フアイル等の器具における柄部構造に関する。[Detailed description of the invention] This invention is a dental reamer used when performing pulp extraction and root canal formation of an infected root canal in dental treatment, and a dental reamer used for cleaning the root canal wall after root canal formation and correcting and enlarging the curvature of the root canal. This invention relates to the handle structure of instruments such as dental reamers and files used.

段が待たれた。 However, in conventional instruments of this type, the handle 20 to which the blade member 10 is attached is made of metal or a hard synthetic resin material, as shown in FIGS. Because the diameter of the root canal must be small for functional reasons, it is easy to rotate excessively, and it also tends to slip when moisture adheres to it, resulting in damage due to fatigue of the material, formation of steps in the root canal, or perforation. Kitasu etc.
This may also cause serious problems in treatment. If the reamer or file is damaged and left in the root canal,
Removal is extremely difficult and may require surgical procedures such as root resection or tooth extraction, and a solution to this problem has been awaited.

提供することを目的とする。 This invention improves the handle, which is the base point for rotating the reamer and file, to prevent excessive rotation, prevent erroneous operation due to slipping, etc., and allow rotation operation while confirming the required rotation angle by feeling with the fingers. Root canal enlargement in dental treatment that will not cause damage to the reamer and file due to rotation, or malfunction due to slipping, resulting in formation of steps, perforations, etc., which are extremely difficult to remove or repair in dental treatment. The purpose of the present invention is to provide a handle structure for a cleaning device.

る。 The structure of the present invention is for root canal enlargement and cleaning in dental treatment, characterized in that the handle of root canal enlargement and cleaning instruments such as reamers and files is coated with silicone rubber that is close to the human cortex and has excellent adhesion. This invention relates to the structure of a handle of a cleaning instrument, and will be described below based on an embodiment shown in the drawings.

にて被覆されている。 In FIG. 2, reference numeral 1 denotes a reamer and file blade member, which is formed by twisting a tapered wire or a tapered wire having a polygonal polygonal cross section. Reference numeral 2 denotes a handle of the present invention attached to the base of the blade member 1, and in this embodiment, a silicone rubber 3 which is close to the human cortex and has adhesive properties is used.

る。 The shape of the handle is 1/4 as shown in Figure 2 A.
The handle may be of any shape, such as a quadrangular prism-like handle that is rotated one by one to provide an effect of preventing excessive rotation, or a cylindrical handle as shown in FIG. 2B. In the case of the one shown in Figure 2 A, since it fits the fingers and can transmit the touch of the fingers, it is possible to exhibit an even more reliable effect of preventing excessive rotation. However, according to the present invention, a suitable excessive rotation prevention effect can be exerted as well.

る。 However, according to the present invention, the diameter has to be small due to its function and rotational operation, and although the rotational operation requires careful attention and high skill, it is possible to use metal without devising ways to prevent excessive rotation. The handles of conventional reamers, files, and other instruments used for enlarging and cleaning root canals made of soft or hard synthetic resin are coated with silicone rubber, which is close to the human cortex and has excellent adhesion. , since it fits closely to the fingers and can transmit the feel of the fingers, it can fully demonstrate the effect of preventing excessive rotation, and it can be rotated safely and reliably at the desired angle, preventing damage to reamers and files due to excessive rotation. The root canal can be enlarged, and the tooth root canal can be cleaned and enlarged without any unforeseen accidents such as perforation caused by erroneous operation due to slipping or the like.
