Izicubu Ezimuncwayo

I-suture emuncwayo
Ama-sutures adonswayo ahlukaniswe kabanzi ngokuthi: amathumbu, akhiwe ngamakhemikhali (i-PGA), kanye nama-sutures e-collagen yemvelo amsulwa kuye ngokuthi izinto ziyini kanye nezinga lokumuncwa.
1. Amathumbu ezimvu: Enziwe ngamathumbu ezimvu nawembuzi aphilile futhi aqukethe izingxenye ze-collagen. Ngakho-ke, akudingekile ukususa intambo ngemva kokuthungwa. Umugqa wamathumbu wezokwelapha: umugqa wamathumbu avamile kanye nomugqa wamathumbu we-chrome, kokubili kungamuncwa. Ubude besikhathi esidingekayo ukuze kumuncwe buxhomeke ekujiyeni kwamathumbu kanye nesimo sezicubu. Ngokuvamile kumuncwa izinsuku ezingu-6 kuya kwezingu-20, kodwa umehluko ngamunye uthinta inqubo yokumuncwa noma ngisho nokumuncwa. Njengamanje, amathumbu enziwe ngephakheji ye-aseptic elahlwayo, okulula ukuyisebenzisa.
(1) Amathumbu avamile: umthungo okwazi ukumuncwa kalula owenziwe ngezicubu ezingaphansi kwesisu noma amathumbu ezinkomo. Ukumuncwa kuyashesha, kodwa izicubu zisabela kancane emathunjini. Ngokuvamile kusetshenziselwa ukwelapha imithambo yegazi noma izicubu ezingaphansi kwesikhumba ngokushesha emithanjeni yegazi ehlanganisiwe kanye nokuthungwa kwamanxeba athelelekile. Ngokuvamile isetshenziswa ezingqimbeni ze-mucosal njengesibeletho kanye nesinye.
(2) Amathumbu e-Chrome: La mathumbu enziwa ngokwelashwa nge-chromic acid, okunganciphisa izinga lokumuncwa kwezicubu, futhi kubangele ukuvuvukala okuncane kunokuhlinzwa okuvamile kwamathumbu. Ngokuvamile isetshenziselwa ukuhlinzwa kwabesifazane kanye nomchamo, iyisithungo esivame ukusetshenziswa ekuhlinzeni kwezinso kanye nomchamo, ngoba usilika uzokhuthaza ukwakheka kwamatshe. Cwilisa emanzini anosawoti ngesikhathi sokusebenzisa, uqondise ngemva kokuthamba, ukuze kube lula ukuhlinzwa.
2, umugqa wokwenziwa kwamakhemikhali (i-PGA, i-PGLA, i-PLA): into eqondile ye-polymer eyenziwe ngobuchwepheshe bamakhemikhali besimanje, ngenqubo yokudweba, ukumboza nezinye izinqubo, ngokuvamile emuncwa zingakapheli izinsuku ezingama-60-90, ukuzinza kokumuncwa. Uma kuyimbangela yenqubo yokukhiqiza, kunezinye izingxenye zamakhemikhali ezingaboli, ukumuncwa akukapheleli.
3, i-collagen suture yemvelo emsulwa: ethathwe ku-tendon ekhethekile ye-raccoon yesilwane, okuqukethwe okuphezulu kwe-collagen yemvelo, inqubo yokukhiqiza ngaphandle kokuhlanganyela kwezingxenye zamakhemikhali, inezici ze-collagen; yesizukulwane sesine sangempela samanje se-sutures. Inomuncwa ophelele, amandla aphezulu okudonswa, ukuhambisana okuhle kwezinto eziphilayo, futhi ikhuthaza ukukhula kwamaseli. Ngokusho kobukhulu bomzimba womugqa, ngokuvamile imuncwa izinsuku ezingu-8-15, futhi ukumuncwa kuzinzile futhi kuthembekile, futhi akukho mehluko ocacile womuntu ngamunye.
