RESEARCH ON THE APPLICATION OF A LOW-POWER SEMICONDUCTOR LASER DEVICE WITH TWO WAVELENGTHS FOR THE TREATMENT OF ANAL HAEMORRHOIDS

Abstract

The device is applied in the clinical treatment by low-power semiconductor laser, which has been used in developed countries including Vietnam for many recent decades. The outstanding benefit from this device is using the high monochromatic wavelength and relevant emission power to create a biostimulation effect. The Laser device is designed with the simultaneous coordination of two wavelengths of 780nm and 940nm, along with a frequency modulation customized for each type of disease, to support physical treatment, especially in the treatment of anal haemorrhoids. The system of photo-acupuncture and phototherapy with low-power semiconductor laser is made with a capacity of 0 to 14mW, using a single emitter or a beam head consisting of 7 laser diodes, combining two wavelengths of 940nm and 780nm. The device allows the modulation frequency to be adjusted from 5HZ to 100Hz, suitable for bio-frequencies to optimize its treatment.
