Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the ureteral irrigation device comprises a pressurization hollow needle 1, wherein the pressurization hollow needle 1 comprises a piston rod 11 and a sleeve 12 with two through ends, a liquid guide head 2 is fixed at one end of the sleeve 12 through threads, and the flow speed of irrigation liquid passing through the liquid guide head 2 is increased through the arrangement of the pressurization hollow needle 1, so that pressurization is realized;

the liquid guide head 2 comprises a water inlet pipe 3, a water outlet pipe 4 and a flushing pipe 5, the water inlet pipe 3 and the water outlet pipe 4 are both provided with a one-way valve 6, the flushing pipe 5 is provided with a stop valve 7, the flushing liquid is guided by opening and closing the one-way valve 6, and whether the flushing liquid passes through the flushing pipe 5 is controlled by the stop valve;

the flushing pipe 5 is connected with an extension pipe 8, one end of the extension pipe 8, which is far away from the flushing pipe 5, is provided with a flow regulating valve 9, and the size of a port of a liquid discharging end of the extension pipe 8 is regulated through the flow regulating valve 9, so that the flushing pressure is regulated;
