Let there be light (in the OR).
Even after the invention of the electric light, and the subsequent improvements and advancements in lighting technology, providing efficient and effective illumination in the Operating Room has remained a challenge. While the electrically lighted OR did revolutionize surgery, it is the optimal visibililty of the patient in general, and the surgical site specifically, that directly effects the time, technique, and outcome of a given procedure.
Today surgeons have a wide variety of choices when it comes to surgical lighting. Major ceiling mounted surgical lighting systems can deliver illumination across the entire sterile field, and also be adjusted to concentrate light on the surgical site itself. Headlight systems allow light to be focused directly where the surgeon needs it most. Technological advancements over the past few years to both styles of lighting systems now enables them to provide color correct light that improves tissue differentiation with little or no radiant heat from the bulb. This can make procedures easier, faster, and far more comfortable for both the surgeon and the patient.
The surgical light and light source market is quite broad now, with dozens of manufacturers and marketers competing to meet the ever growing needs of surgeons. As a result, surgical lighting technology continues to trek ahead. Recent years have seen the emergence of deep cavity illumination devices, ever more flexible lighting systems, and even headlight systems that unshackle the surgeon from the traditional fiber optic light cable. Here is a look at some of the latest developments in lighting technology available to the modern OR.
