locking maxillofacial reconstruction ncaj phaj (xov qhia)

Mandible tawg

1. Cov yam tseem ceeb uas cuam tshuam rau kev hloov pauv ntawm cov pob txha tawg tom qab mandibular fracture muaj xws li: qhov chaw tawg, qhov loj thiab kev coj ntawm sab nraud quab yuam, kev taw qhia thiab inclination ntawm cov kab tawg, seb puas muaj cov hniav hauv qhov tawg ntu thiab rub cov nyhuv ntawm cov leeg sib txuas. Kev tawg ntu feem ntau tshwm sim vim qhov sib txawv ntawm cov pob txha thiab cov leeg rub hauv cov lus qhia sib txawv.

Lub titanium mandibular phaj tau siv rau kev kho sab hauv, thiab tau txais txiaj ntsig zoo.Qhov zoo ntawm cov splint yog raws li nram no: lub nyias thiab nqaim titanium phaj tuaj yeem ua rau lub zog ntawm kev kho hniav.The prefabricated titanium phaj tuaj yeem ua kom haum rau lub kaum sab xis ntawm lub mandible, thiab lub phaj kuj tuaj yeem khoov kom haum rau radian. ntawm lub mandible.Lub titanium phaj yog tsau nrog cov tawg kawg ntawm ob sab ntawm cov pob txha kom ncaj qha dais thiab coj cov hniav quab yuam, yog li ntawd cov pob txha graft flap tsis dais lub dag lub zog ntawm cov hniav thiab yog heev pab tau rau cov pob txha kho.Retention. , tsis xav tau kev kho sab nraud, lub qhov txhab kho tuaj yeem noj tau zoo, tsis tas yuav tos rau kev tsim cov pob txha callus, yog qhov tsim nyog rau kev rov ua haujlwm thaum ntxov, txo qhov ntev ntawm kev nyob hauv tsev kho mob ntawm cov neeg mob.Nyob rau hauv cov neeg mob loj mandibular defects vim mus rau qog resection thiab lwm yam yog vim li cas, ua ke ntawm vascular graft ntawm iliac pob txha flap thiab kho hom titanium splint sab hauv fixation yog heev pab tau rau lub reconstruction ntawm tus neeg mob lub mandibular pob txha thiab rov qab los ntawm cov tsos, zom, nqos, ua pa thiab hais lus thiab lwm yam. cov haujlwm tseem ceeb.

Feem ntau, mandibular locking phaj yuav tsum tau tsim symmetrically kom tau raws li cov kev xav tau sib txawv ntawm sab laug thiab sab xis ntawm maxillofacial.Meanwhile, lub xauv thiab shaping screws ntawm lub mandibular locking phaj yog tsau ntawm cov ces kaum ntawm cov pob txha phaj, uas yog tsis conducive rau phais fixation ntawm tawg los yog txo.Maxillofacial universal lock phaj, nrog rau maxillofacial universal xauv phaj, mounting qhov, nrog mounting qhov. Raws li tau piav nyob rau hauv maxillofacial universal central locking phaj dabtsi yog khoov, maxillofacial universal piav txog lub kaum sab xis ntawm 120 degrees ntawm lub xauv phaj ntawm ob sab, raws li tau piav nyob rau hauv maxillofacial universal xauv phaj sab nrog ntau lub qhov mounting, raws li tau piav nyob rau hauv maxillofacial universal phaj. sab nrog ntau lub qhov mounting, piav nyob rau hauv lub installation qhov, koom tes nrog lub mounting qhov symmetric tis, piav nyob rau hauv lub installation qhov axis thiab koom tes nrog installation qhov axis.Lub puab sab ntawm lub installation qhov yog muab nrog ib tug trapezoidal installation qhov, lub trapezoidal installation qhov seem yog trapezoidal, sab hauv ntawm lub qhov sib txuam installation qhov yog muab nrog ib tug txuam trapezoidal installation qhov seem yog trapezoidal, lub trapezoidal installation qhov thiab qhov sib txuam trapezoidal installation qhov yog symmetrically faib.Maxillofacial universal locking phaj yuav siv tau ntawm ob sab. , tsis tas yuav tsim cov khoom lag luam sab laug thiab sab xis, qhov kev teeb tsa lub qhov, nrog lub qhov teeb tsa tuaj yeem ua tiav 30 degrees Angle ntsia thawv tso.Maxillofacial universal locking phaj, tuaj yeem ua tiav 30 degrees dav lub kaum ntse ntse xauv, ib-kauj ruam locking, tsis hais ob tog , tsis hais sab laug thiab sab xis, ntau yam kev xav tau tuaj yeem ua tiav los ntawm lub phaj.
