PTC Needles (percutaneous transhepatic cholangiography koob) yog hom Class III siab - cov cuab yeej kho mob uas muaj feem cuam tshuam ncaj qha rau daim siab, lub cev muaj vascular heev, thiab nkag mus rau hauv cov kab mob biliary. Txhua yam tsis xws luag thaum lawv siv - txawm tias nws yog rab koob tip spurs, raj lumen blockage, kev sib txuas txuas, lossis cov khoom siv biocompatibility teeb meem - tuaj yeem ua rau lub neej ncaj qha - hem cov teeb meem xws li hemorrhage loj, cholestatic peritonitis, thiab sepsis. Yog li ntawd, rau cov chaw tsim khoom ntawm PTC Koob, kev tswj xyuas zoo tsis yog tsuas yog kev tshuaj xyuas cov khoom yooj yim xwb; Nws yog ib qho kev ua haujlwm zoo tshaj plaws nyob rau hauv kev tiv thaiv kev pheej hmoo, khiav thoob plaws tag nrho cov khoom lag luam, raws li ISO13485 tus qauv thoob ntiaj teb.

I. Tsim Kev Tswj: Tsis txhob muaj kev pheej hmoo ntawm qhov chaw

Kev zoo pib nrog tsim. Txawm hais tias muaj kev cai tshwj xeeb, cov tuam txhab lag luam yuav tsum pib tsim cov txheej txheem tswj hwm nruj.

• Risk analysis thiab design input:Rau daim ntawv thov kev kho mob ntawm PTC koob (percutaneous daim siab puncture), txheeb xyuas tag nrho cov kev pheej hmoo: puncture tsis ua hauj lwm, tsis ua hauj lwm vascular puncture, bile duct raug mob, nyuaj nyob rau hauv guidewire passage, contrast agent extravasation, instrument fracture thiab residue, thiab lwm yam. Hloov cov kev pheej hmoo no rau hauv cov kev xav tau tshwj xeeb tsim tawm: xws li cov kev xav tau ntawm kev sib tw thiab lub kaum ntse ntse. koob raj, qhov tsawg kawg nkaus sab hauv txoj kab uas hla ntawm lub lumen, tawg siab ntawm qhov txuas, corrosion kuj ntawm cov khoom, thiab lwm yam.
• Tsim kev txheeb xyuas thiab kev pom zoo:Tshawb xyuas los ntawm kev ntsuam xyuas engineering seb cov khoom puas ua tau raws li cov qauv tsim tawm (xws li kev ntsuas kev quab yuam, kev ntsuas kev ntsuas kev hla dhau). Paub meej tias cov khoom muaj peev xwm ua tau raws li kev xav tau ntawm kev kho mob los ntawm kev siv simulation lossis kev soj ntsuam kuaj mob (yog tias tsim nyog). Piv txwv li, siv cov ntaub so ntswg -zoo li lub siab qauv, qhov muag tsis pom kev kuaj yog ua los ntawm cov kws kho mob uas paub txog los ntsuas qhov kev tawm tswv yim tactile thiab puncture ua tau zoo.

II. Kev Tswj Xyuas Txheej Txheem Ntau Lawm: Tshem tawm cov kev pheej hmoo hauv kev tsim khoom

Kev tsim khoom yog tus yuam sij rau kev hloov cov qauv tsim rau hauv cov khoom siv lub cev, thiab nws kuj yog qhov kev sib ntaus sib tua tseem ceeb rau kev tswj hwm kev pheej hmoo.

Cov txheej txheem tshwj xeeb lees paub:"Txiav thiab shaping", "Core ntau lawm", "Tube kab noj hniav tsim" thiab lwm yam txheej txheem nyob rau hauv PTC koob manufacturing yog tag nrho cov txheej txheem tshwj xeeb. Lawv cov txiaj ntsig tsis tuaj yeem txheeb xyuas tag nrho los ntawm kev tshuaj xyuas tom ntej. Cov neeg tsim khoom yuav tsum ua cov txheej txheem validation los ua pov thawj tias lawv tuaj yeem tsim cov khoom tsim nyog raws li cov txheej txheem teeb tsa. Piv txwv li, txiav txim siab qhov zoo tshaj plaws lub zog, ceev thiab focal nrug rau laser welding koob tuav, thiab ua li niaj zaus re-validation.

Cov ntsiab lus tseem ceeb ntawm cov txheej txheem tswj:

• Koob tip grinding:Symmetry, sharpness thiab tsis muaj burrs ntawm koob taub yog qhov tseem ceeb tshaj plaws. Siab - lub hwj chim microscopes lossis cov khoom siv kho qhov muag tsis siv neeg yuav tsum tau siv rau 100% kev tshuaj xyuas tag nrho.
• Sab hauv kab noj hniav polishing:Lub smoothness ntawm lub raj kab noj hniav ncaj qha cuam tshuam rau kev ua haujlwm. Kev soj ntsuam kuaj kab mob endoscopy thiab kuaj kab mob yuav tsum tau ua.
• Tube core matching:Lub zog ntawm kev ntxig thiab tshem tawm cov tub ntxhais tub ntxhais yuav tsum tau tswj nyob rau hauv ib qho kev tshwj xeeb, tsis tas yuav xoob los ua detachment los yog nruj heev rau kev ua haujlwm. Cov cuab yeej ntsuas tshuab yuav tsum tau siv rau kev saib xyuas.
• Ntxuav thiab particle tswj:Residual micro-particles tsim thaum lub sij hawm ua hlau yog qhov txaus ntshai heev. Kev ntxuav zaum kawg yuav tsum tau ua nyob rau hauv ib lub rooj cob qhia huv, thiab kev kuaj kab mob sib kis ntawm cov khoom ntxuav yuav tsum tau ua kom ua raws li cov qauv tshuaj pharmacopoeia.

Traceability:Los ntawm batch naj npawb ntawm kev kho mob - qib stainless hlau rods yuav, mus rau ntau lawm batch naj npawb, cov khoom siv, thiab cov ntaub ntawv tus neeg teb xov tooj ntawm txhua koob, tag nrho cov yuav tsum tau sau tseg nyob rau hauv lub txheej txheem kom ua tiav rau pem hauv ntej thiab rov qab traceability.

III. Sterilization thiab ntim: Ua kom muaj kev nyab xeeb zaum kawg

PTC koob yog cov khoom tsis muaj menyuam. Txoj kev ua kom tsis muaj menyuam thiab ntim khoom yog qhov kawg thiab tseem ceeb ntawm kev kuaj xyuas kev nyab xeeb ua ntej cov khoom tawm hauv lub hoobkas.

• Sterilization pov thawj:Feem ntau siv ethylene oxide sterilization yuav tsum tau ua tiav cov txheej txheem pov thawj, suav nrog kev sim tshuaj tua kab mob, kev sim ntsuas kev sib tw lom neeg, thiab lwm yam, kom ntseeg tau tias qib sterility ntawm 10.^-6tuaj yeem ua tiav txawm tias nyob rau hauv qhov nyuaj tshaj plaws -kom- ua kom tsis muaj menyuam. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xyuas kom meej tias cov txheej txheem kom tsis muaj menyuam tsis cuam tshuam rau qhov ntse ntawm rab koob, cov khoom siv, thiab cov txheej txheem (yog tias muaj).
• Packing Verification:Kev ntim khoom (thawj lub ntim ntim hauv "Standard carton") yuav tsum muaj peev xwm tswj tau cov khoom tsis muaj menyuam thaum caij tsheb thauj mus los, khaws cia, thiab mus txog thaum siv. Kev ntsuam xyuas kev ntseeg siab ntawm ntim khoom (xws li staining thiab permeation method) thiab simulated kev kuaj tsheb thauj mus los yuav tsum tau ua kom paub tseeb tias nws tuaj yeem tiv thaiv cov khoom hauv qhov hnyav.

IV. Tshaj tawm- teev Kev Saib Xyuas: Kaw-loop Management of Risks

Kev tswj xyuas zoo tsis tuaj yeem xaus vim tias cov khoom tsim tawm.

• Saib xyuas thiab qhia txog cov xwm txheej tsis zoo:Cov neeg tsim khoom yuav tsum tsim kom muaj ib qho system los sau cov xwm txheej tsis zoo uas cuam tshuam nrog cov khoom lag luam thoob ntiaj teb, txheeb xyuas cov hauv paus hauv paus, thiab tshaj tawm rau cov thawj coj tswj hwm raws li cov cai.
• Kev kho thiab tiv thaiv kev ua:Rau ib qho teeb meem uas muaj peev xwm lossis twb tau tshwm sim lawm, pib txheej txheem CAPA, ua qhov kev txhim kho tseem ceeb los ntawm kev tsim lossis kev tsim khoom kawg, thiab tiv thaiv kev rov tshwm sim.
• Kev tshuaj xyuas tsis tu ncua:Tsis tu ncua rov- soj ntsuam tag nrho cov kev pheej hmoo ntawm cov khoom lag luam kom ntseeg tau tias kev tswj hwm kev pheej hmoo tsis muaj zog thiab tsis tu ncua.

Yog li ntawd, ib lub tuam txhab PTC Needles uas ua raws li ISO13485 tus qauv, nws lub Hoobkas yog qhov tseem ceeb ntawm kev tswj hwm kev pheej hmoo uas saib xyuas kev nyab xeeb ntawm tus neeg mob ua ntej, ua cov ntaub ntawv - tsav kev txiav txim siab, thiab tsom rau kev tiv thaiv. Nws lub tuam tsev ua haujlwm zoo tsis yog "tub ceev xwm", tab sis yog "engineers" thiab "cov kws kho mob", ua haujlwm ib sab nrog cov chaw tsim khoom thiab kev tshawb fawb thiab kev loj hlob. Txhua PTC koob tsim los ntawm lawv nqa ib txheej ntawm cov ntaub ntawv zoo thiab cov ntaub ntawv tswj kev pheej hmoo. Qhov kev nrhiav siab heev ntawm "zero defects" tsis yog rau kev lees paub xwb, tab sis yog los ntawm kev hwm rau qhov siab -kev pheej hmoo ib puag ncig uas cov khoom nkag mus rau - tib neeg lub siab. Qhov no yog qhov laj thawj tseem ceeb vim li cas cov tuam ntxhab tuaj yeem muab kev ntseeg siab rau cov kws kho mob, thiab nws tseem yog lub hauv paus tseem ceeb uas lawv tuaj yeem muaj sia nyob hauv kev sib tw ua lag luam hnyav.
