Locking Screw: Kumvetsetsa Ntchito Yake ndi Kufunika Kwake
Pankhani ya opaleshoni ya mafupa, kugwiritsa ntchito zomangira zotsekera ndizofunikira kuti mafupa apangidwe bwino. Zomangira izi zidapangidwa kuti zizitha kukhazikika pakati pa fupa ndi implant, kuteteza kusuntha kulikonse ndikulola kuchira bwino. M'nkhaniyi, tiwona ntchito ndi kufunikira kwa zomangira zotsekera, momwe zimagwirira ntchito, ndi mitundu yosiyanasiyana yomwe ilipo.
Kodi Locking Screw ndi chiyani?
Chophimba chotsekera ndi mtundu wa wononga fupa lomwe limapangidwa kuti litseke choyikapo ndi fupa palimodzi, kupereka kukhazikika kokhazikika komanso kotetezeka. Mosiyana ndi zomangira zachikhalidwe, zomwe zimadalira ulusi wa screw kuti ugwire fupa pamalo ake, zomangira zotsekera zimapangidwa kuti zitseke mutu wa screw ku implant, kulola kulumikizana kolimba kwambiri.
Kodi Zotsekera Zimagwira Ntchito Bwanji?
Zomangira zotsekera zimagwira ntchito popanga kulumikizana kosakhazikika pakati pa fupa ndi implant. Mutu wa screw umapangidwa kuti ugwirizane ndi makina otsekera pa implant, zomwe zimalepheretsa kuyenda kulikonse. Kukonzekera kolimba kumeneku kumathandizira kuchiritsa koyenera komanso kumachepetsa chiopsezo cha kulephera kwa implant.
Kufunika Kotsekera Zomangira
Kugwiritsa ntchito zomangira zotsekera ndikofunikira pakuchita opaleshoni ya mafupa pazifukwa zingapo. Choyamba, amapereka kukhazikika kokhazikika komanso kotetezeka, kulola machiritso abwino komanso kuchepetsa chiopsezo cha kulephera kwa implant. Kuonjezera apo, zomangira zotsekera zimakhala zothandiza makamaka kwa odwala omwe ali ndi mafupa osauka kapena omwe akuvutika maganizo kwambiri, chifukwa amatha kupereka chithandizo chowonjezereka ndi kukhazikika.
Mitundu ya Zokhoma Zokhoma
Pali mitundu ingapo ya zomangira zokhoma zomwe zilipo, iliyonse ili ndi kapangidwe kake ndi ntchito yake. Mitundu ina yodziwika bwino ndi:
Cannulated Locking Screws
Zomangira zotsekera zam'kanizi zimapangidwa ndi pakati, zomwe zimalola kuyika waya wowongolera. Zomangira zamtunduwu ndizothandiza makamaka pamachitidwe omwe amafunikira kuyika bwino, popeza waya wowongolera atha kugwiritsidwa ntchito kutsimikizira malo olondola.
Zotsekera Zolimba
Zomangira zokhoma zolimba zimapangidwa ndi phata lolimba, zomwe zimapereka mphamvu zowonjezera komanso kukhazikika. Mtundu woterewu nthawi zambiri umagwiritsidwa ntchito m'njira zomwe zimafuna chithandizo chowonjezera, monga kuphatikizika kwa msana kapena kukonza fracture.
Zosintha Zosiyanasiyana za Angle Locking
Zomangira zotsekera zosinthika zimapangidwira kuti zizitha kuyenda mosiyanasiyana, zomwe zimapangitsa kuti pakhale kukhazikika komanso kukhazikika. Mtundu uwu wa screw nthawi zambiri umagwiritsidwa ntchito m'njira zomwe zimaphatikizapo fractures zovuta kapena kupunduka.
Njira Yoyikira Zokhoma Zokhoma
Njira yolowetsa zomangira zotsekera imayamba ndikupanga dzenje loyendetsa ndege, kenako ndikuyika waya wowongolera. Waya wolondolerayo ukakhazikika, zotsekera zotsekera zimatha kuyikidwa pamwamba pa waya ndikutetezedwa pamalo ake. Njira yotsekera pa implant imapangidwa, ndikupanga kulumikizana kolimba pakati pa fupa ndi implant.
Zovuta Zomwe Zingachitike
Ngakhale zomangira zotsekera nthawi zambiri zimakhala zotetezeka komanso zothandiza, pali zovuta zomwe zingachitike. Izi zingaphatikizepo kuthyoka kwa screw, kumasula zomangira, ndi kusamuka kwa screw. Kuonjezera apo, kuyika kapena kuyika kosayenera kungayambitse kuwonongeka kwa fupa kapena minofu yozungulira.
Mapeto
Pomaliza, zomangira zotsekera zimagwira ntchito yofunika kwambiri pakuchita opaleshoni ya mafupa, kupereka kukhazikika kokhazikika komanso kotetezeka pakati pa fupa ndi implant. Kumvetsetsa ntchito yawo ndi kufunikira kwawo ndikofunikira kwa onse opaleshoni ndi odwala omwe, chifukwa angathandize kuonetsetsa kuti machiritso abwino ndi kuchepetsa chiopsezo cha kulephera kwa implant.
