The invention is suitable for the embryo pregnant for more than 8 weeks, does not need medicine injection, and has small operation range, short operation time and small residual slough.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially relate to a kind of embryo-reduction device.
Background technology
Transplanting along with a plurality of embryos in the application of promoting ovulation drug and the auxiliary procreation technology obviously raises the incidence rate of multiple pregnancy, has caused trimester of pregnancy complication and enclose newborn baby's case fatality rate and rise.Because of the premature infant or the low birthweight infant of multiple birth, in the growth of physique and intelligence, also can be affected simultaneously.Therefore, multiple pregnancy is a comparatively severe complications of auxiliary procreation technology, and controlling multiple pregnancy effectively is the problem that pay much attention to.
Fetal reduction is a kind of remedial measure for multiple pregnancy, has become indispensable technology.From the eighties in 20th century, (multifetalpregnancy reduction MFPR), along with the development of ultrasonic technique, subtracts tire to multiple pregnancy and carries out Wicresoft and be treated as possibility to begin to attempt the multiple pregnancy fetal reduction for the above gestation of triplet.
Up to the present, the main method that subtracts tire at the early stage transvaginal of gestation has: three kinds of plumule suction methods, mechanical damage method, medicine injection method.
1) plumule suction method: promptly utilize puncture needle to add negative pressure merely, be suitable for for 6～8 pregnant weeks, but, be difficult for sucking-off because of the embryo is excessive for above embryo of pregnant 8 weeks with embryonal tissue's sucking-off.
2) medicine injection method: promptly puncture needle enters the fetal rhythm part, injects medicine and causes embryonic death.Be suitable for any pregnant week.The possibility that this method exists fetal rhythm to jump again, and the medicine that injects may enter other embryo by the blood circulation communicating branch that exists between the embryo, causes to keep embryo's miscarriage, and the odd-shaped probability of neonate takes place increase.
3) mechanical destruction method: be fit to above embryo of pregnant 8 weeks.A. promptly enter embryo's primitive heart tube district of beating and rotate puncture needle repeatedly, or use and strangle 360 ° of instrument rotations, disappear until fetus heart beating with puncture needle; B. use the single chamber of 17G puncture needle, smash the embryo to pieces and with the sucking-off of embryo's fragment with acupuncture.This method is bigger because of the uteroventral operation amplitude, and the operating time is long, and residual slough is more, easily causes the postoperative abortion ratio to increase.
Correlational study shows, the early abortion that takes place behind the fetal reduction may be relevant with partial aseptic inflammation reaction, residual slough is many more, and inflammatory mediators such as the cytokine of local accumulative inflammatory cell and release, prostaglandin are also many more, bring out uterine contraction and cause that the probability of miscarriage is also big more.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of embryo-reduction device; This embryo-reduction device is applicable to above embryo of pregnant 8 weeks, need not to inject medicine, and operation amplitude is little, and the operating time is short and residual slough is less.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: it comprises puncture needle body and signal emitting plate, and this puncture needle body is a hollow structure; Be provided with motor in the needle point place of described puncture needle body, this motor one end is fixed with output shaft, the output shaft tip is provided with rotating vane, during non-working condition, this rotating vane position is in the hollow structure of puncture needle body tip, the other end of described motor sets firmly a screw rod, this screw rod and a screw rod pusher threaded engagement, and described screw rod pusher is fixed on the inwall of puncture needle body by support; And described screw rod pusher is provided with flexible signal receiver, and the rotation of this screw rod pusher can make elongate screw or shortening, thereby it is flexible to drive motor; Described motor is provided with the switching signal receptor, and described signal emitting plate is provided with and the switching signal emitter of switching signal receptor coupling and the flexible signal projector that mates with flexible signal receiver;
Further, described motor casing circumference is provided with at least 3 fixed lobes, and this projection can make motor be in steady statue at puncture needle body hollow structure.
Further, the blade edge of described rotating vane is the sharp knife edge.
The present invention has following beneficial effect:
1) applicable to above fetal reduction of pregnant 8 weeks;
2) simple to operate---acupuncture only needs by after switch activated behind the embryo, and the limit blends embryo limit sucking-off embryonal tissue;
3) operating time is short---and above-mentioned manual methods is rotated puncture needle repeatedly, change into electronicly, saved operating time;
4) the uteroventral operation amplitude is little---and trocar sheath does not change, and inner core rotates, and has reduced the stimulation to the uterus;
5) need not use medicine---avoided medicine to enter the miscarriage that other embryos cause;
6) residual tissue is few---and embryonal tissue is blended and sucking-off, and less embryonal tissue residual reduces the stimulation of residual tissue to the uterus, and complication such as coagulation disorders appears in postoperative to be reduced;
7), can improve the success rate and the safety of fetal reduction, the abortion ratio behind the reduction fetal reduction based on preceding 6.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to shown in Figure 1, the present invention includes puncture needle body 1 and signal emitting plate 2, this puncture needle body 1 is a hollow structure, is provided with motor 11 and screw rod pusher 12 in this hollow structure; Described motor 11 1 ends are fixed with output shaft 111, output shaft 111 tips set firmly rotating vane 112, these rotating vane 112 edges are sharp knifes edge, during non-working condition, these rotating vane 112 positions are in puncture needle body 1 tip hollow structure, the other end of described motor 11 sets firmly a screw rod 113, and this motor 11 is provided with switching signal receptor 114, described motor 11 shell circumference are provided with at least 3 fixed lobes 115, and this projection 115 can make motor 11 be unlikely in puncture needle body 1 hollow structure to vacillate now to the left, now to the right; Described screw rod 113 and a screw rod pusher 12 threaded engagement, this screw rod pusher 12 is fixed on the inwall of puncture needle body 1 by support 121, and described screw rod pusher 12 is provided with flexible signal receiver 122, the rotation of this screw rod pusher 12, screw rod 113 is elongated or shortened, thereby it is flexible to drive motor 11; Described signal emitting plate 2 be provided with the switching signal emitter 21 of switching signal receptor 114 coupling, with the flexible signal projector 22 of flexible signal receiver 122 couplings.
