Abstract
The invention aims to provides an embryo transfer device and an application method thereof. By the embryo transfer device and the application method thereof, the embryo can be transferred to a correct position in uterus accurately under ultrasonic guidance so that embryo transfer success rate is increased. The embryo transfer device comprises a hard supporting core, a transfer tube and a guide tube, both the transfer tube and the guide tube are through, and an echo steel coil is arranged at the front end of the guide tube. The application method of the embryo transfer device includes steps of A, placing the supporting core into the guide tube, inserting the guide tube into the uterus, observing the position of the echo steel ring in the guide tube by an ultrasonic unit, regulating the guide tube until the guide tube locates at a proper position of the transferred embryo, and then removing the supporting core; B, connecting an injector with the transfer tube carrying the to-be-transferred embryo, inserting the transfer tube into the guide tube, regulating the position of the transfer tube relative to the guide tube until the transfer tube locates at the proper transfer position; and C, utilizing the injector to carry out implanting of the embryo, and then removing the guide tube and the transfer tube so as to complete the embryo transfer process.
Description
Technical field
The invention belongs to the medical treatment consumptive materials technical field, specially refer to a kind of accurate orientation direction pipe position that is conducive to, thereby improve embryo transfer device and the using method thereof of Success Rate of Embryo Transfer.
Background technology
Existing embryo transfer device normally is located at the echo steel ring end of the grafts that loads the embryo, and in the embryo transfer process of reality, what at first insert is guiding tube rather than grafts, therefore at the transplanting pipe end echo steel ring being set has little significance, though the metallic support core is arranged in the guiding tube, and diameter is meticulous, the echo intensity under ultrasonic a little less than, the position that often is difficult to accurate orientation direction pipe has influence on embryo's implantation and pregnancy outcome the most at last.
Summary of the invention
The objective of the invention is to propose a kind of embryo transfer device and using method thereof, can under ultrasonic guidance, exactly the embryo be put into the suitable position of intrauterine, improve Success Rate of Embryo Transfer.
Embryo transfer device of the present invention comprises the supporting-core of hard and grafts, the guiding tube of perforation, and key is that the front end of described guiding tube is provided with echo steel figure.
The using method of above-mentioned embryo transfer device comprises the steps:
A: supporting-core is put into guiding tube, then with the guiding tube intron in utero, utilize Vltrasonic device to observe the position of the echo steel ring of guiding tube, adjust guiding tube, until guiding tube is in the correct position of transplanting embryo, withdraw from supporting-core;
B: syringe and loading are remained the grafts of transplanting embryo link to each other, and grafts is inserted in the guiding tube, adjust grafts with respect to the position of guiding tube, thereby grafts is positioned at suitable implant site;
C: utilize syringe to carry out the embryo and implant, then escape leading pipe, grafts are finished embryo transfer.
Further, the surface of the handheld terminal of the front end of described guiding tube, grafts is equipped with scale.
In the B step of the using method of above-mentioned embryo transfer device, judge with respect to the position of guiding base whether the front end of grafts is concordant with the front end of guiding tube by the scale that the handheld terminal of observing grafts is provided with, when the front end of grafts was concordant with the front end of guiding tube, the expression grafts had been positioned at suitable implant site.
Grip and the adjustment position for convenient, the handheld terminal of described guiding tube is provided with the guiding base, and the handheld terminal of described supporting-core is provided with the support core print seat, and the handheld terminal of described grafts is provided with the transplanting base.
Echo steel ring in the embryo transfer device of the present invention is arranged on the guiding tube, can widen than existing product, strengthened echo intensity, be conducive under ultrasonic guidance, accurately locate, minimizing is to endometrial damage and stimulation, improve the success rate of embryo transfer, therefore have good practicality.
Description of drawings
Fig. 1 is the structural representation of the embryo transfer device of embodiment 1.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the embryo transfer device of present embodiment comprises guiding tube 1 and the grafts 3 of perforation, and the supporting-core 2 of hard, wherein the handheld terminal of guiding tube 1 is fixed with guiding base 4, guiding base 4 has the catheter hub that communicates with guiding tube 1, the front end of guiding tube 1 is provided with echo steel ring 5, and front-end surface is provided with the scale 6 that is spaced apart 1cm; The handheld terminal of supporting-core 2 is fixed with and supports core print seat 7, and supporting-core 2 is built-in with rustless steel filling core 8; The handheld terminal of grafts 3 is fixed with transplants base 9, transplants base 9 and has the syringe jack that communicates with grafts 3, and the handheld terminal surface of grafts 3 is provided with the scale 10 that is spaced apart 1cm.
Above-mentioned embryo transfer device using method is as follows:
A: supporting-core 2 is put into guiding tube 1, then with guiding tube 1 intron in utero, in the position that utilizes scale 6 observation guiding tubes 1 simultaneously, utilize Vltrasonic device to observe the position of the echo steel ring 5 of guiding tube 1, adjust guiding tube 1, until guiding tube 1 is in the correct position of transplanting embryo, withdraw from supporting-core 2;
B: syringe and loading are remained the grafts 3 of transplanting embryo link to each other, and grafts 3 is inserted in the guiding tubes 1, adjust grafts 3 with respect to the position of guiding tube 1, thereby grafts 3 is positioned at suitable implant site;
C: utilize syringe to carry out the embryo and implant, then escape leading pipe 1, grafts 3 are finished embryo transfer.
In the B step of the using method of above-mentioned embryo transfer device, judge with respect to the position of guiding base 4 whether the front end of grafts 3 is concordant with the front end of guiding tube 1 by the scale 10 that the handheld terminal of observing grafts 3 is provided with, when the front end of grafts 3 was concordant with the front end of guiding tube 1, expression grafts 3 had been positioned at suitable implant site.
