Description

  The present invention relates to an embedding tray for preparing a histopathological specimen, and more specifically, when a paraffin block adhering body is produced using a cassette having a recording section provided on the side of a main body, paraffin adheres to the recording section. In particular, the present invention relates to an embedding tray for preparing a histopathological specimen that makes it difficult to see characters on the recording portion and does not require a complicated trimming operation to remove attached paraffin.

  Conventionally, as an embedding tray for preparing this type of histopathological specimen, the one shown in FIG. 23 has been frequently used. The embedding tray T includes a paraffin container T1, a cassette support T2 for horizontally mounting the cassette, and a cassette for stopping the movement of the cassette erected on the periphery. The locking portion T3 is a frame portion T4 provided horizontally on the periphery of the locking portion T3, and further includes a grip portion T5 provided laterally at a substantially central portion of the frame portion T4 in the longitudinal direction.

  Further, in recent years, it is composed of a paraffin storage portion formed of a rectangular container and a placement portion for a paraffin block adhering body provided at the periphery thereof, and at least two placement portions are provided, and two types having different sizes are provided. A tray for preparing a histopathological examination specimen that can handle the above cassettes is known (for example, see Patent Document 1).

  In order to prepare a microscope specimen using the above-mentioned histopathological specimen preparation tray, first, as shown in FIGS. 24 and 25, the sample S collected in the cassette body C1 is accommodated and a lid C2 is attached. The name and number of the subject are entered in the recording unit C3. Next, water is allowed to flow from the bottom of the cassette body C1 and the through-hole C4 formed in the lid C2, the specimen S is washed with water, the moisture in the specimen S is then removed with alcohol, and the liquid paraffin described later with xylene is removed. Confer affinity.

  Next, as shown in FIG. 26, the specimen S is transferred to the tray T, the bottom of the cassette body C1 is placed on the cassette support T2 of the tray T, and paraffin P is injected from above. In this case, the paraffin P is generally poured from the frame portion T4 of the tray T in terms of workability for pouring the paraffin P until it overflows. Next, after the paraffin P is cooled and solidified, the tray T is removed to obtain a paraffin block B in which the paraffin P in which the specimen S is embedded adheres to the bottom of the cassette body C1, as shown in FIG. . Thereafter, the specimen S embedded in paraffin with a microtome is sliced to obtain a thin piece, and a microscope specimen is obtained by subjecting this to a predetermined treatment such as staining.

  However, in the above method, as shown in FIG. 27, the name and number of the subject described in the recording section C3 of the cassette body C1 are covered with paraffin P1, and the recorded contents cannot be sufficiently confirmed. Trimming work for scraping off the paraffin P1 with a knife is essential. However, the solidified paraffin is hard, and the cutting operation of the paraffin P1 is extremely troublesome, and the workability is greatly reduced. In addition, the surface of the recording unit C3 is scratched during the scraping operation with the knife, and this scratch causes more and more paraffin to adhere, making the trimming operation more troublesome and also deteriorating the appearance of the cassette body C1. Moreover, it causes a decrease in the number of repeated uses.

On the other hand, in order to avoid the troublesome trimming operation of the paraffin P1, it is considered to inject the paraffin P so as to stop the level of the paraffin P below the cassette locking portion T3 so that the paraffin P does not cover the recording portion C3. However, in this case, careful attention is required for injecting the paraffin P1, and the infusion operation becomes troublesome and takes time, so that a significant decrease in workability is unavoidable.
On the other hand, if the paraffin P1 is not trimmed and the work is performed in a state in which the recording content of the recording unit C3 is not sufficiently confirmed, the test subject is mistakenly recognized, resulting in a serious loss of reliability. .

  In view of such circumstances, the present inventors have conducted intensive research to solve the above-described problems. As a result, the above phenomenon is caused by the fact that in the conventional tray, the cassette support portion T2 and the frame portion T4, which are composed of horizontal portions, are provided. Because it is wide, it is easy to retain paraffin, and it is easy to swell from here, and secondly, it is determined that the cassette locking portion T3 is unnecessarily high, and the horizontal portion that forms the cassette support portion of the tray is determined. It has been found that the initial purpose can be achieved by reducing the cassette locking portion as much as possible, and the present invention has been completed.

  The present invention has been made to achieve the above object, and claim 1 of the present invention is an embedding tray for preparing a histopathological specimen that is used by placing a cassette on the upper end of a paraffin container. The paraffin container comprises a rectangular container having an open top surface consisting of a bottom part and side walls provided around the bottom part, and the upper end of each side wall is placed on the paraffin container to lock the cassette. A wall is erected, a cassette support portion is formed at the boundary between the side wall and the locking wall, the cassette support portion is formed narrow or inclined so as not to retain paraffin therein, and the locking wall is substantially The embedding tray for preparing a histopathological examination specimen is characterized in that it is formed low so as not to cover the recording portion and does not have a substantially horizontal frame portion on the outer periphery of the locking wall.

  According to a second aspect of the present invention, there is provided an embedding tray for preparing a histopathological specimen according to the first aspect, wherein the width of the narrowly formed cassette support portion is 0.3 to 3 mm.

  According to a third aspect of the present invention, there is provided the embedding tray for preparing a histopathological specimen according to claim 1 or 2, wherein the minimum inclination angle of the cassette support portion formed in a slope shape is 45 ° or more. Content.

  A fourth aspect of the present invention includes an embedding tray for preparing a histopathological specimen according to any one of the first to third aspects, wherein the cassette support portion is formed intermittently.

  According to a fifth aspect of the present invention, there is provided an embedding tray for preparing a histopathological examination specimen according to the fourth aspect, wherein the cassette support portion is formed of a hemispherical protrusion.

  According to a sixth aspect of the present invention, there is provided an embedding tray for preparing a histopathological specimen according to any one of the first to fifth aspects, wherein a sub-supporting portion is provided at a corner of the paraffin accommodating portion. To do.

  According to a seventh aspect of the present invention, the height of the locking wall is not more than one-fourth of the height of the cassette placed on the paraffin container. The embedding tray for preparation of the described histopathological specimen is the contents.

  Claim 8 of the present invention is the pathological examination specimen according to any one of claims 1 to 7, wherein the gripping portion is provided laterally from the upper end of the locking wall where the recording portion of the cassette is not disposed. The contents are the embedding tray for creation.

  A ninth aspect of the present invention includes an embedding tray for preparing a histopathological specimen according to any one of the first to eighth aspects, wherein the shape of the paraffin container is asymmetrical.

  The embedding tray for preparing a pathological specimen according to the present invention is formed so that the cassette support portion is narrow or inclined so as not to retain paraffin therein, and the locking wall does not substantially cover the recording portion. In addition, since the frame wall is not provided with a substantially horizontal frame portion on the outer periphery of the locking wall, the paraffin is cut off downward by the open locking wall. Further, there is substantially no horizontal portion where the paraffin stays and rises below the recording portion, and as a result, the paraffin does not cover the recording portion. Therefore, a trimming operation for scraping off the attached paraffin is unnecessary, the workability is improved, and the recorded contents can be confirmed easily and reliably.

  When the width of the cassette support part is 0.3 to 3 mm, no paraffin stays in this part, preventing the solid paraffin from staying and rising, making it easy to check the recording part and placing the cassette securely. This is preferable. Further, even if the width exceeds 3 mm, the same effect can be obtained if the cassette support portion is an inclined surface having a minimum inclination angle of 45 ° or more.

  If the cassette support part is formed intermittently, the paraffin slides from between the cassette support parts, so that the retention of paraffin becomes more difficult to occur. As the shape of the cassette support portion, a hemispherical protrusion can be exemplified. In this case, paraffin can easily flow, and the installed cassette can be sufficiently supported.

  If the sub-supporting portion is provided at the corner of the paraffin accommodating portion, the cassette can be firmly supported even when the dimensional stability of the cassette or tray is poor, and a suitable paraffin block can be created. Although the paraffin stays and rises somewhat on the sub-bearing part, in the normal case, the subject number is not written in the corner part, so the raised paraffin does not prevent the recording from being read.

  The height of the locking wall is preferably equal to or less than a quarter of the height of the cassette, and when this is the case, the characters that are substantially described are not covered with paraffin.

  Also, if the gripping part is placed from the upper end of the locking wall of the wall part where the recording part of the cassette is not arranged, even if paraffin rises on the gripping part, the subject number etc. described in the recording part is covered. In addition, since the tray can be easily handled, workability is greatly improved.

  Furthermore, if the shape of the paraffin container is left-right asymmetric, the right and left sides of the specimen can be discriminated by the shape of the paraffin when a microscope specimen is prepared, reducing the risk of sample mix-up and improving the reliability of the inspection. To do.

  The embedding tray (hereinafter simply referred to as an embedding tray) for preparing a pathological specimen according to the present invention is used by placing a cassette on the upper end of the paraffin container. The embedding tray of the present invention comprises a rectangular container having an open top surface comprising a bottom part and a side wall standing around the paraffin container, and a cassette is placed on the paraffin container from the upper end of each side wall. A locking wall for standing and locking is erected, a cassette support part is formed at the boundary between the side wall and the locking wall, and the cassette support part is formed in a narrow or slanted shape so as not to retain paraffin therein. The wall is formed low so as not to substantially cover the recording portion, and a substantially horizontal frame portion is not provided on the outer periphery of the locking wall.

  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.

From the upper end of each side wall, a locking wall for standing and locking the cassette on the paraffin housing is provided. The height of the locking wall is made low so as not to substantially cover the recording portion in order to reduce the paraffin covering the side portion of the cassette and reliably read characters and the like written on the recording portion.
The specific height of the locking wall may be appropriately determined according to the size of the cassette, and is not particularly limited. However, in consideration of the size of characters described in the recording unit, the height of the cassette is preferably set. If it is 1/4 or less, more preferably 1/5 or less, there is little possibility that characters or the like written on the recording part will be hidden, the recording part is not substantially covered, and usually solid paraffin is used. Fills the through hole at the bottom of the cassette body and sufficiently engages, so that a suitable paraffin block can be obtained.

  The height of the locking wall may be the same over the entire circumference, but it is also possible to form a part of the locking wall to be low and to form a paraffin discharge section. If it does in this way, excess paraffin will be discharged | emitted from a paraffin discharge part, and the rise of the paraffin after solidification will be suppressed. Although the magnitude | size of a paraffin discharge | emission part is not specifically limited, It is preferable to provide a part about 0.5-1 mm lower than another part by the width | variety of about 1-2 mm in width.

  In the present invention, in order to place the cassette on the paraffin storage portion, a cassette support portion is formed at the boundary between the side wall and the locking wall. The cassette support portion is formed in a narrow or slanted shape, so that paraffin does not stay in the cassette support portion, so that there is no possibility that the paraffin is solidified and the characters in the recording portion are hidden. Specifically, the width of the cassette support portion is preferably about 0.3 to 3 mm, more preferably 0.5 to 2 mm, and still more preferably 0.5 to 0.8 mm. If it is less than 0.3 mm, the bottom of the cassette may be smaller than the cassette support due to dimensional errors in the manufacture of the cassette or embedding tray, and the cassette may not be fully supported and may fall into the paraffin housing. . Moreover, when it exceeds 3 mm, there exists a tendency for paraffin to stay on this cassette support part, and to solidify in the raised state.

  It is preferable that the cassette support portion is formed in a slope shape because paraffin tends to slide along the slope and does not stay. In particular, an advantageous effect can be obtained when the width of the cassette support portion is large. In this case, it is preferable that the minimum inclination angle of the cassette support portion is 45 ° or more. If it is less than 45 °, there is a risk that paraffin may stay depending on the width of the cassette support. The upper limit of the tilt angle is not particularly limited. If the tilt angle is smaller than 90 °, the cassette can be placed. However, if the tilt angle is too large, the paraffin container itself becomes too deep and difficult to handle. In practice, a degree smaller than the inclination angle of the side wall by about 10 to 40 ° is appropriate.

  In the embedding tray of the present invention, the cassette support portion may be provided continuously around the entire circumference, but may be provided intermittently. In this case, since the paraffin slides down from the gap of the cassette support portion, it becomes more difficult to stay and the swell of paraffin is suppressed. More preferably, the cassette support portion is a hemispherical protrusion. In this case, the paraffin slides down on the surface of the hemispherical protrusion, and the swell of paraffin is further suppressed.

You may provide a subbearing part in each upper-end corner | angular part of a paraffin accommodating part. The sub-supporting portion is not particularly limited as long as the cassette can be placed thereon, but a structure in which the corner portion of the paraffin accommodating portion is slightly inwardly inserted and the upper end of this portion is the cassette supporting portion can be exemplified.
Paraffin may swell on the sub-supporting part and cover the corner of the cassette, but the subject number for identifying the specimen is usually written near the center of the recording part. There is almost no fear of being hidden by paraffin rising at both ends. However, in order to further reduce this fear, it is preferable that at least the sub-supporting portion in contact with the side wall on which the recording portion is disposed be as small as possible.

  In order to make the embedding tray of the present invention easy to handle, a grip portion may be provided on the side wall or the locking wall. Considering the manufacturing process of the embedding tray, it is easy to provide the gripping portion at the upper end of the locking wall. However, since the paraffin rises on the gripping portion, the recording wall of the cassette is not arranged. It is preferable to lay from the top. In this way, even if the paraffin swells on the grip portion, there is no particular inconvenience because the characters in the recording portion are not hidden.

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 mistaking the specimen due to misidentification of the left and right are prevented. , Improve the reliability of inspection.
The method of making the left-right asymmetry is not particularly limited, but for example, a method of changing (enlarging) the radius of the corners or a method of corrugating the side wall where the recording unit is not arranged can be employed.

  The cassette for producing the paraffin block in the embedding tray of the present invention is not particularly limited as long as it has a recording portion on the side surface. As a typical cassette, a microtome adapter is provided on the side surface as shown in FIGS. And a cassette having an adapter locking portion C5 for locking to the tape, a cassette having a sloped recording portion as shown in FIGS. 22 and 25, and the like.

  Hereinafter, the present invention will be described in more detail with reference to the drawings. However, it is needless to say that the present invention is not limited to only the embodiments.

Example 1
As shown in FIGS. 1 to 3, the embedding tray 1 of the present embodiment includes a paraffin container 2 made of a rectangular container formed from a bottom 3 and a side wall 4 surrounding the bottom 3, and an upper end of the side wall 4. That is, it consists of a locking wall 6 erected at the opening of the paraffin storage part 2 and a gripping part 7 provided laterally from the upper end of the locking wall 6 on the long side.
As shown in the partially enlarged view of FIG. 4, a cassette support portion 5 is formed at the boundary between the side wall 4 and the locking wall 6. Since the cassette support portion 5 in the present embodiment is a horizontal portion having a narrow width that is laterally provided from the upper end of the side wall 4, the paraffin hardly stays on the cassette support portion 5.

  FIG. 4 is a diagram showing a cross-sectional view of the embedding tray 1 of the present embodiment by a solid line and a sample S and a cassette C by a broken line. The cassette C in FIG. 4 is the same as that shown in FIGS. The embedding tray 1 is used by putting the specimen S into the paraffin container 2 and placing the cassette body C1 on the cassette support 5 as shown by the broken line. In this case, the recording unit C3 of the cassette body C1 is arranged on either side where the gripping unit 7 is not provided, specifically, the left and right sides in FIG. 4 (the right side and the left side in FIG. 1). Is arranged on the right side.

In the left and right sides of the embedding tray 1 of this embodiment, the locking wall 6 does not have a horizontal frame portion, so to speak, it is left uncut, and paraffin is fed from the side wall 4 to the locking wall 6 at the upper end. There is no wide horizontal part to stay. Therefore, as shown in FIG. 5, in the paraffin block B used using the embedding tray 1 of the present embodiment, the paraffin is cut down by the upper end of the unfastened locking wall 6 and also in the horizontal portion. The solidified paraffin does not rise and the subject number N etc. described in the recording part is not hidden.
In FIG. 5, the extra paraffin P1 is raised on the gripping portion 6. However, the gripping portion 6 is provided laterally from the upper end of the locking wall 6 where the recording portion of the cassette is not disposed. P1 does not hide the character N or the like in the recording part.

  In this embodiment, the size of the paraffin container is 40 mm × 28 mm at the opening, 36.6 mm × 25.6 mm at the bottom, and 8 mm in height. The height of the locking wall erected at the upper end of the paraffin storage part is 1.2 mm, the gripping part 7 installed horizontally from the upper end is 2 mm × 20 mm, and the width of the cassette support part is 0.2 mm. is there. Since the cassette to be used has a height of 6.4 mm, the height of the locking wall is not more than a quarter of the cassette height (1.2 / 6.4).

Example 2
As shown in FIGS. 6 to 8, the embedding tray 1 of the present embodiment includes a paraffin container 2 made of a rectangular container formed of a bottom 3 and a side wall 4 surrounding the bottom 3, and an upper end of the side wall 4. That is, it includes a locking wall 6 erected at the opening of the paraffin storage portion 2 and a gripping portion 7 provided laterally from the upper end of the locking wall 6. Paraffin discharge sections 6 a are provided on both sides of the grip section 7.
As shown in the partially enlarged view of FIG. 9, a cassette support portion 5 is formed at the boundary between the side wall 4 and the locking wall 6. Since the cassette support part 5 in this embodiment is formed in an inclined shape from the upper end of the side wall 4, the paraffin is less likely to stay on the cassette support part 5.

  FIG. 9 is a diagram showing a cross-sectional view of the embedding tray 1 of the present embodiment by a solid line and a sample S and a cassette C by a broken line. The cassette C in FIG. 4 is the same as that shown in FIGS. The embedding tray 1 is used by putting the specimen S into the paraffin container 2 and placing the cassette body C1 on the cassette support 5 as shown by the broken line. In this case, the recording unit C3 of the cassette body C1 is disposed on either side where the gripping unit 7 is not provided, specifically, the left and right sides in FIG. 9 (the right side and the left side in FIG. 5). Is arranged on the right side.

In the left and right sides of the embedding tray 1 of this embodiment, the locking wall 6 does not have a horizontal frame portion, so to speak, it is left uncut, and paraffin is fed from the side wall 4 to the locking wall 6 at the upper end. There is no horizontal part to stay. Therefore, as shown in FIG. 10, in the paraffin block B used by using the embedding tray 1 of the present embodiment, the paraffin is cut down by the upper end of the cut-off locking wall 6 and also in the horizontal portion. The solidified paraffin does not rise and the subject number N etc. described in the recording part is not hidden.
In FIG. 10, the extra paraffin P1 is raised on the gripping portion 6. However, the gripping portion 6 is provided laterally from the upper end of the locking wall 6 where the recording portion of the cassette is not disposed. Does not conceal the character N or the like in the recording part.

  In this embodiment, the size of the paraffin container is 40 mm × 28 mm at the opening, 36.6 mm × 25.6 mm at the bottom, and 8 mm in height. The height of the locking wall erected at the upper end of the paraffin storage part is 1.2 mm, the gripping part 7 installed horizontally from the upper end is 2 mm × 20 mm, the paraffin discharge part 6 a is 1.5 mm wide, and the height is high. 0.5 mm. The cassette support has a width of 0.3 mm and a minimum inclination angle of 45 °. Since the cassette to be used has a height of 6.4 mm, the height of the locking wall is not more than a quarter of the cassette height (1.2 / 6.4).

Example 3
As shown in FIGS. 11 to 13, the embedding tray 1 of the present embodiment includes a paraffin container 2 made of a rectangular container formed of a bottom 3 and a side wall 4 surrounding the bottom 3, and an upper end of the side wall 4, That is, it includes a locking wall 6 erected at the opening of the paraffin storage portion 2 and a gripping portion 7 provided laterally from the upper end of the locking wall 6.
As shown in the partially enlarged view of FIG. 14, a cassette support portion 5 is formed at the boundary between the side wall 4 and the locking wall 6. The cassette support portion 5 in the present embodiment is formed by pushing the boundary between the side wall 4 and the locking wall 6 from the outside by pressing and projecting inward. Further, since the cassette support portion 5 is formed intermittently, the paraffin slides down from the gap of the cassette support portion 5 and is more unlikely to stay.

  The right and left upper corners of the paraffin container 2 are slightly inwardly bent and rounded, and a sub-supporting portion 5a extends horizontally from the upper end. The lower left corner is larger than the other corners, and the sub-bearing portion 5a extending from the upper end is also enlarged. As a result, the paraffin container 2 is asymmetrical, and even after a microscope specimen is prepared from the paraffin block B, the orientation of the specimen can be determined by looking at the shape of the paraffin containing the specimen.

  FIG. 14 is a diagram showing a cross-sectional view of the embedding tray 1 of the present embodiment by a solid line and a sample S and a cassette C by a broken line. The cassette C in FIG. 14 is the same as that shown in FIGS. The embedding tray 1 is used by loading the specimen S into the paraffin storage part 2 and placing the cassette body C1 on the cassette support part 5 and the sub-support part 5a as shown by the broken line. In this case, the recording unit C3 of the cassette body C1 is arranged on either side where the gripping unit 7 is not provided, specifically, the left and right sides in FIG. 14 (the right side and the left side in FIG. 11). Is arranged on the right side.

In the left and right sides of the embedding tray 1 of the present embodiment, the locking wall 6 has no horizontal frame portion, so to speak, it is left open, and from the side wall 4 to the locking wall 6 at its upper end, Except for the support portion 5a, there is no horizontal portion where the paraffin stays. Therefore, as shown in FIG. 15, in the paraffin block B used with the embedding tray 1 of the present embodiment, the paraffin is cut down by the upper end of the cut-off locking wall 6 and at the horizontal portion. The solidified paraffin does not rise and the subject number N etc. described in the recording part is not hidden.
In FIG. 15, the paraffin P slightly rises at the upper part of the sub-supporting portion 5 a at the corner of the paraffin block B, but this level of rise is not particularly a problem. Since the recording is performed closer to the center of the recording unit C3, there is substantially no trouble in reading the recording. Although extra paraffin P1 is raised on the gripping portion 6, the gripping portion 6 is provided laterally from the upper end of the locking wall 6 where the recording portion of the cassette is not disposed. Of course, this paraffin P1 is the recording portion. N is not hidden.

  In this embodiment, the size of the paraffin container is 40 mm × 28 mm at the opening, 36.6 mm × 25.6 mm at the bottom, and 8 mm in height. The height of the locking wall erected at the upper end of the paraffin storage portion is 1.2 mm, and the gripping portion 7 provided laterally from the upper end is 2 mm × 20 mm. The cassette support portion has a width (projection height) of 0.5 mm and a minimum inclination angle of 45 °. Since the cassette to be used has a height of 6.4 mm, the height of the locking wall is not more than a quarter of the cassette height (1.2 / 6.4).

Example 4
16 to 18, the embedding tray 1 of this embodiment includes a paraffin container 2 made of a rectangular container formed of a bottom 3 and a side wall 4 surrounding the bottom 3, and an upper end of the side wall 4, that is, an upper end of the side wall 4. The locking wall 6 is erected on the opening of the paraffin container 2.
As shown in the partially enlarged view of FIG. 19, a cassette support portion 5 is formed at the boundary between the side wall 4 and the locking wall 6. The cassette support portion 5 in this embodiment is formed by a hemispherical protrusion protruding near the center of the boundary between the side wall 4 and the locking wall 6. Accordingly, the paraffin easily slides down from the surface of the cassette support portion 5 and is more difficult to stay.

The right corner of the paraffin container 2 is slightly inwardly bent and rounded, and the left corner is larger than the right corner. As a result, the paraffin container 2 is asymmetrical, and the orientation of the specimen can be determined by looking at the shape of the paraffin containing the specimen even after the microscope specimen is prepared from the paraffin block.
Sub-bearing portions 5a are respectively extended from the upper ends of the corner portions that have been rounded.

  FIG. 19 is a diagram showing a cross-sectional view of the embedding tray 1 of the present embodiment by a solid line and a sample S and a cassette C by a broken line. The cassette C in FIG. 19 is the same as that shown in FIGS. The embedding tray 1 is used by loading the specimen S into the paraffin storage part 2 and placing the cassette body C1 on the cassette support part 5 and the sub-support part 5a as shown by the broken line. In the case of the present embodiment, since the grip portion 7 is not provided on any side of the embedding tray 1, the recording unit C3 can be arranged on any side, in other words, the subject number or the like on any side of the cassette C. Even if N is described, there is no fear of being hidden by the raised paraffin P.

In each of the upper, lower, left and right side walls 4, 4 of the embedding tray 1 of this embodiment, there is no horizontal portion where paraffin stays except for the sub-supporting portion 5a. Therefore, as shown in FIG. 20, in the paraffin block B used by using the embedding tray 1 of this embodiment, the solidified paraffin does not rise and the subject number N described in the recording unit is not hidden. .
As shown in FIG. 20, the paraffin P slightly rises at the upper part of the sub-supporting portion 5a at the corner of the paraffin block B, but this level of rise is not particularly a problem. Since the number N is recorded near the center of the recording unit C3, there is substantially no trouble in reading the record.

  In this embodiment, the size of the paraffin container is 40 mm × 28 mm at the opening, 36.6 mm × 25.6 mm at the bottom, and 8 mm in height. The height of the locking wall erected at the upper end of the paraffin storage portion is 0.8 mm, and the width (projection height) of the cassette support portion is 0.5 mm. Since the height of the cassette to be used is 6.4 mm, the height of the locking wall of the side wall on which the recording unit is arranged is equal to or less than a quarter of the height of the cassette (0.8 / 6. 4).

  As described above, the embedding tray for preparing a histopathological specimen according to the present invention has a paraffin adhering to the recording portion when the paraffin block adhering body is prepared using the cassette having the recording portion provided on the side surface of the main body. Thus, the characters on the recording section are not easily seen, and the complicated trimming work for removing the attached paraffin is unnecessary, so that the workability for preparing the histopathological specimen and the reliability of the examination are greatly increased. Increased and its usefulness is tremendous.
