Medical head lamp

Abstract

The invention discloses a medical head lamp. The medical head lamp comprises a head wearing mechanism, and double lamp caps mounted on the head wearing mechanism through a rotating mechanism; the headwearing mechanism comprises a width-adjustable head copying structural body, and a first clamping part and a second clamping part which are respectively mounted at the two ends of the head copying structural body; the double lamp caps comprises a first lamp cap and a second lamp cap which are fixedly connected through a connecting plate; and the included angle of emitted light rays of the first lamp cap and the second lamp cap is a preset angle. The two lamp caps with a certain included angle are adopted; the whole double lamp caps can be rotated by multiple gears to realize the functions offocal distance adjustment and light condensation; and users can adjust the double lamp caps to a proper angle according to demands, so that the use experiences of the users are greatly improved. In addition, the width of the head wearing mechanism is adjustable; and through the two independent clamping parts, the medical head lamp is suitable for wearers with different head circumference sizes, sothat the unified wearing comfort can be guaranteed, and the operation is simple and fast.

Description

technical field [0001] The invention relates to the field of medical optical instruments, in particular to a medical headlight. Background technique [0002] Good lighting conditions are essential for examination and surgery. At present, the lighting sources used in hospitals are all shadowless lamps. Shadowless lamps can illuminate the surgical site without producing obvious umbra, but it is difficult to clearly illuminate the deep narrow parts of the patient. Even if some parts can be illuminated, they cannot follow the doctor. The angle of view changes steadily, requiring the patient to change the position at any time, which brings inconvenience to the diagnosis and treatment work. Therefore, hospitals generally use medical headlights that can be worn on the head. Medical headlights have been widely used in medical surgery lighting and surgical supplementary lighting. However, the medical headlights commonly used at present have the following defects: [0003] 1. The s...

AI Technical Summary

Problems solved by technology

[0003] 1. The size of the headband cannot be adjusted, and each wearer has a different head size, so uniform wearing comfort cannot be guaranteed

[0004] 2. Only a single lamp head is used, and the focal length is fixed. In order to allow the light to irradiate the designated position, the wearer can only adjust the angle of the light by turning the head or neck, which is prone to cervical fatigue and affects vision health
