Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clinician transferring a biopsy sample collected from a human body to a pathological examination room or the like, for example, in an endoscopy, in order to determine a method of diagnosing and treating a disease. When the clinician performs a fixed transfer of a biopsy sample from a biopsy collection instrument such as forceps or the like to prevent the biopsy sample from being deteriorated, a perforated dish (including a cassette) in a fixed transfer container
The present invention relates to a biopsy sample storage device necessary for securely storing a sample while minimizing crushing of the sample, and a storage method therefor.

[0002]

2. Description of the Related Art Conventionally, when performing this type of work, when a clinician stores a sample in a fixed transfer container from a biopsy collection instrument such as forceps of an endoscope, the sample is preferably prevented from being crushed. For this purpose, pinch and collect the sample with paper tweezers formed by bending the short diagonal of the diamond-shaped paper, or use a triangular paper cut into a triangular shape or a biopsy sample with a sharp-pointed instrument such as a needle or toothpick. Is collected from the forceps, and the sample is directly stored in a fixed transfer container, or placed in a divided cassette or a divided perforated dish, and stored again in the fixed transfer container and transferred. Is being done.

[0003] Alternatively, the sample is directly immersed together with the forceps from which the sample was directly taken in a fixative or saline solution in a fixed transfer container,
A method of washing a biopsy sample into a fixed transfer container, or directly collecting a biopsy sample from forceps or the like with a pinching instrument such as tweezers and storing the sample in the fixed transfer container, or a cassette or a multi-ported sample There is a method of putting the plate in a dish and storing it again in a fixed transfer container.

[0004] Although the biopsy samples are less crushed by the above-mentioned conventional method, accommodating them is necessary to store each biopsy sample in a compartment of a divided cassette or a divided perforated dish, and directly When storing each biopsy sample in a fixed transfer container, the position number of the biopsy sample is likely to be unclear,
To clarify the position number, each biopsy sample needs its own fixed transfer container, which increases the cost.

In the above-mentioned conventional method of washing a biopsy sample from a forceps in a fixed transfer container, the sample is minimized in crushing, but there is no backing paper for the biopsy sample. Biopsy samples are difficult to identify,
In order to reliably discriminate the position numbers of the samples, a fixed transfer container for each position number of the biopsy sample is also required, which increases the cost. In addition, when the sample is washed off in a physiological saline solution, it takes time to replace the physiological saline solution with a fixative.

[0006] Furthermore, although the collection of a biopsy sample with a clamping instrument such as tweezers is an easy method of collection, the crushing of the sample is the worst, and the conventional sample collection and the fixed transfer method involve a plurality of methods. The possibility of mistakes or misidentifications when writing or confirming the patient label on the container, and ambiguity or misidentification of the position number increases.

[0007] Further, an invention relating to a specimen transfer in a perforated dish, a biopsy sample inclusion cassette or a fixed transfer container for a biopsy sample, and a subsequent pathological specimen preparation step, which was filed earlier by the present inventor (Japanese Patent No. 3049537). No.) is very smooth,
No sample is lost or mixed. However, when a clinician collects a biopsy sample from a patient to request a pathological diagnosis test and stores it in a fixed transfer container, especially when storing the biopsy sample in a small compartment of a perforated dish, triangular paper Storing a biopsy sample in a perforated dish or compartmentalized compartment of a compartmentalized cassette or in a predetermined position using a toothpick, a needle, paper tweezers, or the like requires a skillful experience and requires a triangular paper or a toothpick. Even when a biopsy sample is taken from the forceps by using a forceps or a needle or paper tweezers, the sample is crushed.

[0008]

SUMMARY OF THE INVENTION The present invention eliminates the problems of the prior art described above, for example, when storing in a divided cassette or the like, the biopsy sample is not crushed and the operation of the sample is not required. Or the need to prepare a separate fixed transfer container for each biopsy sample, and to replace the saline solution for washing the biopsy sample from forceps etc. with the fixative solution for transfer. Making it unnecessary,
The cost is reduced during that time.

[0009]

According to the present invention, there is provided a device for storing a biopsy sample, wherein a biopsy sample is fixed between a lower end edge of a funnel for storing a fixed solution of the biopsy sample for a predetermined time and an upper end edge of a fixing solution receiving tank. The upper and lower surfaces of the flange portion of the test sample perforated dish or the bottom outer wall of the biopsy sample cassette are tightly sandwiched, and the space surrounded by the inner surface of the fixation solution receiving tank and the lower surface of the perforated dish is decompressed. A device that communicates with the source.

Further, according to the method for storing a biopsy sample of the present invention, the lower end of a funnel is placed on a receiving tank via a biopsy sample perforated dish or a biopsy sample cassette, and the biopsy sample is placed in the funnel. The fixative is stored for a predetermined time, and the biopsy sample in the state of being collected at the tip of the forceps is immersed in the fixative together with the tip of the forceps, washed off from the tip of the forceps, and settled in the fixative. It is a method of storing in the perforated dish or the cassette.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The storage device for a biopsy sample according to the present invention is a funnel 3 for storing a fixing solution of a biopsy sample 1 or a gelling agent for fixing, the inside of which is a vertical partition plate. 1
A biopsy in which the same number of the chambers 21 to 24 as the number of the injection chambers 31 to 34 are formed by the ridges 13 below the lower edge 4 of the funnel 3 divided into a plurality of the injection chambers 31 to 34 by 2. The sample is placed on the upper edge 6 of the receiving tank 5 for the fixative 2 of the biopsy sample 1 via the flange 8 of the sample porous dish 7, and a decompression housing 14 is provided outside the receiving tank 5. A communication hole 11 and a communication groove 11 a are formed between the space 9 surrounded by the lower surface 7 a of the plate 7 and the inside of the pressure reducing source 10.

More specifically, the funnel 3 is formed of an inverted cone-shaped upper half 3a and a cylindrical lower half 3b, and the cylindrical lower half 3b is a receiving opening of the lid 15 of the receiving tank 5. 16, a space 9 surrounded by the inner surface of the receiving tank 5 for the fixative 2 and the lower surface 7 a of the perforated dish 7, and a communication hole 11 and a communication groove 11 a formed between the decompression sources 10. The pressure reducing housing 14 provided outside the receiving tank 5 and the lower surface of the flange 8 of the perforated dish 7 and the receiving tank 5.
Is formed between the upper edges 6.

In the embodiment of the method for storing a biopsy sample according to the present invention, as shown in FIGS. 1 to 4, a lower end edge 4 of a funnel 3 is placed on a receiving tank 5 via a perforated dish 7. The fixative 2 of the biopsy sample 1 is stored in the funnel 3, and the forceps 1
The biopsy sample 1 collected at the tip 18 of the sample 7 is immersed together with the tip 18 of the forceps 17 as it is, washed off from the tip 18 of the forceps 17, and only the biopsy sample 1 is settled in the perforated dish 7. Is the way.

When only the biopsy sample 1 is settled in the perforated dish 7, the decompression source 10 such as the cylinder is fitted and communicated with the suction port 20 of the decompression housing 14, and the decompression chamber 14 a in the decompression housing 14 is provided.
Is reduced, and the decompression chamber 14a and the communication hole 11
The pressure of the space 9 in the receiving tank 5 communicating with the communication groove 11a is reduced.

Due to the decrease in the pressure in the receiving tank 5, the perforated dish 7
The fixing liquid 2 stored on the upper surface of the fixing liquid 2 due to the surface tension of the fixing liquid 2 itself is sucked into the receiving tank 5 from the lower surface 7a of the perforated dish 7 and has a size larger than the hole 7d submerged in the perforated dish 7. Only the fixative 2 leaving the biopsy sample 1 is sucked into the receiving tank 5 and dropped in the form of a droplet 2a.

The present invention is not limited to injecting or filling air into the decompression casing 14 as shown in FIGS. 1 to 5, and adjusting the internal pressure of the decompression casing 14 to the outside pressure. ,
As shown in FIG. 27, the same operation can be performed by injecting or filling the same liquid as the fixing liquid 2 or the like, instead of the gas such as air, into the decompression housing 14.

At this time, as shown in FIG. 27, the fixing solution 2 and the fixing gelling agent are suctioned in advance into a syringe 27 or the like which is both a pressure reducing source and an injector, and as shown in FIG. The fixative 2 or the fixative gelling agent is injected and filled in the direction of the arrow A in the reverse direction from the suction port 20 of the decompression housing 14 of the storage device for the biopsy sample 1 to fill the fixative 2 with the fixative 2. Alternatively, the fixed gelling agent is kept at the intended water level H, and after collecting and storing the biopsy sample 1 in the funnel 3, the fixing solution in the storage device for the biopsy sample 1 is again placed in the syringe 27. 2 or the fixed gelling agent is sucked and collected in the direction of arrow B, whereby the biopsy sample 1 is stored in a target storage plate 7 or a predetermined storage location at the bottom of the cassette, and
In the syringe 27, a fixed transfer container for a biopsy sample which has already been filed by the present inventors (Japanese Patent Application No. 2000-36819).
The fixing solution 2 or the fixing gelling agent to be injected into the inside can also be collected.

At this time, the plurality of injection chambers 31 to 34 inside the funnel 3 and the storage chambers 21 to 24 of the perforated dish 7 divided by the ridges 13 in the same number are made to face each other. As a result, the biopsy sample 1 washed off from the distal end 18 of the forceps 17 into the relatively large injection chambers 31 to 34 of the inverted cone-shaped upper half 3a of the funnel 3 as described above.
Automatically falls gradually in the fixative 2 without touching any other objects, and each of the small storage chambers 21 to 21 of the perforated dish 7 respectively.
24 accurately accommodated.

Thereafter, the funnel 3 and the lid 15 are removed from the decompression chamber 14a and the receiving tank 5, respectively. Subsequently, the perforated dish 7 containing the biopsy sample 1 is removed from the receiving tank 5, and the lid 7b of the perforated dish 7 is removed. The lid 7b is folded by the hinge 7c and the lid 7b is closed. Then, the lid 7b is put in a transfer container or the like and moved to an examination room or the like, where the biopsy sample 1 is inspected.

In a hospital having a pathological examination room in a hospital, a biopsy sample contained in a perforated dish in a storage container for a biopsy sample as shown in FIGS. The messenger may be transferred to the pathological examination room as it is.

As shown in FIG. 3, before the transfer, the vacuum source 10 such as a syringe is used to suction under reduced pressure or the stopper 35 of the suction port 20 is pulled out as shown in FIG. An excess amount of the fixing solution 2b larger than the amount of the fixing solution necessary for fixing the biopsy sample 1 in the perforated dish 7 in the space 9 in the perforated dish 7 without drying is transferred from the communication hole 11 of the receiving tank 5 to the decompression chamber 14a. After overflowing, the biopsy sample 1 is contained in the storage chamber in the perforated dish 7.

Further, as shown in FIG. 1, the syringe 10 is not operated while the syringe 10 is fitted in the suction port 20.
That is, in the case where the suction port 20 is closed and no vacuum suction or natural fall is performed, and in the case where the suction port 20 is closed with the stopper 35 or the syringe 10 as shown in FIGS.
28, since the inside of the receiving tank 5 is not communicated with the outside air as shown in FIG. 28, the fixing liquid 2 in the funnel 3 does not fall naturally into the receiving tank 5 but stays in the funnel 3 while being picked up by the forceps 11. The biopsy sample 1 is sufficiently washed off the forceps 11.

The syringe 10 or the stopper 3 is inserted through the suction port 20.
When the suction port 20 is opened after removing 5, since the inside of the receiving tank 5 communicates with the outside air, the fixing liquid 2 in the funnel 3 gradually starts to fall naturally into the receiving tank 5. At this time, the natural falling speed is much slower than that when suction is performed by the reduced pressure source 10 such as the syringe, but there are cases where there is no problem in practical use.

The present invention is not limited to the embodiment shown in FIG. 1 to FIG.
Other embodiments shown in FIG. 2 are also included. FIGS. 10 to 18 show that the partition plate 12 of the funnel 3 shown in FIGS.
This is an example in which the partition plate has only one partition point at the center corresponding to the divided storage chambers 21 to 24 of the perforated dish 7, but there is no partition point where the partition plate 12 intersects. The upper half 3a and the lower half 3b are configured to be detachable, and the partition plate 12 of the upper half 3a is also configured to be detachable. With this structure, a storage funnel having a plurality of partition points can be formed of synthetic resin.

In the embodiment shown in FIGS. 10 to 18,
The perforated dish 7 (including the cassette) does not necessarily require a plurality of storage rooms. In such a case, the inventor has already applied for the invention of a biopsy sample by using a fixing support (Japanese Patent Application No. 11-76843).
When (1) is used in combination with the fixing gelling agent as the fixing solution 2 of the present invention, the biopsy sample 1 can be fixed and held reliably, and it is very convenient.

FIGS. 19 and 20 show the upper half 3a of the funnel 3 and the lower half of the cylindrical shape so that the pressure reducing housing 14 and the lid 15 of FIGS. 1 to 9 and FIGS. 10 to 18 can be shared. 19 and FIG. 20, the right side view of FIGS. 19 and 20 shows the outer surface of the lower surface 7a of the perforated dish 7 having no ridge 13. This is an embodiment in which a biopsy sample is stored on the side surface.
Is closed from the beginning, and is placed on a predetermined upper edge B (6b) of a receiving tank B (5b) adjacent to the receiving tank 5 with the lower surface 7a of the perforated dish 7 facing upward, and the lid 15 is moved right and left. The lower surface 7a of the perforated dish 7 and the lid 7b
And the lower edge 4 of the funnel 3 and the lower end of the receiving port 16 and the receiving tank B
(5b) and the upper end edge B (6b) of the perforated dish 7
When the biopsy sample is stored and installed on the outer surface of the lower surface 7a of the above, and the biopsy sample is stored and installed on the inner and outer surfaces of the lower surface 7a of the perforated dish 7 having no such ridge 13, It is very convenient to use the fixing support agent for the biopsy sample and the fixing gelling agent as the fixing solution 2 which have already been applied for invention.

FIG. 21 shows a cylindrical lower half 3b of the storage funnel.
This is an embodiment in which a part of the functional passage is integrally formed in the socket of the lid 15 when the lid is manufactured.

Further, FIGS. 22 and 23 show that the opening of the upper half of the funnel 3, the lower half 3b of the cylindrical shape and the decompression housing are formed by changing the shape according to the shape of the perforated dish 7 (including the cassette). This is an example of another embodiment in which the funnel opening, the decompression housing 14 and the lid 15 are not square but cylindrical.

In the embodiment shown in FIGS. 1 to 23, the flange 7b of the biopsy sample porous dish 7 is tightly held between the lower edge 4 of the funnel 3 and the upper edge 6 of the receiving tank 5 for fixing fluid. However, the present invention is not limited to this, and instead of the biopsy sample perforated dish 7, a bottom outer wall 41 of a biopsy sample cassette 40 is sandwiched as shown in FIGS. 26, the upper edge 6 of the receiving tank 5 and the receiving port 16 of the lid 4
3, and a downwardly protruding ridge 4a is formed on the lower edge 4 of the funnel 3 as shown in FIG. It is also possible to carry out.

Therefore, as shown in FIG. 21, the decompression casing 14 can be formed thin as long as there is a space for accommodating the perforated dish 7 and the bottom of the cassette and a closed space passage connecting the funnel opening and the suction port. it can.

Therefore, as shown in the plan view of the decompression housing 14 in FIG. 32, the shapes of the receiving tank 5 and the communication hole 11 inside the decompression housing 14 can also be changed.

Further, as described above, since it is better for the sample to aspirate the biopsy sample 1 together with the fixative 2 by the vacuum source 10, the vacuum housing 14 is not subjected to the vacuum reduction or the vacuum reduction through the suction port 20. The sample was stored in a predetermined place of the perforated dish 7 (including the cassette) by releasing the internal pressure of the decompression housing 14 by removing the stopper of the suction port, and the air pressure between the upper and lower sides of the perforated dish 7 is relative. Although not shown, the biopsy sample storage device of the present invention can also be implemented by a method in which pressure is applied from the lid 19 side of the funnel opening to release compressed air from the suction hole.

[0033]

As described above, the present invention allows a clinician to accurately and easily store a biopsy sample collected from a human body with the tip of a forceps or the like in a small storage chamber of a divided perforated dish. In addition, there is no need to change the biopsy sample to another forceps or the like until the biopsy sample picked by the forceps is accommodated in the perforated dish, so that the biopsy sample is not crushed.

In particular, when the biopsy sample is separated from the forceps, it can be performed on a relatively large portion of the upper half of the funnel.
The operation is easily performed and can be performed in the fixative stored in the funnel, so that the biopsy sample is easily detached from the tip of the forceps, which also damages the biopsy sample. The risk is further reduced.

Furthermore, since the pressure or liquid pressure on the lower surface of the perforated dish can be reduced from the external pressure, the fixing solution in the perforated dish is efficiently sucked into a receiving tank located thereunder, and only the biopsy sample is removed. Can be stored in the perforated dish.

Therefore, the specimen preparation operation can be performed without opening and closing the lid of the perforated dish until the biopsy sample is packed together with the perforated dish together with the perforated dish, thereby preventing the sample from being lost, mixed or mixed. be able to.
