Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention is an invention for the manufacturing field and application field of dental clamps.

(Prior art) Conventional dental clamps equipped with saliva evacuation devices are not of practical use; in other words, rubber tubes are connected to the suction holes on the buccal and lingual sides. Therefore, two rubber tubes have to be inserted into the mouth, and two rubber tubes are installed from outside the mouth, located below the buccal pressure piece and the tongue pressure piece. When it comes into contact with the caregiver's cheek and tongue, it gives a foreign body sensation and makes the caregiver feel like vomiting, making it unsuitable for treatment.

(Problems to be Solved by the Invention) It is an object of the present invention to provide a dental clamp that can be used practically without impairing the functions of conventionally used clamps, and which also has a saliva evacuation function.

(Structure of the invention) An embodiment of the invention will be described with reference to the drawings. It is composed of a clamping part 1 and a cheek pressure piece part 2. The clamping part 1 has elasticity inward and elasticity on the teeth. The tubular holding part 1a is formed by bending an elastic member such as a steel pipe or a synthetic resin pipe into a curved shape so that the holding part 1a can be held therein. (Figure 4). A connecting portion 1b is formed to protrude from a part of the connecting portion 1b, and the saliva discharge connecting pipe 41 of the connecting portion 1b is detachably connected thereto. Note that the saliva discharge connecting pipe 41 is a bendable member, and a suction pump p is attached to the tip thereof.

In the figure, reference numeral 2 denotes a cheek pressure piece, which is made of the same material as the tubular clamping part 1a, such as metal or hard synthetic resin, and has a saliva ejection tube 4 connected to the tubular clamping part 1a facing downward on the gum side. There is.

Further, numeral 3 in the figure is a tongue pressure piece part provided on the opposite side of the cheek pressure piece part 2 in the same manner as the cheek pressure piece part 2, and a saliva ejecting device is provided in the oral cavity of this tongue pressure piece part 2. Although the illustrated saliva ejecting device has a saliva ejecting tube 4 protruding downward, the present invention is not limited thereto. It may also be one with a mouth.

Are both saliva ejecting tubes 4 formed to such a length that their lower ends do not come into contact with the gums or the flesh of the oral cavity?
(Fig. 8), or it is formed into a funnel shape and its mouth edge is formed into a wave shape in the vertical direction (Fig. 8), so that saliva, etc. can be reliably discharged from the saliva ejecting tube 4. .

5 and 6 show a saliva ejector 4 provided only on the tongue pressure piece 3, and it is desirable that the saliva ejector 4 be provided at least on the tongue pressure piece 3 side.

In this way, the clamp a is attached to the tooth requiring treatment, and the pump p is operated, or at predetermined time intervals. Then, the residue or saliva generated from the dental treatment is discharged from the saliva ejecting connecting tube 41 through the saliva ejecting tubes 4, 4 and the tubular holding part 1a, thereby keeping the inside of the oral cavity clean.

In this device, the clamping portion of the clamp body is formed into a tubular clamping portion, a saliva ejection connecting tube is connected at a position approximately in the center of the tubular clamping portion, and a saliva ejection tube is provided to hang down from both ends or one end of the tubular clamping portion, so that by using a part of the clamp body as part of the saliva ejection mechanism, it has been successfully made compact, improving workability in the mouth, and since the saliva ejection tube is provided independently, saliva and the like can be removed reliably and there is no need to interrupt treatment to remove saliva and the like, making treatment efficient. Also, since the saliva ejection tube can be molded integrally with the clamp, it is easy to mold and can be provided at low cost. Moreover, since saliva can be ejected at all times, treatment can be performed accurately.

Thus, the intended purpose can be achieved.
