Description

Oral lighting device

The present invention relates to an oral illumination device, and more particularly to an illumination device for use in deep oral cavity.

The tonsils are lymphoid tissues on both sides of the oropharynx of the human body and are part of the body's immune system to combat the invasion of foreign germs. The most common medical problem associated with the tonsils is obstructive hypertrophy or infection. Since there are many glandular fossa on the surface of the tonsil gland, it is easy to hide food debris or pathogenic bacteria, so it is easy to cause infection. Clinically, antibiotics are usually used first, but if the tonsils have recurrent inflammation, they will be considered for further surgery. In addition, tonsil hypertrophy is often caused by increased immune activity. Hypertrophy itself is not a disease, but when the tonsils are obviously too large, blocking the respiratory tract, causing snoring or life problems in the patient's sleep process, and may even cause respiratory termination in severe cases. When the problem threatens the patient's life, the otolaryngologist usually recommends removal of the tonsils.

During the tonsillectomy procedure, the external illumination (eg, the surgeon wears a fiber-optic projection lamp) is used to illuminate the surgical field, but this also results in clinical limitations. For example, a fiber-optic projection lamp often has a poor swing angle of the surgeon's head, so that the light may be blocked and cannot completely follow the entrance throat region, forming a shadow line difference between the line of sight and the field of view. Furthermore, the fiber optic wire of external light is easy Fiber breakpoints are created for repeated use, in other words, these fiber optic wires have a useful life and are expensive. In addition, since the fiber-optic projection lamp is worn on the surgeon's head, the length of these external fiber-optic wires also affects the relative position of the surgical instrument, and also limits some activities of the operator.

It can be seen that the current illumination device for surgery is extremely inconvenient for the removal of the tonsils. On the one hand, the surgeon needs to focus on the process of the operation, on the other hand, it is also necessary to control the angle of the light source, and because the position of the light source is limited by the swinging manner of the head of the person wearing the light source, it is difficult to ensure the uniformity of the illumination of the light source, and thus it is serious. Affect the progress of the operation.

In view of this, there is an urgent need for an improved oral lighting in this field. The device is used to improve the problem of insufficient illumination and inconvenient use of the deep oral illumination device in current oral surgery.
