Dual wavelength laser treatment device

Abstract

Embodiments of the invention include a compact, lightweight, hand-held laser treatment device that combines the emissions of two separate laser energy sources into a common optical pathway for improved therapeutic effect. In some embodiments, the device includes a housing having separate first and second laser sources disposed within the interior thereof. In some embodiments, the laser energy emissions from the two internal laser sources can be individually or concurrently transmitted to a delivery tip of the device via a laser transmission path also defined within the interior of the housing. In some embodiments, the structural and functional features of the first and second laser sources, in concert with the unique architecture of the laser transmission path, can be configured to provide efficacy and efficiency in the operation of the device within the spatial constraints of the lightweight, hand-held housing thereof.

AI Technical Summary

Benefits of technology

The device achieves improved tissue treatment efficacy with enhanced ablation depth, reduced charring, and synergistic bactericidal, bio-stimulation, and pain reduction effects by combining the emissions of a high peak power solid state laser and a high average power diode laser, offering greater precision and control compared to single laser source systems.

Problems solved by technology

Due to the high power requirements and attendant safety concerns, the laser energy source is oftentimes located away from the operator and the patient.

Further, the intensity of the emission, along with the duration of the pulse, must be set to ensure that the tissue does not boil or vaporize (which can lead to greater injury and hemorrhaging).
