この発明は、牛などのような動物の子宮内に人工受精卵
を移植するために用いられる受精卵移植装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fertilized egg transplantation device used for transplanting an artificially fertilized egg into the uterus of an animal such as a cow.
近年、牛などの子宮内に人工受精卵を移植する方法が普
及しつつあり、従来一般には、注射針の様なものの先端
に人工受精卵をピストンによって吸引し、その注射針を
牛などの腹の外から穿刺して、針先を子宮に到達させて
いる。In recent years, the method of implanting artificially fertilized eggs into the uterus of cows and other animals has become popular. Conventionally, the artificially fertilized eggs are sucked into the tip of a hypodermic needle using a piston, and the needle is inserted into the abdomen of a cow or other animal. A puncture is made from outside the uterus, and the needle tip reaches the uterus.
このとき、注射針が子宮に到達したかどうかの確認は、
外陰部から内視鏡を挿入して、視認により行われる。At this time, to check whether the injection needle has reached the uterus,
This is done by inserting an endoscope through the vulva and visual inspection.
しかし、注射針を腹の外から穿刺して針先を子宮内に正
確に到達させるのは非常に難しくて高度な技術を必要と
し、失敗する場合も少なくない。However, it is very difficult to puncture an injection needle from outside the abdomen and accurately reach the needle tip into the uterus, requiring advanced techniques and often resulting in failure.

かし、複数の牛に受精卵を移植する際に、作業者が現場
でこれをくり返して行うことは多大の労力を必要とする
と同時に、牛舎などでこのような作業を行うことは、は
なはだ不衛生である。In addition, each time it is necessary to confirm with a microscope whether a single fertilized egg has been properly placed in the injection needle. However, when implanting fertilized eggs into multiple cows, it requires a great deal of labor for workers to repeat this process on site, and at the same time it is extremely unsanitary to perform such work in cow sheds. It is.
この発明は、そのような従来の欠点を解消し、受精卵を
容易かつ正確に子宮内に移植することができ、しかも衛
生的な受精卵移植装置を提供することを目的とする。It is an object of the present invention to provide a hygienic fertilized egg transplantation device that can eliminate such conventional drawbacks and easily and accurately transplant a fertilized egg into the uterus.

４ａが受精卵収容チューブ２の前方へ押し出される。In the operating section 20 configured in this manner, the operating core bar 9 can be moved forward and backward within the insertion tube 1 by operating the thumb rest 25 in the direction of the arrow M. As a result, when the tip of the manipulating core bar 9 pushes the piston rod 6 in the fertilized egg storage tube 2, the glycerin layer 4a in which the artificially fertilized eggs are stored is partitioned off at both ends by the air layer 3. All the glycerin layers 4a are reliably pushed out to the front of the fertilized egg storage tube 2 without being mixed with the glycerin layer 4b in which fertilized eggs are not accommodated.
なお、第４図中のＡは操作ストロークであり、ガイドパ

る。Therefore, when the connecting tube 32 is pushed into the fertilized egg accommodation tube 2, the slit 31 closes slightly due to elastic deformation as shown in FIG. The connecting tube 32 and the fertilized egg storage tube 2 are maintained in a connected state by the spring force that tends to expand them to their original state. Then, by strongly pulling the fertilized egg storage tube 2 toward the tip, the fertilized egg storage tube 2 is removed from the connecting tube 32, as shown in FIG.

The endoscope 11 is inserted into an auxiliary insertion tube 12 that is inserted straight through an external opening 82 into a cervix 81 of a cow or the like. By using the insertion auxiliary tube 12 in this way, the endoscope 1
1 can be inserted straight into the hard cervical canal 81 without damaging it.
