Technical field
[0001] tam sim no invention belongs rau cov cuab yeej kho mob phais, tshwj xeeb tshaj yog rau ib qho khoom siv rau kev tshem tawm ib rab koob kho mob.
Cov cuab yeej siv tom qab
[0002] hlau screws feem ntau yog siv rau orthopedic fixation.Hauv kev kho mob, kev txhim kho pob txha yog feem ntau tawg (sliding) rau tes.Thaum cov ntsia hlau tawg (sliding) tshwm sim, kev ua haujlwm raug yuam kom nres, thiab tag nrho cov txheej txheem kho pob txha yuav tsum pib los ntawm kos.Kev tshem tawm ntawm cov ntsia hlau tawg (sliding) yog ib qho teeb meem nyuaj heev, uas yuav siv sij hawm thiab siv zog.Cov cuab yeej ib txwm siv rau kev tshem tawm cov ntsia hlau tawg yog lub voj voos, uas muaj cov ntsia hlau tshem tawm tsis zoo, siv sijhawm ntev, thiab muaj kev puas tsuaj loj rau cov pob txha.Ntxiv mus, cov ntsia hlau yuav tsum tau muab tshem tawm tom qab lub phaj steel raug tshem tawm tag.Cov pob txha qub tsis tuaj yeem rov qab siv tau, thiab cov phaj hlau yuav tsum tau txav mus los, uas ua rau muaj kev cuam tshuam loj rau tag nrho kev ua haujlwm, ua rau muaj kev pheej hmoo ntawm iatrogenic refracture, ua rau lub sijhawm ua haujlwm, thiab ua rau cov ntshav ntau ntxiv rau cov neeg mob, tus nqi ntawm postoperative kab mob nce.Qee tus kheej tsim cov ntsia hlau rhuav tshem cov ntsia hlau tsis zoo thiab tsis ua tiav lub hom phiaj ntawm kev yooj yim thiab ceev.
Summary ntawm inventi
[0003] txhawm rau txhawm rau kov yeej qhov tsis zoo ntawm kev siv tsis yooj yim ntawm cov ntsia hlau tawg uas twb muaj lawm, qhov kev tsim kho tam sim no muab cov ntsia hlau tawg orthopedic thiab nws txoj kev siv.Lub orthopedic tawg ntsia thawv extractor tsis tsuas yog yooj yim mus nrhiav kom raug, tab sis kuj muaj me ntsis kev puas tsuaj rau lub cev thaum lub sij hawm tshem tawm cov txheej txheem.[0004] cov kev daws teeb meem tau txais los ntawm qhov kev tsim kho tam sim no los daws cov teeb meem kev lag luam yog: ib qho orthopedic tawg ntsia thawv extractor, uas yog tus cwj pwm los ntawm: nws yog tsim los ntawm ib tug laum phau ntawv qhia, ib tug laum ntsis thiab ib tug ntsia hlau extractor.Ib qho kawg ntawm tus pas nrig ntawm lub laum phau ntawv qhia yog ib qho kev taw qhia, thiab lwm qhov kawg yog nruab nrog lub Hoobkas zoo li tus taw qhia lub taub hau.Kab rov tav ntu ntawm phau ntawv qhia lub taub hau yog muab nrog ib qho kev qhia lub qhov rau kev txhim kho ib tug laum me ntsis, thiab inclined seem ntawm lub taub hau phau ntawv qhia yog muab nrog ib tug auxiliary positioning pin, tus ntsia thawv extractor yog T-puab, sab sauv kawg ntawm tus ntsia thawv extractor pas nrig yog nruab nrog ib tug ntsia thawv extractor kov perpendicular rau nws, lub qis kawg yog ib tug truncated conical ntsia hlau extractor xov lub taub hau, thiab nws xov kev taw qhia yog rov qab xov, piv txwv li sab laug-tes xov.
[0005] lub auxiliary positioning pin yog welded thiab tsau rau ntawm lub taub hau qhia.
[0006] lub koob qhov chaw pabcuam yog threadedly txuas nrog lub taub hau qhia.
[0007] tus kov ntawm tus ntsia thawv extractor yog nyob rau hauv cov duab ntawm lub tes tsho, thiab tus tuav pas nrig ntawm tus ntsia thawv extractor yog ntsia rau hauv lub tes tsho.
[0008] xov lub taub hau ntawm lub truncated conical ntsia thawv extractor, pem hauv ntej kawg ntawm lub taub hau xov yog 0.5-1 hli me dua lub cheeb ntawm lub laum lub qhov, lub rear kawg yog 1-2 hli loj tshaj txoj kab uas hla ntawm lub laum qhov, thiab cov xov ntev yog 15-25mm.
[0009] ib txoj hauv kev siv cov ntsia hlau tawg orthopedic, uas yog tus cwj pwm hauv nws feem ntau suav nrog cov kauj ruam hauv qab no:
[0010] A. positioning: dlhos qhov kev qhia ntawm lub laum phau ntawv qhia nrog lub taub hau ntawm tus ntsia thawv tawg, thiab kho qhov kev qhia lub qhov kom nyob rau hauv tib txoj kev raws li tus ntsia thawv tawg, [0011] B. drilling: muab lub laum ntsis ntawm lub tshuab hluav taws xob laum rau hauv qhov kev taw qhia, pib lub tshuab hluav taws xob laum rau ntawm tus ntsia hlau tawg, thiab qhov drilling qhov tob yog [0012] C. noj cov ntsia hlau tawg: ntxig cov ntsia hlau taub hau ntawm cov ntsia hlau ntsia hlau extractor rau hauv lub qhov laum, tig ntsia hlau ntsia thawv extractor mus rau sab laug, uas yog, tig lub ntsia hlau ntsia thawv extractor counterclockwise, thiab xov rau sab nraum qab ntawm tus ntsia thawv tawg lub qhov, tus ntsia thawv extractor yog nyob ze rau cov ntsia hlau tawg.Txij li cov xov ntawm cov ntsia hlau taub hau ntawm cov ntsia hlau ntsia hlau extractor yog cov xov sab laug ntawm cov ntsia hlau tawg, cov ntsia hlau tawg tuaj yeem raug ntsia hlau tawm ntawm tib neeg lub cev thaum lub sij hawm sab laug tes, piv txwv li counterclockwise kev sib hloov.
[0013] Kev siv txoj kev ntawm cov kev tsim kho tam sim no yog los qhia qhov kev qhia ntawm lub taub hau tawg, muab lub laum me ntsis ntawm hluav taws xob laum rau hauv qhov kev taw qhia, pib lub tshuab hluav taws xob laum rau ntawm cov ntsia hlau tawg, thiab tom qab ntawd ntxig cov ntsia hlau taub hau ntawm cov ntsia hlau ntsia hlau extractor rau hauv lub qhov laum kom tig sab laug (counterclockwise) cov ntsia hlau ntsia hlau extractor.Lub nraub qaum ntawm lub qhov ntsia hlau tawg yog rov qab threaded, thiab tus ntsia thawv extractor yog nyob ze rau ntawm tus ntsia thawv tawg, Txij li cov xov ntawm cov ntsia hlau taub hau ntawm cov ntsia hlau ntsia hlau extractor yog cov xov sab laug rov qab rau cov xov ntawm cov ntsia hlau tawg. , cov ntsia hlau tawg tuaj yeem raug ntsia hlau tawm ntawm tib neeg lub cev thaum lub sij hawm tig sab laug (tso rov ua dua clockwise).Txij li thaum lub auxiliary fixed koob ntawm phau ntawv qhia drilling yog txuas nrog lub taub hau ntawm cov xov, nws qhov ntev tuaj yeem hloov kho raws li qhov xav tau ntawm qhov chaw phais, thiab lub kaum sab xis ntawm lub qhov taub ntawm lub qhov taub tuaj yeem kho tau yooj yim dua thiab raug kom ntseeg tau tias qhov kev taw qhia drilling yog ua raws li cov kab nruab nrab ntawm cov ntsia hlau tawg, kom txo tau qhov kev puas tsuaj rau lub cev thaum lub sijhawm tshem tawm cov ntsia hlau thiab txo qhov mob ntawm tus neeg mob.
[0014] cov txiaj ntsig zoo ntawm qhov kev tsim kho tam sim no yog cov ntsia hlau tawg tuaj yeem raug muab tso rau hauv, tho thiab tshem tawm.Cov cuab yeej tuaj yeem kho lub kaum sab xis ntawm qhov kev qhia ruaj khov raws li qhov xav tau ntawm qhov chaw phais kom paub tseeb tias qhov kev taw qhia drilling yog raws li qhov nruab nrab ntawm cov ntsia hlau tawg, txo qhov kev puas tsuaj rau lub cev thaum lub sij hawm tus ntsia thawv noj thiab txo. qhov mob ntawm tus neeg mob.
