Ultrashort wave therapy instrument is a traditional treatment instrument. It uses the tube oscillation to generate ultrashort wave high frequency electric field for treatment. The capacitor electrode outputs energy, and the affected part is placed between the electrodes. Under the action of a high-frequency electric field, the molecules and ions of the diseased part vibrate at their parallel positions, and they rub against each other to produce a thermal effect. This thermal effect uniformly heats the surface and deep tissues of the affected area, which can enhance vascular permeability, improve microcirculation, regulate endocrine, strengthen the metabolism of the tissue body, reduce the excitability of sensory nerves, therefore achieving bacteriostasis, anti-inflammatory, analgesic, promoting blood circulation and repair, and strengthening the body's immune treatment purpose.
