Embodiment 1

[0025] Such as figure 1 As shown, the present invention provides a magnetically controlled urethral valve including a valve body 10 assembly and a magnetic assembly 70 matched with the valve body 10 assembly. The valve body 10 assembly includes a valve body 10 and a valve core 20 matched with the valve body 10 , The valve body 10 placed in the urethra 50 is matched with the valve core 20, and the switch of storing and releasing urine is realized through the opening and closing of the valve core 20 relative to the valve body 10.

[0026] The valve core 20 can slide relative to the valve body 10, the valve core 20 includes a urinary catheter, and the valve core 20 is a cylindrical elongated structure. The urinary catheterization part includes a catheterization cavity and a catheterization hole 22. The catheterization cavity is a cavity structure provided by the valve core 20, and the catheterization hole 22 is a hole provided by the valve core 20 and connected to the cavity structur...

Embodiment 2

[0036] This embodiment is similar to Embodiment 1, except that, in this embodiment, the first anchoring mechanism 12 and the second anchoring mechanism 13 are made of shape memory alloy. The shape memory alloy has a shape memory effect, and the first anchor The fixing mechanism 12 is formed by at least one slat-like structure to form a multi-claw structure, and the second anchoring mechanism 13 is configured as a net-like structure. After the urethra 50 valve is implanted in the urethra 50, the first anchoring mechanism 12 and the second anchoring mechanism 13 return to their design shapes, restricting the displacement of the urethra 50 valve after being implanted in the urethra 50, and facilitating the implantation of the urethra 50 valve into the urethra 50.

Abstract

The invention belongs to the field of medical devices, and particularly relates to a magnetically controlled urethra valve. The magnetically controlled urethra valve comprises a valve body assembly and a magnetic assembly which cooperates with the valve body assembly; the valve body assembly comprises a valve body which is placed in a urethra and a valve element which cooperates with the valve body; the valve element can slide relative to the valve body; the valve element is provided with a urine guiding portion used for discharging urine; the urine guiding portion discharges the urine; an elastic piece is arranged between the valve element and the valve body; by the elastic piece, the valve element resets relative to the valve body; the valve element comprises a traction portion which cooperates with the magnetic assembly, and the traction portion drags the valve element to slide relative to the valve body under the effect of the magnetic assembly. Urine storage and discharge of a bladder are controlled by an internal structure, injury of the urethra is avoided, meanwhile, external magnetically controlled urine discharge is carried out, and thermal injury to tissues of the urethrais avoided.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and specifically relates to a magnetically controlled urethral valve. Background technique [0002] The urinary dysfunction of the bladder caused by damage to the central or peripheral nerves is a special disease called neurogenic bladder. Since the genitourinary system depends on the central and peripheral nervous systems to coordinate the storage and excretion function of the bladder, the dysfunction of the genitourinary system after spinal cord injury has a serious impact on the quality of life of patients, often accompanied by renal failure, urinary incontinence, stones, Complications such as urinary retention. [0003] The existing treatment programs for neurogenic urinary incontinence mainly include: intermittent urinary catheterization, drug therapy, neuromodulation, urinary tract reconstruction surgery, bioengineering treatment, with the purpose of protecting the upper urinary tract, preventing...
