Yeyiphi inkqubo yomgangatho efunekayo kwisitampu sesinyithi sesixhobo sonyango?
ISO 13485:2016 yinkqubo yokulawula umgangatho wehlabathi jikelele kubavelisi bezixhobo zonyango. E-United States, ababoneleli kufuneka kwakhona bathobele i-FDA 21 CFR iSigaba 820 (uMmiselo weNkqubo yoBulunga). Kwiimarike ze-EU, ukuthotyelwa kwe-MDR 2017/745 kuyafuneka. Ababoneleli abaninzi balandela isatifikethi se-MDSAP ukuze banelise iimarike zolawulo ezininzi ngophicotho olunye.
Luluphi unyamezelo olunokufikelelwa kwisixhobo sonyango sokunyathela ngesitampu?
Isitampu sesixhobo sezonyango siphumeza ±0.005 mm (±0.0002 ngaphakathi.) kwiimpawu ezibalulekileyo ezifana needayamitha zemingxuma, ubukhulu bodonga, kunye nemiphezulu yokutywina. Oku kufuna izixhobo ezichanekileyo eziphantsi komhlaba, ii-servo-driven presses ezine-± 0.005 mm ukuphindaphinda, iindawo zokuvelisa ezilawulwa ngubushushu (20 ±1 °C), kunye nokuhlolwa kwe-CMM ngokuchaneka kwe-sub-micron.
Zeziphi izinto ezihambelana ne-biocompatible yesitampu sesixhobo sonyango?
Izinto ezisetyenziswa ngokuqhelekileyo ze-biocompatible isitampu ziquka i-stainless steel 316LVM (ASTM F138), i-titanium CP yeBanga lesi-2 kunye ne-Ti-6Al-4V ELI (ASTM F136), MP35N (ASTM F562), i-Elgiloy F562), i-Elgiloy (ASTM) 3, i-Elgiloy (ASTM) 3, kunye ne-F1058 Bonke kufuneka baphumelele uvavanyo lwe-ISO 10993 lwe-biocompatibility (i-cytotoxicity, i-sensitization, irritation) malunga nobude bexesha kunye nohlobo lwabo lokunxibelelana nesigulana.
Yintoni i-UDI kwaye kutheni ibalulekile kwizinto zonyango ezinesitampu?
I-UDI (Isichongi seSixhobo esiNdwa) yinkqubo egunyaziswe yi-FDA (21 CFR iSigaba 830) kunye ne-EU MDR enikezela ngesazisi esisodwa kuzo zonke izixhobo zonyango. Kumacandelo anesitampu, idatha ye-UDI - kubandakanywa inombolo yelotho, inombolo ye-serial, kunye nomhla wokuvelisa - kufuneka ilandelelwe kwaye mhlawumbi imakishwe ngokuthe ngqo kwinxalenye (yezixhobo ezinokuphinda zisetyenziswe / ezifakelwayo) okanye kwi-packaging (kwizinto ezilahlayo).
Uthini umahluko phakathi kwe-ISO 13485 kunye ne-FDA 21 CFR 820?
I-ISO 13485 ngumgangatho wamazwe ngamazwe owaziwa kwihlabathi jikelele, ngelixa i-FDA 21 CFR 820 ingummiselo othe ngqo wase-U.S. Bagubungela umhlaba ofanayo - ulawulo loyilo, ukuqinisekiswa kwenkqubo, iCAPA, ulawulo lwamaxwebhu - kodwa bahluke kwiimfuno ezithile. Umzekelo, i-FDA idinga ingxelo yesixhobo sonyango (MDR) kwiziganeko ezimbi, ngelixa i-ISO 13485 idinga ingxelo ephaphileyo ngokwegunya elisebenzayo elilawulayo. Ababoneleli abaninzi balungelelanisa inkqubo yabo yomgangatho kuzo zombini izikhokelo ukuze bakhonze iimarike zehlabathi.
