AI Technical Summary

Technical Problem

The prior art has problems such as high surgical cost, affecting sexual function, poor interventional treatment effect of urethral stents, prone to re-obstruction of stones, translocation of stents, failure and difficulty in removing after failure.

Method used

Self-anchored prostate suspension type urethral stent and visual release catheter are adopted. Metal barbs are provided at the front end of the support line for self-anchoring, and gaskets are provided at the end of the support line to open the prostate. Combined with the opening and release device of the visual release catheter, the effective placement and fixation of the urethral stent is achieved.

Benefits of technology

Through self-anchored fixation and continuous expansion of the prostate tissue, the effective expansion of the urethra is achieved, the problems of urethra stenosis and dysuria are solved, the complications of surgery are avoided, and the stability and long-term effectiveness of the urethra stent are improved.

Abstract

The present invention relates to the technical field of medical devices, and proposes a self-anchoring prostate suspension urethral stent and a visual release catheter and a method of use. The self-anchoring stent includes a support line, a barb is provided on the support line, a gasket is provided at the tail of the support line, the gasket is used to open the prostate tissue and expand the urethra, the support line is a non-absorbable suture line, and the first barb is a metal barb, which is used to fit with the puncture needle, and the barb plays the role of a self-anchoring fixed stent. Through the above technical scheme, the defects of the prior art in the treatment of prostate hyperplasia are creatively solved: the surgical treatment commonly used at present is costly, and can cause bleeding, tissue loss, and affect male sexual function. However, the existing urethral stent interventional treatment has the problems of poor treatment effect, easy stone re-obstruction, easy displacement and failure of the stent, and difficulty in removal after failure.
