• Laser lithotripsy
• Improve blood circulation
• Resection of tumor
• Intranasal ethmoidectomy
• Arthroscopic surgery

• Shallow penetration
• Small damage range
• High security
• Good water absorption

At present, there are many different types of laser in clinical application of laser lithotripsy. Considering that the high energy density of the laser is easy to damage the human body, the CTH:YAG laser with the output wavelength of 2.1μm is usually chosen. The working principle of CTH:YAG laser lithotripsy is the photothermal effect produced by the physical absorption of the continuous pulse energy from the laser, which is superior to other lasers in property and safety, and avoiding the disadvantages of the traditional form of lithotripsy. Its main advantages are: using the flexible nature of the fiber to cooperate with the use of flexible nephroscope, and the stone removal efficiency is very high. In addition,except the lithotripsy, CTH:YAG laser can also be used to treat local soft tissue lesions, at the same time its thermal radiation has the antibacterial effect.
