Lumbar puncture thiab spinal anesthesia yog cov haujlwm niaj hnub ua haujlwm hauv neurology thiab tshuaj loog, tab sis cov teeb meem tom qab phais tas ib txwm yog teeb meem tseem ceeb txwv kev kho mob hauv tsev kho mob. Cov teeb meem uas tshwm sim los ntawm post- lumbar puncture mob taub hau thiab cauda equina paj hlwb raug mob tsis tsuas yog cuam tshuam rau cov neeg mob cov kev ua haujlwm rov qab ua haujlwm, tab sis kuj ua rau muaj kev pheej hmoo ntawm kev tsis sib haum xeeb. Lub siab - zooatraumatic mem hluav point spinal koobmuab los ntawm cov kws tshaj lij cov tuam txhab tuaj yeem tiv thaiv ntau yam teeb meem tom qab kev phais thiab nqa cov txiaj ntsig zoo ntawm - cov kev daws teeb meem rau cov txheej txheem thiab kev ua haujlwm ntawm tus txha caj qaum tsawg tsawg.
Tom qab- lumbar puncture headache yog qhov tshwm sim ntau tshaj plaws tom qab kev phais mob, nrog rau qhov tshwm sim ntau hauv kev ua haujlwm puncture. Lub hauv paus pathogenesis yog qhov txo qis ib ntus ntawm intracranial cerebrospinal kua siab los ntawm intraoperative cerebrospinal kua poob. Tom qab lub dural fiber raug txiav los ntawm cov koob ntse ntse, lub qhov txhab tsis tuaj yeem raug kaw sai sai, ua rau cov kua cerebrospinal tsis tu ncua. Kev mob taub hau raug mob hnyav yuav cuam tshuam rau tus neeg mob so thiab rov zoo. Feem ntau mob taub hau me me tuaj yeem txo tau los ntawm kev rov ua dej thiab so hauv 1 mus rau 2 hnub, tab sis qee tus neeg mob yuav muaj mob taub hau tsis tu ncua, uas yuav tsum tau kuaj mob ntxiv thiab pab kho mob, ua rau tus neeg mob mob thiab lub nra hnyav ntxiv.
Cov chaw tsim tshuaj paus atraumatic mem hluav point spinal needle fundamentally optimizes the complex tiv thaiv mechanism. Lub blunt mem hluav taub siv lub cev sib cais puncture hom, uas yuav tsis txiav cov dural thiab subcutaneous fibrous cov ntaub so ntswg. Lub qhov txhab puncture yog me me thiab tsis tu ncua, thiab cov ntaub so ntswg fibrous tuaj yeem rov qab los thiab kaw sai sai tom qab rab koob raug rho tawm, ua haujlwm zoo thaiv cov kua dej cerebrospinal thiab tswj kom ruaj khov intracranial siab. Cov ntaub ntawv thov kev kho mob qhia tau hais tias cov khoom lag luam tuaj yeem txo qhov tshwm sim tom qab - mob taub hau lumbar puncture, thiab ob peb cov tsos mob me me uas tshwm sim yog luv luv thiab yooj yim rau rov zoo, txhim kho cov neeg mob kev paub txog kev kho mob.
Rau kev tiv thaiv tsis zoo, cov chaw tsim khoom cov khoom lag luam kuj muaj qhov ua tau zoo tshaj plaws hauv kev zam kom tsis txhob muaj kab mob cauda equina paj hlwb. Cov qauv anatomical ntawm cauda equina paj hlwb yog complex, tsim los ntawm ntau pawg ntawm cov paj hlwb, thiab txuas nrog tus txha caj qaum ntawm L1 conus medullaris. The nerve roots are densely distributed and fragile, and improper puncture operation or unqualified instrument tip is easy to cause nerve compression and stabbing injury, resulting in severe sequelae such as limb numbness and motor dysfunction. Lub atraumatic mem hluav point spinal needle uas tsim los ntawm cov tuam txhab lag luam niaj hnub muaj cov tswv yim tsim thiab kev hloov pauv, uas tuaj yeem nkag mus rau qhov chaw txha caj qaum raws qhov sib txawv ntawm lub cev, zam kev sib cuag thiab extrusion nrog cov paj hlwb, thiab tiv thaiv cauda equina paj hlwb raug mob.
Ntxiv nrog rau qhov zoo ntawm kev nyab xeeb, cov chaw tsim khoom- cov khoom lag luam kuj tseem muaj txiaj ntsig zoo rau kev kho mob. Cov txheej txheem tshwj xeeb xim xim txheej txheem pab cov neeg ua haujlwm kho mob txhim kho kev ua haujlwm zoo thiab txo qis kev pheej hmoo ua haujlwm tsis raug; lub siab -precision integrated koob lub cev ua kom ruaj khov puncture thiab txhim kho qhov kev vam meej ntawm ib qho - sij hawm puncture; customizable ntev thiab specifications ua tau raws li qhov xav tau ntawm cov pab pawg tshwj xeeb thiab kev ua haujlwm nyuaj. Thaum tiv thaiv cov teeb meem, cov khoom lag luam txhim kho tag nrho cov txiaj ntsig ntawm kev kuaj mob thiab kev kho mob, txo cov kev mob ntshav qab zib thiab cov nqi kho mob ntxiv, thiab yog ib qho tseem ceeb ntawm - cov cuab yeej kho mob tseem ceeb rau kev ua haujlwm ntawm tus txha nqaj qaum niaj hnub.
