The monitor 70 outputs an oral image photographed by an oral camera and / or a projection image photographed by X-ray imaging.

The medical device 10 according to the present invention will be described in detail with reference to FIG. 2 to FIG. FIG. 2 is a view schematically showing a medical device having a light source unit and an X-ray generator according to the present invention, FIG. 3 is a view schematically showing a main body of the medical device shown in FIG. 2, Sectional view schematically showing a transverse section of the periphery of the medical device shown in Fig.

2 to 4, a medical device 10 according to the present invention includes a main body 11, a light source 12 for irradiating light into the oral cavity, an X-ray generator for irradiating the X- A peripheral portion 20 provided at an edge of the main body portion 11 and a supporting portion 15 for supporting the main body portion 11.

The light source unit 12 is composed of a plurality of light sources 12-1, 12-2, 12-3, ... arranged radially around the central portion of the main body 11 as shown in Fig. In this case, it is preferable that a light-emitting diode (LED) capable of realizing high illumination with low power consumption is used as a light source. Specifically, an LED substrate (not shown) having a plurality of LEDs arranged in a circular shape is installed inside the body portion 11, and a heat sink (not shown) for efficiently emitting heat generated from the LED is provided on the LED substrate .

As shown in Fig. 3, the x-ray generator 13 is disposed at the center of the main body 11 and irradiates x-rays toward the affected part of the patient. More specifically, the X-ray generator 13 is an element for generating an X-ray by colliding an electron having a high kinetic energy with a metal target. The X-ray generator 13 is a unit for generating a nano structure of a carbon nanotube (CNT) And a field emission system using a field emission emitter of a material.

5 is a cross-sectional view showing an X-ray tube (XRT) of the field emission type applicable to the X-ray generator 13 of the present invention. The X-ray tube XRT defines a vacuum space S sealed therein, As shown in FIG. Of course, the shape of the X-ray tube XRT is not limited to the cylindrical shape.

The X-ray tube XRT includes a cathode 82 formed on the upper surface of the nanotube emitter 84 to emit electrons and a cathode 82 disposed to face the cathode 82 so as to face each other, And a separator 88 for separating the anode 86 and the cathode 82 from each other.

The separator 88 has a tubular shape, and the cathode 82 and the anode 86 are disposed on both sides with the separator 88 interposed therebetween. The separator 88 may be an insulating material, for example, a ceramic, but not limited thereto.

Meanwhile, although not specifically shown, the X-ray tube XRT may further include a gate electrode disposed between the cathode 82 and the anode 86. The gate electrode has a plurality of gate holes of a constant pitch located in the vacuum space S, and the electrons emitted from the cathode 82 pass through the gate hole to the anode 86.

2, the lower surface (that is, the incident surface) of the anode 86 on which electrons are incident is inclined, and has a reflection characteristic, and the electron incident angle &thetas; (XRT) in which an X-ray is emitted in the direction of an angle symmetrical to the X-ray tube.

On the other hand, as the X-ray tube (XRT) of the embodiment of the present invention, a transmissive X-ray tube in which X-rays are emitted in a direction substantially the same as the direction of electron incidence can be used.

For reference, carbon nanotubes (CNTs) among various nanomaterials are excellent in the field emission characteristics according to their high chemical stability, thermal conductivity, mechanical strength, and high aspect ratio, and can be miniaturized and lightweight.

As a result, even when the X-ray generator 13 needs to be broken or repaired, the present invention can be used semi-permanently by simply replacing the field emission X-ray tube XRT.

As shown in Fig. 2, the peripheral portion 20 is a tapered cone-shaped cylindrical member having both ends open and widening the opening area along the direction in which the x-rays and / or light are radiated, And surrounds the light irradiated from the light source unit 12 and the X-rays irradiated from the X-ray generating unit 13.

The peripheral portion 20 has a reflective layer 21 of a surface-treated aluminum material. The light reflected from the light source unit 13 is reflected through the reflective layer 21 so that the light can be radiated in various directions, while the back scattering of the illumination is reduced, can do.

A shielding layer 22 made of a lead material is further formed on the outer side of the reflection layer 21. By shielding the radiation emitted from the x-ray generator 13 through this shielding layer 22, the amount of radiation exposure can be minimized.

As shown in Fig. 1, the supporting portion 15 is a constituent element for supporting the main body portion 11. The supporting portion 15 includes a first arm 16 installed on one side of the unit chair 1 and standing vertically, A second arm 17 rotatably connected to the first arm 16 so as to be rotatable with respect to the first arm 16 and a third arm 17 rotatably connected to the second arm 17 in a hinged or articulated manner 18. At the distal end of the third arm 18, the main body portion 11 is rotatably connected in a hinged or articulated manner.

The main body portion 11 can be moved in the direction away from or close to the patient, or vertically and laterally about the patient through the support portion 15. Thus, the physician can easily adjust the position of the main body part 11 to face the oral cavity or the affected part of the patient.

Now, a method of treating a patient using the unit chair 1 according to the present invention will be described in detail.

When the patient is seated in the chair 30, the doctor adjusts the height of the chair 35 using the foot controller 35, and then rotates the backrest 32 to turn the patient into a lying state .

The doctor moves the position of the main body part 11 of the medical device 10 according to the present invention toward the mouth of the patient and then the switch 14 To switch the medical device 10 according to the present invention to a light mode so that light is irradiated inside the patient's mouth. At this time, a dimming circuit for controlling the output of the light source is additionally provided in the main body 11, and the intensity of the illuminance (for example, the low illuminance state, the medium illuminance state, and the high illuminance state) can be adjusted through the switch operation.

The doctor can visually confirm the position of the affected part in the oral cavity through the illumination mode of the medical device 10 according to the present invention. Once the location of the lesion in the mouth is confirmed, x-ray imaging is performed to acquire a projection image in order to accurately read the tooth condition and / or the gingival state of the lesion in place without the patient's position.

In order to perform X-ray imaging, the doctor moves the position of the main body 11 of the medical device 10 according to the present invention from the outside of the patient's mouth toward the affected part, (10) into the X-ray mode (X-ray mode) and irradiates the X-ray toward the affected part of the patient. At this time, an X-ray detecting unit, for example, an intraoral sensor, for detecting the irradiated X-ray is located adjacent to the affected part in the oral cavity.

The X-ray detecting unit detects the X-rays emitted from the X-ray generating unit 13 and generates an electric signal for each position proportional to the incident amount of the detected X-rays. Then, the electrical signal and the positional information are read and processed by an image processing algorithm to generate a two-dimensional projection image of the teeth and / or the gums of the affected part and output through the monitor 70.

Since the doctor can more accurately confirm the position of the affected part of the patient through the unit chair 1 according to the present invention and can perform X-ray imaging for the affected part successively, the doctor can more quickly read out the tooth condition and / can do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. That is, those skilled in the art will appreciate that various modifications, changes, and / or substitutions are possible without departing from the spirit of the invention.
