Absorbable suture
Absorbable sutures tau muab faib ntxiv rau hauv: plab, tshuaj lom neeg ua ke (PGA), thiab ntshiab collagen sutures nyob ntawm cov khoom thiab qib ntawm kev nqus.
1. Yaj plab: Nws yog tsim los ntawm cov tsiaj noj qab nyob zoo yaj thiab tshis txoj hnyuv thiab muaj cov khoom collagen.Yog li ntawd, nws tsis yog yuav tsum tau tshem tawm cov xov tom qab suturing.Kev kho mob plab kab: kab plab kab thiab chrome plab kab, ob leeg tuaj yeem nqus tau.Lub sijhawm ntev npaum li cas rau kev nqus yog nyob ntawm qhov tuab ntawm lub plab thiab qhov mob ntawm cov ntaub so ntswg.Nws feem ntau absorbed rau 6 mus rau 20 hnub, tab sis tus neeg sib txawv cuam tshuam rau cov txheej txheem nqus los yog nqus tau.Tam sim no, lub plab yog ua los ntawm cov khoom pov tseg aseptic, uas yooj yim siv.
(1) Ordinary plab: ib qho yooj yim absorbable suture ua los ntawm cov ntaub so ntswg submucosal ntawm lub plab los yog bovine txoj hnyuv.Kev nqus sai sai, tab sis cov ntaub so ntswg teb me ntsis rau lub plab.Nws feem ntau yog siv los kho cov hlab ntsha sai dua lossis cov ntaub so ntswg subcutaneous kom ligature cov hlab ntsha thiab cov kab mob suture.Nws yog feem ntau siv rau hauv cov txheej mucosal xws li lub tsev menyuam thiab zais zis.
(2) Chrome plab: Cov plab no yog tsim los ntawm kev kho chromic acid, uas tuaj yeem ua rau cov ntaub so ntswg nqus tau qeeb, thiab nws ua rau mob tsawg dua li cov plab hnyuv.Feem ntau siv rau gynecological thiab urinary phais, nws yog ib tug suture feem ntau siv nyob rau hauv lub raum thiab ureteral phais, vim hais tias cov txhob lo lo ntxhuav yuav txhawb kev tsim ntawm pob zeb.Soak hauv dej ntsev thaum siv, ncaj tom qab softening, txhawm rau pab txhawb kev ua haujlwm.
2, chemical synthesis kab (PGA, PGLA, PLA): cov khoom siv polymer linear ua los ntawm cov cuab yeej siv tshuaj niaj hnub no, los ntawm cov txheej txheem ntawm kev kos duab, txheej thiab lwm yam txheej txheem, feem ntau absorbed nyob rau hauv 60-90 hnub, haum stability.Yog hais tias nws yog qhov ua rau ntawm cov txheej txheem ntau lawm, muaj lwm cov tshuaj tsis muaj degradable, qhov nqus tsis tiav.
3, ntshiab ntuj collagen suture: muab los ntawm cov tsiaj tshwj xeeb raccoon leeg, siab ntuj collagen ntsiab lus, cov txheej txheem ntau lawm yam tsis muaj kev koom tes ntawm cov tshuaj, muaj cov yam ntxwv ntawm collagen;rau tam sim no muaj tseeb plaub tiam ntawm sutures.Nws muaj tag nrho nqus, siab tensile zog, zoo biocompatibility, thiab txhawb kev loj hlob ntawm tes.Raws li lub thickness ntawm kab lub cev, nws yog feem ntau absorbed rau 8-15 hnub, thiab qhov nqus tau ruaj khov thiab txhim khu kev qha, thiab tsis muaj qhov sib txawv ntawm tus kheej.
