Multi-wavelength laser acupuncture instrument

Abstract

The invention provides a multi-wavelength laser therapeutic instrument. A plurality of semiconductor laser light sources with different wavelengths are integrated by using a diffraction grating, and a laser cavity is formed outside each semiconductor laser unit through each semiconductor laser and an output coupling mirror for two ends of the grating in a light path; and after a light beam emitted by each semiconductor laser passes through the diffraction grating, one part of transmission light is reflected by the output coupling mirror and fed back to the light path, laser oscillation is formed to enable the wavelength to be locked and unchanged, and the other part of light transmits the output coupling mirror to be output so as to enter one corresponding path of multiple paths of optical fibers for irradiating acupuncture points. Therefore, laser with a plurality of different wavelengths is integrated in one laser acupuncture instrument so as to meet the requirements of multi-acupuncture-point treatment and different acupuncture depths of different acupuncture points.

Description

technical field [0001] The invention relates to the field of laser therapy, in particular to a laser acupuncture instrument. Background technique [0002] In the 1960s, after Mester proposed that low-intensity lasers had biostimulation effects, the biostimulation effects of low-intensity lasers were gradually confirmed. Acupuncture is a treatment method of traditional medicine. It refers to the use of different needles to stimulate the acupoints of the human body through certain techniques, stimulate the qi and blood in the meridians, and regulate the overall function. Since the biostimulation effect of laser was discovered, more and more researches have focused on using laser beams instead of needles to effectively stimulate acupuncture points. [0003] Compared with traditional filiform needle stimulation, laser acupuncture has its unique advantages: (1) There are more types of energy information input into the human body through laser acupuncture, and there are more ener...

Problems solved by technology

If each semiconductor laser is equipped with an optical fiber suction cup to make a laser acupuncture instrument with a single light source, the doctor needs to use dozens of independently working laser acupuncture instruments with different wavelengths at the same time during each treatment. Contains a set of independent laser light source, light transmission system, fiber optic suction cup, and individually controls the switch status of each acupuncture instrument, which is very inconvenient for doctors
