Stent replacement system suitable for urinary retention and urinary incontinence

Abstract

The invention relates to a stent replacement system suitable for urinary retention and urinary incontinence. The stent replacement system comprises a stent system and a control system. The stent system comprises a cylindrical urethral stent with an anti-falling lug and a valve. The anti-falling lug is matched with the expansibility of the urethral stent, so that the stability of the device can beguaranteed. The valve can control the opening and closing of the urethra. The control system comprises a power supply module, a central control module, a pressure sensing module, a signal transmissionmodule and a power module and is used for realizing intelligent control. The power module comprises a transmission shaft and a spiral blade; opening and closing of the valve can be achieved in cooperation with a blocking rod on a fixed valve seat and a blocking piece on a movable valve plug. The spiral blade can form a vortex to assist urination. The system has the advantages that the urethra canbe expanded, urination can be assisted, operable intelligent control over opening and closing of the urethra is achieved, the stability is good, and the system can be placed for a long time so as toeffectively cope with urinary retention and urinary incontinence.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bracket replacement system suitable for urinary retention and urinary incontinence. Background technique [0002] Benign prostatic hyperplasia is one of the most common diseases of the male urinary system. A large number of elderly people are facing problems such as acute urinary retention, chronic urinary retention, and overflow urinary incontinence. For the elderly with complex medical diseases, transurethral enucleation of the prostate is no longer the first choice. The alternative therapy is long-term indwelling urinary catheter and regular replacement. The risk of urinary tract infection is high, and the quality of life of patients is extremely poor. [0003] For urination, urinary incontinence is also an important clinical problem, and long-term urinary incontinence can even affect mental and psychological health. Common causes of urinary incontinence include tru...

Problems solved by technology

This patent document can avoid the phenomenon that it cannot effectively support the prostatic urethra caused by the displacement of the bladder neck, which affects the phenomenon of spontaneous urination, and can improve the passage of urine, reduce the irritation symptoms to the trigone of the bladder, and improve comfort ; But it is mainly through the setting of the urination opening, so that the number of urination holes is increased compared with the existing balloon-shaped stent, so as to maintain the smooth flow of urination, but it does not have the function of solving urinary retention and urinary incontinence caused by abnormal urination function

[0006] Chinese patent document: CN108969164A, discloses a prostate stent, including: an elastic support, driven to switch between a compressed state and a stretched state, the The elastic support member in the stretched state applies a biasing force to the inner wall of the prostatic urethra to expand the prostatic urethra; the anti-off piece, the first end of the anti-off piece is connected to the elastic support piece, the second end can be Retractably supported on the inner wall of the prostatic urethra, the second end presses the inner wall of the prostatic urethra to elastically deform to prevent the elastic support from protruding from the direction of the bladder; this patent document solves the problem of The prostate stents in the prior art cannot prevent it from being easily affected by external forces and thus shift toward the bladder side of the large opening of the prostatic urethra, or even fall into the bladder, causing the stent to completely deviate from the preset position, which cannot solve the problem of prostatic hypertrophy, or even fall into the bladder. The bladder brings painful problems to patients, but first of all, it does not have the function of solving urinary retention and urinary incontinence caused by abnormal urination function. The expansion of the urethra can gradually break through the hyperplasia of the prostate according to medical needs; and the handle part runs through the entire urethra, which is easily polluted by urine and easily causes cross-infection, and does not have intelligent control means
