Ukususwa Kwe-Percutaneous Laser Disc (PLDD)isizisungule njengendlela ehlukile engavamile yokuhlinzwa okuvamile okuvulayo yokwelapha ama-disc e-intervertebral aqukethwe yi-herniated. Isimiso esiyisisekelo se-PLDD sihilela ukufakwa kwe-fiber optical ekhethekile ku-nucleus ye-disc, kulandelwe ukulethwa kwamandla e-laser ukuze kususwe umthamo omncane we-nucleus pulposus (NP). Lokhu kuhwamuka kudala umgodi olawulwayo we-intradiscal, kunciphisa ingcindezi yangaphakathi futhi kamuva kunciphise ukucindezelwa kwezakhiwo ze-neural eziseduze. Phakathi kwezinhlelo ezahlukene ze-laser ezitholakalayo, ama-diode lasers akhipha ku-980nm kanye no-1470nm abonise ukusebenza kahle okukhethekile ngenxa yamaphrofayili awo okumunca ahlukile ezicutshini zebhayoloji.
Ubude be-wavelength obungu-980nm bubonisa i-coefficient elinganiselayo yokumuncwa emanzini kanye ne-hemoglobin. Lesi sici sivumela ukuhlangana kwemithambo emincane yangaphakathi kwe-discal kanye nokususwa okusebenzayo kokushisa kwe-NP. Kodwa-ke, amandla angu-980nm amuncwa kancane yizicubu ezingezona eziqondiwe, okudinga ubuchwepheshe obucophelelayo ukuze kugwenywe ukulimala kokushisa kwe-cartilaginous endplate.
Ngokuphambene nalokho, ubude be-wavelength obungu-1470nm buseduze nenani eliphakeme lokumuncwa kwamanzi. Ngenxa yalokho, amandla ayo amuncwa cishe yi-NP enamanzi kuphela, okuqinisekisa umphumela wokushisa olinganiselwe kakhulu. Ukusebenza kahle kwe-ablation kwe-laser engu-1470nm kuphakeme kakhulu—cishe izikhathi ezingu-20 kuya kwezingu-30 zikhulu kunezinhlelo ze-1064nm Nd:YAG ezidala—okuvumela izikhathi zokuchayeka ezimfushane kanye nokuncipha kokusabalala kokushisa okuhlangene ku-annulus fibrosus kanye nemizwa ezungezile. Womabili ama-wavelength avame ukulethwa nge-Optical Fiber, eqondisa umsebe ngendlela yokudubula phambili. Ukwakheka kwe-Optical Fiber kubalulekile ku-PLDD, njengoba kuvumela udokotela ohlinzayo ukuthi aqondise ngqo ingxenye ephakathi ye-NP ngenkathi enciphisa ingozi yokubhoboza udonga lwediski.
Izinzuzo zezokwelapha zendlela ye-980nm/1470nm dual-wavelength zifaka phakathi ukunciphisa ingcindezi ngokushesha ngaphakathi kwediski, ukululama okusheshayo ngemva kokuhlinzwa, kanye nokulondolozwa kwezingxenye zokunyakaza komgogodla. Iziguli zivame ukubika ukukhululeka okukhulu kobuhlungu obukhulu phakathi kwamahora angama-24 kuya kwangu-48. Izinga lezinkinga liphansi uma izinqubo ziqondiswa yi-fluoroscopy futhi zikhawulelwe ekuhlungeni amadiski aqukethwe.
Ekuphetheni, ukusebenzisana phakathi kobude be-wavelength obungu-980nm (ukujiya kwemithambo yegazi) kanye nobude be-wavelength obungu-1470nm (ukumuncwa kwamanzi amaningi) kwenza ubuchwepheshe be-diode laser bufaneleke kakhulu kwi-PLDD. Le ndlela inikeza ukwelashwa okuphephile, okuhambisana nesiguli ngaphandle kwesiguli sesifo se-lumbar disc esinezimpawu, okunciphisa ngempumelelo umthamo we-NP ngaphandle kokuphazamisa ikholomu yomgogodla. Izifundo ezengeziwe ezilindelekile ziyafuneka ukuze kuthuthukiswe imingcele yamandla kanye nokuqhathaniswa kwemiphumela yesikhathi eside.
