Txawm hais tias lub hauv paus ntsiab lus ntawm PTC koob (Chiba hom) yog kev sib koom ua ke, cov chaw tsim khoom muaj ntau yam - kev qhia tshwj xeeb ua ke kom ua tau raws li cov neeg mob sib txawv ntawm lub cev, cov kab mob biliary, thiab cov neeg siv khoom nyiam. Kev taw qhia txog kev xaiv kev tshawb fawb pab cov neeg faib khoom thiab xaus - cov neeg siv khoom kom raug, txo cov kev kho mob ua tsis tiav los ntawm cov kev qhia tsis sib xws.

Gauge (Outer Diameter) Xaiv:

• 22G (OD ≈ 0.7 mm, ID ≈ 0.41 mm):​ Feem ntau yog siv rau PTC diagnostic cholangiography thiab PTCD ua ntej -pass, ntsuas qhov cuam tshuam tsawg kawg nkaus nrog cov lus qhia (ua raws li 0.018 "micro-guidewire). Pom zoo raws li tus qauv configuration.
• 21G (OD ≈ 0.8 hli):me ntsis loj dua lumen, haum rau lub siab fibrotic loj los yog thaum xav tau kev txhawb zog; tseem siv tau rau thawj zaug - dhau los ntawm kev sib pauv.
• 20G (OD ≈ 0.9 hli):​ Qee lub chaw siv ncaj qha rau ib qho - kauj ruam PTCD (nrog rau micro- tus qhia), tab sis kev raug mob tau nce ntxiv.
• 23G (OD ≈ 0.6 hli):​ Ultra-zoo, haum rau cov menyuam yaus, cov neeg laus uas tsis muaj zog, lossis PTC ntshiab tsis muaj catheter tso; Nco ntsoov lub lumen me me yuav tsum tau ceev faj ntxiv nrog cov kab lus qhia.
• Ntev Xaiv:150 mm (superficial / left lobe subxiphoid approach), 200 mm (standard adult right mid-axillary approach), 250–300 mm (cov neeg mob rog rog los yog tob tob tob tob tob tob). Cov neeg tsim khoom feem ntau Tshuag 150/200 hli raws li tus qauv, nrog rau qhov ntev ntev muaj nyob ntawm qhov xav tau.

Khoom siv thiab kev ua tau zoo sib txawv:

• SUS304:Tus nqi qis, lub zog zoo, txaus siab rau feem ntau cov kev xav tau.
• SUS 316L:Superior corrosion kuj, zoo dua rau cov dej sib cuag ntev; xaiv rau high - kab kawg.
• NiTi (Nitinol) ncej los yog tag nrho koob:​ Superelastic thiab kink-resistant, tsis tshua muaj deformation nyob rau hauv nkhaus daim siab parenchyma, haum rau complex multi- kho punctures, tab sis ntawm tus nqi siab dua.

Functional Add-ons:

• Ultrasound visibility markers (ntsis roughening / micro-pitting / kauv etching):Kev pom zoo zoo raws li tus qauv txhawm rau txhim kho cov lus qhia zoo hauv qab kev taw qhia ultrasound.
• Xim -coded gauge rings:Ua kom ceev cov kev qhia tshwj xeeb, txo qis kev tsis sib haum xeeb.
• Cov qhab nia kawm tiav (txhua 1 cm):Scale markings nyob rau hauv 5-10 cm los ntawm lub ntsis pab nyob rau hauv judging insertion qhov tob.
• Hydrophilic txheej (sab hauv lumen lossis sab nrauv):Qee qhov hwm versions muaj cov txheej txheem sab hauv hydrophilic kom txo tau cov kev sib txhuam ntawm kev sib txhuam; sab nrauv hydrophilic txheej txo cov ntaub so ntswg tsis kam.

Cov lus pom zoo ntawm cov neeg tsim khoom Configuration:

Lub Tsev Haujlwm Saib Xyuas Tsev Kawm Ntawv Qib Siab / Kev Qhia Tsev Kho Mob:22G × 200 mm (nrog pom kev cim + cim), 21G × 200 mm nyob rau hauv proportional mix, nrog rau ib tug 0.018 ″ guidewire starter kit.

Pediatric / lean Adult Specialty:23G × 150 mm raws li thaub qab.

Cov neeg siv khoom OEM txawv teb chaws:Customizable ntev, connector (Luer plam vs. Luer xauv), ntim (ib tus neeg ntawv-plastic hnab / blister box), thiab ntau hom lus IFU rau ib tus neeg siv khoom kos duab.

Qhia cov neeg siv khoom kom xaj raws li "22G rau PTC cholangiography vs. 21G-22G rau PTCD ua ntej- dhau vs. ncua ntev rau cov neeg mob rog" tsis tsuas yog txhim kho kev txaus siab rau kev kho mob tab sis kuj txo cov khoom xa rov qab / pauv los ntawm kev ua yuam kev tshwj xeeb.
