Intracorporeal Lithotripsy (IL) refers to a procedure for Lithotripsy inside the human body with special instruments, including mechanical, hydroelectrical, ultrasound, laser, and pneumatic Lithotripsy. IL has been a long-standing development over the last 20 years with improvements in urological intraluminal devices and procedures. Although External Shock Wave Lithotripsy (ESWL) has become the first treatment of upper urinary tract stones, for lower urinary tract stones, ureteral incarceration stones, giant kidney stones, etc., stones with difficult ESWL localization or treatment and severe "stone streets" after shock wave lithotripsy, IL is still an indispensable treatment.
At present, in-vivo lithotripsy for stones is performed by positioning the sizes of stones through a perspective technology, but the evaluation of the components, the sizes and the hardness of the stones depends on the clinical experience of doctors, and the doctors judge which pulse energy laser is selected for lithotripsy, so the lithotripsy effect and the lithotripsy time are different from person to person.
In the lithotripsy operation process, the conventional operation is that after a doctor visually observes that a laser probe is at a safe distance from the end of a flexible ureteroscope, a button is started to carry out lithotripsy; however, in the actual operation process, the operation personnel may start the lithotripsy by mistake under the condition that the safe distance is not reached, so that the ureteroscope is damaged or the human body is damaged.
