Prototype Iteration Thiab Coupling Optimization Hauv Pob Txha Biopsy Devices

Nyob rau hauv cov pob txha biopsy, txo qis cov txheej txheem txheej txheem tseem yog tus tsav tsheb tseem ceeb ntawm kev tsim kho tshiab. Ib txwm muaj ntau- kauj ruamkoob tshuaj biopsyyuav tsum tau rov hais dua, tshem tawm, thiab sib pauv cov khoom, ncua kev phais, ua rau muaj kev raug mob, thiab ua kom muaj kev pheej hmoo kis mob. CovIb - kauj ruam - koobLub tswv yim tau tshwm sim los hais txog qhov no, aiming kom ua tiav medullary nkag mus thiab cov qauv retrieval nyob rau hauv ib qho kev ntxig. Kev txhais cov tswv yim no rau hauv kev ua lag luam- cov khoom npaj, txawm li cas los xij, hinges ntawm cov chaw tsim khoom muaj kev txawj ntse hauv cov qauv iteration thiab coupling optimization.

Lub ntsiab complexity ntawm ib tug - kauj ruam tsim nyob rau hauv lub sophistication ntawm lubcoupling ntaus ntawv. Txhawm rau ua kom tiav ib qho - kev ua haujlwm, rab koob feem ntau koom nrog cov txheej txheem sab hauv, xws li retractable stylets, sab - qhib qhov rais biopsy, thiab tshwj xeeb locking nta. Thaum ntxov-theem prototyping, cov tuam txhab lag luam ntsib qhov kev sib tw tseem ceeb ntawm kev sib koom ua ke cov haujlwm no hauv qhov chaw kaw ntawm rab koob cannula thaum ua kom muaj kev ntseeg tau ntawm cov qauv thiab kev ua haujlwm yooj yim.

Peb R & D ua raws li nruj me ntsis rau tsimKhoom siv thiab txheej txheem. Pibfunctional prototype manufacturingSiv 3D luam ntawv thiab precision CNC machining los tsim ntau yam sib txuas ua ke. Txhua tus qauv tsom rau cov ntsiab lus mob tshwj xeeb- qee qhov tseem ceeb ua ntej cov qauv qauv tawm los, lwm tus tsom mus rau txo qis cov ntaub so ntswg raug mob.

Tom qab ntawdpuncture xeemhauv vitroua pov thawj tseem ceeb. Prototypes tau raug kuaj cyclically ntawm cov qauv pob txha hluavtaws uas siv siab - lub koob yees duab ceev thiab thauj cov hlwb kom ntes cov pob txha nkag mus rau hauv lub cev. Cov kev tshawb fawb sib piv tau qhia tias cov qauv ua ntej tau raug kev txom nyem los ntawm "dhau- nkag mus" ntawm cov stylet raws li kev ua txhaum ntawm cortical vim muaj kev cuam tshuam inertial nyob rau hauv lub coupling mechanism, nquag clogging lub qhov rais sampling nrog cov pob txha khib nyiab. Hais txog qhov no yuav tsum tau tsim kho tshiab ntawm geometry.

Los ntawm kev sim dav dav, pebtau txais cov qauv ntawm qhov ntev geometriccuam ​​tshuam kev ua haujlwm. Cov ntaub ntawv tsom xam pom qhov coefficient ntawm kev sib txhuam ntawm stylet thiab cannula, sab hauv lub caij nplooj ntoos hlav preload, thiab lub kaum sab xis raws li peb qhov tseem ceeb sib txawv. Raws li cov kev xav no, pebtxiav txim siab cov kev hloov uas tsim nyog: optimizing lub stylet txheej txheej kom txo tau kev sib txhuam, recalibrating lub caij nplooj ntoos hlav tsis rau softer recoil, thiab redesigning txiav npoo kom txo breakthrough kuj.

Tshaj li mechanics,Ergonomie(ergonomics) yog lub hauv paus rau kev kho kom zoo nkauj. Ib qho - cov koob kauj ruam feem ntau muaj qhov ua rau - cov tes tuav. Thaum qhov kev ntsuam xyuas qhov muag tsis pom los ntawm cov kws kho mob, cov lus tawm tswv yim hais txog kev tuav xis nyob, ua rau muaj kev ntxhov siab, thiab kev tawm tswv yim tactile clarity qhia rov qab kho dua. Kov curvature tau hloov kho kom haum nrog tes physiology, thiab tiv thaiv -slip texturing tau zoo. Thaum kawg, tus qauv iterated tsis tsuas yog ua tau raws li cov qauv ntsuas kev ua tau zoo tab sis kuj ua tiavoptimum tuav. Qhov no tau tsav los ntawm kev kho mob, kev tshawb fawb nruj mus kom ze rau qhov kev hloov kho txuas ntxiv txuas ntxiv embodies tus nqi tseem ceeb ntawm cov khoom siv kho mob siab tshaj - kawg.
