Problems solved by technology

[0006] At present, there is no special embolus for hydrosalpinx embolism for assisted reproduction, and the tubal embolus for sterilization is not suitable for hydrosalpinx embolism for assisted reproduction. At present, platinum microcoils for embolizing blood vessels are used as fallopian tubes The embolism of hydrops is not only expensive in materials, but also requires X-ray irradiation to perform embolism, which is not conducive to women's fertility. At the same time, because the design of embolism blood vessels is not completely suitable for the structure of fallopian tubes, sometimes the embolism falls off, etc. occur

Embodiment Construction

[0024] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0025] Such as Figure 1~3 As shown, the fallopian tube embolus 1 of this embodiment is a helical tube made of nickel-titanium alloy wire. The inside of the helical tube forms a pipeline structure, and a section of filling material 11 for closing the helical tube is arranged inside the helical tube. The filling material 11 of this embodiment, such as polyacrylamide gel, is arranged at the end B of the spiral tube.

[0026] The diameters of the helical units of the helical tube in this embodiment are the same. The length of the spiral tube is 10-30 mm, and the diameter is 0.5-3 mm. In the natural state, the spira...

Abstract

The invention discloses an oviduct plug and a pushing device used in cooperation with the oviduct plug. The plug is a spiral tube which is formed by winding a linear memory metal wire. A pipeline structure is formed inside the spiral tube, and at least one filling material section is arranged inside the spiral tube and used for closing the spiral tube. The oviduct plug is made of specific structure materials such as nickel-titanium alloy materials, so that the oviduct plug is kept bent, and is a structure more suitable for plugging and fixing inside the oviduct; in this way, the ideal effect of oviduct embolism formed manually is achieved.

Description

technical field [0001] The invention relates to an auxiliary device for treating hydrosalpinx, in particular to a fallopian tube embolus and a matching push device. Background technique [0002] Hydrosalpinx is a common complication of chronic salpingitis, often because the acute inflammation has not been cured, there is residual inflammation in the fallopian tube, which leads to tubal adhesion and atresia, and the lumen exudate or the remaining fluid after the absorption of pyometra forms hydrosalpinx , is a common factor causing female infertility, there is no satisfactory treatment. Hydrosalpinx contains microorganisms, lymphocytes and some toxic substances. The hydrosalpinx flows back into the uterine cavity, which not only has a toxic effect on the embryo, but may also wash the embryo and affect its implantation. The endometrial receptivity is reduced, and IVF- ET) embryo implantation rate and clinical pregnancy rate are limited, the success rate of clinical pregnancy ...
