Uruhare rw'uburebure bw'umuraba wa 980nm na 1470nm mu gukuraho icyuma gishyushya disiki ya laser (PLDD)

Gukuraho Disiki ya Laser Ikoresha Uruhu (PLDD)yigaragaje nk'uburyo bworoshye bwo kubaga mu buryo busanzwe bwo kuvura disiki zo mu bwoko bwa herniated intervertebral discs. Ihame ry'ibanze rya PLDD rikubiyemo gushyira fibre yihariye y'urumuri mu gice cy'urumuri, hagakurikiraho gutanga ingufu za laser kugira ngo habeho ingano nto ya nucleus pulposus (NP). Ubu buryo bwo guhumeka butuma habaho umwobo ugenzurwa hagati y'urumuri, bigabanura umuvuduko w'imbere hanyuma bigakuraho gukandamizwa kw'imitsi yo mu bwonko iri hafi aho. Muri sisitemu zitandukanye za laser ziboneka, diode lasers zisohora kuri 980nm na 1470nm zagaragaje imikorere yihariye bitewe n'imiterere yazo yihariye yo kwinjiza mu ngingo z'umubiri.

Ubunini bw'umurambararo bwa 980nm bugaragaza uburyo bwo kwinjiza neza mu mazi na hemoglobine. Ubu buryo butuma imiyoboro mito y'amaraso ifatana icyarimwe ndetse no gukura neza ubushyuhe bwa NP. Ariko, ingufu za 980nm zinjira mu gice cy'uturemangingo tutari mu gice cy'ingenzi, ibyo bikaba bisaba ubuhanga buhanitse kugira ngo hirindwe kwangirika k'ubushyuhe ku gice cy'imbere cy'umuyoboro w'amaraso.

Mu buryo bunyuranye, uburebure bwa 1470nm buri hafi y’aho amazi anyura. Kubera iyo mpamvu, ingufu zayo zinjira hafi ya zose muri NP ifite amazi, bigatuma habaho ubushyuhe buto cyane. Ubushobozi bwo gukuraho ubushyuhe bwa laser ya 1470nm buri hejuru cyane—hafi inshuro 20 kugeza kuri 30 ugereranyije n’uburyo bwa kera bwa 1064nm Nd:YAG—bituma igihe cyo kwigaragaza kiba gito kandi bigagabanya ikwirakwira ry’ubushyuhe kuri annulus fibrosus no ku mitsi iyikikije. Ubunini bwa uburebure bwombi bukunze gutangwa binyuze muri Fibre Optical, iyobora urumuri mu buryo bwo gukurura imbere. Igishushanyo cya Fibre Optical ni ingenzi kuri PLDD, kuko yemerera umuganga kubaga kwibanda neza ku gice cyo hagati cya NP mu gihe bigabanya ibyago byo gutobora urukuta rwa disiki.

Ibyiza byo kwivuza by’uburyo bwa 980nm/1470nm bwo gukora uburebure bw’umurambararo burimo kugabanya umuvuduko ako kanya muri disiki, gukira vuba nyuma yo kubagwa, no kubungabunga ibice by’umugongo. Abarwayi bakunze kuvuga ko ububabare bukabije bugabanuka mu masaha 24 kugeza kuri 48. Igipimo cy’ingorane kiba gito iyo uburyo buyobowe na fluoroscopy kandi bugashyirwa gusa ku gupima disiki.

Muri make, ubufatanye hagati y’uburebure bwa 980nm (gufungana kw’imitsi) n’uburebure bwa 1470nm (kwinjizwamo amazi menshi) bituma ikoranabuhanga rya diode laser rikwiriye cyane PLDD. Ubu buryo butanga uburyo bwizewe kandi bujyanye n’indwara y’uruhu rw’umugongo ifite ibimenyetso, bugabanya neza ingano ya NP nta guhungabanya urwego rw’umugongo. Hari izindi nyigo ziteganijwe kugira ngo hakorwe neza ibipimo by’ingufu no kugereranya umusaruro mu gihe kirekire.
