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
The present invention relates to the treatment of a kind of hydrosalpinx auxiliary facilities, in particular a kind of fallopian tube embolus and matching used pusher.
Background technology
Hydrosalpinx is the common complication of chronic salpingitis, Chang Yinwei acute inflammation is without healing, the inflammation of rear something lost is had to cause fallopian tube adhesion and locking in fallopian tube, after tube chamber transudate or pyosalpinx absorb, remaining liq forms hydrosalpinx, be the common factors causing infertility, there is no satisfied Therapeutic Method at present.Containing microorganism, lymphocyte and some noxious substances in hydrosalpinx, hydrops backflows into uterine cavity, not only to the toxic effect of embryo, also may wash away embryo and affect its implantation, endometrium receptivity reduces, Embryo Implantation Rate in and the Clinical Pregnancy Rate in of test-tube baby (IVF-ET) are all restricted, the clinical pregnancy success rate merging hydrosalpinx only has 10-20%, and rate of spontaneous abortion comparatively significantly raises without hydrops person, therefore, before carrying out test-tube baby, various prevention hydrops is adopted to flow into the method for uterine cavity to improve the effect of test-tube baby.The main pretreatment mode of hydrosalpinx divides 4 kinds both at home and abroad at present, and salpingectomy, salpingostomy, therapy of oviduct ligation and B ultrasonic aspirate hydrosalpinx under monitoring.Former three all need be performed the operation under peritoneoscope or through abdomen, operation process may damage the vessel branch of utero-ovarian, cause ipsilateral ovarian blood for reducing, ovarian function is had a certain impact, although and aspirate hydrosalpinx and can not affect the confession of ovary blood, have the possibility that tubal pregnancy and hydrops again occur.Embolism for fallopian tube art is in early days for fallopian tube contraception art, development in recent years is at IVF-ET pre-treatment hydrosalpinx, this new Therapeutic Method both can not damage ovary Peripheral blood and supply, tubal pregnancy and hydrops recurrence can be avoided again, compensate for the deficiency of above 4 kinds of methods, make patient avoid pain of surgery.
The material blocked up for hydrosalpinx bolt clinically is at present the microcoils of a platinum material, original purposes is that bolt blocks up blood vessel, under x-ray monitors, by microtubular, microcoils is sent into interstitial tubal, the advantage of microcoils does not damage the blood supply of mesosalpinx and ovarian artery, easy, safety, without complication, shortcoming is material expensive, and roentgen radiation x is also unfavorable for women 's fertility.Place the patient's radiography again after embolus, find reach the complete bolt of fallopian tube block up effect close to 100%, after clinical research retrospective analysis Embolism for fallopian tube, patient carries out the clinical effectiveness of IVF-ET, find that pregnancy rate is similar with the treatment effect of neostomy to salpingectomy under peritoneoscope, but which reduce operation risk, do not affect the blood supply of ovarian artery, little on the impact of ovarian function, be conducive to the success rate improving IVF-ET.
The treatment of Embolism for fallopian tube is an innovation, effective method, compared with method conventional at present, without operation and complication of anesthesia, easy, safety, economical, on ovarian function without impact, improve the clinical effectiveness of test-tube baby, have good potential applicability in clinical practice.
Although can see product or the design of fallopian tube embolus at home and abroad, these emboluses all carry out sterillization use, its design are also unfavorable for the bolt resistance treatment of the hydrosalpinx of supplementary reproduction.Such as, these emboluses are all fixed on uterine tube stegnosis portion, and reserve a segment trailer in uterine cavity, are beneficial to cause the inflammatory reaction having sterilization effect, and are also conducive to taking out embolus in the future.But this pattern creates sterilization effect while bolt resistance, is not suitable for the supplementary reproduction object of hydrosalpinx treatment.
Current do not have the hydrosalpinx bolt of supplementary reproduction to hinder special embolus, the fallopian tube embolus of sterillization is not suitable for helping the hydrosalpinx bolt of reproduction to hinder, and the microcoils adopting bolt to block up the platinum material of blood vessel at present hinders as hydrosalpinx bolt, it is material expensive not only, and need under roentgen radiation x, carry out bolt resistance operation and be also unfavorable for women 's fertility, also block up the design of blood vessel because of bolt simultaneously and be not exclusively applicable to fallopian tube structure and the Shi Youshuan resistance situation such as to come off occurs.
Summary of the invention
