Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a head- or face-mounted medical lighting device for illuminating a treatment site of a patient in the medical fields such as dentistry, otolaryngology, ophthalmology, and oral surgery.

[0002]

[Prior art]

 Conventionally, as a device for illuminating a medical treatment site of a patient, 1) an articulated surgical light type in which a surgical light is attached to the tip of a flexible arm, 2) a flexible arm is used instead of the flexible arm to guide light inside the arm. A flexible arm type with fibers arranged, 3) A frame type in which one light source is attached to the frame to illuminate from the upper part of the operator's frame is used.

[0003]

[Problems to be solved by the device]

 However, in the conventional articulated surgical light type, an operator or an assistant must manually operate when changing the illumination site and illumination direction. Therefore, the operation becomes complicated and contact-type infection may occur. In addition, although the light source of the surgical light is used, the light source is far from the patient, so the generation of shadow cannot be avoided.

In the conventional flexible arm type, since the area of the light source is one point, a shadow is generated, and therefore it is necessary to adjust the illumination angle frequently. In addition, the illumination light is often directly exposed to the patient's eyes, resulting in glare.

In the conventional forehead type, since there is only one light source, a shadow is likely to be generated by the operator's hand or instrument. In addition, since the light source is placed on the front of the operator's head, the visual field is easily obstructed and the operation is complicated due to the feeling of weight. In addition, since a light bulb is incorporated in the light source, the patient may feel heat from the light source when approaching the patient, which may cause discomfort.

An object of the present invention is to provide a head- or face-mounted medical lighting device that has good operability, is less likely to cause shadows, and is easy to observe.

A head comprising: a pair of left and right lighting means having an illumination angle set as described above; a light guide for transmitting light to the lighting means; and a light source for supplying light to the light guide. Part or face-mounted medical lighting device. According to the present invention, since the illumination light is emitted from the pair of left and right illumination means arranged outside the eyes of the user, the illumination is performed from the left and right with the visual field as the center. Therefore, since the direction of the field of view and the direction of the illumination are almost the same, it is easy to adjust the illumination angle. Moreover, since the illumination is performed from two illumination directions, shadows are less likely to occur. Furthermore, since the light guide is used to guide the light source, the light source can be installed far away, so that the overall size and weight can be reduced, and the heat generated by the light source is not affected.

It is characterized in that a condensing lens for condensing the illumination light is provided on the emission side of the illuminating means. According to the present invention, since the light guides that branch from the single light source to the left and right illumination means are used, there is no need to install separate light sources on the left and right, and the configuration can be simplified. Further, since the condenser lens for condensing the illumination light is provided on the emission side of the illumination means, it is possible to efficiently illuminate a narrow area such as the oral cavity. Further, it is possible to reduce the direct light which makes the patient feel dazzling.

The present invention is also characterized in that the mounting member is a goggle type that forms a sealed space in front of both eyes of a user and has a window made of a light transmissive material. According to the present invention, it is possible to prevent the shavings, saliva, and drug solutions that scatter during treatment from entering the eyes of the operator, and realize safe and hygienic medical treatment. Also, the operator can wear this device while wearing his or her own glasses.

Further, the present invention is characterized in that the mounting member is a spectacle type having a pair of lenses arranged in front of both eyes of a user. According to the present invention, it is possible to prevent the shavings, saliva, and liquid medicine that are scattered during treatment from directly entering the eyes of the operator, and it is possible to realize safe and hygienic medical treatment. It is also possible to use the surgeon's glasses as they are.

Further, the present invention is characterized in that the mounting member is a frame type having a frame that is mounted so as to tighten around the head of the user. According to the present invention, the device can be securely mounted with a simple structure.
