Calculus removing device for urinary surgery

The invention relates to the technical field of urinary surgery, in particular to a urinary surgery calculus removing device which comprises a flexible lens, a holmium laser optical fiber, a flushing assembly and the like. The holmium laser optical fiber penetrates through the soft lens channel in a sliding mode, a flushing assembly is arranged on the soft lens and comprises a hard tube, an on-off valve, a liquid storage tank and a miniature water pump, the hard tube is communicated with the soft lens, and the on-off valve used for controlling connection and disconnection of an inner cavity of the hard tube is arranged on the hard tube. The top of the on-off valve is connected with a disc used for driving the on-off valve to rotate so as to achieve on-off control over an inner cavity of the hard pipe, and the hard pipe is communicated with the liquid storage box. Cleaning liquid in the liquid storage tank is pumped into the hard pipe through the micro water pump, conveyed to the soft lens channel through the
