Embedded device for controlling internal urethral orifice of prostate gland and placement method for embedded device

Abstract

The invention relates to an embedded device for controlling an internal urethral orifice of a prostate gland and a placement method for the embedded device. The embedded device comprises a metallic ring and an external remote controller, wherein the metallic ring is circular or quasi-circular, is made from a material with biocompatibility and is provided with the external remote controller so as to control a shape of the metallic ring to be stretched and contracted. The placement method for the embedded device comprises the steps: S1: a doctor places the metallic ring into a urinary tract region of the prostate gland visibly under a synchronous endoscope; S2: the doctor incises a trace shallow flute mark at the urinary tract region of the prostate gland through circular incision and embedsthe metallic ring into the shallow flute mark; S3: the placed region maintains a middle part of the gland and an own direction of the metallic ring; and S4: after a circular metallic ferrule is fixed, the external remote controller can be equipped, extruding towards two lateral lobes is carried out effectively to strut the internal urethral orifice when circular stretching is observed, two circular sides are effectively retracted as required when urination ends up, a ureteral orifice is restored and even in a closed state, and thus, urine is effectively controlled or an abnormal phenomenon ofreverse semen flow is effectively avoided.

Description

technical field

[0001] The invention relates to an embedded device for controlling the internal opening of the prostatic urethra and an insertion method thereof. Background technique

[0002] The prostate is a very important urogenital gland surrounding the neck of the bladder and the internal opening of the urethra in men. The resulting urethral structure of the prostate is very important for men to avoid retrograde ejaculation during urine storage, urination and sexual life. The abnormal function of the prostatic urethra due to prostatic tissue hyperplasia, infection, injury or surgery is becoming more and more common with age, especially becoming one of the most common reasons that trouble the normal function of urination and sexual life in middle-aged and elderly men. Generally speaking, according to different etiology and disease progression, problems of the prostatic urethra will cause lower urinary tract symptoms such as repeated frequent urination, urgency, dysuria, ...
