Specifications ntawm alub mis biopsy koobyog thawj tus txheej txheem tswj cov txheej txheem txheej txheem thiab cov qauv zoo. Ob lub ntsiab parameter yogKoob LengththiabNtsuas (inch). Kev lag luam daim ntawv cog lus hais tiasntau dua gauge tooj sib raug rau finer diameters, ua rau muaj kev raug mob punctures tsawg. Conversely, koob ntev yuav tsum phim qhov tob tob. Kev sib raug zoo ntawm cov kev txwv no sib npaug me ntsis cuam tshuam kev nyab xeeb nrog cov qauv kev ncaj ncees, ua haujlwm raws li tus kws kho mob thawj qhov kev siv rau ua ntej - kev xaiv cov cuab yeej siv thiab cov txheej txheem txheem.

Gauge Selection rau Clinical Practice:

Mainstream mis biopsy koob muaj xws li los ntawm9g18 ua, sib xws rau cov txheej txheem sib txawv thiab hom kab mob.

9G & 11G (loj bore):Feem ntau siv hauvNqus -Assisted Breast Biopsy (VABB). Lub lumen loj dua tso cai rau kev nrhiav tau ntawm cov ntaub so ntswg cylindrical cores nrog khaws cia architecture, txhawb kev sib txawv ntawm benign hyperplasia,hauv qhovcarcinoma, thiab mob qog noj ntshav. Cov ntsuas no zoo tagnrho rau microcalcifications, occult nodules, thiab kuaj mob nyuaj. Cov qauv ntim siab txo qhov xav tau rau ntau qhov kev hla, txo cov neeg mob tsis xis nyob thiab cov ntaub so ntswg raug mob - ua rau lawv tus qauv rau kev kuaj pom tseeb thiab txo qis qis ntawm cov kab mob benign.

14G & 18G (Me me-rau- Nruab Nrab Nruab Nrab):Tus qauv rauCore Needle Biopsy (CNB)thiab feem ntau siv tshuaj ntsuas ntsuas.

• 14G:​ Balances sample yield with minimal invasion. Suitable for palpable masses >1cm thiab BI-RADS 4 qhov chaw tsis txaus ntseeg, muab cov ntaub so ntswg txaus rau niaj hnub histopathology thiab molecular subtyping.
• 18G:Tsawg heev, feem ntau yog siv rau Fine Needle Aspiration Biopsy (FNAB) lossis cystic fluid aspiration. Zoo tagnrho rau cov me me nodules thiab cysts. Cov txheej txheem yog nrawm nrog kev rov qab sai, tab sis cov qauv muaj cov khoom siv cytological nkaus xwb, tsis muaj cov ntaub so ntswg. Nws ua haujlwm raws li cov cuab yeej tshuaj ntsuam xyuas ua ntej es tsis yog cov cuab yeej kuaj mob kom paub tseeb rau cov kab mob malignancies.
• Length Selection: The "Lesion Depth Adaptation Principple":

Muaj qhov ntev li ntawm5 cm rau 15 cm, haum rau ntau tus neeg mob morphologies thiab qhov chaw lesion.

• 5-8 cm (luv luv):Rau cov neeg mob uas muaj cov ntaub so ntswg loj ntawm lub mis thiab qhov txhab tawv nqaij. Muab txoj hauv kev luv luv, ua kom yooj yim zam kom tsis txhob muaj cov hlab ntsha sib sib zog nqus thiab lymphatics.
• 10-12 cm (Standard):​ Cov neeg ua haujlwm kho mob, haum rau nruab nrab -glandular lesions nyob rau hauv feem ntau ntawm cov neeg mob.
• 12-15 cm (ntev):​ Tshwj xeeb yog tsim los rau cov neeg mob rog rog lossis sib sib zog nqus- zaum qhov txhab. Ua kom muaj kev hla dhau los ntawm cov txheej adipose tuab kom ncav cuag lub hom phiaj, tiv thaiv kev ua tsis tiav vim qhov tsis txaus koob.
• Common Pitfalls:​ Cov kev kho mob yuam kev feem ntau tshwm sim los ntawm cov kev qhia tsis sib haum - siv lub ntsuas ntsuas zoo rau cov kab mob loj yuav ua rau tsis muaj qhov piv txwv thiab qhov tsis zoo; siv ib rab koob luv rau qhov mob sib sib zog nqus ua rau lub hom phiaj ua tsis tiav. Cov kws kho mob yuav tsum xaiv cov kev qhia tshwj xeeb raws li qhov loj me, qhov tob, thiab cov duab kos duab. Standardized matching maximizes puncture raug, xyuas kom meej kuaj validity, thiab muab ib tug txhim khu kev qha lub hauv paus rau kev tswj kab mob ntawm lub mis.
