Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental treatment apparatus equipped with an ultrasonic cleaner which can easily and reliably clean dental treatment instruments such as dental grinding bars, files and scalers attached to handpieces. Regarding

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
The used grinding bar, reamer, scaler, etc. attached to the tip of the handpiece in dental treatment are
For example, one day's worth was put together in a heat sterilizer and sterilized. However, in general, the bar, file, reamer, scaler, etc., are not replaced after use and are used for the dental treatment of the next patient as they are, so that the disease transmission between the patients cannot be prevented.

[0003]

SUMMARY OF THE INVENTION The present invention is to solve the above problems, that is, in a dental treatment apparatus comprising a patient seating chair, an illuminating lamp, a dental treatment instrument mounting bracket table, and the like, The dental treatment apparatus is provided with an ultrasonic cleaning device, wherein the ultrasonic cleaning device is recessed in the bracket table for mounting the dental treatment device. Since the ultrasonic cleaner is recessed in the bracket table, the grinding bar, reamer, etc., which is usually removed from the handpiece above the table, is placed in the concave cleaning tank of the ultrasonic cleaner near the operation location. The ultrasonic cleaning work can be executed simply by throwing in and pressing the operation switch of the cleaning device. According to the ultrasonic cleaning tank of the present invention, the ultrasonic cleaning vibration applied removes and cleans the dirt adhering to the surface of the grinding bar 30 by the emulsification, agitation, dispersion, etc. due to the vibration. The sonic vibration destroys and sterilizes most Staphylococcus, Streptococcus, Sperochetes, Escherichia coli, Salmonella, etc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the dental treatment apparatus of the present invention will be specifically described below with reference to the drawings. FIG. 1 shows a perspective view of a dental treatment apparatus equipped with an ultrasonic cleaning apparatus according to an embodiment of the present invention, FIG. 2 is an enlarged sectional view of an essential part, and FIG. 3 is an exploded view of the essential part. In FIG. 1, reference numeral 1 denotes a dental treatment chair on which a patient 2 is seated. The dental treatment chair 1 includes a treatment table seat 3, a backrest 4 tiltably attached to the treatment table seat 3, and a tip portion of the backrest 4. And a headrest 5 disposed on the. The elevating device 6 mounted below the treatment table sheet 3 allows the patient to easily get on and off the treatment table sheet 3, and the treatment table sheet 3 is moved up and down so that the posture of the operator during treatment is not unreasonable. It is to raise and lower to an appropriate position. Around the dental treatment chair 1, a spittoon unit 7 is provided as a water supply / drainage facility so that the patient can rinse the mouth at the start and end of the dental treatment, and is formed integrally with the spittoon unit 7. An illumination lamp 10 for illuminating the affected oral cavity from above is provided, which is supported by the illumination lamp pole 8 and the arm 9. And
Arm 1 formed in series with the spittoon unit 7
1 is provided with a bracket table 15, and the work tray 1 is provided on the bracket table 15.
2, dental treatment instruments such as the burner 13 and the handpiece 14 are placed. A grinding bar 30 is attached to the tip of the handpiece 14. Further, the bracket table 15 has an X-ray film viewer 1 at its rear end.
6 are erected. Further, a drive control box 17, etc. for driving and controlling the dental treatment chair 1, the spittoon unit 7, the illumination lamp 10, the table base 15 and the like are arranged.

In the present invention, the ultrasonic cleaner 20 is recessed on the bracket table 15, and the grinding bar 30 used by the operator is attached to the tip of the handpiece 14.
Can be removed and immediately put into the cleaning tank of the ultrasonic cleaner 20 at the closest position. The detailed structure of the ultrasonic cleaner 20 is shown in FIG. 2 which is a sectional view of the mounted state and FIG.
That is, in the figure, 20 is an ultrasonic cleaner, 200 is an ultrasonic vibrator, 200a is a lead wire, 201 is an ultrasonic cleaning tank, 2
02 is a cleaning tank cover, 203 is a silicone resin ring, 2
04 is a cleaning tank receiver, 205 is a cap, 206 is a contact, 2
Reference numeral 07 is a net basket, and 207a is a net basket handle. 21 is a cleaning tank protection cylinder, 22 is a switch button, and 23 is LE
D, 24 is an AC power supply, 25 is a controller, 26 is a spring electrode,
26a is a lead wire, and 27 is a support plate. The grinding bar 30 put in the basket 207 of the ultrasonic cleaning tank 201
On the other hand, ultrasonic vibration is transmitted through the cleaning liquid 208 to perform the cleaning. In this example, the ultrasonic vibration with a frequency of 80 to 120 kHz is the ultrasonic vibrator (PZ
T ceramic oscillator) 200.

[0006] According to the ultrasonic cleaning vibration, dirt adhering to the surface of the grinding bar 30 is removed and cleaned by emulsification, agitation, dispersion, etc. by vibration. In addition, the application of this kind of ultrasonic vibration has an advantage of destroying and sterilizing a large number of germs such as staphylococci, streptococci, sperochetes, Escherichia coli, and Salmonella.

[0007]

As described above in detail in the embodiments and the like, according to the device of the present invention, the grinding bar, reamer, scaler, etc., which are removed from the handpiece etc. above the bracket table, are located at the positions immediately adjacent to the operation positions. By simply throwing it into the cleaning tank of the recess ultrasonic cleaning device and pressing the operation switch of the cleaning device, the ultrasonic cleaning work of the grinding bar and the like is performed, and hygiene management can be easily performed. Also, since ultrasonic cleaning sterilizes pathogenic bacteria such as staphylococci, streptococci, sperochetes, salmonella, etc., it is possible to prevent the transmission of diseases between patients, doctors and nurses, which greatly contributes to the field.
