Kushandiswa kweMedical Alloy inoshandiswa pane Sutures tsono
Kuita tsono iri nani, uyezve zviitiko zviri nani apo vanachiremba vanovhiya vanoisa sutures mukuvhiya. Mainjiniya muindasitiri yemidziyo yekurapa vakaedza kuita kuti tsono ive inopinza, yakasimba uye yakachengeteka mumakumi emakore apfuura. Chinangwa ndechekugadzira tsono dzesutures dzine simba rakasimba, rakapinza zvisinei kuti mapindiro mangani anofanirwa kuitwa, akachengeteka zvakanyanya asina kumbopwanya muromo uye muviri panguva yekupfuura nemumatishu. Anenge ese magiredhi makuru ealloy akayedzwa mashandisirwo pasutures tsono dzekugadzira pamusoro zvakaitika. Imwe mhando yemarudzi akawanda inoshandisa yakakosha giredhi alloy ine isingawanzo simbi yakakosha masimbi kuchengetedza chinangwa ichi.
Economic uye inokwanisika nguva dzose sarudzo yemusika. Iyo chidhori alloy ye sutures haisi nyore kugadzirisa uye kugadzira iyo inounza mutengo wakakwira. Nerumwe rutivi, havasi vese vekuvhiya vane chikumbiro pamusoro pekuita tsono. Kunyange vamwe vanachiremba vanofarira tsono zvishoma zvishoma. Kutsanangura kupinza kwetsono kuburikidza nePenetration Force Test, kutsanangura kusimba kwetsono kuburikidza neBending Moment bvunzo, kutsanangura kuchengetedza kuburikidza neDuctility bvunzo. Kuvandudza kuita kwePenetration Force, kunyatsoita uye tekinoroji yekukuya yakaunzwa kune maindasitiri akachengetedza chinangwa ichi. Dambudziko nderekuita chiyero pakati peBending Moment uye Ductility, sezvo alloy ichienda isina kusimba ichiita kuti zviome kusimba, uye izvi zvinosarudza sarudzo yealloy.
Mazhinji masino tsono akagadzirwa ne ANSI 302/304 alloy ikozvino, pamberi pe ANSI 302/304, 400 akatevedzana alloy aishandiswa zvakanyanya kune Sutures tsono kwemakumi emakore, kusanganisira 420J2, 455F uye 470.
420J2 ndiyo yakanyanya hupfumi alloy kune sutures tsono. 420J2 simbi martensitic simbi isina tsvina, inoshandiswa mushure mekudzima uye kupisa. Cold kushanda kuita uye welding kuita hakuna kunaka, mushure mekugadzira kunofanirwa kuve nekukurumidza kupisa kurapwa, kudzivirira kuputika. Iyo ine yakanaka machinability pasi pe annealing mamiriro.
Alloy 455 is a martensitic kuchembera yakaomeswa simbi isina tsvina, ine yakapfava, annealing state inogona kuumbwa, chete iri nyore kupisa kupisa, unogona kuwana yakasarudzika yakakwirira tensile simba, kunaka kuoma uye kuoma. Tsika 455 inogona kugadziriswa mu annealed state uye inogona kuvezwa semvura yakaomeswa simbi isina tsvina. Sezvo basa kuomesa mwero idiki, anogona kuva siyana kutonhora kuumba. Alloy 470 zvakare yakakosha kurapwa martensitic simbi isina tsvina, iyo inopa yakaoma tsono.
Kuvhiyiwa kweMwoyo neVascular kunoda kushanda kuri nani sezviri pamusoro pamwe chete neophthalmic sutures, yakagadzirwa ne302/304 alloy. Kuvhiya kwakawanda mudhipatimendi rekukurumidzira hakudi chikumbiro chakadaro chakanyanya kuitwa ne420J2 uye 455 tsono, mashoma macode akaitwa ne470 alloy.
