuyo ya atlas, ndi kuya kwake kumayendetsedwa pafupifupi 28mm. Kulowa kwa C2 pedicle screw kumafotokozedwa pakatikati pa mzere woyimirira pakati pa misa yotsatizana, ndikuya nthawi zambiri pafupifupi 24-26mm.
Malongosoledwe olowera wonongawa ndizomwe zili mu IFU ndipo zimatengera momwe maopaleshoni amachitikira.
Gwiritsani ntchito kubowola ndi kalozera pobowola ndikuzindikira kuya kwake komwe kukuyenera kubowoleredwa. Sinthani kalozera ku sikelo yofananira kuti muchepetse kuya.
Control pobowola liwiro ndi kuya mosamalitsa malinga ndi deta kuyeza. Lekani kubowola mwamsanga mukangofika kukuya komwe munakonzedweratu kuti mupewe kupitirira-kulowa kwa vertebral cortex ndi kuwonongeka kwa mitsempha yotumphukira kapena mitsempha ya mitsempha.
Chotsani pobowola bowo likatha ndikuyeretsa zinyalala za mafupa mkati mwa dzenje loyendetsa.
Kuzama kwa njira yopangira screw kumayesedwa ndi kuyeza kuya ndipo zomangira zautali woyenerera zimasankhidwa.
Ngati fupa ndi lolimba, kugogoda kungagwiritsidwe ntchito.
Gawoli likusintha masamba oyikapo kuti akhale omveka bwino awebusayiti okhala ndi makhadi olekanitsidwa ndi zithunzi zofananira.
Gwiritsani ntchito screwdriver kuti muyike zomangira. Lowetsani hexagon ya screwdriver mu wononga kwathunthu, kenaka potola mu mkono wokhoma kuti mutseke wononga.
Gwiritsani ntchito ma screw-holding forceps kuti muthandizire kuyika zomata ndikuyika. Lowetsani motsatizana zomangira zotsalira potsatira ndondomeko yofananira.
Sankhani kutalika kwa ndodo yoyenera malinga ndi kupindika kwa anatomical kwa wodwalayo. Ndodoyo imadulidwa ndikumangika molingana ndi kayendetsedwe ka ndodo kuti igwirizane ndi piritsi la sagittal la msana.
Kupinda kopitilira muyeso ndi mobwerezabwereza kuyenera kupewedwa kuti musunge kukhulupirika kwa zinthu. Ndodoyo iyenera kuyang'aniridwa mosamala ngati yawonongeka musanayike.
Gwirani ndodoyo ndi zomangira ndodo ndikuyiyika mu mipata yooneka ngati U ya zomangira zobzalidwa.
Pogwiritsa ntchito wrench ya preload, ikani pulagi yowononga mu kagawo ka U-shaped ulusi. Poyamba mangani sikona imodzi ya seti ndi wrench ya hexagonal kuti muteteze ndodoyo kwakanthawi.
Ndodo ya msana ikakhazikika muzitsulo zooneka ngati U za zomangira za pedicle, kuchepetsa ndi kuwongolera kozungulira kumatha kuchitika.
Kuponderezana: khazikitsani zomangira zomangira zomangirira pafupi ndi pedicle ndikuyika mphamvu yotsekera mkati kuti muyandikire ma vertebrae awiri kudzera pa ndodo.
Zosokoneza: ikani zosokoneza pakati pa zomangira ziwiri zoyandikana ndikusokoneza pandodo kuti mubwezeretse kutalika kwa intervertebral ndikumasula mizu yolimba ya minyewa.
Kuzungulira: Gwirani ndodoyo ndi ndodo zozungulira ndikuzungulira ndodo ya msana mkati mwa screw U-slot kuti musinthe kupindika kwa sagittal ndikuyanjanitsa zotsegula.
Pogwiritsa ntchito chotchinga chotchinga kuzungulira, ikani pulagi yowonongayo mu phula lokhala ngati U la zomangira ndipo mumangitse kwakanthawi ndi chikwapu cha hexagonal.
Tsekani zomangira zonse za occipital ndi khomo lachiberekero kuchokera pamwamba mpaka pansi, ndipo ikani zolumikizira zopingasa ngati pakufunika.
Mukatsimikizira kulondola komwe mukufuna ndikuyika, limbitsani zomangira zonse pogwiritsa ntchito wrench yochepetsa ma torque.
Onetsetsani kuti zigawo zonse ndi zokhoma bwino ndipo chomangacho ndi chokhazikika chilonda chisanatseke.
Zindikirani: wrench-limiting wrench ndi chowonjezera chosankha ndipo chimagulitsidwa padera.
Tsimikizirani kuyanjanitsa, malo oyikapo, kutseka kwachigawo ndikukhazikitsa bata musanatseke.
Matebulo omwe ali pansipa amasintha zambiri zamtundu wa PDF kukhala matebulo omvera patsamba kuti musakatule mosavuta ndikulondolera.
