Dab tsi yog Cancellous Bone Screw
Dec 19, 2022
Peb cov ntsia hlau no yog hu ua screws rau kev tshaj lij thiab koom nrog cov khoom siv kho mob:
4mm, qhia xov loj, 12-50mm, qhia 12-50mm ntev, lwm yam zoo sib xws.
Hollow self-tapping compression ntsia hlau thiab daim ntawv thov txoj kev ntawd. Lub hollow pressurized self-tapping ntsia hlau muaj xws li tus ntsia thawv hau (1), tus ntsia thawv lub cev (2) thiab tus ntsia thawv taub (5). A los ntawm qhov (3) yog muab raws li axis kab ntawm cov ntsia hlau, thiab lub koob taub yog ib tug self-tapping ntsis. Rau patellar tawg, qhib kev txo qis yog thawj zaug siv, thiab tom qab ntawd Kirschner hlau tau siv rau kev kho, hollow nws tus kheej tapping ntsia hlau tau siv raws li Kirschner hlau, thiab tom qab ntawd Kirschner hlau raug tshem tawm thiab xaim tau siv rau kev kho qhov nro ntawm lub hollow. self-tapping ntsia hlau. Piv nrog rau Kirschner hlau fixation, lub zog thiab txhim kho cov nyhuv ntawm cov invention yog ho txhim khu kev qha, thiab ib tug nro band yog tsim nyob rau saum npoo ntawm lub patella nrog cov hlau xaim hla lub hau ntswj hollow, thiaj li mus cuag ruaj khov kho.
Cancellous pob txha screws yog cov cuab yeej kho mob orthopedic. Cov ntsia hlau muaj cov ntsia hlau, thiab lub hauv ntej kawg ntawm cov ntsia hlau yog muab nrog cov pob txha pob txha, uas yog tus cwj pwm los ntawm cov xov rov qab kawg tig nyob rau hauv tib txoj kev raws li lub hauv ntej kawg cancellous pob txha xov ntawm cov ntsia hlau sab hauv lub taub hau ntsia hlau. Nws qhov zoo dua yog txhawm rau txhim kho qhov compression ntawm cov ntsia hlau, sau qhov sib txawv sab laug los ntawm cov xov pem hauv ntej, tiv thaiv lub sijhawm ntev ntawm cov ntsia hlau rov qab.
