Kubvisa Kumanikidzwa kweDisiki reLaser rePercutaneous (PLDD)Yakazvigadzira senzira isinganyanyi kukuvadza pane yekuvhiyiwa kwekare kwekurapa ma disc e intervertebral discs ane herniated. Nheyo huru yePLDD inosanganisira kuisa fiber yakasarudzika mu nucleus ye disc, ichiteverwa ne laser energy delivery kuti ibvise huwandu hushoma hwe nucleus pulposus (NP). Kupisa uku kunogadzira intradiscal cavity inodzorwa, ichideredza kumanikidzwa kwemukati uye zvichizoderedza kudzvanywa kwe neural structures dziri pedyo. Pakati pema laser system akasiyana-siyana aripo, diode lasers inoburitsa pa 980nm ne 1470nm yakaratidza kushanda kwayo kwakanyanya nekuda kwema profiles ayo akasiyana ekunyudzwa mumatishu e biological.
Hurefu hwema 980nm hunoratidza mwero wekunyudzwa kweropa mumvura nehemoglobin. Izvi zvinoita kuti midziyo midiki yeropa ikwanise kuvharika panguva imwe chete uye kuti NP ikwanise kupfuudzwa zvakanaka. Zvisinei, simba re980nm rinonyudzwa zvishoma nenyama dzisiri dzechinangwa, izvo zvinoda hunyanzvi hwakanyanya kudzivirira kukuvara kwemafuta emudumbu.
Kusiyana neizvi, urefu hwemafungu e1470nm huri pedyo nepamusoro pekunyudzwa kwemvura. Saka, simba rayo rinonyudzwa neNP ine mvura chete, zvichiita kuti kupisa kuve kwakadzikama. Kushanda zvakanaka kwelaser ye1470nm kwakakwira zvakanyanya—kupfuura ka20 kusvika ku30 kupfuura masisitimu ekare e1064nm Nd:YAG—zvichibvumira nguva pfupi yekuratidzwa uye kupararira kwekupisa kwakaderera kune annulus fibrosus netsinga dzakatenderedza. Mafungu ese ari maviri anowanzo endeswa kuburikidza neOptical Fiber, iyo inotungamira danda nenzira yekupfura mberi. Dhizaini yeOptical Fiber yakakosha kune PLDD, sezvo ichibvumira chiremba wekuvhiya kunyatsonanga chikamu chepakati cheNP uku ichideredza njodzi yekuboora madziro ediski.
Zvakanakira zvekurapa zve 980nm/1470nm dual-wavelength approach zvinosanganisira kuderedza kumanikidzwa kwemuviri nekukurumidza mukati me diski, kupora nekukurumidza mushure mekuvhiyiwa, uye kuchengetedzwa kwezvikamu zvekufamba kwemusana. Varwere vanowanzo taura kuti vanonzwa zororo guru rekurwadziwa kwemusana mukati memaawa makumi maviri nemana kusvika makumi mana nemasere. Mwero wematambudziko ushoma kana nzira dzichitungamirirwa ne fluoroscopy uye dzichingogumira pakubviswa kwema disc.
Mukupedzisa, kubatana pakati pe 980nm wavelength (vascular coagulation) uye 1470nm wavelength (high water absorption) kunoita kuti tekinoroji ye diode laser ive yakakodzera PLDD. Iyi nzira inopa kurapwa kwakachengeteka, kunoenderana nevarwere vanorwara nechirwere che lumbar disc, zvichideredza huwandu hweNP pasina kukanganisa spinal column. Zvimwe zvidzidzo zvinotarisirwa zvinodiwa kuti zviwedzere simba uye kuenzanisa mhedzisiro kwenguva refu.
