Ukwenziwa kwezinto zokufakelwa kwezonyango yintsimi apho ukuchaneka kungekuphela nje komlinganiselo—yimfuno yokhuseleko lwesigulana. I-Titanium, izinto ezisemgangathweni zegolide zokufakelwa kwamathambo ngenxa yokuhambelana kwayo kunye namandla ayo, inika iseti ekhethekileyo yemingeni yemetrological. Ngokungafaniyo nezinto eziqhelekileyo zezithuthi okanye zeenqwelo-moya, ukulinganisa izinto zokufakelwa kwetitanium kufuna indlela ekhethekileyo yokuqinisekisa ukuchaneka, ukungazali, kunye nokuthotyelwa kwemithetho.
Apha kwi-ZHHIMG, siyaqonda ukuba i-metrology yezixhobo zonyango ifuna okungaphezulu kwezixhobo eziqhelekileyo. Nazi iingxaki ezintathu eziqhelekileyo ekulinganiseni i-titanium implants kunye nezisombululo zobugcisa ezifunekayo ukuze zisombululwe.
1. Umngeni wokulinganisa okungengoMagnetic
I-Titanium ayinamandla kwaye ayinamandla. Nangona oku kuluncedo kwisigulana (ingakumbi kwiindawo ze-MRI), kuyayenza nzima inkqubo yokulinganisa. Iibhloko ze-gauge zentsimbi eziqhelekileyo okanye ii-chucks ze-magnetic zinokubangela ukuphazamiseka okanye zingaphumeleli ukubamba i-geometry ethambileyo yento yovavanyo ngexesha lokulinganisa.
- Isisombululo: Indawo yokulinganisa engenamagnethi ngokupheleleyo. Sicebisa ukusetyenziswa kweebhloko ze-ceramic gauge kunye nemiphetho ethe tye ye-ceramic. Ngokungafaniyo nentsimbi, i-zirconia ceramic yodidi oluphezulu ayinamagnethi ngokupheleleyo, iqinisekisa ukuba akukho mandla emagnethi aphazamisana nokulinganiswa kweempawu zangaphakathi ze-implant. Oku kubalulekile ekulinganisweni kwe-titanium implant apho nokuba ngumtsalane we-microscopic magnetic unokuphazamisa iziphumo.
2. Iijometri ezintsonkothileyo kunye neendawo zendalo
Izinto ezifakelwayo kwezonyango zenzelwe ukulinganisa umzimba womntu. Isiqu sesinqe okanye idolo lidla ngokuba neegophe ezintsonkothileyo, eziphilayo kunye neendawo ezinemingxuma ezenzelwe ukukhula kwamathambo (i-osseointegration). Ukulinganisa ezi ndawo "zikhululekileyo" ngokunyamezela okuqinileyo (ngokuqhelekileyo ±0.025mm) kusetyenziswa izixhobo zesandla zemveli phantse akunakwenzeka.
- Isisombululo: Ii-Multi-sensor Coordinate Measuring Machines (CMM) ezidityaniswe ne-custom fixturing.
- UkuHlola okuBonisayo nokuThathayo: Ngelixa ii-tactile probes zilinganisa amanqaku athile, ii-optical sensors zinokumakisha iprofayili yomphezulu ontsonkothileyo ngaphandle kokuchukumisa kwaye zingonakalisa umphezulu we-titanium othambileyo.
- Izinto ezenziwe ngokwezifiso: Ukuqinisekisa ukuba inxalenye ibanjwe kwindawo enokuphindaphindwa, izinto ezenziwe ngokwezifiso ze-ceramic okanye ze-granite zibalulekile. Zibonelela ngozinzo olufunekayo kwi-CMM ukuze ikwazi ukumakisha ngokuchanekileyo ii-angles ze-5° ezigobileyo kunye neeprofayili zomphezulu.
3. Ucoceko kunye noLawulo loNgcoliseko
Izinto ezifakelweyo kwezonyango kufuneka zenziwe kwaye zilinganiswe kwiindawo ezilawulwayo (ngokuqhelekileyo ii-ISO Class 7 okanye 8 cleanrooms). Iipleyiti zesinyithi ezisemgangathweni zinokugqwala, zikhuphe amasuntswana amancinci angcolisa i-implant. Ngokufanayo, izinto ezinemingxuma zinokuba neentsholongwane.
- Isisombululo: I-Granite kunye ne-Ceramic ezihambelana negumbi lokucoca.
- Iipleyiti zomphezulu weGranite: Igranite esemgangathweni ophezulu ayibolisi kwaye izinzile ngokwendalo. Xa ivalwe ngesiphelo esikhethekileyo, inika umphezulu wokusebenza ongacocwanga, okulula ukuwucoca ohlangabezana nemigangatho yococeko ye-FDA.
- Izixhobo zeCeramic: Izixhobo zokulinganisa zeCeramic azinazo iikhemikhali kwaye ziyamelana nee-alcohol kunye nee-sterilization agents ezisetyenziswa kumagumbi okucoca. Azigqwali okanye zinyibilikise, ukuqinisekisa ukuba inkqubo yokulinganisa ngokwayo ayizisi izinto ezingcolisayo kwiindawo zonyango ezichanekileyo.
Isifundo Setyala: Ukulinganisa Isiqu Sesinqe SeTitanium
Ukuze sibonise le migaqo, cinga ngenkqubo yokulawula umgangatho wesiqu se-titanium hip.
- Inxalenye: Isiqu se-femoral esine-engile yokugoba emva kwe-5° kunye nokunyamezela iprofayili yomphezulu we-±0.05mm.
- Ukuseta: Le nxalenye ibekwe kwipleyiti yomphezulu wegranite yebanga le-00 ukuqinisekisa ukuba i-datum ayishukumi, i-flat.
- Inkqubo:
- Ukulinganisa: I-CMM ilinganiswa kusetyenziswa iibhloko ze-ceramic gauge ukuqinisekisa ukungathathi cala kobushushu kunye ne-magnetic.
- Ulungelelwaniso: Irula yesikwere se-ceramic isetyenziswa ukuqinisekisa ngesandla ulungelelwaniso olupheleleyo lwenxalenye ngaphambi kokuba iskenwe ngokuzenzekelayo.
- Ukuskena: I-CMM isebenzisa iskena selaser ukumakisha i-organic curvature, iqinisekisa ukuba i-angle yokugoba ihambelana nemodeli ye-CAD ngaphakathi kokunyamezelana kwe-±0.05mm.
Ukuthotyelwa kweMigqaliselo: Imigangatho ye-FDA kunye ne-ISO
Kwishishini lezonyango, uxwebhu lubaluleke njengomlinganiselo ngokwawo.
- I-FDA 21 CFR Icandelo 820: Ifuna ukuba zonke izixhobo zokuhlola, zokulinganisa, nezokuvavanya zilungele injongo yazo kwaye zikwazi ukuvelisa iziphumo ezifanelekileyo. Ukusebenzisa izinto ezizinzileyo ezifana ne-ceramic kunye ne-granite kunceda ukuqinisekisa uzinzo lokulinganisa ixesha elide.
- I-ISO 13485: Inkqubo yolawulo lomgangatho wezixhobo zonyango ifuna ulawulo olungqongqo kwindawo yokusebenza. Izixhobo zeseramikhi kunye nezegranite ezingaboliyo, ezicocekileyo zibalulekile ekugcineni oku kulandelwa.
