Applications For the removal of Tattoo Ink, Epidermal Pigmented Lesions, Dermal Pigmented Lesions, and Vascular Lesions.Featuring
Product Goal Since their introduction, pulsed laser systems have been plagued by high purchase and operating costs, reliability problems, and limited applications. In turn, these problems directly interfere with the ability of most physicians to justify the use of a pulsed laser in their practice. Hoya ConBio Biomedical, Inc. was founded with the goal to provide the most advanced laser to the Dermatology and Plastic Surgery marketplace. ConBio's founders knew the next generation laser must meet the physician's demand for a low cost, yet reliable, multi-application pulsed laser. The goal was finally met in December 1991 when the Medlite Q-Switched, Frequency Doubled Nd:YAG laser was introduced to the medical community. Low Cost The initial purchase price of the Medlite II is available at up to one half the cost of other pulsed laser systems on the market. Further substantial savings are realized when installation and operating costs are included. Installation of the Medlite II requires only standard 110 Volt, single phase household current, available in any office. All other pulsed lasers require at least 220 Volt electrical power, typically not standard in most offices. Other systems also require either an additional water and drain system for cooling or external ducting of heat exhaust. Costly outside contractor work is never required during a Medlite II installation. Other pulsed lasers require ongoing charges which significantly add to the expense of operating a laser. A ruby laser typically adds costly "per shot" charges. This means, in addition to the initial purchase price, the physician continues to pay for each pulse used during treatments. Dye lasers increase operating costs by requiring expensive dye refills after every 2 hours of treatment. With the Medlite II, there are no costly "extras" that further burden your operating expenses. Reliability The Medlite II is based upon over fifteen years of solid state research with a long and proven track record in the scientific community. Shipments of the Medlite began in April 1992. Reliability reports from ConBio's rapidly growing list of customers are readily available. We encourage you to contact our Medlite II users directly to learn for yourself. ND:YAG The Neodymium Yttrium Aluminum Garnet laser (ND:YAG) is a solid state system, used for many years in both the scientific research and medical communities. The Medlite II is uniquely set apart from the common ND:YAG in that it is Q-Switched and Frequency Doubled. The system consists of three main components: a) The power supply, used to provide the proper voltage and current to the laser system, b) The water cooling system, used to remove heat from the power supply and c) The optical bench, consisting of the YAG rod, flashlamp, various mirrors, frequency doubler and articulated arm. The lasing action of the ND:YAG occurs when first the flashlamp is excited by a high voltage electrical pulse from the power supply. The excited flashlamp then emits an intense broad-spectrum light. The YAG rod absorbs most of this light and then releases the energy as laser light at 1064 nm. Q-Switched The Q-Switch (Pocket Cell) acts as an extremely high speed shutter. Its role in the cavity is to prevent the light from the "excited" ND:YAG rod from reaching the rear mirror (total reflector) of the laser cavity until the ND:YAG rod can store-up a large amount of energy. A short voltage pulse is applied to the Q-Switch which changes its ability to pass polarized light. This change allows a single, extremely high energy (35 megawatts) and extremely short (10 nanoseconds), pulse of light to exit the cavity. The Q-Switch can be set by the display panel to release the light at pulse rates of 1, 2, 5 and 10 pulses per second or single shot. Frequency Doubler The Medlite II's Frequency Doubler can be enabled by the press pad on the display panel to change the 1064 nm (infrared) light to a second wavelength at 532 nm (green). The wavelength of light is the distance, measured in nanometers (nm), between the intensity peaks of the lightwave. The frequency of the light is the number of intensity peaks in one second. When the laser light is passed through the Frequency Doubler, a solid crystal, the lightwave doubles in frequency (or peaks per second). The wavelength (distance between the intensity peaks) is thereby cut in half and 1064 nm infrared is converted to 532 nm green. The Medlite II's dual wavelength
provide excellent treatment capabilities. The 1064 nm line is able to
target dark ink chromophores and dark dermal elanocytes with very low
interference from epidermal melanin. In contrast, melanin absorption is
very high at the 532 nm line, thereby very well absorbed for the removal
of epidermal pigmented lesions. In addition, oxyhemoglobin is also very
well absorbed by the 532 nm line for vascular lesion removal.
