Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

First embodiment

Referring to fig. 1-2 in combination, in a first embodiment of the present invention, a removable ureteral stent for convenient use includes: the spiral pipe comprises a sleeve pipe 1, a first spiral pipe 2 and a second spiral pipe 3, wherein the first spiral pipe 2 and the second spiral pipe 3 are respectively arranged at two ends of the sleeve pipe 1, and the sleeve pipe 1, the first spiral pipe 2 and the second spiral pipe 3 are of an integrated structure; the urination mechanism is arranged in the sleeve 1 and comprises a sliding block 5, the sliding block 5 is arranged in the sleeve 1, a supporting plate 6 is fixedly arranged in the sleeve 1, a spring 7 is fixedly arranged at the top of the supporting plate 6, and the top of the spring 7 is fixedly connected with the sliding block 5.

The sleeve pipe 1 with a plurality of feed liquor holes 4 have been seted up on the first spiral pipe 2, urine or other hydrops can enter into in the sleeve pipe 1 through a plurality of feed liquor holes 4.

The sliding block 5 is connected with the inner wall of the sleeve 1 in a sliding and sealing mode.
