Abstract

The invention discloses a uterine placement cage for terminating pregnancy, which comprises a T-shaped placement cage. Fallopian tube accessing sleeves are symmetrically arranged at two sides of the placement cage; and the placement cage is also connected to the uterus through a uterine neck accessing sleeve. The T-shaped placement cage is woven by fine weaving fibers with elasticity and memorability; and the woven fibers are made of metal or non-metal materials. The uterine placement cage for terminating pregnancy disclosed by the invention which is made of copper is simple in structure and can terminate pregnancy after being placed in a uterus. Due to the isolating function of the uterine placement cage for terminating pregnancy, when a blastosphere formed by a fertilized ovum is not implanted on an endometrium, the blastosphere is easy to separate from the uterus, the blastosphere and the uterus that are even apparently severed but actually connected can also be separated thoroughly by shearing and twisting among the weaving fibers. As the fertilized ovum is not implanted finally and is not substantially combined with a uterine wall, bleeding is avoided in a surgery. Thus, the uterine placement cage for terminating pregnancy disclosed by the invention can greatly ease pain of women in the surgery and can also enable the surgery to be simple and rapid.

Description

Cage is placed in the uterus of termination of pregnancy
Technical field
The present invention relates to a kind of instrument of termination of pregnancy, cage is placed in the uterus that relates in particular to a kind of termination of pregnancy.
Background technology
Gestation is that the women of child-bearing age hope to give birth to the healthy baby of oneself concerning the major issue of women's life security, healthy and following happiness.Yet some fortuitous events cause the women conceived sometimes, are that they are badly in need of and will stop immediately: the for example unprotect property sexual intercourse of the onset of ovulation,, contraceptive unexpected inefficacy violent by the ruffian or the like.Doctor or individual take some technical measures, and for example taking some contraceptive (visiting pill etc.) changes germ cell normal running speed in fallopian tube.Make germ cell arrive uterine cavity in advance, and endometrium did not still possess the implantation ability this moment, that is disturbed germ cell and endometrial synchronous variation, thereby the germ cell implantation is interfered.But, not playing effect if there is suitable contraceptive can obey or take hysteresis, medicine, people have to see helplessly that germ cell gets into the uterus and begins gestation.After 35 days, wait fetus long to certain size, doctor when performing an operation, can see it also can take out from intrauterine, could be through the artificial abortion termination of pregnancy.Miscarriage is very big to the body of women health hazards, possibly cause sometimes that the women's is sterile all the life.And some countries do not allow the women to miscarry, and this can be suffered violent women's life to stay especially big disaster.
We know that the prerequisite of gestation is that germ cell gets into the uterus.Sperm gets into fallopian tube through vagina, cervix uteri, uterus, and ovum becomes germ cell after zift.Germ cell is just returned trip and is got into the uterus after fallopian tube moves about couple of days.At this moment, germ cell has become the embryonic cell crowd that 8~16 cells are arranged, i.e. a morula through division several times.
Morula gets into the uterus; Can be tangled by the silk ribbon of uterus zostera marina shape, and then sticked, at this moment by the mucus in uterus; It is not also taken root in the uterus and settles; Only be in the uterus, to suspend, floating, and absorb nutrition fully and proceed cell division, until becoming a blastaea that cell divide is arranged that has a beginning and an end.Beginning in the 7th day, healthy blastomere can grow a drill bit that little tail is the same, is used for piercing Uterus wall, can develop into the umbilical cord that links to each other with parent later on.
That is to say, behind the ovum fertilization, just can on Uterus wall, find a suitable and comfortable position at the 7th~10 day blastaea.This position generally is to be positioned at the bottom of the palace, and how rear wall (fewer at antetheca).This moment, germ cell one end is close to endometrium, secretes a kind of enzyme of decomposing protein at once, dissolves endometrium, forms the breach of about 1 millimeter of diameter.Blastocyst is promptly imbedded endometrium from indentation, there, and the epithelium breach is repaired rapidly, and completion is promptly accused in settling down of blastocyst.This process medically is called the implantation or the implantation of germ cell.In several days that germ cell is gone around in the uterus, if we can stop germ cell one end to be close on the endometrium effectively, so, the implantation of back just can not form, and gestation just can not continue.
Summary of the invention
The object of the invention is exactly in order to address the above problem, and provides a kind of uterus with termination of pregnancy function to place cage.
To achieve these goals, the present invention adopts following technical scheme:
Cage is placed in the uterus of termination of pregnancy, and it comprises T type placement cage, and said placement cage lateral symmetry is provided with fallopian tube and inserts tube, and said placement cage also inserts socket joint through cervix uteri and goes into the uterus.
Said T type is placed cage and is adopted the thin braided wires establishment with elasticity and Memorability, and said braided wires adopts metal or nonmetallic materials to process.
The device of cage is placed in a kind of uterus of placing termination of pregnancy, and this device comprises the manipulation dragline, handles dragline and is connected with push-plate, and push-plate is located in the operation technique trocar sheath, and the operation technique trocar sheath inserts tube with cervix uteri and matches.
The device of cage is placed in a kind of uterus of taking out termination of pregnancy, and this device comprises the manipulation dragline, handles dragline and is provided with manipulation dragline termination point casing, handles the dragline termination and is with the termination that four termination point casing positioning pillars are fixed on the operation technique trocar sheath; Be provided with in the said manipulation dragline termination point casing and take off hook.
Beneficial effect of the present invention is following: the uterus of termination of pregnancy is placed cage and is adopted copper, inserts the effect that can play contraception behind the uterus; Because the buffer action of cage is placed in the uterus of termination of pregnancy, the blastaea that germ cell forms is implantation on uterine veil not, and separate with uterus than being easier to this moment, though somewhat separated but still in each other's thoughts, also can be owing to cutting, twisting and thoroughly separating between each establishment silk.Because germ cell does not have last implantation and Uterus wall not to have to be bound up substantively,, also make operation simple and easy fast so operation does not have bleeds, and can alleviate operation women's misery so greatly.

Wherein, 1, fallopian tube inserts tube, 2, the establishment silk, 4, the operation technique trocar sheath, 5, place cage, 6, cervix uteri inserts tube, 7, push-plate, 8, handle dragline, 9, take off hook, 10, handle the dragline termination point casing, 11, termination point casing positioning pillars.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Be illustrated in figure 1 as front view of the present invention, wherein, the filament material manufacturing that cage adopts fine diameter is placed in the uterus, and this material has good elasticity and has memory function.It can be shrunk to a bar shaped, sends into the uterus with operating theater instruments, after from apparatus, releasing the entering uterus, recovers shape memory, and its axonometric drawing is Fig. 2.
It is a bit of that fallopian tube inserts tube 1 entering fallopian tube, and cage top is limited and restraint therefore.Cervix uteri access tube 6 is stayed cervix uteri after cage is admitted to the uterus a bit of, and the bottom of same cage also is able to fix.
Establishment silk 2 can adopt metal, also can adopt nonmetallic materials such as plastics, nylon or other synthetic materials, but must meet the requirement of elasticity and Memorability.Because fallopian tube inserts the location of tube 1 and cervix uteri access tube 6; All establishment silks all leave uterus inwall one segment distance; Special at the bottom of the palace and these morulas of rear wall position of implantation very easily, guarantee that " the little tail " of blastaea reaches endometrium that is guarantee that it can not implantation.
Place cage when morula gets into the uterus by fallopian tube, place cage and just blastaea and Uterus wall are separated, blastaea can be connected to absorb nutrient through silk ribbon with Uterus wall, grows up rapidly, and its individuality is big more, is beneficial to more with uterus placement cage and takes out together.
The uterus of termination of pregnancy is placed the cage fallopian tube and is inserted tube 1 and insert tube 6 with cervix uteri and adopt coppers with part establishment silk 2, inserts the effect that can play contraception behind the uterus.Because copper can form the copper ion high concentration region in uterus, can disturb sperm entering fallopian tube and embryo film implantation in uterus effectively.
That is to say that when fallopian tube inserted tube 1 and cervix uteri and inserts tube 6 and adopt a non-copper product to make with establishment silk 2, the uterus of termination of pregnancy was placed cage and only played the effect that stops the germ cell implantation; And when adopting copper material to make, can play the effect that stops the germ cell implantation, play the effect of contraception again.
Lost efficacy if the contraception function of cage is unexpected, and also can make the germ cell that is back to come in the uterus isolate endometrium, termination of pregnancy effectively.Because the user situation is special, even placing cage, the termination of pregnancy and the bifunctional uterus of practising contraception can not in time take off on one's body from user, blastular also can be owing to can not perishing of oneself at last by implantation.
Fig. 3 places the operational illustration yet of cage for the uterus of placing termination of pregnancy; Before the operation; Place cage 5 radial contraction to the uterus of termination of pregnancy, earlier cervix uteri is inserted tube 6 and push operation technique trocar sheath 4, again the cage body is slowly filled in subsequently; But the cage that gets into operation technique trocar sheath 4 is not carried out the compression of length aspect, push away to come out when too tightly performing the operation with antifouling.Because not only soft, but also the Memorability of flexible and shape of the used establishment silk of cage 5 is placed in the uterus of termination of pregnancy.So not worrying the uterus of termination of pregnancy places cage 5 and can plastic deformation occur because of contraction.
Behind the above-mentioned end-of-job, can operation technique trocar sheath 4 be pushed the uterus through vagina, cervix uteri.When soon arriving at the bottom of the palace, promote to handle dragline 8, cage 5 slowly release from operation technique overcoat 4 in is placed in the uterus of termination of pregnancy by push-plate 7.
As shown in Figure 3; What be pushed out at first is that two fallopian tube insert tube 1; It is made that they work out silk preferably by pliability, elasticity and shape memory, recovers shape lentamente, and at this moment the operator constantly adjusts the position; Stretch to fallopian tube along with the cage body constantly is pushed out and makes fallopian tube to insert tube 1, and phase in.
At last, it is a bit of that cervix uteri access tube 6 is stayed cervix uteri, retracts gently and handle dragline 8, and operation technique trocar sheath 4 is also released vagina thereupon, and operation promptly comes to an end.
Fig. 4 places the operational illustration yet of cage for the uterus of taking out termination of pregnancy; Visible among the figure; The operation compared that cage is placed in cage and the uterus of placing termination of pregnancy is placed in the uterus of taking out termination of pregnancy, manyly in the operation tool takes off hook 9, handles dragline termination point casing 10 and termination point casing positioning pillars 11.
Fig. 4 is visible, and cervix uteri inserts the taper of tube 6 lower ends, is when placing cage 5 for the uterus of taking out termination of pregnancy, is convenient to operation technique trocar sheath 4 and gos deep into Cervical operation and establish.Operation technique trocar sheath 4 per vaginam arrives cervix uteri lentamente.Then, promote to handle dragline 8, make and take off hook 9 inserts tube 6 from cervix uteri inwall entering uterus.
Take off former being compressed in relatively separately before this of four grapples of hook 9 and handle within the dragline termination point casing 10, this termination point casing is fixed on the termination of operation technique trocar sheath 4 by four termination point casing positioning pillars 11.
Operation dragline termination point casing 10 is along with operation technique overcoat 4 is pushed into cervix uteri forward, and termination point casing 10 is inserted tube 6 by cervix uteri to be stoped.Because it is identical with the internal diameter of operation dragline termination point casing 10 that cervix uteri inserts the internal diameter of tube; So; Handle dragline 8 and continue to move ahead, when it after cervix uteri inserts tube 6 upper ends and stretches out, its termination take off hook 9 opposing outer bullets; Take off hook and just in time take off above cervix uteri access tube 6, the uterus placement cage 5 that this moment, the limit up advanced past manipulation dragline 8 termination of pregnancy of pulling back in operation technique trocar sheath 4 limits is just immediately by the inwall of income operation technique trocar sheath 4.
When the uterus placement cage 5 of termination of pregnancy was packed up pulling, its two fallopian tube inserted tube 1 elder generation and break away from fallopian tube.Operation technique trocar sheath 4 should arrive near the position at the bottom of the palace at this moment.Place the contraction of cage, make that the spacing between the establishment silk is more and more littler, germ cell is sandwiched in therebetween.
Because the buffer action of cage 5 is placed in the uterus of termination of pregnancy, the blastaea that germ cell forms is implantation on uterine veil not, and separate with uterus than being easier to this moment, though somewhat separated but still in each other's thoughts, also can be owing to cutting, twisting and thoroughly separating between each establishment silk.
Because germ cell does not have last implantation and Uterus wall not to have to be bound up substantively,, also make operation simple and easy fast so operation does not have bleeds, and can alleviate operation women's misery so greatly.
Though the above-mentioned accompanying drawing specific embodiments of the invention that combines is described; But be not restriction to protection domain of the present invention; One of ordinary skill in the art should be understood that; On the basis of technical scheme of the present invention, those skilled in the art need not pay various modifications that creative work can make or distortion still in protection scope of the present invention.
