Anatomical Puncture Principple Thiab Clinical Application Logic Of Spinal Needles

Technical Nrov Science los ntawm Kev Kho Mob Stainless Hlau Puncture Needle Chaw Tsim Tshuaj

Lumbar puncture sawv cev rau qhov tseem ceeb ntawm kev kuaj mob tsawg kawg nkaus thiab kho cov txheej txheem hauv neurology thiab tshuaj loog, dav siv rau kev kuaj mob ntawm lub hauv nruab nrab paj hlwb tsis meej, txhav txhav thiab kev tswj hwm intracranial siab. Cov16G-27G kev kho mob qib stainless hlau spinal koobua raws li cov cuab yeej ua haujlwm tseem ceeb rau cov txheej txheem zoo li no. Kev txhawb los ntawm cov khoom R & D thiab kev soj ntsuam kev sib koom tes, cov kws tshaj lij puncture koob manufacturers sib sib zog nqus txhais cov ntsiab lus anatomical nkag mus rau hauv lub hauv paus ntsiab lus, kev phais kev ua haujlwm thiab cov cuab yeej ntsuas qhov tseem ceeb ntawm cov leeg txha caj qaum, pab cov neeg ua haujlwm kho mob ua haujlwm ua haujlwm thiab txhim kho kev phais mob.

Standard lumbar puncture ua raws li cov ntaub so ntswg nkag mus rau hauv txoj kev, uas ua rau txoj kev ua hauj lwm ntawm tus txha caj qaum. Cov koob yuav tsum tau ua ntu zus los ntawm ntau txheej ntawm cov ntaub so ntswg lumbar kom ncav cuag thaj tsam ntawm lub hom phiaj - qhov chaw subarachnoid. Ua tiav kev nkag mus ua ntu zus pib nrog cov epidermis thiab cov ntaub so ntswg subcutaneous, uas yog xoob nrog tsis muaj zog. Tom qab ntawd, rab koob hla los ntawm supraspinous ligament thiab interspinous ligament. Cov ligaments txuas lub lumbar vertebrae nrog kev ntxhib los mos, tsim kom muaj kev tiv thaiv tsis tu ncua. Cov teeb meem tom qab, ligamentum flavum, yog cov txheej txheem tseem ceeb tshaj plaws nrog cov ntaub so ntswg ntom ntom thiab siab tshaj plaws. Cov kws kho mob tuaj yeem hnov ​​​​qhov pom tseeb tam sim ntawd poob ntawm kev tawm tsam thaum nkag mus, ib qho teeb meem tseem ceeb uas lees paub qhov kev ua tiav zoo.

Tom qab tawg los ntawm ligamentum flavum, koob nkag mus rau hauv qhov chaw epidural, dura mater thiab arachnoid mater txuas ntxiv mus, thiab thaum kawg mus txog qhov chaw subarachnoid uas muaj cov kua dej cerebrospinal, lub hom phiaj tseem ceeb ntawm lumbar puncture. Thaum nyob hauv qhov chaw, cov kws kho mob tuaj yeem muab cov kua dej cerebrospinal rau kev kuaj sim, ntsuas intracranial siab, lossis txhaj tshuaj loog thiab cov tshuaj kho mob kom paub txog kev kuaj mob thiab kev kho mob. Tus qauv tsim ntawm 16G-27G kev kho mob stainless hlau spinal koob tau ua tiav raws li txoj cai nkag mus rau hauv lub cev. Smooth polished shafts thiab cov lus qhia hauv av zoo haum rau cov ntaub so ntswg sib txawv thaum lub sij hawm nkag mus, zam cov ntaub so ntswg laceration thiab kev puas tsuaj rau cov hlab ntsha thiab cov hlab ntsha.

Ob txoj kev xaiv cov lus qhia ntxiv ua kom txaus siab ntau yam kev xav tau puncture. Lub Quincke Point muab lub peev xwm nkag tau zoo rau cov neeg mob uas muaj cov ligaments tuab thiab cov ntaub so ntswg tuab, ua kom lub sijhawm ua haujlwm ntev thiab ua kom muaj txiaj ntsig zoo rau cov kev phais nyuaj. Pencil Point ua rau muaj kev sib tsoo me ntsis yam tsis muaj kev txiav cov pob txha mos ntau dhau thiab cov hlab ntsha me me, txo cov teeb meem xws li cov kua cerebrospinal leakage thiab tom qab- mob taub hau ntev, haum rau niaj hnub minimally invasive puncture as well as pediatric and geriatric surgeries. Tus qauv 90mm ntev npog qhov tob rau feem ntau cov neeg laus lumbar punctures, thiab customized lengths haum rau cov neeg mob nrog tshwj xeeb lub cev hom thiab puncture txoj hauj lwm.

Los ntawm txoj kev xav, manufacturers optimize cov khoom cov ntsiab lus raws li anatomical puncture qauv. Kev kho mob stainless hlau shafts tau txais daim iav polishing kom ua tiav kev sib txhuam coefficient qis rau kev ntxig thiab tshem tawm thiab txo qis kev raug mob rau cov ntaub so ntswg. Txawm tias phab ntsa thickness guarantees ruaj khov mechanical kev ua tau zoo yam tsis muaj kev sib txawv thaum kev nce qib. Gradient outer diameters match tissues of different compactness levels: thick needles for dense ligaments and thin needles for delicate fragile tissues to fully satisfy clinical anatomical operation requirements.

Hauv kev xyaum kho mob, sib piv cov cuab yeej nrog cov qauv anatomical yog qhov tseem ceeb los txo qhov kev pheej hmoo ntawm kev phais. Tsim nyog tus qauv 16G-27G spinal koob haum rau lub lumbar puncture anatomical txoj kev zoo kawg nkaus, pab cov neeg ua haujlwm kho mob txiav txim qhov tob tob los ntawm tactile tawm tswv yim thiab cerebrospinal kua outflow thiab zoo heev txhim kho cov lag luam ua tau zoo. Raws li cov kws tshaj lij kev lag luam, peb tsis tu ncua iterate cov khoom lag luam nyob rau hauv kev kho mob anatomical xav tau, optimize ntswj kev sib tsoo cov tswv yim thiab ncej neeg kho tshuab cov qauv, thiab muab kev nyab xeeb, zoo dua thiab kho kom zoo zoo spinal puncture instruments rau cov tsev kho mob thoob ntiaj teb.
