Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disinfecting device for root canal treatment needles such as reamers and files used in dentistry.

[Conventional technology]

As is well known, a root canal treatment needle is a pin-shaped needle having a grip handle at its base.

Methods for cleaning and sterilizing used root canal treatment needles include boiling them, immersing them in a disinfectant solution such as inverted soap, and using an autoclave for high-pressure heat sterilization. Since they are all small, they are often sterilized while still in the disinfectant.

FIG. 3 is a perspective view showing a conventional example of the disinfection device, and shows a tray 1 made of stainless steel with flanges 3 formed by bending the upper ends of the left and right side walls 2 at a right angle to the outside, and a guide groove formed by bending the left and right ends. 5 and a stainless steel lid 4, each of which has small holes 6, 6' arranged at appropriate intervals. The lid body 4 and the tray 1 have approximately the same size, and by inserting the flange 3 into the guide groove 5, they are slidably fitted. And the small holes 6, 6'
are positioned so that they match each other when the lid body 4 is closed.

Further, one of the front and rear ends of the lid body 4 is bent downward to form a locking piece 7.

Note that the tray 1 has a size that allows the therapeutic needle 8 to be stored horizontally.

After sterilization, store the sterilizers together, place them on a table, and take them out one by one for use.

[The problem that the idea aims to solve]

In such a conventional disinfection device, the therapeutic needles 8 are stacked on top of each other inside the tray 1 as shown in the figure, making it difficult to take them out.

In particular, it is very difficult to pick up the needle 8 with tweezers or gloved hands because the direction of the handle 8a of the needle 8 is not consistent and it is directly attached to the bottom of the tray 1.

Moreover, if the therapeutic needles 8 overlap inside the tray 1 in this way, there is a possibility that sufficient disinfection will not be performed.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a sterilization device for root canal treatment needles, which can arrange the root canal treatment needles in an orderly manner inside a tray, does not disturb the arrangement no matter how the tray is tilted, and allows the needles to be easily taken out. It is in.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a sterilization device that combines a slidably fitted lid and a tray that stores a root canal treatment needle horizontally.
A channel is formed by parallel vertical plates in the tray, cutouts for holding therapeutic needles are formed at appropriate intervals on the upper edge of the vertical plates, and a magnet is housed between the plates at a position lower than the cutouts. The main points are as follows.

[Effect]

According to the present invention, if the therapeutic needles are placed so as to span between the parallel vertical plates in the tray through the notches in their upper edges, the needles will be arranged in parallel at intervals of the notches.
The tray is held in the notch by the attractive force of the magnet, and no matter how you tilt the tray, it will not come out of the notch and disrupt this parallel state.

In addition, to use a therapeutic needle, all you have to do is pinch the handle of the needle located on the outside of the parallel vertical plates and lift it.The needle is not in direct contact with the magnet, so it is easy to use with just a little force. It can be taken out.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the root canal treatment needle disinfection device of the present invention, and FIG. 2 is a longitudinal cross-sectional side view of the same. Reference numerals are attached.

That is, the sterilization device is the same as the conventional one in that it consists of a tray 1 and a lid 4 that slidably fits into the tray 1, and the shapes of the tray 1 and the lid 4 are also the same as in the past, so a detailed explanation will be given. Omitted.

In the present invention, two vertical plates 9 are provided in parallel in the longitudinal direction inside the tray 1, and a channel 10 is formed in the vertical plates 9, 9.

As an example, the vertical plates 9, 9 are side walls of a channel material made of stainless steel, and are fixed to such a channel material and the bottom of the tray 1 by welding. In order to avoid crushing the small hole 6 provided at the bottom of the tray 1, if the channel material is welded through the base plate 11, a space will be created between the bottom of the channel material and the bottom of the tray 1. Can be secured.

Triangular notches 12 are provided on the upper edges of the vertical plates 9, 9.
are formed at appropriate intervals. This notch 12 is for locking and holding the therapeutic needle 8 as will be described later, and the notches 12 of the opposing plates 9 are also provided at opposing positions.

Note that the height of the vertical plates 9 is slightly lower than the height of the side walls 2 of the tray 1, and the positions of the vertical plates 9 within the tray 1 are not necessarily in the center unless they are close to the side walls 2. It doesn't have to be.

A horizontally elongated permanent magnet 13 having approximately the same length and width is housed in a channel 10 formed by such vertical plates 9, 9. The height of this magnet 13 is lower than the position of the notch 12 in the vertical plate body 9. Furthermore, the magnet 13 is simply inserted into the channel 10 and is fixed between the vertical plates 9, 9 and the front and rear end walls of the tray 1, so there is no need to glue it;
It can be easily taken out by turning it upside down.

Next, how to use it will be explained.

In order to store the therapeutic needle 8 in the tray 1, the central portion of the needle 8 is placed between the vertical plates 9, 9. In this way, the needles 8 enter into the notches 12 and are arranged in parallel at intervals of the notches 12 as shown. Although the magnet 13 and the needle 8 do not come into direct contact, the needle 8 is always attracted by the magnetic force of the magnet 13 and does not easily come out of the notch 12.

When arranging the needles 8 in parallel in this way, it is desirable that the handles 8a are arranged in the same direction as much as possible. In addition, the illustrated example is a case where both a needle 8 with a large-diameter handle made of synthetic resin and a needle 8 with a small-diameter handle that is not made of synthetic resin are stored, and either type of needle 8 is stored. It can also be used for needle 8.

As described above, by placing the needle 8 horizontally in the tray 1, inserting the end of the flange 3 into the end of the guide groove 5 on the opposite side of the locking piece 7 of the lid 4, and sliding it as it is, the tray 1 will be placed in the lid 4. completely blocked. In this case, since the locking piece 7 of the lid 4 comes into contact with the front end wall of the tray 1, the lid 4 will not shift unnecessarily.

The sterilizing device of the present invention with the lid 4 completely closed is subjected to sterilization as it is, but it can be sterilized without any problem because of the small holes 6, 6' provided with the small holes 6, 6' whether it is boiled or immersed in a chemical solution.

After disinfection, slide the lid 4 and remove the handle 8.
All you have to do is pinch a and pick up the needle 8 against the magnetic force of the magnet 13. In this case, the needles 8 are arranged in parallel, and the other needles 8 other than the needles 8 to be picked up are attracted by the magnetic force 13, so it is possible to easily pick up only one needle without disturbing this parallel state.

Furthermore, if the magnet 13 is made strong, the magnetic force of the magnet 13 allows the tray 1 itself to be temporarily placed horizontally on another metal product such as a cabinet, and even in this case there is no worry that the needle 8 will fall out. .

[Effect of idea]

As described above, the root canal treatment needle sterilization device of the present invention is a sterilization device that combines a lid that can be slidably fitted and a tray that stores the root canal treatment needle horizontally. It allows therapeutic needles to be stored in an orderly manner in parallel, and as a result,
The needle can be easily taken out, and even if the needles have different thicknesses, the difference can be easily distinguished and the necessary one can be taken out quickly.

Furthermore, although the needles 8 are held in a parallel state using the magnetic force of the magnet, the needles and the magnet do not come into direct contact and can be easily taken out with a small force.

In addition, the disinfection device of the present invention can be used to organize any type of small treatment device in the form of a bar, such as air turbine bars, in addition to needles such as reamers and files, and has a wide range of versatility. It is something.
