Mini fragment yog dab tsi?
Mini fragment hais txog ib hom orthopedic implant siv los kho cov pob txha me me thiab cov pob txha tawg, feem ntau yog cov ntsuas 2.0 txog 3.5 hli inch. Cov implants no feem ntau siv rau hauv tes thiab ko taw phais, nrog rau lwm yam kev phais uas muaj cov pob txha me me. Mini fragment implants yog tsim los muab kev txhim kho ruaj khov thiab txhawb kev kho kom zoo, thiab muaj ntau yam duab thiab ntau thiab tsawg kom haum raws li qhov kev xav tau ntawm kev phais. Lawv feem ntau yog ua los ntawm cov khoom siv biocompatible xws li titanium lossis stainless hlau, thiab feem ntau yog siv cov cuab yeej tshwj xeeb.
Dab tsi yog hom mini fragment?
Mini fragment daim hlau muaj nyob rau hauv ntau hom thiab ntau thiab tsawg kom haum rau qhov sib txawv anatomical qhov chaw thiab pob txha loj. Qee hom ntawm mini fragment phaj muaj xws li:
Ib feem peb ntawm cov tubular daim hlau: Cov no yog siv rau cov pob txha me me los yog cov pob txha me me uas muaj qhov txwv rau kev kho, xws li hauv tes, dab teg, thiab pob taws.
T-plates: Cov phaj no feem ntau yog siv rau hauv kev puas tsuaj ntawm lub vojvoog distal, pob taws, thiab calcaneus.
L-plates: Cov phaj no yog siv rau hauv cov pob txha pob txha uas yuav tsum tau kho kom haum rau qhov ntev ntawm cov pob txha, xws li hauv cov pob txha femoral.
H-plates: Cov phaj no yog siv rau hauv cov pob txha ntawm cov tibia proximal, nrog rau kev kho mob ntawm cov neeg tsis sib koom ua ke.
Y-plates: Cov phaj no yog siv rau cov pob txha ntawm lub zes humerus, clavicle, thiab distal femur.
Hook daim hlau: Cov phaj no yog siv rau hauv cov pob txha tsis yooj yim uas cov txheej txheem plating tsis ua tau lossis ua tsis tiav, xws li hauv pob txha ntawm sab tibial toj siab.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias hom thiab qhov ntau thiab tsawg ntawm cov phaj me me uas siv yuav yog nyob ntawm tus qauv pob txha tshwj xeeb thiab tus kws phais qhov kev nyiam.
Cov ntaub ntawv ntawm lub xauv phaj?
Locking daim hlau feem ntau yog ua los ntawm cov khoom siv biocompatible xws li titanium, titanium alloy, lossis stainless hlau. Cov ntaub ntawv no muaj lub zog zoo, nruj, thiab corrosion kuj, ua rau lawv zoo tagnrho rau siv hauv orthopedic implants. Tsis tas li ntawd, lawv yog inert thiab tsis hnov mob nrog lub cev nqaij daim tawv, txo qhov kev pheej hmoo ntawm kev tsis lees paub lossis kev mob. Qee qhov xauv daim hlau kuj tseem yuav coated nrog cov ntaub ntawv xws li hydroxyapatite lossis lwm yam txheej txheej los txhim kho lawv kev koom ua ke nrog cov pob txha.
Lub phaj twg zoo dua titanium lossis stainless hlau?
Ob lub titanium thiab stainless hlau daim hlau feem ntau yog siv rau hauv kev phais orthopedic, nrog rau kev xauv daim hlau. Kev xaiv ntawm ob cov ntaub ntawv yog nyob ntawm ntau yam, nrog rau hom kev phais, tus neeg mob cov keeb kwm kev kho mob thiab kev nyiam, thiab tus kws phais qhov kev paub thiab nyiam.
Titanium yog ib qho khoom siv hnyav thiab muaj zog uas yog biocompatible thiab tiv taus corrosion, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev cog qoob loo. Titanium daim hlau tsis tshua muaj zog dua cov hlau tsis muaj steel hlau, uas tuaj yeem pab txo kev ntxhov siab ntawm cov pob txha thiab txhawb kev kho. Tsis tas li ntawd, titanium daim hlau yog cov xov tooj cua ntau dua, uas txhais tau hais tias lawv tsis cuam tshuam nrog kev kuaj duab xws li X-ray lossis MRI.
Stainless hlau, ntawm qhov tod tes, yog cov khoom muaj zog thiab tawv tawv uas kuj biocompatible thiab tiv taus corrosion. Nws tau siv nyob rau hauv orthopedic implants rau xyoo lawm thiab yog ib tug sim-thiab-tseeb khoom. Cov hlau tsis muaj hlau tsis tshua kim dua li cov titanium daim hlau, uas tuaj yeem ua rau muaj kev xav rau qee tus neeg mob.
Vim li cas titanium daim hlau siv hauv kev phais?
Titanium daim hlau feem ntau siv hauv kev phais vim tias lawv cov khoom tshwj xeeb uas ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev cog qoob loo. Qee qhov txiaj ntsig ntawm kev siv titanium daim hlau hauv kev phais muaj xws li:
Biocompatibility: Titanium yog biocompatible heev, uas txhais tau hais tias nws tsis zoo li yuav ua rau muaj kev tsis haum tshuaj lossis raug tsis lees paub los ntawm lub cev tiv thaiv kab mob. Qhov no ua rau nws muaj kev nyab xeeb thiab txhim khu kev qha khoom siv rau hauv kev kho mob cog.
Lub zog thiab ruaj khov: Titanium yog ib qho ntawm cov hlau uas muaj zog tshaj plaws thiab ruaj khov, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev cog qoob loo uas yuav tsum tau tiv thaiv kev ntxhov siab thiab kev siv txhua hnub.
Corrosion tsis kam: Titanium muaj zog tiv taus corrosion thiab tsis tshua muaj kev cuam tshuam nrog cov kua dej hauv lub cev lossis lwm yam khoom hauv lub cev. Qhov no yuav pab tiv thaiv qhov cog los ntawm corroding los yog degrading lub sij hawm.
Radiopacity: Titanium yog radiopaque heev, uas txhais tau hais tias nws tuaj yeem pom tau yooj yim ntawm X-rays thiab lwm yam kev kuaj pom. Qhov no ua rau nws yooj yim dua rau cov kws kho mob saib xyuas qhov cog thiab xyuas kom meej tias nws ua haujlwm zoo.
