Daim Ntawv Thov Kev Kho Mob Titanium Nails thiab Titanium Rods hauv Kev phais yas

Titanium yog non-toxic thiab non-magnetic. Lub elastic modulus ntawmKev kho mob Titanium Barzoo ib yam li tib neeg cov pob txha, thiab nws muaj kev sib raug zoo nrog tib neeg lub cev, yog li nws tseem hu ua "biological hlau". Titanium kuj yog ib qho tseem ceeb ntawm tsev neeg nco alloy. Nitinol yog thawj zaug pom los ntawm tib neeg kom muaj kev nco. Cov hlau no tuaj yeem "nco" nws lub taub hau. Nws tuaj yeem "rov qab mus rau nws lub xeev qub" thiab rov qab kho nws qhov qub qub. Thiab vim nws muaj titanium, nws kuj muaj zog heev. Yog li ntawd, cov hlau no tau dhau los ua cov khoom siv dav siv ntau tshaj plaws, thiab txog rau hnub no, nws tseem yog ib qho kev ua tau zoo tshaj plaws qhib cov duab nco alloys. Kev siv cov ntawv titanium thiab cov titanium screws los kho cov pob txha pob txha muaj kev npaj txhij txog. Tsuas yog ob peb lub hlis xwb, cov pob txha tshiab thiab cov leeg yuav ua ke nrog cov ntawv titanium. Yog li ntawd, titanium yog cov khoom siv zoo tshaj plaws rau tib neeg kev cog hniav thiab cov pob qij txha.

Zygoma yas phais feem ntau suav nrog ob lub ntsiab lus: ib qho yog qhov yooj yim chiseling ntawm zygoma kom txo tau cov contour ntawm zygoma; lwm qhov yog peb-dimensional osteotomy, uas txo cov zygoma los ntawm kev luv thiab txav cov pob txha. Zygoma chipping feem ntau haum rau cov neeg mob uas muaj lub ntsej muag sab hauv thiab sab nraud. Intraoral incisions feem ntau yog siv los cais thiab nthuav tawm cov zygoma nyob rau hauv lub periosteum. Cov cuab yeej tshwj xeeb yog siv los txhuam thiab nyias ib feem ntawm zygoma tsim los tshem tawm ua ntej kev phais, yog li txo qhov loj ntawm zygoma. Contours lub ntsej muag thiab txhim kho cov duab ntawm lub ntsej muag. Titanium rau tes thiab titanium daim hlau yog siv los kho lub cheekbones kom cov cheekbones yuav tsis plam, ua rau lub ntsej muag contours poob zoo, thiab muaj peev xwm ua tau zoo dua cov nyhuv ntawm cheekbones shaping!

Qhov zoo tshaj plaws ntawm hom kev phais no yog tias nws tawm tsis muaj caws pliav tom qab kev ua haujlwm, tsis muaj seamless thiab yoojyim tsis muaj kab. Qhov nyuaj ntawm peb-dimensional zygomatic osteotomy tau nce ntau, thiab nws yog qhov tsim nyog rau cov neeg mob uas muaj zygomatic arch protrusion. Ntxiv nrog rau qhov intraoral incision, ib qho kev phais feem ntau yog ua nyob rau ntawm qhov zais ntawm cov plaub hau, los yog ib qho kev txiav txim siab yog ua nyob rau hauv cov tawv taub hau ib leeg. Tom qab qhov kev sib cais subperiosteal nthuav tawm tag nrho cov pob txha zygomatic, qhov tshwj xeeb ntawm cov pob txha raug tshem tawm raws li lub computer peb-dimensional simulation tsim. Tom qab ntawd siv cov ntaub ntawv tshwj xeeb xws li cov ntsia hlau titanium kom rov txuas thiab kho cov pob txha tawg, kom tag nrho lub ntsej muag thiab cov duab tuaj yeem hloov mus rau qhov loj tshaj plaws, thiab txawm tias tus neeg mob tuaj yeem ua tiav "reborn" nyhuv. Ntxiv nrog rau zygomatic txo kev phais, rau cov neeg mob me me uas muaj kev nyuaj siab nyob rau hauv nruab nrab ntawm lub ntsej muag tshwm sim los ntawm zygomatic dysplasia los yog tsis xws luag los ntawm congenital los yog kis kab mob, los yog ob tog zygomatic asymmetry, autologous cov ntaub so ntswg transplantation los yog prosthetic phais yuav ua tau. Zygoma augmentation yog ua los ntawm kev sau cov zygoma nrog cov khoom siv lub cev los txhim kho qhov tsos.

Piv nrog rau cov kev kho mob ib txwm muaj xws li cov phaj me me, steel hlau sab hauv fixation, ib lub puab tsaig ligation, thiab intermaxillary traction, sab hauv fixation ntawm titanium phaj nyob rau hauv maxillofacial fractures tsis tawm nti ntawm lub ntsej muag muaj qhov zoo ntawm kev ua haujlwm yooj yim, kev puas tsuaj me me, thiab kev kho mob zoo. . Rau qhov tseeb thiab txhim khu kev qha anatomical fixation, ib qho kev phais extraoral yog yuav tsum tau rau cov txheej txheem condylar thiab zygomatic arch fractures, thiab intraoral incisions feem ntau yog siv rau lwm yam maxillary thiab maxillary fractures. Nws kuj zam kev puas tsuaj rau lub ntsej muag paj hlwb. Lub titanium phaj siv rau kev kho sab hauv yog Zhongbang hom titanium phaj series sib koom ua ke tsim los ntawm Xi'an Zhongbang Tuam Txhab thiab Cov Khoom Siv Kho Hniav ntawm Lub Tsev Kawm Ntawv Qib Siab Fourth Military Medical University. Nws muaj biocompatibility zoo, siab corrosion kuj, thiab yog sib xws nrog tib neeg cov pob txha thiab cov ntaub so ntswg mos. Nws muaj kev sib raug zoo, thiab tshwj tsis yog tias nws kis tau tus kab mob, nws tuaj yeem khaws cia hauv lub cev kom ntev li ib txwm muaj, tsis tas yuav tsum muaj kev phais thib ob kom tshem tawm nws, uas txo cov nqi tsev kho mob thiab kev lag luam ntawm cov neeg mob. Qhov teeb meem ntawm intermaxillary traction nyob rau hauv titanium phaj sab hauv fixation, nws ntseeg tau hais tias intraoperative intermaxillary traction tuaj yeem muab kev kho kom zoo ntawm cov pob txha tawg thiab muaj kev sib raug zoo occlusal, thiab tseem tuaj yeem tiv thaiv kev drilling, thiab ntu tawg yuav raug tshem tawm dua thaum lub titanium ntsia hlau yog ntxig. Kev cuam tshuam ntawm kev sib raug zoo occlusal yog tshwm sim. Tsuas yog cov neeg mob maxillary thiab maxillary pob txha pob txha uas yuav tsum tau pab nrog intermaxillary traction thiab fixation li ntawm 1 lub lis piam tom qab fixation, lwm yam fractures feem ntau tsis xav tau traction thiab fixation tom qab fixation, vim hais tias lub sij hawm traction yog luv thiab tus neeg mob lub cev nqaij daim tawv. kev ua haujlwm ntawm kev sib koom ua ke ntawm mandibular tsis tshua muaj kev cuam tshuam, nws yog ib qho yooj yim los tswj lub qhov ncauj huv si, thiab nws muaj peev xwm noj tau, uas yog muaj txiaj ntsig zoo rau tus neeg mob noj zaub mov zoo thiab kho qhov txhab, thiab tib lub sijhawm zoo heev txo qhov mob ntawm tus neeg mob piv rau yav dhau los. Kev xaiv ntawm txoj hauj lwm ntawm titanium phaj fixation, nws tau txiav txim siab tias qhov kev xaiv ntawm txoj hauj lwm tsim nyog ntawm titanium splint yog ib qho ntawm cov xwm txheej los xyuas kom meej qhov kev vam meej ntawm titanium phaj sab hauv fixation. Mandibular fractures uas tsis yog condylar fractures tau kho raws li Champi zoo tshaj kab, uas yog, mandibular lub cev pob txha tawg titanium phaj tau tsau rau ntawm sab hauv cov pob txha pob txha ntawm sab nraud oblique kab, uas yog, nruab nrab ntawm cov hniav hauv paus thiab cov kwj dej alveolar inferior. , nyob rau hauv nruab nrab thiab ib sab ntawm midline Lub pob txha yuav tsum tau kho nrog ob qho tib si titanium. daim hlau. Qhov chaw zoo tshaj plaws los tso cov phiaj xwm micro-titanium hauv midface fractures yuav tsum yog lub orbital rim, zygomatic alveolar ridge, ntug ntawm pyriform qhov, thiab cov ntsia hlau yuav tsum muab tso rau ntawm cov pob txha tuab ntawm cov ncej ntsug. Kev kho mob titanium Bar, biomedical titanium (cov khoom siv tseem ceeb: kho mob titanium phaj, kho mob titanium hlau) yog ib ceg tseem ceeb ntawm cov khoom siv kho mob, feem ntau yog siv los kho lossis hloov tib neeg cov ntaub so ntswg, kabmob lossis txhim kho lawv txoj haujlwm, nrog cov ntsiab lus siab thiab kev lag luam muaj txiaj ntsig. cov khoom siv thauj khoom tshiab. Thaum cov nqaij pob txha tshiab tau qhwv ib ncig ntawm "cov pob txha titanium", cov pob txha titanium no pib tswj cov kev ua ub no ntawm tib neeg lub cev. Titanium yog dav faib nyob rau hauv tib neeg lub cev, thiab cov ntsiab lus nyob rau hauv tib neeg lub cev yog tsis ntau tshaj 15 mg ib 70 kg lub cev hnyav, thiab nws lub luag hauj lwm yog tsis meej. Txawm li cas los xij, nws tau raug lees paub tias titanium tuaj yeem txhawb nqa phagocytes thiab txhim kho kev tiv thaiv. Titanium nws tus kheej yog cov hlau ruaj khov uas muaj siab hardness thiab lub teeb yuag uas yuav tsis xeb los yog deteriorate los yog ua rau cov hlau tsis haum. Titanium muaj cov yam ntxwv tshwj xeeb tam sim no, uas yuav muaj txiaj ntsig zoo rau lub cev ntawm tib neeg lub cev thiab nws cov tshuaj lom neeg ruaj khov yuav tsis hloov pauv lossis tsis zoo rau lub sijhawm. Hauv 10 xyoo dhau los, kev lag luam kev loj hlob ntawm cov ntaub ntawv biomedical thiab cov khoom lag luam tau khaws cia li ntawm 30%. Nws kwv yees tias nyob rau hauv 10-20 xyoo tom ntej, kev lag luam khoom siv kho mob, suav nrog cov ntaub ntawv kho mob hlau, yuav ncav cuag qhov ntsuas ntawm cov khoom lag luam tshuaj thiab yuav dhau los ua lub lag luam loj tshaj plaws hauv ntiaj teb hauv xyoo pua 21st. pillar kev lag luam ntawm kev lag luam.
