Iriburiro ryimyanya ndangagitsina

Inda yo munda nigikoresho cyubuvuzi, mubisanzwe imiterere yigituba ikozwe mubyuma cyangwa plastike, ikoreshwa mugukemura inzitizi zo munda ziterwa na stenose yo munda cyangwa gufunga. Inda zo munda zirashobora guterwa munsi ya endoskopi cyangwa binyuze mu mwobo muto mu ruhu, kandi gutera intanga birashobora kwagura agace kagufi k'amara kugira ngo bigarure ububobere bwo mu nda n'imikorere. Gutera intanga zo munda birashobora gukoreshwa mu kuvura indwara nyinshi zo munda, nk'ikibyimba cyo mu mara, indwara zifata umura, kanseri yandura, n'ibindi. Ubu buryo bwo kuvura bufite ibyiza byo kudatera, byihuse, kandi bigira ingaruka nziza, bishobora kuzamura ireme rya ubuzima bw'abarwayi no kugabanya ububabare bwabo n'ibimenyetso bitameze neza.

Inda yo munda ni ubwoko bushya bwibikoresho byubuvuzi, kandi iterambere ryayo rishobora guhera mu mpera za za 70 na za 1980. Inda yambere yo munda yari ikozwe muri plastiki kandi yakoreshwaga cyane mu kuvura inzitizi zo mu gifu zo hejuru ziterwa no gukomeretsa nabi nka kanseri yo mu nda na kanseri y'ibihaha. Hamwe niterambere ryikoranabuhanga ryubuvuzi, ibyuma byakoreshejwe cyane mukuvura inzitizi zo munda.

Mu 1991, Ikigo gishinzwe ibiryo n'ibiyobyabwenge (FDA) cyo muri Amerika cyemeje icyuma cya mbere cyo kuvura indwara ya biliary no gufatwa. Kuva icyo gihe, gukoresha ibyuma byerekana ibyuma byagiye byiyongera buhoro buhoro kugira ngo bivure indwara zitandukanye zo mu gifu no gufatwa, nka kanseri yo mu nda, kanseri yo mu gifu, kanseri yo mu nda, kanseri ya biliary, kanseri ya kanseri yandura na kanseri y'urura runini.

Mu myaka yashize, hamwe niterambere ryiterambere rya tekinoroji yubuvuzi, igishushanyo n’ibikoresho byo mu nda nabyo byarushijeho kunozwa. Igishushanyo mbonera cya kijyambere kigezweho kirahuza cyane namahame ya biomehanike, ashobora guhuza neza nibiranga physiologique yibiranga amara kandi bigakemura ibibazo bigoye byindwara. Muri icyo gihe, gutoranya ibikoresho nabyo biratandukanye, harimo ibyuma bitagira umwanda, cobalt chromium alloy, titanium yera, na nikel titanium. Ibi bikoresho bishya ntabwo bifite imiterere yubukanishi gusa, ahubwo biranarwanya ruswa kandi birwanya biocompatable, bishobora kugabanya kubaho kwimyitwarire mibi nibibazo nyuma yo guterwa stent.

Nuburyo bwihuse kandi bunoze bwo kuvura, stent yakoreshejwe cyane kandi igira uruhare runini mukuvura amara yo mu nda no gufatwa. Hamwe niterambere ridahwema no kunoza ikoranabuhanga, byizerwa ko amara yo munda azaba afite uburyo bwagutse bwo gukoresha ejo hazaza.
