2. Description of the Related Art In a tooth cutting treatment, since a cutting bar of a tooth cutting machine rotates at a high speed, tooth cutting debris may be scattered in a patient's mouth or a healer. In order to prevent tooth cutting chips or grinding chips (hereinafter collectively referred to as “cutting chips”) from scattering during the treatment of cutting or grinding teeth, a suction device for sucking tooth cutting chips has been recently used. It is used to treat teeth.

This suction machine has a dental suction tip which is inserted into the mouth of a patient. At the tip of this dental suction tip, a suction port for sucking tooth cutting waste is formed. This dental suction tip is made of metal or hard resin, and when it is made of metal, in order to prevent the dental suction tip from contacting teeth, gums, etc., to prevent them from being damaged. The tip of the dental suction tip is provided with a dental suction tip cover that covers the tip.

This suction device is used by inserting a dental suction tip into the mouth of a patient, but in order to prevent the dental suction tip tip or its cover from blocking the field of view to the cutting portion of the therapist, it is currently used. As shown in FIG. 6, the treatment is performed by placing the tip of the dental suction tip or the dental suction tip cover in the rotation axis direction of the cutting drill.

[0005]

However, when the tip of the suction tip and the dental suction tip cover are placed in the rotational axis direction of the cutting drill as described above, the tooth cutting waste is mainly in the radial direction of the rotation of the cutting drill. Since it scatters, there is a problem that it is not possible to sufficiently suck the cutting chips.

Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a dental suction tip and a cover thereof capable of sufficiently sucking cutting dust scattered during treatment. And

[0007]

In order to achieve the above object, the present invention provides a dental suction tip having a suction port provided in a suction device for sucking tooth cutting waste generated during tooth cutting treatment. In the cylindrical dental suction tip cover attached to the tip of, the constituent material is a light transmissive material.

In order to achieve the same object, the present invention also provides a dental suction tip having a suction port provided in a suction device for sucking tooth cutting waste generated during tooth cutting treatment. It is characterized in that the vicinity of the mouth is formed of a light transmissive material.

In these dental suction tips or their covers, the light transmissive material is preferably transparent.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a first embodiment of the present invention (hereinafter referred to as "first embodiment") will be described with reference to FIG. FIG. 1 is an overall perspective view of a medical examination chair equipped with a dental suction tip 14 having a dental suction tip cover 10 according to the present invention. As shown in FIG. 1, the dental suction tip 14 has a suction tube 16 attached to one side of the examination chair, and a suction tip having one end attached to the proximal end of the suction tip and the other end attached to the suction tube. Syringe 18
Aspirator body (not shown) installed in the examination room via
It is connected to the.

The dental suction tip 14 is formed in an approximately L shape as shown in FIG. 2, and is made of metal in this embodiment. A suction port 20 for sucking the cut chips is formed on the tip side of the dental suction tip 14, and the dental suction tip cover 10 is mounted so as to cover the suction port 20. The dental suction tip cover 10 is made of a transparent synthetic resin having elasticity. The distal end side of the dental suction tip cover 10 is obliquely cut as shown in FIG.

As described above, in the first embodiment, since the dental suction tip cover 10 is made of transparent synthetic resin, for example, as shown in FIG. 3, in the radial direction of rotation of the cutting drill 24, The dental suction tip cover 10 does not block the field of view of the therapist. For this reason, the tooth scraps can be sufficiently sucked while ensuring the view of the therapist. Further, as a result, since tooth cutting waste does not scatter in the patient's mouth, it is possible to prevent the tooth cutting waste from being embedded in the oral mucosa of the patient.

Further, according to the first embodiment, since the dental suction tip cover 10 can be interposed between the tooth cutting portion and the eyes of the therapist, tooth scraps scatter on the eyes of the therapist. As a result, it is possible to prevent the eyes from being injured.

Further, since the dental suction tip cover is transparent, the assistant can easily place the dental suction tip cover at an appropriate position. Further, since the dental suction tip cover is transparent, it is possible to easily confirm the stain on the inner surface of the dental suction tip cover, and it is possible to secure the hygiene aspect.

Next, a second embodiment of the present invention (hereinafter, referred to as
The "second embodiment" will be described with reference to FIG. The dental suction tip 14 of the second embodiment is made of hard synthetic resin. Therefore, the dental suction tip cover 10 is not attached to the suction port 20 of the dental suction tip 14 of the second embodiment as in the first embodiment. Unlike the first embodiment, this hard synthetic resin is not transparent with 100% transparency, but has such transparency that it does not block the visual field of the therapist. It is preferable to have a transparency of 50% or more as a transparency that does not block the visual field of the therapist. The tip of the dental suction tip 14 of the second embodiment is
As shown in FIG. 4, it is formed in a dogleg shape.

As described above, according to the second embodiment, since the tip of the dental suction tip 14 is formed in a dogleg shape, the scattered cutting chips are covered with the dental suction tip cover 10.
Even if the cutting waste collides with the upper side of and rebounds, the cutting waste collides with the lower protrusion of the dental suction tip cover and is sucked by the suction machine.

As described above, in the second embodiment, the distal end portion of the dental suction tip 14 is formed in a straight V shape, but it is not limited to this and, for example, as shown in FIG. It may be formed in a curved shape. In the present invention, as shown in FIG. 5, the length b between the most recessed portion 26 of the surface of the tip of the dental suction tip 14 on the most proximal side and the protruding tip portion 28 on the upper side of the dogleg shape. And the same recessed part 2
The ratio of 6 to the length a of the protruding tip portion 30 on the lower side of the letter I is preferably 1: 0 to 0.5. When the dental suction tip is attached as in the first embodiment,
The tip of the dental suction tip cover may be formed in a dogleg shape as in the second embodiment.

In the second embodiment, the dental suction tip 14 is entirely made of a light-transmissive synthetic resin, but the invention is not limited to this. For example, a portion that obstructs the field of view of the therapist during treatment. Alternatively, it may be formed of a synthetic resin having light transparency. For example, it may be formed of a synthetic resin having a light-transmitting property only in a portion of 2 to 10 cm, preferably 3 to 7 cm from the tip.
