摘要： An apparatus for cooling tissues which are treated with an energy-based device, such as a laser, is disclosed. The apparatus comprises a spray nozzle which generates an atomized liquid spray for the treatment area, wherein the atomized liquid spray is based on a mixture of liquid and gas. Further, the spray nozzle comprises at least one liquid outlet which ejects a liquid, and at least one gas outlet which ejects a gas stream. Besides, the apparatus for cooling comprises at least one delivery means for delivering pressurized gas to the spray nozzle; and a pumping means for the liquid, wherein the pumping means is configured to operate in pulses.

摘要： An apparatus for tissue regeneration is provided. The apparatus comprises means for generating at least one laser pulse comprising a wavelength; and means for directing the at least one laser pulse onto a tissue surface of a human or animal body, wherein the means for generating comprises control means to ensure that a sum of the pulse energies of the at least one laser pulse is selected so that the corresponding fluence on the tissue surface heats the tissue surface up to a maximal temperature T max between 70 °C and a tissue boiling temperature T b . Further, the means for generating of the apparatus are adapted so that a delivery time t ed of the at least one laser pulse (during which the second half of the pulse energy is delivered) is sufficiently short so that, given the wavelength and thus a corresponding penetration depth δ of the at least one laser pulse, a thermal exposure time t exp of the tissue surface is shorter than 900 microseconds. Here, the thermal exposure time t exp of the tissue surface is defined as a time interval in which the temperature of the tissue surface is above T o + (T max - T o )/2, wherein T o defines the initial temperature of the tissue surface, before the laser pulse arrives.

摘要： The invention relates to a cleaning system being configured for cleaning, including fragmentation, debridement, material removal, irrigation, disinfection and decontamination, of cavities (2) filled with a liquid (3). The cleaning system comprises an electromagnetic radiation system and the liquid (3). A treatment handpiece (7) and its exit component (8) are configured to irradiate the liquid (3) within the cavity (2) with the radiation beam, wherein a wavelength of the radiation beam is chosen for significant absorption of the radiation beam in the liquid (3). The electromagnetic radiation system is adapted to generate a first vapor bubble (18) within the liquid (3) by means of a corresponding first pulse (p a ) and a second vapor bubble (18') within the liquid (3) by means of a corresponding second pulse (p b ) at a location different to the location where the first vapor bubble (18) is present at the time of generating the second vapor bubble (18'). The electromagnetic radiation system further comprises a feedback system (9) to determine a bubble oscillation intensity. Adjusting means (10) are provided for adjusting the pulse repetition time (Tp) as a function of the determined bubble oscillation intensity. The pulse repetition time (T p ) is adjusted such, that the onset time (t 0b ) of the second vapor bubble (18') is within the first contraction phase of the first vapor bubble (18), when the first vapor bubble (18) has contracted from its maximal Volume (V max ) to a size in a range from about 0.7 to about 0.1 of the maximal Volume (V max ).
