Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for sucking saliva, washing water, blood, chemicals, moisture and the like in an oral cavity and cleaning and drying a root canal during dental treatment.

[0002]

2. Description of the Related Art A vacuum device used for dental treatment is designed to insert a nozzle at the tip into an oral cavity to suck saliva, water, cutting powder, etc., but does not move the nozzle around a tooth. In addition, it is not possible to sufficiently absorb moisture and the like, and such operation cannot be performed by one person at the same time as cutting teeth.

For this reason, the present inventor has proposed a device which allows a flexible and shape-retaining suction tube to be attached along the dentition in the oral cavity (Japanese Patent Application No. Hei 6-3646).
issue). This device has excellent performance that is easy to wear and can be used without the need for an assistant.

[0004]

By the way, when performing root canal treatment or root canal filling after removing a nerve of a tooth, a cotton or a paper point is inserted many times to remove foreign matter in the root canal, and to clean and dry. After that, filling is performed using a rattle aperture or the like.
This work is very time-consuming, but for example, the current vacuum device is a single nozzle, so it is not possible to suck the root canal at the same time as sucking around the teeth, and blowing compressed air into the root canal It is dangerous because emphysema may occur.

It is an object of the present invention to provide a device which can protect the outer surface and the periphery of a tooth from moisture while simultaneously sucking and drying a root canal.

[0006]

In order to solve the above-mentioned problems, according to the present invention, one end or both ends of a hollow tube having flexibility and shape retention are connected to a base, and a small suction tube is provided at an appropriate position of the tube. A hole was provided, another flexible tube was connected to the base, and a hollow suction needle was provided at the tip of the tube, so that the base could be connected to a vacuum device.

[0007]

[Function] When the above tube is attached along the periphery of the teeth, the tube is flexible and has shape retention properties.
The tube can hold that state.

Therefore, when the mouthpiece protruding outside the oral cavity is connected to the hose of the vacuum device, saliva and the like can be sucked from the small holes for suction, and at the same time, the inside of the root canal can be sucked and dried by the suction needle. it can.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a dental suction device 1 of the present invention comprises a flexible and shape-retaining loop tube 2, a base 3 connected to the loop tube 2, and a base 3 Flexible tube 4 extending from
The loop tube 2 has a small hole 2a for suction.
Are provided, and the spacer 5 is fixed to the tip.

As means for making the loop tube 2 flexible and having shape-retaining properties, for example, as shown in FIGS. 1 to 3, copper, aluminum, silver and the like are contained in a flexible tube 2 made of rubber or synthetic resin. For example, there is a method of inserting a wire 2b having shape retention properties. The wire 2b does not necessarily need to extend over the entire length of the tube.
For example, as shown in FIG. 5, the wire 2b may be inserted only into a portion of the tube 2 where a loop is formed.

As another means for imparting shape retention, FIG.
As shown in (1), there is a method of forming fine bellows 2c on a tube 2 made of a semi-rigid synthetic resin. The bellows 2c may be formed over the entire length of the tube 2, or may be formed only at the loop portion or other bent portions.
Further, a metal wire 2b having shape retaining properties can be used in combination. Further, a spiral spring wire may be inserted and fixed inside at the same pitch as the bellows 2c.

The material of the base 3 is not limited, such as synthetic resin or metal, but the connection port 3a is preferably tapered in consideration of the convenience of connection with the vacuum device. A hollow tube 4 different from the loop tube 2 is connected to the base 3. The hollow tube 4 is made of a flexible and flexible material such as rubber or synthetic resin, and has a hollow suction needle 4a provided at a tip thereof. This hollow suction needle 4a
It is inserted into the root canal of a tooth to suck and dry moisture and the like, and is bent in a letter shape to facilitate the operation.

A spacer 5 is attached to the tip of the loop tube 2. The spacer 5 includes a stopper 5a formed by bending a stainless steel wire into a U-shape, a coil-shaped portion 5b formed by a spring wire, and a contact portion 5c having a U-shaped tip. And the stopper 5a
The base 5d is inserted into the loop tube 2 to support the stopper 5a, and a coil-shaped portion 5b extending from the contact portion 5c is inserted into a middle portion of the stopper 5a so that the contact portion 5c is 5a can be elastically approached or separated.

An example of use of the suction device 1 will be described with reference to FIGS.

First, the loop tube 2 is brought into close contact with the teeth A along the outer periphery of the dentition B in the oral cavity A. Since the tube 2 is flexible and has shape retention properties, the tube 2 can be easily brought into close contact with the teeth B.

Then, the spacer 5 is applied to the upper teeth and bite lightly. Thereby, the position of the tube 2 can be stabilized, and the state in which the mouth A is opened can be easily maintained.

When the portion of the tube 2 led out of the oral cavity A is appropriately bent, the connection port 3a of the base 3 is connected to the hose D of the dental vacuum apparatus, and when the vacuum apparatus is operated, the small hole for suction is obtained. Saliva and the like are sucked from 2a.

At this time, since the tube 2 is interposed between the tongue C and the dentition B, the tube 2 blocks the tongue C and prevents the cutting tool from damaging the lips, cheeks, etc. in addition to the tongue C. it can.

Then, the suction needle 4a of the tube 4 is inserted into the root canal to dry the root canal wall. Also, the suction needle 4a
When is not used, the suction needle 4a may be hung from the base 3 without any hindrance to the treatment, and the suction needle 4a has a small inner diameter (about 0.5 mm), so that the vacuum is not lost.

[0021]

According to the present invention, as described above, a small hole for suction is provided in the hollow loop tube having flexibility and shape retention, and this tube is connected to the base, so that the tube can be easily formed along the row of teeth. Can be worn in the oral cavity, and the worn state can be maintained as it is by shape retention, so that treatment can be performed without an assistant. Then, another tube is connected to the base, and a suction needle is connected to the tip of this tube, so that saliva, water, cutting powder, etc. are removed by suctioning around the teeth with the loop tube, and at the same time, the root canal is removed. Since the root canal wall can be dried by inserting a suction needle into the inside, the trouble of cleaning the paper many times at a paper point or the like can be omitted, and the existing device can be used as it is without requiring a separate vacuum device. .
