The device utilizes a Thulium fiber laser with a wavelength of 1940nm, aligning exactly with the peak of water absorption (as shown in the figure). Its absorption coefficient is 4.5 times that of 1470nm lasers, 4.3 times that of 2100nm Holmium lasers, and twice that of 2013nm solid-state Thulium lasers. The closer the laser wavelength is to the energy absorption peak, the faster the energy absorption and the shallower the penetration depth (only 0.2mm). The irradiated tissue is rapidly vaporized with extremely minimal thermal damage. This achieves the dual effect of optimal vaporization and precise cutting.
Urinary tract stones contain a significant amount of water. When the laser is applied to the stone, the water rapidly absorbs the energy, causing uniform micro-explosions. This pulverizes the stones into fine dust particles, significantly simplifying post-lithotripsy clearance.
In continuous output mode, the power reaches up to 50W. It is fully adjustable, allowing for effortless soft tissue cutting.
