Raws li kev yees duab - sib xws zoo koob, lubSiv rab koobtuaj yeem siv tau nyob rau hauv yuav luag txhua hom kev taw qhia cov duab tseem ceeb, tab sis cov kev taw qhia sib txawv muaj qhov sib txawv ntawm qhov tseeb, tiag - lub sijhawm muaj peev xwm, hluav taws xob raug, thiab tus nqi. Kev xaiv tsim nyog muaj feem cuam tshuam ncaj qha rau qhov ua tau zoo ntawm kev sib tsoo thiab kev nyab xeeb.

1. Ultrasound (Tebchaws Asmeskas)-Guided Chiba Needle Biopsy

Qhov zoo: Tiag - lub sij hawm dynamic zaub ntawm tag nrho cov txheej txheem kev txhaj tshuaj (muaj zog ncha ntawm rab koob thiab lub taub hau, kho qhov kev sojntsuam nrhiav), tsis muaj ionizing hluav taws xob, tuaj yeem ua tau ntawm lub txaj, tus nqi qis, kev daws teeb meem zoo ntawm cystic- cov khoom loj, xim Doppler tuaj yeem zam cov hlab ntsha, tshwj xeeb tshaj yog rau cov qog nqaij hlav hauv lub raum, cov qog nqaij hlav, cov qog nqaij hlav thiab lub raum. lub cev. Qhov tsis zoo: Kev nkag mus tsis zoo ntawm cov pa roj- muaj cov ntaub so ntswg ( ntsws, gastrointestinal gas- puv loops); txwv tsis pub muaj qhov sib sib zog nqus me me los yog cov kab mob tom qab cov pob txha; tus neeg teb xov tooj kev paub yuav tsum paub txog rab koob anisotropy artifacts; Cov duab zoo txo ​​qis hauv kev rog lossis plab hnyuv cuam tshuam. Kev pom zoo: Cov thyroid / mis / lymph nodes yog ua tau zoo tshaj plaws nyob rau hauv US kev taw qhia; daim siab / raum / pancreas kuj tuaj yeem ua tau nyob rau hauv Teb Chaws Asmeskas yog tias qhov txhab pom meej meej.

2. CT-Guided Chiba Needle Biopsy

Qhov zoo: Cov kev daws teeb meem siab heev, qhov chaw nyob ntawm qhov tob, me me (txawm tias<1 cm), or lesions adjacent to bony structures or obscured by lung tissue (such as peripheral pulmonary nodules, mediastinal lesions, retroperitoneal, pelvic masses); multi-planar reconstruction (MPR) can plan the optimal needle path to avoid blood vessels and bones; good penetration of lung gas tissue (first choice for lung biopsy). Disadvantages: Not real-time (requires step-by-step scans to confirm needle tip position), patients are exposed to X-ray radiation, operation takes longer, cost is higher than US, cannot directly display the entire needle tract in real time. Recommendation: Pulmonary nodules, deep retroperitoneal/pelvic lesions, lesions adjacent to bones, and those not clearly visible on US should be done under CT guidance.

3. Fluoroscopy (C-arm) thiab MRI Kev taw qhia

Fluoroscopy yog qhov yooj yim thiab ceev, haum rau cov kab mob ntsws loj / pob txha pom nyob rau hauv fluoroscopy, tab sis tsis zoo rau qhov mob me me, maj mam hloov los ntawm CT. MRI tsis muaj hluav taws xob thiab tuaj yeem siv tau rau cov neeg mob uas muaj kev txwv tshwj xeeb rau hluav taws xob lossis cov chaw tshwj xeeb (mis, prostate, qaum qaum), tab sis yuav tsum muaj kev mob siab rau tsis yog -Magnetic Chiba koob (titanium alloy / tsis yog- cov hlau tsis sib nqus), nrog rau cov nqi siab dua thiab txwv tsis pub muaj npe.

4. Chiba koob Specification xaiv cov lus pom zoo

• Gauge (sab nraud txoj kab uas hla):​ Feem ntau 21G (OD≈0.8 mm) thiab 22G (OD≈0.7 mm), ntsuas cell sampling ntim thiab raug mob; 20G yog me ntsis thicker rau cov ntaub so ntswg nyuaj tab sis me ntsis nce los ntshav txaus; 23G yog qhov zoo dua rau cov cheeb tsam vascular lossis menyuam yaus. Txiav biopsy yuav tsum tau 14-18G tuab koob, uas tsis yog nyob rau hauv Chiba koob.
• Ntev:15 cm yog tsim rau superficial / siab / thyroid; 20 cm yog siv rau tob ntsws / retroperitoneal / raum; 30 cm yog qee zaus siv rau cov neeg mob rog rog lossis cov haujlwm sib sib zog nqus tshwj xeeb.
• Koob tip bevel:Standard 25℃-30℃bevel yog qhov zoo rau kev nkag mus thiab kev ua haujlwm zoo; qee lub tuam txhab muab ultra- ntse bevels.
• Khoom siv:304/316L stainless hlau yog lub ntsiab xaiv, nrog electropolished nto los txo kev sib txhuam; MRI kev taw qhia yuav tsum tsis yog - sib nqus titanium lossis cov alloys tshwj xeeb.
• Ntim:​ Sterile ib zaug lossis ob lub hlwv pob, qee qhov uas tshem tau cov stylets lossis ua ntej - txuas Luer lock connectors kom yooj yim syringe txuas.

Cov lus pom zoo: Rau cov khoom siv hauv nruab nrog cev thiab cov khoom loj uas tuaj yeem pom hauv lub sijhawm, ua ntej US + 21G/22G Chiba koob; rau pulmonary nodules thiab tob pom qhov tsis zoo, siv CT + 22G Chiba koob; 21G lossis 22G Chiba koob feem ntau yog siv rau thawj zaug PTC / PTCD puncture. Kev ua kom raug raws li kev taw qhia txoj kev thiab rab koob tshwj xeeb yog lub hauv paus rau kev txhim kho qhov zoo thiab txo cov teeb meem.
