Differential evaluation and selection of surgical lights
I. Irradiation distance and depth
Usually the lamp manufacturers will give the light exposure distance and depth. Most of the light exposure distance is about 70--140 cm or 130 centimeters---, that is, the lamp in this distance of the best effect without shadow. In general, the larger the Lamp plate (single head lamp) or the number of heads, the better the irradiation depth, the more suitable for more depth of surgery. This is also the reason why some of the more complex surgeries often choose large surgical lights.
Illumination degree and color temperature
Illuminance and color temperature are in fact an approximation of the concept, are to describe the intensity of illumination. Usually we think that the ideal light is the ray and the sun approximate, and in the 4400--4600k around.
III. The number of joints and the stability and flexibility of the lamp arm
In order to be able to illuminate the focus of the various parts of the lesion, we hope that the more the joint, the better the angle of rotation of each joint, the greater the better. Generally good light should have 6 groups of joints, and each group of joint rotation angle is greater than 300 degrees, preferably 360 degrees. But the lights also can not be unlimited activities, do not want to touch the lamp on the run, so we can not be fixed for the light position. We usually define the degree of freedom of the lamp, that is, when the external force exerted on the lamp is less than 20 Newton, the lamp should not exercise, as long as the external force is greater than 20 Newton, the lamp side can be free to exercise.
