Description

Oral illuminating lamp with removable illuminating head

The model relates to the structure of an illuminating device, in particular to an oral illuminator with a removable illuminating head.

When the dentist observes the condition of the teeth or gums in the patient’s mouth in clinical use, the oral mirror is used to open the tongue or cheek, and then use the mirror at the end of the oral mirror to observe the image of the teeth reflected in the mirror to determine the condition of the teeth or gums . When it is necessary to use a light source to penetrate the teeth, and to further observe the light transmission condition when the light source enters the teeth to determine the tooth decay or other pathological conditions, a hand-held illuminator is used to penetrate deep into the oral cavity. The teeth are illuminated in depth.

The aforementioned conventional hand-held illuminator used in the oral cavity is provided with a power source inside the grip, and the power is supplied to the luminous hair at the front end of the grip to emit light to illuminate the teeth or the interior of the oral cavity. However, in order to avoid cross-infection between different patients, the instruments used by dentists usually need to be disinfected after each use to avoid cross-infection between patients. At this time, even if the light-emitting head is of a high-temperature sterilizable or disposable structure, because the handle is limited by the internal lighting circuit, power supply and other structures that are not resistant to high temperatures, it is impossible to sterilize the handle at high temperature, which will cause the handle to be reused Because the front part of the grip is contaminated with patient body fluids, there is a problem of cross infection between patients.

Since the existing hand-held illuminators used in the oral cavity cannot sterilize the handle, the handle may cause cross-infection of patients when the handle is reused. For this reason, the present invention is equipped with a detachable light source device in the handle, and a detachable irradiation head that can guide the light source device to emit light is arranged at the front end of the handle, so that the irradiation head can be detached, replaced and sterilized, and the handle can be separated The effect of high temperature disinfection.

In order to achieve the above creative purpose, the present invention provides an oral illuminator with a removable illuminating head, including:
