Technical Q&A rau Pab Pawg Txhim Kho Kom Zoo

Q: Yuav ua li cas tsis zoo-lub kaum sab xis threads tiv thaiv teeb tsa rov qab-tawm piv rau cov qauv ca threads?

A: Standard ca los yog V-threads tawm sab nraud radial quab yuam tawm tsam sab hauv phab ntsa ntawm lub taub hau ntsia hlau (tulip) thaum nruj rau qhov kawg torque. Nyob rau hauv siab cyclic mechanical stress, no radial force ua rau cov phab ntsa tulip nthuav me ntsis los yog 'splay.' Thaum splay tshwm sim, cov xov interlocking tee, cia lub teeb ntsia hlau rov qab. XC Medico's negative-angle buttress thread nta ib tug downward thiab sab hauv geometry. Thaum siv lub zog torque, cov xov rog tiag tiag rub cov phab ntsa tulip sab hauv, xauv lub teeb ntsia hlau nruj nreem tiv thaiv tus pas nrig thiab tshem tawm tag nrho cov splay-driven tsim tsis ua haujlwm.

Q: Vim li cas lub kaw lus sib txuas yuav tsum tau ua nyob rau hauv ntu ntev tom qab kho kom tiv thaiv pas nrig zawv zawg?

A: Independent parallel rods tsuas yog tso siab rau kev sib txhuam hauv zos ntawm tus kheej pedicle screws. Yog tias tus neeg mob muaj cov pob txha osteopenic zoo, rov ua dua lub cev sib hloov tuaj yeem ua rau lub ntsej muag me me ntawm cov ntsia hlau taub hau, degrading qhov kev sib txhuam hauv zos tuav lub sijhawm. Integrating adjustable cross-connectors txuas rau sab laug thiab txoj cai rods rau hauv ib tug nruj quadrangular box ncej. Qhov kev sib txuas ntau qhov kev sib txuas no hloov cov kev ntxhov siab thoob plaws tag nrho cov tsim, ua rau tus pas nrig longitudinal zawv zawg mechanically tsis yooj yim sua txawm tias ib qho kev sib txuas ntawm ib qho kev sib tshuam micro-fretting hnav.
