Pankhani ya maxillofacial trauma and reconstruction, zovuta zamafupa a anatomy ndi kutsitsa zimayika zofunikira kwambiri pazida zopangira mkati. Mwa izi, mbale yaying'ono yamafupa - monga Locking Maxillofacial Mini Straight Plate - yakhala yankho lofunikira pakukhazikitsa fractures m'madera osalimba a nkhope.
Nkhaniyi ikuwunika zaukadaulo waposachedwa mumini fupa mbale, kuyang'ana pa kusankha zinthu, kupanga malo otsetsereka, ndi kukonza zotsekera zomwe zimapangitsa kuti maopaleshoni azichita komanso kukhazikika kwanthawi yayitali.
Kusintha Kwazinthu: Kupambana kwa Titanium ndi Titanium Alloys
Kusankha zinthu ndizofunikira kwambiri popanga machitidwe okonza mafupa. Mafupa ang'onoang'ono amayenera kukhala ogwirizana bwino ndi biocompatibility, mphamvu zamakina, kukana kutopa, komanso kuyanjana kwa radiographic. Titaniyamu ndi ma aloyi ake atuluka ngati muyezo wagolide pantchito iyi.
The Locking Maxillofacial Mini Straight Plate yochokera ku Shuangyang imapangidwa kuchokera ku titaniyamu yoyera yachipatala, yochokera ku German ZAPP titaniyamu. Izi zimatsimikizira kuti biocompatibility yabwino kwambiri, kufanana kwambewu zabwino, ndi kusokoneza pang'ono kwa kulingalira-ubwino wofunikira pamayeso a postoperative CT ndi MRI.
Kuchokera pamalingaliro aumisiri, titaniyamu imapereka maubwino angapo:
Superior Biocompatibility:
Titaniyamu mwachilengedwe imapanga wosanjikiza wokhazikika wa TiO₂ oxide pamwamba pake, womwe umalimbikitsa kuphatikizika kwa osteointegration ndikuletsa dzimbiri m'chilengedwe.
Kulimba Kwambiri ndi Kukana Kutopa:
Titaniyamu alloys monga Ti-6Al-4V kapena Ti-6Al-7Nb amasonyeza kwambiri kulimba mphamvu ndi kusinthasintha, kulola fupa mbale kukana cyclic makina kupsyinjika pa mastication ndi machiritso.
Kugwirizana kwa Zithunzi:
Mosiyana ndi zitsulo zosapanga dzimbiri kapena cobalt-chromium, titaniyamu imapanga zinthu zochepa kwambiri pazithunzi za CT kapena MRI, zomwe zimapangitsa kuti munthu aziwunika bwino pambuyo pa opaleshoni.
Kuphatikiza apo, mbale ya mini bone imakhala ndi chithandizo cha anodized pamwamba, chomwe chimapangitsa kulimba, kukana kuvala, komanso moyo wautali wa implant. Kuchokera pamalingaliro aumisiri, anodization imawongoleranso mawonekedwe a oxide layer, ndikuwongolera kutopa kwake komanso kukana dzimbiri.
Ngakhale titaniyamu idakhazikitsidwa kale, kukhathamiritsa kopitilira muyeso kukuchitikabe, makamaka pakukonzanso kwa microstructure, kuwongolera kupsinjika kotsalira, komanso kusinthidwa kwapansi - kuti apititse patsogolo kulimba kwa implant ndikuchepetsa kutulutsidwa kwa chitsulo pakapita nthawi.
Kutalikirana kwa Mabowo ndi Mapangidwe a Geometric: Kuyanjanitsa Kukhazikika ndi Anatomy
Maonekedwe a mbale yaying'ono ya mafupa - kuphatikiza makulidwe ake, malo otalikirapo mabowo, ndi kutalika kwake - imathandizira kwambiri pamakina ake komanso kusinthasintha kwa maopaleshoni.
Mndandanda wa Locking Maxillofacial Mini Straight Plate uli ndi masanjidwe angapo, kuphatikiza 6-hole (35 mm), 8-hole (47 mm), 12-hole (71 mm), ndi 16-hole (95 mm), onse okhala ndi makulidwe a 1.4 mm. Zosiyanasiyanazi zimalola madokotala ochita opaleshoni kusankha njira yoyenera kwambiri malinga ndi mtundu wa fracture, mawonekedwe a fupa, ndi zofunikira zokonzekera.
Kuchokera pamalingaliro aukadaulo, masitayilo a dzenje (mtunda pakati pa zomangira) amakhudza mwachindunji magawo angapo ofunikira:
Kugawa Kupsinjika:
Kutalikirana kwambiri kungayambitse kupindika kapena kutopa ponyamula katundu, pomwe malo ocheperako amatha kufooketsa gawo la fupa ndikuwonjezera chiwopsezo chokoka. Kutalikirana bwino kumatsimikizira kusamutsa katundu wofanana pakati pa fupa ndi dongosolo lokhazikika.
Bone-Screw Interface:
Kutalikirana koyenera kumawonetsetsa kuti screw iliyonse imathandizira kunyamula katundu popanda kupanga nsonga zapamtunda zomwe zitha kufulumizitsa kutopa.
Kusintha kwa Opaleshoni:
Mbaleyo iyenera kugwirizana ndendende ndi fupa pamwamba, makamaka mu mizere yokhotakhota ya dera maxillofacial. Mabowo a geometry ndi masitayilo amapangidwa mosamala kuti alole kusinthika kwa screw anglation ndikupewa kusokonezedwa ndi mawonekedwe oyandikana nawo a anatomical.
Kafukufuku wa Finite Element Analysis (FEA) pa mbale zofananira za mafupa ang'onoang'ono awonetsa kuti kusakhazikika bwino kwa mabowo kumatha kuwonjezera kupsinjika kwa von Mises kupitilira mphamvu yokolola ya titaniyamu, kumachepetsa kutopa. Chifukwa chake, masitayilo olondola ndi ma geometry osasinthasintha ndizofunikira zaumisiri pakupanga mbale.
Kupititsa patsogolo Njira Zotsekera: Kuchokera Kukhazikika Kukhazikika mpaka Kukhazikika Kwachangu
Mambale osatseka achikhalidwe amadalira kukangana pakati pa mbale ndi fupa kuti likhale lokhazikika. Komabe, m'malo osinthika komanso ovuta kwambiri a nkhope, kukhazikika kwamtunduwu kumatha kukhala kosavuta kumasula kapena kutsetsereka.
Ma mbale amakono okhoma mini-monga omwe ali mu Maxillofacial Locking System-amaphatikiza makina otsekera pakati pa screw mutu ndi mbale, kupanga mawonekedwe amodzi, ogwirizana. Chidziwitso ichi chikuwonetsa kudumpha kwakukulu pakukhazikika komanso kulondola.
Makina otsekera omwe amagwiritsidwa ntchito mu Locking Maxillofacial Mini Straight Plate amakhala:
Ukadaulo wotsekera wa compression umatsimikizira kuyanjana kolimba pakati pa ogwira ntchito ndi mbale.
Mapangidwe a mabowo ogwiritsidwa ntchito kawiri, ogwirizana ndi zomangira zokhoma komanso zosatseka, zomwe zimapereka kusinthasintha kwakukulu panthawi ya opaleshoni.
Ubwino waukadaulo wamakina otsekera ndi awa:
Kulimbitsa Kukhazikika ndi Kukhazikika:
Mawonekedwe otsekedwa a screw-plate amakhala ngati mamangidwe amkati okhazikika, kuwongolera kugawa katundu ndi kuchepetsa micromotion pamalo ophwanyika.
Kuchepetsa Kupsinjika Kwa Mafupa:
Popeza mbaleyo sichidaliranso kugwedezeka kwa mafupa, imapewa kuponderezedwa kwambiri pa periosteum, kusunga magazi komanso kulimbikitsa kuchira msanga kwa mafupa.
Kulimbana ndi Kutopa Kwambiri:
Poletsa kutsetsereka pang'ono pakati pa screw mutu ndi bowo la mbale, mawonekedwe otsekera amachepetsa kumeta ubweya wamba ndikuwonjezera moyo wantchito.
Kuwongolera uku kumafuna kulolerana kolondola kwambiri kwa makina, makamaka pakumangirira ndi kusokoneza mawonekedwe a screw-plate. Kukhazikika kopanga kumawonetsa kukhwima kwa uinjiniya wamakina amakono okonzera.
Tsogolo la Tsogolo: Kutsata Njira Zanzeru komanso Zosintha Mwamakonda Anu
M'badwo wotsatira wa zida za maxillofacial fixation ukupita patsogolo kwambiri, umakonda kwambiri, komanso kuyankha kwachilengedwe kwachilengedwe. Zatsopano zomwe zikubwera zikuphatikiza:
Mitundu Yatsopano ya Titanium:
Kukula kwa ma alloys a β-phase ndi Ti-Mo-Fe omwe amapereka mphamvu yayikulu yokhala ndi modulus yocheperako, kuchepetsa kutchinga kupsinjika ndikuwongolera kusintha kwa mafupa kwanthawi yayitali.
Mimbale Zosindikizidwa za 3D:
Kupanga kowonjezera kumalola maopaleshoni kupanga mbale za odwala zomwe zimagwirizana ndendende ndi mafupa, kuchepetsa kupindika kwa intraoperative ndi kukhathamiritsa kutumiza katundu.
Kugwiritsa Ntchito Pamwamba:
Njira monga nano-texturing, zokutira zothira tizilombo toyambitsa matenda, kapena mankhwala ochiritsira a bioactive pamwamba akufufuzidwa kuti afulumizitse osseointegration ndi kuchepetsa chiopsezo cha matenda.
Kukhathamiritsa Kwamapangidwe Anzeru:
Finite Element Modeling (FEM) ikugwiritsidwa ntchito pakuwongolera bwino dzenje la geometry, makulidwe a mbale, ndi kupindika, kuwonetsetsa kugawa kwapang'onopang'ono kofanana komanso moyo wotopa bwino.
Mapeto
Kuchokera pa kusankha zinthu ndi kukhathamiritsa kwa malo otsetsereka mpaka kukayika makina otsekera, mbale zamakono za mini bone za opaleshoni ya maxillofacial zimaphatikizana mozama pazachipatala komanso luso lamakina.
The Locking Maxillofacial Mini Straight Plate
Zimapereka chitsanzo cha kupita patsogolo kumeneku ndi kapangidwe kake ka titaniyamu kachipatala, pamwamba pa anodized, geometry yolondola, komanso kapangidwe kake kotsekeka kosiyanasiyana - kupatsa madokotala ochita opaleshoni njira yodalirika, yosinthika, komanso yowongoleredwa ndi biomechanically.
Pamene sayansi yakuthupi ndi kupanga mwatsatanetsatane zikupitilirabe kusinthika, m'badwo wotsatira wa mafupa ang'onoang'ono udzabweretsa mphamvu zokulirapo, kufanana kwa thupi, ndi magwiridwe antchito achilengedwe, kuthandiza maopaleshoni kuti athe kuchira mwachangu komanso zotsatira zabwino pakumanganso maxillofacial.
