Embodiment Construction

[0031] In order to have a clearer understanding of the technical features, objectives and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, it should be understood that "front", "rear", "up", "down", "left", "right", "vertical", "horizontal", "vertical", "horizontal", The orientation or positional relationship indicated by "top", "bottom", "inner", "outer", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is constructed and operated in a specific orientation. It is only for the convenience of describing the technical solution, rather than indicating that the pointed device or element must have a specific orientation, so it cannot be understood as a limitation of the present invention.

[0032] It should also be noted that, unless otherwise clearly specified and limited, terms such as “ins...

Abstract

The invention relates to the field of stent assemblies for the ejaculatory ducts, and provides a stent assembly for the ejaculatory ducts. The stent assembly comprises two tubular stents, and each tubular stent comprises a combination section and a separation section; a tail section of each separation section is elastically bent into a bent shape in the natural state; the combination sections of the two tubular stents are provided with combination structures, so that the two combination sections are combined side by side into an integral body; after side-by-side combination, the radial size ofthe two combined combination sections is equal to that of the single separation section. For the human boy with two seminal vesicles, according to the stent assembly for the ejaculatory ducts, the tubular stents can smoothly enter the ejaculatory ducts and the seminal vesicles through cooperation between the tubular stents and guide wires, the combination sections of the two tubular stents are combined side by side into the integral body through the combination structures, after combination, the two tubular stents are in a shape that one of the ejaculatory ducts is divided into two duct parts, and the two duct parts respectively enter the two seminal vesicles, and the effect of supporting the ejaculatory ducts is achieved; the ejaculatory ducts are kept unobstructed, and therefore the problem of ejaculatory duct obstruction is solved.

Description

Technical field [0001] The invention relates to the field of ejaculatory duct stent components. Background technique [0002] The technique of urethral seminal vesicles is widely used in clinical practice. In addition to refractory hemospermia, some other distal seminal diseases such as severe ejaculatory duct obstruction or azoospermia and seminal cysts can be treated by this method. . [0003] Ejaculatory duct obstruction is a defect in sperm drainage that occurs in the ejaculatory duct at the far end of the seminal tract. It is one of the causes of male infertility caused by obstructive factors, but it is one of the few male infertility that can be cured by surgery. The most common cause of intractable hematospermia may be the ejaculatory duct obstruction caused by cysts in the ejaculatory duct area or inflammatory stenosis of the ejaculatory duct opening. Inflammation and obstruction can promote the formation of stones in the seminal tract, and stones can aggravate inflammatio...
