The method for using dental reamers and files is relatively simple: pick the handle with your fingers, insert the reamer or file blade at the tip of the handle into the root canal, and repeat back and forth rotation. Through this operation, pathogenic substances within the root canal are completely removed and the shape of the root canal is adjusted, allowing complete root canal filling.

のが一般的と成つていた。 In addition, when using the reamer and file as described above, the optimum unit cutting degree, that is, the maximum step rotation angle, is generally considered to be approximately 1/4 turn, but conventional manual operation Regarding dental treatment tools such as reamers and files,
As shown in FIGS. 1A and 1B, the handle 20 to which the blade 10 is attached generally has a substantially cylindrical shape.

However, because the handles of conventional dental treatment instruments have a substantially cylindrical shape, they may be rotated more than necessary during operation, shortening the life of the dental treatment instrument and causing damage, or causing unnecessary damage to the root canal. There was a lurking danger that this would cause serious problems in dental treatment, such as the formation of steps or perforations.
もし仮りに、リーマーやフアイルが根管内で破
損してその破片が根管内に残留した場合、その除

の外科的手術を要する場合もあつた。 If the reamer or file were to break in the root canal and its fragments remained in the root canal, it would be extremely difficult to remove them, and surgical operations such as root resection or tooth extraction would sometimes be required.
本考案は、上述の問題を解決し、過度の回転を

The purpose of the present invention is to solve the above-mentioned problems and provide an excessive rotation prevention structure that does not have the risk of excessive rotation and can always confirm the correct rotation amount and rotation angle. The handle of root canal enlargement instruments such as files or cleaning instruments,
This can be achieved by forming a square prism shape with one side wide enough to be easily detected by touch with fingers.

The device for preventing excessive rotation of root canal enlargement and cleaning instruments in dental treatment according to the present invention can be applied by pinching the handle of the root canal enlargement instrument or cleaning instrument, such as a square prism-shaped reamer or file, with your fingers. , the rotation unit angle of 90 degrees can be reliably grasped by touch.
以下、図面に基づいて本考案の一実施例を説明
する。
Hereinafter, one embodiment of the present invention will be described based on the drawings.
第２図において、１はリーマーあるいはフアイ

ないしはテーパ形ワイヤに捻りを加えて形成され
ている。 In Fig. 2, 1 is a reamer or file blade, which is a tapered wire with a polygonal cross section;
Alternatively, it is formed by twisting a tapered wire.
そして、２は前記刃部１の基部に取付けられて

れ、回転状態を的確に把握できる。 Reference numeral 2 denotes the handle of the present invention attached to the base of the blade 1, and is formed into a regular square prism shape with one side wide enough to be easily detected by touch with the fingers. Therefore, when using the device, if you use your fingers to pinch the two opposing sides of the handle 2 and rotate it back and forth, as in the conventional way, the fingertips will have a quarter rotation, or each side of each side, every 90 degrees. The rotational movement can be felt as a tactile sensation, and the rotational state can be accurately grasped.
尚、前記の柄部２の表面にシリコンゴム等の人
間の皮膚感触に近い弾性素材をコーテイングする
ならば、操作時の滑り感がなくなり更に確実な操
作が行なえるようになる。 Incidentally, if the surface of the handle portion 2 is coated with an elastic material similar to the feel of human skin, such as silicone rubber, the slippery feeling during operation will be eliminated and more reliable operation will be possible.
