CHROMOPHARE® Surgical lights

OUR TRADITION IS INNOVATION

The goal of company founder Theodor Berchtold was to manufacture premium, state of the art products for the operating room. That was back in 1922. And his endeavor bore fruit: The world's first heart transplantation was performed under a CHROMOPHARE light. In 2001 a surgical light from worldwide market leader BERCHTOLD contributed to the success of the very first transatlantic operation.

Throughout the years BERCHTOLD has consistently been a driver of cutting edge technology. Some examples are:

?First polygon reflector

?First centrally integrated camera

?First ambient light (EndoLite)

?First automatic light field guidance system

Technologies may change, but BERCHTOLD's principles have remained the same. This is why BERCHTOLD's name today stands for high-quality OR technologies tailored to the needs of the OR staff. Whether it's about surgical lights, operating tables or multimedia information and documentation systems - in the operating room only the very best solutions survive:

The world's first centrally integrated OR camera was introduced in 1958 - in a CHROMOPHARE of course
The world's first heart transplantation was performed in a five hour operation on December 3, 1967 in Cape Town, South Africa by surgeon Christian N. Barnard under the illumination of CHROMOPHARE surgical lights.
The latest generation of high-tech reflector technology
In tune with the times: live transmission from the operating room - using CHROMOPHARE for light, ChromoVision for imaging and ORICS C 11 for information transfer.

HIGH LIGHT INTENSITIES FROM STATE-OF-THE-ART BRITeTM - TECHNOLOGY
	Surgeons working in the operating room must be able to recognize contours, colours and movement with absolute precision. To permit maximum visual acuity it is essential that the lighting conditions be accurately adaptable to varying conditions in the operating room. While small surgical fields require small light fields, deep-cavity operations with large surgical fields demand large light fields with high light intensities. However, since light intensity decreases with growing light field size, conventional halogen lights are only capable of supplying high intensities over relatively small light fields. In situations where the target tissue is difficult to reach and can no longer be directly illuminated, the demands placed on the surgical lighting become even greater. In these cases the usable light intensity of conventional halogen lights drops to levels that are barely higher than the ambient light intensity. BERCHTOLD is the first company worldwide to provide surgical lighting enhanced by BRITe technology. Featured in all 150 W CHROMOPHARE D series surgical lights, BERCHTOLD Reflective Illumination Technology (BRITe) is a novel technology which reflects undesirable infrared radiation back onto the filament. Infrared energy is reflected back to the filament, increasing the amount of visible light, ensuring that only cool light rays in the visible range reach the surgical field. With this technology, CHROMOPHARE lights are able to deliver up to 50% higher light intensities than previous models with no increase in energy consumption and no additional heat. BRITe is a quantum leap in modern surgical lighting which becomes especially visible with large, deep surgical fields. This is where the new technology shows its real potential, providing CHROMOPHARE surgical lights with light intensities reaching up to 160klx and light field diameters of up to 30 cm.

NATURAL COLOUR PERCEPTION

Colour perception is determined by the colour temperature of light entering the eye. For example, daylight has a colour temperature of 5,600K. Light of 5,600K is perceived by the human eye as white. For surgical lighting, experts recommend white light with a colour temperature between 4,000K and 4,500K. Thanks to a colour temperature of 4,300K, CHROMOPHARE lights produce white light with daylight quality, because it is in daylight that the human eye sees best.

SURGERY WITHOUT FATIGUE

It has been known for many years that light has physiological effects on the human organism. These effects occur through receptors located on the retina which control the amount of the hormone melatonine produced in the brain in response to stimulation with light. Melatonine induces fatigue in the human organism. The spectral effect curve of these receptors has been clear since 2001. Blue light inhibits the production of melatonine, helping us feel awake and active, while red light has no such inhibitive effect. During the evening and at nighttime melatonine is secreted freely, reducing circulatory activity and inducing tiredness. This mechanism is very relevant to surgeons operating during the evening and at night. Studies have shown that surgeons' performance and concentration is enhanced when operating under a surgical light of high colour temperature. In this way it has been possible to considerably reduce the risk of errors attributable to lack of concentration. As market and innovation leader, BERCHTOLD was the first company to study the influence of the spectral distribution of light on the operating team's performance and concentration. As a result, we have committed ourselves to providing lighting with a high colour temperature - to support the operating team and enhance the patient's safety.

While the blue sky during daylight is activating, the red light of the evening sun is comforting.

As can be seen in Plank's colour temperature curve, light of low colour temperature contains mainly yellow and red hues. Light only becomes white at approximately 4,300 K upwards. This is also where the colour temperature of daylight is located and it is in daylight that the human eye sees best.

ELIMINATING SHADOWS: THE POLYGON REFLECTOR

At the heart of every CHROMOPHARE light is a polygon reflector with a precise shape made up of hundreds of facets. Each single facet captures the light and casts it over the entire surgical field. In this way hundreds light fields are superimposed on one another, creating an absolutely homogeneous light column. The operation takes place directly in the middle of the light column, which measures between 120 cm and 125 cm (L1+L2) in height and reaches deep into the surgical field.

Due to the perfect design of the reflector facets and the size of the light emitting surface area, the space illuminated by the light column is not only as bright as daylight but also shadow-free. And it remains so, even when the surgeon's shoulders, hand or head covers part of the light source. To eliminate shadows, CHROMOPHARE lights are designed as monoreflector lights. This gives a large light emitting surface area, critical to avoiding shadows in the surgical field. Simultaneously, contours so essential for visual depth perception are retained.

A special depth reflector ensures that even deep cavities are optimally illuminated. The polygon reflector consists of hundreds of facets. Each single facet illuminates the entire surgical field.

Light is focused to give a homogeneous light column that reaches evenly far into the surgical field.

ELIMINATING RISK: MagicSwitch

When one bulb fails in a five-point lamp, 80% of the light is retained. When one bulb fails in a three-point lamp, 65 % of the light is retained. When the light source of a single-point bulb fails, it becomes dark. We have taken this challenge as an opportunity. Every CHROMOPHARE light is equipped with MagicSwitch (optional in CHROMOPHARE D 510), a switching mechanism which, in the event of a primary light source failure, instantly activates a substitute light source and within 200 milliseconds mechanically swings it into the optical center of the surgical light. This means that in reserve lamp mode you still get 100% light intensity and a light field identical to that of the primary light source.

		The main risk during an operation is surgical light failure. Intelligent technologies are aimed at reducing or eliminating this risk. If the light source should ever fail during an operation, a signal lamp immediately indicates the switch to reserve bulb mode. The defective lamp can then be easily replaced by the clinical staff without any hurry at the end of the day.
CHROMOPHARE surgical lights are easy to maintain, allowing you to replace the bulb in a few easy steps.

COOL

BERCHTOLD's CHROMOPHARE ThermoSorb filter system has long been valued by surgeons for its ability to filter out 99.5 % of the infrared radiation emitted by surgical lights. With our innovative BRITe technology we have now supplemented the ThermoSorb filter with a further filter layer which is located on the bulb itself. Infrared radiation is reflected back to the filament to generate more usable light. The surgeon gets the benefit of the same cool CHROMOPHARE light with the same power draw of 150 W - now up to 50% brighter than before.

EndoLite®

EndoLite solves all illumination problems associated with endoscopic surgery. At the touch of a button the CHROMOPHARE light can be switched from standard surgical lighting to a second type of light source integrated in the lamp head. This gives a soft, upward directed, indirect light.

VOICE AND TOUCH SCREEN CONTROL

Via an open interface, CHROMOPHARE surgical lighting systems can be docked to the operating platforms of room integration technologies of all leading manufacturers, including voice control and touch screen systems. No matter what the future brings - your CHROMOPHARE light is prepared.

		CHROMOPHARE lights are small and powerful and therefore easy to move from one place to another. The rail around the lighthead allows positioning the light from outside the sterile surgical field. CHROMOPHARE lights have a steam sterilizable handle and are hermetically sealed. The underside of every CHROMOPHARE light is made of a special safety glass. Only glass resists dulling from age, heat and disinfection agents.
CHROMOPHARE® D 660 With a light intensity of 160klx spread over a small light field of 17cm which can be enlarged to 30 cm the CHROMOPHARE D 660 is the light of choice for all procedures involving large surgical fields and deep cavities. The large polygon reflector with more than 700 high-reflecting polygons has the capacity to eliminate shadows and delight large operating teams. Mounted on easy moving arms rotatable through 360 ° around each of three axes the lighthead allows effortless positioning.
		CHROMOPHARE® D 540 The CHROMOPHARE D 540 achieves a light intensity of 145klx with a lighthead measuring no more than 52 cm. The light field size is adjustable from 17 cm to 28 cm. Its high light intensity and the air-flow optimized housing make the D 540 an ideal choice for rooms requiring small, space-saving lightheads.
CHROMOPHARE® D 510 The CHROMOPHARE D 510 is the world's most flexible surgical light. The basic version offers an excellent cost-benefit ratio. The D 510 gives the same high-quality, cool light typical of all BERCHTOLD surgical lights. Its light intensity reaches 130klx at high colour temperature and with accurate colour rendition. The unit can be custom-configured to perform all the functions you require. Whether you require brightness, control or focus adjustment, a rail for easy handling or a slot for camera mount, you configure your own CHROMPHARE D 510 and only pay for what you really need.

CAMERA ChromoVision is the BERCHTOLD camera system. It all began with the following functional specifications: optimal viewing angle, professional image quality and telepresence. The outcome: a mobile, high-performance camera system consisting of camera and control unit and equipped with the functions:

?autofocus ?automatic brightness control ?fully automatic white balance ?24 x zoom

for pinpoint-sharp surgical video images.

Due to the center positioning of the CHROMOPHARE, the camera delivers shadow-free images in all lighting situations. Of great convenience to the surgeon is the camera's rotatability. It can be turned on its own axis either manually or (optionally) by motor to deliver upright images throughout the procedure. The camera can also be operated externally from a PC from a RS 232 interface, from an surgical bus system or by voice control.

Camera with lamp handle: The ChromoVision camera can be integrated in the light with a single easy movement.
