Cov pob txha sib txawv, txawv screws

Nyob rau hauv ib txoj kev tshawb no muab piv lub dag lub zog ntawm plaub muag muaj pob txha screws nrog sib txawv suab, ntsia hlau tuav tau muaj feem xyuam rau tus pob txha ceev, xov tsim, thiab tus naj npawb ntawm threads uas meshed tus pob txha. Txij li cov pob txha sib txawv muaj qhov sib txawv, nws ua rau kev nkag siab tias hom pob txha muaj feem cuam tshuam rau cov ntsia hlau tsim.

Cortical (los yog compact) pob txha tsim cov tawv, ntom txheej txheej ntawm cov pob txha uas muab kev txhawb nqa rau lub cev thiab pab tiv thaiv cov kab mob hauv nruab nrog cev. Cov pob txha du, dawb, khov kho muaj li 80 feem pua ​​​​ntawm cov neeg laus' lub cev hnyav.

Cov pob txha pob txha (tseem hu ua pob txha spongy) tsim cov ntaub so ntswg sab hauv uas tsim cov pob txha ntawm tib neeg, feem ntau ntawm cov lus qhia ntawm lwm cov pob txha, nyob ze cov pob qij txha, thiab hauv vertebrae. Cov pob txha Cancellous tsis tshua ntom, softer, thiab hloov tau ntau dua li cov pob txha cortical.

Yog li ntawd, CNC Swiss machining tuaj yeem siv los tsim cov ntsia hlau uas nws cov xov, suab thiab lwm yam haujlwm sib txawv raws li hom pob txha siv:

Cortical screws - tseem hu ua cortical screws - yog tsim los rau kev tuav nruj thiab muab kev ruaj ntseg siab tshaj plaws thaum muab tso rau hauv cov pob txha cortical. Cov ntsia hlau ruaj khov no muaj qhov sib txawv me me, cov xov ntiav ntiav nrog qhov sib nrug ntawm qhov ntev, thiab feem ntau muaj qhov xaus. Cortical screws feem ntau yog 0.059" (1.5 hli) rau 0.177" (4.5 hli) ntev.

Cancellous screws, tsim los kho cov pob txha pob txha, ntev dua thiab muaj qhov sib txawv ntau dua li cortical screws. Cancellous threads raug txiav tob dua thiab dav dav, thiab cov ncej yuav tsum tau threaded tag nrho los yog tsuas yog ib feem threaded. Cov ntsia hlau ntev feem ntau yog 0.138" (3.5 hli) rau 0.256" (6.5 hli).

Kev txaus siab ua cov khoom lag luam hauv Tebchaws Europe thiab Tebchaws Meskas, Nyiv thiab Kaus Lim Qab Teb, Middle East, Southeast Asia tau qhuas ntau.
