Design of Multi-Wavelength Low-Level Laser Therapy Device for Assisting Bone Reconstruction Applications

One of the main focus areasin human body reconstruction is the regeneration of bone tissue in different body zones by using variousreconstruction applications. In the last two decades, different efforts have been undertaken for developing new bone reconstruction methods,andsupportingtechniques for stimulating bone healing mechanisms. It has been shown that during different Bone Reconstruction Applications(BRA), the presence of laser light could enhance the bone regeneration and healing mechanisms, while shortening the treatment time and improving the quality of newly formedbone tissue. The application of Low-Level Laser Therapy(LLLT)has recently been used for newbone reconstruction applicationsin different body parts,including the tibia, fibula, femur, humerus, radius, and mandible. It wasshown that by applying a low-power laser light during the bone healing procedure in different treatments, an improved quality of regenerated bone tissuewas evident,while accelerating bone healing mechanisms. However, only a few studies have been performedwith regard to the development of specific LLLT devices for such advanced bone reconstruction procedures. More research needs to be done towards developing anideal LLLT device to be used in different bone reconstruction techniques. The purpose of this research is to design a novel multi-wavelength LLLT device with controllablelaserlight intensity. In addition, by using such a mechanism,generating the laser light in single-and multi-wavelengthsin predetermined working sequences is possible. The design specifications and simulation results have shown that the proposed systemis functional while meeting all required specifications in terms of generating a single-or multi-wavelength laser light,with controllable power intensity. Therefore, in future developments, the proposed system could be used during BRAfor assisting the treatment.
