Kubaga
Surgical Sutures ningirakamaro mu gufunga ibikomere, bifite ubushobozi bwo gukoresha imbaraga nini kuruta ibifatika no kwihutisha inzira yo gukira bisanzwe. Hariho ibikoresho byinshi byo kubaga byafashwe ingamba kubwiyi ntego - nka plastiki yangirika kandi idashobora kwangirika, poroteyine zikomoka ku binyabuzima, hamwe n’ibyuma - ariko imikorere yabyo yagarutsweho no gukomera kwabo. Ibikoresho bisanzwe byo kudoda birashobora gutera kubura amahwemo, gutwikwa no kubangamira gukira, mubindi bibazo nyuma yo kubagwa.
Mu rwego rwo gukemura iki kibazo, abashakashatsi bo muri Montreal bakoze ubuhanga bushya bwa gel sheathed (TGS) bwo kubaga bwatewe na tendon ya muntu.
Ibisekuru bizaza-ibisekuru birimo kunyerera, ariko bigoye cyane ibahasha ya gel, yigana imiterere yimyenda yoroshye. Mugushira ikizamini gikomeye cyo kubaga (TGS) kubagwa, abashakashatsi basanze ubuso bwa geli butavanze bugabanya ibyangiritse mubisanzwe biterwa na suture gakondo.
Ubudodo busanzwe bwo kubaga bumaze ibinyejana byinshi kandi bikoreshwa mugukomeretsa hamwe kugeza inzira yo gukira irangiye. Ariko ntibiri kure cyane yo gusana imyenda. Fibre ikaze irashobora gukata no kwangiza ingirangingo zoroshye, biganisha ku kutamererwa neza no nyuma yo kubagwa.
Abashakashatsi bavuga ko kimwe mu bibazo by’imyenda isanzwe ari ukudahuza hagati yimyenda yacu yoroshye hamwe nuburemere bwimyenda idahwitse. Kaminuza ya McGill hamwe nitsinda rya INRS Énergie Matériaux Télécommunications Centre yubushakashatsi yegereye iki kibazo batezimbere ikoranabuhanga rishya ryigana ubukanishi bwimitsi.
Ahumekewe na Tendons Yabantu
Kugira ngo iki kibazo gikemuke, itsinda ryateje imbere ikoranabuhanga rishya ryigana ubukanishi bw'imitsi. Ati: “Igishushanyo cyacu cyahumetswe n'umubiri w'umuntu, icyatsi cya endotenon, kikaba gikomeye kandi gikomeye kubera imiterere yacyo ya kabiri.
Ihuza fibre ya kolagen mu gihe umuyoboro wa elastin uyishimangira. "
Icyatsi cya endotenon kigira ubuso butanyerera kugirango kigabanye guterana hamwe nuduce dukikije kandi gitanga ibikoresho byo gusana ingirangingo mu gikomere cya tendon, kigizwe na selile nimiyoboro yamaraso hamwe nubwikorezi rusange no gusana imitsi.
Abashakashatsi bavuga ko imashini zikomeye zo kubaga (TGS) zo kubaga zishobora gushyirwaho kugira ngo zitange imiti yihariye ishingiye ku byo umurwayi akeneye.
Ibisekuruza bizakurikiraho
Amashusho ya kaminuza ya McGill arimo suture izwi cyane yubucuruzi ikozwe mu ibahasha ya geli yigana iki cyatsi. Gele ikarishye (TGS) suture yo kubaga irashobora guhimbwa kugeza kuri 15cm z'uburebure kandi irashobora gukonjeshwa-yumishijwe kugirango ibike igihe kirekire.
Abashakashatsi bakoresheje mbere uruhu rwa pcine hanyuma bakerekana urugero rwimbeba, abashakashatsi berekanye ko zishobora gukoreshwa mubudozi busanzwe bwo kubaga no gupfundika kandi bigira akamaro mugufunga ibikomere bidateye kwandura.
Gele ikaze (TGS) yo kubaga suture - mubindi bisa na endotenon sheath - irashobora kandi gushushanywa kugirango itange ibikomere byihariye.
Kuvura ibikomere byihariye
Abashakashatsi berekanye iri hame bapakira suture hamwe na antibacterial compound, pH sensing microparticles, ibiyobyabwenge na nanoparticles ya fluorescent yo kurwanya kwandura, gukurikirana ibitanda bikomeretsa, gutanga ibiyobyabwenge no gukoresha bioimaging.
Ati: “Iri koranabuhanga ritanga igikoresho kinini cyo gucunga neza ibikomere. Twizera ko ishobora gukoreshwa mu gutanga ibiyobyabwenge, gukumira indwara, ndetse no gukurikirana ibikomere bifata amashusho hafi ya infragre, ”ibi bikaba byavuzwe na Li wo mu ishami rishinzwe imashini.
Li, akaba n'umuyobozi ushinzwe ubushakashatsi muri Kanada mu binyabuzima no mu buzima bwa Musculoskeletal, agira ati: "Ubushobozi bwo gukurikirana ibikomere byaho no guhindura ingamba zo kuvura kugira ngo bikire neza ni icyerekezo gishimishije cyo gushakisha."
