Portable medical operation headlight

Abstract

The invention discloses a portable medical operation headlight. The portable medical operation headlight comprises a head belt, an adjustment clamping ring, a fixing seat, a headlight device, a magnifying lens device and a power supply box, wherein a set of breathable holes are formed in the head belt, the adjustment clamping ring can adjust the tightness of the head belt, the fixing seat is fixedly arranged on the head belt, the bottom end of the fixing seat is bent upwards and extends to form a connecting seat, the headlight device comprises an LED headlight and a headlight supporting frame, one end of the headlight supporting frame is fixed to the connecting seat in a threaded mode, the other end of the headlight supporting frame is connected with the LED headlight in a rotary mode, the magnifying lens device comprises a binocular magnifying lens and an adjustment mechanism, the binocular magnifying lens is connected with the connecting seat through the adjustment mechanism and located right below the LED headlight, the power supply box is fixedly arranged on the head belt and electrically connected with the LED headlight through a wire, and the wire is embedded in the head belt. The portable medical operation headlight is simple in structure, portable, comfortable to wear and wide in use range, and a doctor can clearly observe the scene of the affected part through the portable medical operation headlight.

Description

technical field [0001] The invention relates to the field of medical optical instruments, in particular to a medical operation 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. In view of this, how to design a portable and flexible surgical headlight as an auxiliary light source has always attracted attention. [0003] Existing operation headlight mainly contains two kinds, and a kind of is the optical fiber operation headlight, and another kind is the LED...

AI Technical Summary

Problems solved by technology

[0005] 1. The illuminant is bulky, inconvenient to carry, low in photoelectric conversion efficiency, and high in power consumption;

[0006] 2. The life of the bulb is limited (about 500 hours), it needs to be replaced frequently, and the cost of use is high;

[0007] 3. The optical fiber is easy to break, resulting in a decrease in light efficiency

[0009] 1. The structure is complex, bulky, inconvenient to carry, oppressive to wear, and has poor air permeability. Users who wear it for a long time are prone to fatigue and even headaches, which are easy to distract and cause medical accidents;

[0010] 2. The power cord is exposed, easy to break, high failure rate, and limited range of use;

[0011] 3. The direction adjustment of the LED headlight is inconvenient and the adjustment accuracy is poor;

[0012] 4. The photoelectric conversion efficiency is low, the power of the light source is 3-5W, the power consumption is large, and the working time is short

[0013] In addition, when the above two surgical headlights are used, the affected area is directly observed with the naked eye. When it is necessary to observe the magnified scene of the details of the affected area, it is necessary to wear an additional surgical magnifying glass, such as wearing on glasses, which increases the wearing burden of the examiner. Great inconvenience to inspectors
