Nheyo yeLaser mukurapa PLDD
Percutaneous Laser Disc Decompression (PLDD) inzira isinganyanyi kukuvadza inoshandiswa kurapa mavanga emuchiuno kana emuromo wechibereko. Nheyo yekushandisa simba relaser muPLDD inotenderera kudzorwa kwekupisa uye kupiswa kwenucleus pulposus—nzvimbo yakapfava, ine gelatinous ye intervertebral disc.
Nheyo Dzekutanga dzeKushandisa Laser mu PLDD:
● Kuendeswa Kwesimba Rakananga:
Fiber yakatetepa ye optical inopinzwa nepaganda (nepaganda) mu herniated disc ichitungamirirwa nemifananidzo (kazhinji fluoroscopy kana CT). Kana yaiswa mukati me nucleus pulposus, laser energy inoendeswa kunzvimbo yakakanganiswa.
● Mhedzisiro yePhotothermal:
Laser (inowanzo shandisa marefu emvura akaita se 980nm diode kana kuti Nd:YAG lasers) inogadzira kupisa kana ikatorwa nemvura nemapuroteni ari munucleus pulposus. Izvi zvinokonzera:
● Kupisa kwemhepo huwandu hwemvura mu tissue ye disc.
● Kuvhara kwemafuta uye kudzima kwehunhu hwemuviri collagen nemamwe mapuroteni.
● Kuderedzwa kwekumanikidzwa kwemukati medhisiki nekuda kwekubviswa kwenyama uye kutetepa kweganda.
● Kuderedza Vhoriyamu yeDisiki:
Nekubvisa huwandu hushoma (kazhinji 1-2 mL) hwenucleus pulposus, kumanikidzwa kwese mukati mediski kunoderera. Izvi zvinobatsira kudzosera chikamu che herniated, nokudaro zvichideredza kudzvanywa kwemidzi yetsinga dziri pedyo uye kuderedza marwadzo.
● Husingapindi uye Hunodzivirira Maumbirwo emuviri:
Kusiyana ne open discectomy, PLDD haidi kubviswa kwemapfupa kana kukanganiswa kwakakosha kwenyama dzakapoteredza. Annulus fibrosus (chikamu chekunze che disc) inoramba yakadaro, ichichengetedza kugadzikana kwemusana.
● Kukurudzirwa Kwekuporesa Kwemuviri:
Humwe humbowo hunoratidza kuti kukuvara kwekupisa kunodzorwa kunogona kukurudzira kuporeswa kwenzvimbo uye kuderedza zvinhu zvinokonzera kuzvimba (semuenzaniso, ma cytokines akadai seTNF-α neIL-6) anokonzera marwadzo asingaperi.
Zvakanakira Zvikuru:
● Kurapwa kwekunze kwechipatara
● Nguva pfupi yekupora
● Pangozi shoma yekutapukirwa kana mavanga
● Inogona kudzokororwa kana zvichidikanwa
Muchidimbu, laser iri muPLDD inoshanda ne kubvisa uye kuderedza tissue yediski kuburikidza nesimba rekupisa kwezuva, nokudaro zvichideredza kumanikidzwa kwemukati mediscular uye kutsamwa kwemidzi yetsinga uye kusanyanya kukuvara kwezvivako zvakakomberedza.
