xauv maxillofacial mini duab plaub phaj

Xauv phaj yog lub pob txha fixation ntaus ntawv nrog lub xauv threaded lub qhov.Lub xauv phaj tso cai rau cov pob txha kom ruaj khov rau lub phaj, ua rau lub caj dab amputated ruaj khov tom qab repositioning.

Xauv daim hlau tau siv thawj zaug 20 xyoo dhau los hauv kev phais txha caj qaum thiab maxillofacial kom ruaj khov pob txha thaum txo qis cov nqaij mos muag thiab raug mob.

Lub phaj xauv yog lub pob txha fixation ntaus ntawv nrog threaded qhov nyob rau hauv uas lub phaj ua raws li lub kaum fixation ntaus ntawv thaum ib tug ntsia hlau nrog ib tug threaded lub taub hau yog muab tso rau. Ob leeg locking thiab tsis-locking qhov yuav muab rau txawv ntsia hlau insertion.Txhua lub phaj uas yuav tsum tau screwed rau hauv ib tug ruaj (ruaj khov) Lub kaum ntse ntse los yog ntsia liaj qhov rooj yog qhov tseem ceeb ntawm cov pob txha ntawm lub phaj tsis fixation. kev sib txuas, tab sis tag nrho yog nyob ntawm cov qauv xauv ntawm cov hlau phaj nws tus kheej.Ib qhov sib txawv ntawm cov hlau phaj thiab cov pob txha saum npoo, uas tshem tawm qhov cuam tshuam ntawm kev sib cuag hnyav ntawm cov phaj steel thiab cov pob txha, thiab zoo heev txhim kho cov ntshav txaus thiab kev loj hlob thiab rov zoo ntawm periosteum.Lub ntsiab biomechanical sib txawv ntawm cov tsoos steel phaj thiab tsoos steel phaj yog tias cov pob txha tom kawg ntawm cov pob txha.

Cov ntsia hlau xauv yog tus kheej tapping ntsia hlau thiab tuaj yeem siv yam tsis muaj tapping lossis pob txha laum.Nws tsis muaj qhov siab ntawm cov phaj hlau thiab cov pob txha cortex, yog li tsis muaj lub siab ntawm periosteum, thiaj li tiv thaiv cov ntshav ntawm periosteum.Raws li cov txheej txheem phais, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm tsis tshua muaj kev cuam tshuam, thiab tuaj yeem tiv thaiv cov pob txha hauv zos. xav tau.Lub sab hauv fixation scaffold yog elastic. Nyob rau hauv lub xub ntiag ntawm load, muaj kev ntxhov siab stimulation ntawm cov pob txha pob txha, uas yog conducive rau callus tsim thiab pob txha kho.

Tom qab maxillofacial tawg, nws yog tsuas yog txo thiab fixation.Lub cim tseem ceeb ntawm lub puab tsaig pob txha txo yog kom rov zoo li qub occlusal kev sib raug zoo ntawm cov hniav sab sauv thiab sab qis, uas yog, nws kim heev kev sib raug zoo ntawm cov hniav.Lwm yam nws yuav cuam tshuam qhov rov qab ntawm mastication muaj nuj nqi tom qab puas ntsoog kho.Muaj peb hom kev pib dua:

1.Manipulative txo: nyob rau theem pib ntawm lub puab tsaig tawg, ntu tawg yog qhov ua haujlwm zoo, thiab cov ntu tawg tuaj yeem rov qab mus rau qhov qub ntawm tes.

2.Traction txo: tom qab lub puab tsaig ntawm lub puab tsaig, tom qab lub sij hawm ntev (ntau tshaj peb lub lis piam ntawm maxilla, ntau tshaj plaub lub lis piam ntawm mandible), lub pob txha tawg muaj ib feem ntawm cov ntaub so ntswg kho, phau ntawv txo qis tsis ua tiav, traction txo txoj kev siv tau.The mandibular fracture multi-purpose lub puab tsaig traction, yog nyob rau hauv qhov chaw ntawm cov pob txha. ntawm subsection kho hniav arch splint, thiab tom qab ntawd nruab nrab ntawm cov hniav arch splint thiab lub maxillary, nrog ib tug me me roj hmab band rau elastic traction, kom nws maj mam rov zoo li qub occlusal kev sib raug zoo.Tom qab maxillary fracture, yog hais tias lub fracture segment hloov rov qab, cov hniav arch splint yuav tsum tau muab tso rau ntawm ib tug plaster thiab maxillary bracket. ntawm lub taub hau. Lub elastic traction tuaj yeem ua rau nruab nrab ntawm cov hniav arch splint thiab hlau bracket, kom cov maxillary fracture ntu tuaj yeem rov qab los rau pem hauv ntej. Kab rov tav lub ntiajteb txawj nqus traction kuj tseem siv tau thaum xav tau lub zog loj traction.

3.Open txo: Cov lus qhia rau kev txo qis yog qhov dav.Open yuav tsum tau ua thaum cov pob txha tawg tau hloov mus rau lub sijhawm ntev thiab muaj fibrous kho los yog pob txha malalignment kho, thiab qhov txo qis tsis tuaj yeem ua tiav los ntawm kev tswj hwm lossis traction.Cov ntaub so ntswg tsim nyob rau hauv lub dislocation tawg los yog exfoliation ntawm lub exlocation. chiseled tam sim ntawd, thiab lub puab tsaig yog rov qab txiav rov qab mus rau nws txoj hauj lwm qub.Open txo feem ntau yog siv rau cov pob txha tshiab los yog qhib pob txha uas muaj teeb meem hauv phau ntawv txo lossis tsis ruaj khov tom qab txo.
