Description
Holmium:YAG Laser Lithotripsy System
Product Introduction
The Holmium:YAG laser lithotripsy system is a minimally invasive surgical laser device used in urology for fragmentation and removal of urinary tract stones, including kidney stones, ureteral stones, and bladder stones.
It operates at a wavelength of 2100 nm, which is highly absorbed by water in biological tissues, allowing precise and controlled stone fragmentation with minimal penetration depth and reduced risk to surrounding tissue. This system is widely recognized as the gold standard laser technology in modern endourology.
What is Holmium:YAG Laser?
The Holmium:YAG (Ho:YAG) laser is a pulsed solid-state medical laser applied for endoscopic urological procedures, with core characteristics as follows:
- Wavelength: 2100 nm (infrared spectrum)
- High absorption rate by water
- Shallow tissue penetration (~0.3–0.4 mm)
- Dual functions for stone fragmentation and dusting
- Compatible with both flexible and rigid endoscopes
Key Advantages
High-Efficiency Stone Fragmentation
Laser energy is delivered via optical fibers to crush stones into tiny fragments or dust, facilitating natural excretion by patients.
Minimal Thermal Injury
The shallow tissue penetration depth greatly lowers thermal damage to adjacent normal tissues and improves surgical safety.
Versatile Clinical Modes
Supports multiple mature lithotripsy operation modes:
- Fragmentation mode (high energy, low frequency)
- Dusting mode (low energy, high frequency)
- Popcorning technique for residual stone clearance
Full Endoscopic Compatibility
Matches mainstream endoscopic equipment:
- Flexible ureteroscopes (fURS)
- Rigid ureteroscopes
- PCNL (Percutaneous Nephrolithotomy) systems
Global Clinical Gold Standard
Accepted as the universal preferred intracorporeal lithotripsy laser by urology departments worldwide.
