Abstract

The invention relates to a urinary stent. The urinary system stent comprises a stent body and a cleaning robot, and the cleaning robot is slidably connected with the support body and can reciprocate along the surface of the support body to physically clean the surface of the support body. According to the urinary stent, by means of surface physical cleaning operation formed in the process that the cleaning robot reciprocates along the stent body, calculi formed on the surface of the stent body can be effectively removed, blockage of the calculi to the stent body is avoided, and it is guaranteed that the urinary system stent can effectively and stably work for a long time in the body of a postoperative patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a urological bracket. Background technique [0002] With the development of medical device technology, the implantation of urinary stents has become an important clinical treatment for kidney stones, ureteral stones, ureteral stenosis, urethral stenosis, and prostate stenosis. According to the treatment of different diseases, Urinary system stents can be further divided into prostate stents, ureteral stents, urethral stents, etc. [0003] However, according to clinical data, no matter what kind of urological stent implantation treatment is performed, implantation failure due to postoperative calculus formation on the surface of the stent accounts for about 50% of clinical postoperative complications. In response to this problem, in the current clinical treatment, postoperative complications are mainly controlled by taking anti-stone drugs, urinating a large number of pat...
