Yuav Ua Li Cas Xaiv Ntawm Stainless Hlau Veterinary Pob Txha Phaj Thiab Titanium Alloy Veterinary Pob Txha Daim Hlau?

Hauv kev phais kws kho tsiaj orthopedic, kev xaiv ntawm cov khoom siv kho qhov muag ncaj qha cuam tshuam rau qhov zoo ntawm kev kho pob txha thiab qhov ua tiav ntawm kev phais. Stainless hlau thiab titanium alloy yog tam sim no ob lub ntsiab khoom siv rau cov pob txha veterinary daim hlau, txhua tus muaj qhov tshwj xeeb ntawm lub cev thiab cov khoom siv roj ntsha. Yuav ua li cas xaiv kev tshawb fawb hauv cov xwm txheej tshwj xeeb tau dhau los ua ib qho kev kawm uas niaj hnub kws kho tsiaj orthopedic kws phais yuav tsum paub.
 

 

Stainless hlau vet pob txha phaj, raws li ib txwm thiab classic cov ntaub ntawv, muaj superior mechanical zog raws li lawv cov ntsiab kom zoo dua. Feem ntau siv 316L kev kho mob- qib stainless hlau muaj ntau dua modulus ntawm elasticity thiab yield zog, muab kev txhawb zog fixation. Cov yam ntxwv no tshwj xeeb tshaj yog haum rau qhov hnyav -cov kabmob pob txha pob txha (xws li femur thiab tibia) hauv cov dev loj, lossis kho cov pob txha tawg uas xav tau kev tiv thaiv siab. Txawm li cas los xij, nws qhov rigidity siab tuaj yeem ua rau "kev nyuaj siab tiv thaiv" cov nyhuv, thiab muaj qhov ua tau tsawg heev ntawm nickel ion rhiab heev.

 

Qhov zoo ntawmtitanium alloy pob txha daim hlaudag nyob rau hauv lawv biocompatibility thiab mechanical adaptability. Lawv elastic modulus nyob ze rau ntawm cov pob txha cortical, ua kom zoo tshaj "physiological load-cov kabmob" thiab txo cov pob txha pob txha los ntawm kev tiv thaiv kev ntxhov siab. Ib txheej oxide ruaj khov tuaj yeem tsim rau saum npoo ntawm titanium alloys, nthuav tawm bioinertness zoo heev thiab osteointegration peev xwm, thiab tsis tshua muaj kev cuam tshuam cov ntaub so ntswg. Tsis tas li ntawd, nws tsim cov khoom cuav tsawg dua hauv CT thiab MRI scans dua li cov hlau tsis muaj steel, ua kom muaj kev ntsuam xyuas raug tom qab.

 

 

Kev xaiv ntawm cov khoom siv yuav tsum yog raws li kev ntsuam xyuas ntawm tus tsiaj qhov loj, hom pob txha, qhov chaw anatomical, thiab cov qauv kho kom zoo:

Cov dev loj thiab siab -Load Sites: Rau cov dev loj uas hnyav tshaj 25kg, cov dev ua haujlwm, thiab pob txha ntawm qhov hnyav loj -cov pob txha xws li lub femur thiab tibia, los yog cov pob txha loj heev uas xav tau kev ruaj ntseg siab heev, cov hlau tsis muaj zog muaj zog, muab kev txhim khu kev qha thiab muaj zog pib.

Cov tsiaj me, qhov chaw tsis yooj yim, thiab cov rooj plaub uas yuav tsum muaj Biocompatibility siab:

Rau cov miv, cov dev me, thiab cov tsiaj txawv txawv, uas cov pob txha yog cov mos mos, titanium alloy daim hlau muab cov ductility zoo thiab malleability, ua kom yooj yim intraoperative dabtsi yog khoov thiab shaping kom zoo dua mus rau skeletal anatomy.

Rau periarticular fractures, maxillofacial fractures, los yog qhov chaw uas tsis muaj cov ntaub so ntswg npog (xws li lub vojvoog thiab ulna), titanium alloys pom cov ntaub so ntswg qis dua thiab zoo biocompatibility, txo qhov khaus rau cov nqaij mos nyob ib puag ncig thiab muaj kev pheej hmoo ntawm cov teeb meem.

Rau cov neeg mob uas xav tias yuav tsum muaj kev phais thib ob kom tshem tawm cov implants, titanium alloys tsim ib qho kev sib cuam tshuam nrog cov ntaub so ntswg, ua kom tshem tawm tau yooj yim dua.

Cov kev xav tau tshwj xeeb xav tau: Yog tias nquag CT lossis MRI ua raws- yuav tsum tau ua tom qab kev phais (xws li kev raug mob hnyav nrog rau tus txha nqaj qaum lossis lub hlwb), titanium alloy tsim cov khoom cuav tsawg dua thiab yog qhov kev xaiv zoo dua.

 

 

Stainless hlau pob txha daim hlau feem ntau muab cov nqi tseem ceeb, ua rau lawv muaj kev xaiv zoo rau cov neeg mob uas muaj peev nyiaj tsawg lossis qhov uas tswj tag nrho cov nqi kho mob tseem ceeb heev. Thaum titanium alloy pob txha daim hlau yog kim dua rau ib chav tsev, lawv qhov ntev - cov txiaj ntsig zoo hauv kev txhawb nqa kev kho mob, txo cov teeb meem, thiab ua kom yooj yim rau kev ntsuam xyuas cov duab yuav ua rau muaj txiaj ntsig zoo dua thiab kev lag luam rau cov xwm txheej tshwj xeeb.

 

 

Hauv kev xaus, tsis muaj qhov "superiority" lossis "inferiority" ntawm stainless hlau thiab titanium alloy pob txha daim hlau; qhov tseem ceeb nyob rau hauv "haum" rau cov ntaub ntawv tshwj xeeb.

Hauv kev xyaum kho mob, rau feem ntau ntawm cov pob txha pob txha nyob rau hauv me me mus rau nruab nrab- cov tsiaj loj, thiab rau cov neeg mob uas xav tau biocompatibility siab thiab kev ntsuam xyuas, cov txiaj ntsig zoo ntawm titanium alloy pob txha daim hlau tau nce ntxiv, uas sawv cev rau ib qho kev sib txawv hauv cov ntaub ntawv kho tsiaj orthopedic. Txawm li cas los xij, rau siab - thauj cov pob txha hauv cov dev loj nrog cov peev nyiaj tsawg, cov pob txha stainless hlau tseem muaj kev ntseeg siab thiab sijhawm- sim xaiv.
