1.Dynamic Skull (DHS)
Kuphulika kwa chiuno pakati pa ma tuberosities - DHS yolimbitsa msana:
★DHS mphamvu nyongolotsi ubwino waukulu:
Kukonzekera kwamkati mkati mwa fupa la m'chiuno kumakhala ndi mphamvu yamphamvu, ndipo kungagwiritsidwe ntchito moyenera pamene fupa limagwiritsidwa ntchito nthawi yomweyo.
Makina otsetsereka a in-cylinder amatha kupewedwa kuphulika kwa fupa la m'chiuno kapena molar, mphamvu yokoka yoyipa imatsogolera ku fupa.
Mphamvu yotsetsereka posungira chipangizo chophwanyika ndikuyikanso, kuwonongeka kochepa.
Compressive ndi kutsetsereka kuwirikiza kawiri, ndi yogwira static kuthamanga kanthu.
★ Zofooka za sitima yamagetsi ya DHS:
Kulephera odana ndi kasinthasintha luso, pambuyo mwachizolowezi clenched nsapato kapena polima kunja fixation.
Pakati periosteum yawonongeka kwambiri, kufalikira kwa minofu, kupasuka kwa kupereka magazi, ndipo kafukufuku anapeza kuti fupa linakhazikika mu chigaza, ndipo fupa linawonongeka kwambiri.
Panthawi yokonza, pamakhala chiwombankhanga pansi pa kutseguka, kuwonongeka kwa tsamba kumakhala koopsa, zitsulo zopangira mutu zimakhala zovuta, m'mimba mwake ndi pafupifupi 15mm, ndipo sizingatheke kutsegula kangapo.
Ngodyayo imakhazikika pa madigiri 130 kapena madigiri 135, ndipo mbali yeniyeni ya wodwalayo imasinthidwa moyenerera.
2. Zida Zamphamvu (DCS)
Kuthyoka kwa Mchiuno-Kukonza DCS:
DCS kuchuluka kwa 95-degree incision steel plate-contraction reflex fracture:
★Ubwino Wachikulu wa DCS Kinky Dragon:
N'zotheka kusankha malo oyenerera olowera muzu, ndi njira ya opaleshoni.
Mphamvu yomwe imagwiritsidwa ntchito pazitsulo zachitsulo ili pafupi ndi ngodya yoyenera, ndi zofunikira za biomechanical za msana wofanana.Pansi pa katundu wolemetsa, mphamvu yokoka imagwiritsidwa ntchito pa khosi la mbale yachitsulo, ndiyeno imagawidwanso ku screw iliyonse, kupanikizika kumagawidwa, ndipo kukonza kumakhala kolimba nthawi zonse.
Chiwerengero chochepa cha DCS spiral fractures, kuwonjezereka kolimba, kukonza pa malo ophwanyidwa, ndi chiwerengero chochepa cha zochitika pambuyo pake.
3.Proximal hip bone pin (PFN)
Kuphulika kwa chiuno pakati pa ma tuberosities-PFN fixation:
★PFN zokhazikika:
Kutalika kwa thupi ndi kochepa kwambiri (nthawi zambiri 9mm), ndipo sikutheka kuyikapo.(Nsonga yabwino kwambiri ya Gamma——17mm)
Mapeto oyandikira a PFN ali ndi mbali yakunja pafupifupi madigiri a 6, ngodya yakunja imachepetsedwa, ndipo palibe mphamvu yamkati yamkati ikakoka.
Mapeto apamwamba amatha kuikidwa mu fupa la chiuno ndi ma spirals awiri, kuwonjezeka kwa anti-rotation spirals, mano awiri mkati mwa fupa la m'chiuno, ndikuwonjezera mphamvu zotsutsana ndi kutopa.
Chophimba chakutali ndi chinsinsi chachikulu (kutalika kwautali) ndizotalikirana, ndipo kupanikizika kwa fupa la chiuno kumatha kuchepetsedwa.
★ PFN yokhazikika zolakwika:
Pali vuto linalake ndi kuyika koyenera kofanana kwa amayi awiri a ngale kumbali ya fupa la m'chiuno, makamaka ngati ndinu wamfupi komanso wamng'ono, fupa la m'chiuno ndi lalifupi kwambiri, ndipo mayi wachikulire, muyenera kugwiritsa ntchito izi. fupa la mchiuno.6.5mm ulusi wa helical), malo a leash amasinthidwa nthawi zonse panthawi yogwiritsira ntchito mwamsanga, ndipo panthawi yokonzekera kwenikweni, kulondola koyambirira kungathe kutayika.Kutha kusunga nthawi imodzi ndi vuto lalikulu.Kuonjezera apo, pali chiopsezo cha fupa la crumpling, lomwe limatsagana ndi kuchepa kwa mafupa mosavuta chifukwa cha mizu iwiri ya spiral yamphamvu.
Chifukwa cha PFN, arc ndi yayikulu, ndipo ndi yayitali kwambiri.kusweka.Chifukwa cha kusintha kumeneku, malo a mkati mwa chiberekero ndi olondola, ndipo kotekisi pafupi ndi chingwe chakunja chamkati chamkati chamkati chimakhala mosakayikira.
Kuchuluka kwa ma radiation, kukwera mtengo kwa zida zopangira opaleshoni, komanso kufunikira kwa luso la opaleshoni.
