The water injection groove 2 adopts a special structure in which one corner of the water discharge platform is low and the surrounding areas are high, which is conducive to the water flowing downward while the bubbles will not flow down. The water eventually flows downward from the bottom of the water pipe 3 along the natural drop. At this time, the medical staff can install the constant temperature ureteroscope, cystoscope and arthroscope that need to be cleaned at the end of the water pipe 3.
