imveliso

Ukwenza inaliti engcono, kwaye ke amava angcono ngelixa oogqirha besebenzisa i-sutures kutyando.Iinjineli kwimizi-mveliso yezixhobo zonyango zazama ukwenza inaliti ibe bukhali, yomelele kwaye ikhuseleke kumashumi eminyaka adlulileyo.Injongo kukuphuhlisa iinaliti ze-sutures kunye nokusebenza okunamandla, okubukhali kungakhathaliseki ukuba mangaphi na ukungena okufuneka kwenziwe, uninzi olukhuselekileyo olungazange lwaphule incam kunye nomzimba ngexesha lokudlula kwizicubu.Phantse lonke ibakala eliphambili lealloyi lavavanywa ukusetyenziswa kwiinaliti zokuthunga ukuze kwenziwe ngasentla kwenzeke.Olunye uphawu lwamazwe ngamazwe lusebenzisa ialloyi yomgangatho okhethekileyo inezinto ezinqabileyo zesinyithi ezinqabileyo zokugcina le njongo.

Uqoqosho kunye nokufikeleleka rhoqo kukhetho lwemarike.I-alloy yesithixo se-sutures ayilula ukusetyenzwa kunye nokuveliswa okuzisa iindleko eziphezulu.Kwelinye icala, ayilulo lonke utyando olunesicelo kulo msebenzi wenaliti ungentla.Nditsho nabanye oogqirha botyando bathanda inaliti kancinci kancinci.Ukuchaza ubukhali benaliti ngoVavanyo lwe-Penetration Force, ukuchaza amandla yenaliti ngovavanyo lwe-Bending Moment, ukuchaza ukhuseleko ngovavanyo lwe-Ductility.Ukuphucula ukusebenza kwePenetration Force, ukuchaneka kunye neteknoloji yokugaya encinci yaziswa kwishishini eligcina le njongo.Umceli mngeni kukwenza ibhalansi phakathi kokugoba umzuzwana kunye ne-Ductility, ekubeni i-alloy ihamba e-ethe-ethe ngelixa yenza kube nzima ukuba yomelele, kwaye oku kugqiba ukukhetha kwe-alloy.

Uninzi lweenaliti ze-sutures zenziwe yi-ANSI 302/304 i-alloy ngoku, ngaphambi kwe-ANSI 302/304, i-alloy ye-400 series yayisetyenziswa ngokubanzi kwiinaliti ze-Sutures kwiminyaka emashumi, kuquka i-420J2, i-455F kunye ne-470.

I-420J2 yeyona alloy yezoqoqosho kwiinaliti ze-sutures.Intsimbi ye-420J2 yintsimbi ye-martensitic engenasici, isetyenziswe emva kokucima kunye nokuvutha.Ukusebenza okubandayo kunye nokusebenza kwe-welding akulungile, emva kwe-welding kufuneka kube ngoko nangoko unyango lobushushu, ukuthintela ukuqhekeka.Inokusebenza kakuhle phantsi kwemeko yokufunxa.

I-alloy 455 yintsimbi yokuguga eyenziwe lukhuni, ene-annealing state, enokwakheka, kuphela unyango olulula lobushushu, unokufumana amandla anqabileyo aphezulu, ukuqina okulungileyo kunye nokuqina.I-Custom 455 inokucutshungulwa kwimo edibeneyo kwaye inokudityaniswa njengemvula eqinile yentsimbi engenasici.Njengoko izinga lokuqiniswa komsebenzi lincinci, linokuba neentlobo ezahlukeneyo zokubumba.I-alloy 470 ikwayintsimbi ekhethekileyo ephathwayo ye-martensitic, ebonelela ngenaliti enzima.

Utyando lwe-Cardiac kunye ne-Vascular lufuna ukusebenza ngcono njengoko kungasentla kunye ne-ophthalmic sutures, eyenziwa yi-302/304 ingxubevange.Uninzi lotyando kwisebe elingxamisekileyo akukho mfuneko yesicelo esinjalo esiphezulu esenziwa kakhulu yi-420J2 kunye ne-455 inaliti, iikhowudi ezimbalwa kuphela ezenziwe nge-alloy ye-470.
