Surgical Sutures
Surgical Sutures yog qhov tseem ceeb rau kev kaw qhov txhab, muaj peev xwm ua kom muaj zog ntau dua li cov ntaub nplaum nplaum thiab ua kom cov txheej txheem kho kom zoo. Muaj ntau cov ntaub ntawv phais mob uas tau raug coj los siv rau lub hom phiaj no - xws li cov yas degradable thiab nondegradable, cov protein tau los ntawm cov roj ntsha, thiab cov hlau - tab sis lawv qhov kev ua tau zoo tau raug txwv los ntawm lawv cov tawv nqaij. Cov ntaub ntawv suture pa tuaj yeem ua rau tsis xis nyob, mob thiab kho tsis zoo, nrog rau lwm yam teeb meem tom qab phais.
Hauv kev sib zog los daws qhov teeb meem no, cov kws tshawb fawb los ntawm Montreal tau tsim cov txheej txheem tawv tawv tawv (TGS) phais phais kev tshoov siab los ntawm tib neeg cov leeg.
Cov tom ntej no sutures muaj ib tug nplua, tseem tawv gel hnab ntawv, ua raws li cov qauv ntawm cov ntaub so ntswg mos. Hauv kev muab cov tawv gel sheathed (TGS) phais sutures rau qhov kev sim, cov kws tshawb fawb pom tias qhov ze li ntawm qhov tsis muaj kev sib txhuam gel tau txo qhov kev puas tsuaj feem ntau tshwm sim los ntawm cov tsoos sutures.
Cov kev phais kev phais tau nyob ib puag ncig rau ntau pua xyoo thiab tau siv los tuav cov qhov txhab ua ke kom txog thaum cov txheej txheem kho kom tiav. Tab sis lawv nyob deb ntawm qhov zoo tagnrho rau kev kho cov ntaub so ntswg. Cov fibers ntxhib tuaj yeem hlais thiab ua rau cov ntaub so ntswg puas lawm, ua rau tsis xis nyob thiab muaj teeb meem tom qab kev phais.
Raws li cov kws tshawb fawb, ib feem ntawm qhov teeb meem nrog cov pa sutures yog qhov tsis sib haum xeeb ntawm peb cov ntaub so ntswg thiab lub rigidity ntawm sutures uas rub tawm tsam cov ntaub so ntswg. McGill University thiab INRS Énergie Matériaux Télécommunications Research Center pab pawg tau ntsib cov teeb meem no los ntawm kev tsim cov thev naus laus zis tshiab uas ua rau cov neeg kho tshuab ntawm cov leeg.
Kev tshoov siab los ntawm Tib Neeg Tendons
Txhawm rau daws qhov teeb meem, pab pawg tau tsim cov thev naus laus zis tshiab uas ua rau cov neeg kho tshuab ntawm cov leeg. "Peb tus qauv tsim tau txais kev tshoov siab los ntawm tib neeg lub cev, endotenon sheath, uas yog ob qho tib si tawv thiab muaj zog vim nws cov qauv kev sib txuas ob.
Nws khi collagen fibers ua ke thaum nws cov elastin network ntxiv dag zog rau nws, "hais tias tus thawj coj sau Zhenwei Ma, PhD cov tub ntxhais kawm nyob rau hauv kev saib xyuas ntawm Assistant xibfwb Jianyu Li ntawm McGill University.
Lub endotenon sheath tsim ib tug nplua nto los txo cov kev sib txhuam nrog cov ntaub so ntswg nyob ib puag ncig thiab tseem muab cov ntaub ntawv kho cov ntaub so ntswg nyob rau hauv ib tug mob leeg, muaj cov hlwb thiab cov hlab ntsha thiab loj thauj thiab kho cov leeg.
Cov tawv gel sheathed (TGS) phais phais tuaj yeem tsim kho los muab cov tshuaj kho tus kheej raws li tus neeg mob xav tau, hais cov kws tshawb fawb.
Tom ntej no tsab xov xwm Suture Materials
McGill University sutures muaj cov kev lag luam nrov braided suture nyob rau hauv ib lub hnab ntawv gel ua raws li cov ntaub qhwv no. Cov tawv gel sheathed (TGS) phais sutures tuaj yeem tsim txog li 15cm ntev thiab tuaj yeem khov-qhuav rau lub sijhawm ntev.
Siv thawj daim tawv nqaij porcine thiab tom qab ntawd tus qauv nas, cov kws tshawb fawb tau pom tias lawv tuaj yeem siv rau cov qauv kev phais thiab cov pob qij txha thiab muaj txiaj ntsig zoo rau lub qhov txhab kaw yam tsis muaj kab mob.
Cov tawv gel sheathed (TGS) phais sutures - nyob rau hauv lwm qhov sib npaug nrog endotenon sheaths - tseem tuaj yeem tsim los muab kev kho mob ntawm tus kheej.
Kev kho mob ntawm tus kheej
Cov kws tshawb fawb tau pom cov ntsiab lus no los ntawm kev thauj cov sutures nrog cov tshuaj tua kab mob, pH sensing microparticles, tshuaj thiab fluorescent nanoparticles rau kev tiv thaiv kab mob, tshuaj xyuas lub txaj txaj, tshuaj xa thiab siv bioimaging.
"Lub tshuab no muab ntau yam cuab yeej rau kev tswj qhov txhab zoo. Peb ntseeg tias nws tuaj yeem siv los xa cov tshuaj, tiv thaiv kev kis kab mob, lossis tseem saib xyuas qhov txhab nrog cov duab ze ze-infrared, "Li ntawm Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm Tshuab.
Li hais tias "Lub peev xwm los saib xyuas qhov txhab hauv zos thiab kho cov tswv yim kho kom zoo dua yog qhov kev xav zoo siab los tshawb nrhiav," hais tias Li, uas yog tus thawj coj tshawb fawb Canada hauv Biomaterials thiab Musculoskeletal Health.
