Xauv maxillofacial daim hlauyog cov khoom siv txhim kho pob txha uas siv lub tshuab xauv los tuav cov ntsia hlau thiab daim hlau ua ke.Qhov no muab ntau stability thiab rigidity rau cov pob txha tawg, tshwj xeeb tshaj yog nyob rau hauv complex thiab comminuted fractures.
Nyob ntawm qhov tsim ntawm lub kaw lus kaw, xauv cov maxillofacial daim hlau tuaj yeem muab faib ua ob hom: threaded locking daim hlau thiab tapered locking daim hlau.
Muaj cov xov sib txuas ntawm cov ntsia hlau taub hau thiab phaj qhov ntawm cov xov xauv phaj.Sib piv qhov loj thiab cov duab ntawm lub taub hau ntsia hlau nrog lub phaj qhov, thiab nruj nreem ntsia hlau kom txog thaum nws raug kaw nrog lub phaj.Qhov no ua rau lub kaum sab xis ruaj khov uas tiv thaiv cov screws los ntawm loosening los yog ua angled.
Cov ntsia hlau taub hau thiab phaj qhov ntawm tapered locking daim hlau muaj ib tug conical zoo.Cov ntsia hlau taub hau thiab lub qhov rooj yog qhov sib txawv me ntsis thiab cov duab, ntxig cov ntsia hlau kom txog thaum wedged tiv thaiv lub rooj tsavxwm.Qhov no tsim kev sib txhuam uas tuav cov ntsia hlau thiab phaj ua ke.
Ob hom ntawmxauv maxillofacial daim hlaumuaj lawv tus kheej zoo thiab qhov tsis zoo.Threaded locking daim hlau tso cai rau kev ua kom zoo dua ntawm cov ntsia hlau thiab phaj, tab sis yuav tsum tau siv sij hawm ntau thiab kev txawj los ntxig cov ntsia hlau raws nraim rau hauv nruab nrab ntawm lub phaj qhov.Tapered locking daim hlau tso cai rau kom yooj yim dua thiab yooj yim ntawm cov ntsia hlau ntxig, tab sis nws yuav ua rau muaj kev ntxhov siab ntau dua thiab deformation ntawm lub phaj.
Xauv maxillofacial daim hlau kuj tuaj nyob rau hauv cov duab sib txawv thiab ntau thiab tsawg nyob ntawm qhov chaw thiab qhov hnyav ntawm pob txha.Qee cov qauv ntawm cov xauv lub puab tsaig yog:
Ncaj phaj: siv rau cov pob txha yooj yim, cov kab sib dhos xws li symphysis thiab parasymphysis fractures.
Bending phaj: siv rau nkhaus thiab angular fractures, xws li angular fractures thiab lub cev puas.
L-shaped phaj: siv rau angular thiab oblique fractures, xws li ramus thiab condylar fractures.
T-shaped steel phaj: siv rau T-shaped thiab bifurcated fractures, xws li pob txha alveolar thiab zygomatic pob txha pob txha.
Y-shaped steel phaj: siv rau Y-zoo li thiab trifurcated puas, xws li orbital thiab qhov ntswg orbital puas.
Mesh phaj: siv rau qhov tsis sib xws thiab comminuted fractures, xws li lub hauv pliaj thiab lub cev pob txha.
Xauv maxillofacial phajyog ib qho cuab yeej siv siab heev thiab siv tau zoo rau kev kho cov pob txha maxillofacial.Nws muab kev ruaj ntseg zoo dua, kho kom zoo nkauj thiab zoo nkauj dua li cov hlau tsis-locking.Txawm li cas los xij, nws kuj yuav tsum tau muaj kev txawj ntse ntau dua, cov khoom siv thiab cov nqi ntau dua li cov phaj tsis-locking.Yog li ntawd, qhov kev xaiv ntawm xauv maxillofacial daim hlau yuav tsum yog raws li tus neeg xav tau kev pab thiab nyiam ntawm tus neeg mob thiab tus kws phais.
