semiconductor laserFunction and principle of therapeutic apparatus

The low-intensity laser of the semiconductor laser treatment instrument irradiates the blood, which can cause a series of biochemical reactions in the human body, and improve and restore the physiological function of the blood by promoting blood circulation and calming the blood. It has a significant effect on postoperative analgesia. The therapeutic apparatus is safe and reliable, easy to operate and effective. It is highly respected in clinical medicine and is one of the indispensable treatment tools for clinical surgery.

semiconductor laserThe therapeutic machine can activate or induce T, B lymphocytes and macrophages to produce cytokines, activate the systemic immune system through lymphocyte circulation, enhance the phagocytic function of macrophages, and improve the role of non-specific and specific immunity. Semiconductor laser irradiation can inhibit or reduce inflammation and pain.

Improve local blood circulation. Semiconductor laser directly irradiates the pain site, blood flow decreases, or indirectly irradiates the sympathetic ganglia, and controls this range, which can lead to increased blood flow, promote the metabolism of pain-causing substances, and relieve pain.

Activates the endorphin system. After the body is irradiated by the semiconductor laser, it can increase the metabolism of brain peptides, accelerate the release of brown substances in the brain, and relieve pain.

Inhibition of nervous system conduction. Semiconductor lasers suppress not only the conduction velocity of the stimulus, but also the intensity and frequency of the stimulus. Lasers can inhibit peripheral nerve impulses, conduction velocity, intensity and impulse frequency caused by painful stimuli

Activate the downlink suppression system. Laser irradiation stimuli can be transmitted upward to the posterior horn of the spinal cord while activating the descending inhibitory system.

Tissue repair. Laser irradiation can promote the growth of new blood vessels and tissues, and stimulate protein synthesis. Blood vessels are one of the basic components of tissue and a prerequisite for wound healing. The more abundant the blood vessels in the tissue, the more sufficient the oxygen supply of the tissue, which helps repair the metabolism and maturation of cells in various tissues, and promotes the production, deposition and cross-linking of collagen fibers.

Biological regulation. After laser irradiation, it can enhance the immune function of the body and realize the two-way regulation of blood cells.

semiconductor laserThe working principle and characteristics of the device. The working principle of a semiconductor laser is the excitation mode. The use of semiconductor materials, that is, the use of electrons in the band transition light. Two parallel mirror surfaces formed by the cleavage surface of semiconductor crystal are used as mirrors to form a resonant cavity, which can make light oscillation, feedback, radiation amplification of generated light and output laser light. The advantages of semiconductor lasers are small size, light weight, reliable operation, low power consumption and high efficiency. Semiconductor laser packaging technology is mostly developed and evolved on the basis of discrete device packaging technology, but it has great particularity. Typically, the die of the discrete device is encapsulated in a package, and the role of the package is mainly to protect the die and complete the electrical interconnection. The semiconductor laser package is used to output electrical signals, protect the normal operation of the mold, and output visible light. Due to the design and technical requirements of electrical and optical parameters, it is impossible to simply use the packaging of semiconductor laser discrete devices.
