Titanium
3.5mm tsvimbo yakagadzika
Screw-rod posterior fixation
Iyo sisitimu inounzwa neakawanda occipital kugadzirisa nzira, yakaderera-mbiri 3.5mm tsvimbo dhizaini, yakasarudzika zviridzwa zvemaitiro akasiyana ekiriniki, uye polyaxial screw chimiro che flexible kuvaka kugadzirisa.
Nzira dzakasiyana dzekugadzirisa occipital dzinogona kusarudzwa maererano nezvinodiwa nachiremba uye nyaya dzinodiwa.
Iyo sisitimu inoshandisa 3.5mm dhayamita yakagadzika tsvimbo ine yakaderera-yepamusoro-yakadzika posterior fixation kuvaka.
Optional maturusi aripo kutsigira akasiyana kiriniki maitiro uye yekuvhiya mafambiro ekufambisa.
Iyo yakaderera-yedhizaini dhizaini inobatsira kuderedza kurudziro yezvakatenderedza zvinyoro zvinyoro zvakapoteredza kuvaka.
Iyo negative-angle shinda dhizaini inobatsira kudzivirira screw ruoko kuti isakure.
Iyo yakakosha-chimiro polyaxial screw dhizaini inotsigira yakanyanya unidirectional kufamba kusvika ku55 °.
Maitiro emukati akarongwa semakadhi ekuona saka anoverenga zvirinani online pane yekutanga PDF kupararira. Chengeta chiziviso chehunyanzvi-chekushandisa pamusoro pechikamu chino paunenge uchidhinda.
Murwere anoiswa panzvimbo yakagadzikana seyepakati pepakati pekupedzisira cervical incision. Ratidza occipital bone, posterior arch yeatlas, uye articular mass uye arch yechikamu chekervical chinoda kusanganiswa.
Mushure mekusarudza nzvimbo yekupinda uye kona yekupinda, pfupa re cortical rinoputirwa nedhiri yakazaruka uye gomba rinowedzerwa.
Iyo screw yekupinda poindi inotsanangurwa semukati kune yepakati poindi yedivi rehuremu uye 2mm kumusoro. Kona yekupinda yakarerekera kunze 20°-25° uye yakananga kumucheto wemusoro 30°-40°, inofambirana nechepadivi pearticular surface.
Kuiswa kwakaringana kweyezasi cervical C3-C7 screws kunobatsira kuderedza vertebral artery uye njodzi yetsinga uku ichipa yakakura screw urefu uye yakakwana kugadzirisa.
Yezasi cervical C3-C7: iyo screw entry point ndeye 2-5mm mukati mekunze kwemupendero wepadivi block uye 2-3mm pazasi pechigadziko cheiyo articular pamusoro pechiso chepamusoro. Iyo kona yekupinda ndeye 30 ° -45 ° mukati me coronal plane, ine sagittal plane parallel to the top endplate.
Upper cervical C1-C2: C1 lateral mass screw entry inotsanangurwa yakatenderedza 18-20mm padivi pepakati peiyo posterior tubercle yeatlas, nekudzika kunodzorwa panenge 28mm. C2 pedicle screw entry inotsanangurwa nechepakati pemutsara wakatwasuka pakati pe lateral mass, nekudzika kwakawanda kungaita 24-26mm.
Iyi tsananguro yekupinda screw inyanzvi yereferensi yemukati kubva kuIFU uye zvinoenderana nemamiriro ekuvhiya chaiwo.
Shandisa chibooreso negwara pakuboora uye kuona kudzika kunofanira kucherwa. Gadzirisa gwara kune chikero chinowirirana kuti udzikise kudzika.
Kudzora kumhanya kuchera nekudzika kwakanyatso kuenderana neyakayerwa data. Rega kuchera pakarepo kana wasvika pakadzika kwakatemwa kuti udzivise kupinda-kupfuura kwevertebral cortex uye kukuvadzwa kune peripheral nerve kana vascular tissue.
Bvisa chibooreso mushure mekunge gomba rapera uye chenesa marara emapfupa mukati megomba rekutyaira.
Kudzika kwescrew nzira inoyerwa nejeji yehupamhi uye screws dzehurefu hwakakodzera dzinosarudzwa.
Kana pfupa rakaoma, kubata kunogona kushandiswa.
Ichi chikamu chinoshandura mapeji ekuisa ekudyara kuita chimiro chakajeka chewebhu chine makadhi emaitiro akapatsanurwa uye mifananidzo inoenderana.
Shandisa screwdriver kuisa screws. Isa hexagon yescrewdriver musiruu zvachose, wobva wapukuta muruzha rekukiya kuti uise sikuruu.
Shandisa screw-holding forceps kubatsira mukupinza nekugadzika. Sequentially isa screws asara uchitevera zvakafanana procedural template.
Sarudza urefu hwakakodzera hwetsvimbo maererano neanatomical curvature yemurwere. Tsvimbo inochekwa uye prebent maererano nekufamba kwetsvimbo kuti igare sagittal curve yemuzongoza.
Kupeta kwakanyanyisa uye kudzokororwa kunofanira kudziviswa kuchengetedza kuvimbika kwezvinhu. Tsvimbo inofanira kunyatsotariswa kuti haina kukanganisa isati yaiswa.
Bata tsvimbo ine tsvimbo-inobata simba uye uiise muU-shaped slots yezviputi zvakasimwa.
Uchishandisa preload wrench, isa screw plug muU-shaped threaded slot. Tanga sunga siruu imwe chete nechipanera chine hexagonal kuchengetedza tsvimbo nguva.
Mushure mekunge musana wemuzongoza wakagara mukati meU-shaped slots ye pedicle screws, kuderedza uye contouring maneuvers inogona kuitwa.
Kudzvanya: gomo compression forceps pane yakatarisana pedicle screws uye isa mukati mekuvhara simba kuswededza maviri vertebrae pedyo kuburikidza netsvimbo yekubatanidza.
Kuvhiringidza: isa distractor pakati pemasikiru maviri ari padyo uye kanganisa padivi petsvimbo kuti udzore yakarasika intervertebral kureba uye kusunungura yakamanikidzwa tsinga midzi.
Kutenderera: bata tsvimbo netsvimbo inotenderera uye tenderedza spinal rod mukati me screw U-slot kugadzirisa sagittal curvature uye gadzirisa screw kuvhurwa.
Uchishandisa sleeve yekudzivirira kutenderera, isa screw plug mu-U-shaped slot ye screw woisunga kwenguva nechipanera chine hexagonal.
Kiya ese occipital uye cervical screws kubva kumusoro kusvika kuzasi, uye kudyara zvinochinjika zvinobatanidza sezvinodiwa.
Mushure mekusimbisa kurongeka kwaunoda uye kuisirwa chinzvimbo, ita kuomesa kwekupedzisira kwese kuseta screws uchishandisa yakatsanangurwa torque-yekumisa wrench.
Wona kuti zvikamu zvese zvakakiyiwa zvakachengeteka uye chivakwa chakagadzikana chisati chavharwa ronda.
Ongorora: iyo torque-yekumisikidza wrench ndeye sarudzo yekuwedzera uye inotengeswa zvakasiyana.
Simbisa kurongeka, kuisa chinzvimbo, kukiya chikamu uye kuvaka kugadzikana kusati kwavharwa.
Matafura ari pazasi anoshandura ruzivo rwechigadzirwa chePDF kuita matafura ewebhusaiti anoteerera kuitira nyore kubhurawuza uye indexing.
