Background

Currently, most bladder stone lithotripsy adopts holmium laser lithotripsy under a cystoscope or improved holmium laser lithotripsy under a prostate resectoscope, which can use holmium laser lithotripsy but cannot use air pressure ballistic lithotripsy; the method for breaking stone by using the air pressure trajectory can only be replaced by a ureteroscope, and the stone breaking of larger stones cannot be carried out. In addition, most of cystoscopic holmium laser lithotripsy adopted for cystolith lithotripsy is carried out without circulating water washing, the visual field is not clear in the operation, and particularly when the prostate and bladder bleed, the definition is poor, and the calculus is easy to miss; on the one hand, the improved holmium laser lithotripsy under the prostate resectoscope is thicker, and the urethra is easy to be damaged due to No. F26; on the other hand, the air pressure trajectory lithotripsy can not be used under the resectoscope, the probe rod entering the resectoscope body needs to be bent, the probe rod is easy to rub with the resectoscope body, and the lithotripsy energy is reduced, so the air pressure trajectory lithotripsy under the improved resectoscope is rarely adopted clinically. Most hospitals only have one lithotripsy tool, the cystoscope lithotripsy has more defects, and only holmium laser can be used under the improved resectoscope. Still there are many units to have holmium laser instrument equipment, only the atmospheric pressure trajectory, and the broken stone of atmospheric pressure trajectory can only be replaced with ureteroscope again, and the operation is inconvenient, and the field of vision is more unclear.
