Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing case for dental instruments. In particular, the present invention relates to a storage case that can perform a length adjustment setting at the time of use, a disinfection / storage after use, and a small instrument used for root canal treatment such as a reamer and a file.

[0002]

2. Description of the Related Art Reamers and files (hereinafter, simply referred to as "reamers") are instruments used by dentists for root canal dilation and are similar to a town needle, and there are several types depending on the blade shape, thickness and length. A stopper ring, which is used by the dentist as a guide for the length of the root canal in the affected tooth of the patient, is slidably set on the needle portion. To adjust and set the position of the stopper ring, a graduated instrument called an end gauge is often used.

Patients' saliva and blood adhere to the reamer and must be frequently disinfected to prevent the transmission of disease. For this purpose, the used reamer is washed with water, and then subjected to disinfection and sterilization treatment in the order of chemical solution disinfection, ultrasonic cleaning, and autoclave (high pressure steam sterilization). Since a dentist uses a large amount of reamers every day, disinfection and sterilization work requires a lot of labor and time.

The reamer thus disinfected is stored in a storage case for the next use. This storage case is often a small case having a shelf with multiple holes. Insert the reamer into these holes for vertical storage and storage.

[0005]

As described above, the reamer requires the work of adjusting the length during use and disinfecting and storing after use. Conventionally, in each process, different equipment was used, so the process of taking out the reamer and returning it to the original was repeated.
In addition, the instruments used in each process, especially the end gauge, are precise and expensive.

[0006] It is an object of the present invention to provide a storage case in which the length adjustment setting of the reamer during use and the disinfection / storage after use can be performed in a single case.

[0007]

A storage case according to the present invention which achieves the above object is a storage case comprising a side plate and a shelf plate supported by this shelf plate and having a hole for inserting a reamer. The middle plate with which the tip of the plate comes in contact and a means for moving the middle plate up and down are provided. It is characterized by being formed from such a material.

Besides, although not essential to the present invention,
It is preferable to attach a bottom plate and a lid that can be opened and closed. The bottom plate is for increasing strength, and the lid is for removing dust during storage.

The whole is made of a material that can withstand disinfection such as chemicals, ultrasonic waves, autoclaves and the like, for example, a stainless steel plate. It is preferably porous or net except for the intermediate plate and the lid. The middle plate is a plate without holes because it is necessary for the tip of the reamer to contact, and the lid is also a plate without holes because it has the meaning of removing dust. If the side plate and the shelf plate are porous or net-shaped, it is not necessary to make another hole for fixing the reamer on the shelf plate, it becomes easier to dip the chemical solution through the mesh, and the tip of the reamer becomes the middle plate. It is advantageous in that it can be confirmed not only by touch but also by the naked eye through the mesh.

As a means for moving the middle plate up and down, for example, an elastic wire whose width can be easily expanded and reduced by a handle protruding from the side plate can be used. In addition, a mechanism for precisely moving the middle plate up and down by using gears or screws can be adopted.

[0011]

According to the present invention, since the middle plate with which the tip of the reamer is in contact can be moved up and down and the side plates are provided with the scales for indicating the height of the middle plate, it is easy to adjust the length of the reamer. is there. Further, since the whole is made of a material that can withstand disinfection such as a chemical solution, ultrasonic waves, an autoclave, etc., it can be sterilized as it is.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a storage case according to an embodiment of the present invention.

The whole is a cube having a height and width of about 5 cm. Of course, the overall shape is not only a cube, but also a cuboid,
It may be cylindrical, and the size may be smaller or larger as necessary.

About 1 cm from the top of the side plate 2 forming the side surface
The shelf 4 is horizontally fixed to the lower position. However, the shelf plate 4 may be horizontally fixed at the position of the top of the side plate 2. The side plate 2 and the shelf plate 4 are formed from a porous or net-shaped stainless plate. For convenience of drawing, only a part of the drawing is drawn as a porous shape. FIG. 1 shows a state in which three reamers are inserted in the mesh of the shelf plate 4. Although not shown, a bottom plate may be horizontally provided at the lowermost portion of the side plate 2, and an openable / closable lid may be provided at the uppermost portion. The bottom plate is for increasing the strength of the container, and the lid is for removing dust during storage. Therefore, the lid needs to have a plate-like shape without holes.

A slot 8 is formed in one of the side plates 2 in the vertical direction. From this slot 8 to the wire handle 10a
Is protruding. This wire 10a is, for example, as shown in FIG.
As shown in FIG. 5, it is a part of the height adjuster 10 having a structure in which the left and right feet 10b of the tweezers are curved in a U shape.
Although not essential to the present invention, the non-slip 10 made of heat-resistant and chemical-resistant synthetic resin is provided at the tip of the foot of the height adjuster 10.
It is preferred to cover c. Figure 2 for wide containers
As shown in (b), a wire in which the foot 10b is curved in an S shape may be used. Further, in order to keep the height adjuster horizontal, as shown in FIG. 2 (c), after the foot 10b is bent to the left and right, the distal end 10d thereof may be extended vertically. In this case, it is necessary to previously form a U-shaped or U-shaped groove 12 (see FIG. 3) for accommodating and sliding the vertical end portion 10d in the side plate 2. When the grip 10a is picked up and a force is applied, the width of the wire is reduced and the slip stopper 10c is separated from the side plate 2, so that the position of the height adjuster 10 can be changed. When the hand is released from the handle 10a, the wire is restored to the original width by the elastic force of the wire, and the slip stopper 10c hits the side plate 2 and presses it, so that it is fixed at that position.

As shown in the sectional view of FIG. 4, the middle plate 14 is placed on the height adjuster 10. The middle plate 14 is a plate having almost the same size as the length and width of the container and having no holes. Since the middle plate 14 is simply placed on the height adjuster 10, the upper and lower positions can be changed as the position of the height adjuster 10 is changed.

In order that the distance from the shelf plate 4 to the middle plate 14 can be seen, the side plate 2 is engraved with a scale 16 whose number increases downward with the position of the shelf plate as 0.

The usage of the container of the present invention is as follows.
First, in order to adjust the length of the reamer 6, the middle plate 14 is set to a desired height while looking at the scale 16 of the side plate 2. For that purpose, the elastic wire handle 10a is operated in the above-described manner.
By changing the position by grasping or releasing by hand. Next, insert the foot 6b of the reamer into the hole of the shelf and insert the foot 6b.
The stopper ring 6c is fixed at the position where the tip of the contact.

For disinfection and sterilization of the reamer after use,
After only washing with water, it is inserted into the mesh of the shelf board 2, and a series of disinfection and sterilization steps of the container in that state, that is, chemical solution disinfection, ultrasonic cleaning, and autoclave (high pressure steam sterilization) are performed. After disinfection, close the lid and use it as a storage container.

[0020]

According to the present invention, the length adjustment setting of the reamer at the time of use and the disinfection / storage after use can be carried out in a single case, which is convenient. further,
The material used is a porous or net-shaped stainless plate or elastic wire and can be manufactured at low cost.
