Phototherapy device for cervical spondylosis

Abstract

The invention belongs to the technical field of medical instruments, and specifically relates to a phototherapy device for cervical spondylosis. The phototherapy device of the invention comprises a light illumination module, a light path adjustment module, a power supply module and a light adjustment module. The light illumination module is composed of a flexible circuit substrate and a light source for illuminating target cells. The light path adjustment module diffuses light emitted by the light source and distributes the light in a light illumination area uniformly. The light adjustment module is used to set pulse light wavelength, pulse light power and illumination time. Compared with existing therapeutic apparatuses, the phototherapy device of the present invention realizes higher-intensity illumination and has higher penetration depth in tissues. The phototherapy device of the present invention enhances activity of macrophages through an appropriate light mode, accelerates removal of necrotic debris of tissues and cells at lesions of a body while enhancing activity of microglial cells and promoting repair of the central nervous system. In addition, the phototherapy device ofthe present invention uses pulse width modulation to generate pulse light with an extremely strong transient power, thereby avoiding the problems such as small illumination area and reduced penetration depth of laser light in the tissues in infrared-type therapeutic instruments.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a phototherapy device. Background technique [0002] With the continuous improvement of science and technology, people spend more and more time on electronic products such as computers and mobile phones, resulting in more and more cases of cervical spondylosis not only among middle-aged and elderly people, but also among white-collar office workers and students. Today, cervical spondylosis has become one of the most common diseases in the world. Due to long-term strain of the cervical spine, intervertebral disc herniation and other reasons, the cervical spinal cord, nerve roots, vertebral arteries, and crossed nerves are compressed, resulting in various types of cervical spondylosis. [0003] At present, there are two types of common phototherapy equipment for treating cervical spondylosis: infrared type and low-intensity weak laser type. Among them, infrared...

Problems solved by technology

Among them, infrared equipment mainly uses the action of radiant heat to dilate and congest local skin capillaries, accelerate blood flow, enhance cell metabolism and reduce the sensitivity of nerve endings. However, most of the infrared rays are absorbed by the epidermis, resulting in penetration. The tissue depth is low, and the treatment effect is not good; the low-intensity weak laser equipment can restore the internal and external balance of the vertebrae by dilating the arteries and improving the blood circulation of the shoulder and other tissues, and relieve the compression of the spinal cord by the neck muscle spasm. As the temperature rises, the laser penetration depth decreases, and at the same time, the biostimulation effect is greatly transformed into a thermal effect, resulting in a significant shortening of the effective treatment time. At the same time, the equipment has a small light area, and it is difficult to completely cover the treatment area, so the effect still needs to be improved.
