Medical Holmium Laser Apparatus

 

The treatment machine can produce a high-power density laser beam which of wavelength is 2100nm, and through the fiber transmission system to target tissue for treatment.

It is mainly used in the endoscopic treatment of urology lithiasis.

working principle：

The products are used by Yttrium Aluminum Garnet (YAG) as the matrix material, doped pulse solid lasers which made by laser crystal of chromium (Cr), thulium (Tm), holmium (Ho) ions, produce λ=2100nm laser, and this is just at the peak range of water absorption. When using for urinary calculi bombardment, the laser energy is absorbed high-effectively by stone surface and internal water, then instantly micro-expansion of the vaporization have burst, that crush all kinds of composition of urinary calculi immediately. The efficient absorption of water for holmium laser makes the penetration depth in tissue less than 0.4 mm, which can guarantee high precision and unique surgical clotting effect.
