Litho
Surgical Laser System
Litho surgical unit is based on Holmium (Ho:YAG) laser with emission at two micron (2100nm) wavelength. This wavelength is highly absorbed by water and biological tissue.
The Litho automatically adjusts the correct pulse duration depending on the operating mode and sets the values of energy and repetition rate. When it is operating in a short pulse emission mode, it is highly effective in the fragmentation of calculi and the hard tissue ablation. In long pulse emission, it is highly effective in cutting soft tissue providing excellent hemostasis and coagulation with minimal damages of surrounding tissue, due to its low penetration depth. Because of the high radiation absorption by water, the application in a hydrous solution environment is highly safe.
Technical features
The Litho laser system has state-of-the-art technical specifications, which represent a gold standard in surgical market:
Pulse energy: it is possible to set up to 5 J per pulse. The pulse energy is related to the fragmentation efficacy. It is ideal for hard stone treatments.
Repetition rate: the maximum repetition rate is 30 Hz. By using the high repetition rate and low pulse energy, a fine fragmentation is secured. The DUSTING effect function assures the effective dusting even at high repetition rates.
Pulse duration: the unit provides a broad range of pulse durations. Due to this feature, the system could select the most suitable modality of preset parameters on the application menu (HARD STONE-DUSTING-ABLATION-COAGULATION).
The maximum effectiveness in ablation and fragmentation is assured also when using flexible ureteroscopes.
