Abstract

The utility model relates to a fallopian occluder for women, comprising a cylinder stainless steel casing and a filtering layer used for separating eggs from spermatozoa thereof. The utility model is characterized in that the head of the casing is provided with a spring steel wire hook which can thrust through and hang the oviduct wall after flicking. Usually, the compressed spring steel wire hook is bounded in fixing agent, and the tail of the casing is provided with screw threads matched with an applicator. In order to make the fallopian occluder arranged in the oviduct through vagina and uterus, the used applicator is provided with a flex socket which is penetrated with a freely telescopic rotary steel wire whose front end is connected with applied screws. The utility model has the advantages of convenient arrangement and no operation, the steel wire hook makes the fallopian occluder not fall off and shift, and the capacity to bear children can be recovered after the operation.

Description

Fallopian occluder

This utility model relates to women's contraception equipment, and the intratubal post of particularly a kind of insertion blocks up the sterillization device.

Existing women's methods of sterilisation, strict as tubal ligation to the sterillization person, multiple contraindication is arranged, various complication may appear in postoperative sterilization, when serious even can cause death.Thereby sterillization person has fear to ligation operation.And adopt stifled can under oviducal swing and wriggling, the excreting automatically of medicine bolt to make the sterillization failure to human body generation stimulation, particularly some medicine bolt.The common drawback of these methods is that hormone and the secretions that ovary produces can not normally be discharged through fallopian tube.At present existing a kind of energy sees through the stifled sterillization device of bolt of hormone and secretions, and it comprises stainless steel casing and filters sealing coat, and it is inserted the both sides isthmus of uterine tube, can stop ovum and sperm to meet, and reaches the sterillization purpose.The shortcoming of this method is to place by operation, and difficulty is bigger, still might come off after putting into, and also may artificially adopt improper mode to take out, and influences normally carrying out of family planning.

The purpose of this utility model is to overcome above-mentioned difficulties of the prior art, and provides a kind of not performing a surgical operation just the sterillization device can be placed into the apparatus of isthmus of uterine tube, and the sterillization device just can not come off once putting into again, unless adopt operation method to remove.

Solution of the present utility model is: the stainless steel spring hook that can pierce through and tangle tubal wall after the sterillization device head setting with cylindrical Stainless Steel Shell and isolation ovum, sperm filter course flicks, compressed at ordinary times carbine is strapped in the fixative, and the housing afterbody has the female thread that matches with applicator.After the agent of sterillization device internal fixation was dissolved by oviducal secreting liquid, carbine was released.For the sterillization device is put into isthmus of uterine tube by vagina and uterus, must adopt special applicator.This applicator has the sleeve pipe of a head-bent, is installed with the steel wire of a retractable and rotation in the sleeve pipe, steel wire one end join operation handwheel, and the other end connects the screw that matches with sterillization device female thread.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the sketch map that sterillization device and applicator are used.

Fig. 2 is a kind of shape figure of carbine.

Fig. 3 is the state diagram that places intratubal sterillization device.

Referring to Fig. 1, sterillization device 1 comprises cylindrical Stainless Steel Shell 12, is filled with filter course 13 in it, and filter course generally adopts thin stainless steel silk compacting to form, and the hormone that its permeance property produces ovary normally discharges through fallopian tube, does not influence the regulatory function to health.Housing 12 heads have inside crimping 14, the mouth of pipe is formed shrink.The stainless steel spring hook 15 of a double headed roller point is set between the mouth of pipe and sealing coat, and during the carbine free state, it is shaped as down 3 shapes, bends with steel wire to form, and sees Fig. 2.Carbine can also be made other analogous shape.When being pressed into carbine in the housing, shape is shunk, and strain takes place, and the arc shaped hook steeple is at the crimping place of the mouth of pipe.Pour into liquid fixative 17 afterwards, the carbine with contraction distortion after solidifying is enclosed in the fixative.Before fixative dissolves, carbine will remain the shape after the contraction.Fixative can be selected Alumen or salt one class material for use, and the better fixative of other performance.At housing 12 afterbodys female thread 16 is arranged, be used with the screw 25 of applicator.

Insert isthmus of uterine tube for above-mentioned sterillization device need not be performed the operation, must adopt special applicator 2, see Fig. 1.Applicator 2 has the sleeve pipe 21 of a head-bent, wears a stainless steel silk 22 in the sleeve pipe, steel wire one client link operation handwheel 24, and the other end connects the screw 25 that can screw in sterillization device tail end.Steel wire 22 can freely stretch and rotate in bend pipe 21.When the reverse rotation steel wire unclamps screw, sterillization device and applicator are broken away from.

During use, earlier applicator screw 25 is screwed in the sterillization device screw thread 16, the two is combined as a whole temporarily.Vaginal dilation, with applicator bend pipe transvaginal, the fallopian tube oral area is delivered in the uterus, behind the aligned position, promotes handwheel gently, makes steel wire 22 to protracting, and the sterillization device can be delivered to isthmus of uterine tube.Unscrew handwheel then, transmit moment of torsion by steel wire and give screw 25, screw is separated with the sterillization device, at last applicator is taken out, finish the dispensing process.Use the front spring steel wire hook to be confined in the fixative, do not expose the sterillization device.After inserting in the body, fixative slowly dissolves under the effect of ovarian hormone and secretions, and carbine restores to the original state under resilient force, and bill outwards pierces through tubal wall 31 automatically and returns and is hooked to sterillization device outer wall, sees Fig. 3.Simultaneously middle part ring 18 is stuck in the contraction place of the sterillization device head mouth of pipe, unlikelyly deviates from.

This sterillization device need not be performed the operation and can be placed isthmus of uterine tube, makes sperm can not reach the multiple portion of kettle and combines with ovum, reaches the sterillization purpose.The spring steel wire hook makes the sterillization device can not come off, be shifted, and has the permanent fixation effect, and non-underwent operative can not be taken off, to guarantee normally carrying out of family planning work.The deadweight of sterillization device is slowed down oviducal wriggling, swing, and ovum and sperm are lost vigor, and can't become pregnant.Do not influence simultaneously the normal discharging of ovarian hormone, this sterillization device is laid easy, need not perform the operation, and patient's no pain can be eliminated the fear of sterillization person to operation.When needing fertility, but still underwent operative is recovered fertility.
