https://radiopaedia.org/articles/chiba-needle
Feem ntau siv cov koob txhaj tshuaj tuaj yeem muab faib ua peb pawg los ntawm kev ua haujlwm zoo: rab koob zoo aspiration (Chiba / Turner bevel koob), txiav koob (Tru-Txiav sab-} koob) thiab coaxial / interventional kua koob (trocar tip lossis pointed flat tip). To taub lub uniqueness ntawm lubSiv rab koobcov lus qhia pab hauv kev xaiv rational.

Tshwj xeeb zoo ntawm Chiba koob Tip
Flexibility: 21G-23G Chiba koob muaj cov phab ntsa nyias, tso cai rau me ntsis elastic khoov thaum hla ntawm ntug sab sauv ntawm tav los yog 微调 kev taw qhia raws txoj kev nkhaus - muaj peev xwm粗 txiav koob tsis muaj.
Tsawg invasiveness: Fine tip + me me txheej txheej ua rau muaj kev puas tsuaj rau cov hlab ntsha thiab cov kua tsib ducts, haum rau kev khiav hauj lwm nyob ib ncig ntawm cov txheej txheem tseem ceeb (xws li, thawj zaug PTCD puncture, portal vein puncture).
Versatility: Ib rab koob Chiba tuaj yeem ua cytological biopsy, sib piv txhaj tshuaj (cholangiography/lymphangiography), tshuaj txhaj tshuaj (PEI ethanol txhaj rau me me hepatocellular carcinoma), thiab cov lus qhia qhia.
Kev txwv thiab Complementarity
Chiba koob taub tsis tuaj yeem tau txais cov kab mob histological txaus rau immunohistochemistry lossis genotyping. Rau cov khoom loj dua lossis sib npaug li 1.5 cm, yuav tsum muaj 18G txiav rab koob biopsy. Feem ntau, rab koob Chiba yog siv thawj zaug rau hauv zos los yog tsim kom muaj ib coaxial channel, tom qab ntawd tus Tru-Txiav rab koob tau muab tso rau qhov piv txwv - ob qho ntxiv es tsis yog hloov ib leeg hauv kev kho mob.
Nyob rau hauv luv luv, Chiba rab koob embodies tus tsim lub tswv yim ntawm "nyias, ntse, saj zawg zog, thiab patent," ua rau nws yog ib qho tseem ceeb ntawm lub minimally invasive interventional diagnostic system.
