Description
【0001】[0001]
本考案は、超音波診断装置を使用して家畜、おもに牛、馬の卵巣を映像として 写し出し、その映像を見ながら卵子を採卵する家畜用採卵装置に関するものであ る。 The present invention relates to a livestock egg-collecting apparatus that uses an ultrasonic diagnostic apparatus to project ovaries of livestock, mainly cows, and horses, and collects eggs while watching the images.
【0002】[0002]
現在、通常複数個の受精卵を採取する方法として雌牛にホルモン剤を投与して 過剰排卵を誘起し、子宮頸管を通して還流液を子宮内に送り込み、その還流液と 一緒に排卵される卵子を採取する方法と、屠殺場で屠殺して牛や馬等の卵巣から 未受精卵を採取し、体外培養して成熟卵にする方法とがある。 Currently, as a method of collecting multiple fertilized eggs, hormones are usually administered to cows to induce superovulation, and reflux fluid is sent into the uterus through the cervical canal to collect ovulated eggs together with the reflux fluid. There is also a method of slaughtering the unfertilized eggs from the ovaries of cattle, horses, etc. by slaughtering them at a slaughterhouse and in vitro culturing them to mature eggs.
【0003】[0003]
しかし、前者ではホルモン剤等の投与で強制的に過剰排卵させる為、卵巣反応 が弱まり、継続的に排卵誘起ができず、経済的にも効果的な採卵が行えない。 また、後者では、雌牛を特定することができない為、高品質牛の改良に役立て られない。 However, in the former case, ovarian reaction is weakened because ovulation is forcibly superovulated by the administration of hormones, etc., and ovulation cannot be induced continuously, and economically effective egg collection cannot be performed. Also, the latter cannot be used to improve high quality cows because the cows cannot be identified.
【0004】 本考案は、上記従来事情に鑑みてなされたもので、その目的とする処は、超音 波診断装置を使用して生体(正常体)から直接採卵することができる家畜用採卵 装置を提供することにある。The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to collect an egg directly from a living body (normal body) using an ultrasonic diagnostic apparatus. To provide.

(Claim 1) After inserting the hand from the rectum to artificially draw the ovary to the vicinity of the innermost part of the vaginal wall, insert the egg-collecting device into the vagina and bring the ultrasonic probe into contact with the vaginal wall. Sound waves are transmitted from the ultrasonic probe in the direction of the ovary, and the ovary with small follicles is captured as an image. While observing the image, the egg collection needle inside the protective tube is operated from the outside to invade the vaginal wall to enter the small follicle formed in the ovary, and the capture device is activated to collect the egg from the tip of the egg collection needle. (Claim 2) In the same manner as in Claim 1, a small follicle of the ovary is captured as an image, and an egg-collecting needle is inserted into the vaginal wall to enter the small follicle, and then a reflux device and a reflux liquid are discharged. The suction device for sucking the vesicles is operated together to suck the small follicles together with the reflux liquid from the suction flow channel together with the reflux generation liquid sent from the discharge flow channel. (Claim 3) The egg collection needle is protected from various bacteria in the vagina.

本考案は以上のように構成したから、下記の利点がある。 (請求項1、2)超音波診断装置で生体(正常体)の卵巣を映像として捕捉しな がら卵巣に出来た小卵胞から採卵する新規な家畜用採卵装置を提供できる。 従って、過剰排卵させる先行方法のように薬液投与等で卵巣への負担をかけず 、生体の健康を損ねるようなこともなく、生体の一定した排卵周期を厳守しつつ 効率的に採卵できる。 (請求項3)膣挿入時に膣内面と接触しないように保護筒で防護された採卵針は 、採卵途中においても一切腟内と隔絶した状態になるから、採卵針に腟内の雑菌 が付着したり、針内にその雑菌が入り込むような虞れもなく、採卵に悪影響を与 えることがない。 (請求項4)採卵針の腟壁から前進が操作する手元で段階的に規制してある為、 針先が映像として捕らえることができなくとも、採卵針針先を堅実に前進させ、 急速に採卵針が動いて卵巣を突き破るようなアクシデントを起こす虞れがない。 (請求項5)延長仮想線上の所定間隔をおいた位置で交差する向きにしている為 、専門技術者の技量によって膣壁に対して前記所定間隔と同等距離まで卵巣を引 き寄せることによって採卵針の卵巣(詳細には小卵胞)到達までの前進距離を確 約でき、憶測に頼らないで手元の操作だけで卵巣に採卵針先端を到達させること ができる。 (請求項6)針先が摩耗したりして交換を余儀なくされる場合でも、取込装置と の連絡を解除し且つセットネジの緊結を解くことで旧採卵針を保護筒後端部の筒 状手元部内に針ホルダーが嵌合した使用形態のまま外せて、更に新しい採卵針を 装着でき、採卵針の交換が頗る簡単で、しかも採卵針の針先を保護筒先端レベル に合わせた正規な位置に確実にセットできる。 Since the present invention is configured as described above, it has the following advantages. (Claims 1 and 2) It is possible to provide a novel domestic egg-collecting device for collecting eggs from small follicles formed in the ovary while capturing an image of a living body (normal body) ovary with an ultrasonic diagnostic device. Therefore, unlike the prior method of superovulation, it does not impose a burden on the ovary by administering a chemical solution or the like, and does not impair the health of the living body, and it is possible to efficiently collect eggs while strictly adhering to the constant ovulation cycle of the living body. (Claim 3) The egg-collecting needle protected by a protective tube so as not to come into contact with the inner surface of the vagina when inserted into the vagina is completely isolated from the vagina even during egg collection, so that various bacteria in the vagina adhere to the egg-collecting needle. Also, there is no risk that the germs will enter the needle and will not adversely affect egg collection. (Claim 4) Since the advance is controlled stepwise from the vaginal wall of the egg collecting needle, even if the needle tip cannot be captured as an image, the egg collecting needle needle tip can be moved forward steadily and rapidly. There is no risk of an accident where the egg collection needle moves and breaks through the ovary. (Claim 5) The egg is collected by pulling the ovaries to the vaginal wall up to a distance equal to the predetermined interval, depending on the skill of a professional engineer, because they are oriented so as to intersect at a predetermined interval on the extended virtual line. The forward distance of the needle to reach the ovary (specifically, the small follicle) can be assured, and the tip of the egg collection needle can be reached to the ovary by hand operation without relying on speculation. (Claim 6) Even if the needle tip is worn out and must be replaced, the old egg collection needle is protected by releasing the connection with the take-in device and unfastening the set screw. The needle holder fits inside the handle, you can remove it as it is, you can attach a new egg collecting needle, it is easy to replace the egg collecting needle, and the needle tip of the egg collecting needle is adjusted to the protective tube tip level. Can be reliably set in position.

The egg collecting needle 12 can be pulled out from the needle holder 52b as it is.
【0022】 次にこの第1実施例の作用を説明する。 生体の排卵周期毎に直腸から手を入れて卵巣300 を膣壁200 奥端近傍まで人為的 に引き寄せ、併行してグリップ機能部32bを握持して膣壁200 奥端に超音波用探 触子1が当接するように膣内に差し入れ、小卵胞が出来た卵巣300 を映像化する 。その時、保護筒22の先端は同様に膣壁200 奥端に当接し且つ採卵針12はその保 護筒22先端と同一レベルにある。 次に映像を見ながら前記所定距離に相当する 前進距離だけ手元部で操作摘み52d-4を操作して段階的に保護筒22内の採卵針12 を前進させ、針先を卵巣300 に生じたその小卵胞に至らしめる。操作摘み52d-4 を操作し膣壁200 を喰挿し且つ段階的に前進させる結果、人為的であっても前進 が急速化することなく針先を卵巣300 のその小卵胞に堅実に到達させる。その後 、ポンプ42bを作動させて貯卵用容器42c、42cに採卵する。Next, the operation of the first embodiment will be described. At each ovulation cycle of the living body, the ovary 300 is artificially drawn to the vicinity of the innermost part of the vaginal wall 200 by inserting a hand from the rectum, and in parallel, the grip function part 32b is grasped and ultrasonic detection is performed on the innermost part of the vaginal wall 200. Insert the child 1 into the vagina so that it abuts and image the ovary 300 with small follicles. At that time, the tip of the protection tube 22 also abuts on the back end of the vaginal wall 200, and the egg collection needle 12 is at the same level as the tip of the protection tube 22. Next, while watching the image, the operation knob 52d-4 was operated at the hand portion by the forward distance corresponding to the predetermined distance, and the egg collection needle 12 in the protection tube 22 was gradually advanced to cause the needle tip to be located on the ovary 300. Bring up the small follicle. As a result of manipulating the operation knob 52d-4 and inserting the vaginal wall 200 and advancing it stepwise, the needle tip can reach the small follicle of the ovary 300 steadily without accelerating the advance. After that, the pump 42b is operated to collect eggs in the egg storage containers 42c, 42c.
【0023】 この実施例の特長は、図示するように、ある掛止孔52c-1に操作用掛止凸部52 dが掛止した状態において採卵針12の針先が保護筒22の先端と同一レベルに位置 している為、掛止孔52c-1間隔を前記所定距離と一致させておけば上位の掛止孔 52c-1に掛止するように一段だけ掛止用操作凸部52cを移動させることで簡単に 採卵針12針先を卵巣300 に出来た小卵胞に到達できることと、貯卵用容器42cが 2連式である為、ポンプ42bへの卵子の進入を防止できることである。 また、掛止孔52c-1は、母体の大きさや卵巣300 を引き寄せる専門技術者の技 量のある、なしに適応できるように前記所定距離2cmの範囲の中でピッチ間隔 を可変して多く設けてあっても構わない。As shown in the figure, the feature of this embodiment is that the needle tip of the egg collecting needle 12 is located at the tip of the protective tube 22 in a state where the operation hooking convex portion 52d is hooked on a hooking hole 52c-1. Since they are located at the same level, if the spacing of the latching holes 52c-1 is made to coincide with the above-mentioned predetermined distance, the latching operation protrusions 52c will be raised only one step so that the latching holes 52c-1 will be latched in the upper latching holes 52c-1. By moving the egg collection needle 12 needle tip can easily reach the small follicle formed in the ovary 300, and since the egg storage container 42c is a double type, it is possible to prevent the invasion of the egg into the pump 42b. In addition, many hook holes 52c-1 are provided by varying the pitch interval within the above-mentioned predetermined distance of 2 cm so that it can be adapted without or with the size of the mother's body and the skill of a specialist who draws the ovaries 300. It doesn't matter.
