Abstract

PROBLEM TO BE SOLVED: To provide a nozzle chip for tooth surface cleaning with which even a fine part such as a part between teeth can be effectively cleaned. SOLUTION: This nozzle chip 10 is used by being freely attachably and detachably mounted on a tooth surface cleaning hand piece provided with an air circuit, a water circuit and a freely attachable and detachable powder tank housing powder for tooth surface cleaning in the air circuit. The air circuit and the water circuit inside the hand piece are both opened, air containing the powder and water are jetted from the tip of the nozzle chip 10 and a tooth surface is cleaned. The nozzle chip 10 is composed of the double pipe of an inner pipe 11 for jetting the air and an outer pipe 12 for forming a clearance with the inner pipe 11 and jetting the water from the clearance and the inner pipe 11 of a small diameter is extended forwards more than the outer pipe 12 at a tip part. Side holes 11b are provided on the outer wall part 12 of the tip part outer periphery of the inner pipe 11 as well and powder air is jetted also in a radial direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tooth surface which is detachably mounted on a tooth surface cleaning handpiece, and from which a powder (powder) for tooth surface cleaning is mixed with air and water and injected. The present invention relates to a nozzle tip for cleaning.

[0002]

2. Description of the Related Art FIG. 2 is a schematic overall perspective view for explaining an example of a tooth surface cleaning handpiece to which a nozzle tip according to the present invention is removably mounted and used.
Denotes a nozzle tip, 20 denotes a handpiece part, 30 denotes a powder surface cleaning powder (powder) storage tank detachably mounted on the handpiece part 20 in a cartridge manner, and 40 supplies air and water to the handpiece part 20. In the instrument hose, the nozzle tip 10 is, for example, as shown in an enlarged manner at the tip thereof, as shown in FIG.
Is formed of a double pipe consisting of an inner pipe 11 forming a nozzle for injecting the inner pipe, and an outer pipe 12 concentric with the inner pipe 11, and is operated from a well-known foot switch (not shown) to be injected from the inner pipe 11. A containing powder, inner tube 11 and outer tube 1
And mixed with water A injected from the gap between 2 and injected,
Clean tooth surfaces.

[0003]

The discharge range of the above-mentioned conventional tooth tip cleaning nozzle tip is about 2 mm, which is sufficient if it is used for cleaning only the tooth face. When it is used in a thin part such as a part adjacent to a tooth, it is difficult to aim, and there is a problem that the powder does not enter the target part well.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and provides a tooth tip cleaning nozzle tip capable of reducing the diameter of a powder injection nozzle and effectively cleaning even a small portion. It was made for the purpose of providing.

[0005]

According to a first aspect of the present invention, there is provided an air circuit and a water circuit, and a powder tank for accommodating a powder (powder) for cleaning the tooth surface is detachably provided in the air circuit. A nozzle tip used detachably attached to a tooth surface cleaning handpiece, wherein both the air circuit and the water circuit in the handpiece are opened, and air and water containing the powder from the tip of the nozzle tip. In a nozzle tip for a tooth surface cleaning handpiece for cleaning a tooth surface by spraying a spray consisting of: an inner pipe for injecting the air, and a gap between the inner pipe and the inner pipe to form the gap. It is characterized by comprising a double pipe with an outer pipe for spraying the water, wherein the inner pipe extends forward from the outer pipe at a tip end.

According to a second aspect of the present invention, in the first aspect of the present invention, the inner tube has a distal end formed in a stenosis hole and an opening formed in a peripheral surface extending from the outer tube. It is what it was.

[0007]

FIG. 1 is an overall perspective view of a nozzle tip 10 suitable for use by being attached to a tooth surface cleaning handpiece 20 as shown in FIG.
It is used in the same manner as the nozzle tip 10 shown in FIG. 2, but in the present invention, the distance L between the distal end of the inner tube 11 and the distal end of the outer tube 12 is configured to be long. The tip portion of the nozzle tip 10 can be configured to have a small diameter, and this small diameter configuration can penetrate into a narrow portion such as between teeth, so that powder can be effectively applied.

The distal end of the inner tube 11 is
a is provided, and an opening 11b is provided in the extension peripheral portion. The powder is accelerated by the stenosis opening 11a so that the tooth surface can be more effectively cleaned, and a fluid is provided inside the inner tube 11. The inner tube 11 is inserted into the interdental portion or the like by generating resistance and injecting powder from the peripheral opening (lateral hole) 11b.
By spraying also from 1b, the powder can be applied to a portion where the powder is difficult to apply with the conventional nozzle tip.

[0009]

As is apparent from the above description, according to the present invention, the nozzle tip for cleaning the tooth surface has a double-pipe structure including an inner pipe and an outer pipe, and at the tip of the nozzle tip,
By taking a large difference in length between the inner pipe through which the powder air inside passes and the outer pipe through which water as the outer pipe passes, the inner pipe with a small diameter at the tip of the nozzle tip is made longer than the outer pipe. Since it is made to extend, the tip of the inner tube can be made to penetrate into a finer portion, and powder can be applied. Also, several holes (lateral holes) are made on the outer periphery of the outer wall at the tip end of the small-diameter inner tube through which the powder air passes, and the inner tube is inserted into a narrow portion such as the interdental portion and the powder is injected from the side hole. Thus, it is possible to apply powder to a portion where powder application is usually difficult.
