Description

  The present invention relates to a dental treatment unit, and more particularly to a dental treatment unit that drives and controls one of a plurality of dental treatment instruments in accordance with an operation of an operator.

  FIG. 4 is an overall configuration diagram showing an example of a dental treatment unit to which the present invention is applied. The illustrated dental treatment unit includes a treatment chair 1, a work table 2, a spitton 3, a surgical light 4, an instrument holder 5, an instrument 6, a foot switch 7, a display 8, and the like. In the dental treatment, the patient sits on the treatment chair 1 and receives treatment with his head fixed to the cradle. During the treatment, the surgeon moves the treatment chair 1 up and down, tilts and tilts to make it easy to treat the patient.

  In the dental treatment unit as described above, the instrument holder 5 is equipped with various dental treatment instruments 6 such as an air turbine, a micro engine, a syringe and the like as is well known. 6 is pulled out from the instrument holder 5 and used. At that time, the pulled-out instrument 6 is detected by using a light sensor, a pressure sensor, or the like provided in the instrument holder 5, and a power source or the like related to the pulled-out instrument 6 is selected. Making the instrument 6 into a usable (driveable) state is performed (for example, refer to Patent Document 1).

  However, the above-described prior art cannot be used unless it is a device provided with the above-described instrument holder, and even if the device is provided with an instrument holder, the instrument is an instrument holder. There is a problem that the instrument to be driven is not changed unless it is surely returned.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a dental treatment unit capable of more accurately driving an instrument held by an operator.

  In order to solve the above-described problem, a first technical means of the present invention includes a plurality of dental treatment instruments and a switch for driving and controlling one of the instruments according to an operation of an operator. An imaging unit that images the vicinity of the patient's face, an image recognition unit that performs image recognition processing on the image captured by the imaging unit, and detects the instrument A control unit that selects one of the instruments detected by the image recognition unit and drives and controls the one instrument according to an operation on the switch. .

  According to a second technical means of the present invention, in the first technical means, the imaging unit is provided in a microscope for magnifying the inside of the oral cavity of the patient.

  According to the dental treatment unit of the present invention, an instrument held by an operator can be more accurately driven.

It is a block diagram for demonstrating an example of the dental treatment unit by this invention. It is a figure which shows an example of the image imaged by the imaging part of the dental treatment unit of FIG. It is a figure explaining the other example of the dental treatment unit by this invention. It is a whole block diagram which shows an example of the dental treatment unit to which this invention is applied.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following description, the configurations denoted by the same reference numerals in different drawings may be omitted because they are of the same type.

FIG. 1 is a block diagram for explaining an example of a dental treatment unit according to the present invention. FIG. 2 is a diagram illustrating an example of an image captured by the imaging unit of the dental treatment unit of FIG.
The dental treatment unit of FIG. 1 includes a plurality of dental treatment instruments 6, an instrument holder 5, a foot switch 7, a display 8, and the like. The instrument holder 5 of this dental treatment unit does not have a sensor for detecting the instrument 6 pulled out from the holder 5. However, by having the following configuration, it is possible to make the instrument held by the surgeon a more accurate driving target. In the following, it is assumed that the plurality of instruments 6 have heads having different external shapes.

The dental treatment unit includes a control unit 11, an imaging unit 12, and an image recognition unit 13.
The controller 11 controls each part of the dental treatment unit.
The imaging unit 12 images the vicinity of the face of the patient sitting on the treatment chair 1 (see FIG. 4). The imaging unit 12 is provided at a position where the inside of the patient's mouth can be imaged, for example, the operating light 4 or the arm 4 a that supports the operating light 4.

The image recognition unit 13 performs recognition processing on the image I captured by the imaging unit 12 as illustrated in FIG. 2, and detects the instrument 6 located in the image I among the plurality of instruments 6. Since the plurality of instruments 6 have differently shaped heads as described above, it is possible to determine the instrument 6 located in the image I among the plurality of instruments 6.
The instrument 6 is used at various angles, and the distance from the imaging unit 12 to the oral cavity of the patient is not constant. Therefore, the image recognizing unit 13 learns images of various angles and sizes in advance for the head portion of each instrument 6 so as to cope with changes in the angle and size.

  In the dental treatment unit having the above-described units, the control unit 11 selects one instrument 6 detected by the image recognition unit 13 and sets the selected one instrument 6 as a driving target. More specifically, the control unit 11 switches the operation source so that the power source related to one instrument 6 detected by the image recognition unit 13 operates, or water is supplied to the instrument 6. The valve 6 is opened and closed so that the instrument 6 is driven and controlled in accordance with the operation on the foot switch 7. Thereby, in this dental treatment unit, the instrument which the surgeon is holding can be detected more accurately, and the instrument at the patient's mouth can be accurately driven.

The image captured by the imaging unit 12 is preferably displayed on the display 8. This is because the surgeon can confirm whether the patient's mouth is correctly imaged.
The imaging unit 12 preferably has a zoom function. Thus, the surgeon can arbitrarily set which range of instruments is to be driven.

FIG. 3 is a diagram for explaining another example of a dental treatment unit according to the present invention.
The dental treatment unit of FIG. 3 has a microscope 20 for magnifying the inside of a patient's mouth, and an imaging unit 12 ′ is provided in the microscope 20, and the imaging unit 12 ′ has an eyepiece part of the microscope 20. The same image as that observed at 21 is obtained. As in the dental treatment unit of FIG. 1, in the dental treatment unit of FIG. 3, the instrument 6 recognized by the image recognition unit in the image picked up by the image pickup unit 12 ′ is set as a drive target.
By doing in this way, since only the instrument located in the place close to an affected part can be made into a drive object, it can prevent that an instrument is driven in other places and a patient etc. are injured. . Further, in this configuration, it is possible to prevent the instrument head portion from being hidden from the imaging unit 12 ′ by the operator.

  In the above example, the foot switch is a corded type, that is, a wired type, but may be a cordless type, that is, a wireless type. Further, the plurality of instruments are not limited to the wired type in the above example, and some or all of them may be wireless types.
