Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dental lighting device and an automatic tracking device for a table, and in particular, a chair on which a patient is placed for treatment, a lighting device for illuminating an affected area, and a device for mounting a treatment device. In a dental treatment unit having a table part for patients to gargle, a spittoon part for patients to gargle, etc., the chair, lighting equipment, and table part are configured to be moved to predetermined positions, and During the automatic setting operation, the lighting fixture 1 and the table part also follow and move to a preset position, and as soon as the lighting fixture reaches the set position, the light turns on, and the chair returns to the specified position. return to the initial position, at the same time the light goes out, and then the lighting fixture and the table part return to the predetermined initial position, thereby linking the series of operations of the treatment chair, the lighting fixture, and the table part. The aim is to improve the operability of the machine and make the treatment more efficient.

In dental treatment units, it is already known that the treatment chair is automatically moved to a preset position by operating a single button switch. When performing dental treatment facing the dentist, the lighting equipment and the table must be placed in a certain position, but currently, the operator (doctor) operates these lighting equipment and the table by hand. In most cases. Additionally, the treatment chair can be returned to its initial position by operating an automatic return button switch, but in this case, the surgeon or assistant must manually operate the lighting equipment and table. I was trying not to hit the chair that was automatically returning to its original position, or the patient sitting on the chair. As described above, in conventional dental treatment units, although the treatment chair is automatically controlled, the lighting equipment and table still have to be operated by hand, making operability extremely difficult. It was bad.

The invention was made in view of the above-mentioned circumstances.
In particular, in response to the movements of conventional chairs, such as the movement of the chair up and down, the undulation of the backboard, auto-return, memory settings, etc., the lighting equipment and table section are also operated in conjunction with the movements of the chair as Is movements of the chair. , thereby improving the operability of the dental treatment unit and increasing the efficiency of the treatment.
be.

The figure is an overall configuration diagram for explaining one embodiment of the present invention, in which 10 is a central control unit, 30 is a chair vertical movement control unit, and 30
is a chair elevation control section, 40 is a lighting equipment control section, a leap is an operation switch section, a gloss is a light on/off switch, 70 is a table section control section, M is an automatically controllable motor or cylinder, R is the motor or A position sensor such as a potentiometer, a magnetic sensor, an optical sensor, or a rotary encoder is connected to the cylinder, and as shown in the figure, the motor M and the potentiometer R are connected to at least one joint part of the moving mechanism of the illumination light 41 and the table 71. attached. Since the height and degree of undulation of the treatment chair vary depending on the body shape of the surgeon, it is first necessary to determine the position of the chair that suits the body shape of the surgeon, and this position is first stored in the memory of the central control unit. let This memory setting operation is
First, use switches 5W51 and 5W52 to lower the chair to the desired height, and use switches SW53 and 5W54 to adjust the back of the chair to the desired degree of undulation. The table section is manually set to the most convenient position for diagnosis, and in this state, the memory storage switch 5W58 is pressed to store it in a predetermined memo 'J- (RAM) in the central control unit 1o. That is, when the upper and lower positions of the chair, the ups and downs of the backboard, and the positions of the lighting equipment and table are set to the desired states as described above, each state position is detected as a voltage value by each potentiometer, and this voltage value is D converted, memory storage switch 5w
When 58 is pressed, the nuclear A/D converted values are stored in the memory of the central controller 1o. In this way, the optimal positions of the treatment chair, lighting equipment, and table section are determined. Once stored in the memory, when the switch 5w57 is pressed, each motor is driven so that the current value of the potentiometer becomes the value stored in the memory, and the up and down positions of the chair, the up and down position, and the lighting equipment are controlled. The position of the table section, etc. are all automatically set to the positions stored in the memory as described above, and at the same time, the light 4
1 is lit. Note that this light 11 can also be turned on and off manually using a light on/off switch 6o. Also, auto return switch 5W
The light 41 is turned off by pressing 56, and then
Limit switch SW2 in the initial state of the chair (lowest position)
Return it to □, and at the same time turn the lighting equipment on to the limit switch SW.
4□, return the table section to limit switch SW7□ to set it to the initial state. Note that during the auto-set and auto-return operations described above, it is natural to ensure that the lighting equipment and table do not hit the chair or patient. When setting up the A/D conversion value of the back plate, the A/D number of the lighting equipment, and the A/D number of the table part for the rising direction.
The D numbers are compared, and if there is a hit area, the lighting equipment and table section can be controlled to return to the area where the hit area is not hit.

As is clear from the above description, according to the present invention, the lighting equipment and table section are operated in series in conjunction with the movement of the treatment chair, which greatly improves operability and increases treatment efficiency. be able to.
