[0002] The wavelength of thulium-doped fiber laser is around two microns, which is just at a high absorption peak of water. Since most of human tissue is water, this type of fiber laser has broad application prospects in medicine. It has been used for the removal, vaporization and coagulation of soft tissues, and can also be used for the crushing and removal of stones, and has received good feedback from users.

[0003] Laser treatment has become one of the mainstream lithotripsy methods. The mainstream lithotripsy methods in domestic hospitals include extracorporeal shock wave lithotripsy, pneumatic ballistic lithotripsy and holmium laser lithotripsy. Laser lithotripsy has obvious advantages because it can cause little damage to surrounding normal tissues, has mild postoperative reactions, fast wound healing, small scars, and good hemostasis. It can be used in conjunction with various endoscopes or puncture needles to reach the stone through the ureter to achieve minimally invasive or non-invasive surgery. However, laser treatment also has certain defects. Due to its wide wavelength range, its penetration depth into human tissues is very shallow, and the treatment effect is poor.
