Description

  The present invention relates to a dental surgical light, and more specifically, the surgical light automatically follows the patient's oral cavity, and is automatically turned on to reduce the burden on the operator as much as possible. In addition, the dental treatment can be performed more hygienically so as not to touch the surgical light as much as possible.

  FIG. 2 is a diagram showing a schematic configuration of a dental treatment unit as an example of an apparatus to which a dental surgical light according to the present invention is applied. In the figure, 1 is a treatment chair, 2 is a work table, and 3 is an instrument. The holder, 4 is an instrument, 5 is a surgical light, and 6 is a surgical light arm. As is well known, in the dental treatment, the surgical light 5 is used to illuminate the inside of the patient's cavity. .

  The surgical light 5 is supported by the arm 6 and can be moved to any desired position. When illuminating the cavity opening during dental treatment, the surgical light 5 is held by the handle 7 to hold the surgical light 5 on the patient's face. The operating light or the like is pressed to turn on the surgical light 5 and when it is not in use, it is moved away from the patient and turned off.

  In order to move the operating light 5 manually with the handle 7 and to turn it off, generally, a switch provided in the vicinity of the operating light 5 is manually operated. Therefore, the handle and the switch are dirty. In particular, if the dirty handle and the switch are manually operated before the treatment, the operator's hand becomes dirty and the treatment is performed with the dirty hand, which is very unsanitary.

  Therefore, in medical treatment such as dental treatment, it is necessary to keep the part touched by the operator's hand as clean as possible from the viewpoint of hygiene. Generally, the handle part and the switch part are occasionally disinfected. It was equal. However, in practice, the disinfection work has to be performed frequently, which is not only troublesome, but also has a problem that it is not always completely sterilized.

  The present invention has been made in view of the circumstances as described above, without causing the shadow light to touch the hand, and automatically causing the shadow light to follow a desired position with respect to the patient's oral cavity position; and The lamp can be automatically turned on or off, thereby enabling the hygienic handling of the surgical light.

  The invention of claim 1 is a dental surgical light for illuminating the inside of a patient's oral cavity, and has a temperature sensor on the surface of the surgical light, and detects the temperature in the oral cavity of the patient by the temperature sensor. When the measured temperature is equal to or higher than a predetermined value, the operating light is turned on.

  The invention of claim 2 has a distance sensor on the surface of the surgical light, the distance sensor detects the distance to the oral cavity of the patient, and when the detected distance falls below a predetermined distance, It is characterized in that is lit.

  The invention of claim 3 is characterized in that a metal sensor is provided on the surface of the surgical light, and the surgical light is turned on when an instrument in the oral cavity is detected by the metal sensor. is there.

  The invention of claim 4 includes a temperature sensor for detecting the temperature in the oral cavity of the patient on the surface of the surgical light, and a metal sensor for detecting an instrument in the oral cavity of the patient, and the logic of both outputs of these sensors. It is characterized in that the surgical light is turned on by the product.

  The invention of claim 5 has a distance sensor for detecting the distance to the patient's oral cavity on the surface of the shadow lamp in the invention of claim 4, and when the shadow lamp approaches the patient to a predetermined distance, It is characterized by lighting the lamp.

  The present invention has been made in view of the circumstances as described above, without causing the shadow light to touch the hand, and automatically causing the shadow light to follow a desired position with respect to the patient's oral cavity position; and It can be turned on automatically or turned off so that it can be used in a sanitary manner.

  FIG. 1 is a schematic configuration diagram for explaining an embodiment of a surgical light according to the present invention. In the figure, 4 is an instrument, 5 is a surgical light, 6 is a surgical light arm, and 7 is no light. With the handle of the shadow lamp 5, conventionally, the shadow lamp 5 has the operator holding the handle 7 to move the shadow lamp to a desired location (in front of the patient's oral cavity) and turn on a switch (not shown). It was turned off and turned on and off.

  The present invention is such that manual movement, lighting and extinguishing are automatically performed as described above. Therefore, on the surface of the surgical light 5, at least one of the temperature sensor 11, the metal sensor 12, and the distance sensor is provided. As a result, the surgical light 5 automatically follows the movement of the patient's oral cavity, automatically turns on and off.

  The temperature sensor 11 detects that the temperature of the patient's face is higher than that of the other surrounding parts, and directs the surgical light 5 toward the higher temperature so that the surgical light 5 is turned on. The metal sensor 12 detects the presence of metal in the oral cavity, that is, detects that the surgeon is performing dental treatment using an instrument (handpiece), and lights the surgical light 5. . In this case, the lighting of the surgical lamp 5 by the temperature sensor 11 and the lighting of the surgical lamp 5 by the metal sensor 12 are performed independently (in parallel), and when the lighting is already performed by one sensor, the other sensor The lighting state does not change depending on. For example, even if the instrument is taken out from the oral cavity during dental treatment and the metal sensor 12 no longer detects the instrument, the surgical light 5 is not turned off.

  However, on the other hand, when the dental treatment is not performed, for example, when the patient first sits in the treatment chair and waits for the dental treatment to start, or during the dental treatment, the operator leaves the seat. In such a case, lighting the surgical light 5 is a wasteful use of electric energy, which is dazzling and uncomfortable for the patient. In order to avoid such a situation, when the temperature sensor 11 and the metal sensor 12 are both operated, that is, the face of the patient is detected by the temperature sensor 11, and the instrument is detected by the metal sensor 12. It is sufficient that the operating light is turned on when the logical product of the outputs of both sensors is established, and is not turned on when only one of them is turned on.

  Furthermore, if the surgical light 5 is too far away from the patient, the patient's oral cavity cannot be illuminated sufficiently. The distance sensor 13 is for that purpose, and the distance sensor (ultrasonic sensor, infrared sensor, etc.) 13 detects the distance to the patient's face until the distance reaches a predetermined distance. The surgical light 5 may be automatically brought close to the patient and turned on when a predetermined distance is reached. The distance sensor 13 may be turned on / off independently of the temperature sensor 11 and the metal sensor, or may be combined and turned on / off. You may make it do. For example, when no instrument is detected by the metal sensor 12, the surgical light 5 can be automatically moved away from the patient and simultaneously turned off.

  As described above, according to the present invention, a temperature sensor, a metal sensor, a distance sensor, and the like are provided on the front surface of the dental surgical light, and the surgical light is automatically set to a desired treatment position by these output signals. In addition, since the operating light is automatically turned on / off, the opportunity for the operator to touch the operating light is reduced, which not only reduces the operator's labor, Hands are kept clean and more hygienic dental treatment can be performed.

It is a figure for demonstrating the surgical light by this invention. It is a figure for demonstrating the example of the dental treatment unit provided with the surgical light to which this invention is applied.
