ZooKoobAspiration Biopsy (FNAB) yog lub hauv paus thiab cov txheej txheem tseem ceeb hauv kev kuaj mob tsawg kawg nkaus rau cov kab mob ntawm lub mis. Kev siv lub hauv paus ntsiab lus tsis zoo ntawm lub siab xav ntawm ultra- koob tshuaj biopsy zoo, FNAB tau txais cov qauv dawb-floating hlwb los ntawm qhov mob ntawm lub mis los pab txhawm rau kuaj cytopathological. Nws ua hauj lwm raws li ib qho tseem ceeb minimally invasive modality rau thawj zaug kuaj lub mis kuaj, lesion characterization, thiab ua ntej sib txawv ntawm benign thiab malignant pathologies. Qhov txawv ntawm cov ntaub so ntswg-txoj kev biopsy tseem ceeb xws li Core Needle Biopsy (CNB) lossis Nqus Tsev-Assisted Biopsy (VAB), lub cim ntawm kev mob ntshav siab nyob rau hauv nws lub xov tooj ntawm tes- qib sampling, tsis muaj cov ntaub so ntswg- kev cuam tshuam tseem ceeb, thiab ultra- qhov txhab tsim tsawg. Lub hauv paus tseem ceeb ua kom siv thev naus laus zis no yog tus qauv kev kho mob - qib koob tshuaj ntawm lub mis aspiration biopsy.
Los ntawm kev faib cov cuab yeej kho mob standpoint, lub mis aspiration biopsy koob yog categorized raws li ib tug pov tseg interventional puncture consumable. Nws yog engineered tshwj xeeb rau transcutaneous sampling ntawm mos mos cov ntaub so ntswg, haum rau lub anatomical nuances ntawm lub mammary caj pas, nrog rau nws cov xoob stromal sib xws, nplua nuj vascularity, thiab qhov sib txawv qhov tob ntawm cov kab mob pathological. Nws cov txheej txheem kev ua haujlwm tseem ceeb suav nrog: nce qib 22G–25G ultra- rab koob zoo los ntawm daim tawv nqaij thiab mammary parenchyma kom ncav cuag lub hom phiaj lesion; txuas lub syringe sab nraud los ua kom muaj kev ruaj ntseg tsis zoo; siv lub zog nqus dej no kom tshem tawm thiab nqus cov hlwb dawb thiab cov kua dej sib txuas los ntawm qhov txhab; thiab thaum kawg, hloov cov qauv mus rau cov swb rau kev kho, staining, thiab cytological tsom xam. Tseem ceeb heev, cov txheej txheem refrains los ntawm excising loj cov ntaub so ntswg fragments, li no maximizing lub preservation ntawm lub mis architecture.
Lub chaw kho mob adaptability ntawm aspiration biopsy koob yog profoundly reflected nyob rau hauv nws standardized dimensional tsim. Kev lag luam- tus qauv specifications ncua sij hawm los ntawm 22G mus rau 25G, sib xws rau txheej diameters (OD) ntawm 0.5 mm–0.7 mm, nrog puab diameters (ID) tswj ntawm lub micrometer scale. Qhov no optimizes ob qho tib si insertion fluency thiab cellular aspiration efficiency. Ncej ntev yog muaj ntau haiv neeg kom haum raws li qhov kev kho mob sib txawv: cov palpable loj loj, tob- zaum occult lesions, thiab cov qog ntshav hauv axillary. Cov qauv luv luv haum rau cov kab mob ntawm lub mis, thaum lub shafts ntev ua tau raws li qhov xav tau ntawm kev sib sib zog nqus-cov ntaub so ntswg sampling, ua tiav npog cov ntaub ntawv kho mob niaj hnub.
Kev xaiv cov khoom siv yog linchpin txiav txim siab txog kev nyab xeeb thiab kev ruaj ntseg ntawm cov koob no, nrog peb tus thawj tswj hwm kev kho mob - qib cov khoom siv tswj kev siv tshuaj kho mob. Qhov thib ib yog kev kho mob stainless hlau (tshwj xeeb yog qib 304 thiab 316L). Ua kev zoo siab rau qhov tshwj xeeb corrosion kuj, cov qauv kev ruaj ntseg, thiab biocompatibility, nws tseem yog cov khoom siv tshaj plaws. Nws rigidity minimizes dabtsi yog khoov thaum repetitive punctures, ua rau nws haum rau cov pa reusable koob. Qib thib ob yog titanium alloy. Lub teeb thiab hloov tau yooj yim dua li cov hlau tsis muaj steel, nrog kev ua haujlwm zoo dua qub, titanium koob txo tus neeg teb xov tooj tes qaug zog thiab tshee, ua pov thawj zoo hauv siab -precision sib sib zog nqus biopsies. Qhov thib peb suav nrog kev kho mob- qib polymer plastics, feem ntau yog siv hauv cov hubs pov tseg thiab cov qauv sib txuas. Muab hluav taws xob rwb thaiv tsev, ruaj khov tsis muaj menyuam, thiab tus nqi-kev ua tau zoo, cov polymers no ua raws li ib qho - siv cov qauv.
Raws li cov cuab yeej tseem ceeb rau kev kuaj mob tsawg kawg nkaus ntawm lub mis, lub koob tshuaj aspiration biopsy muab cov txiaj ntsig tseem ceeb thoob plaws peb qhov ntev: kev raug mob tsawg, kev nyab xeeb siab, thiab kev hloov pauv sai. Piv nrog rau lwm txoj kev siv tshuab biopsy, FNAB khav theeb ncaj qha cov txheej txheem kev thauj mus los, feem ntau obviating qhov xav tau rau cov duab taw qhia nyuaj, thiab lub sijhawm luv luv heev. Cov neeg mob tsis xis nyob yog qhov tsawg, tsis muaj caws pliav, thiab cov teeb meem tsis txaus ntseeg. Nyob rau hauv niaj hnub kev saib xyuas lub mis txuas ntxiv, FNAB, txhawb nqa los ntawm cov yam ntxwv tseem ceeb ntawm nws cov koob mob siab rau, tuav lub luag haujlwm tseem ceeb hauv kev kuaj thawj zaug. Nws sawv raws li qhov kev daws teeb meem tsawg tsawg tshaj plaws rau thawj cov tsev kho mob, kev kuaj mob niaj hnub, thiab qhov ua tau sai ntawm cov kab mob tsis txaus ntseeg, muab kev txhawb nqa tseem ceeb rau kev kuaj pom ntxov, kuaj mob, thiab cuam tshuam cov kab mob ntawm lub mis.
