Umgaqo weLaser kuNyango lwe-PLDD
Ukususwa kweDiski yeLaser yePercutaneous (PLDD) yinkqubo engaphantsi kakhulu esetyenziselwa ukunyanga ii-herniations zediski ye-lumbar okanye ye-cervical. Umgaqo wokusebenzisa amandla elaser kwi-PLDD ujikeleza ukukhutshwa kobushushu okulawulwayo kunye nokuphefumla kwe-nucleus pulposus—iziko elithambileyo nelithambileyo lediski ye-intervertebral.
Imigaqo Ephambili Yokusetyenziswa Kwelaser kwi I-PLDD:
● Ukunikezelwa kwamandla okujoliswe kuko:
Ifayibha ebhityileyo ye-optical ifakwa nge-percutaneously (ngolusu) kwi-herniated disc phantsi kwesikhokelo somfanekiso (ngesiqhelo yi-fluoroscopy okanye i-CT). Nje ukuba ibekwe ngaphakathi kwi-nucleus pulposus, amandla e-laser athunyelwa ngqo kwindawo echaphazelekayo.
● Isiphumo se-Photothermal:
I-laser (edla ngokusebenzisa ubude be-wavelengths efana I-diode ye-980nm okanye ii-laser ze-Nd:YAG) zivelisa ubushushu xa zifunxwa ngamanzi kunye neeproteni kwi-nucleus pulposus. Oku kubangela:
● Ukufutha umphunga umxholo wamanzi kwi-disc tissue.
● Ukuxinana kobushushu kunye nokuguquguquka i-collagen kunye nezinye iiproteni.
● Ukunciphisa uxinzelelo lwangaphakathi kwediski ngenxa yokususwa kwezicubu kunye nokuncitshiswa kwazo.
● Ukunciphisa ivolumu yeDiski:
Ngokususa umthamo omncinci (ngesiqhelo i-1-2 mL) ye-nucleus pulposus, uxinzelelo olupheleleyo ngaphakathi kwidiski luyancitshiswa. Oku kunceda ukubuyisela inxenye ye-herniated, ngaloo ndlela kunciphisa uxinzelelo kwiingcambu zemithambo-luvo ezikufutshane kwaye kunciphise intlungu.
● I-Anatomy Engangeni Kancinci kwaye Ayigcini Kakuhle:
Ngokungafaniyo ne-open discectomy, i-PLDD ayifuni ukususwa kwethambo okanye ukuphazamiseka okukhulu kwezicubu ezingqongileyo. I-annulus fibrosus (umaleko wediski yangaphandle) ihlala injalo, igcina umqolo uzinzile.
● Ukuvuselela Ukuphilisa Ngokwebhayoloji:
Ubungqina obuthile bubonisa ukuba ukwenzakala okulawulwayo kobushushu kunokukhuthaza iimpendulo zokuphiliswa kwendawo kwaye kunciphise izinto ezibangela ukudumba (umz., ii-cytokines ezifana ne-TNF-α kunye ne-IL-6) ezinegalelo kwintlungu engapheliyo.
Iingenelo eziphambili:
● Inkqubo yokunyanga ngaphandle kwesibhedlele
● Ixesha elifutshane lokubuyela kwimeko yesiqhelo
● Umngcipheko omncinci wokosuleleka okanye amanxeba
● Ingaphindaphindwa ukuba kuyimfuneko
Ngamafutshane, i-laser kwi-PLDD isebenza nge ukukhupha ngokuchanekileyo nokunciphisa izicubu zediski ngamandla e-photothermal, ngaloo ndlela kunciphisa uxinzelelo lwangaphakathi kwe-discal kunye nokurhawuzelelwa kweengcambu zemithambo-luvo ngaphandle kokwenzakala okukhulu kwizakhiwo ezingqongileyo.
