Umthungo ofunxayo
I-Sutures absorbable iphinda ihlulwe ibe: amathumbu, i-chemically synthesized (PGA), kunye ne-collagen sutures yendalo ecocekileyo ngokuxhomekeke kwizinto kunye neqondo lokufunxa.
1. Amathumbu egusha: Enziwa ngamathumbu egusha kunye namathumbu ebhokhwe asempilweni kwaye aqulethe izinto zecollagen.Ngoko ke, akuyimfuneko ukususa intambo emva kwe-suturing.Umgca wamathumbu wonyango: umgca we-gut oqhelekileyo kunye nomgca we-chrome gut, zombini unokufunxwa.Ubude bexesha elifunekayo lokufunxa kuxhomekeke kubukhulu bamathumbu kunye nemeko yezicubu.Ngokuqhelekileyo ifunxa kangangeentsuku ezi-6 ukuya kwezingama-20, kodwa umahluko ngamnye uchaphazela inkqubo yokufunxa okanye ukufunxa.Okwangoku, amathumbu enziwe ngepakethe ye-aseptic elahlayo, elula ukuyisebenzisa.
(1) Ithumbu eliqhelekileyo: Ithumbu elifunxa ngokulula elenziwe kwithishu engaphantsi kwe-submucosal yomathumbu okanye ithumbu lenkomo.Ukufunxa ngokukhawuleza, kodwa izicubu ziphendula kancinci emathunjini.Ihlala isetyenziselwa ukuphilisa imithambo yegazi ngokukhawuleza okanye izicubu ezingaphantsi kwe-ligature kwimithambo yegazi kunye namanxeba asulelekileyo.Isetyenziswa ngokuqhelekileyo kwiingqimba ze-mucosal ezifana nesibeleko kunye nesinyi.
(2) I-Chrome gut: Eli thumba lenziwe ngonyango lwe-chromic acid, olunokuthi lucothise izinga lokufunxa kwezicubu, kwaye lubangela ukudumba okuncinci kunomathumbu oqhelekileyo.Ngokuqhelekileyo isetyenziselwa utyando lwe-gynecological kunye ne-urinary, yi-suture ehlala isetyenziselwa utyando lwezintso kunye ne-ureter, kuba i-silika iya kukhuthaza ukubunjwa kwamatye.Gxila emanzini anetyuwa ngexesha lokusetyenziswa, lungisa emva kokuthambisa, ukwenzela ukuba kube lula ukusebenza.
I-2, umgca we-chemical synthesis (PGA, PGLA, PLA): i-polymer linear material eyenziwe yiteknoloji yekhemikhali yanamhlanje, ngokusebenzisa inkqubo yokudweba, ukugquma kunye nezinye iinkqubo, ngokuqhelekileyo zixutywe kwiintsuku ezingama-60-90, ukuzinza kwe-absorption.Ukuba yimbangela yenkqubo yokuvelisa, kukho amanye amacandelo ekhemikhali angenakonakala, ukufunxa akuphelelanga.
I-3, i-collagen yemvelo ecocekileyo ye-suture: ithathwe kwi-tendon ye-raccoon yezilwanyana ezikhethekileyo, umxholo ophezulu we-collagen wendalo, inkqubo yokuvelisa ngaphandle kokuthatha inxaxheba kwamacandelo ekhemikhali, ineempawu ze-collagen;kwisiZukulwana sesine sokwenyani sangoku se-sutures.Inokufunxa ngokupheleleyo, ukomelela okuphezulu, ukuhambelana kakuhle kwe-biocompatibility, kwaye ikhuthaza ukukhula kweeseli.Ngokobunzima bomzimba womgca, ngokuqhelekileyo ufunxa iintsuku ezi-8-15, kwaye ukufunxa kuzinzile kwaye kuthembekile, kwaye akukho mahluko acacileyo.
