Technical Field

The invention belongs to medical equipment, in particular to an illuminating device for examination and treatment in otolaryngological department.

Background

The otolaryngological department is the first subject to examine and treat diseases by using headlights, because the anatomical parts of the otolaryngological department are deep, and it is difficult to examine and treat diseases without special lighting equipment. The types and specifications of headlamps are many, from conventional halogen light bulb headlamps and frontal mirror reflector lamps to modern various light guide fibers and LED headlamps, such as the chinese patent application: CN201020202925, CN201520614595 and CN 201610766935. Some headlamps are also provided with a magnifying glass and a camera, as in the chinese patent application: CN201420611558, CN201420588699 and CN 201820850338. These headlamps are generally adequate for a variety of inspection and surgical applications, but still suffer from a number of deficiencies and improvements. Because of special requirements for deep illumination in otorhinolaryngology, for example, narrow and deep parts such as tympanic membrane, nasal cavity or throat of external auditory canal, the optical axis of illumination of the headlamp should be consistent with the visual axis of eyes, and the closer to the visual axis, the deeper the illumination can be seen clearly. When a narrow and deep part is examined, only a single-eye visual angle is often used, and the stereoscopic impression is lacked and the part is not clear. The otolaryngology examination can be carried out by using an endoscope or a stereomicroscope, but the endoscope system and the stereomicroscope have complicated structures and large volumes, and are not suitable for routine outpatient examination and emergency consultation. The main disadvantage of many existing headlamps is that they are relatively bulky and heavy, for example, in chinese patent applications: CN201720388468 and CN201721357561, the number of imported headlamps is more than 300 g, and the weight of the domestic novel headlamp can be reduced to 145 g. Other drawbacks are insufficient brightness of the lamp, insufficient operation time, inconvenience in use, inflexibility in operation, etc. The ideal head lamp is light, bright enough, adjustable in brightness, adjustable in spot size, and capable of being placed in the position slightly above the middle of pupils of two eyes, and if a magnifier can be used, the effect is better. To solve these problems of clinical techniques, the present invention has been devised as follows.
