• Tissue Sensor technology is an intelligent feature designed to maximize surgical safety during lithotripsy

   

  It continuously monitors laser-tissue interaction in real time, helping prevent accidental energy delivery to non-target soft tissues. This technology ensures that energy is applied only where it’s needed, protecting surrounding structures and minimizing complications.

• Thulium Fiber Laser (TFL) lithotripsy technology

  Thulium Fiber Laser (TFL) represents the most advanced innovation in urinary stone management, combining superior efficiency, precision, and safety.

  TFL offers multiple fragmentation strategies tailored to stone size and surgical goals:

  • Fragmentation mode breaks stones into fragments smaller than 3 mm, facilitating easy removal.

  • Dusting mode pulverizes stones into fine particles less than 1 mm, allowing for natural elimination.

  • Fine Dusting mode further reduces stone debris to ultrafine dust smaller than 0.25 mm, minimizing the need for manual extraction.

   

  With minimal retropulsion, stones remain stable during energy delivery, improving fragmentation efficiency and procedural control. TFL operates at a lower temperature compared to traditional lasers, significantly reducing thermal injury to surrounding tissues and enhancing overall procedural safety.

  Reduced fiber burn-back extends the lifespan of the laser fiber, lowering procedural costs and ensuring consistent energy delivery throughout the surgery.

• UltraPulse fragmentation mode

   

  UltraPulse is a breakthrough laser mode optimized for efficient and safe stone fragmentation.
  It works by creating thermal stress waves inside the stone, causing it to crack and disintegrate without excessive mechanical force.

  
  Compared to standard pulse modes, UltraPulse provides higher fragmentation efficiency and greater safety, minimizing the risk of tissue damage during lithotripsy procedures.

   

• Urolase Vision System (UVS) acts as a real-time surgical assistant.

  It integrates directly with Urolase+, Premium, and MAX laser devices to provide on-screen monitoring and visualization during surgery. UVS enhances surgeon awareness, improves procedural control, and supports safer, faster, and more precise treatments — especially during complex lithotripsy and soft tissue surgeries.

• Thulium Fiber Laser (TFL) soft tissue surgery technology

   

  Thulium Fiber Laser (TFL) technology is transforming soft tissue surgery by offering unmatched precision, efficiency, and surgical control.

  TFL ensures superior hemostasis, providing excellent bleeding control during both vaporization and enucleation procedures.
  This results in a cleaner surgical field, improved visibility, and safer operations.

  With a minimal thermal spread of only 0.6 mm — compared to 1–3 mm with conventional Ho:YAG lasers — TFL significantly reduces collateral tissue damage, preserving healthy surrounding structures and promoting faster patient recovery.

  Unlike pulsed laser systems, TFL delivers continuous-wave energy, allowing for smoother, more controlled tissue cutting.
  This continuous energy flow enhances precision during dissection and minimizes surgical trauma.

  TFL enables 20% shorter operation times, even in challenging cases involving large prostates (>80 mL), improving surgical workflow, reducing anesthesia exposure, and enhancing overall clinical efficiency.

  Through these advantages, TFL redefines standards in soft tissue surgery, delivering better clinical outcomes and a more predictable surgical experience for both surgeons and patients.
