DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for a dental tip having a needle-like tool (for example, filing) at a tip, in other words, a cover member for covering the filing.

[0002]

2. Description of the Related Art In dental treatment, a needle-like tool (for example, a file) is used to perform scaling and filing for forming a root canal to remove plaque and tartar.
Is used.

[0003]

There are various types of tips having a needle-like tool at the tip as described above, such as for scaling, root canal formation, and subgingival irrigation. These tips have needle-like tips. Because of this, there is a risk of stabbing a hand or finger, hitting another device, or damaging another device. For this reason, these tips have needle-like tools housed in a cap (cover member) so that the needle-like tips do not hit other things.

FIG. 4 is a view for explaining an example of use of a conventional cap. In the figure, reference numeral 10 denotes a tip having a needle-like tool 11 at its tip, reference numeral 30 denotes a tip to which the tip 10 is detachably mounted. A dental instrument for applying rotation or vibration to the tip 10 to drive the needle-shaped tool 11 to perform operations such as scaling and filing. A dental instrument 20 covers the needle-shaped tool 11. As shown in the drawing, the cap 20 is formed of a cylindrical body having an opening 20a at one end, and a needle-like tool 11 is inserted through the opening 20a to cover the needle-like tool 11. The danger is prevented by preventing the needle-shaped tool 11 from hitting another object.

When the cap 20 is used as described above,
The needle-shaped tool 11 is to be inserted into the cap 20 from the tip, but in that case, if the hand gets out of order,
The hand or finger holding the cap 20 is
It was dangerous because I stabbed it with my tip. Alternatively, the tip of the needle-shaped tool 11 may be used to open the end 20 b
And the tool 11 is damaged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and in a cap for protecting a needle-shaped tool for inserting and covering the needle-shaped tool, inserting the needle-shaped tool into the cap. Sometimes a hand or finger holding the cap,
An object of the present invention is to provide a cap having a configuration in which the tip of the needle-shaped tool is not stabbed and the tip of the needle-shaped tool is not abutted against the end of the cap.

[0007]

The invention according to claim 1 is a cap for covering the needle-shaped tool of a dental tip having a needle-shaped tool at a tip portion, wherein the cap is provided from one side. A needle-shaped tool is inserted and the one side is formed of a cylindrical body fixed to the chip, and a side wall of the cylindrical body fixed to the chip has a slit extending in an axial direction, and a side extending through the slit. The tip of the needle-shaped tool can be inserted into the cap from a direction.

[0008] The invention of claim 2 is a cap for covering the needle-shaped tool of a dental tip having a needle-shaped tool at a distal end portion, wherein the cap is formed of a cylindrical member, and the cap is formed of a cylindrical member. It is characterized in that one end of the member is cut obliquely.

The invention according to claim 3 is characterized in that a slit extending in the axial direction is provided on the obliquely cut side of the cylindrical member.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a tip 10 having a needle-like tool (file) 11 at its tip (FIG. 1A) and a cap 20 for covering the needle-like tool 11 of the tip (FIG. 1
(B)) is a view showing a state (FIG. 1 (C)) when the cap 20 is attached to the tip 10 and the needle-shaped tool 11 of the tip 10 is inserted into the cap 20.

Thus, in the present invention, the cap 20
Has a slit 21 extending in the axial direction on the side wall on the side of the opening 20a, and passes the tip of the needle-shaped tool 11 in a direction crossing the slit 21 so that the cap 2
After that, the entire needle-like tool 11 is inserted into the cap 20 and fixed. In addition,
The slit 21 is opened by the fixing portion 10a when the cap 20 is inserted to the fixing portion 10a of the chip 10, and the cap 20 is formed on the chip 10 by the elasticity thereof.
It also serves to stably fix it.

FIG. 2 is a view for explaining a state when the needle-shaped tool 11 is inserted into the cap 20. FIG.
The tip of the needle-like tool 11 is the slit 2 of the cap 20
FIG. 2 (B) is a perspective view showing a state when the device is inserted into the device 1;
Is a front view of the opening of the cap 20, and FIG.
As shown by an arrow a, the tip of the needle-shaped tool 11 is passed through a slit 21 provided in
Then, as shown by an arrow b in FIG. 2A, the needle tool 11 is inserted into the cap, and the cap 20 is fixed to the tip 10.

FIG. 3 is a perspective view for explaining another embodiment of the cap according to the present invention. This cap 20 is obtained by obliquely cutting one end of a cylindrical member 20c. The tip of the needle-shaped tool can be inserted into the cylindrical member (cap) 20 from the direction of arrow a. Of course, also in this case, the slit can be stably fixed to the chip 10 by providing the slit as shown by a dotted line, for example.

[0014]

As described above, according to the present invention, the tip of the needle-shaped tool 11 is brought into contact with the opening-side end 20b of the cap 20 or the cap 20 is contacted with the tip of the needle-shaped tool 11.
Without stabbing your hand or finger
Since the needle-shaped tool 11 can be safely and securely stored in the cap 20, it is possible to prevent a risk of damaging the needle-shaped tool and stabbing a hand or finger with the needle-shaped tool. .
