The LASERNEEDLE technology uses laser of Class 3B to supply irradiated tissue with additional energy, without having the thermal tissue-damaging effect – other than that in case of powerful Class 4 laser.
For a successful effect the laser power must be beyond a threshold value. Weak lasers do not penetrate deep enough into the tissue to achieve a therapeutic effect. On the contrary, strong Class 4 lasers are too powerful and bear the risk of thermal damage of the irradiated tissue.
The LASERNEEDLE technology combines the class 3B laser with a special High Power Density Technology (HPD) and thus reaches the necessary laser power without the risk of thermal effects.
High Power Density (HPD)
The special LASERNEEDLE HPD-LASER (High Power Density) focuses a low power laser and brings its radiation through a special flexible optics directly to the site of application. This leads to an extremely high luminance (the number of photons per area) which stimulates biological regeneration processes in the tissue without thermal side effects.
Weak Laser Strong Laser HPD-Laser
The LASERNEEDLE technology is based on penetrating laser light stimulating the following biochemical processes in the human body, which are regenerative. The laser light acts
In the application of violet light, a bactericidal effect can be achieved (also see "effects of light", on right hand column).
- precise irradiation of the affected areas by attaching the laser channel onto the skin (can be done without supervision)
- surface irradiation by bundling the laser channels in the laser shower
- Allows bundling of up to nine different laser channels to irridate larger areas
- Allows the combination of different wavelengths (colors)
- operating in continuous wave or pulsed mode
The mode of action of laser treatment is dependent on the wavelength of the laser used.
Red and infrared light
Red and infrared laser directly stimulate cellular energy metabolism in the cell organelles mitochondria and
- increase the production of the energy carrier adenosine triphosphate (ATP), which is necessary for proliferation,
- induce nitric oxide (NO), which stimulates the blood circulation and thus nutrient supply,
- induce reactive oxygen species (ROS), which at a low concentrations regulate gene expression, which in turn i.a. triggers analgesic effects.
Violet light on the opposite has an antibacterial effect on bacteria containing porphyrins. These include many known pathogens. There violet light excites only in bacteria the production of so high concentrations of reactive oxygen species ROS, that the bacterial cells are selectively destroyed.
A major application is wound healing, where pathogenic bacteria are destroyed while remaining the surrounding host tissue intact.
