Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patient's body position when a doctor or dentist explains a situation regarding a body part which cannot be viewed directly by a single reflecting mirror by the patient regardless of the body position of the patient. Regardless of this, the present invention relates to informed consent technology aiming to realize effective visual support.

[0002]

2. Description of the Related Art Generally, when explaining a situation to a patient at a medical site where a patient cannot see directly with one reflector, two reflectors are used or input by a CCD camera or the like is used. The explanation was given using the device, liquid crystal, and CRT monitor.

[0003]

However, as described above, in the situation where the patient himself / herself is performing the treatment in the horizontal medical treatment (medical treatment while the patient is lying on his / her back on the examination table) in the medical field, the patient himself / herself When explaining the actual symptoms of the anterior lingual surface and the occlusal surface of the molars that cannot be seen directly with the holding hand mirror using the two reflecting mirrors, the hand mirror and the dental mirror, which the patient holds, the doctor himself There is no way to check if the target area is correctly projected on the hand mirror held by the patient from the patient's point of view using the dental mirror, and it is very skillful to perform such actions relying on experience and feeling. Needed. Not only that, when projecting the patient's front teeth or face onto the LCD screen like a reflector, a CCD camera is installed around the LCD screen, so distorted images from the left and right sides or the vertical direction can be displayed. It will be projected. In addition, input devices such as CCD cameras, liquid crystal, CRT
Similarly, when explaining using a monitor, etc., the image displayed by the CCD camera can be confirmed only on the LCD, CRT monitor, etc., so it is necessary to position the monitor above the patient's head in horizontal medical treatment. Occurs. Even if a small LCD monitor is held by the patient like a hand mirror, a separate monitor is required to check the position of the CCD camera held by the doctor. Moreover, the doctor had to move his or her line of sight from the inside of the mouth toward the monitor, and it required skill to work without directly looking at the actual condition. in addition,
In the oral cavity, it was often found that the surfaces of mirrors and camera lenses were fogged by exhalation and cooling water of cutting instruments.

In view of the above situation, the present invention allows a doctor to look directly at a medical condition in which horizontal medical treatment is performed, and when explaining the present disease in a site such as the oral cavity that cannot be viewed directly. It is to provide a patient with an image that is almost the same as the actual situation without shifting the line of sight from the actual situation to the patient, and to provide a dental mirror with a CCD camera that prevents the surface of the mirror and camera lens from fogging.

SUMMARY OF THE INVENTION According to the present invention, a light entrance portion is located at the mirror surface center of a dental mirror or at the rear surface of the mirror portion where light is transmitted by removing a reflecting material at an arbitrary position. By installing a CCD camera in the and transmitting the image information of the CCD camera to a hand mirror-shaped monitor by wire or wirelessly, it is possible to perform horizontal medical treatment (to treat a patient while lying on his / her back on the examination table). Even if it is in a site such as the oral cavity that cannot be viewed directly under the condition where the treatment is performed, the doctor almost sees the target site with the dental mirror held by itself without shifting the line of sight from the oral cavity. The same field of view can be provided to the patient, and at the same time, any image can be provided at any time by accumulating the image information in the server. A micromotor equipped with a gear to cooperate with a gear installed to rotate the CCD camera around the CCD camera rotatably mounted at the center of the back of this dental mirror, and its battery. The drive micromotor has a mechanism to control the rotation angle of the CCD camera by the control device according to the signal of the gyro sensor in which the inclination of the dental mirror with respect to the horizontal plane (floor surface) is set in the holding part of the dental mirror. The subject can be photographed while maintaining a preset constant angle regardless of the holding angle and the insertion angle in the oral cavity. It is possible to easily determine which part of the image is displayed on the liquid crystal screen. At this time, of course
It is also effective for treatment of invisible areas such as root canal treatment. Furthermore, since the small hand mirror-shaped monitor can be held in a position where the patient can easily see it, not only can the image be viewed in the posture of horizontal medical treatment, but the center of the LCD screen of the hand mirror-shaped monitor can be viewed. A hand mirror-shaped monitor equipped with a CCD camera on the back of a liquid crystal panel with the liquid crystal removed from the center of the LCD screen so that light can be transmitted through the LCD screen. Since the front teeth and the face can be photographed, the image can be used like a general mirror without distortion from the vertical, horizontal, and diagonal directions. With a hand mirror-shaped monitor equipped with an image conversion processing device that can vertically and horizontally project the input information from this central CCD camera, the face is not visually reflected on the liquid crystal screen by a third party but by a third person. It is possible to reproduce the same screen as the one you see. In addition, the dental mirror unit can be used as a light source by reflecting an existing surgical light installed in the dental examination table to illuminate a target site. The system that inserts the CCD camera directly into the oral cavity by mounting it on the dental mirror is such that if the optical fiber light entrance part is located at the part where the reflecting material on the back of the dental mirror is removed, the light entrance will be at the other end. It is also possible to replace it with a dental mirror with a CCD camera equipped with a CCD camera for inputting the field of view obtained from the section.
In this system, a CCD camera is installed in front of the hand-mirror-shaped monitor and always provides an image to the hand-mirror-shaped monitor through an optical fiber.When the optical fiber is removed, the CCD camera directly projects the front surface of the monitor, so that a general reflection is possible. It can be used like a mirror hand mirror. In this case, the light source may be a light source such as a surgical mirror of a dental clinic by reflecting light from the dental mirror portion, or a halogen lamp light source may be used to illuminate the visual field from the tapered fiber portion of the optical fiber. can do. However, when the above-mentioned dental mirror with a CCD camera is used, it is often found that the surface of the camera lens is fogged by the exhaled air or the cooling water of the cutting instrument. In order to solve this problem, a ventilation pipe with the injection port facing the CCD camera and the optical fiber light input part is installed coaxially or axially with the dental mirror holding part, and a dental mirror mirror surface using a compressor, By injecting air into the CCD camera and the optical fiber entrance part, it is possible to secure the field of view by scattering cloudiness, saliva, cooling water, and the like. At this time, if an uncomfortable feeling due to drying due to the air blown into the oral cavity occurs, a suction port connected to the vacuum device is provided at a position opposite to the jet port to suck the jetted air. It is possible to prevent the inside from being dried unnecessarily.
