Abstract

The invention relates to the technical field of medical instruments, and provides a self-anchored prostate hanging-type urethral stent, a visible release catheter and a use method. The self-anchored stent comprises a supporting line; barbs are arranged on the supporting line; the tail of the supporting line is provided with a gasket; the gasket is used for distracting prostate tissue to expand the urethra; the supporting line is a non-absorbable suture line; a first barb is made of metal and used for being interlocked with a puncture needle; and the barbs play a role of a self-anchored fixing stent. By means of the technical scheme, the defects of the prior art in treatment of prostatic hyperplasia: the cost of generally adopted surgical treatment is high, bleeding and tissue losses can be caused, and the male sexual function is affected, are solved. While existing urethral stent interventional therapy has the problems that the treatment effect is poor, recurrent calculous obstruction is easy to occur, the stent is easy to displace and fail, and difficult to take out after failure and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a self-anchored prostate suspension urethral stent, a visible release catheter and a method of use. Background technique [0002] Prostatic hyperplasia is a common disease in elderly men. The incidence rate increases year by year with age, and the incidence rate can reach 80% at the age of 80. The dysuria and complications caused by it seriously affect the quality of life of elderly men. Even need to wear catheter for a long time or cause renal failure. At present, the methods for the treatment of BPH mainly include drug therapy, surgical operation, and urethral stent interventional therapy. The surgical method is transurethral resection of the prostate, which inevitably involves bleeding and the loss of the prostate gland, which will affect the sexual function of the patient: 1, the amount of semen is severely reduced or even absent; 2, retrograde ejaculation 3. Erecti...
