Description

Technical Field

[0001] The utility model belongs to the technical field of laser therapeutic apparatuses, and in particular relates to a handheld composite mode high-energy laser therapeutic apparatus. Background Art

[0002] Clinical studies have shown that laser therapy can be used for analgesia, anti-inflammation, and wound healing. Compared to traditional low-energy laser therapy (power less than 0.5W), high-intensity lasers offer a larger irradiation area, deeper penetration, and shorter treatment times, resulting in better therapeutic outcomes. They are non-invasive, side-free, and can be used long-term. Currently, high-intensity laser rehabilitation devices all utilize a main unit and a treatment handle, making them difficult to use handheld. Due to limitations in the handheld structure and heat dissipation drive capabilities, increasing the laser's power is difficult. Utility Model Content
