Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a tissue specimen cassette lid assisting tool that allows the lid of the tissue specimen cassette to be easily removed without touching the tissue specimen cassette.

[Prior art and its issues]

In order to perform a histopathological examination, it is necessary to convert the collected tissue into a tissue specimen according to a certain method. A so-called tissue specimen cassette (hereinafter simply referred to as a cassette) is used as a device for this purpose. A cassette consists of a cassette base with an open top and a bottom surface having a large number of through holes, and a plate-like lid body which is detachably attached to the opening of the cassette base and also has a large number of through holes. The procedure for preparing a tissue specimen using a cassette is as follows. ■ Place the sample into the cassette base, attach the lid, and immerse the cassette in a chemical solution to dehydrate the water in the tissue of the sample. (2) Remove the cassette from the chemical solution and immerse it in molten paraffin, which is an embedding agent, to allow the paraffin to penetrate into if 4% of the sample. ■ Pull up the cassette) from the molten paraffin, remove the lid and take out the sample from inside. 8. Embedded U + Kotazu with about half of melted paraffin in it. ■ Place the cassette base on the top of the embedding dish with the bottom facing down, and fill it with molten paraffin through the permeation hole to embed it in the supine position. ■ When the paraffin is cooled and solidified, the cassette base and the paraffin block in which the tissue is embedded are left to rest. The paraffin block is then separated from the embedding dish. Note that the cassette base serves as a base when attaching a paraffin block to a micro-me (thin slicer). In step (3) above, to remove the lid from the cassette base, hold both sides of the cassette base between your thumb and middle finger, and hook your index finger onto the claw at the rear of the lid to remove it. However, this conventional method had the following problems. That is, when removing the lid with your fingers, the molten paraffin adheres to your fingers, making it hot and difficult to remove. Also, if paraffin + or I gets on your fingers, it hardens and becomes dirty, so you need to wipe it off quickly, but it is a pain to wipe it off every time. [Object of the present invention] An object of the present invention is to make it possible to easily remove the lid of a cassette in the tissue sample preparation process using a bottle set or the like without touching the cassette. [Configuration of the present invention] In order to solve the above-mentioned problems and achieve the objectives, the configuration of the present invention, which is Hf15, is as follows. That is, the present invention includes a base, the base has a stop part,
Fit facing the stop part! A mounting table device is provided, and the mounting table piece is located at a position where the claw at the rear of the lid of the cassette is placed on the top when the front end of the bottom of the cassette is brought into contact with the stop portion and the cassette is inserted. and f
ll! This is a lid opening aid for tissue sample cassettes, and the height of the neck stand piece is set so that it rises slightly from the rear bottom surface of the cassette or the installation surface when it is inserted. The base has a shape that allows it to be stably installed on a horizontal installation surface, and is, for example, rod-shaped or plate-shaped. The frame-shaped material may be made of, for example, a metal wire, or a heavy casting may be used to increase stability. Further, in order to prevent the molten paraffin dripping from the cassette from accumulating, the base portion may be provided with an outflow portion for allowing the molten paraffin to flow out of the frame. The structure of the outflow portion is not particularly limited; for example, a member may be bent to form a gap between it and the installation surface, or a structural portion may be provided. Note that a flat plate-shaped workbench may be used as the platform, and a stop portion and a mounting table piece may be provided at arbitrary locations on the platform. [Example] The present invention will be described in more detail based on an example shown in the drawings. FIG. 1 is a perspective view showing a first embodiment. The lid opening aid has a base part 1 which is a frame made of metal wire. The stand ri1's i is rectangular in plan view and consists of a short side member 11.12 and a long side member 13.14. The other short side member 11 serves as a stop part 2 against which the front end of the bottom of the cassette comes into contact when inserting a cassette 1-9, which will be described later. ,
This makes it easy to insert the cassette 9. Further, a mounting table piece 4 is erected at the center of the other short side member 12, and the top thereof is in contact with the mounting section 5 2J. The mounting table piece 4 connects the bottom front end side of the cassette 9, which will be explained later, to the stop part 2.
When the cassette 9 is inserted, the cassette 9
The claw portion 94 at the rear of the lid body 92 is disposed at a position where it is placed on the placing portion 5. Further, the height of the mounting table piece 4 is set so that the rear bottom surface of the cassette base body 91 is slightly raised from the installation surface when the user is not busy. The long side members 13 and 14 are formed with their central portions slightly curved upward in order to provide a gap between them and the installation surface. This prevents molten paraffin from accumulating on the inside of the table 1. Incidentally, reference numeral 6 is a stabilizing member for stabilizing the base portion 1. (Function) Figure 2 shows the state in which the cassette is inserted into the lid opening aid 6
．． The fourth perspective view and FIG. 3 are explanatory diagrams showing the method of opening the lid. The cassette 9 is made of plastic deck and consists of a cassette base 91 and a lid 92. The lid body 92 is provided with a large number of transmission holes 93, and a claw portion 94 is formed in the center of the rear side. The lid body 92 is latched from the front with a latching claw (not shown),

Ru. Then, as explained in (e) and (2) Steps for returning to the steps for creating the textile marker, the sample can be prepared without removing the sample from inside. How to use the lid opening aid is as follows. 0] Place the lid opening aid on workbench B, which is the top surface. 2. As shown in FIG.
is placed on the mounting portion 5 of the mounting table piece 4 and fitted into the lid opening aid. At this time, the bottom surface of the rear side of the cassette 9 is slightly raised from the workbench B. Note that this operation is performed indirectly using a pincer l-P or the like so that the molten paraffin does not get on your hands. ■ As shown in Fig. 3, when the approximately central part of the lid body 92 is pushed in the direction of the arrow with the pincer l-P, the central part of the lid body 92 deforms downward, and the reaction causes the hinge parts 95 and 96 to latch. The lid 92 is released and removed from the cassette base 91. At this time, the molten paraffin that was in the cassette 9 (=J) and flowed onto the workbench B flows out of the workbench 1 through the gap S between the long side members 13, 14 of the workbench B and the workbench B. It flows out and does not accumulate inside, and the molten paraffin does not splash due to contact between the bottom surface of the cassette base 91 and the workbench B when the hinge parts 95 and 96 are released. All you have to do is pick it up and take out the sample 1' inside the cassette base 91. Fig. 4 is a perspective view showing the second embodiment.
