Phau ntawv ceev rau cov ntsiab lus tseem ceeb

• Gauge (G tus nqi):Qhov loj dua tus naj npawb, qhov zoo ntawm rab koob. Cov thyroid FNA feem ntau siv 22–25G; Lub plab zom mov ntawm lub cev nqaij daim tawv nqaij / PTC feem ntau siv 20–22G; Qee lub sij hawm 18G yog siv rau thawj zaug puncture ntawm cov kua dej loj. Nco ntsoov tias cov chaw tsim khoom sib txawv yuav muaj qhov sib txawv me ntsis OD ntawm tib tus nqi G; ib txwm txheeb xyuas tus nqi mm (piv txwv li, 22G ≈ 0.7 mm OD, 21G ≈ 0.8 mm, 20G ≈ 0.9 mm).
• Siv Length:Ntev ntev yog 9 cm / 15 cm / 20 cm. Superficial (thyroid, mis) xaiv 9 cm; daim siab / raum xaiv 15 cm; Cov neeg mob rog lossis cov kab mob sib sib zog nqus retroperitoneal yuav xav tau 20 cm lossis ntev dua.
• Bevel Lub kaum sab xis:Standard Chiba koob muaj 25℃bevel; qee cov tuam ntxhab muab 30℃lossis adjustable kaum sab xis. Cov ces kaum me me muaj qhov ua haujlwm siab dua me ntsis tab sis yooj yim rau kev tswj cov kev taw qhia; cov ces kaum loj nkag tau yooj yim dua tab sis nws yooj yim rau deviation.
• Echo-tip/Marker Ring:​ Laser-etched lossis sonolucent rings nyob ze ntawm rab koob txhim kho ultrasound pom. Pom zoo rau niaj hnub stocking rau US -cov txheej txheem qhia.

Hom thiab kev xaiv hauv tsev

Cov khoom lag luam thoob ntiaj teb (xws li Cook, BD, Hakko) muaj lub koob npe nrov rau kev sib tsoo zoo sib xws, txheej lubrication, thiab ntim khoom yooj yim, tab sis ntawm cov nqi siab dua. Cov tuam txhab ua raws cai hauv tsev (ISO 13485 + daim ntawv pov thawj NMPA) tuaj yeem ua tau raws li qhov xav tau ntawm kev kho mob hauv cov xwm txheej niaj hnub FNA/PTC.

Cov lus qhia kom zoo tshaj tus nqi

Txhawb nqa cov txheej txheem coaxial puncture: Tsim ib qho chaw nrog ib rab koob Chiba, tom qab ntawd muab cov hlua khi. Ntau qhov piv txwv lossis kev txhaj tshuaj tuaj yeem ua tau yam tsis tau hloov lub koob, txo cov nqi siv rau ib kis;

Tshuag specifications raws li cov txheej txheem kom tsis txhob "overkill" (piv txwv li, tsis txhob Tshuag 18G rau cov txheej txheem thyroid);

Sib tham txog kev cog lus txhua xyoo nrog cov neeg muag khoom + cov khoom tsis raug xa rov qab / pauv cov nqe lus. Ua tib zoo saib seb daim ntawv pov thawj kev sau npe ntawm daim ntawv thov them rau cov txheej txheem phiaj xwm (FNA/drainage/PTC).

Lub hauv paus ntsiab lus xaiv qhov kawg yog: kev siv tshuaj kho mob ua ntej, kev ua raws cai tsis yog- sib tham tau, thiab tus nqi qis tshaj plaws (nrog rau cov nqi zais ntawm cov teeb meem).
