Los ntawm Roholm & Iversen mus rau Menghini

Lub siab biopsy tseem yog tus qauv kub rau kev kuaj mob siab- qhov tseeb tsis hloov pauv txij li Roholm thiab Iversen thawj zaug tshaj tawm lub siab ua rau lub siab nyob rau xyoo 1939. Tab sis cov lus nug ntawm "qhov twg koob yuav siv" ib txwm npog qhov sib faib sab hauv:Aspiration School( sawv cev los ntawmMenghini,1958) vsTxiav Tsev Kawm Ntawv​ (sawv cev los ntawm Tru-Txiav, 1960s caij nplooj ntoos hlav-loaded). Rau cov neeg sab nrauv, nws zoo li "laus tsim vs. tsim tshiab"; Rau cov neeg sab hauv, nws yog kev faib ua haujlwm raws li ob qho kev xav tau ntawm pathological. Yog vim li cas Menghini koob-yug xyoo 1958- tseem tuav ib qho chaw hauv Western OEM catalogs hnub no tsis yog kev xav; nws yog qhov kev ntshaw- qauv qauv ua tiav qee qhov xwm txheej kho mob Tru-Cut tsuas yog hloov tsis tau.

1939–1958: Lub Embryo of Negative-Kev Siab Siab

Roholm & Iversen pib siv lub "loj- rab koob + phau ntawv suction"- nyob ib ncig ntawm 17G, kos daim siab rau hauv rab koob lumen nrog lub tshuab nqus tsev vacuum ua ntej severing nws. Cov qauv no yog fragmented strips sib xyaw nrog cov hlwb. Qhov kom zoo dua: ceev thiab muaj peev xwm siv tau ib txoj kab uas hla sab nraud (16-18G txaus). Qhov tsis zoo: tus qauv yog "fragmented," ua rau nws tsis tshua zoo rau cov kab mob uas xav tau kev pom ntawm cov kab mob siab hepatic lobule.

Nyob rau hauv 1958, Italian pathologist Giorgio Menghini systematized cov txheej txheem: txhais qhov haum ntawm ib tug txheej txheem cannula thiab puab stylet, standardizing lub siab tsis zoo tus nqi (feem ntau yog ib tug 20-30 mL syringe rub mus rau 10-15 mL ntawm lub tshuab nqus tsev), thiab tsim ib tug "ib qho kev ntxig", kev ua haujlwm tsis tu ncua. Qhov no tau dhau los ua lub cev pob txha ntawm rab koob Menghini- tsis hloov pauv mus rau hnub no.

Vim li cas Tru-Txiav Tsis Tau Hloov Tag Nrho Menghini

Tru-Txiav (tom qab hloov mus rau hauv cov khoom siv xws li Bard Magnum thiab Manan caij nplooj ntoos hlav-loaded systems) ua haujlwm ntawm "trocar- nyob rau hauv -cannula" txoj cai-thaum raug tua, sab hauv trocar nce qib ua ntej rau thauj cov ntaub so ntswg, tom qab ntawd sab nrauv cannula hlais cov ntaub so ntswg. 1.5-2 cm ntev. Qhov no yog qhov zoo tshaj plaws rau daim siab fibrosis staging thiab qog architecture ntsuam xyuas. Suab zoo li tus yeej meej? Tseem Menghini yeej nyob hauv peb qhov xwm txheej tshwj xeeb:

• Cov neeg mob nrog borderline coagulation:Menghini tuaj yeem tsim tawm ntawm 16-18G; Tru-Txiav caij nplooj ntoos hlav- cov khoom siv thauj khoom feem ntau pib ntawm 14–16G. Cov caliber me me=qis los ntshav txaus.
• Fatty daim siab / cirrhotic ntaub so ntswg zoo nkauj:Aspiration yog paradoxically ntau npaum li cas ntawm retrieving "mos + fragmented" cov ntaub so ntswg -Tru- Txiav nquag rov qab "cov hlab ntsha" nyob rau hauv lub siab fatty siab.
• Ua ke cytology + histology:Thaum cov lymphoma lossis leukemic daim siab infiltration yog xav tias, cov khoom aspirated rau smear cytology yog rhiab tshaj li core biopsy ib leeg; Menghini ib txwm xa ob qho tib si.

Daim ntawv niaj hnub ntawm Menghini

Tus thawj Menghini yog peb daim qauv tsim: hub + koob raj + puab stylet + syringe connector. Niaj hnub no lub ntsiab lus 改良 (hloov) versions feature lub luer - xauv lub tshuab nqus tsev txuas, tso cai rau ib leeg -kev ua haujlwm (tus thawj feem ntau xav tau tus pab rub lub koob txhaj). Rau OEMs xws li Manners Technology, 90% ntawm Menghini xaj yog ob qhov tshwj xeeb: 16G / 18G × 150-200 mm, nrog 20℃-25℃bevel kaum sab xis thiab "flat-head micro-convex" stylet tip uas kaw cov koob bevel kom tsis txhob nkag mus rau hauv cov ntaub so ntswg. Cov no yog cov txheej txheem kho dua tshiab nyob rau saum xyoo 1958 thawj- lub cev pob txha.

📌 Kev Paub Txog Kev Muag Khoom:Tsis txhob tso tseg Menghini li "tawm xyoo 1958 tsim." Tam sim no Western pathology department paradigm yog "Tru-Txiav rau niaj hnub, Menghini tshwj tseg rau 10-15% tshwj xeeb." Kev txiav txim rau Menghini tau loj hlob qeeb hauv peb lub niches: cov chaw ua rau lub siab rog, kev sib tham txog hematology rau kev koom tes nrog daim siab, thiab cov menyuam yaus lub siab biopsies (Tru-Txiav kev tawm tsam hauv qab 16G).
