Specific embodiment

In order to have further understanding to the technical solution of the utility model and beneficial effect, with reference to the accompanying drawing in detail Illustrate the beneficial effect of the technical solution of the utility model and its generation.

The utility model is intended to be directed to requirement during embryo transfer, to the accuracy of embryo transfer amount, examines simultaneously Consider the faint environment in portion into the human body, providing one kind can accurately control into cervix opening depth, and can accurately control and be transplanted The embryo transplanter of volume of embryo improve Success Rate of Embryo Transfer to improve the deficiencies in the prior art.

Fig. 1 is the structural schematic diagram of the embryo transplanter of the utility model, and Fig. 2-Fig. 4 shows the embryo of the utility model respectively The structural schematic diagram of grafts used in tire grafting device, outer tube and syringe, incorporated by reference to shown in Fig. 1 to Fig. 4, this is practical The embryo transplanter of novel offer, comprising: for obtaining the grafts 10 of embryo and embryonal vaccination, for protecting grafts 10 Outer tube 20 and the syringe 30 for being used to help grafts 10 acquisition embryo and embryonal vaccination, now to the detailed structure of each component Details are as follows with function.

Please refer to shown in Fig. 1 and Fig. 2, for grafts 10 as the tool for directly acquiring embryo, one end is injection port 11, The other end is liquid taking port 12, and injection port 11 is directly contacted with embryo when obtaining embryo, when squeezing into embryo to human body, directly It squeezes into the uterine neck of human body；Liquid taking port 12 is contacted with syringe (aftermentioned)；Since grafts 10 need portion envelops in outer tube In 20, it is contemplated that obtain embryo, embryonal vaccination and be extended through in outer tube 20 and squeeze into the intracorporal needs of people to facilitate, this is practical The novel endpiece for setting grafts 10 to include the middle section part 13 being made of metal material and be made of transparent softwood matter Part 14, when grafts 10 are wrapped in 20 inside of outer tube, the middle section part of grafts 10 is wrapped up by outer tube 20 completely, Tail portion then stretches through out outside outer tube 20, and middle section part 13 is set as metal material, is to be penetrated in outer tube 20 for convenience, Tail portion 14 is set as transparent softwood matter, allows for when squeezing into embryo, this part is directly entered in human body uterine neck, therefore The material of tail portion 14 should select to be set as the inside microenvironment that will not be damaged to human body as far as possible.Please continue to refer to shown in Fig. 2, Certain angle is presented relative to middle section part 13 for the tail portion 14 of grafts 10, is preferably in 110-120 degree, in order to fall It sets and draws embryo manually under microscope or stereoscope.

Please refer to shown in Fig. 1 and Fig. 3, component of the outer tube 20 as cladding grafts 10 is used to beat to human body When entering embryo, middle section part 13 and the inside of human body of grafts 10 are environmentally isolated, in case metal material will cause human body not It is suitable；Another function of outer tube 20 is to indicate that entire embryo transplanter squeezes into human body by its external indicating ring 21 being arranged Depth, specifically, indicating ring 21 is slideably positioned in outside outer tube 20, squeezing into embryo to make embryo transfer course quantization Before tire, the feature and needs that doctor can be different according to each individual determine the depth for needing to squeeze into embryo transplanter, so Afterwards, indicating ring 21 is slided into predetermined position, when squeezing into human body, doctor can observe indicating ring 21 in real time, when indicating ring 21 When being moved to cervix opening, that is, stop squeezing into, to guarantee that the depth of squeezed into embryo transplanter is the depth predefined, such as This, that is, efficiently solve existing embryo transplanter and fully rely on the defect that doctor's experience is squeezed into, improve and squeeze into embryo The accuracy of process, and then can be improved transplanting success rate, while mitigating patient's discomfort.

It, can also be in outer tube in order to which the process for enabling embryo transplanter to squeeze into human body further quantifies in the utility model 20 setting scales, to assist the indicative function of indicating ring 21.

In order to make indicating ring 21 play best indicative function, in the utility model, the width of the indicating ring 21 is significantly big In the width of the cervix opening of the human body to be injected, also, the material with great friction coefficient, such as rubber may be selected in indicating ring 21 Glue is made, and slides back and forth outside outer tube 20 to avoid indicating ring 21, influences the accuracy of injection process, this is art technology Personnel are readily comprehensible, and the utility model is not added to repeat.

Please refer to shown in Fig. 1 and Fig. 3, the syringe 30 of the utility model is connected to liquid taking port 11 of grafts 10 Point, for assisting grafts 10 to draw embryo and squeezing into embryo, syringe 30 provided by the utility model include ear washing bulb 31 and Graded tube 32, wherein the both ends open of graded tube 32 communicates, and lower opening is for being inserted into the liquid taking port of grafts 10, top Opening for ear washing bulb 31 for being inserted into；Also, graded tube 32 is formed by eating transparent soft silica gel, and external equipped with scale, with side Just the position for the embryo for sucking and injecting is read, in order to facilitate the company between graded tube 32 and ear washing bulb 31 and grafts 10 It connects, the lower ending opening of graded tube 32 and upper end opening are respectively provided with trapezoidal, and each trapezoidal top side by the utility model It is long to be greater than lower section side length, in the liquid taking port to facilitate insertion grafts, while facilitating the insertion of ear washing bulb 31.Also, it considers 32 upper opening of graded tube is inserted into for ear washing bulb 31, is easy to be burst by ear washing bulb 31, in the utility model, by the upper of graded tube 32 Trapezoidal two that end opening is presented while side length be disposed as be less than lower ending opening presented trapezoidal two while side It is long, so that the opening of 32 top of graded tube and the periphery wall of graded tube 32 have certain interval, to protect graded tube 32 Upper opening.

The beneficial effects of the utility model are as follows:

1, by the setting of indicating ring outside outer tube, the depth that embryo transplanter squeezes into human body is accurately controlled, is avoided Embryo transfer process is completely dependent on the defect of doctor's experience, makes embryo transfer operation quantization, alleviates the discomfort of patient body.

2, by the setting of graded tube, the volume of injected embryo is accurately controlled, can avoid embryonal vaccination volume not When cause embryo transfer to fail the case where.

3, the setting of certain angle is presented by grafts tail portion and middle section part, can convenient in inverted microscope or Embryo is drawn under stereoscope manually.

Although the utility model is illustrated using above-mentioned preferred embodiment, so it is not intended to limit the utility model Protection scope, anyone skilled in the art are within the spirit and scope for not departing from the utility model, relatively above-mentioned implementation Example carries out various variations and still belongs to the range that the utility model is protected with modification, therefore the protection scope of the utility model is with right Subject to claim is defined.
