DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental mirror used for intraoral treatment, and more particularly to a vacuum-equipped dental mirror which is also used for removing cooling water and body fluid used during treatment. .

[0002]

2. Description of the Related Art When treating crowns and roots in the oral cavity, a practitioner who is a dentist holds a handpiece on which a polishing knife (berth) or the like is set and holds a dental mirror in the other hand. While carrying out necessary medical treatment while illuminating the treatment site via the dental mirror, the grinding of the enamel layer of the crown with the polishing blade suppresses the generation of excessive heat at the grinding point. For cleaning the grinding part,
During the grinding, the treatment is performed while spraying a large amount of cooling cleaning water. On the other hand, since the above-mentioned treatment is performed in a state in which the patient is substantially turned upright, the patient is forced to have difficulty breathing when the body fluid and saliva from the affected part during the operation and the waste fluid such as the cooling water are filled in the oral cavity. As a result, a situation in which the waste liquid is swallowed is often seen. In order to prevent such a situation from occurring, the assisting surgeon intermittently sucks and discharges the waste liquid.

[0003] Moreover, since the removal of waste liquid through the vacuum pipe during the above-mentioned treatment is performed intermittently and due to the practitioner's treatment, the patient's swallowing of the waste liquid is performed more or less, so that the patient suffers from so-called pain. Will be forced. In the case of removing the waste liquid by the treatment assistant by making full use of the vacuum pipe, the treatment assistant performs during the short treatment stop time through the following procedure. That is, a. Check the pool of waste liquid in the oral cavity and insert the suction port of the vacuum pipe into the oral cavity. b. Check the undulation of the mucous membrane around the pool corresponding to the unevenness of the waste pool, and prevent the suction port from being blocked by directly sucking up the mucous membrane. c. Since the waste liquid is not always collected at one place, suction is performed at a plurality of places based on an appropriate judgment and feeling of the treatment assistant. The above operation has the following problems. That is, 1) Since the waste liquid is removed intermittently in the confirmation of the waste liquid collecting point in the item a, the waste liquid is not always formed in the vicinity of the affected part during the treatment, and the situation is not substantially understood by the practitioner. Although it can be confirmed, peeking from the side direction is not enough for the assistant, and the work is done with the feeling of the assistant in the end. Will not be relieved. 2) It is difficult to effectively remove only the waste liquid without blocking the suction port with the mucous membrane in correspondence with the undulation of the mucous membrane at the waste liquid pooling point in the item b. Depending on the shape of the suction port of the conventional vacuum pipe, It is difficult to insert the vacuum pipe and perform suction only once, and it is a situation where the suction port is changed in direction after the suction port is closed, resulting in incomplete suction.

[0004] If the operator cannot remove the waste fluid satisfactorily, the operator operates the operating table to take the patient in the supine position to the sitting position and perform the required gargling by the patient. After the end of the gargle, the patient is returned to the supine position again and the interrupted procedure is continued. But
In this case, the position of the affected part of the patient slightly changes, and the practitioner will continue the treatment again while following the image of the affected part before gargle, in order to respond to the subtle position change of the affected part, and the inefficiency of treatment And the cause of the decrease in treatment accuracy. In addition, if the above-mentioned waste liquid cannot be removed, the patient is forced to take the physiological action of “swallowing the waste liquid”, which poses a problem in hygiene and causes a great deal of pain to the patient who is in the open state with his back turned. It is.
