Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an improvement in the structure of a spoon used in a hollowing device for scraping out the internal organs of a subject such as a human body (for example, a bird).

Background of the Technology In a hollowing device that performs this type of work, a U-shaped spoon made of two parallel members connected at one end by a curved member is used to scrape out internal organs. When processing an object, the spoon is advanced, inserted into the inside of the object from the tail incision, lowered to hold the internal organs, and then withdrawn. He then scrapes out his internal organs. In addition, in the initial state in which the spoon is inserted and lowered as described above, the central portion of the curved portion of the spoon is located above the esophagus and trachea.

Prior Art and Problems Figures 1 and 2 outline the main parts of a conventional hollowing device. FIG. 1 is a front view showing the initial state before scraping out internal organs, and FIG. 2 is a plan view of the same. In the figure, 1 is an object to be processed and 2 is a hollowing device. The hollowing device 2 includes a support base 3 that supports the object to be processed 1, a U-shaped spoon 4, and a drive cylinder 5 that moves the spoon 4 forward and backward in the directions of arrows A and A'.
The base of is connected to the spindle 6 of the drive cylinder 5 via a connecting member 7. Drive cylinder 5
is driven by a drive mechanism (not shown) and can move up and down in the directions of arrows B and B'. Spoon 4 is
Initially, the drive cylinder 5 is moved in the direction of arrow A' from the position shown in the figure. The object to be processed 1 is inserted into the object to be processed 1 by raising it from that position and operating the drive cylinder 5 in that state. After that, by lowering the drive cylinder to the position shown in the figure, the spoon 4
is positioned in the initial state shown in the figure, and in this state the spoon 4 is holding the internal organs 1a of the object to be processed 1.
From this state, when the spoon 4 is pushed back in the direction of arrow A' while holding down the groin 1b of the object 1, the internal organs 1a held by the spoon 4 are scraped out.

However, this conventional scraping of internal organs is performed while the esophagus, gastrotrachea, and lungs are still connected to each other, so the cutting points are irregular and a large tensile force is required, resulting in the internal organs being used for products such as levers. They were often severely damaged, reducing their commercial value. In addition, many workers were required to visually inspect and sort out the extent of this damage.

OBJECT OF THE INVENTION The present invention aims to solve the above-mentioned drawbacks.
It is an object of the present invention to provide a spoon structure of a hollowing device that enables easy and reliable scraping out of internal organs without damaging them.

Structure of the Invention In the present invention, the spoon is formed from a pipe material, and a cutting blade that protrudes from a hole in the center lower surface of the curved portion of the spoon can be returned to the inside of the spoon by being driven by an electromagnetic magnet attached to the spoon. The above object is achieved by arranging the cutting blade to cut the esophagus and trachea by activating the electromagnetic magnet when the spoon is positioned at an initial position and holds internal organs. It's on.

Embodiments of the Invention Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 to 10.

A first example is shown in FIGS. 3 to 6.

FIG. 3 is a plan view showing an outline of the main parts of the hollowing device to which the present invention is applied. The spoon 11 is made of pipe material, and the lower center of the curved portion 12 has a notch for protruding the cutting blade, which will be described later. 13 is formed. An electromagnetic magnet 15 is attached to the end of one parallel member 14 of this spoon 11 via a connecting member 7. Furthermore, a cutting blade 16 is movably provided within the spoon 11. This cutting blade 16
is connected to the plunger 17 of the electromagnet 15 via a rope 18, and is also connected via a rope 21 to the other end of a return spring 20 whose one end is fixed to the other parallel member 19 within the spoon.

Now, when the spoon 11 is inserted into the body to be treated and is in the initial state holding the internal organs, when the electromagnetic magnet 15 is energized and activated, the plunger 17 moves to the right in FIG. The blade 16 is driven against the urging force of the spring 20 and moves to the center of the curved portion 12 as shown in FIG. As shown in FIG. 5 of the side view of FIG. 4, a convex portion 22 is formed on the upper part of the curved portion 12 to face the notch 13, so that the cutting blade 16 that moves as described above can
It engages with this convex part 22 and protrudes downward from the notch 13 to make an incision or cut into the esophagus and trachea of the object located directly below it.

After this work is completed, the operation of the electromagnetic magnet 15 is stopped and the spoon 11 is moved back to scrape out the internal organs, but unlike conventional methods, the esophagus and trachea have been cut or incised before that, so the force required for scraping out is It is small and can be scraped out without damaging internal organs.

FIG. 6 shows the biasing force of the spring 20 and the cutting edge 16.
An example of an adjustment means for adjusting the positioning of is shown. In the figure, 23 is a pipe screw, and 24 is an adjustment nut. The pipe thread 23 is screwed into the end of the other parallel member 19, and one end of the spring 20 is connected to the bottom surface of the pipe thread 23 via a connecting member 25. The adjusting nut 24 is screwed into screws 27 on both sides of the bracket 26, which are provided integrally with the fixed portion of the electromagnetic magnet 15 and pass through the bracket 26. Therefore, by adjusting the pipe screw 23 and the adjusting nut 24, it is possible to adjust the biasing force of the spring 20 and the position of the cutting blade 16.

A second embodiment is shown in FIGS. 7 and 8.

FIG. 7 shows how to install the cutting blade in this example. 31 in the diagram
is a cutting edge.

The cutting blade 31 is fan-shaped, and is similar to the spoon 11.
The spring 20 and the electromagnet 15 are rotatably supported at the center of the curved part of the
It is connected to the plunger 17 of. This cutting blade 3
1 rotates as shown in FIG. 8 when the electromagnetic magnet 15 is activated and protrudes from the notch 13 to cut the esophagus and trachea.

In the case of this example, the length l of the blade portion can be increased to increase the amount of protrusion from the notch 13,
Moreover, it is advantageous because there is no slippage as in the case of the previous example.

In the above description, an example has been described in which the curved portion of the spoon is semicircular, but a spoon 11' having a curved portion 12' having the shape shown in FIG. 9 may also be used.

Further, in order to make the cutting edge larger and increase the stroke, a spoon 11'' may be used which has a large diameter portion 30 larger than the pipe material in the center of the curved portion, as shown in FIG.

Effects of the Invention As described above, according to the present invention, the esophagus and trachea can be cut using the cutting blade provided in the spoon before scraping out the internal organs, and the internal organs can be scraped out in this state. Therefore, it is possible to eliminate internal organ damage, which has been a problem in the past, and it is also possible to reduce work costs by omitting the conventionally required visual inspection of internal organs.
