Partial-rapid-dissolution anti-reflux ureter support

Abstract

The invention discloses a partial-rapid-dissolution anti-reflux ureter support. The partial-rapid-dissolution anti-reflux ureter support comprises a support tube body, and the support tube body is sequentially divided into a renal-pelvis-section tube body, a ureter upper-section tube body, a ureter lower-section tube body, a ureter bladder-wall-section tube body and a bladder section tube body from top to bottom, wherein the renal-pelvis-section tube body, the ureter upper-section tube body, the ureter lower-section tube body, the ureter bladder-wall-section tube body and the bladder section tube body are integrally connected; the ureter lower-section tube body, the ureter bladder-wall-section tube body and the bladder section tube body are dissoluble tube bodies, a bifilar thin silk thread penetrates through the dissoluble tube bodies, the upper end of the bifilar thin silk thread is connected with the ureter upper-section tube body, the lower portion of the bifilar thin silk thread is joined into a single-stranded thin silk thread, and a silica gel ring located in the bladder section tube body is connected to the lower end of the bifilar thin silk thread. The dual-J tube reflux problem is solved, particularly, for patients needing to reserve the ureter support for a long time, the occurrence probability of upper urinary tract infection can be reduced, hydronephrosis exacerbation caused by ureter reflux is avoided, patient pains are reduced, and the life quality is improved.

Description

technical field [0001] The invention relates to a partially rapidly dissolving anti-reflux ureteral stent. Background technique [0002] Ureteral stents are widely used in urology, suitable for renal and ureteral calculus surgery and before extracorporeal shock wave lithotripsy; patients with external ureteral compression that need to be relieved of obstruction; suitable for kidney transplantation, ureteral stenosis and dilatation, and other treatments, some patients need long-term Lien. At present, the ends of both sides of the ureteral stent are curled into double "pigtails", such as figure 1 As shown, the front and rear ends of the stent form a "J" shape, also known as a double "J" tube. The ends are bent in opposite directions to form a circle, one end is located in the kidney door, and the other end is located in the bladder. The stent body is placed in the lumen of the ureter. After implanted in the ureter, it can drain urine and prevent ureteral stricture and adhe...
