Description
Technical field
The invention belongs to the technical field of embryo transfer, is related to the component of cervical dilatation, is used for more particularly, to one kind
The component of cervical dilatation before ox embryo transfer.
Background technology
Ox embryo transfer is a new technology to grow up after artificial insemination, it has also become it is excellent to expand outstanding dam
The important means of gene.At present, the development of ox embryo transfer technology is ripe, and transplanting success rate is also basicly stable.China domestic animal
Embryo transfer technology, especially ox embryo transfer technology develop comparatively fast in recent years, possess commercial application condition substantially, development
Have a extensive future.The high-tech enterprise in all parts of the country based on embryo transfer technology also have developed rapidly at present, ox embryo transfer technology
Promote existing certain scale and obtain good economic benefit, its industrialization has stepped the first step.The popularization of ox embryo transfer technology
Breeding potential to giving full play to excellent cow, the excellent female gamete of utilization and extention, accelerate drove improvement etc., there is important reality
Border productive value, also play an important roll in the research of Animal genetics and breeding physiologic.
Ox embryo transfer technology has two kinds of operation transplantation method and Nonoperative method, it is existing it is commonly used be it is simple to operate,
The small Nonoperative method of cost.The tubule that embryo will be housed is put into apparatus --- the ox embryo transfer gun of embryo transfer, by straight
Intestines hold embryo transfer gun by Niu Yindao, cervix, into uterus, be put into cornua uteri deep as much as possible, can so obtain
To ideal pregnancy rate.When actually carrying out graft procedure because cervix is one of important natural screen of ox reproductive system
Barrier, it is one of key point for improving transplanting success rate transplanting rifle is smoothly through cervix and then cornua uteri deep.Ox
Cervical length and fineness degree due to cattle breeds, age and calving number etc. it is different and difference is very big, both made same kind
Difference between the Different Individual of ox is also very big, and from 5 to more than 20cm, external diameter fineness degree diameter is length from 1 to more than 7cm
One pipeline formed by muscular wall, it is harder, close after oestrus relatively tight, slightly relax during heat.Cervix is cloudy
Road portion protrudes from intravaginal about 2cm, there is radial ridges on mucous membrane, claims the external os of vervix, has one to be led to by uterus in cervix
Toward the pipeline of vagina, claim canal of uterine cervix, it is the door in uterus, is the passage that sperm enters uterus and fetus output.In uterus
In neck tube, there is the crescent gauffer of 2~5 transverse directions, be fitted together to each other, make canal of uterine cervix curl.In canal of uterine cervix close to son
The one end in palace, there is one section of flourishing sphincter, close canal of uterine cervix tighter, claim internal cervical orifice.Two inside and outside cervix muscle
Layer intersection has vascular lamina, so bleeding is many during cervical rupture.Cervix mucous membrane has two kinds of epithelial cells, and one kind is tool
There is the column ciliated epithelial cell of motile cilium, another kind is not ciliate column secretory epithelial cells.In different physiology shapes
Very greatly, in the gestational period and luteal phase, cervix closing is very tight, and secretory activity weakens for cervix change under state, mainly prevents outer
Thing invades, and shields.Under heat state, cervix relaxation, secretion increases, and is created conditions for breeding.In childbirth,
Cervix, which can be expanded to, is enough to make fetus by the way that amplitude of variation is very big.
Used recipient cattle is typically chosen the less big local ox of individual during domestic ox embryo transfer, according to data report
Road：Recipient cattle is done using the young ox for not producing calf and the ox fond of food that is not salty for producing one or two tire, conception rate can be higher, but these oxen one
As cervix it is more elongated, embryo transfer time is usually that now cervix is closed tighter the 7-8 days after ox heat, transplants time shift
It is more difficult by cervix to plant rifle, especially to operating unskilled personnel, more even to operating very skilled personnel
Also there is the situation that being difficult to, embryo transfer gun is passed through cervix and inserted in uterus for young ox and grade, it has to make with thicker
Expansion metal rod disclose expansion repeatedly, be particularly easy to cause the bleeding lesions of cervix, and then trigger cervix and inflammation of uterus, no
Son transplanting success rate is only influenceed, is also easy to influence ox reproductive system health.Both after using dilator bar, also there are indivedual cattle uterus necks
Carefully, firmly, still embryo can not be inputted by cervix.
The content of the invention
Regarding the issue above, the present invention provides a kind of component for cervical dilatation before ox embryo transfer,
Make to enter uterus more easily by cervix during embryo transfer, improve the success rate of embryo transfer, reduce because of embryo transfer
Genital system infection rate caused by and and the stress reaction of ox, and there is the advantages of easy to operate.
To reach above-mentioned purpose, present invention employs following technical proposal：This is used for cervical dilatation before ox embryo transfer
Component, including the outer sleeve body with inner chamber, is provided with bracket assembly in described outer sleeve body, is set on described bracket assembly
