Umthungo obambekayo
Ama-Sutures abambekayo aphinde ahlukaniswe abe: amathumbu, ama-chemical synthesized (PGA), nama-collagen sutures emvelo ahlanzekile kuye ngezinto kanye nezinga lokumuncwa.
1. Amathumbu ezimvu: Enziwa ngamathumbu ezimvu esilwane esinempilo kanye namathumbu embuzi futhi aqukethe izingxenye ze-collagen.Ngakho-ke, akudingekile ukususa intambo ngemuva kwe-suturing.Ulayini wamathumbu wezokwelapha: ulayini ojwayelekile wamathumbu kanye nolayini we-chrome gut, womabili angamuncwa.Ubude besikhathi esidingekayo sokumuncwa buncike ekushubeni kwamathumbu kanye nesimo sethishu.Ivamise ukumuncwa izinsuku eziyisi-6 kuye kwezingama-20, kodwa umehluko ngamunye uthinta inqubo yokumuncwa noma ngisho nokumunca.Njengamanje, amathumbu enziwe ngamaphakheji e-aseptic alahlwayo, okulula ukuwasebenzisa.
(1) Amathumbu avamile: ithumbu elimunca kalula elenziwe ngezicubu ze-submucosal zesisu noma ithumbu lenkomo.Ukumuncwa kuyashesha, kodwa izicubu zisabela kancane emathunjini.Ivame ukusetshenziselwa ukuphulukisa imithambo yegazi ngokushesha noma izicubu ezingaphansi kwe-ligature yegazi kanye namanxeba angenwe yi-suture.Ivame ukusetshenziswa ezingqimbeni ze-mucosal ezifana nesibeletho nesinye.
(2) I-Chrome gut: Lawa mathumbu enziwa ukwelashwa kwe-chromic acid, okunganciphisa izinga lokumuncwa kwezicubu, futhi kubangele ukuvuvukala okuncane kunethumbu elivamile.Ngokujwayelekile isetshenziselwa ukuhlinzwa kwezifo zabesifazane kanye nomchamo, i-suture evame ukusetshenziswa ekuhlinzeni izinso kanye ne-ureter, ngoba usilika uzokhuthaza ukwakheka kwamatshe.Gcoba emanzini anosawoti ngesikhathi sokusebenzisa, qondisa ngemva kokuthambisa, ukuze kube lula ukusebenza.
I-2, ulayini wokuhlanganisa amakhemikhali (i-PGA, i-PGLA, i-PLA): i-polymer linear material eyenziwe ngobuchwepheshe bamakhemikhali besimanje, ngenqubo yokudweba, ukumboza nezinye izinqubo, ngokuvamile emuncwa phakathi kwezinsuku ezingu-60-90, ukuzinza kokumuncwa.Uma kuyimbangela yenqubo yokukhiqiza, kunezinye izingxenye zamakhemikhali ezingaboli, ukumuncwa akuphelele.
I-3, i-collagen suture yemvelo ehlanzekile: ethathwe ku-tendon yezilwane ezikhethekile ze-raccoon, okuqukethwe okuphezulu kwe-collagen yemvelo, inqubo yokukhiqiza ngaphandle kokubamba iqhaza kwezingxenye zamakhemikhali, inezici ze-collagen;okwesizukulwane samanje sesine seqiniso se-sutures.Inokumuncwa okuphelele, amandla aqine kakhulu, i-biocompatibility enhle, futhi ikhuthaza ukukhula kwamangqamuzana.Ngokusho kobukhulu bomzimba womugqa, ngokuvamile uthatha izinsuku ezingu-8-15, futhi ukumuncwa kuzinzile futhi kunokwethenjelwa, futhi awukho umehluko osobala womuntu ngamunye.
