Abstract
A sterilization suppository for woman is composed of a head with circular end, a connection part with a blind hole on its back surface and a locating part between said head and connection part and with a diameter less than that of said head and connection part. It can be put in uterine tube without operation.
Description
Described field: the present invention relates to women's contraceptive device, the intratubal sterilization embolus of particularly a kind of insertion, it can stop ovum to enter the uterus.
Background technology: existing women's methods of sterilisation, as tubal ligation, strict to the sterillization person, multiple contraindication is arranged, multiple complications such as hydrosalpinx, abdominal cavity infection, adhesion may appear in postoperative sterilization, when serious even can cause death, thereby sterillization person has fear to ligation operation, and tubal adhesive blocking agent is also safe and reliable inadequately.Adhesion-blocker shrinks in process of setting, break away from tube wall, and some is absorbed by the body discharge sterillization failure automatically under oviducal swing and wriggling.If stop up with the rustless steel key, very easily come off.Another shortcoming of these methods is that hormone and the secretions that ovary produces can not normally be discharged through fallopian tube.Though there is a kind of energy to see through the stifled sterillization device of bolt of hormone and secretions at present, it comprises wood rust outer steel shell and filters sealing coat, it is inserted the both sides isthmus of uterine tube, can stop ovum and sperm to meet, reach the sterillization purpose, but this method must be placed by operation, difficulty is bigger, still might come off after putting into, also may artificially adopt improper mode to take out, influence normally carrying out of family planning, in Cn91g01351, disclose a kind of method for designing of Woman sterilization stopper, its afterbody and inserter adopt thread connection because of mucus is arranged in the fallopian tube, smoother, sterilization embolus is difficult to separate with apparatus during operation, the also easy evil endophytic bacteria of filter screen wherein, make fallopian tube infection., this sterillization device is because unreasonable structure is failed by animal experiment, and existing a kind of contraceptive device is that in utero T shape is encircled, copper wire copper ion releasing in the juice of uterus of twining on it, have the effect of killing sperm more by force, thereby produce contraceptive effect.But in utero T shape ring is still safe and reliable inadequately.
Summary of the invention: the objective of the invention is to overcome difficulty of the prior art, and a kind of method for designing of Woman sterilization stopper is provided, it is not performed a surgical operation and just can insert intratubal sterilization embolus, can stop ovum and kill sperm, once putting into, difficult drop-off, and can have certain permeability.
Solution of the present invention is: design a kind of method for designing of Woman sterilization stopper, it is characterized in that: described sterilization embolus is that titanium TC4 material is made.
Described sterilization embolus is by location division and the bolt head structure that fuses by connecting portion (4), the bolt head is that round end (3), location division (2) external diameter are less than bolt head and connecting portion (4) external diameter, connecting portion is inserted blind hole in (4), and blind hole exports on connecting portion (4) rear end face.
Described connecting portion (4) is connected end face with location division (2) be the conical surface (7).
Be connected with by a plurality of slotted vanes (6) on the described location division (2) and form multiple-grooved face (2).
Described groove (6) lower curtate is concave surface (8).
The top of described round end 3 (5) is the plane.
Characteristics of the present invention are: this sterilization embolus is to be made of titanium TC4.Its connecting portion 4 is by location division 2 and circle bolt head 3 structure that fuses, the bolt head is a round end, location division 2 external diameters are less than the external diameter of circle bolt head 3 and connecting portion 4, thereby 2 damaged surface have the tubal wall of confession to be absorbed in otch or the some zigzag annular grooves that plays fixation in the location division, in order to block fallopian tube with titanium TC4 cylinder, the present invention adopts the structure of perforate, otch or annular groove that it is fixed in the fallopian tube, and solved people and thirsted for solving always, but the technical barrier of not succeeding all the time.
Description of drawings:
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is embodiment 1 structural representation.
Fig. 2 is embodiment 2 structural representations.
Fig. 3 is embodiment 3 structural representations.
The specific embodiment:
Among the figure: 1, insert jack; 2, location division; 3, justify the bolt head; 4, connecting portion; 5, bolt head; 6, slotted vane; 7, inclined-plane; 8, groove bottom.
Embodiment 1 as shown in Figure 1, sterilization embolus adopts titanium TC4 material to make.Its connecting portion 4 is by location division 2 and circle bolt head 3 structure that fuses, and the bolt head is a round end, and location division 2 external diameters are inserted blind hole less than the external diameter of circle bolt head 3 and connecting portion 4 in the connecting portion 4, and blind hole exports on connecting portion 4 rear end faces.Connecting portion 4 is connected end face with location division 2 be the conical surface 7.
Embodiment 2 as shown in Figure 2, its structure is basic identical with embodiment 1, difference just is connected with on location division 2 by a plurality of slotted vanes 6 and forms a plurality of grooves.The top 5 of circle bolt head 3 is planes.
Embodiment 3 as shown in Figure 3, the difference of it and embodiment 2 is that a plurality of trench bottoms that form at a plurality of slotted vanes 6 are concave surfaces 8.
Claims (6)
1, a kind of method for designing of Woman sterilization stopper is characterized in that: described sterilization embolus is that titanium TC4 material is made.
2, the method for designing of a kind of Woman sterilization stopper according to claim 1, it is characterized in that: its connecting portion (4) is by location division and the bolt head structure that fuses, the bolt head is that round end (3), location division (2) external diameter are less than bolt head and connecting portion (4) external diameter, connecting portion is inserted blind hole in (4), and blind hole exports on connecting portion (4) rear end face.
3, the method for designing of a kind of Woman sterilization stopper according to claim 1 is characterized in that: described connecting portion (4) is connected end face with location division (2) be the conical surface (7).
4, the method for designing of a kind of Woman sterilization stopper according to claim 1 is characterized in that: be connected with by a plurality of slotted vanes (6) on described location division (2) and form multiple-grooved.
