Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fertilized egg transplantation device integrated with endoscopic forceps for transplanting fertilized eggs into livestock.

[Conventional technology]

Conventional fertilized egg transplanters, as shown in Japanese Patent Publication No. 179057/1982, include grasping forceps that pinch and fix the transplanted part of the uterine horn during transplantation, and a transplant that injects and transplants the fertilized egg into the uterine horn. The transplantation process was carried out using a transplanter, which was passed through the respective conductive channels provided in the endoscope, and the transplantation site was fixed using grasping forceps.

[The problem that the idea aims to solve]

According to such conventional technology, it is very difficult to operate by pinching and fixing the transplant site in the uterine horns with grasping forceps while observing the transplant site with an endoscope, and then guiding the transplant device there and injecting the fertilized egg. There were problems in that it was complicated and difficult to perform, and it was difficult to reliably inject the fertilized egg into the uterine horns.

[Means to solve problems]

The present invention consists of two tubes integrated into the main body, a gripping forceps attached to the tip of one of the tubes, a wire for operating the gripping forceps passed through the tube, and the wire connected to the tube. The main body is operated using an operating tool installed at the rear end, and a pipe with a transplant needle attached to the tip is passed through the other tube, and the main body is inserted through the tube of the endoscope inserted into the body. It is characterized by being inserted into the body.

[Effect]

According to the above configuration, the main body is inserted into the body through the tube part of the endoscope, and the fertilized egg injection site is fixed by grasping the vicinity of the fertilized egg injection site with grasping forceps, and the fertilized egg injection site is fixed after the pipe is inserted. A fertilized egg syringe is connected to the end of the transplant needle, and the fertilized egg can be reliably transplanted to the fertilized egg injection site.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a side view showing the embodiment, Fig. 2 is a partially enlarged side view with the grasping forceps opened, and Fig. 3 is a side view of the endoscope with the forceps-integrated fertilized egg transfer device attached. In the figure, 1 is the main body, which consists of two upper and lower tube bodies 2 and 3.

At the tip of the tubular body 2, there are grasping forceps 4 that open in a direction that does not interfere with the tubular body 3. An operating wire for operating the grasping forceps 4 is passed through the tube and connected to an operating tool 5 at the rear end. By operating the operating tool 5, the gripping forceps 4 can be opened and closed. Reference numeral 6 denotes an adjuster ring for fixing the movement of the operating wire, thereby making it possible to maintain the gripping forceps 4 in an open state at a desired angle.

A stainless steel pipe 8 having a transplant needle 7 at the tip is passed through the tube of the tube body 3, and the rear part of the pipe 8 protrudes from the rear end of the tube body 3, and a connecting part 9 is provided at the rear end. . Reference numeral 10 designates an adjuster ring for fixing the pipe 8, which allows the pipe 8 protruding from the tip of the tube body 3 to be held in that state.

Reference numeral 11 denotes a transport pipe that can be connected to the connecting portion 9, and has a connecting portion 12 at the rear end.

Reference numeral 13 denotes a syringe for injecting the fertilized egg together with a storage solution into the transport tube 11. When the fertilized egg is injected from this syringe 13, the fertilized egg can be injected from the transplant needle 7 at the tip of the pipe 8.

Reference numeral 14 denotes an endoscope, which has an eyepiece section 15 and a tube section 16 into which the main body 1 is inserted.

The operation of the embodiment with the above configuration will be explained below.

When the estrous cycle of a livestock recipient is in a fertilizing cycle, for example, in the case of a pig, the pig is placed in a supine position and punctured with a trocar on the midline below the navel or several centimeters to the left and right from the midline. Make a hole. This position corresponds exactly to the uterine horns. Therefore, by inserting an endoscope into this perforation hole, it becomes possible to search for the transplantation site of the uterine horn using the endoscope, as will be explained below.

Further, another hole is bored in the vicinity of the above-mentioned hole with a trocar, and the operating rod is inserted through this hole.

Therefore, while observing through the eyepiece 15 of the endoscope 14, I searched for the ovary using the operating rod.
Locate the uterine horns a few centimeters away from the tubal-uterine junction.

Therefore, the main body 1 is inserted into the tube part 16 of the endoscope 14, the grasping forceps 4 are placed near the fertilized egg injection site, and the operating tool 5 is operated to grasp the fertilized egg injection site. The injection site is fixed and maintained in that state by the adjuster string 6.

The transplant needle 7 is inserted into the thus fixed fertilized egg injection site by manipulating the rear part of the pipe 8, and it is confirmed whether the transplant needle 7 has reliably penetrated the uterine horn wall and reached the inside. For this purpose, inject approximately 10μ of the preservation solution using the syringe 13.

As a result, when the transplant needle 7 does not penetrate the uterine horn wall and its tip remains within the uterine horn wall, the endoscope 14 can confirm the expansion of the uterine horn wall, and in that case, By further pushing the rear part of the pipe 8, the tip of the transplant needle 7 can penetrate the wall of the uterine horn. On the other hand, if the transplant needle 7 penetrates the wall of the uterine horn and reaches the uterine horn, it can be confirmed that there is no expansion and the needle has penetrated.

Once it is confirmed that the transplant needle 7 has penetrated the uterine horn wall, the preservation solution containing the fertilized egg is injected into the pipe 8 using the syringe 13, and the fertilized egg is transferred from the transplant needle 7 into the uterine horn. Can be transplanted.

In the above embodiment, the tubular bodies 2 and 3 are arranged vertically, but it is not necessarily limited to this. The vertical arrangement of the tubular bodies 2 and 3 may be reversed, or they may be arranged horizontally or diagonally. The opening/closing direction of the grasping forceps may be determined as appropriate depending on the arrangement.

[Effect of idea]

According to the present invention described above, two tubular bodies are integrated to form a main body, a grasping forceps is attached to the tip of one of the tubular bodies, and a wire for operating the grasping forceps is passed through the tube. The wire was operated by an operating tool provided at the rear end of the tube, and a pipe with a transplant needle at the tip was passed through the other tube.
The main body is inserted into the body through the tube of an endoscope inserted into the body, and the fertilized egg injection site is fixed by grasping the area around the fertilized egg injection site with grasping forceps, and the rear end of the pipe is fixed. A fertilized egg syringe is connected to the fertilized egg syringe, and the fertilized egg is transferred to the fertilized egg injection site using a transfer needle. It has the effect of making work easier.
