By the time the shadowless lamp was repaired, the operation on the No. 1 operating table had been completed, and the doctor and patient had already left.

The nurse handed Director Zhang and Warlene the gauze soaked with alcohol to wipe their hands, and said to Director Zhang: "Director Zhang, our head nurse said that we will come by ourselves to adjust the position of the shadowless lamp, you have worked hard." ”

"Okay, then I'll be lazy. Director Zhang carefully wiped the dirt off his hands, "Anyway, only the person who operated on the position of the shadowless lamp during the operation knows best, we just want to adjust the position, and we also want your doctors and nurses to be present." ”

Different surgeries have different requirements for the position of the shadowless lamp, and this can only be seen on the scene.

Following Director Zhang out of the operating room, Wallen let out a sigh of relief.

Director Zhang smiled: "What's the matter, are you uncomfortable in the operating room?"

"It's very nervous," Warleen admitted, "and it's a little uncomfortable." ”

"The little girl is good, the first time I saw a craniotomy, I dared to come forward. Director Zhang teased, "I heard that the old fox sent you in, and I scolded the old fox in my heart, worried that your little girl would cry in fright, it seems that the old fox was scolded by me in vain." ”

You cursed in your heart, but he didn't hear it. "Warlene is funny.

"Director Zhang, shouldn't the doctor be very attentive during the operation, why are they talking about other things?"

"I think you've watched too many movies," Director Zhang shook his head with a smile, "The operation takes a few hours, like the surgery in their neurology department, it is common for an operation to take more than ten hours, if you don't talk about something else, how can people stand it." ”

"But, if you talk about anything else, will you be distracted during the operation?"

"It's not a distraction, it's a refreshment, you think that surgery is a life-saving and sacrosanct thing, but for doctors, they do surgery just like we repair machines, they are used to it, it's not a big deal, but even if it's a hand-to-hand thing, focusing on one thing for a long time, causing brain fatigue, but easy to make mistakes. ”

"Oh, that's right. Warleen was relieved.

She thought of another question: "There are so many light bulbs in the shadowless lamp, don't they produce a lot of heat, how can the doctor stand it after standing under the shadowless lamp for so long?"

Director Zhang nodded: "Of course it will be very hot, so the top of the shadowless lamp is open, and there is a fan, just to make the heat generated by the bulb dissipate as soon as possible. ”

"Is there a light bulb that emits light without producing heat?" asked Wallen, who thought it was impossible.

Director Zhang said: "Yes, cold light source bulbs, if the operating room is replaced with cold light source shadowless lamps, you can avoid the problem of heat dissipation of shadowless lamps, the probability of damage to the bulbs of shadowless lamps will be reduced, and the life span will be greatly extended." ”

If the shadowless lamp does not emit excessive heat, it can make the surgeon uncomfortable and dry out the tissues in the surgical area.

The cold light source bulb uses the light source principle of LED, basically no thermal radiation under normal work, belongs to semiconductor lighting, DC drive, no strobe, no infrared and ultraviolet components, no radiation pollution, high color rendering, strong luminous directionality, good dimming performance, and color temperature changes will not produce visual errors.

The cold light source can not only provide a comfortable light space, but also well meet the physiological health needs of people, is a healthy light source to protect vision and environmental protection, and the cold light source shadowless light is of great benefit to the doctor who does the operation and the patient who undergoes the operation.

Director Zhang only knew that there was already a cold light source shadowless lamp, and also suggested that this kind of equipment be introduced in the operating room, but whether the specific hospital would agree to it was not something he could control, after all, it involved the issue of funds.
