Problems solved by technology

All existing ureteral stents must be removed through invasive operations, usually by cystoscopy. Although this type of cystoscopy is not considered a major operation, the patient will suffer, especially for male patients. Can’t even tolerate ureteral stent pullout, and the pullout will cause varying degrees of damage to the urinary tract tissue, causing infection and edema, and some cases often require emergency treatment

Abstract

The invention discloses a ureteral stent, which comprises a body, a degradable tube and a traction line, wherein the body has a tubular structure; one end of the body is bent into an arc, and the other end of the body is connected with the degradable tube; the other end of the body and the degradable tube are bent into an arc; the bending direction of the other end of the body and the degradable tube is opposite to the bending direction of one end of the body; the traction line is wound and fixed in the tube wall of the degradable tube; and one end of the traction line is fixed with the end part of the body. Compared with the prior art, the ureteral stent can automatically release the traction line after being implanted into a body for a period of time, and the ureteral stent can be pulled out by dragging the traction line in vitro, so that cystoscope removal can be avoided, the pain of the patient due to cystoscope operation is relieved and the injury to the patient during cystoscope removal is reduced.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a ureteral stent. Background technique [0002] A ureteral stent is a long, thin tube that runs from the kidney to the bladder. When the ureter is blocked, a ureteral stent supports the ureter so that urine can drain from the kidney to the bladder. A urologist will place a stent in the ureter in many cases, such as when stones, scar stenosis, tumors, etc. cause obstruction. Ureteral surgery (including ureteroscopy, lithotripsy, and open ureteral surgery) routinely requires the placement of ureteral stents, and renal pelvis surgery (such as pyelolithotomy, renal pelvis plasticity, percutaneous nephrolithotomy, etc.) also requires routine placement of ureteral stents . [0003] Ureteral stents are widely used in urological surgery, and currently there is no ureteral stent that can be permanently placed in the body. All existing ureteral stents must be removed ...
