Artificial hip sib koom simulation kuaj tshuab

1. Technical field

Cov qauv siv hluav taws xob cuam tshuam nrog lub tshuab hluav taws xob sib koom ua ke, tshwj xeeb tshaj yog rau lub tshuab hluav taws xob sib koom ua ke rau kev simulating lub xeev cov lus tsa suab thiab kev ntxhov siab ntawm acetabulum ntawm tib neeg lub duav sib koom.

2. Cov cuab yeej siv tom qab

Lub duav pob qij txha yog qhov sib koom ua ke nrog cov kev ntxhov siab tshaj plaws hauv tib neeg lub cev, thiab nws kuj yog ib qho chaw ua rau cov kab mob sib koom ua ke, xws li cov kab mob raug mob, kab mob ischemic necrotic, kab mob degenerative, thiab kab mob inflammatory thiab neoplastic. Thoob plaws ntiaj teb, ntau dua 600,000 cov neeg mob tau txais kev phais hloov lub duav txhua xyoo. Nrog rau txoj kev loj hlob ntawm cov cuab yeej kho mob niaj hnub no, muaj ntau thiab ntau tus neeg mob ntawm cov pob qij txha hloov pauv. Kev hnav thiab tsim kua muag ntawm cov pob qij txha tuaj yeem tsis tsuas yog ua rau kev puas tsuaj ntawm kev sib koom tes sib koom tes nws tus kheej thiab ua rau lub tshuab tsis ua haujlwm tab sis kuj tsim cov khoom siv ntau heev los ua kom osteolysis nyob ib ncig ntawm lub prosthesis. Cov kev tshawb fawb tau pom tias lig loosening ntawm cov pob qij txha pob txha muaj feem cuam tshuam nrog kev nce ntxiv ntawm cov khoom hnav (cov khib nyiab) thiab cov tshuaj tiv thaiv txawv teb chaws nws ua rau. Cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau ua ntau yam kev tshawb fawb txog kev tsim thiab txheej txheej ntawm cov khoom siv dag zog sib koom ua ke (Hip Universal Rotation Poob Wax Castings), cia siab tias yuav txo qis hnav thiab hnav cov khib nyiab los ntawm kev hloov cov khoom sib txuam, tab sis cov txiaj ntsig tsis zoo. . Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau kawm txog lub zog, nkag mus, thiab hnav cov pob qij txha pob qij txha. Muaj tsawg tsawg cov ntaub ntawv qhia txog kev txhim kho ntawm lub duav sib koom ua ke simulation simulation tshuab, thiab tseem muaj qee qhov sib txawv piv nrog cov kev tshawb fawb txawv teb chaws ntawm simulation simulation tshuab.

Tam sim no, lub tshuab hluav taws xob sib koom ua ke simulation simulate tuaj yeem simulate lub xeev cov lus tsa suab thiab kev ua haujlwm ntawm tib neeg lub duav sib koom ua ke kom raug raws li qhov ua tau hauv chav kuaj ib puag ncig thiab tuaj yeem ua rau kev sib txhuam mechanism thiab hnav daim ntawv ntawm kev sib koom ua ke hauv kev sim hauv cov txheej txheem xeem. ua raws li qhov tseeb Nws yog raws li nyob rau hauv tej yam kev mob ntawm kev siv thiaj li hais tias cov biomechanical kev ua tau zoo ntawm cov khoom sib koom ua ke tuaj yeem kawm thiab kuaj kom raug thiab ntseeg tau.

3. Cov ntsiab lus ntawm invention:

Cov qauv siv hluav taws xob yog muab cov khoom siv dag zog sib koom ua ke simulation simulation tshuab. Lub tshuab kuaj paub txog qhov txuas ntxiv \ flexion (FE) lossis adduction \ abduction (AA), kev sib hloov sab hauv \ sab nraud kev sib hloov ntawm tib neeg lub duav sib koom ua ke hauv lub xeev bionic los ntawm tsib lub tswv yim. Rotary (IER) txav, lub tshuab ntsuas muaj cov yam ntxwv ntawm kev txhim kho yooj yim, kev ua tau zoo, muaj zog nthuav dav, thiab kev ua haujlwm siab.

Cov txheej txheem ntawm cov qauv siv hluav taws xob yog: lub tshuab hluav taws xob sib koom ua ke simulation simulation tshuab, suav nrog lub thav duab, lub viav vias mechanism, hloov tau yooj yim loading mechanism, kev sib hloov mechanism, thiab lub duav sib koom ua ke mechanism, thiab yog tus cwj pwm los ntawm cov cuab yeej rau viav vias. hip yog ntsia rau hauv qab ntawm tus ncej. Lub viav vias mechanism ntawm lub qhov (socket) xeem daim, lub duav sib koom fixture mechanism yog ntsia rau ntawm lub viav vias mechanism, thiab lub duav sib koom fixture mechanism yog tsau rau ntawm lub rooj khib, thiab txuas nrog kev sib hloov mechanism los ntawm kev sib kis. Lub sab sauv kawg ntawm lub duav sib koom fixture mechanism yog kev cob cog rua rau lub saj zawg zog loading mechanism, thiab saj zawg zog loading mechanism kis tau los ntawm lub lever bracket yog tsau rau ntawm lub rooj khib.

Lub tshuab ua haujlwm hloov tau muaj xws li lub caij nplooj ntoos hlav molded, lub siab lub cev muaj zog thiab lub taub hau ntsia hlau, lub fulcrum bracket, lub zog, thiab lub caij nplooj ntoos hlav pwm yog teem rau ntawm lub hau ntswj ntawm lub siab lub cev muaj zog, qis kawg yog txuas nrog lub tes tsho txav, sab sauv kawg yog txuas nrog lub tes tsho ruaj, thiab lub sab sauv kawg ntawm lub tes tsho ruaj yog txuas nrog. Lub lever yog movable txuas nrog lub kauj bracket.

Qhov sib piv ntawm qhov kev ncua deb ntawm qhov txuas kawg ntawm lub kauj thiab qhov ruaj khov bushing mus rau qhov chaw ntawm kev sib hloov ntawm lub kauj bracket thiab qhov kev ncua deb ntawm kev sib txuas kawg ntawm lub kauj thiab lub duav sib koom clamp mechanism thiab qhov chaw ntawm kev sib hloov ntawm lub kauj bracket yog 2.5:1.

Lub rooj zaum acetabular yog npaj nyob rau hauv lub viav vias mechanism, thiab ib tug inclined nto yog teem nyob rau sab sauv kawg ntawm lub acetabular khob lub rooj, thiab lub inclined lub kaum sab xis ntawm inclined nto yog 23 degree.

Cov txiaj ntsig zoo ntawm cov qauv siv hluav taws xob yog:

Lub tshuab ntsuas hluav taws xob ntawm cov qauv siv hluav taws xob tuaj yeem paub txog qhov txuas ntxiv \ flexion (FE) lossis adduction \ abduction (AA), kev sib hloov sab hauv \ sab nraud rotation (IER) txav ntawm tib neeg lub duav sib koom ua ke hauv lub xeev bionic. Ib txhij ua tiav ob hom kev sib txawv hauv qab no:

(1) Multi-directional compound hom: compounded los ntawm lub viav vias mechanism thiab rotary mechanism, nws muaj peev xwm paub txog kev txav mus rau peb cov lus qhia (FE, AA, IER).

(2) Ib-txoj kev hom: uas yog, kev sib hloov ntawm lub viav vias mechanism los yog kev sib hloov mechanism nyob rau hauv ib qho kev taw qhia, thiab lub zog ntawm lub xeev no tsuas yog ua tiav los ntawm lub zog ntawm ib tug mechanism.

Cov qauv siv hluav taws xob txais yuav lub zog simulated los ntawm peb-axis kuaj tshuab kom ze rau qhov tseeb dua li ob-axis ib qho, thiab cov txiaj ntsig tau txais kev sim tau zoo dua nrog cov ntaub ntawv kho mob. Lub tshuab kuaj no muaj cov yam ntxwv ntawm kev txhim kho yooj yim, kev ua tau zoo, muaj zog nthuav dav, thiab kev ua haujlwm siab.
