Web6 feb. 2024 · Published in BiOS 6 February 2024 Physics The Thulium fiber laser (TFL) is being explored as an alternative to Holmium:YAG laser for lithotripsy. TFL beam profile allows coupling of higher power into smaller fibers than multimode Holmium laser beam, without proximal fiber tip degradation.
WebLaser lithotripsy was introduced in the 1980s. Pulsed dye lasers emit 504 nm ( cyan -colored) light that is delivered to the stone by optical fibers through a scope. … WebThe electrohydraulic lithotripsy (EHL) technique uses a charge generator and a bipolar probe to create a spark to produce a vapor plasma. The vapor plasma becomes a cavitation bubble that oscillates around the tip of the probe, which leads to stone fragmentation by absorption of rebounding shockwaves from the vapor [ 4 ].
