Description

In-vitro laser lithotripsy efficiency detection device Technical Field The utility model relates to the technical field of laser lithotripsy, in particular to an in-vitro laser lithotripsy efficiency detection device. Background In the laser lithotripsy process, laser optical fibers are led into the body through an endoscope (such as a ureteroscope and a percutaneous nephroscope) to directly act on the calculus, and the calculus can be crushed without open operation. This minimally invasive approach significantly reduces trauma, bleeding risk, and post-operative recovery time of traditional surgery, and patients can generally resume daily activities in a short period of time. For example, thulium laser lithotripsy combined with soft-mirror techniques can treat kidney stones greater than 2 cm. Laser lithotripsy efficiency directly affects the stability of the procedure time and energy release. The high-efficiency lithotripsy can shorten the operation time and reduce the heat loss and cold risk of the laser to surrounding tissues. For example, the tissue penetration depth of holmium laser is only 0.4mm, and if lithotripsy is inefficient, repeated procedures may increase the probability of ureteral perforation or kidney injury.
