Absorbable Sutures

Suture yokhazikika
Ma sutures owoneka bwino amagawidwanso kukhala: m'matumbo, opangidwa ndi mankhwala (PGA), ndi ma collagen achilengedwe achilengedwe kutengera zakuthupi ndi kuchuluka kwa kuyamwa.
1. Matumbo a Nkhosa: Amapangidwa kuchokera ku matumbo athanzi a nkhosa ndi mbuzi ndipo amakhala ndi ma collagen. Choncho, sikoyenera kuchotsa ulusi pambuyo pa suturing. Mzere wamatumbo achipatala: mzere wamba wamatumbo ndi mzere wa chrome, zonse zimatha kuyamwa. Kutalika kwa nthawi yofunikira kuyamwa kumadalira makulidwe a m'matumbo komanso momwe minofuyo ilili. Nthawi zambiri amatengeka kwa masiku 6 mpaka 20, koma kusiyana kwake kumakhudza momwe mayamwidwe amayamwidwira kapena ngakhale kuyamwa. Pakadali pano, m'matumbo amapangidwa ndi zotayira za aseptic, zomwe ndizosavuta kugwiritsa ntchito.
(1) M'matumbo wamba: njira yosavuta kuyamwa yopangidwa kuchokera kumatumbo am'matumbo kapena matumbo a ng'ombe. Kuyamwa kumathamanga, koma minofu imayankha pang'ono m'matumbo. Nthawi zambiri amagwiritsidwa ntchito kuchiritsa mitsempha yamagazi mwachangu kapena minofu yolumikizana ndi mitsempha yamagazi ndi mabala omwe ali ndi matenda a suture. Amagwiritsidwa ntchito kwambiri pazigawo za mucosal monga chiberekero ndi chikhodzodzo.
(2) M'matumbo a Chrome: Matumbowa amapangidwa ndi mankhwala a chromic acid, omwe amatha kuchedwetsa mayamwidwe a minofu, ndipo amayambitsa kutupa pang'ono kuposa m'matumbo wamba. Kawirikawiri amagwiritsidwa ntchito pa opaleshoni ya amayi ndi mkodzo, ndi suture yomwe imagwiritsidwa ntchito nthawi zambiri pa opaleshoni ya impso ndi ureteral, chifukwa silika amalimbikitsa mapangidwe a miyala. Zilowerereni m'madzi amchere mukamagwiritsa ntchito, yongolani mutatha kufewetsa, kuti ntchitoyo ikhale yosavuta.
2, mankhwala synthesis mzere (PGA, PGLA, PLA): ndi polima liniya zakuthupi opangidwa ndi luso zamakono mankhwala, kudzera m'kati kujambula, ❖ kuyanika ndi njira zina, zambiri odzipereka mkati 60-90 masiku, mayamwidwe bata. Ngati ndizomwe zimayambitsa kupanga, pali zigawo zina zomwe sizingawonongeke, kuyamwa sikokwanira.
3, koyera zachilengedwe kolajeni suture: wotengedwa wapadera nyama raccoon tendon, mkulu zachilengedwe kolajeni zili, ndondomeko kupanga popanda kutenga nawo mbali mankhwala zigawo zikuluzikulu, ali ndi makhalidwe a kolajeni; kwa Mbadwo wachinayi weniweni wa ma sutures. Ili ndi kuyamwa kwathunthu, kulimba kwamphamvu kwambiri, biocompatibility yabwino, ndikulimbikitsa kukula kwa maselo. Malingana ndi makulidwe a thupi la mzere, nthawi zambiri amatengeka kwa masiku 8-15, ndipo kuyamwa kumakhala kokhazikika komanso kodalirika, ndipo palibe kusiyana koonekeratu.
