Abstract
The utility model relates to an embryo transplantation device which solves the embryo transplantation problems of unreasonable embryo leading, inexact targeting, etc. The utility model is used for the embryo transplantation technology. The utility model comprises an outer sleeve pipe and a transplantation core which are matched with each other, wherein the outer sleeve pipe is provided with a through hole and is in a tubular shape, and the transplantation core can be inserted into the through hole; the head of the outer sleeve pipe is a spherical head with an opening; the transplantation core is provided with a through hole and is in a tubular shape, the outside diameter of the transplantation core is smaller than the inside diameter of the outer sleeve pipe and a conveying element used for sucking or delivering the embryo is arranged at the back end of the transplantation core. The utility model easily and accurately transplants the embryo to the uterus without any pain for grafters, so the utility model has the characteristics of high safety, reliability, etc.
Description
Technical field
This utility model relates to the apparatus of aspect, reproductive medicine field, is mainly used in embryo transfer technology, is a kind of embryo transplanter.
Background technology
In the reproduction field, often relate to the embryo after the germ cell division is transplanted, send into intrauterine and make it to combine closely with parent.If in implanting the uterus process, adopt single body directly the embryo to be sent into, because the embryo who cultivates is generally left in the real pipe of band nutrition, if adopting simply, transplanting wicks into and directly sends in the uterus, on the one hand because the transplanting core is thinner, be difficult to send into, sometimes even can make and transplant core and fracture, can't reach the purpose of transplanting by vagina, on the other hand, will bring the big pain of injury to the parent of accepting to transplant.In addition, general transplanting core all must link to each other with the external device (as similar syringe) of sending into, and it is not too convenient to use.
Summary of the invention
This utility model is to provide a kind of embryo transplanter of being convenient to send into the embryo in embryo transfer at above-mentioned situation, with solve the embryo send into unreasonable, embryo transfer problem such as inaccurate puts in place.
This embryo transplanter includes matching used trocar sheath and transplants core, and its trocar sheath is the tubulose with through hole, and this through hole can make transplants the core insertion wherein, and the head of trocar sheath is the sphere with opening; Described transplanting core is the tubulose with through hole, and its external diameter is less than the internal diameter of trocar sheath, and the end has the conveying member that sucks or send the embryo thereafter.
This embryo transplanter can be sent into the embryo exactly the place, uterus smoothly and not bring any pain of injury to grafter, has characteristics such as safe and reliable.
The drawing explanation
Accompanying drawing is a kind of embodiment sketch map that the utility model proposes.
The labelling implication is as follows among the figure:
1, trocar sheath, 11, head;
2, transplant core, 21, conveying member.
The specific embodiment
Referring to Fig. 1, this embryo transplanter includes matching used trocar sheath 1 and transplants core 2, and its trocar sheath is the tubulose with through hole, and this through hole can make transplants the core insertion wherein, the head 11 of trocar sheath is convenient to align the parent cervix uteri by vagina and is carried out embryo transfer for to have the sphere of opening.Described transplanting core 2 is for having the tubulose of through hole, and its external diameter is less than the internal diameter of trocar sheath, and the end has the conveying member 21 that sucks or send the embryo thereafter, the embryo can be sucked the transplanting in-core by this conveying member and also the embryo can be sent in the parent uterus; Described conveying member can be syringe or has valve piston of function of injection or the like.
Embodiment: the trocar sheath length in the embryo transplanter is 170mm, and external diameter is 2mm, and internal diameter is 1.6mm; It transplants the length of the length of core greater than trocar sheath, and the front end of being convenient to transplant core can extend trocar sheath head opening and carry out embryo transfer, and its length is 230mm, and its external diameter is 1.5mm, and internal diameter is 0.8mm.
Described trocar sheath rearward end has overcoat, is convenient to manipulate.
Claims (2)
1, embryo transplanter includes matching used trocar sheath (1) and transplants core (2), and it is characterized in that: trocar sheath is the tubulose with through hole, and its head (11) is for having the sphere of opening; Described transplanting core (2) is for having the tubulose of through hole, and its external diameter is less than the internal diameter of trocar sheath, and the end has the conveying member (21) that sucks or send the embryo thereafter.
2, embryo transplanter according to claim 1 is characterized in that: trocar sheath length is 170mm, and external diameter is 2mm, and internal diameter is 1.6mm; Its length of transplanting core is 230mm, and its external diameter is 1.5mm, and internal diameter is 0.8mm.
