Therefore, it is possible to prevent that the direction of the doctor unit does not go to the intended direction due to the rotation resistance of each joint, etc., and it was difficult to move it from that place to another place. became.

[0004]

[Problems to be solved by the device]

 In such a dental chair using a doctor unit, although the doctor unit is easier to use, the assistant instrument used by the dental assistant is a conventional one, and the dental assistant uses it by himself. Alternatively, it is troublesome to take an instrument to be used by the dentist, to move the dentist to move to the doctor, to move the position of the assistant instrument, or to change the direction. There was a point.

Further, although necessary for medical treatment, a doctor unit, an instrument that could not be placed on the assistant instrument, or a spare instrument is conventionally placed on a wagon with casters, Depending on the location of this wagon, it may interfere with the medical work of dentists and dental assistants, and it is difficult to move this wagon with one hand because it was difficult due to the resistance between the casters and the floor. There were also problems such as having to move it.

[0006] Such a problem is that when a dentist or a dental assistant is doing some medical treatment with one hand or has a device that is difficult to move, the medical treatment is stopped and the medical treatment is stopped. The equipment must be placed on the doctor unit or the assistant instrument, the doctor unit and the assistant instrument must be moved with both hands, the position and orientation of these must be corrected, and the equipment placed again must be picked up again. There was trouble.

The present invention relates to a means for a dental care apparatus for solving the above-mentioned problems in the conventional dental care apparatus, the means being near the front edge of a dental chair capable of undulating the backrest. Centering around the front edge of the chair and the doctor unit guided by an arc-shaped guide rail so as to pass through an arc centered on a point on the center line of the arc that passes near the back edge of the backrest when lying down An assistant instrument supported by a rotatable support arm and horizontally rotatably attached to the tip of the support arm, and is installed on the same floor as the dental chair, with one point on the rear side as the center. , And a cabinet that can be rotated in the horizontal direction.

[0008]

[Action]

 In the dental examination apparatus of the present invention, as will be described in detail in the examples below, the doctor unit can be used for standing posture with the backrest upright, supine posture with the backrest down, and treatment in the intermediate posture. By moving on a circular arc centered on a point on the plane of the dental chair, the doctor unit can be placed in the most convenient position for any medical treatment.

Further, the position of the assistant instrument is adapted to move along a circular arc centered around the front edge of the chair, and its direction can be changed. The position of the dentist can be adjusted to the most convenient position, and the cabinet can be installed on the back side of the dental chair and rotated to change its orientation. The position and the dental assistant can reach out of the position and take the appliance on or in the cabinet without moving.

[0010]

【Example】

 Next, an example of implementation of the present invention will be described below with reference to the drawings. 1 is the seat of the dental chair A, 2 is its backrest, 3 is a footrest, and the backrest 2 is laid down substantially horizontally with respect to the seat 1, and stands up to a position 90 ° from that position. On the left side of the patient sitting on the dental chair A, there is a caspida unit 4 for the patient to gargle, and the caspida unit 4 is located on the patient side. An armrest 5 is attached to the seat 1 at a height such that the elbow of a patient sitting on the seat 1 hits the armrest 5.

In this dental chair A, an arcuate rail 7 having a center point α is provided on the rear side of the seat 1 on the side opposite to the side on which the doctor unit 6 is installed. A movable base 11 to which rollers 8 and 9 which can roll and rollers 9 and 10 which roll on both side surfaces of the rail 7 are mounted is moved on the rail 7 by the rolling of the rollers 8, 9 and 10. It can be moved freely and the movable table 11 is prevented from tilting.

An arm 12 is fixed to the movable table 11, the arm 12 extends obliquely upward, and a doctor unit 6 is fixed to the upper end of the arm 12, so that the doctor unit 6 has an arc of a rail 7. Although it moves concentrically with an arc a larger than the arc of the rail 7, the angle with respect to the arc a does not change.

The change in the moving position and the direction of the doctor unit 6 is shown as X _{1 to} X ₅ in FIG. 1 and the directions of the doctor unit 6 at X ₁ and X ₅ at that time are shown. As is clear from this figure, the dentist treats the patient from one side of the doctor unit 6, while the orientation and position of the doctor unit 6 are different depending on the patient's standing posture, supine posture, and intermediate postures. It will be the most suitable position for medical treatment.

On the other hand, a rotatable arm 13 extends obliquely outward and upward from the center point around a point substantially coinciding with the center point α of the rail 7 on the rear left side of the seat portion 1, and An assistant instrument 14 is rotatably attached to the upper end of the assistant instrument 14. Therefore, the assistant instrument 14 can move along an arc centered on the center point α and can move in any direction from the moved point. It can be directed to.

In FIG. 1, Y _{1 to} Y ₄ indicate the movable position of the arm 13 based on the above, and also indicate the optimum orientation for the work of the dental assistant of the assistant instrument 14 at each point. The position and orientation of this assistant instrument 14 correspond to the position and orientation of the dentist for the treatment of the patient's upright posture and supine posture, and at the same time, the assistant instrument 14 assists the medical treatment toward the patient. It is also the best for taking the above equipment.

Further, the cabinet body B is fixedly installed on the floor surface on which the dental chair A is installed, on the back side of the dental chair A. The cabinet body B has a sink 15 and A faucet 16 and the like are provided so that the dentist can wash his / her hands after finishing the medical treatment. A support shaft 17 is provided on the front left side of the cabinet body B, and the support shaft 17 serves as a fulcrum β. As an example, the left side behind the rotary cabinet 18 in which the doctor unit 6, the tools that could not be placed on the assistant instrument 14, or spare tools is stored is pivotally supported.

Therefore, when the dentist performs medical treatment in the supine posture, both the dentist and the dental assistant are at the positions of X ₄ , X ₅ and Y ₃ , Y ₄ which are close to the cabinet body B. Therefore, the instrument can be taken out without rotating the rotating cabinet 18, but both the dentist and the dental assistant keep away from the cabinet body B when performing the medical examination in the standing posture. By rotating about the β point of, the distance is compensated, and if the dentist extends the hand as shown in the figure, the rotation cabinet 18 can be reached.

It is desirable that a handle 19 be provided on the rotating cabinet 18 so that the rotating cabinet 18 can be easily rotated by gripping the handle 19. The armrest 5 provided on the side surface of the caspida unit 4 facilitates keeping the patient's gargling posture by sitting on the dental chair A or placing the elbow on the gargle.

[0019]

[Effect of the device]

 In the present invention, as in the above, the doctor unit only moves on the arc-shaped rail and moves on the arc centering on one point of the dental chair. Since the number of joints that support the joint is small, it is possible to eliminate the difficulty of moving to the desired position due to the difference in turning characteristics based on the difference in the friction coefficient of this joint, and the doctor unit must be operated with both hands. You can eliminate the hassle that was not there.

Similarly, since the assistant instrument only needs to rotate around a point on the dental chair and rotate at the rotation destination, it is easy to move to the desired position as with the doctor unit. Not only that, but by changing its orientation, it is possible to work well with a dental assistant and to work with a dentist, and to operate the assistant instrument with one hand.

[0021] Since the doctor unit, the equipment that could not be placed on the assistant instrument, and the cabinet that stores the spare equipment can be rotated about a single point on the rear of the cabinet, the rotation position of the patient can be changed. By adjusting to the medical treatment situation such as the medical treatment in the standing posture and the supine posture, both the dentist and the dental assistant can reach the instrument in this cabinet without moving much from the treatment position. As it arrives, various problems associated with moving during medical treatment are resolved.

Moreover, by constructing the cabinet in this way, a wagon with casters, on which a doctor unit, an instrument that could not be mounted on an assistant instrument, and a spare device, which were conventionally mounted, are unnecessary. The problem that the wagon was hindering in medical treatment can be solved, and it is possible to change the wagon that was difficult to move and turn with one hand into a cabinet that can be operated with one hand.

The advantages of these doctor units, assistant instruments, and cabinets effectively interact with each other in the dentist's and dental assistant's dental examination work, thereby improving the work efficiency of the dental examination and reducing the examination space. It has the effect that it can be achieved.
