Lasers – There are different types of laser devices for applying LLLT
Laser pens or point lasers are employed for the treatment of small areas or to stimulate acupuncture, trigger points, and pain points.
Ideally, the treatment tips can be replaced, e.g. by fibre optic attachments with which hard-to-reach orifices in the body can be accessed (e.g. intra-oral or intra-auricular attachments).
Modern laser pens are cordless and have a display which indicates therapy time, dosage, laser output, and battery status. When a target dosage is entered, the therapy time is calculated automatically.
Laser pens are available with and without preset frequencies, so they are either suitable for resonance therapy or not.
Laser showers are extended area lasers for the treatment of fairly large areas. Modern equipment includes displays which show therapy time, dosage, laser power, and battery status. A few laser showers moreover offer the option of selecting frequencies so that frequency therapy can also be performed in extended area treatment.
Area lasers can irradiate areas of up to 55 cm2. Depending on the field of application, large or small laser showers are used.
Area laser units are usually guided manually and should be in contact with the skin. However, they can also be kept in place with a tripod, which always means that there is a distance between laser beam outlet and area to be treated. In this case the treatment time must be adjusted accordingly.
Laser combs are extended area lasers with so-called comb attachments. In an actual laser comb, these attachments are no mock-ups – rather, all comb tips contain fibre-optic cables. This is the only way that a laser comb can serve its purpose and, e.g. in the treatment of animals with dense fur, ensure sufficient radiation density.
laser needle acupuncture
While acupuncture points can only be irradiated successively with a laser pen, multi-acupuncture laser devices have many fibre-optic cables, which allows for simultaneous stimulation.
These devices, which are often also called laser needle systems, have therapy displays on which the therapy time, dosage, and laser output can be entered. The various fibre-optic cables and light needles can be programmed separately.
In most cases, however, it is also possible to treat extended areas with multi-acupuncture systems. To this end there are, e.g., plug-in panels available to which the fibre optic cables can be attached. Contrary to conventional laser showers, the number of laser diodes, the size of the treatment area, and the radiation density can thus be modified individually. These “laser spots” are either held in place or can be secured with tripods.
Invasive laser therapy systems
Cold laser light cannot only be applied transcutaneously but also be sent directly into the bloodstream (intravenously), a joint (intra-articularly) or a tissue (interstitially). To this end an optic fibre is inserted directly into a blood vessel, the joint, or the tissue via a cannula. The optic fibre is connected with the laser diode via a fibre-optic cable. In this manner the laser light reaches the site of the damage directly and therefore with greater energy density.
