[0002] Ureteroscopy is a new minimally invasive treatment for urinary stones in the past decade. It uses a very thin, soft ureteroscope and laser equipment through the natural cavity of the human body to crush or even powder the upper urinary tract stones. Larger stones are removed by instruments, and the powdered stones can be discharged through the natural cavity, thus achieving the treatment goal. This is also a typical minimally invasive treatment method.

[0003] Existing flexible ureteroscopes are usually single-channel, and optical fibers, cameras, etc. are inserted into the channel to absorb gravel through the gaps in the channel. The gravel will interfere with the wire harness in the channel, making it impossible to remove the gravel.

[0004] Therefore, how to prevent the gravel from being unable to be removed is a technical problem that urgently needs to be solved in this field. Utility Model Content
