Uyu munsi, twakiriye ikibazo gishimishije giturutse kuri Velentium Medical, ikigo kibaza ku bijyanye n'uburyo dutanga insinga za rukuruzi zihuza n'ibinyabuzima n'insinga za Litz, cyane cyane izikozwe mu ifeza cyangwa zahabu, cyangwa izindi nsinga zihuza n'ibinyabuzima. Iki gisabwa gifitanye isano n'ikoranabuhanga ryo gusharija insinga zidafite insinga ku bikoresho by'ubuvuzi bishobora gushyirwamo.
Tianjin Ruiyuan Electrical Equipment Co., Ltd. yigeze ihura n'ibibazo nk'ibi kandi yahaye abakiriya ibisubizo byiza. Laboratwari ya Ruiyuan yakoze kandi ubushakashatsi bukurikira kuri zahabu, ifeza, n'umuringa nk'ibikoresho bishobora guterwa mu mubiri:
Mu bikoresho by’ubuvuzi bishobora gushyirwamo, ubushobozi bwo guhuza ibikoresho bushingiye ku mikorere yabyo n’ingingo z’umubiri w’umuntu, harimo ibintu nko kurwanya ingese, ubushobozi bw’ubudahangarwa bw’umubiri, n’uburozi bw’umubiri. Muri rusange zahabu (Au) na feza (Ag) bifatwa nk’ibishobora guhuza neza, mu gihe umuringa (Cu) udashobora guhuza neza, kubera impamvu zikurikira:
1. Kuba zahabu ihura n'ibindi (Biocompatibility of Gold)
Ubudakora neza mu by'imiti: Zahabu ni icyuma cyiza kidakora ogisijeni cyangwa ngo cyange mu bidukikije kandi ntigisohora ioni nyinshi mu mubiri.
Ubudahangarwa buke bw'umubiri: Ibara rya zahabu ntirikunze gutera ububyimbirwe cyangwa kwangwa kw'ubudahangarwa bw'umubiri, bigatuma rikoreshwa igihe kirekire mu gutera.
2. Kuba ifeza ihuza ibintu byombi (Ag)
Imiterere y’imiti irwanya bagiteri: Iyoni z’ifeza (Ag⁺) zifite ingaruka za antibiyotike mu buryo bwagutse, bityo zikoreshwa cyane mu byuma bishyirwa mu mubiri by’igihe gito (nk’udupira twa catheter n’udupfundikizo tw’ibisebe).
Gusohora ibintu mu buryo bugenzurwa: Nubwo feza isohora ioni nke, imiterere yayo ikwiye (nk'iy'ifeza ipfukanywe) ishobora kugabanya uburozi, ikagira ingaruka ku mikorobe idateye ingaruka mbi ku turemangingo tw'umuntu.
Uburozi bushobora kubaho: Ingano nyinshi ya iyoni z'ifeza ishobora gutera uburozi bwa cytotoxicity, bityo ni ngombwa kugenzura neza ingano n'umuvuduko w'isohoka ry'ibinyabutabire.
3. Kuba Umuringa uhuza ibintu byombi (Cu)
Uburyo bwinshi bwo gukora imiti: Umuringa uroroha mu mubiri mu buryo bworoshye (nk'uko urema Cu²⁺), kandi iyoni z'umuringa zirekurwa zizatera ingaruka mbi ku miterere y'uturemangingo, bigatera kwangirika kw'uturemangingo, kuvunika kwa ADN, no guhindagurika kwa poroteyine.
Ingaruka zo kubyimbirwa: Iyoni z'umuringa zishobora gukora ubudahangarwa bw'umubiri, bigatera ububyimbirwe budakira cyangwa fibrosis y'ingingo.
Uburozi bw'ubwonko: Kurundanya cyane kw'umuringa (nk'indwara ya Wilson) bishobora kwangiza umwijima n'imitsi, bityo ntibikwiriye gushyirwamo igihe kirekire.
Ikoreshwa ridasanzwe: Imiterere ya mikorobe yo kurwanya udukoko ituma ikoreshwa mu bikoresho by’ubuvuzi by’igihe gito (nk’ibisigazwa by’ubuso birwanya udukoko), ariko ingano y’isohoka ryayo igomba kugenzurwa neza.
Incamake y'ingenzi
| Ibiranga | Zahabu(cyangwa seAU) | Ifeza (Ag) | Umuringa (Cu) |
| Ubudahangarwa bw'inkongi | Ikomeye cyane (idafite imbaraga) | Hagati (Irekurwa buhoro rya Ag+) | Intege nke (Gusohora byoroshye Cu²+) |
| Ubudahangarwa bw'umubiri butera imbere | Hafi nta na kimwe | Igihe gito (Igihe gigenzurwa) | Ifite ububabare bwinshi (butuma umuntu agira ububabare bwinshi) |
| Uburozi bwa Ctotoxicity | Nta na kimwe | Hagati-hejuru (Biterwa n'ubwinshi bw'ibipimo) | Hejuru |
| Imikoreshereze y'ingenzi | Electrode/prothese zishyirwa mu mwanya wazo igihe kirekire | Implants z'igihe gito zirwanya bagiteri | Bikunze kubaho gake (Bisaba ubuvuzi bwihariye) |
Umwanzuro
Zahabu na feza ni byo bikundwa cyane mu bikoresho byo kwa muganga bishyirwamo imiti bitewe nuko bidashobora kwangirika cyane kandi bikaba bishobora kugenzurwa mu buryo bw’ibinyabuzima, mu gihe imikorere y’imiti n’uburozi bw’umuringa bigabanya ikoreshwa ryabyo mu bikoresho byo kwa muganga bishyirwamo imiti igihe kirekire. Ariko, binyuze mu guhindura ubuso (nk’ibumba rya okiside cyangwa ivangavanga), ingano y’imiti irwanya bagiteri y’umuringa ishobora no gukoreshwa ku rugero ruto, ariko umutekano ugomba gusuzumwa neza.
