Te Whakaiti Kōpae Reiti Kiri (PLDD)kua whakatūria hei huarahi iti rawa te whakaekenga ki te pokanga tuwhera tikanga mō te rongoā i ngā kōpae intervertebral herniated. Ko te kaupapa matua o te PLDD ko te whakaurunga o tētahi muka whatu motuhake ki roto i te pūtake kōpae, ā, muri iho ka tukuna te kaha laser hei tango i tētahi wāhanga iti o te pūtake pulposus (NP). Ka hangaia e tēnei mimiti he kōhao intradiscal whakahaeretia, ka whakaiti i te pēhanga ā-roto, ā, muri iho ka whakamama i te pēhanga ki ngā hanganga io tata. I roto i ngā pūnaha laser rerekē e wātea ana, kua whakaatuhia e ngā laser diode e tukuna ana i te 980nm me te 1470nm te whai huatanga motuhake nā ō rātou kōtaha mimiti ahurei i roto i ngā kiko koiora.
Ko te roangaru 980nm e whakaatu ana i te taurite o te mimiti i roto i te wai me te hemoglobin. Mā tēnei āhuatanga ka taea te whakapūmau i ngā oko toto iti i roto i te kōpae me te tango pai i te NP i te wā kotahi. Heoi, ka mimitihia te pūngao 980nm e ngā kiko kāore i te whainga, e hiahia ana kia tino tupato kia kore ai e pakaru te pereti pito o te wheua i te werawera.
He rerekē, ko te roanga ngaru 1470nm e tata ana ki te tihi o te mimiti wai. Nō reira, ko tōna kaha ka mimitihia tata katoatia e te NP waikura, ka whakarite kia tino herea te pānga wera. He nui ake te whai huatanga o te tangohanga o te taiaho 1470nm—tata ki te 20 ki te 30 ngā wā nui atu i tērā o ngā pūnaha 1064nm Nd:YAG tawhito—e āhei ai te wā whakaaturanga poto ake me te whakaiti i te horapa wera āpiti ki te annulus fibrosus me ngā io e karapoti ana. Ko ngā roanga ngaru e rua ka tukuna mā te muka whatu, e ārahi ana i te hihi i roto i te tauira pupuhi whakamua. He mea nui te hoahoa muka whatu mō te PLDD, nā te mea ka taea e te taote pokanga te aro tika ki te wāhanga pokapū o te NP me te whakaiti i te mōrearea o te pokanga o te pakitara kōpae.
Ko ngā painga haumanu o te huarahi roa-ngaru rua 980nm/1470nm ko te whakahekenga tonu o te pēhanga i roto i te kōpae, te whakaora tere i muri i te pokanga, me te tiaki i ngā wāhanga nekehanga tuaiwi. Ko te tikanga ka ripoatahia e ngā tūroro he whakaora nui o te mamae radicular i roto i ngā haora 24 ki te 48. He iti te auau raruraru ina arahina ngā tikanga e te fluoroscopy, ā, ka whakawhāitihia ki ngā hernia kōpae kua mau.
Hei whakamutunga, ko te mahi tahi i waenga i te roangaru 980nm (te toto totoka) me te roangaru 1470nm (te mimiti wai teitei) e tino pai ai te hangarau taiaho diode mō te PLDD. Ka tukuna e tēnei tikanga he maimoatanga haumaru, hototahi ki waho o te whare mō te mate kōpae lumbar tohumate, ka whakaitihia te rahinga o te NP me te kore e whakararuraru i te pou tuaiwi. Me whakahaere tonu ētahi atu rangahau tirohanga whakamua hei arotau i ngā tawhā pūngao me ngā whakatairite putanga mō te wā roa.
