Embodiment 1

[0038] An embryo transfer tool such as figure 1 As shown, it includes a transplanted outer tube 1, an outer tube steel wire 2, a transplanted inner tube 3 and a stainless steel guide wire 4 with a curved front end (the specific shape and structure are as follows: Figure 5 shown), the transplanted inner tube 1 is set inside the transplanted outer tube 3, the described outer tube steel wire 2 is set inside the transplanted outer tube 1, and the stainless steel guide wire 4 with a curved front end is set inside the transplanted inner tube 3 .

[0039] like figure 2 As shown, the transplanted outer tube 1 includes a catheter 5 and a joint 6, the transplanted outer tube 1 is 277.00 mm long, the catheter 5 is 250.00 mm long, the outer diameter of the catheter 5 is 2.00 mm, and the inner diameter is 1.65 mm. The joint 6 is 35.00 mm long, and its inner diameter gradually decreases from the place far away from the catheter to the place near the catheter. Specifically, the inner dia...

Embodiment 2

[0043] Use the embryo transfer tool to transfer goat embryos, as follows:

[0044] (1) According to the superovulation time of the donor ewe, the recipient ewe is subjected to simultaneous estrus;

[0045] (2) Disinfect the recipient ewes before transplantation, expose the cervix of the sheep with a vaginal dilator, and wipe off the cervical mucus;

[0046] (3) Scrub the cervix with culture fluid;

[0047](4) insert the outer tube steel wire 2 into the transplanted outer tube 1, and insert the transplanted outer tube 1 into the uterus through the cervix of the goat; the transplanted outer tube 1 enters the uterus and stops immediately to ensure that the endometrium is minimally damaged; if If the cervix of the ewe is relatively tight, or the curvature is more severe, the cervix is ​​first passed through the cervix with the outer tube steel wire 2, pulled out immediately through the cervix, and then inserted into the uterus with the transplanted outer tube 1.

[0048] (5) The...

Abstract

The invention relates to an embryo transplantation tool and an application, wherein the embryo transplantation tool is constituted of a transplantation outer tube, an outer tube steel wire, a transplantation inner tube and a stainless steel guide wire with a bent front end. The transplantation outer tube has plasticity, wherein the front end is equipped with an accurate scale, so the embryo transplantation tool is suitable for a bent cervix and can measure an insertion depth into an uterus; and the transplantation inner tube is soft, brings small damages to an endometrium and has no embryo toxicity, and the rear end is equipped with the scale which can objectively reflect the length of the transplantation inner tube outside the outer tube. The tool can be used to transplant a goat embryo, reduce wounds caused by a goat embryo transplantation operation, reduce tissue adhesion and increase use efficiency of a receptor.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to an embryo transplantation tool and its application. Background technique [0002] my country is a big agricultural country, but the production efficiency of animal husbandry has been low for a long time. An important reason for this situation is due to the shortage of good breeding stock. How to realize the popularity of fine varieties, one of the ways is to adopt superovulation and embryo transfer technology. However, the embryo transfer of high-quality breeding stock is now mainly carried out by surgical methods (laparoscopic surgery or direct laparotomy). After using 1-2 times, it must be eliminated due to pelvic adhesion or infection, which reduces the utilization efficiency of the recipient sheep and also increases the production cost. Using the embryo transfer tube to perform intrauterine embryo transfer through the cervix is ​​non-invasive, the sheep recov...
