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 taub hau yog muab tso rau.Ob lub xauv thiab tsis-locking qhov yuav muab rau txawv ntsia hlau insertion.Txhua lub phaj uas muaj peev xwm. yuav tsum tau ntsia hlau rau hauv ib qho ruaj khov (ruaj khov) Lub kaum ntse ntse los yog ntsia liaj qhov rooj yog qhov tseem ceeb ntawm lub phaj xauv.Qhov kev kho ntawm cov phaj hlau tsis yog nyob ntawm cov pob txha kev sib txhuam kom paub qhov kev sib txuas, tab sis tag nrho yog nyob ntawm cov qauv xauv ntawm cov phaj steel nws tus kheej.A Qee qhov sib txawv tuaj yeem sab laug ntawm cov phaj hlau thiab cov pob txha pob txha, uas tshem tawm qhov cuam tshuam ntawm kev sib cuag hnyav ntawm cov phaj steel thiab cov pob txha, thiab ua kom cov ntshav txaus thiab kev loj hlob thiab rov qab los ntawm periosteum.Lub ntsiab biomechanical sib txawv ntawm tsoos steel phaj thiab tsoos steel phaj yog tias tom kawg tso siab rau kev sib txhuam quab yuam ntawm cov pob txha-phaj cuam tshuam rau cov pob txha.

Lub locking ntsia hlau yog tus kheej tapping ntsia hlau thiab siv tau yam tsis muaj tapping lossis pob txha laum.Nws tsis muaj qhov siab ntawm cov phaj steel thiab cov pob txha cortex, yog li tsis muaj qhov siab ntawm periosteum, thiaj li tiv thaiv cov ntshav ntawm periosteum. Nyob rau hauv cov nqe lus ntawm cov txheej txheem phais, nws muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm minimally invasive lag luam, thiab muaj peev xwm tiv thaiv lub zos cov hlab ntsha ntawm lub pob txha, thiaj li hais tias cov pob txha grafting lag luam tsis xav tau.Lub internal 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 los kho qhov qub occlusal kev sib raug zoo ntawm cov hniav sab sauv thiab sab qis, uas yog, nws kim heev kev sib cuag ntawm cov hniav.Lwm yam nws yuav cuam tshuam qhov rov qab ntawm mastication muaj nuj nqi. Tom qab kho pob txha.Nws muaj peb txoj hauv kev rov 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 tawg 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), qhov tawg muaj ib feem ntawm cov ntaub so ntswg kho, phau ntawv txo qis tsis ua tiav, traction txo txoj kev yuav siv tau.Qhov mandibular fracture multi-purpose lub puab tsaig traction, yog nyob rau hauv cov pob txha mandibular muaj qhov chaw ntawm lub pob txha tawg ntawm qhov chaw ntawm subsection kho hniav arch splint, thiab ces nruab nrab ntawm cov hniav arch splint thiab lub maxillary, nrog ib tug Cov roj hmab me me rau elastic traction, kom nws maj mam rov qab zoo li qub occlusal kev sib raug zoo.Tom qab maxillary pob txha tawg, yog hais tias qhov tawg ntu hloov rov qab, cov hniav arch splint tuaj yeem muab tso rau ntawm maxillary dentition, thiab plaster cap nrog ib tug hlau bracket. ua rau 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.The fibrous cov ntaub so ntswg tsim nyob rau hauv lub dislocation kho ntawm qhov tawg kawg ntawm lub pob txha yog excised los yog lub callus yog chiseled tam sim ntawd, thiab lub puab tsaig yog re-dissected rov qab mus rau nws li qub txoj hauj lwm.Open txo feem ntau yog siv rau tshiab fractures los yog qhib fractures nrog nyuaj. nyob rau hauv phau ntawv txo los yog instability tom qab txo.
