Comprehensive Analysis Ntawm Chiba Koob

Qhov Zoo Tshaj Plaws Zoo Tshaj -Needle Aspiration Biopsy Instrument hauv Interventional Radiology

https://radiopaedia.org/articles/chiba-needle

Nrog kev nce ntau ntawm cov duab- coj kev kuaj mob thiab kev kho mob tsawg kawg nkaus,Koob(tseem hu ua Chiba biopsy koob lossis Chiba aspiration needle) tau dhau los ua ib qho ntawm cov khoom siv zoo tshaj plaws -Kub puncture instruments hauv cov chaw ua haujlwm, chaw ua haujlwm ultrasound, thiab chaw kuaj hluav taws xob thoob ntiaj teb. Raws li nyias-walled, hollow, ultra- koob zoo aspiration, nws yog Ameslikas tsim thiab muaj npe los ntawm Chiba University hauv Nyij Pooj, tsim tshwj xeeb rau cov duab- coj (ultrasound lossis CT) Fine Needle Aspiration (FNA) cytological biopsy. Nws kuj yog siv dav rau cyst lossis abscess aspiration thiab kua, Percutaneous Transhepatic Cholangiography (PTC), vascular nkag mus, thiab ntau yam duab -cov txheej txheem kev cuam tshuam.

Los ntawm cov chaw tsim khoom qhov kev xav, tus qauv Chiba koob feem ntau muaj cov cannula (kab koob), stylet (obturator), hub (Luer Lock hub), thiab qhov tob nres. Lub cannula feem ntau yog ua los ntawm kev kho mob -qib SUS304 lossis SUS316L stainless hlau, muab biocompatibility zoo heev, corrosion kuj, thiab txaus rigidity. Qee cov qauv siab -kawg qauv feature sandblasted los yog micro-cov lus qhia rau kev txhim kho ultrasound tip echogenicity (Echo Tip), ua kom yooj yim tiag tiag - lub sij hawm koob tshuaj tiv thaiv hauv qab duab. Lub hub feem ntau yog ua los ntawm kev kho mob- qib ABS, PC, lossis PP yas, nrog cov xim coding los ntawm ntsuas (G) kom paub ceev ceev los ntawm tus neeg teb xov tooj.

Hom Chiba koob specifications muaj li ntawm 18G mus rau 23G (feem ntau 20G, 21G, 22G), sib xws rau sab nraud ntawm kwv yees li 0.7 hli-1.2 hli. Standard ntev yog 9 cm, 15 cm, thiab 20 cm (kwv yees . 3.5"–8"), nrog rau kev cai ntev txog li 25 cm los yog 30 cm muaj nyob rau hauv kev thov. Lub koob taub feem ntau yog tsim los nrog luv bevel (bevel kaum sab xis 25℃-30 degree) lossis hloov kho Quincke bevel. Ua ke nrog cov phab ntsa ultra- nyias nyias, qhov no txo ​​qis qhov kev tiv thaiv, txo cov kua muag ntawm lub cev, thiab ua kom muaj cov qauv cellular txaus nyob rau hauv qhov kev xav tsis zoo.

Tsis zoo li kev txiav cov koob txhaj tshuaj (xws li Tru-Txiav lossis Franseen koob), Chiba koob yog qhov kev xav tau- hom koob zoo tsim feem ntau kom tau txais cov qauv cytological ntau dua li cov ntaub so ntswg loj. Yog li nws yog qhov hloov tsis tau rau qhov kev tshuaj ntsuam thawj zaug thiab kuaj mob ntawm cov thyroid micronodules, focal daim siab mob, pancreatic masses, cov qog ntshav qog ntshav, thiab cov qog mis me me. Cov neeg tsim khoom yuav tsum tau them nyiaj tshwj xeeb rau cannula concentricity, sab hauv phab ntsa smoothness, thiab tip edge sharpness - peb yam no ncaj qha txiav txim siab puncture, tus neeg mob theem, thiab cov qauv txaus.

Nws yog ib qho tsim nyog sau cia tias niaj hnub Chiba koob manufacturers tau hloov zuj zus los ntawm cov qauv siv tau rov qab mus rau ib zaug - siv cov ntim tsis muaj menyuam (EO - Ethylene Oxide sterilized) kom tau raws li cov cai tswj kev kis kab mob hauv tsev kho mob. Cov koob pov tseg Chiba feem ntau muaj cov cim qhov tob (ib cm lossis 5 hli), zawv zawg qhov tob nres, kaw pob tshab hubs, thiab rau cov khoom xa tawm mus rau Tebchaws Europe thiab Asmeskas, yuav tsum dais CE Marking thiab tsim nyob rau hauv ISO 13485 certified system.

Rau Chiba koob manufacturers, core competitiveness nyob rau hauv: ① precision drawing thiab sizing ntawm ultra-nyias-walled stainless hlau tubing; ② micron- qib kev sib tsoo thiab polishing; ③ xaiv tau ultrasonic ncha marker ua; ④ Kev ntim cov khoom tsis muaj menyuam, cov khoom seem, thiab cov khoom xau. Raws li cov txheej txheem cuam tshuam tsawg kawg nkaus txuas mus rau cov tsev kho mob thawj zaug, Chiba koob - raws li "paj siab siab- ntim" cuam tshuam cov khoom siv tau zoo - txaus siab rau kev lag luam tsis tu ncua thiab yog cov khoom lag luam txuas nrog tus nqi- ua haujlwm zoo nrog cov khoom xa tuaj ntim hauv cov khoom siv khoom siv.
