Custom Size Needle Application For Special Anatomical Nerve Block

Pain PointsStandard 8G–26G tsau- qhov loj ntawm cov hlab ntsha thaiv cov koob tsis tuaj yeem hloov mus rau cov qauv anatomical tshwj xeeb thiab cov kev xav tau ntawm tus kheej, dhau los ua lub hauv paus rau kev ua haujlwm nyuaj rau cov hlab ntsha. Cov xwm txheej tshwj xeeb xws li cov ntaub so ntswg nqaim, ultra- cov neeg mob rog rog, ultra- cov ntaub so ntswg hauv cov menyuam yaus thiab cov hlab ntsha tortuous muaj cov kev cai nruj ntawm rab koob sab nraud txoj kab uas hla, ntev thiab rigidity. Tsau tus qauv ntau thiab tsawg feem ntau muaj teeb meem xws li cov tuab tuab ua rau cov ntaub so ntswg extrusion, ntev tsis txaus ua rau tsis ua hauj lwm puncture, thiab ntau fineness ua rau tsis zoo stability. Cov kws kho mob tsuas tuaj yeem kho qhov muag tsis pom kev ntawm lidocaine dilution concentration los them rau qhov ntsuas qhov tsis xws luag, uas ua rau muaj kev siv tshuaj loog tsis zoo thiab muaj kev pheej hmoo ntxiv. Qhov tsis muaj tus kheej kev cai loj daws teeb meem txwv txoj kev txhim kho cov tshuaj loog hauv cov xwm txheej nyuaj.

Txoj Cai CoreQhov kev cai loj muaj peev xwm ntawm cov hlab ntsha thaiv koob rhuav tshem qhov kev txwv qhov ntev ntawm cov txheej txheem ruaj khov, paub txog tus kheej hloov kho rau tshwj xeeb anatomical paj thaiv. Kev cia siab rau cov txheej txheem paub tab nrog rau caj dab, swaging, laser txiav thiab electropolishing, cov tuam txhab tuaj yeem kho cov tub ntxhais loj tsis xws li rab koob ntsuas, ntev thiab lub taub hau radian raws li cov neeg siv khoom 2D / 3D kos duab lossis kuaj lub cev. Kev cai- cov koob loj tuaj yeem ua tau raws li qhov sib txawv ntawm cov qauv ntawm cov qauv anatomical complex, nrog rau cov lumen txaus thiab rigidity, tsim cov phiaj xwm sib txuam nrog tus kheej lidocaine dilution concentrations. Qhov sib txawv ntawm cov qauv me me kev sib koom ua ke, qhov kev cai ntau thiab tsawg tau paub txog ib qho - mus rau - ib qho kev hloov kho qhov loj me rau cov xwm txheej tshwj xeeb, kom ntseeg tau qhov tseeb thiab qhov sib txawv ntawm cov tshuaj loog diluted manually, thiab daws qhov teeb meem tsis ua hauj lwm tshuaj loog tshwm sim los ntawm qhov loj me tsis sib haum hauv cov xwm txheej nyuaj.

Kev faib khoom ntaus ntawvKev cai paj ntaub thaiv cov koob tau muab faib ua peb hom kev hloov kho me me rau cov xwm txheej tshwj xeeb. Ua ntej, ultra-ntev tuab kev cai qhov ntau thiab tsawg: ua kom zoo raws li 8G–14G, nrog rau lub cev txuas ntxiv thiab txhim kho rigidity, haum rau ultra- cov hlab ntsha sib sib zog nqus hauv cov neeg mob rog, sib tw nrog 1.8%–2.0% siab- concentration lidocaine. Thib ob, ultra- luv luv ultra- qhov loj me me: hloov kho ntawm 20G–26G hauv paus, nrog lub cev luv luv thiab polished blunt taub, rau cov menyuam yaus thiab ultra-cov ntaub so ntswg ntiav ntiav, sib tw nrog 0.5%–0.7% qis-tso tshuaj. Thib peb, tshwj xeeb - txoj kab uas hla kev cai qhov ntau thiab tsawg: tsis yog - qauv ntsuas qhov ntau thiab tsawg ntawm cov pa gradients, rau qhov sib txawv ntawm qhov nqaim thiab tortuous paj puncture, matched nrog nruab nrab tshwj xeeb -concentration diluted lidocaine. Txhua qhov kev cai ntau thiab tsawg tau txais kev kho mob stainless hlau cov khoom siv thiab nruj terminal sterilization.

Cov Txheej Txheem Ua HaujlwmStandardize qhov kev ua hauj lwm ntawm kev cai loj koob thiab tus kheej lidocaine dilution. Rau ultra- cov hlab ntsha sib sib zog nqus hauv cov neeg mob rog rog, txais kev cai ultra- ntev 10G–12G tuab koob, npaj 1.8%–2.0% siab-concentration lidocaine los ntawm 20ml proportional dilution, thiab xyuas kom meej tag nrho kev nkag mus ntawm cov ntaub so ntswg sib sib zog nqus kom tiav cov hlab ntsha. Rau cov menyuam mos thiab lub ntsej muag zoo nkauj thaiv, xaiv kev cai 27G–30G ultra- koob luv luv, dilute 0.5%–0.7% qis- tshuaj loog ua kom muaj zog, thiab txo qis kev txhaj tshuaj kom txo qis cov nqaij mos. Rau qhov nqaim anatomical gap block, siv cov kev cai hloov pauv - koob loj, kho qhov sib piv ntawm dilution raws li qhov tseeb puncture resistance, thiab xyuas kom meej cov tshuaj diffusion nyob ib ncig ntawm lub paj hlwb. Txheeb xyuas qhov ntsuas qhov loj me ua ntej ua haujlwm kom phim qhov xwm txheej thiab kev xav kom raug.

Tiag -Kev Paub Txog Ntiaj TebTertiary tsev kho mob nyuaj tshuaj loog cov ntaub ntawv qhia tau hais tias kev cai loj hlab ntsha thaiv koob nce qhov kev vam meej ntawm complex scenario paj hlwb los ntawm ntau tshaj 45%. Kev cai ultra- ntev ntev koob daws cov teeb meem ntawm qhov tsis txaus puncture qhov tob thiab tsis muaj kev ruaj ntseg ntawm cov qauv koob hauv cov neeg mob rog, koom tes nrog siab -concentration lidocaine kom ua tiav cov tshuaj loog ruaj khov. Kev cai ultra- koob luv luv zoo heev txo qhov kev raug mob ntawm cov menyuam yaus lub paj hlwb, thiab sib npaug qis -cov tshuaj muaj zog diluted zoo kom tsis txhob muaj kev phiv. Tus kheej qhov kev hloov kho qhov loj me ua rau ib qho tsis xws luag ntawm tus qauv loj gradients, zoo kawg nkaus hloov mus rau ntau hom kev sib txawv ntawm cov neeg mob, thiab tau dhau los ua cov cuab yeej tseem ceeb rau niaj hnub kev tshuaj loog.

XausKev cai loj ntawm cov hlab ntsha thaiv cov koob nthuav dav qhov loj me ntawm cov cuab yeej kho mob paj hlwb, paub txog xoom- dig muag- qhov chaw hloov kho rau qhov xwm txheej tshwj xeeb anatomical. Kev hloov kho qhov loj me ntawm tus kheej daws cov teeb meem tseem ceeb ntawm tus qauv me me tsis sib haum hauv kev ua haujlwm nyuaj, thiab cov ntaub ntawv raug txuam nrog kev kho lidocaine dilution schemes. Kev sib xyaw ua ke ntawm cov qauv gradient qhov ntau thiab tsawg thiab cov kev cai loj ua kom tiav qhov ntev ntawm cov hlab ntsha thaiv cov twj paj nruag, nteg lub hauv paus ruaj khov rau tag nrho cov kev pabcuam thiab kev kho kom zoo ntawm cov tshuaj loog meej meej.

Outlook & Cov lus qhiaCov neeg tsim khoom yuav tsum txhim kho qhov muaj peev xwm hloov kho sai ntawm me me -batch tshwj xeeb qhov ntau thiab tsawg thiab ua kom luv luv ntawm kev txiav txim ntawm cov koob kev cai. Cov tsev kho mob yuav tsum sau cov ntsiab lus ntawm qhov zoo tshaj plaws kev cai qhov loj me rau cov xwm txheej nyuaj sib txawv thiab tsim cov txheej txheem kev hloov kho tus qauv. Ntxiv dag zog rau tus kws kho mob kev cob qhia ntawm kev cai loj koob ua haujlwm thiab tus kheej dilution txuam kev txawj ntse. Nruam ntxiv cov kev cai loj parameter hom hloov mus rau ntau txoj kev kho mob tshuaj loog xav tau.
