Yandiswa PTFE -Izinto zeBiomedical Polymer
Ipolytetrafluoroethylene eyandisiweyo (PTFE) yinoveli yemathiriyeli yonyango ephuma kwi-polytetrafluoroethylene resin ngokuzolula kunye nezinye iindlela ezikhethekileyo zokusetyenzwa. Inombala omhlophe, u-elastiki, kunye nendalo ebhetyebhetye, inesakhiwo sothungelwano esenziwe ziifiber ezincinci ezidityanisiweyo ezenza iipores ezininzi. Esi sakhiwo esikhethekileyo se-porous sivumela ukwandiswa PTFE (ePTFE) ukugoba ngokukhululekileyo ngaphezulu kwe-360 ° ngelixa ebonisa ukuhambelana okugqwesileyo kwegazi kunye nokumelana nokwaluphala kwebhayoloji. Ngenxa yoko, ifumana ukusetyenziswa okubanzi kwimveliso yemithambo yegazi eyenziweyo, amabala entliziyo, kunye nezinye iimveliso zonyango. Ukusuka kwimbono yezonyango, imele indawo efanelekileyo yeethishu zebhayoloji ngenxa ye-biocompatibility yayo ekhethekileyo kunye ne-microporous architecture. Ngokucacileyo ayinazo iipropathi ezinetyhefu okanye i-carcinogenic kunye neziphumo ze-allergenic, iiseli zezicubu zomntu kunye nemithambo yegazi inokukhula ibe yi-micropores yayo ukuseka unxibelelwano lwethishu olufana nezicubu ezizihambelayo.
Umsebenzi Wezonyango
Yandisiwe PTFE utyando lwezicubu ezithambileyo, ezaziwa ngokuba yi-e-PTFE indawo yotyando, yenziwe lutyando olude lweeathom zekhabhoni ezigqunywe ziiathom zefluorine. Ubume bayo obukhethekileyo bemolekyuli buyenza ikwazi ukuzinza ngendlela engaqhelekanga ngokwasemzimbeni nakwimichiza, nto leyo eyenza ibe yinto eyenziweyo eneempawu ezimangalisayo. Ngaphezu koko, emva kokufakwa kwiindawo ezahlukeneyo ezifana nemithambo yegazi eyenziweyo, iinwebu ezenziweyo ezihlala ngaphakathi, kunye namabala entliziyo ngaphezu kweminyaka engama-40 nakwizi-6 zezigidi zeemeko zeklinikhi, akukho ziganeko zokwaliwa kwezonyango zichaziweyo. Obu bungqina bubanzi bubonisa ngokupheleleyo i-biocompatibility egqwesileyo yesi sixhobo.
Umgaqo-siseko weSicelo
Yandisiwe PTFE (ePTFE) iveliswa kwi-dispersion resin ye-polytetrafluoroethylene ngokusebenzisa ubuchule obukhethekileyo bokucubungula, okukhokelela kwi-ultrastructure ebonakaliswe "yi-junctions kunye ne-fibers." Ngokulawula isithuba phakathi kwezi ndibano, ukukhula kwangaphakathi kweeseli zethishu kunokukhuthazwa. Ngenxa yoko, umahluko ophambili phakathi kokusetyenziswa kwe-ePTFE njengento yokuzalisa kunye nezinye iindlela zangaphambili zilele kwindlela yokuphilisa izicubu. Ngokukodwa, ePTFE ikhuthaza ukuvuselelwa kwezicubu ngokukhula kweselula, ngelixa irabha ye-silicone yendabuko inceda ukuphilisa nge-fiber encapsulation. Ngenxa yoko, iinkqubo zokwandisa izicubu ezithambileyo zisebenzisa esi sixhobo zibonelela ngezibonelelo ezinjengokwenyani eyongeziweyo kunye nenkangeleko yendalo, ukufuduswa okuncinci kweprosthesis okanye ukuthotywa, kunye nokunciphisa umngcipheko weengxaki. Ukongezelela, ngenxa yokungeniswa okulinganiselweyo kwezicubu zeselula kwii-micropores zayo, ukususwa kwezinto xa kuyimfuneko kuthe ngqo.
Ukusetyenziswa kwemimandla emininzi ye-e-PTFE
Ilaphu eliphezulu lokusebenza
Isivakalisi esihlaziyiweyo: Iifilimu ze-GORE™ zikhaphukhaphu, zomelele, azingeni manzi, zingena moya kwaye zinokusetyenzwa zibe ngamalaphu ahlukeneyo avuzayo okanye “aphefumlayo”.
