Ukuncitshiswa kweDiski yeLaser yePercutaneous (PLDD)iye yazimisa njengenye indlela engaphantsi kotyando oluqhelekileyo oluvulekileyo lokunyanga iidiski ze-intervertebral eziqulethwe yi-herniated. Umgaqo osisiseko we-PLDD ubandakanya ukufakwa kwefayibha ekhethekileyo ye-optical kwi-nucleus yediski, kulandele ukuhanjiswa kwamandla e-laser ukuze kususwe umthamo omncinci we-nucleus pulposus (NP). Olu hlobo lokuphefumla ludala umgodi olawulwayo we-intradiscal, lunciphisa uxinzelelo lwangaphakathi kwaye emva koko lunciphise uxinzelelo kwizakhiwo ze-neural ezikufutshane. Phakathi kweenkqubo ezahlukeneyo ze-laser ezikhoyo, ii-diode lasers ezikhupha kwi-980nm kunye ne-1470nm zibonakalise ukusebenza kakuhle ngenxa yeeprofayili zazo zokufunxa ezizodwa kwizicubu zebhayoloji.
Ubude be-980nm bubonisa i-coefficient elinganiselayo yokufunxa emanzini nakwi-hemoglobin. Le propati ivumela ukujiya kwemithambo emincinci ngaphakathi kwe-discal ngaxeshanye kunye nokususwa okusebenzayo kobushushu be-NP. Nangona kunjalo, amandla e-980nm afunxwa kancinci zizicubu ezingezizo ezijoliswe kuzo, nto leyo efuna ubuchule obucokisekileyo ukuze kuthintelwe umonakalo wobushushu kwi-cartilaginous endplate.
Ngokwahlukileyo koko, ubude be-1470nm busondele kwincopho yokufunxwa kwamanzi. Ngenxa yoko, amandla ayo afunxwa phantse yi-NP emanzi, okuqinisekisa isiphumo sobushushu esilinganiselweyo. Ukusebenza kakuhle kwe-ablation ye-laser ye-1470nm kuphezulu kakhulu—malunga namaxesha angama-20 ukuya kuma-30 amakhulu kuneenkqubo ze-1064nm Nd:YAG ezindala—okuvumela amaxesha amafutshane okuvezwa kunye nokunciphisa ukusasazeka kobushushu obudibeneyo kwi-annulus fibrosus kunye nemithambo-luvo ejikelezileyo. Zombini ubude be-wavelengths zihlala zihanjiswa nge-Optical Fiber, ekhokela umqadi ngendlela yokudubula phambili. Uyilo lwe-Optical Fiber lubalulekile kwi-PLDD, njengoko luvumela ugqirha ukuba ajolise ngokuchanekileyo inxalenye ephakathi ye-NP ngelixa enciphisa umngcipheko wokugqobhoza udonga lwediski.
Iingenelo zonyango zendlela ye-980nm/1470nm dual-wavelength ziquka ukunciphisa uxinzelelo kwangoko kwidiski, ukuchacha ngokukhawuleza emva kotyando, kunye nokugcinwa kwamacandelo okushukuma komgogodla. Izigulana zihlala zixela ukukhululeka okukhulu kwintlungu engapheliyo kwiiyure ezingama-24 ukuya kuma-48. Izinga leengxaki liphantsi xa iinkqubo zikhokelwa yi-fluoroscopy kwaye zilinganiselwe kwi-disc herniations equlethweyo.
Ukuqukumbela, ukusebenzisana phakathi kwe-980nm wavelength (i-vascular coagulation) kunye ne-1470nm wavelength (ukufakwa kwamanzi amaninzi) kwenza iteknoloji ye-diode laser ifaneleke kakhulu kwi-PLDD. Le ndlela inika unyango olukhuselekileyo, oluhambelanayo nolusetyenziswa ngaphandle kwesibhedlele kwisifo se-lumbar disc esineempawu, olunciphisa ngokufanelekileyo umthamo we-NP ngaphandle kokuphazamisa umqolo. Izifundo ezongezelelweyo ezilindelekileyo ziyafuneka ukuze kuphuculwe iiparameter zamandla kunye nothelekiso lweziphumo zexesha elide.
