Description

[Detailed explanation of the idea] Industrial applications TECHNICAL FIELD This application relates to dental hand tools.

Conventional technology Conventionally, dental hand tools such as an air turbine handpiece with a cutting bar attached to the tip head for cutting teeth, or a syringe that sprays water from the tip nozzle to clean the cutting part of the tooth are usually used. The tip of the pencil-shaped hand-held member is equipped with a head or nozzle to which a cutting bar is attached.

Problems to be Solved by the Invention However, in conventionally known dental hand tools, the entire exterior surface including the tip head or nozzle part is made of a polished metal cylinder, and the hand tool is difficult to use during dental treatment. When you hold it in your hand and place the tip head or nozzle equipped with a cutting bur into the oral cavity, the light beam of the surgical light that is turned on to illuminate the oral cavity will cause the tip head facing into the oral cavity to The reflected light often enters the technician's eyes, making dental treatment difficult and causing damage to the eyes.

Means for Solving the Problems Therefore, in order to improve the above-mentioned defects of the conventional products, the present invention is characterized in that a pear-shaped layer is integrally provided on at least the exterior surface of the portion facing the oral cavity.

Function: As in the past, the handheld device is held in the hand and the tip head or nozzle is placed in the oral cavity.
This is used for dental treatment, and since the pear-shaped layer is integrally provided on the exterior surface, the light from the surgical lamp that illuminates the oral cavity is diffusely reflected on the pear-shaped exterior, and the reflected light is difficult to see in the eyes. There is no direct sunlight.

Example Embodiments of the present application will be described in detail below with reference to the drawings.

The figure shows a dental hand tool for cutting teeth, and as is well known, this hand tool includes a neck 1' which is bent and extends forward of a pencil-shaped hand member 1.
A head 2 with a built-in air turbine is provided at the tip thereof, and a cutting bar 3 is attached to this head 2.

In the figure, from the head 2 to the neck 1'
The exterior surface is treated to have a pear-like texture, and a pear-shaped layer 4 is integrally provided thereon.

As the treatment for this matte finish, chrome plating, polytetrafluoroethylene (PIIFE) or urethane coating, or alumite treatment is suitable.

In the present application, a sufficient effect can be obtained by integrally providing at least the pear-shaped layer 4 on the head 2 facing the oral cavity, but it goes without saying that the entire hand-held member 1 may be treated with a pear-like texture. Furthermore, when the dental hand tool is a syringe, the pear layer 4 is provided on at least the exterior surface of the nozzle facing the oral cavity.

Effects As described above, since the present application is integrally provided with the pear layer that diffusely reflects the illumination light, it is possible to sufficiently eliminate the eye damage caused by the light from the surgical lamp that illuminates the inside of the oral cavity. It also has the advantage that dental treatment can be performed safely without any hindrance.
