General description The RevoLix DUO laser device integrates a combination of two laser sources: First, the RevoLix DUO laser device consists of a Thulium continuous wave laser with the wavelength of 2 μm (2.013 nm ±10 nm). It emits the laser radiation continuously (continuous wave – CW). Continuous wave emission can also be emitted intermittently (pulsed mode). In this case the maximum power of the pulses is not higher than the continuous wave power. On the other hand, the RevoLix DUO laser device consists of a pulsed Holmium:YAG laser. This pulsed laser has high pulse peak powers at the wavelength of 2.1 μm (2123 nm ± 10 nm). The wavelengths of both lasers are in the invisible infrared range. The laser radiation is delivered by means of a fibre made of silica. The distal end of the fibre is guided by a suitable applicator. For clinical applications, various applicators are available that are tailored to a specific application. The laser device is operated via the operating panel provided with a display. The laser emission is activated by a footswitch. The RevoLix DUO laser devices comply with the "Essential requirements of the European Medical Devices Directive 93/42/EEC".

Visual and audible signals The selected operating state is accompanied by specific audible and visual signals emitted by the laser device. The laser warning lamp in the operating panel (Fig. 6 [2]) is the visual signal for laser readiness and laser emission. Depending on the operating state of the laser device, the laser warning light provides flashing signals in the colors red and yellow (see Tab. 5). In addition to the laser warning lamp, audible signals are emitted to indicate operating conditions. Thus, in addition to the visual signal for laser emission display, a permanent or periodic beep - depending on the type of emitted laser radiation - can be heard. Switching from the STANDBY mode to READY is also accompanied by a short confirmation tone. Tab. 5: Visual and audible signals
Operating condition
visual / audible signal
START-UP
During system test the laser warning lamp lights up briefly indicating the internal functional test. At the same time, the start-up melody of the laser device sounds.
Change between STANDBY - READY
If the ready button on the operating panel is pressed, the laser device switches from the STANDBY operating mode to READY. This will be followed by a brief audible message and the laser warning lamp will flash red four times at a frequency of 2 Hz. After this sequence, the visual signal of the laser warning lamp changes to a steady red glow.
EMISSION (STONE: PULSED)
During the emission of pulsed laser radiation, a periodic signal tone can be heard. The laser warning lamp alternately lights red and yellow - according to the selected pulse repetition rate (up to a maximum of 10 Hz).
EMISSION (TISSUE: CW)
During the emission of CW laser radiation, a permanent audible signal is heard. At the same time the laser warning lamp illuminates alternately red and yellow at a constant frequency of 2 Hz.
