Ureteral stent

Abstract

The invention discloses a ureteral stent, and relates to the technical field of medical instruments, the ureteral stent comprises: a first tube body having a first end and a second end opposite to each other; the second pipe body is provided with a third end and a fourth end which are opposite to each other, and the first end of the first pipe body and the third end of the second pipe body are arranged in a sleeving manner; the first position of the wire body is connected with the first pipe body, the second position of the wire body is connected with the second pipe body, at least part of the wire body between the first position and the second position is embedded in the first pipe body or the second pipe body, and the first pipe body and the second pipe body can move in the direction away from each other; and the length of at least part of the wire body embedded in the first pipe body or the second pipe body pulled out of the first pipe body or the second pipe body is equal to the moving distance of the first pipe body and the second pipe body in the direction away from each other. The ureteral stent can solve the problem that the ureteral stent cannot be adjusted more accurately in the length direction.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ureteral stent. Background technique [0002] The ureters are tube-like passages in the body that carry urine from the kidneys to the bladder. Ureteral stents are used to facilitate the drainage of urine from the kidney to the bladder in patients with ureteral obstruction or injury, or to protect the integrity of the ureter during various surgical manipulations. In addition, a ureteral stent is also required in most ureteral or renal pelvis procedures. A conventional ureteral stent is a hollow catheter-like device with a length of about 30 cm that can be installed in the ureter, and its two ends can be J-shaped, so that it can reside in the kidney and bladder respectively. [0003] The currently commercially available ureteral stents with J-shaped ends are divided into one model at intervals of 2 cm in longitudinal length, but it is difficult to meet the differences i...
