Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dental treatment unit in which a scope for observing an oral cavity is housed in the same site as a treatment instrument and a display for the monitor is arranged as a liquid crystal display in the vicinity of the periphery of the treatment unit.

[0002]

[Prior art]

 For dental treatment (including diagnosis, interview, and medical treatment), it may be necessary to closely observe the inside of the oral cavity. In order to respond to such demands, conventionally, a cabinet body with casters accommodating various operation parts and image storage circuits has been prepared, and a CCD camera for capturing the inside of the oral cavity in the main body of the cabinet and an image thereof are displayed. An intraoral observation device that is connected to a monitor display such as a CRT has been proposed (Jikkou 3-32 330). In actual use of the intraoral observation device, the device is drawn to the vicinity of the dental treatment unit and used at each treatment.

[0003]

[Problems to be solved by the device]

 However, in the vicinity of the dental treatment unit, there are doctors and assistants (assistants), various other treatment devices and equipment, and the movable table of the unit itself. The current situation is that there is not enough room. It is quite difficult to draw the above-mentioned intraoral observation device to such a narrow space every time it is used. At times, it may be necessary to dismiss other devices and equipment and draw them. In addition, the power cord attached to the intraoral observation device and the cord part for transmitting the image from the intraoral observation scope may interfere with the treatment, and doctors may stumble upon these codes. There was also such a danger.

In particular, during treatment, when an image chart is left by alternately using the treatment device and the scope for intraoral observation, an instrument (cutting tool) for treatment and a scope for photographing are used. Since it is used repeatedly, it is very troublesome to pull out the instrument from the treatment table or pull out the scope by pulling in the intraoral observation device each time to perform different operations (work) each time. It was Also, when there are multiple treatment units and one intraoral observation device is shared, it is necessary to move the intraoral observation device for another patient during treatment of one patient. At that time, however, it was annoying that I could not use it immediately when I wanted to use it, as it interfered with other treatments for a certain patient.

The present invention has been made in view of the above conventional problems. The adoption of the movable cabinet body is stopped, and the scope for oral cavity observation is stored in the same position as the therapeutic instrument. In addition, the monitor display is arranged as a liquid crystal display near the periphery of the treatment unit to provide a dental treatment unit with improved usability.

[0006]

[Means for Solving the Problems]

 The feature of the present invention is basically a dental treatment unit equipped with a scope for observing an oral cavity in a holding portion for accommodating an instrument for dental treatment. If necessary, a liquid crystal display for displaying the image captured by the intraoral observation scope or the image captured by another image input device or image input terminal may be installed near the periphery of the treatment unit. , Presence or absence of a storage medium driver and an image storage circuit for storing the image captured by the intraoral observation scope in the storage medium, and an intraoral observation scope attached to the holding section for storing the instrument Sensor, the other image input device, or the image input terminal to switch the image input switch to display on the liquid crystal display. Le is obtained by attaching a display control circuit for displaying the background color as a film viewer.

[0007]

With this configuration, in the present invention, the scope for oral cavity observation can be extended from the holding portion of the instrument and used like an ordinary instrument, and the image at that time is displayed on the treatment unit. It is displayed on the LCD display installed near the periphery. Also, the image from the mouth observation scope is stored in the storage medium as an image chart by the memory medium driver and the image memory circuit, and the image is displayed on the liquid crystal display in synchronization with the drawer of the mouth observation scope by the sensor. The image from the other image input device or image input terminal can be displayed as a background image or commercial image with the image input selector switch along with voice or music, and the liquid crystal display can be used as the background color. It can be used as an X-ray film viewer or the like.
