Description

  The present invention relates to an embedding tray for preparing a histopathological specimen, and more particularly, an embedding tray for preparing a histopathological specimen that can accommodate paraffin block adherents such as cassettes of different sizes in a single embedding tray. About.

  Conventionally, as an embedding tray for preparing this kind of histopathological specimen, it comprises a peripheral support part and an accommodating part, and in the tray for creating a paraffin-embedded or frozen-embedded block of a histopathological specimen in the accommodating part. A tray for preparing a histopathological specimen is known in which the shape of the accommodating portion is left-right asymmetric (see, for example, Patent Document 1).

The embedding dish for carrying out the embedding process for casting the specimen with a casting material such as paraffin has a cavity into which the casting material is injected, and the cavity stands on the bottom wall and the periphery of the bottom wall. The cavity has a cavity lower part on the bottom wall side and a cavity upper part located on the cavity lower part, and surrounds the cavity lower part of the side walls. The angle α formed between the inner surface of the lower side wall and the inner surface of the bottom wall is greater than the angle β formed between the inner surface of the upper side wall of the side wall surrounding the cavity and the inner surface of the bottom wall. An embedding dish characterized by being small has been reported (for example, see Patent Document 2).
Japanese Utility Model Publication No. 3-10245 (FIGS. 1 and 2) JP 2003-106963 A (FIGS. 2 and 3)

  For the former tray, the shape of the container is asymmetrical, so that the right and left of the slice obtained by slicing the paraffin block embedding the specimen with a microtome can be clearly distinguished. And increase the reliability of the inspection results.

  In addition, the latter embedding dish is formed so that the shape of the paraffin block is approximately a prismatic shape by reducing the angle formed with the bottom wall of the side wall at the bottom of the cavity so that the paraffin block is shaped prior to slicing the paraffin block. The process of removing and shaping unnecessary paraffin from the block is omitted to reduce work man-hours and work time.

  By the way, in general, the paraffin block is prepared by attaching paraffin embedding the specimen to the bottom of the cassette. The size of the cassette, which is the paraffin block attachment body, varies depending on the type and size of the specimen to be embedded. in use. Furthermore, as described in Japanese Utility Model Laid-Open No. 3-10245, embedding rings and cryostats (trade names) are also used as paraffin block adhering bodies in the same manner as cassettes. There are also various sizes of cryostats.

  However, in the conventional trays and embedding dishes (hereinafter referred to as embedding trays including both), since the size of the accommodating portion or the cavity is constant, for example, a paraffin block is attached and integrated. If the cassette size is different, the embedding tray can no longer cope with it. As a result, it is necessary to prepare many different embedding trays according to the size of the cassette. Since it is necessary to select and use an appropriate embedding tray, the work of creating a vivid specimen is complicated and not only the workability is remarkably lowered, but also the cost of the embedding tray is increased due to an increase in mold cost. In addition, product management and inventory management of various embedding trays must be troublesome. Furthermore, a large space is required for transportation and storage, and the efficiency of transportation and storage is low.

  In view of such circumstances, the present invention eliminates the drawbacks of the prior art described above, and is a package that can cope with various types of cassettes, embedding rings, and other paraffin block attachments by preparing only one type of embedding tray. A buried tray is provided.

  The present invention has been made in order to achieve the above object, and claim 1 of the present invention comprises a paraffin storage portion formed of a rectangular container and a mounting portion of a paraffin block adhering body provided on the periphery thereof.

  According to claim 2 of the present invention, the placement part A of the paraffin block adhering body is provided in a step shape along the periphery of the paraffin storage part, and one or two front sides of two opposing sides are provided. 2. The pathology according to claim 1, wherein a placement part B of at least one paraffin block adhering body is provided at a position lower than the placement part A in the placement part A. Includes an embedding tray for preparation of tissue specimens.

  A third aspect of the present invention includes an embedding tray for preparing a histopathological specimen according to the first or second aspect, wherein the shape of the paraffin container is asymmetric.

  The embedding tray for pathological examination specimen preparation of the present invention is provided with at least two mounting portions for paraffin block adhering bodies such as cassettes, so that one type of embedding tray adheres to paraffin blocks of various sizes. Can deal with the body.

  Therefore, when preparing paraffin blocks, it is not necessary to prepare various embedding trays of different sizes in advance, and to select and use the embedding tray according to the size of the paraffin block adherent such as a cassette. The property is greatly improved.

  In addition, since one type of embedding tray can handle various types of paraffin block adhering bodies, not only can the mold cost be saved and the embedding tray can be provided at low cost, but also product management and inventory management become easy. Also, the space for transportation and storage is small.

  An embedding tray (hereinafter simply referred to as an embedding tray) for preparing a pathological specimen according to the present invention comprises a paraffin storage portion made of a rectangular container and a placement portion for a paraffin block adhering body provided on the periphery thereof. , At least two placement parts are provided.

  The embedding tray of the present invention is made of a heat-resistant material that can withstand liquid (molten) paraffin, and examples of the material include metals such as stainless steel, resins such as polyester, polyamide, polycarbonate, and polyacetal.

  In order to facilitate the demolding of the paraffin block, the paraffin storage section is usually composed of a tapered container whose side wall extends from the bottom toward the opening.

  On the periphery of the opening of the paraffin container, a placement unit for the paraffin block adhering body is provided. The mounting part is not particularly limited as long as the paraffin block adhering body can be placed on the periphery of the opening of the paraffin block housing part, but preferably is formed by a horizontal part extending outward from the periphery of the opening. Is done. More preferably, the horizontal portion and a wall portion extending in a substantially vertical direction outside the horizontal portion are formed, and more preferably, a substantially horizontal edge portion is further formed in the outer direction of the wall portion. It consists of a shape.

  The wall part is fixed so that the paraffin block adhering body does not slide freely, and the edge part supports the large paraffin block adhering body from the back side and stably fixes it. Improve.

At least two placing parts for the paraffin block adhering body are provided. As described above, the two or more mounting portions are located in the mounting portion A and are opposed to each other when the mounting portion provided at the periphery of the opening of the paraffin block housing portion is A. Any one or two of the two sides is provided with at least one placement part B at a position lower than the placement part A described above.
For example, when the paraffin container is made of a rectangular container, there are two opposing sides, a long side and a short side. For example, one placement is placed on two long sides. When the portion B1 is provided, the placement portion A and the placement portion B1 become two placement portions, which can cope with two types of paraffin block adhering bodies, and the placement portions B2 are also provided on the two short sides. And A, B1, and B2, a total of three mounting parts, which can handle three types of paraffin block adhering bodies, and two mounting parts B1 and B2 on the long side and two on the short side When the mounting portions B3 and B4 are provided, a total of five mounting portions A, B1, B2, B3, and B4 are provided, and five types of paraffin block adhering bodies can be handled.

  By making the shape of the paraffin storage part asymmetrical, the right and left of the slice sliced with the microtome are clearly distinguished, so that workability is improved and troubles such as misidentification of the specimen due to misidentification of the left and right are prevented. Therefore, the reliability of inspection is improved.
