Prostate urethral stent with recovery structure

Abstract

The invention relates to the field of urinary system medical instruments, in particular to a prostate urethral stent with a recovery structure, the stent is woven into a spring-shaped structure by metal wires, the stent is composed of a long straight section, an expansion section and the recovery structure, and the recovery structure is located at the tail end of the stent. According to the recovery structure, a recovery part can be observed more easily during recovery of the stent, clamping is more convenient during operation, a doctor can position and clamp the recovery part of the stent more easily during recovery of the stent, the recovery time of the stent is greatly shortened, the surgical risk is greatly reduced, the recovery efficiency of the stent is improved, and the burden of the doctor and a patient is reduced.

Description

technical field [0001] The invention relates to the field of urinary system medical devices, in particular to a prostatic urethral stent.
