Description
Technical field
The present invention relates to a kind of women's fallopian tube contraception device, more particularly, it relates to a kind of by stopping that ovum enters oviducal reducible uterine tube birth control sleeve.
Background technology
At present, the non-hormone medical instrument of female contraception comprises barrier contraception, intrauterine device, tubal sterilization etc., and employing is all arranged clinically, and it respectively has pluses and minuses.Tubal sterilization is the female contraception method of wide clinical application, mainly comprises tubal ligation, fallopian tube ring, folder sterilization, fallopian tube gluing and stoping method, the stifled art of fallopian tube bolt etc.Various tubal sterilizations previously all mainly are by various mechanical blocking actions, to stop that sperm enters fallopian tube and reaches the birth control purpose, do not enter in the fallopian tube but do not influence ovum.Though tubal sterilization is a kind of easy, safe, operation efficiently, but the remarkable shortcoming of these methods is that recoverability is very poor, usually needing to carry out very complicated anastomosis of tube could recover fertility, be only applicable to give birth to and expect the women of permanent contraception, and tubal ligation, fallopian tube ring, folder sterilization also can influence the blood flow of fallopian tube and ovary, and certain side effect is arranged.Among these methods of tubal sterilization, use with the stifled art of fallopian tube bolt again the most extensive, below we just go through this method, to understand the pluses and minuses of tubal sterilization.The stifled art of fallopian tube bolt mainly is a mechanicalness thromboembolism fallopian tube, and the embolus laying method is that selectivity fallopian tube intubate is sent the stifled thing of bolt into matter portion or isthmus between fallopian tube under the hysteroscope.The stifled art of fallopian tube bolt mainly comprises following several method clinically at present: 1. P-block bolt, 2. silica gel " Ouabloc " bolt, 3. nylon birth control bolt (ITCD), 4. common oviduct IUD (Intratubal Contracep tiveDevice in the fallopian tube, be called for short ITCD), 5. ESSURE.Studies show that above-mentioned each mode all exists after the birth control can not annealing issues, places the P-block bolt after 2～3 years, tubal wall tissue is grown in the porous gel on embolus surface, and embolus takes out the back recanalization rate, and to reach pregnant again rate lower.Silica gel " Ouabloc " in case after the molding of bolt fluid injection silica gel, be difficult to accomplish its monoblock is taken out and do not tear the fallopian tube proximal part, so that bolt can be thought is permanent.Domestic novel common oviduct IUD does not carry out recoverability research as yet.It is the intrafallopian contraception embolus of non-recoverability that ESSURE is considered to according to its design principle, and the excision of embolus need be carried out abdominal operation.Because metal ingredient wherein, perform the operation used electric knife, radio frequency, microwave etc. all need be avoided the embolus position, so ESSURE there is no advantage aspect recoverability.
In order to solve the problem of fertility recoverability, Chinese invention patent 00117549.1 (open day: March 28 calendar year 2001, publication number: CN 1288714A) disclose a kind of " contraceptive air bag suppository device ", also be a kind of to stop that sperm enters the method that fallopian tube reaches the birth control purpose, but ovum can enter in the fallopian tube, it places installation method and approach is: under hysteroscope, by cavity of uterus matter portion and isthmus intubate between fallopian tube, air bag is sent into matter portion or isthmus between fallopian tube.Because matter portion and isthmus always are about 2～3cm between fallopian tube, tube chamber is superfine, the only about 1mm of diameter, and both intersections also are the thinnest oviducal places; Simultaneously, also have abundant angular intrauterine Musclar layer between fallopian tube outside the matter portion, make matter portion tube wall shortage retractility between fallopian tube.Make one when not full, diameter is only less than the thick miniature air bag device of 1mm, and with this miniature air bag device " insertion " that has no the hardness of supporting only 1mm, tube wall lack in the narrow and small tube chamber of matter portion between the fallopian tube of ductility or isthmus to diameter, not only the making of this micro device is very difficult, the implant procedure process is also very complicated, and degree of difficulty is also extraordinary.Same, will only the working place of 1mm be also unusual difficult and complicated with the complete taking-up of this miniature air bag by one, the feasibility that does not have reality, be difficult to implant, can't fix, skid off easily and be shed to cavity of uterus, after implanting, because of matter portion tube chamber between fallopian tube too little, though balloon tamponade too tightly helps fixing, but because of the wall of this miniature air bag too poor, be placed on matter portion between a cornua uteri fallopian tube that lacks cushion space again, as easy as rolling off a logly cause the air bag pressurized to break (particularly uterus pressurized or aging fracture automatically during sexual life) and fail, if airbag wall is too thick, how to make the miniature air bag of an overall diameter again less than 1mm? the miniature air bag device of implanting is because long-time stimulation adhesion is narrow, tissue factor such as grow into makes the more difficult taking-up of this micro device, even successfully take out, also may make this narrow and small tube chamber locking etc. because of factors such as damages, still need coincide at the fallopian tube of the descending complexity of microscope and rebuild or the like, therefore, can not reach recoverability on the original design sense.In fact, even miniature air bag is not full, the short space of matter portion or isthmus between just having taken, become the stifled thing of bolt of an entity, the real airbag structure on the design sense originally, simultaneously, the full of air bag can not be observed full situation under direct-view, cause the air bag underfilling easily, perhaps over filling just can make balloon rupture failure slightly, even can make fallopian tube impaired during balloon rupture.And, this class enters the method for birth control that fallopian tube is a purpose with " interception " sperm, " in case interception " sperm failure, with can enter oviducal ovum and join, may cause the situations such as great risk of ectopic pregnancy, can not reach after durable in use, the birth control a series of designing requirements such as recoverability, cause this invention not see the research reported literature so far, just one breaks away from the theory vision of realizing.
The fimbriated extremity of fallopian embedding, the ovary embedding techniques, principle is: after ovum is produced by ovary, enter into fallopian tube a space length is arranged, ovum has the ability of freely walking about unlike sperm, ovum itself does not have " walking about " function, ovum enters oviducal this space length and waits by oviducal wriggling after by fimbriae of uterine tube " seizure " ovum (picking up ovum) again and realize change in location, utilize this space length, with peritoneum ovary and fallopian tube are separated into two different spaces: behind abdominal cavity and the peritoneum, make fimbriae of uterine tube can't " catch " ovum, stop that ovum enters fallopian tube, but this operation technique is extremely complicated, wound is very big, the mortality height is eliminated.
